Background:
An increasing embracement of safer regional techniques as pivotal components of multimodal analgesia regimen has made fast-tracking possible following pediatric cardiac surgery. Speaking of fast-tracking in pediatrics, the feasibility of on-table extubation (OTE), and its’ potential benefits are also being ardently researched with simultaneous emphasis on appropriate patient selection and adequate perioperative safety.
Case Series:
We report eight consecutive pediatric cases featuring a combination of serratus anterior plane block (SAPB) or erector spinae plane block (ESPB) to general anesthesia (GA) for patent ductus arteriosus (PDA) ligation through a left thoracotomy incision. Following induction of GA, the left-sided SAPB was performed in five patients and the other three patients received left-sided ESPB, each with 0.5 mL/kg of 0.2% ropivacaine. Demonstrating a mean intraoperative fentanyl requirement of 3.25 ± 0.71 µg/kg, OTE could be successfully contemplated in all the 8 patients. Subsequently, the post-operative face, leg, activity, cry, and consolability (FLACC) score was recorded at 1, 2, 4, 6, 8, and 12 h. Meanwhile, all the patients depicted acceptable pain scores till 4 h, administration of 0.5 µg/Kg rescue fentanyl was necessitated in three patients each at 6-h and 8-h postoperatively (given FLACC scores ≥4), amounting to a mean 0.375 ± 0.23 µg/kg post-operative fentanyl requirement. All patients received intravenous paracetamol at 8-h postoperatively. No block-related complication or need for reintubation was discovered.
Conclusion:
Incorporation of fascial plane blocks (SAPB or ESPB) to the conduct of GA for PDA ligation, allowed for safe OTE in our experience, due to an opioid-sparing potential.
