Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Prospective, randomized study.Forty patients with American Society of Anaesthesiologists (ASA) I-II physical status, aged 3-15 years.Patients are randomly allocated into two groups and are administered general anesthesia and before the beginning of surgery ultrasound guided RSB with 0.2 ml.kg-1, 0.25% of levobupivacaine and thirty minutes before the surgery the loading dose of morphine of 0.1 mg.kg-1 intravenously are received in group RSB and group M, respectively. Patient controlled analgesia (PCA) device with 0.01 mg.kg-1 bolus dose of morphine and 30 minutes lockout interval is set up postoperatively in both groups.
