A male patient with pycnodysostosis suffered from chronic respiratory insufficiency and pulmonary hypertension. This was caused by concomitant upper airway obstruction, resulting from a low implanted uvula and a long soft palate, in combination with glossoptosis and retrognathia due to the flattened mandibular angles. An inter-current respiratory infection gave rise to an acute deterioration, with right-sided heart failure, severe liver damage and coma. Surgical shortening of the soft palate was performed, after which the blood gas values returned to normal.

A 64-year-old man developed severe hyperbilirubinemia of predominantly conjugated fraction in 1978, eight years after a myocardial infarction and development of congestive heart failure. In 1975, he was admitted elsewhere for symptoms suggestive of chronic hepatitis, but liver biopsy revealed replacement of hepatocytes by red blood cells which was interpreted as a result of left-sided cardiac failure. In 1978, liver biopsy showed congestive liver disease with cardiac sclerosis. Despite initial improvement, his condition deteriorated, he became encephalopathic, and died in a coma. This case is reported to illustrate that chronic congestive heart failure can present with severe jaundice and terminate in hepatic coma.

Haemodynamic effects of suxamethonium IV 1 mg/kg were studied in eight comatose, mechanicaly ventilated, normotensive patients. Drug interference, including atropine was avoid. A transitory but significant increase in heart rate and cardiac output (CO) was observed, respectively + 27 p. cent (p less than 0.02) and + 29 p. cent (p less than 0.025) at the first minute. Right auricular, pulmonary capillary wedge, and pulmonary arterial pressures increased significantly from the first to the eighth minute. Mean arterial blood pressure unsignificantly increased (+ 5 p. cent) wether systemic arterial resistance decreased from - 11 p. cent (p less than 0.02) at the first minute. No arrhythmia occurred throughout the study. In the conditions of this study suxamethonium induces an early and transient increase in CO. Both tachycardia and increased venous return can explain the rise in CO. Such an increase could be due to the transient abdominal hyperpressure, and can be one of the factors which explain the poor tolerance of suxamethonium in patients with heart failure.

Among the 94 tricyclic antidepressant intoxications received in 3 years in the intensive care unit of Edouard Herriot Hospital, 16 with cardio-vascular manifestations are studied. The criteria of selection is the presence on the electrocardiogram (ECG) of a ventricular trouble in conduction excitability or automaticity. Eight times, the ingested dose exceeds 20 mg/kg. 10 times several toxics are taken explaining the severity of coma and the rarity of convulsions. 2 collapses, 1 shock, 1 cardiac arrest occur. The most frequent ECG abnormalities are: T modifications, (90 p. 100), prolongation of QT interval (60 p. 100), right bundle branch block (50 p. 100) or left one (25 p. 100). Only one death occurs; (1 p. 100 of this series). Ventricular dysrythmia or myocardial failure represent the main criteria in the evaluation of severity of the tricyclic antidepressant intoxication. For the treatment, a complete digestive evacuation is needed, Hemodialysis, plasmapheresis, or hemoperfusion cannot be actually recommended. The treatment of cardiac troubles involves essentially sodium. and eventually intra-cardiac pace maker.

Eight patients with proven tick-borne encephalitis (early-summer meningo-encephalitis; central European encephalitis) were treated in 1979. The disease ran a severe course in four: one died after six weeks of coma and pneumonia with right-heart failure. Another patient is in coma for more than 40 weeks. A third patient had severe flaccid tetraplegia more than 10 weeks after initial coma. The fourth patient still had leg paresis after nine weeks, her left arm also being largely paralysed. This high incidence of severe forms of the disease differs from other published reports.

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.

Recent advance in vascular surgery have made vascular reconstruction of the carotid artery possible. Since 1990, the authors have performed en bloc resection of the carotid artery and vascular reconstruction of the carotid artery, using a temporary shunt tube, in 10 cases. Among these 10 cases of tumors involving the carotid artery, two cases had carotid body tumors and the other eight cases had metastatic lymph nodes from head and neck cancers. Transient motor paralysis occurred in three cases and disorientation in one after the operation. None has developed severe neurological complications such as death, coma or permanent hemiplegia. Despite preoperative irradiation, local infection was noted in only one case after the operation. Rupture of the vein graft was prevented by using a DP flap to cover dead space at the anastomotic site. The two patients with a carotid body tumor are alive without evidence of recurrence. Among eight patients with cancer, three are still alive and disease free (respectively 44, 30 and 16 months). Two patients died of local recurrence, two of distant metastasis and the other of acute heart failure. Local tumor control was possible in six out of eight patients. We were able to safely perform en bloc resection of the carotid artery and vascular reconstruction of the carotid artery using a temporary shunt tube. In conclusion, we anticipate increasing curability of advanced tumors involving the carotid artery using this procedure.

