Unlabelled:
The objectives of this study were to verify the frequency of pharmacological analgesia and the occurrence of postoperative pain in neonates undergoing cardiac surgery.
Methods:
This is a cross-sectional study and data were collected from 30 medical charts of neonates who underwent cardiac surgery in a private hospital in the city of São Paulo.
Results:
The majority (96.6%) of neonates received analgesia: 18 (60.0%) received continuous analgesics, five (16.7%) received intermittent drugs, and six (20.0%) received a combination of continuous and intermittent analgesics. Fentanyl citrate was continuously administered to 24 (80.0%) neonates. Intermittent dipyrone and morphine was administered to ten (33.3%) and one (3.3%) neonates, respectively. Pain registers were observed in 17 (56.7%) medical charts and the occurrence of pain among neonates who received analgesics was 53.4%.
Conclusion:
There was no efficacy in pharmacological postoperative pain control in the neonates included in this study.
