Randomized Controlled Trial Clinical TrialProphylactic laryngo-tracheal aerosolized lidocaine against postoperative sore throat.
A randomized, double-blind study was carried out on 193 ASA I-II surgical patients to assess the effect of aerosolized lidocaine on sore throat, hoarseness and cough in connection with tracheal intubation. The study group received aerosolized lidocaine 100 mg 2 min before tracheal intubation, using a spray. The control group received no spray. ⋯ The patients were interviewed when leaving the recovery room and the next day in the ward. Specific questions were asked regarding sore throat, cough and hoarseness. There were no significant differences between the two groups, which suggests that topical anaesthesia of the mucosa of the upper airway is ineffective as a means of ameliorating airway complaints in connection with tracheal intubation.

Randomized Controlled Trial Clinical TrialA dose-range study of intrathecal meperidine combined with bupivacaine.
Twenty-one patients were included in a randomized study to receive either 10 mg of 0.5% hyperbaric bupivacaine alone or combined with 0.05, 0.1, 0.2, 0.3, 0.4 or 0.5 mg.kg-1 meperidine for spinal anaesthesia. Sensory blockade was assessed by pin prick, motor blockade by the Bromage scale, and postoperative analgesia by VAS scores and by the time before the first demand for analgesia. Spinal meperidine did not change the duration of sensory blockade, but induced a dose-related increase in postoperative efficient analgesia. Spinal meperidine might be considered as a means to obtain postoperative analgesia in the hours immediately following surgery.

Randomized Controlled Trial Clinical TrialContinuous coeliac plexus blockade plus intermittent wound infiltration with bupivacaine following upper abdominal surgery: a double-blind randomised study.
In this double-blind trial, we observed the effect of intermittent wound infiltration with local anaesthetic plus continuous coeliac plexus blockade on postoperative pain relief, pulmonary function, the neuroendocrine and acute phase protein response following upper abdominal surgery. In Group A (n = 10) patients received bupivacaine intermittently into the wound and continuously into the coeliac plexus following an initial bolus. A total of 862.5 mg of bupivacaine was used over 12 h with no observed toxicity. ⋯ Significant reductions in serum glucose and cortisol were achieved (P less than 0.05), suggesting that afferent neural blockade was partially effective in attenuating the neuroendocrine response. However, the postoperative rise in interleukin-6 was not affected by this technique. It is concluded that total afferent neural blockade cannot be achieved with peripheral wound and coeliac plexus administration of relatively large doses of local anaesthetic during upper abdominal surgery.

Randomized Controlled Trial Clinical TrialHaemodynamic changes during spinal anaesthesia with slow continuous infusion or single dose of plain bupivacaine.
Forty elderly patients, scheduled for orthopaedic surgery of the hip or knee were studied. Twenty patients received a single-dose spinal anaesthesia with 3 ml of plain 0.5% bupivacaine (SDSA group). Twenty patients received continuous spinal anaesthesia using a 32- or 22-gauge catheter. ⋯ The mean maximum decreases in CVP and MAP were quite similar in the CSA and SDSA group (2.1 vs 2.8 mmHg (0.3 vs 0.4 kPa) and 17 vs 21 mmHg (2.3 vs 2.8 kPa), respectively) (n.s.). Six patients in the SDSA group and four patients in the CSA group needed sympathomimetic medication. It is concluded that titration of bupivacaine for spinal anaesthesia caused only minor haemodynamic changes which were similar to those after single-dose spinal bupivacaine.

Randomized Controlled Trial Clinical TrialAcupuncture treatment of severe knee osteoarthrosis. A long-term study.
Acupuncture treatment of patients waiting for arthroplasty surgery. ⋯ Acupuncture can ease the discomfort while waiting for an operation and perhaps even serve as an alternative to surgery. Seven patients have responded so well that at present they do not want an operation. (USD 9000 saved per operation).
