A retrospective review of maternal mortality in the obstetric unit of Bangkok's Ramathibodi Hospital in 1969-82 was conducted. In this 14-year period, there were 72,872 live births and 26 maternal deaths, yielding a maternal mortality rate of 0.4/1000. Direct obstetric causes accounted for 77% of these deaths. The distribution of the 20 direct obstetric deaths was as follws: septic abortion (10 cases), puerperal infection (3 cases), pre-eclampsia (1 case), eclampsia (2 cases), amniotic fluid embolism (3 cases), and placenta percreta with uterine rupture (1 case). Among the 6 deaths attributable to indirect causes, viral hepatitis was responsible for 3, systemic lupus erythematosus was the cause in 2 cases, and cardiac failure occurred in the final case. The maternal mortality rate was 0.8/1000 amond women 19 years of age and below and 0.6/1000 among women 35 years of age and above compared with 0.2/1000 among those 20-34 years of age. Maternal mortality was 0.6/1000 for cesarean section delivery compared with 0.1 for normal delivery. Ongoing statistical analyses of maternal mortality are urged to serve as the basis for preventive measures.

The hemodynamic effects of lumbar epidural anesthesia (LEA) were evaluated in 11 patients with severe preeclampsia. All patients were receiving magnesium sulfate upon entry into the study. Hemodynamic measurements were obtained before and after LEA, at delivery, and 2 hr postpartum. Lumbar epidural anesthesia significantly reduced mean arterial pressure from 121.4 mm Hg to 97.7 mm Hg, without altering cardiac index, pulmonary vascular resistance, central venous pressure (CVP), or pulmonary capillary wedge pressure (PCWP). There was a slight but statistically insignificant decrease in systemic vascular resistance from 1078 to 900.7 dynes X sec X cm-5. Cardiac index and left ventricular stroke work index were elevated in these patients, suggesting hyperdynamic left ventricular function. There was poor correlation between PCWP and CVP in several patients. We conclude that LEA may be used safely in severe preeclamptic patients and that pulmonary arterial catheters may help guide appropriate therapy in preeclamptic patients with cardiac failure or oliguria refractory to modest fluid challenges.

Pre-eclampsia and 'essential' hypertension in pregnancy require to be studied separately. Their haemodynamic characteristics need to be determined and the effects of antihypertensive therapy and blood volume expansion explored. Diuretics should be used in pre-eclampsia only to treat cardiac failure. Hydrallazine may be contraindicated if cardiac failure is imminent. The role of propranolol remains undecided and a controlled trial is required. Studies of the renin-angiotensin system which take into account the various factors that alter renin secretion may prove useful.

22 patients with severe preeclampsia-eclampsia were treated in our Intensive Care Unit from 1972 to 1978. Control of convulsions was achieved by diazepam, diphenylhydantoin and phenobarbital. In 11 comatose patients brain monitoring was carried out by frequent neurological examination and use of computerized x-ray tomography; aspiration of gastric contents was prevented by nasotracheal intubation. Brain oedema therapy included controlled hyperventilation, steroids and mannitol (7 patients). 10 patients with respiratory failure (due to pulmonary oedema, "shock lung" or aspiration pneumonitis) were treated by mechanical ventilation. Diastolic blood pressure above 100 mm Hg was reduced by hydralazine. Diuresis was induced by normalization of hypovolaemia with albumin and plasma expanders. Six patients died (27%); main causes of death included intracerebral haemorrhage, brain oedema, heart failure, acute pulmonary thromboembolism and bleeding from DIC.

