3 What do we know? Fasting is required ASA: 2 hr for clear fluids BCCH Anesthesia: 2 hrs Pre-operative phone call protocol is 3 hrs OR has a dynamic schedule Excessive fasting is not benign

4 Prolonged Fluid Fasting Why does it matter? Physiological impact Dehydration Hypoglycemia Hypotension Psychological impact Patients 1-4 Parents 1 Benchmark quality indicator: 2-3 hrs UK RCoA & APAGBI 1 Pediatr Anesth 2011;21: Anesth Analg 2001;93: AJN 2011;111: Nursing Children and Young People 2011;23:14-19

5 Study Purpose What is the current “state of play”? Assess actual clear fluid fasting times for our patients

6 Methodology Inclusion Criteria June 14 - July 13, 2012 age 0 – 17 yrs received SDCU pre-op fasting instructions returned to SDCU during JC’s work hours Fasting time = procedure room entry - last reported clear fluid intake time > 4h interval = “over-fasted”

7 Results n = 416 n = 214 Median: 3:29 IQR: 2:58 – 4:17 n = 202 Median: 12:36 IQR: 11:11 – 14:13

8 Age n = 398 n = 18

9 Infants n = 18

10 Patients 1 – 17 Years n = 398

11 Age Distribution n = 260

12 Time of Day Scheduled OR n = 297 n = 101

13 Morning n = 297 n = 145 Median: 3:20 IQR: 2:51–4:03 n = 152 Median: 11:50 IQR: 10:54–13:13

14 Afternoon n = 101 n = 51 Median: 3:36 IQR: 3:11-4:21 n = 50 Median: 14:54 IQR: 13:30–16:36

15 Summary of Results Bimodal distribution 1 st peak:3.5 hrs; 50% population 2 nd peak:12.5 hrs; 50% population 65% clear fluid fast >4 hrs Patients <3 yrs are most challenging Not uncommon results

16 Reasons For Findings? Parental parents’ historical experience w anesthesia tend towards ‘over-compliance’ 3,4 Healthcare fear of over-complicating instructions maximising OR flexibility 5 outdated concerns re fasting & aspiration risk 3 3 AJN 2011;111: Nursing Children and Young People 2011;23: J. Clin. Anesth 2000;12:48-51

17 Implications for Practice Change conversation in phone room different education? prescribed fluid time? Case by case discussion Establish benchmarks for ongoing audit

18 Conclusions Two thirds of patients experience prolonged fasting 30% < 3yr Literature suggests specific actions to mitigate Practice change will take effort Auditing needs to be continued on an ongoing basis
