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.

Randomized Controlled Trial Comparative Study Clinical Trial
Intercostal nerve blockade producing analgesia after appendicectomy.
Intercostal nerve blockade of the 10th, 11th and 12th thoracic nerves on the right side was compared with i.m. papaveretum as analgesia after appendicectomy. Patients with intercostal nerve blockade had significantly less pain at 0, 4, 8 and 12 h after operation and required less papaveretum (mean 0.26 mg kg-1/24 h) compared with the controls (mean 0.62 mg kg-1/24 h). There were no complications in either group. Intercostal nerve blockade may provide better quality analgesia following appendicectomy than i.m. papaveretum alone.

Randomized Controlled Trial Comparative Study Clinical TrialLumbar plexus block in children: a comparison of two procedures in 50 patients.
Two techniques for blocking the lumbar plexus were prospectively evaluated in 50 children undergoing surgery in the hip region and randomly allocated to one of two equal groups. A variant of the "psoas compartment block" and the classic technique were used in groups 1 (n = 25) and 2 (n = 25), respectively. All procedures were carried out under light general anesthesia with the patients in the lateral position using insulated needles and electrical stimulation. ⋯ However, the distribution of analgesia differed: 23 (ipsilateral) lumbar and sacral plexus blocks and 2 (ipsilateral) lumbar blocks alone were produced in group 2, compared to 22 areas of anesthesia comparable to those that might be associated with a lumbar epidural block and two ipsilateral lumbar plexus blocks in group 1. The two techniques are not, therefore, mere variants of the same basic approach to the lumbar plexus. The procedure described by Winnie et al. (Anesthesiol Rev 1974;1:11-6) was more suitable for providing unilateral blockade than the "psoas compartment block."

Randomized Controlled Trial Comparative Study Clinical Trial[Combined sciatic/3-in-1 block. III. Prilocaine 1% versus mepivacaine 1%].
In a randomized, double-blind study, the efficacy of prilocaine 1% (group 1, 30 patients) was compared to mepivacaine 1% (group 2, 30 patients). All patients had a combined sciatic/femoral block for surgery of the lower extremities; a tourniquet was applied in each case. In each patient the block was done using 50 ml of a 1% solution of local anesthetic: 20 ml for the sciatic and 30 ml for the 3-in-1 block. ⋯ On the average, patients were pain-free for 254 min with prilocaine and 267 min with mepivacaine. Four of 30 patients (= 13%) in group 1 an 6 of 30 patients (= 20%) in group 2 had an unsatisfactory blockade and had to be supplemented by analgesics or general anesthesia. The finding of a significant correlation between the voltage necessary for stimulation and the efficacy of the blockade underlines the importance of correct stimulation when identifying the nerves.
