Evaluation of patient controlled sedation and analgesia for ESWL.

This study was designed to evaluate the quality of sedation/analgesia and patient cooperation provided by Patient Controlled Sedation & Analgesia (PCSA) using propofol and fentanyl (Group II) when compared with anesthetist administered propofol/fentanyl (Group I) in 32 ASA I & II patients undergoing ESWL of renal or ureteric stones. Demographics of the patients and the duration of ESWL were similar in both groups. Dose of propofol/fentanyl used during the procedure was significantly higher in Group I patients as compared to group II (p less than 0.05). Interpatient variability in propofol requirement was reflected in both groups in the lack of significant correlation between propofol dose and procedure duration. PCSA provided a marginally higher degree of patient and surgeon satisfaction scores as compared to anesthetist administered propofol/fentanyl. Quick recovery was more consistent in the PCSA group as compared to group I patients.

Ventilation with nitrous oxide during open cholecystectomy increases the incidence of postoperative hypoxemia.

The effect of intraoperative use of air versus nitrous oxide (N2O) on postoperative oxygen (O2) saturation in blood was evaluated in 40 ASA Class I and II patients undergoing elective, open cholecystectomy. Patients were allocated randomly to two groups on the basis of whether they received air (Group A, n = 20) or N2O (Group B, n = 20) intraoperatively. Oxygen saturation was recorded on arrival of the patients in the ward, 24 h, and 48 h postoperatively. Although mean O2 saturation did not differ significantly (P > 0.05) between the groups over the first 24 h postoperatively, it was significantly higher (P < 0.05) in Group A as compared to Group B 48 h postoperatively. Incidence of hypoxemia (O2 saturation < 90%) was 40% in Group B as compared to 0% in Group A at the end of 48 h postoperatively. We conclude that the use of N2O during cholecystectomy is associated with a higher incidence of hypoxemia postoperatively.
