Ultrasound Guided Erector Spinae Plane Block Reduces Postoperative Pain Following Laparoscopic Colorectal Operation: A Randomized Controlled Study

The goal of this study is to evaluate the effect of ultrasound guided erector spinae plane block on postoperative pain and quality of recovery after laparoscopic colon surgery.

After induction parturient in the ESPB underwent bilateral ESPB at the level of T7 using a linear ultrasound (US) transducer. Intravenous fentanyl patient control device 24-hour fentanyl consumption will be recorded.

No regional anesthesia technique will be applied to the control group. Intravenous fentanyl patient control device 24-hour fentanyl consumption will be recorded.

The transducer was placed vertically 3cm lateral to the midline to visualize the muscles of the back, transverse process and the pleura in between the two transverse processes. After local infiltration of the needle insertion site with 2-3 ml of 2% lidocaine needle was inserted in cranial-caudal direction towards the transvers process using in plane technique until the needle cross all the muscles then interfascial injection of 20ml local anesthetics is done after ensuring negative aspiration, the procedure was repeated following the same steps on the other side of the back.

Inclusion Criteria: aged between 20 and 70 years, with an American Society of Anesthesiologists physical status of 1 or 2, who were scheduled for laparoscopic colorectal operation Exclusion Criteria: sensitivity to local anesthetic, bleeding disorders , receiving anticoagulant, body mass index (BMI) over 35/kg/m2 spine or chest wall deformity pregnancy tolerance to opioid analgesics inability to use patient-controlled analgesia (PCA)
