Risk Recognition and Multidisciplinary Approach for Non-Cardiac Surgeries in Paediatric Cardiac Patients: A Retrospective Observational Study

Background Congenital heart disease (CHD), a structural and functional heart disease, is the commonest birth defect with an incidence of one in 125 live births worldwide with ventricular septal defect (VSD), atrial septal defect (ASD) and tetralogy of Fallot (TOF) constituting the majority. Surgery for associated extra-cardiac anomalies (airway, skeletal, genitourinary, and gastrointestinal) may be required in 30% of these patients. Delivery of uneventful anaesthesia in these children requires an understanding of not only paediatric anaesthesia but also of the pathophysiology of the cardiac lesion and its associated risks. Aims The purpose of this retrospective review was to highlight the approach to the anaesthetic management and outcomes of patients with significant cardiac lesions presenting for non-cardiac surgeries. Material and methods A retrospective chart review of all children with congenital heart disease (CHD) (repaired or unrepaired) who were posted for a non-cardiac surgery in this tertiary care Paediatric super-specialty hospital from January 1, 2018 to December 31, 2019 was carried out. Data on demographics, peri-operative management, and clinical course was retrieved. Inclusion criteria were paediatric patients (0-18 years) of either gender with a diagnosis of a CHD (repaired or unrepaired) undergoing any non-cardiac surgeries (NCS) under anaesthesia/Monitored Anaesthesia Care (MAC). Exclusion criteria were procedures only under local anaesthesia (LA) or a minor procedure done solely under sedation not involving an anaesthesiologist. Results During the study period, we found five eligible cases who underwent a total of six procedures. Five procedures were elective and one was an emergency. Preoperative optimization was conducted by a multidisciplinary team including paediatric surgeons, anaesthesiologists, physicians, and cardio-thoracic surgeons. Anaesthesia was conducted by at least a consultant paediatric anaesthesiologist. Overall all patients tolerated anaesthesia well without any adverse events or complications. All six anaesthetic encounters were safe and uneventful.
