Comparative StudyThe effect of continuous epidural analgesia on postoperative pain, rehabilitation, and duration of hospitalization in total knee arthroplasty.
Efficacies of three alternate methods of postoperative analgesia were studied in 156 patients who had total knee arthroplasty (TKA). Forty-two of these patients received parenteral meperidine hydrochloride or morphine (Group 1), 58 patients received periodic epidural injections of morphine (Group 2), and 56 patients received continuous epidural infusions of bupivacaine hydrochloride and Duramorph (Group 3). The postoperative course of all patients was documented in terms of the incidence and severity of pain, range of joint motion, duration of hospitalization, and occurrence of complications. ⋯ However, the use of epidural analgesia did not reduce the incidence of complications, including nausea. Continuous infusion of epidural bupivacaine and Duramorph provided good-to-excellent control of postoperative pain after TKA. However, better analgesics are needed to reduce the high incidence of side effects associated with various treatment methods.

Randomized Controlled Trial Comparative Study Clinical Trial
Anesthesia for craniotomy: a double-blind comparison of alfentanil, fentanyl, and sufentanil.
Using a prospective, randomized, and double-blind study design, alfentanil (n = 15), fentanyl (n = 14), or sufentanil (n = 16), in combination with N2O, were administered to patients undergoing craniotomy for supratentorial tumor resection. Physicians were given two syringes, one of which was labeled as "load" for the initial loading dose and the other as "maintenance" for continuous infusion. The concentration of drug in each syringe was adjusted to permit administration on a milliliter per kilogram basis. ⋯ Administration of isoflurane, antihypertensive medications, and naloxone were not different among groups. Although decreases in blood pressure seen with induction were similar among groups, alfentanil-treated patients received ephedrine more frequently before intubation. Thirty minutes after entry into the postanesthesia recovery area, respiratory rate and pH were lowest in sufentanil-treated patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Comparative Study Clinical Trial Controlled Clinical TrialA study of the comparative efficacy of four common analgesics in the control of postsurgical dental pain.
Four common oral analgesics were tested in a single-blind trial to determine their relative efficacy in the management of postsurgical pain in 103 patients who had their impacted third molars surgically removed under general anesthesia. The analgesics tested were acetylsalicylic acid (26 patients), ibuprofen (26 patients), a paracetamol/codeine/caffeine combination (Solpadeine) (25 patients), and dihydrocodeine (26 patients). ⋯ Dihydrocodeine was found to be a poor analgesic in this pain model. There were no adverse reactions to any of the preparations.
