Relief of injection pain in adults. EMLA cream for 5 minutes before venepuncture.

The effectiveness of skin anaesthesia after 5 minutes' topical application of a lignocaine-prilocaine cream was evaluated. One hundred and twenty patients estimated the pain of antecubital venepuncture both on a linear scale and verbally after use of the cream for either 5 or 60 minutes, a placebo cream or no treatment. Reported pain was significantly less after only 5 minutes of the lignocaine-prilocaine cream (p = 0.002). The cream can be used to relieve the pain of all routine injections.

Resistance of Heidbrink-type expiratory valves.

The minimum resistance of expiratory Heidbrink-type value has been assessed by determining the pressure decrease across the values at a flow rate of 30 litre min--1. The average resistance of 70 valves currently in clinical use was 318 Pa at that flow rate and about 44% had resistances greater than the limit of 294 Pa previously suggested. The resistances obtained in new valves were either similar or fractionally greater. Valves being introduced as parts of scavenging systems appeared, on the whole, to have lower resistances.
