The goal of this clinical trail is to determine if bilateral erector spinae plane block alone can provide good perioperative analgesia for abdominoplastic surgery patients or it is better to give combined bilateral rectus sheath and erector spinae plane blocks to achieve effective intraoperative and postoperative analgesia with minimal morphine consumption in such operations in which there is an extensive surgical dissection and a high risk of respiratory problems.

This study is randomized controlled trail in which 40 adult patients (male or female) scheduled for elective abdominoplastic surgeries during the study duration will be randomized into to equal groups to investigate the efficacy of erector spinae plane block alone versus the efficacy of combine use of erector spinae and rectus sheath plane block for intra and postoperative analgesia in abdominoplastic surgery patients.

Inclusion Criteria:

• patients Age from 21 to 60 years ,Male and female patients ,ASA I, II patients scheduled for elective abdominoplastic surgeries during the study duration.

Exclusion Criteria:

• Patient refusal, Age less than 21 and above 60 years old, ASA III, IV patients., Infection at the site of injection, Opioid addiction, Allergy to any used substances (lidocaine, bupivacaine)., Preexisting severe or uncontrolled respiratory, renal or cardiac disease. , INR more than 1.5 and platelets less than 100000.
