Propofol for maintenance of general anesthesia: A technique to limit blood loss during endoscopic sinus surgery

Hypotensive Anesthesia with Propofol Infusion Pump: A Boon for Endoscopic Sinus and Nasal Polyps Surgery

“…Both halothane and propofol produce a decline in systolic blood pressure by a combined effect of depressed cardiac contractility. 4,8 Diminished systemic vascular resistance is seen only with propofol. Factors exacerbating the hypotension include large doses, rapid injection and old age.…”

“…4,8 Propofol is contraindicated in patients with impaired ventricular function who may experience a significant drop in cardiac output owing to decreases in ventricular filling pressures and contractility. 4,8 The blood loss difference between the patients receiving general anesthesia based on continuous infusion of propofol, and the patients receiving the inhalation agent halothane was observed. Total intravenous anesthesia with propofol infusion pump is a new technique for maintenance of general anesthesia and is associated with decreased bleeding during endoscopic sinus surgeries and septorhinoplasty compared with conventional inhalation agent techniques with halothane.…”

“…Factors exacerbating the hypotension include large doses, rapid injection and old age. 4,8 Hence, propofol infusion pump is used to deliver titrated dosed of propofol. 4,8 Propofol is contraindicated in patients with impaired ventricular function who may experience a significant drop in cardiac output owing to decreases in ventricular filling pressures and contractility.…”

Cardiorespiratory Response Model for Pain and Stress Detection during Endoscopic Sinus Surgery under Local Anesthesia

“…In the actual surgery, the existence of pain and stress is generally esti-mated by the blood pressure changes [3], but it is quite difficult to measure patient's beat-to-beat blood pressure without discomfort, and autonomic indices can be change not only by the effect of autonomic activity but also the effect of body movement and/or breathing activity.…”
