Super Avana

By Y. Masil. College of New Rochelle.

You can only keep this confdential fr today fr enhancing therapy cheap super avana 160mg otc, but then disclosure to the parents must be demonstrated and documented buy super avana 160mg on line. You may keep this confdential fom the parents but you must call the partner to notify him of the infction order discount super avana on line. The physician fnds injuries consistent with physical abuse while exam­ ining a 13 years old, but the patient fears frther injury if the abuse is reported. A depressed teenager reports a strong desire to kill herself and that she has secretly obtained a gun that she keeps in her bedroom. An undocumented immigrant patient has active tuberculosis and fears deportation if the illness is reported. Because of medical confdentiality, a minor is able to consent to any medi­ cal therapy she chooses without the consent of her parents or guardian. Although consent requirements fr abortion services vary depending on the state, most states either have some frm of required consent fr abor­ tion services to minors or a mandatory wait period. There are no states in which a minor can obtain an abortion without the consent of a parent or guardian. The law does not require the disclosure of sensitive medical infrmation to parents. A clinician must use his or her best judgment when deciding whether to disclose medical infrmation. More importantly, the physician should recog­ nize the importance of confdentiality when treating patients and encourage open communication between adolescents and parents when it is reasonable to do so. Partner notifcation can occur by patient refrral or by health depart­ ment staf 8. All states have laws mandating the reporting of certain conditions, even if the patient objects. The specifc conditions may vary fom state to state, so the physician must be aware of the rules where he/she practices. Child abuse must be reported to appropriate authorities if suspected in all states. Simi­ larly, certain infctions, such as active tuberculosis, must be reported to public health ofcials. Active suicidal ideation, especially if there is a plan and access to agents necessary to implement the plan, may lead the physician to intervene to prevent the action. Emancipation implies that the patient is able to make decisions regarding health-related issues but does not give the patient the right to vote, consume alcohol, or use tobacco products if the patient is not of legal age. Only 12 states currently allow a minor to have an abortion without the consent of or notifcation to parents. However, the clinician should attempt to administer confidential health care to minors seeking care fr sensitive medical issues when it is saf and appropriate to do so. Confdential health care fr adolescents: position paper of the Society fr Adolescent Medicine. Adolescent patient confidentiality: whom are we kidding [editorial Jr]Adolesc Health. She reports feling "dizzy" on and off fr the past year; the dizziness is associated with weakness that has been worsening fr the past month. Review of systems is signif­ icant fr knee pain, fr which she frequently takes aspirin or ibuprofn; otherwise the review of systems is negative. She has no significant medical history and has not been to a doctor in several years. She had a normal well-woman examination and screening colonoscopy about 5 years ago. On examination, her blood pressure is 150/85 mm Hg; her pulse is 98 beats/min; her respiratory rate is 20 breaths/min; her temperature is 98. The remainder of the examination, including respiratory, cardiovascular, and nervous systems, was normal. Considerations A 65-year-old woman who has developed worsening dyspnea and palpitations over 1-week period of time needs to be evaluated fr cardiac and respiratory problems despite the gradual onset of symptoms. Specifcally, in a postmenopausal woman, signs and symptoms of angina or acute myocardial infrction may not always have a typical presentation. That the patient has been feeling weak and has conjunctival pallor warrants testing fr anemia. Assuming that the initial workup fr cardiac and pulmonary causes is negative and that the hemoglobin and hematocrit levels are low, a thorough evaluation fr the cause of the anemia is necessary. If this patient was fom a developing country, the possibility of intestinal parasites would need to be