Randomized Controlled Trial Comparative Study Clinical Trial[Evaluation of 2 dosages of fentanyl in caudal anesthesia. A prospective randomized double-blind study].
A caudal block is currently performed in children. A randomized and double blind study including two dosages of fentanyl: 0.5 microgram.kg-1 (group I) and 1 micrograms.kg-1 (group II) in association with bupivacaine 0.25% at a dosage of 1 mL.kg-1 was carried out. Two groups of 25 children undergoing urogenital or orthopaedic surgery participated in this study. ⋯ Furthermore, recovery of anaesthesia was rapid and calm. The frequency of nausea and vomiting was respectively 24% and 20% in groups I and II and did not require any specific therapy. Therefore it appears that caudal block with bupivacaine 0.25% and fentanyl 0.5 microgram.kg-1 is a very satisfactory technique in children when indicated.

Randomized Controlled Trial Clinical Trial[Value of ilio-hypogastric block in appendectomy in children].
This prospective study aimed to evaluate the efficiency of ilio-hypogastric nerve block for control of post appendicectomy pain in children. Forty-two children aged 3-15 years scheduled for appendicectomy were anaesthetized in the same way. After randomization, a preoperative ilio-hypogastric nerve block was performed in 21 patients. ⋯ Five inefficient blocks were recorded. No complications were noted. Ilio-hypogastric block was found to be safe and efficient for control of post-appendicectomy pain in most children.

Randomized Controlled Trial Comparative Study Clinical Trial[Hemodynamic effect of intrathecal clonidine].
Intrathecal administration of bupivacaine and clonidine results in a significant prolongation of both motor and sensitive blocks but side effects-hypotension and bradycardia-are observed. We compared two groups of patients allocated randomly. ⋯ Some possible explanations are discussed. No complications due to clonidine were observed.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparative study of sufentanil and fentanyl in urologic surgery in adults].
Sufentanil is compared with fentanyl as a supplement to N2O isoflurane anaesthesia in a double blind study of 30 elderly patients undergoing major urological surgery. Comparison is made with respect to 1) haemodynamic (heart rate, blood pressure) responses during surgery and recovery; 2) time to extubation after the end of surgery; 3) Postoperative analgesia. No difference is observed between the two groups with respect to demographic data, duration of surgery, and total doses of muscle relaxants. ⋯ Times between end of surgery and extubation are different: 77 +/- 13 min the sufentanil group versus 57 +/- 22 min the fentanyl group (p < 0.05). Use of analgesia is significantly delayed in the sufentanil group. It is suggested that sufentanil, in elderly patients, provides a better haemodynamic stability and a greater residual analgesia than fentanyl in the immediate postoperative period.

Randomized Controlled Trial Comparative Study Clinical Trial[Analgesia with intra-articular injection of buprenorphine after surgery of the shoulder].
The effect of 10 ml of intra-articular buprenorphine (0.30 mg) or normal saline on postoperative pain after shoulder surgery was studied in a randomized, prospective, double-blind study in 30 ASA I-II patients receiving general anaesthesia. The pain scores (Five Point Scale ranging from "no pain" to "unbearable pain" and Visual Analog Pain Scale) 1, 2, 3, 4, 6 and 24 hours after surgery, time to first analgesic use and total 6-hours and 24-hours analgesic requirements were recorded. VAPS was significantly lower in the buprenorphine group compared with placebo-treated patients one hour after surgery (p < 0.05). ⋯ No significant differences were detected in total 24-h analgesic requirements between the two groups. These results indicate that intra-articular injection of buprenorphine after shoulder surgery provides short analgesia. This effect may be mediated by systemic absorption.
