RESUMO
BACKGROUND AND OBJECTIVES: An optimal scoring system for pain assessment in pediatric intensive care is necessary to determine the efficacy of analgesics. We assess the COMFORT scale in postoperative ventilated children and study the effect of pain and sedation protocols on their outcomes. PATIENTS AND METHODS: We included postoperative ventilated patients. The unit-based pain management protocol was used. The assessment of the COMFORT and FLACC scales was performed by 2-nurses at 2-h intervals on the day of surgery and at 4-h intervals during the first 2-postoperative days or until the patient was ex-tubated. The patients' outcomes were compared with age-matched and RACHS score matched patients prior to the application of the pain protocol. RESULTS: One-hundred-ten prospective patients were included. The mean age and weight was 24 months and 9.8 ± 8.4 kg, respectively. There was a weak, statistically significant correlation between the COMFORT and FLACC scales, with a range of (r = 0.01-0.7). The COMFORT scale demonstrated good internal consistency, with a Cronbach's alpha of 0.75. The mean ventilation days were 1.3 ± 3, with a mean ICU and hospital stay of 5 ± 5 and 10 ± 9 days, respectively. The 110 patients were compared to 50 retrospective matching patients. The prospective group demonstrated statistically less ventilation days, ICU stay time and hospital stay time, with P-values of 0.0004, 0.001 and 0.0003, respectively. CONCLUSION: The COMFORT scale is a valuable and reliable pain assessment tool for use in postoperative ventilated pediatric patients. The implementation of a pain and sedation protocol decreased the incidence of withdrawal and the duration of mechanical ventilation as well as ICU and hospital stays.
