Randomized Controlled Trial Comparative Study Clinical TrialPremedication with intramuscular dixyrazine: (Esucos). A controlled double-blind comparison with morphine-scopolamine and placebo.
Ninety patients scheduled for general or orthopaedic surgical procedures were randomly assigned to receive one of three i.m. premedications: dixyrazine 0.5 mg kg-1; morphine 0.15 mg kg-1 and scopolamine 0.0065 mg kg-1; or placebo. The premedication was administered and evaluated in a double-blind fashion. The patients were anaesthetized with thiopentone, fentanyl, pancuronium, and ventilated with nitrous oxide in oxygen. ⋯ Morphine-scopolamine caused more postoperative dizziness than dixyrazine and placebo. Lack of recall was produced by both morphine-scopolamine and dixyrazine. It is concluded that premedication with dixyrazine is a useful alternative, especially in patients who have previously experienced postoperative nausea and vomiting.

Randomized Controlled Trial Comparative Study Clinical TrialEpidural versus combined spinal epidural block for cesarean section.
In a controlled study a single segment combined spinal epidural (CSE) block was compared with epidural block for cesarean section. Thirty healthy parturients were randomly divided into two groups. In both groups a T4 block was aimed at. ⋯ Apgar scores, blood gases and neurobehavioural evaluation did not show any differences between the two groups of neonates. No postspinal headache was noted. CSE block appears to combine the reliability of spinal block and the flexibility of epidural block while minimizing their drawbacks.

Randomized Controlled Trial Comparative Study Clinical TrialReduction of pain at venous cannulation in children with a eutectic mixture of lidocaine and prilocaine (EMLA cream): comparison with placebo cream and no local premedication.
The local analgesic efficacy of a cream formulation of lidocaine and prilocaine (EMLA) in reducing pain at venous cannulation was investigated in children scheduled for elective surgery. Forty children participated in a double-blind, randomized comparison between EMLA and inactive placebo cream. Another group of 18 children without any local treatment was studied as an additional control material. ⋯ No significant hormone responses were, however, detected. The lidocaine concentrations measured in venous blood taken from the application site of EMLA cream were low, and there were no measurable levels of lidocaine in simultaneous blood samples from the opposite extremity. In our opinion EMLA cream is safe and alleviates effectively the pain associated with venepuncture, and thus deserves a place in the routine premedication of children.

Randomized Controlled Trial Comparative Study Clinical TrialPatient-controlled analgesia: a controlled trial.
Thirty-six patients undergoing lower abdominal surgery were included in a prospective randomized controlled study to compare the effects of patient-controlled analgesia (PCA) and a standard intramuscular/intravenous treatment (conventional analgesia, CA) of postoperative pain. Morphine was used in both groups. There were no significant differences between the two analgesic regimens in respect of linear analogue pain scores, verbal pain-relief scores, amount of morphine used or side-effects. No treatment-induced alterations in vital values were experienced.

Randomized Controlled Trial Clinical Trial Controlled Clinical TrialNo increased incidence of postoperative sore throat after administration of suxamethonium in endotracheal anaesthesia.
Sixty patients were divided into two groups (A and B) of 30 patients each to investigate the effect of using suxamethonium in endotracheal anaesthesia on the incidence of postoperative sore throat. The patients were anaesthetized with thiopentone, fentanyl, droperidol, N2O and pancuronium. ⋯ The type 2 error (beta) was low (the risk of overlooking a "true" difference in incidence of 0.20 was calculated to be 0.04). These results contradict those of a recent study, which demonstrated an increased incidence of postoperative sore throat following the use of suxamethonium in mask anaesthesia.