considered. Weight loss, lymphadenopathy, and coagulopathy may warrant evaluation fr nongastroin­ testinal malignancies, such as leukemias or lymphomas. These diferences are reportedly a result of biologic, not socioeconomic, diferences. Most studies show the rate of anemia to be higher in men than women and there is increasing evidence fr anemia as an independent risk fctor fr increased morbidity and mortality and decreased qual­ ity of life (Level B recommendation). Cinical Presentation Fatigue, weakness, and dyspnea are symptoms that are commonly reported by elderly persons with anemia. For example, the reduced oxygen-carrying capacity of the blood as a consequence of anemia may exacerbate dyspnea associated with congestive heart filure. Conjunc­ tvl pallor is recommended as a reliable sig of anemia in the elderly and commonly noted i patents with hemogobin less than 9 g/dL. Glossitis, decreased vibratory and positional senses, ataia, paresthesia, confsion, dementia, and pearly gray hair at an early age are signs sug­ gestive of vitamin B12-defciency anemia. Profund iron defciency may produce koilony­ chias (spoon nails), glossitis, or dysphagia. Jaundice can be a clue that hemolysis is a contributing fctor to the anemia, whereas splenomegaly can indicate that a thalas­ semia or neoplasm may be present. Further laboratory studies would be indicated based on the results of the initial tests and the presence of symptoms or signs suggestive of other diseases. Other causes of microcytic anemia include thalassemias and anemia of chronic disease. In the elderly, iron defciency is fequently caused by chronic gastrointestinal blood loss, poor nutritional intake, or a bleeding disorder. The presence of macrocytic anemia, with or without the symptoms previously mentioned, should lead to frther testing to determine B12 and flate levels. Folate defciency anemia is usually seen in alcoholics, whereas B12-defciency anemia mostly occurs in people with pernicious anemia, a history of gastrectomy, and diseases associated with malabsorption (eg, bacterial infection, Crohn disease, celiac disease). Under normal conditions, the body stores 50% of its B12 (2-5 mg total in adults) in the liver fr 3 to 5 years. B12 defciency can be distinguished clinically fom flic acid defciency by the presence of neurologic symptoms. In the elderly, anemia of chronic infammation (frmerly known as anemia of chronic disease) is the most common cause of a normocytic anemia. Anemia of chronic infammation is anemia that is secondary to some other underlying condi­ tion that leads to increased inflammation and bone marrow suppression. Along with causing a normocytic anemia, anemia of chronic infammation can also present as a microcytic anemia.

Dexmedetomidine undergoes rapid and complete hepatic metabolism super avana 160 mg with amex, followed by excretion in the urine discount super avana 160mg with visa. If these cardiovascular effects are too intense order super avana with amex, they can be managed in several ways, including (1) decreasing or stopping the infusion, (2) infusing fluid, and (3) elevating the lower extremities. Drug Interactions Dexmedetomidine can enhance the actions of anesthetics, sedatives, hypnotics, and opioids. Preparations, Dosage, and Administration Dexmedetomidine [Precedex] is supplied in solution (100 mcg/mL), which must be diluted to 4 mcg/mL before use. For intensive care sedation, treatment consists of a loading dose (1 mcg/kg infused over 10 minutes) followed by a maintenance infusion of 0. For procedural sedation, treatment typically consists of a loading dose (1 mcg/kg infused over 10 minutes) followed by a maintenance infusion of 0. Epidural Anesthesia Epidural anesthesia is achieved by injecting a local anesthetic into the epidural space (i. A catheter placed in the epidural space allows administration by bolus or by continuous infusion. After administration, diffusion of anesthetic across the dura into the subarachnoid space blocks conduction in nerve roots and in the spinal cord. Diffusion through intervertebral foramina blocks nerves located in the paravertebral region. With epidural administration, anesthetic can reach the systemic circulation in significant amounts. As a result, when the technique is used during delivery, neonatal depression may result. Spinal (Subarachnoid) Anesthesia Technique Spinal anesthesia is produced by