Abstract:
Background: After institutional approval and parental consent, 103 children, aged 6 months to 18 years, who were undergoing repair of simple and complex congenital heart lesions using cardiopulmonary bypass (CPB) were studied and compared with a group of 135 children who had undergone similar surgery in our institution in the year before. Methods: Anaesthesia for study patients included fentanyl (< 20 μg·kg−1) and isoflurane. Infusions of propofol (median infusion rate 70 μg·kg−1·min−1) and morphine (median infusion rate 20 μg·kg−1·h−1) were started after weaning from CPB and continued postoperatively. Preestablished criteria were used in the intensive care unit (ICU) to assess readiness for tracheal extubation. Results: Median time from admission to ICU to tracheal extubation was 5 h. Fifty-six children were extubated within 6 h and 73 within 9 h of ICU admission. Mean ICU stay for study patients was 1.7 days [95% confidence interval (CI) 1.2-2.2] and 2.6 days (95% CI 2.3-2.9) in the comparison group (P<0.005). Conclusions: We found the propofol regimen to be satisfactory with a shorted ICU stay for these patients.Keywords: sedation; propofol; intensive care unit: paediatric; heart surgery
