that the post-operative ventricular tachycardia did not produce hypotension or pulmonary oedema. The operation of aorto-coronary by-pass has been very successful in the treatment of intractable angina, but objective evaluations of its effect on left ventricular function are few. Chatterjee et al. (1972), Gareth Rees et al. (1971), have shown that this operation does produce symptomatic and meas...

The paper reviews mechanisms underlying autonomic disorders, with a focus on cardiovascular dysfunction. Neurosurgical approaches are described for medically refractory hypertension and orthostatic hypotension. After review of microvascular decompression of the rostral ventrolateral medulla, stereotactic CT and MRI guided deep brain stimulation of the periaqueductal grey matter (PAG) is evaluat...

OBJECTIVE To describe main indications, doses, length of infusion and side effects related to dexmedetomidine infusion. METHODS Observational and retrospective study evaluating dexmedetomidine use in pediatric intensive care unit. RESULTS 77 children received dexmedetomidine infusion longer than 6 hours for mechanical ventilation weaning (32.5%), post- neurosurgery and post-upper airway sur...

Diphenhydramine toxicity commonly manifests with antimuscarinic features, including dry mucous membranes, tachycardia, urinary retention, mydriasis, tachycardia, and encephalopathy. Severe toxicity can include seizures and intraventricular conduction delay. We present here a case of a 23-year-old male presenting with recurrent seizures, hypotension and wide complex tachycardia who had worsening...

Poisoning with tricyclic antidepressants is an important cause of drug-related self-poisoning in the developed world and a very common cause of poisoning and mortality in developing countries. Electrocardiographic manifestations of most tricyclic antidepressant-poisoned patients resolve by the administration of 1-2 mEq/kg of sodium bicarbonate. Some rare cases have been reported who have been r...

The management guideline for traumatic brain injury (TBI) recommends high-dose barbiturate therapy to control increased intracranial pressure refractory to other therapeutic options. High-dose barbiturate therapy, however, may cause many severe side effects; the commonly recognized ones include hypotension, immunosuppression, hepatic dysfunction, renal dysfunction, and prolonged decrease of cor...

In a 57-year-old woman who was referred as refractory diastolic heart failure, dobutamine stress echocardiography facilitated the diagnosis of acute worsening of mitral regurgitation accompanied with latent left ventricular outflow tract obstruction as a cause of recurrent flash pulmonary edema. Echocardiography revealed the presence of sigmoid septum and concentric left ventricular hypertrophy...
