Randomized Controlled Trial Comparative Study Clinical TrialAnalgesia following arthroscopic knee surgery. A controlled study of intra-articular morphine, bupivacaine or both combined.
In a double-blind, randomised controlled trial, we studied 40 patients who received one of four intra-articular injections at the end of arthroscopic surgery. Each group contained ten patients. The patients in Group 1 received normal saline 25 ml; those in Group 2 received bupivacaine 0.25% 25 ml; those in Group 3 received morphine 5 mg in normal saline 25 ml; and those in Group 4 received a combination of bupivacaine 0.5% 12.5 ml and 5 mg of morphine made up to 25 ml with normal saline to produce the same bupivacaine concentration as Group 2. ⋯ Group 4 had the lowest pain scores over the recorded period compared with the other groups. The need for supplemental analgesia was significantly lower (P < 0.05) in the treatment Groups 2, 3 and 4 compared to the control Group 1. There was no significant difference in supplemental analgesic requirements between Groups 2, 3 and 4.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical TrialBackground infusion with patient-controlled analgesia: effect on postoperative oxyhaemoglobin saturation and pain control.
The aim of this study was to determine whether the addition of a background infusion (BI) to patient-controlled analgesia (PCA) would lead to significantly improved pain control or poorer oxyhaemoglobin saturation (SpO2) after gynaecological surgery. Sixty-two patients were studied for 24 hours postoperatively; pain scores and morphine dose were recorded hourly, SpO2 was recorded every 10 seconds. ⋯ Despite the increased morphine dose pain scores also were similar in the two groups. Addition of a BI at 1 mg/hr did not confer any advantage over PCA alone and is not recommended when PCA is used in this patient group.

Laparoscopic surgery minimises postoperative morbidity. Patient benefits include reduction in postoperative pain, better cosmetic result and quicker return to normal activities. Hospital stay is shortened resulting in a reduction in overall medical cost. ⋯ An appraisal of the potential problems is essential for optimal anaesthetic care of patients undergoing laparoscopic surgery. Appropriate anaesthetic techniques and monitoring facilitate surgery and allow early detection and reduction of complications. The need for rapid recovery and short hospital stay impose additional demands on the anaesthetist for skillful practice.

Comparative StudyChemical dependence in anaesthetic registrars in Australia and New Zealand.
The Supervisors of Anaesthetic Training in Australia and New Zealand were surveyed and asked to report any cases of chemical dependence from anaesthetic registrars at their hospital from 1981 to 1991. From 83 questionnaires there were 65 (78%) returned. There were 14 departments (22%) with experience of one or more cases during this interval. ⋯ It is estimated that 1.3% of those who entered anaesthetic training during the interval were recognised to become chemically dependent during their training. Follow-up was available on only six of the 13 registrars and only one was reported to have completed training. The results of this survey indicate that chemical dependence is already a major health problem amongst anaesthetic registrars in Australia and New Zealand.

Randomized Controlled Trial Comparative Study Clinical TrialHigh-dose adrenaline in adult in-hospital asystolic cardiopulmonary resuscitation: a double-blind randomised trial.
Forty intensive care unit patients requiring cardiopulmonary resuscitation were randomised to receive either the standard dose of adrenaline (1 mg every five minutes) or high-dose adrenaline (10 mg every five minutes). In the majority of patients, overwhelming sepsis was the major contributing factor leading to cardiac arrest. In this group of patients no difference could be detected in response to high-dose adrenaline compared with the standard dose. Although no side-effects were noted with this high dose of adrenaline, more investigation is required prior to its routine use in cardiopulmonary resuscitation.
