With improving standards of antenatal care, severe pre-eclampsia dn eclampsia are becoming less common and experience in the management of these conditions is lessening. Co-ordinated plans for the care of patients should be established by obstetricians and anaesthetists working as a team. A suitable regime for drug therapy in severe pre-eclampsia or eclampsia is the following: Initial management Diazepam 10 mg slowly i.v. Pethidine 100-150 mg i.m. or i.v. in incremental dosage, or extradural blocks, if analgesia is also required. Hydrallazine 20 mg i.v. initially, followed by 5 mg at intervals of 20 min until the diastolic pressure is less than 110 mm Hg. Then, preferably by syringe pump in a concentration of 2 mg/ml, at a rate of 2-20 mg/h. If vomiting occurs this can be controlled by administration of atropine. Subsequent management Sedation and anticonvulsant therapy. Continue diazepam and, in severe cases, institute chlormethiazole infusion. Continue analgesia with pethidine or extradural block. Control of hypertension by adjusting the dose of hydrallazine. If tachycardia exceeds 120 beat/min give propanolol 2-4 mg i.v. Plasma protein depletion with groww oedema is treated by administration of salt-free albumin or plasma protein fraction. Diuretic therapy is indicated if there is gross oedema or signs suggestive of acute renal failure. Oliguria associated with increased blood urea may be a result of renal failure or dehydration. The latter should be evident from the patient's condition and central venous pressure, but i.v. fluids and frusemide 20-40 mg can be used as a therapeutic test. Mannitol reduces cerebral oedema and may be given if diuresis has been first produced with frusemide. Potassium chloride is given if the plasma potassium decreases to less than 3 mmol/litre. Heparin therapy is considered if there is clinical evidence of disseminated intravascular coagulation.

The efficacy of fixed dose PGE2 (prostaglandin E2) in inducing labor was studied in 40 multiparous patients. Low amniotomy was performed, and 1 tablet of 6.5 mg PGE2 was given orally in the absence of uterine activity after 30 minutes, and hourly thereafter until the patient delivered. Successful induction was defined as the establishment of effective uterine contractions and cervical dilatation within 12 hours of amniotomy. Indications for induction are postmaturity (n=15); pre-eclampsia (n=10); essential hypertension (n=6); weight loss (n=4); bad obstetric history (n=2); and others (n=3). 38 patients (95 percent) had successful labor induction, with 37 delivering vaginally within 18 hours of amniotomy and 1 delivering by Cesarian section because of fetal distress. In the remaining 2 patients, labor did not commence within 12 hours and consequently necessitated intravenous oxytocin. Mean amniotomy-delivery interval was 7.53 hours. Maternal side effects included vomiting (12.5%); diarrhea (5%); pyrexia (15%); ketonuria (22.5%); and postpartum hemorrhage (12.5%). There were no apparent fetal side effects. Advantages of oral PGE2 for labor induction include: 1) ease of administration; 2) increased patient acceptability; 3) greater convenience for medical and nursing staff; 4) absence of complications associated with intravenous infusion such as sudden changes in infusion rate, air emboli or occasional pyrogen reactions. Advantages of using a low fixed dose are: 1) excessive administration and subsequent uterine hypertonus are less likely to occur; 2) low incidence of vomiting/diarrhea; and 3) absence of uterine hypertonus and apparent fetal side effects.

Neither the cause nor the effect of severe vomiting during pregnancy is well understood. This study examines possible causes of severe vomiting and associations between this disorder and fetal outcomes. One thousand eight hundred sixty-seven women with normal singleton live births were included in the analysis. The cumulative incidence of severe vomiting during pregnancy was 10.8%. Women with chronic liver disease had a threefold increased risk of severe vomiting during pregnancy. Paternal smoking was associated with a twofold increased risk of maternal vomiting. A modest association between severe vomiting and fetal growth retardation was identified (OR = 1.4, 95% CI: 0.9-2.3). Severe vomiting was also found to be associated with preeclampsia (OR = 1.5, 95% CI: 1.0-2.4). Our study indicates that passive smoking is a risk factor for vomiting during pregnancy, which may, in turn, increase the risk of fetal growth retardation.

