Background: Sevoflurane has been used to induce anaesthesia in adults due to its suitability for airway management and haemodynamic stability. Few studies have reported arrhythmia during volatile induction with sevoflurane in adults. Here, we investigated the incidence of arrhythmia and risk factors associated with its occurrence during sevoflurane induction of anaesthesia in adults.

Patients And Methods: We retrospectively analysed 950 adult patients who underwent elective ear nose and throat surgery with volatile induction using sevoflurane between May and December 2015. The incidence of arrhythmia and the factors associated with its development were analysed.

Results: Arrhythmia was observed in 164 (17.3%) of 950 adult patients. The most frequently observed arrhythmia was sinus tachycardia (heart rate > 120 bpm) (77 patients, 47.0%). The multivariable logistic analysis showed four independent risk factors: age (odds ratio [OR] = 0.984, 95% confidence interval [CI] = 0.973-0.996, p = 0.006), coronary artery disease (OR = 3.749, 95% CI = 1.574-8.927, p = 0.003), maximal concentration (8 vol%) of sevoflurane from the start of induction (OR = 2.696, 95% CI = 1.139-6.382, p = 0.024), and maintenance of 8 vol% sevoflurane concentration after eyelash reflex loss (OR = 1.577, 95% CI = 1.083-2.296, p = 0.018). The risk of hypotension was greater in patients in whom arrhythmia occurred, although blood pressure recovered to baseline after the concentration of sevoflurane was adjusted.

Conclusions: We recommend that the sevoflurane concentration be gradually increased with continuous and vigilant electrocardiogram and blood pressure monitoring. The sevoflurane concentration should be adjusted after sufficient unconsciousness is reached.

Effect of operative time on the outcome of patients undergoing off-pump coronary artery bypass surgery.

J Card Surg 2019 Nov 26;34(11):1220-1227. Epub 2019 Aug 26.

Background: Several studies have been reporting circadian variation in postoperative morbidity and mortality. We investigated whether the outcomes after off-pump coronary artery bypass (OPCAB) surgery are influenced by the operation start time.

Methods: We retrospectively evaluated 1690 patients who received elective OPCAB surgery from January 2006 to December 2016. The patients were divided into two groups according to the operation start time (morning or afternoon). The primary outcome was the occurrence of a major adverse cardiac event (MACE) within 30 days after surgery and death within 1 year after surgery. Propensity matching analysis and multivariable analyses were performed to evaluate the relationship between the operation start time and postoperative outcomes.

Results: There were no significant differences in the overall 1-year mortality rate (2.2% vs 2.9%; P = .568 in the entire cohort and 1.5% vs 2.7%; P = .259 in the propensity-matched cohort) and 30-day MACE rate (8.9% vs 10.4%; P = .378 in the entire cohort and 9.4% vs 10.0%; P = .827 in the propensity-matched cohort) between the morning and afternoon surgery group. Multivariable regression analyses also did not show any significant relationship between the operation start time and postoperative outcomes.

Conclusions: In elective OPCAB surgery, the operative time was not associated with an increased risk of postoperative mortality and complications.
