Anaesthesia and intensive care

Propofol formulated in a lipid vehicle supports the growth of microorganisms. There have been worldwide reports of extrinsic microbial contamination of propofol leading to outbreaks of serious postoperative nosocomial infections. Therefore it is essential that medical professionals follow strict aseptic precautions when handling propofol, as recommended by manufacturers of propofol and the Centers for Disease Control and Prevention. ⋯ In vitro studies have confirmed that EDTA added to propofol retards microbial growth. Data on the incidence of nosocomial infections before and after the introduction of propofol with EDTA indicates that there have been no further cluster outbreaks and individual nosocomial infections appear to have been reduced. The addition of EDTA is an additional safety precaution to good aseptic practice.

Randomized Controlled Trial Comparative StudyRecovery after prolonged anaesthesia for acoustic neuroma surgery: desflurane versus isoflurane.
In this study, 33 patients were randomly assigned to receive desflurane (D) or isoflurane (I) for acoustic neuroma surgery. The time from end of the procedure to spontaneous breathing, extubation, eye-opening, hand-squeezing to command, and ability to state name, birthdate and phone number were recorded. The Steward recovery score was also recorded every five minutes during the first 20 minutes postoperatively and then every 10 to 15 minutes. ⋯ Steward recovery scores were also better during the first postoperative hour in the D group (D: 40 min vs I: 90 min, P<0.005 for 100% of patients with Steward score of 6). The results indicate that desflurane is associated with similar operating conditions and faster postoperative recovery following acoustic neuroma surgery. The faster recovery following desflurane may be desirable after long surgical procedures, enabling the patient's full cooperation and facilitating early diagnosis of any potential neurological deficit.
