Clinical Proposal for the Comparison of Intraperitoneal Anesthetic to Injected Local Anesthetic

May 9, 2012 updated by: Troy Moritz, D.O., Pinnacle Health System

Evaluation of Aerosolized Bupivacaine Versus Pre-incision Lidocaine Versus Instilled Liquid Bupivacaine Versus Post-operative Bupivacaine Injection for Optimization of Post-operative Pain Control in Laparoscopic Bariatric Surgical Patients

The purpose of this study is to determine if pre-incisional lidocaine injection, instilled liquid bupivacaine, intra-abdominal aerosolized bupivacaine, or post-operative bupivacaine injection is superior in post-operative pain control in laparoscopic bariatric surgical patients.

Detailed Description

The research objective is to compare our standard post-operative port site injection of 0.5% bupivacaine against pre-incisional port site injection of 1% lidocaine against the instillation of streamed bupivacaine 0.5% against the instillation of aerosolized 0.5% bupivacaine as it relates to post-operative analgesia usage and pain scale scores. The null hypothesis will be that there is no difference between the four arms of the study in regards to pain score and analgesia usage.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 2
Drug: Injected lidocaine pre-incision vs saline pre-incision
Patients will receive 30ml of 1% lidocaine divided equally and injected prior to port site incisions, then 10ml of 0.9% normal saline streamed via port directed at operative field, then 10ml of 0.9% normal saline aerosolized into the coelomic cavity prior to deflation and our current standard of care, which is 30ml of 0.5% bupivacaine, divided equally between the five port-sites, injected at the end of the operation.
Other Names:
  • normal saline
  • lidocaine
  • pre-emptive
Experimental: 3
Drug: Streamed bupivacaine versus streamed normal saline
Patients will receive 30ml of 0.9% normal saline divided equally and injected prior to port site incisions, then 10ml of 0.5% bupivacaine streamed via port directed at operative field, then 10ml of 0.9% normal saline aerosolized into the coelomic cavity prior to deflation and our current standard of care, which is 30ml of 0.5% bupivacaine, divided equally between the five port-sites, injected at the end of the operation.
Other Names:
  • normal saline
  • bupivacaine
  • marcaine
Experimental: 4
Drug: Aerosolized bupivacaine versus aerosolized saline
Patients will receive 30 ml of 0.9% normal saline divided equally and injected prior to port site incision, then 10ml of 0.9% normal saline streamed via port directed at operative field, then 10ml of 0.5% bupivacaine aerosolized into coelomic cavity prior to deflation and our current standard of care, which is 30ml of 0.5% bupivacaine, divided equally between the five port-sites, injected at the end of the operation.
Other Names:
  • normal saline
  • bupivacaine
  • marcaine
  • aerosolized
Active Comparator: 1
Drug: Injected bupivacaine post-operatively
Patients will receive 30 ml of 0.9% normal saline divided equally and injected prior to port site incision, then 10ml of 0.9% normal saline streamed via port directed at operative field, then 10ml of 0.9% normal saline aerosolized into the coelomic cavity prior to deflation, and our current standard of care, which is 30ml of 0.5% bupivacaine, divided equally between the five port-sites, injected at the end of the operation.
Other Names:
  • bupivacaine
