Postoperative Analgesia for Pediatric Craniotomy Patients: A Randomized Controlled Trial
Abstract Background: Pain is often observed in pediatric patients after craniotomy procedures, which could lead to some serious postoperative complications. However, the optimal formula for postoperative analgesia for pediatric neurosurgery has not been well established. This study aimed to explore the optimal options and formulas for postoperative analgesia in pediatric neurosurgery. Methods: Three hundred and twenty patients aged 1 to 12-years old who underwent craniotomy were randomly assigned to receive 4 different regimens of patient-controlled analgesia (PCIA or NCIA). Postoperative pain scores at different time point after surgery and analgesia-related complication were recorded respectively. Comparative analysis was performed between the four groups. Results: In all groups, significantly lower pain scores were observed at one to 8 hours in the morphine group (P<0.05). There was no significant difference in pain scores between the fentanyl and tramadol groups (P>0.05), both of which had lower pain scores than the placebo group (P<0.05). However, a higher incidence of nausea and vomiting occurred in the tramadol group during the 48 hours of NCIA usage after operation (P=0.020). Much more rescue medicines including ibuprofen and morphine were used in control group (CI=0.000-0.019). No consciousness change and respiratory depression was observed in all groups. There were 56 children experienced moderate-severe pain(17.5%), younger children (OR=1.161, 1.027-1.312, P=0.017), occipital craniotomy (OR=0.374, 0.155-0.905, P=0.029), morphine treatment, were relevant factors of moderate-severe pain in pediatric patients. Conclusions: Compared with other analgesic projects, PCIA or NCIA analgesia with morphine appears to be the safest and most effective postoperative analgesia program for pediatric patients who underwent neurosurgical operations.
