NCT05231460

Brief Summary

This study aims to better understand the role that narcotic vs. non-narcotic multimodal pain management play in patients' pain following bariatric surgery (Laproscopic Surgery and Robotic Assisted Surgery). Participation in this study will last approximately 90 days following surgery. During that 90 day period, participants will be asked to report pain and nausea every 4 hours to a study coordinator or nurse while they are recovering in the hospital. Following discharge from the hospital patients will be asked to report pain, nausea, and any medical changes 7 days, 30 days, and 90 days from surgical date. The procedures and medications used in this study are FDA approved medical therapies and are part of Standard of Care for this population. This study aims to therapeutically investigate efficacy of the proposed pain management regimens. The procedures and individual medications are not the subject of research as they are considered routine well established and documented interventions for obesity and the treatment of post operative pain.

Outcome Measures

Primary Outcomes (1)

  • postoperative pain

    Patient reported postoperative pain using the Wong Baker Faces pain scale. The scale shows a series of six faces ranging from a happy face at 0, or "no hurt", to a crying face at 10, which represents "hurts like the worst pain imaginable. Based on the faces and written descriptions, the patient chooses the face that best describes their level of pain.

    discharge or 24 hours postoperative, whichever is first

Secondary Outcomes (4)

  • Postoperative nausea

    post-operative until patient discharge or up to 90 days, whichever comes first

  • 200 foot ambulation

    post-operative until patient discharge or up to 90 days, whichever comes first

  • Hospital length of stay

    post-operative until patient discharge or up to 90 days, whichever comes first

  • Readmissions

    up to 30-day postoperatively

Masking Details
Treating surgeon will not be blinded to randomizations. Anesthesiologist providing the Tap Block will be blinded to narcotic arm and unblinded to Tap vs No Tap. Study Coordinator will be blinded to Tap vs No Tap. Statistician will be unblinded to both groups at end of study for final analysis.
Purpose
TREATMENT
Intervention Model
FACTORIAL
Model Details: Each subject will be randomized at 1:1 ratio to receive either the Narcotic Pain Regimen or the Non-narcotic Pain Regimen and will also be randomized at 1:1 ratio to receive either TAP block or no TAP block. Eligible subjects will therefore be randomized to one of four arms with approximately equal sizes:1) narcotic regimen with TAP block; 2) narcotic regimen with no TAP block; 3) non-narcotic regimen with TAP block; 4) non-narcotic regimen with no TAP block. The primary comparison will be between narcotic and non-narcotic regimens (arms 1 and 2 combined versus arms 3 and 4 combined). Comparison of TAP block versus no TAP block (arms 1 and 3 combined versus arms 2 and 4 combined) will performed as a secondary analysis.
