Brief summary

Laparoscopic cholecystectomy is a widely employed procedure in ambulatory surgery. Pain after laparoscopic cholecystectomy arises significantly from port site incisions in the anterior abdominal wall. Innervation of the anterior abdominal wall is segmentally supplied by pain afferents in the plane of fascia between transversus abdominis and the internal oblique muscles. Opioids analgesia is used to control postoperative pain, but it carries the risk of increased nausea and vomiting, ileus and sedation that may delay hospital discharge. Several techniques have been tried as.neuroaxial narcotics, intraperitoneal lavage of local anesthetic and transversus abdominis plan (TAP) block and successfully reduced opioid use and improve postoperative analgesia. The ultrasound-guided erector spinae plan(ESP) block is a recently described technique which produces reliable unilateral analgesia at thoraco-lumbar dermatomes. ESP block carries the advantages of being simple, safe, easily recognizable by ultrasound, and a catheter can be threaded to extend the duration of analgesia. Few case series reported the efficacy of (US)-guided ESP blocks in reducing postoperative pain and opioids consumption. Because of that, the investigators aimed to test the hypothesis that US-guided ESP blocks can decrease opioid consumption during the first 24 h after of laparoscopic cholecystectomy in comparison with the conventional systemic analgesia.

Interventions

PROCEDUREErector Spinae Plan Block

The trocar site incision was done 15 minutes after the block in the three groups. The skin was disinfected with chlorhexidine solution, and the high-frequency transducer was isolated with a sterile disposable plastic cover and gel. The patient was placed in lateral position. A high-frequency linear ultrasound probe was placed longitudinally lateral to the T8 spinous process by 3 cm. After identification of the 3 muscles superficial to the hyperechoic transverse process shadow as follows: trapezius, rhomboid major, and erector spinae. The needle was introduced in a cephalo-caudal orientation. The needle tip was positioned fascial plane between rhomboid major and erector spinae muscles. Hydrodissection by 1-2 ml of normal saline to visualize the plan, then deposition of local anesthetic was done. A total of 20 mL of 0.25% bupivacaine was injected here. The same procedure was repeated on the other side.