injecting local anesthetic into the subarachnoid space. Spread of anesthetic within the subarachnoid space determines the level of anesthesia achieved. Movement of anesthetic within the subarachnoid space is determined by two factors: (1) the density of the anesthetic solution and (2) the position of the patient. Adverse Effects The most significant adverse effect of spinal anesthesia is hypotension. Blood pressure is reduced by venous dilation secondary to blockade of sympathetic nerves. Autonomic blockade may disrupt function of the intestinal and urinary tracts, causing fecal incontinence and either urinary incontinence or urinary retention. The prescriber should be notified if the patient fails to void within 8 hours of the end of surgery. These “spinal” headaches are posture dependent and can be relieved by having the patient assume a supine position. Dosing may consist of an initial weight-based bolus followed by a weight-based infusion titrated to laboratory results. Whether or not a bolus is indicated depends on the indication for treatment and the facility policy. Low-Dose Unfractionated Heparin Therapy Heparin in low doses is given for prophylaxis against thromboembolism in hospitalized patients. Doses of 5000 units are given subcutaneously every 8 to 12 hours depending on patient weight. Protamine Sulfate for Heparin Overdose Protamine sulfate is an antidote to severe heparin overdose. These groups bond ionically with the negative groups on heparin, thereby forming a heparin-protamine complex that is devoid of anticoagulant activity. Neutralization of heparin occurs immediately and lasts for 2 hours, after which additional protamine may be needed. Dosage is based on the fact that 1 mg of protamine will inactivate 100 units of heparin. Hence, for each 100 units of heparin in the body, 1 mg of protamine should be injected. The drug is a synthetic drug chemically related to hirudin, an anticoagulant isolated from the saliva of leeches. Bivalirudin is given in combination with aspirin, clopidogrel, or prasugrel to prevent clot formation in patients undergoing coronary angioplasty. In one trial—the Hirulog Angioplasty Study—bivalirudin plus aspirin was compared with heparin plus aspirin. In a subgroup of patients— those with postinfarction angina—bivalirudin was significantly more effective than heparin. Adverse Effects The most common side effects are back pain, nausea, hypotension, and headache. Other relatively common effects (incidence greater than 5%) include vomiting, abdominal pain, pelvic pain, anxiety, nervousness, insomnia, bradycardia, and fever. However, compared with heparin, bivalirudin causes fewer incidents of major bleeding (3. Coadministration of bivalirudin with heparin, warfarin, or thrombolytic drugs increases the risk for bleeding. Bivalirudin is eliminated primarily by renal excretion and partly by proteolytic cleavage. The half-life is short (25 minutes) in patients with normal renal function but may be longer in patients with renal impairment. However, the drug has one disadvantage: bivalirudin is more expensive than heparin. One single-use vial, good for a full course of treatment, costs about $1000, compared with $10 for an equivalent course of heparin. However, the manufacturer estimates that reductions in bleeding and ischemic complications would save, on average, $1000 per patient, which would offset the greater cost of bivalirudin. Bivalirudin works as well as heparin, is safer, and may be equally cost effective—and hence is considered an attractive alternative to heparin for use during angioplasty. If necessary, bivalirudin may be infused for up to 20 additional hours at a rate of 0. In clinical trials, argatroban reduced development of new thrombosis and permitted restoration of platelet counts. Allergic reactions (dyspnea, cough, rash), which develop in 10% of patients, occur almost exclusively in those receiving either thrombolytic drugs (e. Argatroban has a short half-life (about 45 minutes), owing to rapid metabolism by the liver. Nonetheless, the actions of both products are the same: suppression of coagulation mediated by thrombin and factor Xa. In fact, to protect against thromboembolism, these people typically require lifelong therapy with an anticoagulant, usually warfarin. Treatment consists of a 15-minute loading infusion followed immediately by a continuous maintenance infusion.

