AbstractSixty patients undergoing shock wave lithotripsy of gallbladder stones (ESWL) were randomly assigned to receive alfentanil either by infusion controlled by the attending anesthesiologist (standard treatment group, n = 31) or by analgesia controlled by the patient (PCA group, n = 29). Patients using PCA were allowed to self-administer 0.25 mg of alfentanil i.v. every minute as required. Data collected during treatment included the total dose of drug required, transcutaneous pCO2 values, verbal pain and sedation scores, visual analogue scale (VAS) patient satisfaction scores, and the incidence of nausea or vomiting. PCA patients used less alfentanil than the standard treatment group (PCA group: 12.8 micrograms/kg; standard treatment group: 44.3 micrograms/kg; mean values, P = 0.0001), tolerated significantly higher pain intensities and self-administered the narcotic only to moderate levels of pain but not to pronounced analgesia. Standard treatment patients reported lower levels of pain, were more sedated (P less than 0.05) and showed significantly higher transcutaneous pCO2 values. There was a trend towards a lower incidence of nausea or vomiting in PCA patients without reaching statistical significance. No significant difference with regard to patient satisfaction with pain relief could be demonstrated. Self-administered alfentanil during ESWL of gallbladder stones provided adequate analgesia with minimal side effects and high patient satisfaction. ESWL may represent a new and useful indication for PCA.
