The effect of the short-acting barbiturate enibomal (Narcodorm) on systolic time intervals.
The systolic time intervals were studied in 16 surgical patients without heart disease between 29 and 75 years of age by a non-invasive technique before and after an induction dose of enibomal (Narcodorm). The pre-injection period/left ventricular ejection time-ratio (PEP/LVET-ratio) increased between 8 and 60% and (1/PEP-2) decreased between 3 and 50%, indicating a reduction of myocardial contractility under the influence of enibomal. Factors responsible for circulatory depression during barbiturate anaesthesia are discussed.

Electroencephalographic activity in children under enflurane anesthesia.
EEG, end-tidal CO2, neck muscle EMG, eye movements, and ECG were recorded in 17 children undergoing enflurane anesthesia combined with N2O and O2. All subjects were classified in the lowest risk group and had normal pre-anesthetic EEG recordings. Eleven subjects were breathing spontaneously and six were under controlled ventilation. ⋯ At 3% enflurane, three out of eight subjects showed electrographic seizure activity of poly-spike-suppression type. One of these children also had motor manifestations during this type of seizure activity at a PaCO2 of 31 mmHg. The results indicate that electrographic seizure activity is common among children with moderate hypocapnia at enflurane concentrations of 3% or more.
