[Effect of subpartal tocolysis on maternal cardiovascular parameters with subsequent cesarean section in general anesthesia].
The influence of subpartal beta-sympathicomimetic tocolysis on a subsequent Caesarean section with halothane as inhalational anaesthetic was examined in 42 pregnant women. Alterations in the heart rate, blood pressure and heart action during the operation were measured. 23 patients (group "bolus") received fenoterol monotherapy. In 19 patients (group "iv-tocolysis") fenoterol was combined with the cardioselective beta-1-blocking agent metoprolol. ⋯ Arrhythmias of ectopic origin and sinus bradycardias, however, were found seldom. The incidence of arrhythmias in the three groups during Caesarean section did not differ significantly. There was no evidence for an increased occurrence of arrhythmias following beta-sympathicomimetic tocolysis.

[Respiratory minute volumes following end expiratory CO2 values in artificial respiration in anesthesia].
During artificial ventilation of anaesthetised patients the respiratory minute volumes were estimated after end tidal CO2-values (eeCO2) and correlated to arterial blood gases. In men the mean respiratory minute volume of 130 ml/kg body weight (b.w.) was significantly above the 113 ml/kg b.w. of women. 9.7-year-old boys and 16-year-old men had higher minute volumes (178 ml/kg b.w. and 148 ml/kg b.w. respectively) in comparison to men of 23 years of age. In contrast, no significant difference was seen in the older age groups. ⋯ EeCO2-values of 3.8 to 4.2 per cent by volume stand for a very marked hyperventilation in the pulmonary healthy patient. The arterial alveolar difference of the CO2 pressure (aADCO2) was in the normal range between 1 and 5 mmHg. The end tidal CO2 estimation is a noninvasive and suitable method to exactly meet the ventilatory needs of the anaesthetised patient.

Randomized Controlled Trial Clinical TrialPrevention of peroperative hypothermia in abdominal surgery.
It is important to reduce or prevent heat loss during anaesthesia, especially in patients with restricted cardiopulmonary reserves. To test a specially developed esophageal thermal tube (GK-esophageal thermal tube) for this purpose, 33 patients were randomly divided into two groups: Group A were given heat transferred to the central core during operation, using the GK-tube with circulating 41.7 degrees C warm water. Group B received no active warming. ⋯ The described method was easy to use and without complications. We recommend this method to prevent peroperative hypothermia in all patients suspected to have limited cardiopulmonary reserves. The possible hazards and how to avoid these are described.
