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%.

[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.

The inhalational anaesthetic fluor-methyl-trifluor-1-(trifluoromethyl)-ethylether sevoflurane has been known for more than 20 years and is structurally related to the currently available volatile anaesthetics. This anaesthetic is characterized by a low blood/gas partition coefficient of 0.69 and high fat solubility, leading to a sharp rise in alveolar concentration and quick anaesthesia induction. As opposed to desflurane, sevoflurane does not boil at ambient temperature, thus making a special vaporizer unnecessary. ⋯ As opposed to methoxyflurane, which may be nephrotoxic due to its microsomal metabolism in kidney tissue, sevoflurane does not seem to cause clinical inhibition of renal function even at plasma fluoride levels above 50 mumol/l, a concentration thought to be associated with renal tubular impairment. A possible reason for this observation is lower metabolism of sevoflurane within renal tissues. Due to its quick onset and fast elimination, sevoflurane is an interesting new volatile anaesthetic offering various clinical advantages.

[Treatment reduction in intensive care. "Allowing the patient to die" by conscious withdrawal of medical procedures].
The conversion of an "attempt to treat" to "prolongation of dying" represents an important problem in modern intensive care. If the actual or presumed will of the patient is unknown, the physician has to decide about the extent of treatment in a paternalistic manner. In these difficult decisions the physician has to consider prognosis, and certainty of prognosis and has to carefully balance between the right to live and the right to die. ⋯ If the situation is hopeless and further medical interventions are futile, then allowing the patient to die by therapy reductions is not only a possibility but a mandatory act of humanity. In that case it does not matter whether new treatment modalities are abandoned or whether already instituted medical measures are withdrawn. In clinical practice, however, the "fine tuning" of therapy reduction has to be tailored to the individual case and largely depends on prognostic certainty.