While fluid resuscitation and blood transfsions can improve preload and oxygen-carrying capacity cheap 160 mg super avana mastercard, in severe cases ad­ ditional pharmacologic support may be required to improve cardiac contractility and afterload order 160 mg super avana with mastercard. A vasopressor can improve perfsion pressure and maintain blood flow to the tissues purchase super avana 160 mg without a prescription. The Surviving Sepsis Campaign recommends norepinephrine (Levophed) or dopamine at the lowest dose necessary to maintain tissue perfusion. The assessment of the adequacy of tissue perfsion can be determined using blood pressure, Cvo, urine output, normalization of blood2 lactate concentrations, and normalization of base excess on arterial blood gas. Some patients with septic shock do not respond to vasopressors due to relative vasopressin deficiency and would benefit from the addition of vasopressin at a constant infsion rate of 0. Dobutamine is a �-agonist that increases cardiac contractility and therefore increases cardiac output. Dobutamine is given when the Cvo is low2 or when myocardial dysfnction is suspected based on elevated filling pressures or low cardiac output. By increasing cardiac output, oxygen delivery to the tissues may be improved in these individuals. The Role of Glucocorticoid Therapy in Septic Shock Some critically ill patients have a relative adrenal insuficiency and may beneft from glucocorticoid supplementation. The randomized controlled French multi­ center trial involving septic patients with persistent hypotension after appropriate fluid and vasopressor therapy demonstrated improvements in shock reversal and a reduction in mortality when patients received corticosteroids. It is not necessary to prove that a patient has adrenal insuficiency with cortisol stimulation testing prior to giving supplementation. He is tender in the right upper quadrant and has a leukocytosis 3 of 19,000/mm • Which of the following is the best next step in his treatment? Which ofthe following is the most appropriate set of therapeutic endpoint in the treatment of sepsis? Central venous oxygen >70%, urine output > 10 mL/kg/h, central venous pressure 8 to 12 mm Hg D. Additionally his clinical presen­ tation is consistent with infectious cholangitis. Early goal-directed therapy with thegoal of restoring tissue oxygen delivery improves survival from sepsis, so thefirst step in the treatment of this patient should be fluid resuscitation. Diagnosing the source of his infection should be done as well but a right upper quadrant ultrasound is not the initial step in his treatment. The goals of therapy for early goal-directed treatment of sepsis refect the need to restore oxygen delivery to the tissues. Temperature is not an endpoint used to measure the adequacy of tissue oxygenation. Normal central venous oxygen saturation ( >70%) similarly implies adequate oxygen delivery to the end organs. In septic patients, institution ofearly antibiotic therapy, within 1 hour ofdiag­ nosis, is very important. While cultures should be obtained, it is not necessary to prove that infection exists or to identif the infecting organism before start­ ing therapy. It is better to start broad-spectrum antimicrobials initially and then tailor them when culture data is available or stop them entirely if no source is identifed. Surviving Sepsis Campaign: International guidelines for man­ agement of severe sepsis and septic shock: 2008. He was diagnosed with pneumonia confrmed by chest x-ray, and his laboratory tests identifed neutropenia. He received cyclosporine to prevent rejection of his graf, and he is no longer dependent on hemodialysis since his transplant. Blood, urine, and sputum specimens were taken fo r Gram stain, routine culture, acid fa st stain and culture, fu ngus smears and cultures, and cytol­ ogy. Despite the empiricantimicrobial therapy, he continues to appear ill and has a tem perature of l01. Adjust antimicrobials based on culture reports and clinical response (improvement or lack of improvement). To know the immune dysfnction in sepsis and the proinfammatory and anti­ infammatory states. To know the potential methods for monitoring the immune status of a critically ill patient. The patient is immunosuppressed to assist survival of his renal transplantation, and his persistent neutropenia is due to his therapy (cyclosporine). His antibiotic regimen should also be reassessed and possibly changed to cover the earlier-noted bacterial organisms, realizing the possibility of treatment failure with the vancomycin, ceftazidime, and levofoxacin. This resistance is usually plasmid mediated (eg, Klebsiella pneu­ moniae, Pseudomonas aeruginosa, Escherichia coli, Enterobacter sp. Therapy-induced immunosuppression may be caused by a variety of drugs and treatments. These include corticosteroids, azathioprine, methotrexate, mycophe­ nolate mofetil, cyclophosphamide, infiximab, rituximab, an increasing number of chemotherapeutic agents, and irradiation or radiation therapy, to list a few. These infections may arise from microorganisms called "opportunistic infections" (01) that do not normally cause infectious diseases. Infections are usually more severe in immunosuppressed patients, and have a greater potential to result fatally. The best methods to pro­ tect these patients are to avoid unnecessary or overly aggressive immunosuppressive therapy as much as possible, avoid exposure to infectious agents, and reconstitute the immune system when possible. Other preventive strategies include