Catheter Redosing of Autonomic Neural Blockade After Sleeve Gastrectomy

NCT07655908 · Status: NOT_YET_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

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.

Conditions

  • Pain, Acute Post-Operative
  • Nausea and Vomiting, Postoperative

Interventions

OTHER

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
