Randomized Controlled Trial Comparative Study Clinical Trial
Self-administered intravenous and intramuscular pethidine. A controlled trial in labour.
In a randomised controlled trial of mothers in labour intramuscular pethidine 150 mg, repeated if necessary, was compared with self-administered intravenous pethidine (0.25 mg/kg available at 10-min-intervals). Each mother agreed to have either method of pain relief and could opt for epidural block. ⋯ There were no differences in mean Apgar scores between the babies in the groups. In mothers who do not choose epidural block, similar pain relief is afforded by adequate intramuscular pethidine or self-demand intravenous pethidine; however, intravenous self-administration is more efficient since the pain relief is achieved with a lower dose of pethidine.

Randomized Controlled Trial Comparative Study Clinical TrialEpidural versus general anaesthesia for total hip arthroplasty in elderly patients.
Sixty elderly patients were given at random either epidural analgesia with bupivacaine 0.75% or general anaesthesia with thiopentone, fentanyl, pancuronium, N2O/O2 for total hip replacement. Preoperatively the patients were of equal physical status with normal and similar laboratory values. All patients were mentally normal for their age. ⋯ Two patients in the epidural group had symptoms of pulmonary embolism postoperatively. Thus elderly patients appear to do better after hip replacement with less deterioration of cerebral and pulmonary functions when given epidural analgesia than when surgery is performed under general anaesthesia. These patients should therefore be offered epidural analgesia whenever possible.

Effect of baricity on spinal anaesthesia with amethocaine.
Amethocaine 1% solution was mixed with equal volumes of water, 0.9% saline or 10% dextrose to prepare respectively, hypobaric, isobaric and hyperbaric solutions which were compared for intradural spinal anaesthesia in 60 patients. Thirty patients received 10 mg and 30 patients received 15 mg of amethocaine. Injections were made with the patients in the lateral recumbent position and the operating table was horizontal during and after injection. ⋯ The mean spread of analgesia after the hyperbaric solution was five dermatomes greater than after the other two solutions, but the extent of analgesia was not significantly different whether amethocaine 10 mg or 15 mg was injected. The mean duration of analgesia after the hyperbaric solution was 285 min compared with 332 min and 360 min after the isobaric and hypobaric solutions respectively. The mean duration of analgesia after amethocaine 15 mg was significantly greater than after 10 mg.

Randomized Controlled Trial Comparative Study Clinical Trial
The neonatal neurobehavioral effects of bupivacaine, mepivacaine, and 2-chloroprocaine used for pudendal block.
The neonatal neurobehavioral effects of bupivacaine, mepivacaine, and 2-chloroprocaine used in random sequence for pudendal block anesthesia were studied. The neurobehavioral status of 54 infants was studied 4 and 24 hours after delivery. ⋯ Mean mepivacaine levels in neonatal capillary blood at 4 hours of age were low (0.10 +/- .02 microgram/ml) compared with those in previous studies because of the short interval between maternal injection and delivery (13 +/- 3 min). Bupivacaine gave higher neonatal capillary blood levels (0.15 microgram/ml at 4 hours of age) than previously reported, but the drug still produced no detectable neonatal neurobehavioral effects.

Comparison of carbonated bupivacaine and bupivacaine hydrochloride for extradural anaesthesia.
A double-blind comparison of carbonated bupivacaine and bupivacaine hydrochloride in extradural anaesthesia was performed in 40 patients. No significant differences in the onset times, sensory blockade, motor blockade and duration of anaesthesia were demonstrated. Carbonated bupivacaine does not appear to offer any advantage over the hydrochloride salt for extradural anaesthesia.