Six very preterm (< 32 weeks' gestation) infants who developed late-onset respiratory distress were each matched for sex and gestation with 2 control preterm infants. Radiologically and biochemically the diagnosis of rickets and rachitic respiratory distress seemed clear and the pattern conformed with other reports of the syndrome. The control infants were of similar gastational ages but there was a significantly higher incidence of pre-eclampsia in the pregnancies of index cases. Also significant was a prolonged illness of several weeks' duration in the index cases; this illness was either heart failure due to patent ductus arteriosus or prolonged ventilation in the early weeks of life for apnoeic attacks. Awareness of these 2 aetiological factors shows the necessity of monitoring such infants for evidence of rickets. The use of water-soluble antirachitic prophylaxis such as 1 alpha-hydroxy-vitamin D or 1,25-dihydroxy-vitamin D is sometimes indicated.

Two pregnant patients presented with Takayasu's disease predominating in the major branches of the aorta. There was no extention below the diaphragm and no complications. One of the patients had Still's disease which is a predominantly cutaneous form without chronic arthritis. Both pregnancies were uneventful excepting dysgravidia in one case. Two eutrophic infants were born at term. The risk of Takayasu's arteritis associated with pregnancy, as reported in the literature, is mainly due to the consequences of arterial hypertension with pre-eclampsia (60%), heart failure and cerebral vascular events (5%). The major fetal risk is in utero death (2 to 5%), but intra-uterine growth retardation is more frequent (18%). The risk is greatest during the third trimester and during the perinatal period. Fetal involvement is greatest in sever cases and in those treated late. Prevention is based on the initial work-up to identify the disease and possible complications, programming pregnancies and increasing surveillance during periods of risk, defining the delivery route with cesarean section reserved for complications of arteritis (30%), and planned labour with instrumental extraction and epidural anaesthesia with control of the blood pressure. Still's disease has no particular consequence on pregnancy, although sequellae of chronic arthritis of the pelvis may have an impact on obstetrical technique. An association with Takayasu's disease is rare with only one case being reported in the literature; aetiopathology remains unknown.

A case of a pregnant woman who underwent urgent cesarean section is presented. The patient had severe hyperthyroidism, preeclampsia, and congestive heart failure, which had not been treated until 36 weeks of gestational age. At 38 weeks, fetal distress occurred and an urgent cesarean section was performed successfully under epidural anesthesia with preoperative treatments using iodide, hydrocortisone and propylthiouracil. The patient required postoperative intensive care for heart failure. Thyroid function of the neonate was almost normal. No abnormality was observed except low birth weight.

Twelve Caesarean section-associated maternal deaths were encountered over a 15-year period. The major operative risk factors were pregnancy-induced hypertension, obesity and general anaesthesia. Severe preeclampsia was the forerunner to postoperative cardiac failure, consumptive coagulopathy and difficult airway manipulation. We conclude that pregnancy-induced hypertension and its ramifications pose the greatest threat to maternal survival from a Caesarean section.

We describe a case of Cushing's syndrome complicating pregnancy presented with acute heart failure, hypertension and glucose intolerance. A left adrenal adenoma was removed at 24 weeks of gestation. The pregnancy was ended with an emergency lower-segment Caesarean section at 31 weeks of gestation because of severe pre-eclampsia and HELLP syndrome. The case is reported not only because of its rarity but also to induce the discussion of surgical treatment during pregnancy.

The aim of this study is to review the recent developments in research on the pathophysiological role of endothelins in the reproductive system and lungs, as well as in systemic disorders such as sepsis, acute respiratory distress syndrome and multiple organ failure. The international literature of the last 9 years, as available on MEDLINE, was duly scanned. Only relevant, original and update studies were selected for the purpose of this survey. The results of the most significant studies in humans are summarized. The potential roles of endothelins in systemic diseases are currently under investigation. A possible role of these peptides is suggested in the pathophysiology of heart failure and in the mechanism of post-ischemic renal failure. Studies have been conducted also on other systems, namely the reproductive system, the endocrine system and the lungs as well as on a number of tissue disorders such as sepsis, acute respiratory distress syndrome multiple organ failure, preeclampsia and related abnormalities. Full understanding of the role and action of this group of regulatory mediators in tissues should enable complete insight into the pathophysiological mechanisms of localized diseases as well as of multiple organ diseases. As a result, adequate therapy may be established.
