Comparison Between Dexmedetomidine and Fentanyl As an Adjuvant to Bupivacaine in the Paravertebral Nerve Block in Laparoscopic Cholecystectomy for Postoperative Analgesia: Randomized Comparative Clinical Trial.

Sponsor: Assiut University

Summary

Laparoscopic cholecystectomy is one of the most common surgeries today, cause it has many advantages over open cholecystectomy. Although these advantages pain remains a big problem after laparoscopic cholecystectomy which causes patient admission or readmission. This post-operative laparoscopic cholecystectomy pain causes extreme patient discomfort, extended post-anesthesia care unit stay and restricts early recovery. To overcome this problem, there were trials of inta abdominal instillation with local anesthetics with no positive results , so they combined this with local infiltration at the laparoscopic access sites with no satisfactory postoperative analgesia. The aim of this study is to evaluate the effect and the difference between dexmedetomidine and fentanyl in pre-operative unilateral (T5\&6) thoracic paravertebral block for postoperative analgesia in laparoscopic cholecystectomy