appropriate immunizations, prophylactic antimicrobials, and following isolation and handwash­ ing policies. Travel and immigration has fu rthercomplicated this venuewith the "globalization of infections. Attention to hand washing and the proper use of gloves, facial masks, and clothing is essential. The proper application of hand hygiene is critical in the prevention of these infections, but compliance among health-care workers is below 40%. Health-care associated infections are the most common adverse events resulting from hospitalization. Approximately 5% to 10% of hospi­ talized patients in the developed world acquire such infections. An immunocompromised host may have alterations in phagocytic, cellular, or humoral immunity that increase the risk of infectious complications or provide an opportunistic process from a therapy-induced lympho­ proliferative disorder or cancer. Additionally, patients may also become immunocompromised if they have an alteration or breach of their skin or mucosal defense barriers that permits microor­ ganisms to initiate a local or a systemic infection (eg, indwelling vascular catheters, Foley catheters, endotracheal tubes, and erosions of the mucosa or skin). Specific organisms must be considered in the setting of immunosuppression based on the type of defect(s) present. Specic Organisms Although the causes of fever in immunocompromised hosts are numerous and often never elucidated, some guidance to therapy is given by knowing the specific immunologic defect or defects present in the patient (Table 20-2). The duration of immune defense alteration has an extremely important effect on the types of infectious complications that are likely to occur. The number of septic patients is increasing every year, and the mortality rate from sepsis remains high. Clinically, sepsis initially presents as a hyperinflammatory response to the immune system to attenuate the inflammation, and then progresses to an im­ mune system down-regulation, which can result in prolonged immune dysfnction.

Investigations • Full blood count order super avana toronto, platelet count buy cheap super avana 160mg line, clotting profle • Blood flm to rule leukaemia • All the above clotting factors if indicated order cheap super avana on-line. It causes endometrial atrophy and decreases endometrial prostaglandins and fbrinolysis. Oral progestogens 5 mg three times daily from day 5 to 26 of the cycle cyclically can be given. It can also be used 221 back-to-back for 3 months to build up the haemoglobin levels. Tey are also used as second-line therapy for treatment of inherited bleeding disorder not responding to the other treatments or when these treatments are contraindicated. It is mainly efective in women with type 1 Von Willebrand disease and mild to moderate haemophilia. It is important to give a test dose prior to treatment in order to identify responders from non-responders. It is used as intranasal spray or administered by subcutaneous injection in women with Von Willebrand disease. It is defned as regular heavy menstrual bleeding without any postcoital or intermenstrual bleeding or any palpable pelvic pathology and should have a normal cervical smear result. However, if pipelle is not possible in the clinic a hysteroscopy and endometrial biopsy should be performed. It is also indicated if the ultrasound scan is suggestive of uterine polyps of submucous fbroids. Its use for the whole month may increase the risk of thromboembolism, about which the patient should be warned. Endometrial ablation • Mostly used in older women who have completed their family. Tese signs are seen in women with androgen-producing ovarian (Sertoli–Leydig cell tumours or arrhenoblastoma) or adrenal tumours (adrenal adenoma). Its use is limited to short-term therapy and long-term therapy would need add back therapy with oestrogens in view of its side efects (menopausal symptoms and osteoporosis). Terefore, its use should be limited to patients with severe forms of hyperandrogenemia (e. It antagonizes androgen receptor and has weak progestational and glucocorticoid activity. It suppresses actions of both testosterone and its metabolite dihydrotestosterone on tissues by blocking androgen receptors. The pharmacological actions of this drug are mainly attributed to the acetate form (cyproterone acetate has three times the anti-androgenic activity of cyproterone). Side efects include mastalgia, weight gain and fuid retention causing oedema and fatigue e. In high doses (200–300 mg/day) it can cause liver toxicity; hence liver enzymes should be monitored. However, low doses (2 mg) used in gynaecology are unlikely to cause any major problem. It inhibits 5-alpha reductase activity and therefore blocks the conversion of testosterone to dihydrotestosterone. However, it should be used with caution with a male fetus as it can cause demasculinization. The side efects include liver dysfunction and therefore liver enzymes should be monitored during its use. It has a variable efect on the ovaries and adrenals: it mainly reduces androstenedione. Tese include laser, electrolysis (permanent treatments), chemical depilatories, bleaching, waxing, tweezing, and mechanical epilators (temporary treatments). Antibiotic regimens are designed to cover chlamydia and gonorrhoea as well as anaerobes, gram-negative aerobes and streptococci. Other associated symptoms include vaginal discharge, fever, loss of appetite, vomiting, urethritis, proctitis and intermenstrual bleeding (abnormal uterine bleeding is seen in one third of patients).

