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.

Our understanding of how adults learn has undergone many advances in the last few years. This information needs to be used to build more effective training in anaesthesia throughout the world, especially in those countries where the need to train large numbers is critical to the development of effective medical services. Training a new generation of teachers is a key part of this.

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.