The syndrome of haemolysis, elevated liver enzymes and low platelets (HELLP Syndrome) is a consequence of severe preeclampsia/eclampsia. The clinical course is characterized by an unusual presentation with abdominal pain, and manifestations of inadequate haemostasis and excessive bleeding are common. Maternal and perinatal morbidity and mortality are high. We report our experience with 33 patients over a five-year period. The mean gestational age (GA) of the pregnancies was 34 +/- 2.8 wk including 11 patients who delivered 12 neonates of less than 34 wk GA. The most common presenting complaints were right upper quadrant or epigastric pain in 25 patients (76%) and nausea or vomiting in 14 patients (42%). Diagnosis was missed or delayed in 12 patients (36%). Thirty-one patients (94%) were delivered by Caesarean section and a deteriorating maternal condition was the most common indication for operative delivery. Twenty-three patients received general anaesthesia, eight received epidural anaesthesia and there were no complications related to the anaesthetic. There was clinical evidence of abnormal haemostasis: seven patients had excessive blood loss at Caesarean section, two had postpartum haemorrhage, three developed DIC and four developed wound haematoma. The average decrease in haemoglobin concentration was 32 g.L-1 and twelve patients (36%) received blood transfusions. There was one stillbirth. There were no neonatal deaths but morbidity was prominent and related primarily to prematurity. Delayed or missed diagnosis is common in HELLP syndrome and a premature delivery by Caesarean section is usual.(ABSTRACT TRUNCATED AT 250 WORDS)

The question of whether the HELLP syndrome exists as a distinct entity or is part of a spectrum of pregnancy complications, which have in common hemolysis, elevated liver enzymes, and thrombocytopenia, has long been a source of speculation and debate among obstetricians and internists. A review of the literature indicates a definite need for a uniform definition, diagnosis, and management of this syndrome. Patients manifesting this syndrome usually are seen before term (less than 36 weeks' gestation) complaining of malaise (90%), epigastric or right upper-quadrant pain (90%), and nausea or vomiting (50%), and some will have nonspecific viral-syndrome-like symptoms. Hypertension and proteinuria may be absent or slight. Thus some of these patients may have a variety of signs and symptoms, none of which are diagnostic of classic preeclampsia. In consideration of the high maternal and perinatal mortality and morbidity reported with the presence of this syndrome, I recommend that all pregnant women having any of these symptoms should have a complete blood cell count with platelet and liver enzyme determinations irrespective of maternal blood pressure.

Characteristic features of expert evaluation of temporary disability during pregnancy and after abortion and labor adopted in the USSR are outlined. At the earliest stages of pregnancy, women should be assigned to the work not associated with potential exposure to hazardous factors. Women with pregnancy complications should undergo comprehensive examination, preferably in a hospital setting: average length of stay is 20 days for threatened abortion, 21 days for premature labor (28-37-week pregnancy), 16 days for hypertension, 14 days for vomiting or nephropathy, 17 days for anemia, and 14 days for Rhesus-incompatibility. After abortion on demand or abortion for medical indications, a woman should be given a sick leave. The length of sick leave depends upon the pregnancy term (56 days for pregnancy longer than 28 weeks). Women with normal pregnancy and labor can receive a leave for 112 calendar days (56 days during the prelabor period and 56 days for the postpartum period). In the case of labor complications or multiple pregnancy, duration of the postpartum leave should be increased to 70 days. Indications for a 70-day postpartum leave include preeclampsia or eclampsia; cesarean section or vacuum-extraction; profuse hemorrhage during labor requiring blood transfusions; tears of the cervix uteri; postpartum endometritis, thrombophlebitis, septicemia, and suppurative mastitis; history of heart valve disease or congenital heart defects; and premature labor.

