Cerebral Oximetry in General Anaesthesia.

Bispectral index and cerebral oximetry in low-flow and high-flow rate anaesthesia during laparoscopic cholecystectomy – a randomized controlled trial

INTRODUCTION The need to reduce pollution emissions in the operating room and to reduce treatment costs motivates more frequent use of general anaesthesia with a small or minimal fresh gas flow rate. Nevertheless, the reduction of the delivery of fresh gases should not influence the quality and safety of the anaesthesia. MATERIAL AND METHODS A total of 105 elective laparoscopic cholecystectom...

Intravenous phenytoin and percutaneous arterial cannulation: the purple-glove syndrome.

propofol and remifentanil has been reported to be successfully used in a patient with narcolepsy who underwent cardiac surgery [6]. The authors of that report considered that perioperative monitoring of the patient’s hypnotic state would have added valuable information, but this kind of monitor was not available in their department [6]. There are limited data about inhalational anaesthesia in n...

The differing effects of regional and general anaesthesia on cerebral metabolism during carotid endarterectomy.

OBJECTIVES To examine the effects of either regional (RA) or general (GA) anaesthesia upon parameters of cerebral metabolism (near infrared spectroscopy, continuous jugular venous oximetry) during carotid endarterectomy. DESIGN Prospective, non-randomised, observational study. MATERIALS Sixty-five consecutive patients (33 RA; 32 GA) undergoing carotid endarterectomy. METHODS (i) Near infr...

What does cerebral oximetry measure?

Effect of incremental doses of sevoflurane on cerebral pressure autoregulation in humans.

We have examined cerebral pressure autoregulation while awake, and during 0.5 and 1.5 MAC of sevoflurane anaesthesia in 10 patients undergoing non-intracranial neurosurgical procedures. All patients received a standardized anaesthetic comprising premedication with temazepam 20 mg orally, a sleep dose of propofol, fentanyl 1 microgram kg-1 and vecuronium 0.1 mg kg-1. After tracheal intubation, t...
