Randomized Controlled Trial Clinical Trial
Intranasal fentanyl titration for postoperative pain management in an unselected population.
A randomized, double-blind study was undertaken to investigate the suitability of intranasally administered fentanyl for postoperative pain management under routine conditions in an unselected population. For postoperative pain relief, patients received either 0.027 mg fentanyl intranasally and sodium chloride 0.9% intravenously (intranasal group, n = 53) or sodium chloride 0.9% intranasally and 0.027 mg fentanyl intravenously (intravenous group, n = 59). These doses were repeated every 5 min until the patients were free of pain or refused further analgesia. ⋯ At the 15 min measurement point, numerical rating scale pain intensity and at the 10 and 20 min point, verbal rating scale pain intensity was significantly lower in the intravenous group. The incidence of side effects was low in both groups and no patient complained of intranasal pain. Intranasally administered fentanyl would appear to be suitable for the management of postoperative pain.

Three portable suction devices were evaluated and compared with a wall-mounted vacuum driven suction unit. The Repro-med Res-Q-Vac, the Dräger Sujector 2000 and the Laerdal suction unit were assessed by measuring the time taken to aspirate 140 ml of mock gastric contents. ⋯ These compare favourable with the Ohmeda suction unit (7.27 (6.2-8.9)). Each type of device has advantages and disadvantages when factors such as size, power supply and portability are considered, and each will be the most suitable for a particular situation.

A 30-week newborn patient presented with acute respiratory obstruction due to a large pharyngeal teratoma. At laryngoscopy no view of the larynx was obtained, and a tracheal tube was unintentionally passed blindly into the oesophagus. This relieved the obstruction by anterior displacement of the mass.

Randomized Controlled Trial Comparative Study Clinical Trial
A new epidural catheter. Closer eyes for safety?
A new design of epidural catheter with three lateral eyes placed in close proximity to its closed end is described. Prototype models of this catheter were tested in 200 obstetric and surgical patients. In a single-blind randomised study it was found to be easy to insert and highly satisfactory in use, when compared to the current catheter type, with three widely spaced lateral eyes. It is hoped that the close spacing of the eyes will eliminate the complication of multicompartment block, as seen with earlier multihole catheters, and improve the safety of epidural block.
