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.

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.

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.

Twenty-five patients underwent epidural anaesthesia with a new formulation of chloroprocaine 3% (1.0-1.5 ml x 10 cm body height-1) for a variety of day procedures. The mean (range) duration of surgery was 17 (5-35) min. ⋯ Two patients complained of severe backache immediately after operation and a further 16 and four patients reported mild or moderate backache respectively. Operating conditions were excellent in all but one patient and 23 patients said they would be happy to have the same anaesthetic again.

The case notes and anaesthetic charts of 44 patients with dystrophic epidermolysis bullosa were reviewed retrospectively. A total of 390 general anaesthetics were performed for 469 surgical procedures over a 10-year period. Procedures included repair of syndactyly, dilatation of oesophageal strictures, extraction of teeth, excision of skin tumours and other procedures related to dystrophic epidermolysis bullosa. ⋯ Previous reports have suggested problems with the use of suxamethonium, nondepolarising muscle relaxants and thiopentone. These agents were all used in many of our patients without any adverse effects. There was one intra-operative death in a 35-year-old woman having an oesophageal dilatation which was complicated by oesophageal rupture.
