Randomized Controlled Trial Comparative Study Clinical TrialNo additional analgesic effect of intra-articular morphine or bupivacaine compared with placebo after elective knee arthroscopy.
Intra-articular pain prophylaxis is a controversial measure, adding costs although the benefits are still disputed. We wanted to evaluate the effects of intra-articular opioid or local anaesthesia or a combination of the two on postoperative analgesia and analgesic consumption after elective knee arthroscopy. ⋯ Intra-articular administration of morphine or bupivacaine is not indicated after elective knee-arthroscopy in patients with minor pre-operative pain and a small surgical trauma.

Recall of awareness during cardiac anaesthesia: influence of feedback information to the anaesthesiologist.
We interviewed 303 cardiac surgery patients to evaluate the incidence of intraoperative awareness with recall. First, we randomly interviewed 99 patients, of whom four patients (4%) reported awareness and recall. We informed the cardiac anaesthesiologists of the results of these interviews, and we also gave general information regarding means to reduce awareness and recall during general anaesthesia. ⋯ The patients with awareness were significantly younger than those not aware. In conclusion, with educational measures and vigilance over the problem, the incidence of intraoperative awareness during cardiac anaesthesia may be reduced. The incidence figure of 1.5% we observed is of the magnitude reported recently by others with modern cardiac anaesthesia techniques.

Randomized Controlled Trial Clinical TrialReduced hypoxic chemosensitivity in partially paralysed man. A new property of muscle relaxants?
It was hypothesized that non-depolarizing neuromuscular blocking agents impair hypoxic chemosensitivity in man. ⋯ It is concluded that non-depolarizing neuromuscular blocking agents impair hypoxic ventilatory regulation. Further experimental studies are warranted to fully describe the mechanism(s) responsible for this interaction.

Randomized Controlled Trial Clinical TrialPostoperative pain relief by topical lidocaine in the surgical wound of hysterectomized patients.
To improve postoperative analgesia, local anesthetics have been administered perioperatively as infiltration or as aerosol in the surgical area. A previous study showed good analgesic effects by topical lidocaine in the wound in minor extraabdominal surgery (herniorraphy), while the same treatment in minor lower laparothomies did not improve postoperative analgesia. The present study investigated the effect of topical wound anesthesia using lidocaine aerosol on postoperative pain following major lower abdominal surgery. ⋯ A single dose of lidocaine aerosol topically administered in the surgical wound of hysterectomy patients improved analgesia during the first postoperative day with minimal risk of side effects.

Randomized Controlled Trial Clinical TrialPatient-controlled analgesia with morphine and droperidol following caesarean section under spinal anaesthesia.
The addition of droperidol to morphine for patient-controlled analgesia reduces the incidence of nausea and vomiting, but may result in unwanted side effects. ⋯ The addition of droperidol 10 mg to morphine 60 mg for PCA following caesarean section under spinal anaesthesia reduces the incidence of nausea and emesis, but may result in drowsiness, limiting the usefulness of the technique.
