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.

Aneurysm of the descending thoracic or thoracoabdominal aorta was repaired in 12 cases during simple aortic cross-clamping. The regimen for anaesthesia and general monitoring is presented. It includes thoracic epidural analgesia with intravenous general anaesthesia, use of a double-lumen endotracheal tube, continuous registration of ECG, body temperature, urinary output, systemic and pulmonary arterial pressures and central venous pressure, and intermittent measurement of pulmonary capillary wedge pressure (PCWP), cardiac output, blood gases and haemoglobin. Mannitol (25-40 g) is infused prior to aortic cross-clamping, and infusion of sodium nitroprusside and possibly nitroglycerin is begun just before clamping to control left ventricular afterload and preload. Sodium bicarbonate is given to maintain positive base excess. Before declamping, ventilation is increased by 50% and rapid infusion of blood, plasma and crystalloids is begun in order to raise PCWP by 3-5 mmHg. The clamp is gradually released, and small doses of vasopressor may be required to stabilize the circulation. The operation was uncomplicated in 11 cases, but a patient with ruptured aneurysm died of myocardial infarction.

Limitation of secondary insults after severe head injury is a permanent concern during the early phase of head trauma management. The objectives are to maintain mean arterial pressure between 80 and 100 mmHg, to avoid hypoxaemia, and to maintain arterial PCO2 near to 35 mmHg. Volume loading can be necessary to improve arterial pressure, and is carried out with isotonic critalloid (NaCl 9/1000) or colloids, with the exclusion of all hypotonic solutions (Ringer lactate or glucose). The use of catecholamines is reserved for patients with unstable haemodynamics despite an adequate volume loading. The rapid sequence induction is recommended for endotracheal intubation and is followed by continuous analgesia-sedation to keep patient-ventilator dysynchrony, but without compromising haemodynamic objectives. Mannitol is used in case of life-threatening intracranial hypertension. Conversely, specific treatment of intracranial hypertension, especially hypocapnia, is not recommended. Initial diagnostic procedures include cerebral tomodensitometry (TDM). However, TDM may be delayed in case of haemorrhage, which requires a rapid treatment. Intrahospital transport for additional explorations risks secondary insults, and thus requires close monitoring to detect and treat in due time all adverse events. This monitoring includes invasive arterial blood pressure assessment, use of continuous capnography and repeated arterial blood gas measurements. The usefulness of transcranial Doppler for initial management of head-trauma patients needs further evaluation.
