Catheter Redosing of Autonomic Neural Blockade After Sleeve Gastrectomy
Sponsor: Universidad Simón Bolívar
Summary
Postoperative visceral pain and autonomic symptoms after laparoscopic sleeve gastrectomy may reappear earlier in selected high-risk patients despite standard intraoperative autonomic neural blockade (ANB). Temporary in situ catheter placement permits postoperative ANB redosing when breakthrough visceral symptoms occur. This prospective single-arm observational study will evaluate the feasibility, safety, and clinical effectiveness of temporary ANB catheter placement and selective postoperative redosing in high-risk patients undergoing laparoscopic sleeve gastrectomy.

Interventions
Bupivacaine 0.5% and Dexamethasone via Temporary Catheter
Autonomic neural blockade (ANB) re-dosing will be performed by administering bupivacaine 0.5% and dexamethasone through a temporary catheter placed in the paragastric area during laparoscopic sleeve gastrectomy
