Randomized Controlled Trial Comparative Study Clinical Trial
An open, randomized comparison of alfentanil, remifentanil and alfentanil followed by remifentanil in anaesthesia for craniotomy.
We studied 52 adults undergoing elective craniotomy, allocated randomly to one of three opioid treatments: alfentanil 50 micrograms kg-1 followed by 0.833 microgram kg-1 min-1 until dural closure (group Alf.); alfentanil 50 micrograms kg-1 followed by 0.833 microgram kg-1 min-1 for 2 h, then remifentanil 0.25 microgram kg-1 min-1 (group Alf.-Remi.); or remifentanil 1 microgram kg-1 followed by 0.5 microgram kg-1 min-1 reducing to 0.25 microgram kg-1 min-1 after craniotomy (group Remi.). Anaesthesia was maintained with infusion of propofol and 66% nitrous oxide in oxygen. Infusions of propofol and remifentanil were stopped at head bandaging. ⋯ Times to tracheal extubation and obey commands were similar in all groups. In all patients in group Alf.-Remi. and group Remi., the trachea was extubated 27 min from the end of anaesthesia; three patients in group Alf. were slower to recover. Use of analgesia in the recovery room and time to transfer to the neurosurgical unit were similar in the three groups.

Randomized Controlled Trial Comparative Study Clinical Trial
Ketorolac, diclofenac and ketoprofen are equally efficacious for pain relief after total hip replacement surgery.
We have compared the efficacy of ketorolac 30 mg i.v. followed by infusion at a rate of 90 mg/15.5 h, with that of diclofenac 75 mg followed by infusion of 75 mg/15.5 h or ketoprofen 100 mg followed by infusion of 100 mg/15.5 h, on postoperative pain in 85 patients after hip replacement surgery under spinal anaesthesia in a prospective, double-blind, randomized study. Supplementary analgesia was administered during the 16-h postoperative period with bolus doses of fentanyl delivered by a patient-controlled analgesia system. ⋯ Median VAS scores were low over the entire study in each group and there was no significant difference between groups. No serious adverse events were recorded.

Percutaneous tracheostomy is being used increasingly in the intensive care unit and endoscopic control of this procedure affords an improved level of safety. Training in such new minimal access techniques can be a significant risk factor in patient outcome. ⋯ We present a method of training in percutaneous endoscopic tracheostomy using a simulation model based on animal tissue. Our experience with this model is reported.
