Randomized Controlled Trial Comparative Study Clinical Trial
Caudal block for postoperative analgesia in children.
A clinical trial was performed to compare the effects of intramuscular dihydrocodeine with caudal bupivacaine on postoperative pain and recovery in 181 children who had undergone either circumcision, inguinal herniotomy or orchidopexy performed under general anaesthesia. Linear analogues were used in assess level of consciousness and apparent pain. Recovery of consciousness was slower after caudal analgesia. For 90 minutes following circumcision there was significantly less pain and caudal analgesia, but better pain relief could not be demonstrated following inguinal herniotomy and orchidopexy.

Randomized Controlled Trial Clinical TrialModerate hypotensive anaesthesia for reduction of blood loss during total hip replacement.
Thirty-two consecutive patients scheduled for total hip replacement were randomly allocated to receive either neurolept anaesthesia or halothane anaesthesia. In the halothane group, systolic blood pressure was reduced to 10.69-13.33 kPa in normotensive patients, and to 13.33-16.0 kPa in hypertensive patients by adjusting the inspired halothane concentration and using supplementary fentanyl when necessary. ⋯ The average peroperative blood loss in the halothane group was 809 ml (range 250-1700 ml); this was significantly lower than in the neurolept anaesthesia group in which an average blood loss of 1909 ml (range 600-4900 ml) occurred. Moderate hypotensive halothane anaesthesia is recommended as an anaesthetic technique for total hip replacement.

Randomized Controlled Trial Clinical TrialAttenuation of the circulatory response to laryngoscopy and intubation by fentanyl.
The effects of fentanyl on arterial pressure and heart rate increases during laryngoscopy and intubation were studied in 45 normotensive, surgical patients, who were randomly allocated to three groups receiving 2 or 6 micrograms/kg of fentanyl or saline in a double-blind fashion before anaesthetic induction with thiopental. Fentanyl supplementation with 2 micrograms/kg significantly attenuated the arterial pressure and heart rate increases during laryngoscopy and intubation, and fentanyl, 6 micrograms/kg, completely abolished these responses. Moreover, fentanyl given during the induction decreased the amount of fentanyl needed during the operation. Respiratory depression was not observed during recovery.

Randomized Controlled Trial Clinical Trial
Changes in fetal TCPO2 values occurring during labour in association with lumbar extradural analgesia.
Forty-six of 64 high risk labours were managed with continuous lumbar extradural analgesia. Fetal heart rate (FHR) and continuous transcutaneous PO2 (tcPO2) measurements were made in the 64 patients. ⋯ These effects and the changes in FHR were not seen in the 18 mothers not receiving extradural analgesia. The supine position was associated with slightly smaller fetal tcPO2 values than the preferred lateral positions, with a significant worsening of the fetal tcPO2 values after induction of the extradural block although, overall, extradural analgesia neither improved nor impaired the fetal tcPO2.
