Complications and Morbidity of Controlled Hypotension

Comparative Evaluation of Oral Clonidine and Oral Atenolol as Premedication in Functional Endoscopic Sinus Surgery (FESS) Under General Anaesthesia

“…Even a small amount of blood may disturb the endoscopic view, increasing the likelihood of complications as well as lengthening the operative procedure and possibly resulting in incomplete surgery [7] . The threat of serious complication from the poor visibility due to excessive bleeding in the surgical field and the possibility of neurological damage makes it important for anesthesiologists to produce optimal surgical conditions [8] . Several methods have been designed to reduce bleeding during surgery, none of these techniques have consistently provided a desirable bloodless field for the surgeon.…”

Controlled Hypotension in Hip Joint Surgery:An Assessment of Surgical Haemorrhage During Sodium Nitroprusside Infusion

“…Deliberate hypotension is regarded as safe, as long as the systolic blood pressure is not reduced below 50 mmHg (Slack & Walter 1964). In actual practice, levels of mean arterial blood pressure lower than 60-65 mmHg are not necessary and no undesirable effects have been reported with a combination of careful monitoring and correct positioning of the patient subjected to induced hypotension (Royester et al 1951, Eckenhoff 1955, Tough 1960, Enderby 1961, Linacre 1961, Lindop 1975. Continuous arterial monitoring is a simple procedure and without ill-effects on the patients (Brown et al 1969, Zorab 1969.…”
