A consultant anaesthetist gave a diclofenac suppository for postoperative pain to a patient having four teeth extracted under general anaesthesia in the dental surgery. He did not seek the patient's specific consent preoperatively for use of the suppository but told her afterwards what he had done. Charged before the professional conduct committee of the General Medical Council with failure to obtain informed consent and assault, the anaesthetist was found guilty of serious professional misconduct and admonished. This decision has far reaching implications and has caused great concern.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative apnea, bradycardia, and oxygen desaturation in formerly premature infants: prospective comparison of spinal and general anesthesia.
Eighteen formerly premature infants scheduled for inguinal herniorrhaphy and who were less than 51 wk postconceptional age were assigned to either the general anesthesia group (GA: atropine, halothane, and nitrous oxide) or the spinal anesthesia group (SA: hyperbaric tetracaine). Twelve-hour, three-channel continuous recordings of respiratory rate (chest wall impedance), electrocardiogram (ECG), and hemoglobin O2 saturation (SpO2) were obtained preoperatively and after surgery. ⋯ There were no differences in the incidence of postoperative central apnea. We conclude that spinal anesthesia reduces postoperative hemoglobin oxygen desaturation and bradycardia in formerly premature infants undergoing inguinal herniorrhaphy.

Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled analgesia following caesarean section under general anaesthesia: a comparison of fentanyl with morphine.
This prospective, randomised, double-blind study compared PCA fentanyl with PCA morphine for post-Caesarean section analgesia. Following a standardised general anaesthetic, 37 women were allocated to receive either fentanyl (n = 18) or morphine (n = 19). The PCA was commenced after the women had been made comfortable in the postanaesthetic recovery room with the appropriate opioid solution (mean dose required = fentanyl 375 micrograms or morphine 16 mg). ⋯ Both analgesic solutions provided effective analgesia for a mean of 37 hr with high levels of patient satisfaction, and there were no differences in VAS scores for pain and patient satisfaction, or for side effects (nausea, itch, and sleepiness) between fentanyl or morphine. However, more patients in the fentanyl group required supplementary boluses or alterations to the PCA settings (13/18 vs 4/19: P = 0.005), and one patient was removed from the study due to inadequate analgesia. We conclude that fentanyl is not recommended for routine PCA use following Caesarean section.

Randomized Controlled Trial Comparative Study Clinical Trial
The effect of isoflurane versus balanced anesthesia on rocuronium's pharmacokinetics and infusion requirement.
To compare the effects of two anesthetic techniques, balanced and isoflurane anesthesia, on the response to an intubating dose and an infusion of rocuronium, and on rocuronium's pharmacokinetics. ⋯ The similarity of response to an intubating dose and an infusion of rocuronium suggests that clinicians need not alter the dose or rate of rocuronium administration during isoflurane anesthesia with a of duration less than 1 hour. However, the greater clearance of rocuronium, in light of the similarity of infusion requirements, suggests that isoflurane potentiates rocuronium compared with balanced anesthesia.
