Perioperative spirometric data following ambulatory anaesthesia in elderly patients: Comparison of desflurane versus sevoflurane anaesthesia

Abstract

22Ambulatory anaesthesia sevoflurane (r2=0.01, p=0.63) group. Multivariate analysis (Stata 9.0), including patient gender, age, MAC hours and opioid administration, revealed that only desflurane correlated positively with faster recovery of AWR (p<0.001). Conclusion(s):These preliminary data suggest that increased body mass index may not be associated with delayed recovery of airway reflexes irrespective of the choice of inhaled anesthetic. AWR recovery remains faster and more predictable after a desflurane anesthetic.Background and Goal of Study: Various anaesthetic techniques can be performed for minor anorectal surgery. Most probably due to psychologic factors, patients tend to prefer general anaesthesia compared to regional techniques. The present study evaluates the practicability, patients' acceptability and postoperative analgetic need for both anaesthetic techniques in patients undergoing minor anorectal surgery. Materials and Methods: 138 ASA I-II patients (m/f, 18-85 years) were randomized to receive either spinal anaesthesia ("SPA", n=69) using 1.0 mL hyperbaric bupivacaine 0.5% or total intravenous anaesthesia ("TIVA", n=69) with propofol and fentanyl using a laryngeal mask. In a questionnaire the patients were asked about postoperative comfort, arising problems, pain and unpleasant perceptions. Results and Discussion: Patients receiving "SPA" had a shorter monitoring time at the recovery room (2±6 min vs. 45±26 min, p<0.001), a later onset of pain (385±210 min vs. 194±319 min, p<0.0001) and were able to tolerate food (161±242 min vs. 226±154 min, p<0.0001) and water (70±67 min vs.
