Sixty patients premedicated with temazepam were allocated randomly to receive an infusion of propofol designed to achieve and maintain a target blood concentration of 3, 4 or 5 micrograms.ml-1. Induction time was measured from the start of infusion to loss of verbal contact. The success rate of inducing anaesthesia within 3 min of achieving the target(More)
We have studied 20 patients undergoing local resection of intraocular melanoma during hypotensive anaesthesia, allocated randomly to receive either manual control by an experienced anaesthetist or closed-loop computer control of an infusion of a 5:1 mixture of trimetaphan camsylate (TMP) and sodium nitroprusside (SNP). There were no significant differences(More)
BACKGROUND Noninvasive mechanical ventilation (NIMV) is the delivery of positive pressure ventilation through an interface to upper airways without using the invasive airway. Use of NIMV is becoming common with the increasing recognition of its benefits. OBJECTIVES This study was done to evaluate the feasibility and outcome of NIMV in tertiary care(More)
Thirty patients who had undergone coronary artery bypass grafting and who required vasodilator therapy for control of arterial hypertension were allocated to receive either low-dose or high-dose enoximone or placebo infusions. A closed-loop arterial pressure control system was used to assess cardiovascular stability and the amount of sodium nitroprusside(More)
Forty patients who had undergone coronary artery graft surgery and who required vasodilator therapy for postoperative hypertension were given infusions of either propofol (2,6,di-isopropylphenol) or midazolam, together with an infusion of morphine for analgesia while ventilation was controlled artificially. Sodium nitroprusside was administered to patients(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) patients frequently pose difficulty in weaning from invasive mechanical ventilation (MV). Prolonged invasive ventilation brings along various complications. Non-invasive positive pressure ventilation (NIPPV) is proposed to be a useful weaning modality in such cases. OBJECTIVE To evaluate the(More)
