Postoperative analgesia in children using preemptive retrobulbar block and local anesthetic infiltration in
Insights
Regional anesthesia techniques like retrobulbar block and local infiltration did not significantly improve postoperative pain management in pediatric strabismus surgery compared to no block. Conventional pain relief methods appear adequate for these patients.
Area of Science:
- Ophthalmology
- Anesthesiology
- Pediatric Surgery
Background:
- Postoperative pain management in pediatric strabismus surgery is understudied.
- Effective pain control can facilitate earlier patient mobilization.
- Regional anesthesia techniques are explored for improved outcomes.
Purpose of the Study:
- To compare the efficacy of retrobulbar block and local infiltration versus no block for postoperative pain management in pediatric strabismus surgery.
- To evaluate pain scores, analgesic requirements, and other recovery parameters.
Main Methods:
- Thirty pediatric patients undergoing strabismus surgery were randomized into three groups: control (no block), retrobulbar block, and subconjunctival bupivacaine infiltration.
- Pain was assessed using Visual Analog Scale (VAS) and Modified Pediatric Objective Pain Scale (MPOPS).
- Circulatory status, nausea, vomiting, analgesic use, sleep, activity, and appetite were monitored in the early and late postoperative periods.
Main Results:
- The subconjunctival bupivacaine infiltration group showed significantly higher pain scores at multiple time points compared to the control and retrobulbar block groups.
- The retrobulbar block group experienced a non-significant trend towards increased nausea and vomiting but required less analgesia post-discharge.
- Improved late postoperative activity and appetite were noted in both regional anesthesia groups compared to the control.
Conclusions:
- Neither retrobulbar block nor subconjunctival local anesthetic infiltration provided significant postoperative analgesia benefits over the control group in pediatric strabismus surgery.
- Conventional pain management strategies are considered adequate for postoperative care in this patient population.
- Further research may be needed to explore alternative or refined regional anesthetic techniques.
Background And Objectives:
Postoperative pain management in pediatric strabismus patients is infrequently studied. Pediatric patients can be mobilized earlier if postoperative pain is minimized. In this study, two different regional anesthetic techniques, retrobulbar block and local infiltration, were compared with a "no block" control group for the postoperative management of pain in pediatric patients undergoing elective strabismus surgery.
Methods:
Thirty patients were randomly allocated to one of the study groups: group 1 (n=10) control, group 2 (n=10) retrobulbar block, and group 3 (n=10) subconjunctival bupivacaine infiltration. The parameters that were evaluated during the early postoperative period (6 hours) were circulatory, pain scores by Visual Analog Scale (VAS) and Modified Pediatric Objective Pain Scale (MPOPS), additional analgesic requirement, nausea, and vomiting. The parameters that were evaluated after discharge from the hospital (on postoperative days 1 and 2) through questionnaires were additional analgesic requirement, nausea, vomiting, sleep disturbances, activity, and appetite.
Results:
Group 3 had significantly higher VAS and MPOPS scores at postoperative 120, 180, 240, 300, and 360 minutes than groups 1 and 2 (P < .05). Patients in group 2 seemed to have a higher incidence of nausea and vomiting both in the early (6 hours) and late postoperative (postoperative days 1 and 2) periods; however, the difference was not statistically significant. Group 2 required less analgesic compared with groups 1 and 3 during the late postoperative period. Late postoperative activity and appetite were better in groups 2 and 3.
Conclusions:
Because there was no significant difference in terms of postoperative analgesia in the retrobulbar block or subconjunctival local anesthetic infiltration groups compared with the control group, we suggest that conventional methods of pain treatment are adequate for postoperative analgesia in strabismus surgery.
