Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose if to find out if analgesia with bilateral ultrasound-guided Tranversus Abdominis Plane (TAP) block with Ropivacaine 0.5% is better than analgesia with local infiltration of trochar sites with Ropivacaine 0.5% in patients undergoing laparoscopic cholecystectomy.

Our hypothesis is that in laparoscopic cholecystectomy, bilateral TAP blocks will reduce postoperative pain scores when compared to conventional postoperative pain control with local infiltration of trochar insertion sites.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Patient ages 18-64
2. American Society of Anesthesiology Physical Status I, II or III
3. Inpatients scheduled to undergo laparoscopic cholecystectomy at Ben Taub General Hospital

Exclusion Criteria

1. Open cholecystectomy - excluded due to increased levels of pain in open procedures
2. Scheduled for ambulatory surgery
3. Renal dysfunction (Serum Cr \> 1.2) - excluded due to potential altered metabolism of anesthetic and pain medications
4. Coagulopathy or anticoagulation - increased risk of bleeding from nerve block injection
5. Allergy or contraindication to any of the study medications or anesthetic agents
6. Chronic opioid analgesic use at home - excluded due to potential difficulty in assessing pain caused by the procedure alone
7. Patient inability to properly describe postoperative pain to investigators (language barrier, dementia, delirium, psychiatric disorder)
8. Pregnancy
9. Prisoners
10. Patient or surgeon refusal
