Brief summary
The primary objective of this study is to assess differences in postoperative pain experienced by pediatric patients having transversus abdominis plane block block with bupivacaine (0.125% and 0.25%) compared with control group will receive conventional iv analgesia after Laparoscopic surgery.
Detailed description
A prospective randomized controlled double blind study using a computer generated randomization will be conducted in Assiut University Hospitals and carried on 60 pediatric patients undergoing laparoscopic surgery under general anesthesia. After induction of general anesthesia and endotracheal intubation, patients in group B and group C will be placed in the supine position and transversus abdominis plane block will be performed under ultrasound guidance. After skin preparation, the linear ultrasound probe connected to a portable ultrasound unit will be placed in the axial plane across the mid-axillary line midway between the costal margin and the highest point of iliac crest. needle attached to a syringe filled with the Local anesthetic solution will be inserted until it reaches the plane between the internal oblique and transversus abdominis muscles. After careful aspiration to exclude vascular puncture, injection of bupivacaine will be performed leading to separation between the internal oblique and the transversus abdominis muscles which will appear as a hypoechoic space on ultrasound. This procedure will be repeated on the opposite side . Laparoscopic procedure will be started 20 minutes after completion of bilateral transversus abdominis plane block and 0.01 mg/kg iv atropine will be given before pneumoperitonem. Intra abdominal pressure will be maintained at 10-12 mmHg. The use of opioids during the procedure will based on the cardiovascular response to stimulation; a heart rate increase of 20% from baseline will be interpreted as insufficient analgesia and will be treated with fentanyl in doses of 1mcg / kg.
Interventions
Patients will receive bilateral Transversus Abdominis Plane Block guided by ultrasound device using bupivacaine (Marcaine, 0.125%), 0.5 ml/kg on each side.
DRUGBupivacaine 0.25%
Patients will receive bilateral Transversus Abdominis Plane Block guided by ultrasound device using bupivacaine (Marcaine, 0.25%), 0.5 ml/kg on each side.
