During the last 30 years a great number of case reports presented severe anaesthetic complications with sudden cardiac arrest in patients with muscular dystrophies, mostly unsuspected at the time of the event. As succinylcholine was involved in the majority of the intractable incidents with lethal outcome the Food and Drug Administration (FDA) of the United States recommended a warning of the administration of succinylcholine in young children and adolescents in 1992 and an extensive international discussion on the routine use of succinylcholine in paediatric anaesthesia. Epidemiological studies on this issue are rare. We projected an inquiry about the incidence rate and type of severe anaesthetic complications in an utmost large number of patients and families with Duchenne (DMD) and Becker type (BMD) muscular dystrophy. ⋯ Our results demonstrate that severe incidents and cardiac arrests occurred only in young children with undiagnosed DMD or BMD who received inhalational agents and succinylcholine. A cardiac arrest in 6 out of 200 families was found much more frequently than in the normal paediatric population (about 1:1000 to 1:3000). The decrease of events after 1992 (warning of the FDA) and disappearance of sudden cardiac arrests in our group of patients might be due to the world wide discussion on routine use of succinylcholine in children or the much earlier establishment of the diagnosis in our population. An early diagnosis of DMD and BMD and the avoidance of the triggering agents succinylcholine and volatile anaesthetics can reduce the risk of severe anaesthetic complications.

The objective of this review is to describe which hygiene measures are appropriate and necessary in anaesthesia and the ICU and which are not, whereby unnecessary hygiene measures are those which are not substantiated by scientific data. The most effective single infection control measure is still hand disinfection between patient contacts. Unnecessary measures include routine sampling of environmental surfaces, disinfecting the floor in the ICU, protective gowns for visitors, so called in-line filters in the infusion system etc. Ventilator tubes only need to be exchanged once a week, even when no HMEs are used.

Randomized Controlled Trial Clinical Trial
[The effect of different priming doses on the pharmacodynamics of cisatracurium].
The aim of the study was to evaluate the effect of two different priming regimen on the onset time of 100 micrograms/kg cisatracurium, when compared to bolus administration. ⋯ Our data indicate that the "priming principle" is an appropriate technique to shorten the onset time of cisatracurium. To achieve a maximum effect the priming combination of 15 micrograms/kg cisatracurium followed after 4 min by 85 micrograms/kg cisatracurium is recommended.