Our aim was to assess clinically whether there was any benefit in adding a single dose of sublingual nifedipine (a slow calcium channel blocker) to prazosin in the management of the cardiovascular manifestations of envenoming by the Indian red scorpion (Mesobuthus tamulus). A total of 163 patients stung by this species was admitted to hospital at Mahad between January 1991 and October 1993. Cardiovascular abnormalities were hypertension (59), of whom 42 had bradycardia and 17 had tachycardia; pulmonary oedema (14), of whom eight had hypertension and six hypotension; supraventricular tachycardia (eight), of whom three had hypotension and one died. Of the remaining patients, 78 demonstrated severe excruciating local pain at the site of sting but had no systemic involvement. Nineteen patients with hypertension and tachycardia were given a single dose of sublingual nifedipine plus prazosin on admission, then prazosin alone repeated 6 hourly. Five patients with massive life-threatening pulmonary oedema recovered after being given intravenous sodium nitroprusside. Prazosin alone helped to alleviate cardiovascular manifestations in the remaining 52 victims. One patient was admitted in a deep coma, 12 hr after the sting, and died. Eight victims whose blood pressure had been controlled in hospital by nifedipine plus prazosin developed acute pulmonary oedema necessitating additional doses of prazosin for recovery. Fifty-two victims treated with prazosin alone did not develop pulmonary oedema and the drug appeared to hasten the recovery. In the presence of high blood pressure, tachycardia, a murmur and impending myocardial failure, nifedipine appeared to contribute to cardiopulmonary instability and to augment myocardial oxygen consumption. In this situation calcium channel blockers should probably be avoided.

Iron poisoning is the most common cause of overdose mortality in children under six years of age and there are no reports of survival with iron levels > 2687 mumol/L (> 15,000 micrograms/dL). A 22-month-old male was brought to the emergency department by his parents after ingesting an estimated 50 ferrous sulfate tablets (60 mg elemental iron/tablet) several hours earlier. Despite spontaneous emesis and gastric lavage his condition deteriorated and he was found to have a serum iron of 2992 mumol/L (16,706 micrograms/dL). During the first four days in the intensive care unit, he developed coma, metabolic acidosis, hypovolemic and cardiogenic shock, liver failure, coagulopathy and adult respiratory distress syndrome. He was treated with a unique deferoxamine dosage schedule (25 mg/kg/h for 12 h/d x 3 d), mechanical ventilation, Swan-Ganz catheter monitoring, dopamine/nitroprusside therapy, blood product, bicarbonate, electrolyte and volume replacement. After a prolonged hospital course complicated primarily by gastric outlet obstruction he was dismissed on full oral feedings, gaining weight, and neurologically intact. Swan-Ganz catheter monitoring guided the management of this patient's shock, iron-induced cardiac failure, and deferoxamine mesylate induced adult respiratory distress syndrome. Further experience and research is required to determine the most appropriate deferoxamine mesylate dosing schedule and our experience expands the range for possible survival after massive iron overdose.

Continuous retrograde hypothermic low flow cerebral perfusion (CRCP) with deep hypothermic systemic circulatory arrest (DHSCA) during aortic arch surgery was employed in six patients, aged 21-79 years. From August 1991 to November 1992, five of these patients were operated for ascending and arch aortic dissection type I, and one patient was operated for an aneurysm extending from the ascending aorta into the arch. Cardiopulmonary bypass (CPB) technology included a centrifugal pump and low-dose aprotinin. Venous drainage was established via the superior and inferior caval veins and arterial return via the femoral artery. Prior to CPB, a bypass line connecting the arterial line with the superior vena cava cannula was implemented. Prior to DHSCA, the patients were systemically cooled to a mean nasopharyngeal temperature of 15.2 degrees C. After induction of systemic circulatory arrest, the femoral artery cannula was clamped. Thereafter, the implemented bypass line was opened to achieve reverse flow into the superior vena cava to allow venoarterial perfusion. The perfusate was returned to the CPB circuit through drainage from the inferior caval vein and by aspiration of blood from the opened aortic arch. CRCP flow rate ranged from 250 to 450 ml/min (mean 375 ml/min) maintaining an internal jugular vein pressure between 18 and 25 mmHg. The duration of CRCP ranged from 24 to 55 minutes (mean 39 minutes). Postoperatively, one patient died of cardiac failure. The other five patients regained full consciousness without neurological deficits, as defined by the Glasgow coma score, within 48 hours after the operation. Neither did we see other major organ complications.(ABSTRACT TRUNCATED AT 250 WORDS)
