Overview
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
Detailed description
The para-vertebral block has been largely used over the past years for post-operative analgesia. Many reports in the literature describe the use of thoracic paravertebral block for providing post-laparoscopic cholecystectomy analgesia. Thanks to the ultrasound, over the past years, paravertebral blocks (PVB) have been increasingly used for providing postoperative analgesia, and in the administration of thoracic paravertebral block which has greatly reduced the incidence of associated complications.
Contrary to the intra-abdominal instillation of local anesthetics and local infiltration, the paravertebral blockade has been reported to provide high-quality afferent blockade with the abolishment of somatosensory evoked potentials. and has also been found capable of attenuating the postoperative stress response associated with traditional cholecystectomy.
Interventions
- Drug Bupivacaine and Dexmedetomidine
Adult patients will take 10 ml Bupivacaine 0.5% plus 2ml solution of Dexmedetomidine 1mic/kg in the bilateral T5\&6 preoperatively - Drug Bupivacaine and Fentanyl
Adult patients will take 10 ml Bupivacaine 0.5% plus 2ml solution of Fentanyl 20 microgram with the bilateral T5\&6 preoperatively