This study reviews liver disease in toxemia of pregnancy based on 102 cases submitted to the Armed Forces Institute of Pathology. The common clinical features were right upper quadrant and epigastric pain, nausea, vomiting, and elevation of the serum transaminases. Jaundice occasionally developed. These occurred in severe preeclampsia or eclampsia and their cause was usually recognized. However, hepatic symptoms and signs did result in inappropriate diagnoses and misdirected therapy. Such confusion occurred when these were the initial problems confronting the clinician in women presenting with advanced toxemia due to poor prenatal care. They were also likely to be misleading when other more classic parameters, such as blood pressure and proteinuria, were only midly abnormal. Central nervous system complications were the common cause of death but liver disease could be partially or wholly responsible. Extensive periportal lesions, hepatic hematomas, spontaneous rupture, and infarction all contributed to hepatic injury and to morbidity. Fibrin deposition, hemorrhage, or both in the periportal areas was characteristic of the histopathology. Scanning electron microscopy validated this spectrum of change. A toxemic vasculopathy related to severe vasospasm in the hepatic arterial circulation may be responsible.

The case of a 32-year-old primigravida, 32 weeks gestation, with nausea, vomiting, thrombocytopenia, and abnormal liver function tests is presented. A diagnosis of severe preeclampsia was made and the patient underwent emergency cesarean section. Improvement of clinical symptoms and laboratory studies followed over the succeeding days. These less common manifestations of preeclampsia indicate severe disease necessitating aggressive management, even in the setting of a normal blood pressure. Thrombocytopenia, microangiopathic hemolytic anemia, or abnormal liver functions in a patient presenting in the latter half of pregnancy may be manifestations of severe preeclampsia.

The perceptive physician can anticipate and prevent eclampsia. If possible, he should try to prolong preeclamptic pregnancies to the 37th week to avoid neonatal deaths from complications and prematurity. In some cases, preeclampsia strikes and progresses rapidly before the 30th week, however, and, in order to save the mother, the pregnancy must be terminated. If the preeclamptic woman deteriorates to the point where severe headache, epigastric pain, vomiting, and hyperreflexia exist, eclampsia is imminent. If she becomes eclamptic, clinicians must immediately begin to manage the convulsions with a sedative. Diazepam has proved successful which accounts for its widespread use in Great Britain and developing countries. Large doses given over a long period of time, however, adversely affect the newborn, e.g. respiratory depression. Another popular sedative is magnesium sulphate (in use for 50 years). Dangers of overdose can be avoided by testing the patella reflex every hour when magnesium sulphate is being administered intravenously: the reflex becomes null before serious toxic effects occur. If the systolic blood pressure exceeds 170mmHg, antihypertensives should also be given selectively to prevent cerebral hemorrhage. The preferred antihypertensive must act rapidly and predictably, with a wide margin of safety between the therapeutic and toxic dose. Hydralazine hydrochloride meets these requirements. Fluid and acid-base balances must be controlled to treat hypovolemia, oliguria, and acidosis. The longer delivery is delayed, the worse the outlook for mother and infant. Regardless of the type of delivery, clinicians must avoid hemorrhage and operative shock because eclamptics cannot tolerate blood loss. It is imperative that clinicians do not become so involved in saving the patient that they overtreat her, e.g., mixing antihypertensives.

Twenty patients with severe postpartum hemorrhage due to uterine atony who were unresponsive to conventional therapy were treated with 0.25-mg intramuscular injections of (15-S)-15-methyl prostaglandin F2 alpha-tromethamine. A rapid and successful response was obtained in 18 patients. Two patients required surgical procedures to control bleeding. Both patients with treatment failure had chorioamnionitis. Side effects of the prostaglandin therapy included nausea, vomiting and diarrhea, a transient mild temperature elevation, and a transient moderate blood pressure elevation. Those subjects with preeclampsia did not demonstrate a serious elevation of blood pressure. The prostaglandin F2 alpha analogue appears to be very effective in the treatment of postpartum hemorrhage due to uterine atony.
