Anaesthesiologie und Reanimation

The postoperative care of patients usually is characterized by the fact that the individual need of pain killers is not sufficiently recognized. An opioid given only when asked for, results in an underdosage as the patient does not receive the analgesic in time, so that he suffers pain. As there is insufficient knowledge with regard to the pharmacology of opioids which can be used for postoperative pain therapy, physicians and nurses usually tend to give a lower dose in order to avoid any possible side-effects. ⋯ Piritramide has a fast onset of action, 2-5 minutes after intravenous injection and a peak action after 10 minutes. In comparison to pethidine it has no cardiovascular effects, in particular no myocardial depression or increased myocardial oxygen demand (MVO2). Last but not least, the cost-effectiveness is a financial factor of increasing importance to the institution that runs the hospital.

Historical Article[The history of the Society for Anesthesiology and Intensive Therapy of the DDR].
In 1960 the first joined meeting of East German anaesthetists took place and in 1964 the "Society of Anaesthesiology and Intensive Therapy of the German Democratic Republic" was founded. Up to its dissolution 26 years later and the 23rd of October 1990, ten congresses with international participation, 10 workshops an 5 bilateral symposia were held. The activities of the board were supplemented by 11 special working-groups. ⋯ In 1989 the "Society of Anaesthesiology and Intensive Therapy of the German Democratic Republic" hat 2,201 members including 1,327 anaesthetists. The former members of the "Society of Anaesthesiology and Intensive Therapy of the German Democratic Republic" are now joining the "German Society of Anaesthesiology and Intensive Medicine". As far as future activities are concerned, the traditional relations with the East European neighbour societies should be given special attention.

[A computer-controlled closed circle system for ventilation during anesthesia and intensive care and its possibilities for patient monitoring].
A computer feed back controlled anaesthesia- and intensive care ventilator has been developed with on-line and separate lung function measurement. The system design is built on the principle of a totally closed circuit (closed rebreathing respirometer) and an inspiratory "high flow", the gas being rotated through the closed circuit unidirectionally by a blower with 70 l/min. Ventilation is performed by metal membranes freely movable in membrane chambers with an internal part included into the closed circuit and an external part connected to pressurized air controlling inspiratory valves expiratory valves. ⋯ Ergonometric aspects led to the triangular from of the new anaesthesia and intensive care ventilator with the controlling service screen turnable to all three sides of the ventilator (high flexibility of the user) and all necessary equipment and material included into the "Anaesthesia workstation". All measured and present parameters are continuously displayed on the service (computer) screen and entered into the computer-memory in minute cycles with a memory capacity of 75 h anaesthesia. At any desired moment the memorized values can be transferred to IBM-compatible disc systems for storage or into the respective data management systems, thus at the end of anaesthesia, at the end of the working day or at the end of the week.

[An attempt at a mathematical prediction of the depth of insertion of the needle in peridural anesthesia].
The purpose of the investigation was to correlate the distance from the skin to the flaval ligament with the individual data of patients such as bodyweight, height, sex and age with the aim of predicting the depth of insertion of the needle. In a retrospective study we examined 448 patients (217 men and 231 women). In the anaesthetic records the depth of insertion of the needle was noted together with the patients' personal data. ⋯ With these formulae a rough prediction for the depth of insertion can be made, with x representing the bodyweight and y the expected depth in cm. The measured values fluctuated between 3.5 and 7.4 cm in the 217 men, with the medium value at 4.08 cm. In the 231 women the measured values fluctuated between 3.3 and 6.9 cm with the medium value at 4.67 cm.
