Review Meta Analysis
Remifentanil for general anaesthesia: a systematic review.
We performed a quantitative systematic review of randomised, controlled trials that compared remifentanil to short-acting opioids (fentanyl, alfentanil, or sufentanil) for general anaesthesia. Eighty-five trials were identified and these included a total of 13 057 patients. ⋯ Remifentanil had no overall impact on postoperative nausea (1.03, 0.97-1.09) or vomiting (1.06, 0.96-1.17), but was associated with twice as much shivering (2.15, 1.73-2.69). Remifentanil does not seem to offer any advantage for lengthy, major interventions, but may be useful for selected patients, e.g. when postoperative respiratory depression is a concern.

Randomized Controlled Trial
M-Entropy guidance vs standard practice during propofol-remifentanil anaesthesia: a randomised controlled trial.
Seventy-two patients undergoing routine surgical procedures under propofol-remifentanil anaesthesia were randomly assigned to receive either standard clinical practice (n = 35) or standard practice plus monitoring of depth of anaesthesia with M-Entropy (n = 37). Patients in the standard practice group received more propofol than the entropy group (mean (SD) 95 (14) vs 81 (22) microg.kg(-1).min(-1), respectively; p < 0.01), and less remifentanil (0.39 (0.08) vs 0.46 (0.08) microg.kg(-1).min(-1), respectively; p < 0.001). ⋯ Both regimens resulted in fast recovery with no clinical advantage for either one. There were no significant differences in haemodynamic parameters, postoperative nausea and vomiting or satisfaction with the procedure.

An anaesthetic charity 'Mothers of Africa' has been established as a link between the academic departments of anaesthesia in Togo and Benin and the University Hospital of Wales. Visits by UK consultant anaesthetists have identified a number of clinical areas where collaborative working in both classroom and theatre has the potential to improve outcomes in maternal mortality and morbidity.

Randomized Controlled Trial
Comparison of the incidence and severity of cough induced by sufentanil and fentanyl: a prospective, randomised, double-blind study.
We compared the incidence and severity of cough following a bolus of sufentanil with that following fentanyl in 510 patients, randomly allocated to receive sufentanil 0.3 microg.kg(-1), fentanyl 3 microg.kg(-1) or 5 ml sterile water intravenously over 5 s. Coughing was graded depending on the number of coughs as mild (1-2), moderate (3-5) and severe (> 5). ⋯ Sufentanil was also associated with a lesser severity (p = 0.039) of coughing compared with fentanyl. We conclude that equipotent boluses of sufentanil and fentanyl increase the incidence of cough, although the incidence and severity of coughing with sufentanil are less than those with fentanyl.

Randomized Controlled Trial
Pre-operative analgesia with rectal diclofenac and/or paracetamol in children undergoing inguinal hernia repair.
Both rectal diclofenac and paracetamol are commonly used to treat acute postoperative pain in children but combining them to improve the quality of analgesia is controversial. This study aimed to detect whether the pre-operative combined administration of rectal diclofenac and paracetamol is superior to either drug alone. One hundred and eight patients were randomly assigned to receive either rectal diclofenac 1 mg.kg(-1) or paracetamol 40 mg.kg(-1) or their combination 1 h prior to surgery. ⋯ If the patients experienced a pain score of 2 or more, morphine was given. The total dose of morphine and number of doses required were recorded. Children who received the rectal diclofenac-paracetamol combination experienced a lower pain scale and a decreased need for morphine compared with children receiving each drug alone.