Risk reducing measures (bilateral prophylactic 233 mastectomy and breast reconstruction) will reduce this risk to <5%. It therefore increases the overall risk of endometrial hyperplasia and endometrial cancer. If there is any disruption of the pathway, the metabolism is afected and increases the serum oestrogen levels) 26C: False – Induction of ovulation with clomiphene does not increase the risk of endometrial cancer. However, when it is used for more than 12 cycles it has possibly shown to increase the risk of ovarian cancer (limited evidence). Tamoxifen is an oestrogen antagonist on breast and oestrogen agonist on the endometrium. It is used for pre-menopausal women in the treatment of breast cancer when the tumour is oestrogen-receptor positive. This is generally advised for 5 years and has been shown to reduce the risk of recurrence of breast cancer by 50%. However, because of its agonist action on the endometrium, it can cause endometrial hyperplasia and subsequently endometrial cancer. It therefore increases the risk of colon cancer and also increases the risk of endometrial, ovarian and stomach cancer. Afer menopause there is a greater decline in estradiol levels, higher androgen- to-oestrogen ratio, and oestrogen is mainly produced in adipose tissue by aromatization of androstenedione and testosterone. It compares a person’s bone 236 density with the bone density of a young healthy adult or an adult of one’s own age, gender and ethnicity. The difference between a person’s measurement and that of a young adult is known as the T score, and the difference between the same person’s measurement and that of someone of the same age is known as the Z score. Both options can be discussed with the patient and it should be an informed choice. Menopausal status (use 3 for postmenopausal women and 1 for premenopausal women) 3. Simple 239 hyperplasia with atypia has 8% risk of endometrial malignancy and can be treated with high-dose progestogens. Question 2 With regard to contraception and breastfeeding, which one of the following statements is true? Lactational amenorrhoea method is >98% efective in women who are fully breastfeeding within the frst 6 months. Missed pill is defned as one that is more than 12 hours late from the time it should have been taken. Cannot be used to treat endometriosis Question 6 With regard to progestogen-only implants, which one of the following is true? Question 8 With respect to recurrent miscarriages, which one of the following is true? Women with recurrent miscarriages should be screened routinely for thyroid antibodies. Antiphospholipid syndrome is the most important treatable cause of recurrent miscarriages.

By weight discount super avana online american express, 37% of amiodarone is made up of iodine buy genuine super avana online, and this medication is structurally similar to thyroxine order super avana 160mg online. Long-term and short-term adminis­ tration of amiodarone have the potential of producing thyrotoxicosis. This problem is treated with antithyroid medications such as methimazole or propylthiouracil. Interestingly, amiodarone can also cause hypothyroidism; however, the mecha­ nisms that cause amiodarone-induced hypothyroidism are undetermined at this time. Women and those with a history of Hashimoto thyroiditis are at increased risk for amiodarone-induced hypothyroidism. Most cases of hypothyroidism are mild and can be managed with thyroxine replacement or the discontinuation of amiodarone. Proceed with a cosyntropin stimulation test and give hydrocortisone if the patient is demonstrated to have insuficient adrenal response. Strict glucose control targeting glucose levels of 80 to 110 is strongly rec­ ommended for postoperative patients. Glucose control targeting glucose levels of 140 to 180 is associated with lower morbidity and mortality than glucose target levels of 80 to 110. Hyperglycemia is generally not a problem unless individuals are receiving total parenteral nutrition. Serum glucose levels >180 is associated with improved neurological out­ comes following head injury. This patient has persistent septic shock despite suficient fuid resuscita­ tion to restore intravascular volume. Based on the meta-analysis findings of 6 randomized control trial and the American College of Critical Care Medi­ cine consensus recommendations, hydrocortisone should be considered in this individual. Thyroxine replacement and blood transfsions do not play a role in the treatment of vasopressor-refractory septic shock. Measurement ofserum vasopressin levels does not play a significant role in clinical decision-making in this setting. The condition may or may not be the result of amiodarone-induced