Abstract

Introduction Guidelines existed at the Royal Children’s Hospital (RCH) to direct preoperative/pre-procedural fasting in day patients undergoing general anaesthetic. However audit, risk analyses and a recent research project at the RCH identified prolonged pre-procedural fasting times in children undergoing day surgical and gastroenterology procedures.

Aims 1. Reduce median fasting time to <8 hrs for children admitted for a day procedure under general anaesthetic; 2. Identify children at risk of perioperative hypoglycaemia.

Methods The study was conducted in 4 phases: 1) revision and implementation of evidence-based perioperative fasting guidelines with staff education relating to these guidelines; 2) cross-sectional descriptive study with day surgical patients (n = 377) requiring preoperative fasting. ‘Normal risk’ and ‘High risk’ groups were identified for fasting hypoglycaemia using an ‘at risk’ checklist. Venous blood glucose (BGL) testing was performed at a) anaesthetic induction; b) prior to first caloric food/fluid postoperatively; 3) chart audit to evaluate efficacy of guidelines and parent information; 4) development of recommendations for clinical practice.

Results The median fasting time for children having morning surgery (14 hrs, IQ range 5–22 hrs) was twice as long compared to afternoon lists (7 hrs, IQ range 6–22 hrs) (p < 0.001). Median fasting times were not significantly different between ‘at risk’ and control groups (p = 0.496). However the proportion of children who experienced hypoglycaemia (BGL <3 mmol/L) was greater in the ‘at risk’ group (5, 8%) compared to the control group (18, 4.3%). Although not statistically significant (x2 = 2.254, p = 0.133), ‘at risk’ children appear more likely to experience hypoglycaemia as children in the control group, constituting a clinically significant finding.

Conclusion Appropriate identification and management of ‘high risk’ children, will reduce the risk of deleterious sequelae in children undergoing surgical or investigative procedures requiring general anaesthesia.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
