Randomized Controlled Trial Clinical Trial
Preoperative naproxen sodium reduces postoperative pain following arthroscopic knee surgery.
This study was undertaken to assess the efficacy of a single preoperative dose of naproxen sodium in reducing postoperative pain and length of day surgery stay in patients undergoing arthroscopic knee surgery. A randomized, double-blind clinical trial was carried out on 66 ASA I and ASA II patients scheduled for arthroscopic knee surgery. The treatment group (n = 26) received two capsules containing 275 mg of naproxen sodium each, and the control group (n = 40) received placebo. ⋯ There was no difference in the need for in-hospital postoperative analgesics or in the time to discharge. However, there was a difference in the use of analgesics after discharge (naproxen group 30.4% vs placebo group 71.4%) (P < 0.01). The results of this study suggest that a single preoperative dose of 550 mg naproxen sodium is effective in reducing postoperative pain in arthroscopic knee surgery, both in the immediate postoperative period and for up to 24 hr after the completion of surgery.

Randomized Controlled Trial Clinical Trial
Mask lung ventilation by ambulance personnel: a performance assessment.
We evaluated the ability of basic life support ambulance officers and anaesthetists to perform lung ventilation with a face mask. After induction of anaesthesia and institution of standardized airway conditions the ambulance officer or anaesthetist placed a mask on the patient's face and lung ventilation was commenced. The order of hand grip (one vs two hands) was randomized. ⋯ There was no difference in the mask leak when the professions were compared but ambulance officers had a lower mask leak with a two-handed grip at 20 cm H2O (P < 0.001). Anaesthetists had a greater incidence of gastro-oesophageal insufflation when a two-handed mask grip was utilized (P < 0.05). In healthy relaxed patients there appeared to be little difference between the ambulance officers and qualified anaesthetists in airway maintenance or mask-holding ability.
