Comparison of the Effects of Halothane, Isoflurane, and Sevoflurane on Atrioventricular Conduction Times in Pentobarbital-Anesthetized Dogs

Propofol compared with sevoflurane general anaesthesia is associated with decreased delayed neurocognitive recovery in older adults

“…Sevoflurane does not sensitise myocardium to catecholamines 51 and has little effect on the cardiac conduction system. 52 However, there are reports of sevoflurane-induced arrhythmia during anaesthesia. 53,54 It is also possible that this was a spurious finding.…”

Sevoflurane as a sole anaesthetic for thymectomy in myasthenia gravis

“…MG patients are resistant to succinylcholine, which sometimes may be associated with early onset of phase II block ( 4). Furthermore, these patients have marked sensitivity to non‐depolarizing muscle relaxants, though vecuronium and atracurium have been used in very small dosages ( 6–9) (1/20th of the usual dose). As sedation is usually avoided for its additional depressant effect on respiration, verbal assurance reduces anxiety and fear of operation.…”

“…Low blood gas solubility coefficient, same uptake and elimination kinetics of sevoflurane in all age groups, good muscle relaxant property, non alteration of a–v conduction time and precise and rapid adjustment of anaesthetic depth can make this drug suitable as the sole induction and maintenance agent in cases of short duration of surgery where muscle relaxants are best avoided ( 7–10).…”

Cardiac rhythm and left ventricular function of infants at 1 MAC sevoflurane and halothane

“…Halothane has been shown to induce at different degrees, depression of sinus node function and prolongation of the atrioventricular conduction time (21,22). Although sevoflurane has been shown experimentally not to affect the cardiac conduction system (23), reports about the significant bradycardia and cardiac conduction abnormalities observed during slow‐ or high‐concentration sevoflurane induction technique of anesthesia in children suggest that sevoflurane does exert a depressive effect on the conduction system (12,24). Nevertheless, this phenomenon may have been neglected since it has been reported to be transient and in daily routine practice, inhalation induction of anesthesia is often started before applying any cardiovascular monitoring.…”
