Case Reports
[Anesthesia and intensive care management of severely burned children of Jehovah's Witnesses].
A 3.5-year-old girl suffered from a thermal injury affecting 37% of the body surface area. The parents, being Jehovah's witnesses, refused permission for their child to receive blood transfusions. As the haemoglobin level was only 7.5% and a necrectomy was planned, the patient was likely to need blood transfusions. ⋯ The lowest Hb was 3.3 g/dl on the 22th day after injury (3rd postoperative day). In this phase the patient was still playing and riding a tricycle. On the 45th day after injury the child was discharged home with Hb of 10.9 g/dl and reticulocytosis of 33%.

Biography Historical Article
[Early contributions from Erlangen to the theory and practice of ether and chloroform anesthesia. 1. Heyfelder's clinical trial with ether and chloroform].
The era of modern anaesthesia in Germany began on January 24th, 1847. This day, professor in ordinary Johann Ferdinand Heyfelder anaesthetized a patient with sulphuric ether in the clinic of surgery and ophthalmology of the University of Erlangen. By March 17th, 1847, Heyfelder had performed 121 surgical procedures under ether. ⋯ Moreover its application was much easier for it needed no special apparatus. However, because of its great anaesthetic potency, Heyfelder particularly demanded great caution in the application of chloroform. Explicitely he expected an assistant for chloroformizations, whose only duty was to supervise the inhalations and the patient--a forerunner of the modern specialized anaesthesiologist.

The on-scene performance during all missions of the emergency physician-operated rescue helicopter and mobile intensive care unit based at a large-city hospital over a period of 1 year was retrospectively analysed; 2,254 hospital discharge reports were available (92% of the patients treated by the emergency physicians [n = 2,493]). The following parameters were investigated: reliability of the primary diagnosis established by the emergency physician (by comparison with the discharge diagnoses); initial on-scene therapeutic measures; means of transportation (with or without accompanying emergency physician); and level of care of the target hospital. ⋯ In the context of quality management measures, a careful evaluation of on-scene diagnoses, therapeutic measures, and decisions made by the emergency physician is a suitable procedure for identifying systematic errors. A high percentage of correct diagnoses and therapy at the emergency site can only be ensured by clinically experienced physicians who constantly deal with patients with acutely life-threatening conditions.

Sevoflurane breaks down in basic environments to form a vinyl ether known as Compound A. This compound is toxic in the rat, with an LC50 of about 400 ppm after 3 h exposure and with renal damage evident between 50 and 100 ppm. There is no valid current evidence that Compound A is toxic in man, and the rat may not be an appropriate model for determination of this breakdown product's toxic potential in humans. The main factors influencing the degree of patient exposure to Compound A include fresh gas flow, sevoflurane concentrations, absorber temperature and composition, and the patient's carbon dioxide production.