hyperthy­ roidism. In either case, the appropriate treatment is antithyroid medications such as propylthiouracil. Amiodarone can also produce yperthyroidism byh causing an autoimmune thyroiditis; however, this process generally takes more than 12hours to appear. Current evidence suggest that glycemic control targeting glucose levels of 140 to 180 mg/dL rather than 80 to 110 mg/dL is associated with fewer occur­ rences of hypoglycemia-associated complications. Efect of treatment with low doses of hydrocortisone and fludrocortisones on mortality in patients with septic shock. Treating nonthyroidal illness syndrome in the criti­ cally ill patients: still a matter of controversy. Recommendations for the diagnosis and management ofcor­ ticosteroid insuficiency in critically ill adult patients: consensus statements from an interational task force by the American College of Critical Care Medicine. The fetal heart tones are in the 135 beatsjminute range with occasional variable decelerations on external fetal monitoring. Duringyourexamination, you notice that shehas some fa cial twitching and now is undergoing a tonic-clonic seizure involving both upper and lower extremities. The fetal heart tones are in the 135 beats/minute range with occasional variable decelerations without contractions. During your examination, you notice that she has some facial twitching, and now she is undergoing a tonic-clonic seizure involving both upper and lower extremities. Fetal bradycardia and/or decelerations in heart rate can occur during the seizure episode. Co nsidertions This 18-year-old pregnantpatientpresented with hypertension with a blood pressure of 180/105 mm Hg, headache, and photophobia, all of which are concerning for severe preeclampsia. Because she proceeds with a generalized tonic-clinic seizure, she now has progressed to eclampsia, which appreciably increases the risk to both the mother and the fetus. Con­ sidering she just had a generalized tonic-clonic seizure, she is likely to become motionless and confsed due to the post-ictal state that follows seizures. Because eclamptic patients can become combative after a seizure or they may have another seizure, the railings of her bed should be raised and padding placed on the head board and rails. A padded tongue blade may be carefully inserted into her mouth to prevent biting the tongue, but should not cause a gag reflex or injure the teeth. Her vital signs should be frequently assessed, as well as urine output, proteinuria, and peripheral edema. Treatment includes a loading dose of 6 g of magnesium sulfate over 15 minutes, followed by 2 to 3 g administered continuously. Because convulsions often continue during labor and delivery, as well as post­ partum, the magnesium should be continued for 24 hours postpartum. In the event of status epilepticus that is resistant to magnesium sulfate, she should be intubated and deeply sedated. Once the mother is stabilized, vaginal delivery is initially pursued to avoid maternal risks from cesarean delivery. The fetus is at risk of intrauterine growth retardation and adverse fetal events, so regular surveillance is used for carefl monitoring. These 3 complications contribute greatly to maternal morbidity and mortality rates with hypertensive disorders complicating 5% to 10% of all preg­ nancies. Hypertensive disorders are the most dangerous and deadly complica­ tions of pregnancy. In the Western world, eclampsia ranges from 1 in 2000 to 1 in 3448 pregnancies and is higher in tertiary referral centers, in multifetal gestation, and in patients with no prenatal care. The onset of eclamptic convulsions in the antepartum period range from 38% to 53%, in the intrapartum period between 18% and 36%, and in the postpartum period from 11% to 44%. Pathophysiology The definitive pathophysiology of eclampsia is unknown but several investiga­ tions have implicated the placenta as the main cause. Likely, placental hypoper­ fusion secondary to abnormal modeling of the maternal-fetal interface is the key. Additionally, other factors such as materal vasculature increased sensitivity to pressor agents lead to vasospasm (organ hypoperfsion) and capillary leakage (edema). Though most patients remain asymptomatic, a myriad of com­ plications may exist and involve multiple individual organ systems. Hypertension causes increased cardiac afterload, and the endothelium is injured with extravasation of intravascular fluid, leading to cardiac abnormalities, hemoconcentration, nonde­ pendent edema, and possible pulmonary edema. Complications of the baby include fetal growth restriction from uteroplacental perfsion deficiency caused by defects in trophoblastic invasion and placentation.
