The effect of artificial ventilation, apnea, and norepinephrine administration on heart rate variability was determined in brain-damaged rabbits. Electrocardiographic R-R intervals and circulatory variables were measured for 5 min at three different ventilatory frequencies, including apnea under isoflurane general anesthesia. The same measurements were repeated after brain damage was inflicted by an inflated intracranial balloon. In control rabbits (n = 8) and in those receiving norepinephrine (n = 8), power spectral analysis of R-R intervals was repeated, and spectral components of low (LF: 0.04-0.09 Hz), mid (MF: 0.09-0.15 Hz), and high (HF: 0.15-0.40 Hz) frequency band areas were assessed. LF + MF (P < 0.05) increased during apnea, whereas HF did not change under general anesthesia. However, after brain damage in both groups LF + MF did not change, whereas HF was depressed (P < 0.05). There was no intergroup difference in decreases of HF/(LF + MF) (P < 0.05) during apnea under either condition. Norepinephrine increased heart rate and arterial pressure (P < 0.05) but did not produce any intergroup difference in the spectral components. We suggest that sympathovagal balance is apt to be sympathotonic during apnea under general anesthesia, whereas it is vagolytic with brain damage.

Abstract. In the environment of anesthesia, good performance describes the absence of threat for the patient as well as a quick reaction to challenging and possibly life-threatening circumstances. Elsewhere, performance and cognitive function have been linked to indicators of vagally-mediated heart rate variability (HRV). This exploratory study examines the correlation between anesthetists’ HRV and their performance during uneventful induction of general anesthesia and during a simulated critical incident. For this study electrocardiograms (ECG) were obtained from two different groups of anesthetists providing general anesthesia in uneventful real cases in the operation room (OR, n = 38) and during the management of a hypotension scenario in a high-fidelity human patient simulator environment (SIM, n = 23). Frequency, time domain, and nonlinear HRV metrics were calculated from 5-min ECG recordings. To separate high performing (HP) and low performing (LP) individuals, the time needed for induction (in the OR setting) and the length and depth of hypotension (in the SIM setting) were used as performance correlates. The Mann-Whitney- U-test was used to assess differences in HRV within the groups. In both settings (OR and SIM), linear and nonlinear HRV metrics did not differ significantly between the HP and LP group. Also, the anesthetists’ work experience and sex were not related to performance. While providing general anesthesia and during a simulated critical incident, high and low performing individuals do not differ with respect to HRV metrics, sex, and work experience. Further research including the HRV under resting conditions is necessary.
