Randomized Controlled Trial Clinical Trial
Postoperative recovery after general anaesthesia with and without retrobulbar block in retinal detachment surgery.
This study was to determine whether general anaesthesia plus retrobulbar block would be a better anaesthetic technique than general anaesthesia alone in retinal detachment surgery. Twenty-eight patients were allocated randomly to either general anaesthesia with retrobulbar block or general anaesthesia alone. The anaesthetist involved was blinded as to whether a retrobulbar block was performed or not. ⋯ Those who received general anaesthesia plus block recovered significantly more rapidly than those receiving general anaesthesia alone. The time to opening of eyes on command (p less than 0.05), telling the correct date of birth (p less than 0.01), reaching a full recovery score (p less than 0.005) and performing a simple motor task (p less than 0.025) was shorter in patients with general anaesthesia plus block. Thus general anaesthesia plus retrobulbar block was superior to general anaesthesia alone in terms of pain and recovery after operation.

Arterial oxygen saturation was measured by pulse oximetry in 105 children (aged 2 weeks-14 years) during recovery from general anaesthesia. Oxygen saturation was monitored continuously from the time that anaesthesia ended in the operating theatre until the children were fit to leave the recovery ward. All children breathed room air during transfer to the recovery area; 81 children continued to breathe room air in the recovery ward while the remainder received supplementary oxygen. ⋯ The administration of 100% oxygen at the end of anaesthesia had no effect on the incidence of early hypoxaemia which was greatest in children whose trachea had been intubated. Late hypoxaemia was associated most commonly with crying and breath-holding and was reduced significantly by supplemental oxygen. The oxygen saturation of children on return to the ward was significantly lower than the pre-operative value (p less than 0.001).

Comparative Study
[Caudal anesthesia combined with general anesthesia in comparison with general anesthesia in ambulatory circumcision].
In 100 boys (5.9 +/- 3.2 years old) undergoing outpatient circumcision, analgesia was provided with 0.375% bupivacaine 1 ml/year of age by caudal injection (group I), administered after induction of general anesthesia. This group was compared with 100 boys (6.3 +/- 3.4 years old), who received only general anesthesia (group II). The puncture technique described was free of complications and the caudal blocks were 98% successful. ⋯ In 83% the effect of late postoperative analgesia worked so well that no subsequent analgesic was given. In 15% the pain relief lasted 6.3 +/- 2.5 h. The excellent postoperative pain relief produced by caudal anesthesia justifies its frequent use for children subjected to genital surgery.(ABSTRACT TRUNCATED AT 250 WORDS)
