[Nitrous oxide in the working environment of anaesthetic personnel. A gas chromatographic analysis (author's transl)]

Nitrous oxide as well as halothane is hazardous for organ dysfunction in chronically exposed man. It is necessary for each anaesthetist, in cooperation with the hospital authorities, to take care to eliminate overflow not only of halothane but also of nitrous oxide from anaesthetia locations. Using gas chromatography, we studied the concentration of nitrous oxide during routine daily work in the environment of anaesthetic personnel. With our method of discharging anaesthetic gases, we were able to reduce the concentration of nitrous oxide.

Melanoma in a patient treated for psoriasis

Psoriasis, ultraviolet light, and coal tar have been associated with the development of cutaneous malignancy. We have described a 32-year-old psoriatic man who developed a melanoma after 16 years of treatment with ultraviolet light and coal tar. This is the only case of melanoma occurring in a patient treated for psoriasis reported in the world literature.

[Control of respirator pressure and drainage of the anesthetic gases with Kuhn's device in pediatric anesthesia (author's transl)]

By adding a manometer and a pressure valve to the anaesthetic equipment used for newborns and children (Ayre-T-piece, modified by Kuhn) we are able to control airway pressures continuously and to draw out all narcotic gases from the operating room. The concentration of halothanee thus can be diminished to a very low level around the aneasthesist and the surgeon.

[The concentrations of halothane in the operating theatre and its dependance on various methods of removal (author's transl)]

Measurement of halothane concentrations by means of gas chromatography was used to compare the efficiency of 1) a filtration system and 2) ducting of gases into the exhaust of the ventilation system of our operating threatre. The concentrations were found to be lower when the latter method was used. Measurements made subsequently provided data on halothane concentrations occurring during routine service when different methods of anaesthesia were used, with and without ducting of gases into the ventilation exhaust system.

Parenterale Ernährung auf einer interdisziplinären operativen Intensivpflegestation (Organisation und Praxis)

Es wird über Organisation und Praxis der parenteralen Ernährungauf einer interdisziplinären operativen Intensivpflegestation berichtet. Es werden Überlegungen zur Auswahl der Infusionslösungen, besonders der Aminosäurelösungen, geschildert. Die Bedarfsrechnung- Bilanzierung wird erläutert. Eine Bedarfstabelle wird vorgestellt.

[Intranarcotic infusion therapy -- a computer interpretation using the program package SPSS (Statistical Package for the Social Sciences)]

In a retrospective 18-month study the infusion therapy applied in a great anesthesia institute is examined. The data of the course of anesthesia recorded on magnetic tape by routine are analysed for this purpose bya computer with the statistical program SPSS. It could be proved that the behaviour of the several anesthetists is very different. Various correlations are discussed.
