About

The optimal analgesia method in video-assisted thoracoscopic surgery (VATS) remains controversial. 105 patients scheduled to undergo video-assisted thoracic surgery under general anesthesia will be included. Patients will be randomly allocated to receive ultrasound-guided ESP blocks on T4 and T6 levels (Group ESPB, n = 35),PVB (Group PVB, n = 35) after the anesthesia induction and turning the patient in the lateral position or (Group ICNB, n=35) with 30 mL 0.5% bupivacaine +50 µ adrenaline will be injected by the surgeon through the thoracoscope .

Full description

Standard general anesthesia was applied Patients will be randomly allocated to receive single shot of ESP blocks (Group ESPB), Paravertebral blocks (Group PVB) or (Group ICNB )at T4 and T6 levels according to a random number list that will be generated by a computer and will be stored in sealed envelopes. An independent experienced anesthesiologist will perform the first two blocks or surgeon will perform the third one through the thoracoscope according to the random number. The study coordinator, attending anesthesiologist, data collection resident and the patients will be all blinded to the treatment group assignment. All blocks will be applied on patient's back in a lateral position. Postoperative analgesia regimen consisted of a continuous infusion of iv iboprofen and morphine as a second rescue drug. Demographic data, past medical history, surgical and anesthetic data will be documented. Postoperative pain scores, consumption of analgesia and quality of recovery will be recorded to evaluate the analgesic effect.
