Introduction: Hyperglycemia in pediatric patients has been associated with significant complications. Several studies have shown the effects of hyperglycemia as a marker for adverse outcome in post-operative pediatric cardiac patients. The main objective of this study is to determine the association of mean glucose levels in the immediate post-operative period during the 1st 24 to 72 hours on mortality and morbidity among pediatric patients following cardiac surgery.
Methods: A retrospective cohort was performed among 109 pediatric patients, less than 19 years years of age, who underwent cardiac surgery, from January 2009 to December 2009. Hospital records were reviewed. Baseline information were obtained from review of the chart. Patients were classified into risk categories according to consensus-method of risk adjustment for surgery for congenital heart disease (RACHS-1). Blood glucose levels were taken from the records from the 1st 24 and 72 hours post-operative period and operative data were obtained from the anesthesia ad operating room records.
Discussion: A total of 5 patients (4.6%) expired after surgery, while 18 patients had post-operative morbidities. Younger age, higher RACH score, prolonged hospital stay and PICU stay; and longer bypass and cross clamp time were all associated with morbidity. Both mean glucose and peak glucose levels were associated with mortality.
Conclusion: This study described the association of hyperglycemia with mortality after cardiac surgery. There were significant differences in the mean and peak glucose levels during the 1st 24 hours in terms mortality.
