Anaesthetic management of abdominal hysterectomy in patient with congenital sinus node dysfunction
Journal of the College of Physicians and Surgeons
A 45 years old woman having dysfunctional uterine bleeding was scheduled for total abdominal hysterectomy with bilateral salpingo-oophorectomy under general anaesthesia. On pre-operative anaesthesia assessment, she was found to have junctional rhythm at rate of 44 beats/minute with bigeminies and pre-mature ventricular contractions on ECG. On further evaluation, she was diagnosed as having congenital sinus node dysfunction on the basis of 24 hours Holter monitoring. She was asymptomatic, no
... symptomatic, no prior comorbidity and belonged to functional class one. General anaesthesia was successfully managed by vigilance, invasive monitoring, standby transcutaneous and transvenous pacemakers; use of cardiostable and vagolytic anaesthetic agents like Etomidate, Atracurium and Pethidine during the procedure and for postoperative pain management. Transcutaneous external pacing pads were placed just after induction of anaesthesia, their functional apability was confirmed and was ready for use if needed. The transcutaneous and transvenous pacemakers were on backup and both were not required. Patient was successfully managed and was discharged home on third postoperative day with uneventful hospital course. The elective pacemaker implantation was therefore not required.
