Abstract:
Even though several studies have demonstrated the effectiveness of opioid free anesthesia (OFA) strategies in pediatric patients, OFA has not been studied in pediatric renal surgery. We, therefore, conducted a prospective observational pilot study on a total of 26 children to assess the feasibility and efficacy of using a single injection ultrasound-guided paravertebral block (PVB) at T10 level with 0.4 mL/kg bupivacaine 0.25% in combination with sevoflurane as an OFA technique in elective open renal surgery. A successful PVB (defined in terms of both hemodynamic change after the skin incision and the use of rescue analgesia) was observed in 25 children (96%). The interval between PVB and skin incision was 21 min [IQR (18-25)]. End tidal sevoflurane concentration was 2.1% [IQR (1.8-2.4)]. The median time between extubation and waking was 2.5 min [IQR (1-4)]. The median Face, Legs, Activity, cry, Consolability score in post-anesthesia care unit was 1.00 [IQR (0-2)]. Blood pressure falls were not significant at different measurement times. None of the patients had complications related to PVB, and only one patient had post-operative vomiting. PVB is an attractive method that can procure an effective OFA in combination with sevoflurane in pediatric renal surgery.
