Randomized Controlled Trial Clinical Trial
The influence of timing of ketorolac administration on post-operative analgesic requirements following total abdominal hysterectomy.
One hundred and thirty-seven patients were studied to assess whether the timing of a dose of ketorolac affected cumulative morphine requirements during the first 12 post-operative hours. Pain, sedation and nausea scores, respiratory rate and degree of operative blood loss were also recorded. Thirty-six patients (group A) were given placebo injections pre- and intra-operatively. ⋯ Thus, the timing of ketorolac administration made no difference to overall morphine consumption. Pain, nausea, sedation and respiratory rate scores were similar in all four groups. There was a significantly greater blood loss in patients receiving ketorolac (groups B, C and D) compared with those receiving placebo alone (group A).

Randomized Controlled Trial Clinical Trial
Analgesic effect of intra-articular bupivacaine or diamorphine after arthroscopic surgery of the knee joint in day-case patients.
A prospective, randomized, double-blind, controlled study was conducted to assess the efficacy of intra-articular bupivacaine and diamorphine. Ninety-six day-case patients were allocated randomly to receive intra-articular injections of either 20 mL 0.9% saline (control, n = 35), 20 mL 0.5% plain bupivacaine (n = 31), or 20 mL 0.9% saline with 5 mg diamorphine (n = 30) prior to tourniquet release. ⋯ Intra-articular analgesics conferred a noticeable improvement in patient comfort. First, the quantity of supplementary analgesia required prior to discharge was significantly reduced (P = 0.016); second, patients reported a less disturbed night's sleep (P = 0.034).

Randomized Controlled Trial Clinical Trial
Mivacurium or vecuronium for muscular relaxation in day-case surgery.
Anaesthetic agents for day-case surgery ideally should have a short duration of action. This study was designed to compare the efficacy and safety of mivacurium and vecuronium for healthy adults undergoing dental day-case surgery. Thirty fit healthy adult patients (ASA I or II) randomly received either mivacurium 0.15 mg kg-1 (n = 15) or vecuronium 0.1 mg kg-1 (n = 15). ⋯ One patient in the mivacurium group had a low plasma cholinesterase concentration (0.43 ku L-1); recovery times however, fell within the 95% confidence intervals (CI) for the group. There was no correlation between cholinesterase levels and recovery time. Mivacurium may be the more appropriate agent for dental day-case surgery because it has a shorter duration of action and does not generally require antagonism with an anticholinesterase.

Randomized Controlled Trial Comparative Study Clinical Trial
Total intravenous anaesthesia using propofol, gamma-hydroxybutyrate or midazolam in combination with sufentanil for patients undergoing coronary artery bypass surgery.
Total intravenous anaesthesia (TIVA) using propofol, gamma-hydroxybutyrate (GHB) or midazolam in combination with sufentanil was investigated in 45 patients undergoing coronary artery bypass grafting (CABG). Anaesthesia was induced with sufentanil, etomidate and pancuronium. After endotracheal intubation, anaesthesia was continued with sufentanil (2 micrograms kg-1 h-1) for all patients. ⋯ No electrocardiographical signs of ischaemia were observed in any patient. In the case of propofol and midazolam, gamma-hydroxybutyrate showed adequate haemodynamic stability especially after induction of anaesthesia and may also be a suitable agent for total intravenous anaesthesia in patients with coronary artery disease. However, during sternotomy, supplementary administration of opioids was required.

Comparative Study Clinical Trial Controlled Clinical Trial
The influence of controlled mandatory ventilation (CMV), intermittent mandatory ventilation (IMV) and biphasic intermittent positive airway pressure (BIPAP) on duration of intubation and consumption of analgesics and sedatives. A prospective analysis in 596 patients following adult cardiac surgery.
The aim of the study was the determination of the influence of ventilation modes on the consumption of analgesics and sedatives, duration of intubation and pulmonary gas exchange. Assist/controlled mandatory ventilation (S-CMV, 123 patients), synchronized intermittent mandatory ventilation (S-IMV, 431 patients) and biphasic positive airway pressure ventilation (BIPAP, 42 patients) were compared in a prospective, controlled, open clinical trial over an 18-month period. Five hundred and ninety-six adult patients with normal pulmonary function before surgery and uneventful course following coronary artery bypass graft surgery were studied. ⋯ We conclude that ventilatory support with BIPAP reduces the consumption of analgesics and sedatives, and the duration of intubation. The possibility of unrestricted spontaneous breathing in all phases of the respiratory cycle is considered to be the reason. BIPAP seems to be an alternative to S-CMV and S-IMV in short-term ventilated patient.
