COMPARISON OF ULTRASOUND GUIDED RECTUS SHEATH BLOCK AND OBLIQUE SUBCOSTAL TRANSVERSUS ABDOMINIS PLANE BLOCK FOR PERIOPERATIVE ANALGESIA FOR MIDLINE INCISION ABDOMINAL SURGERIES

ABSTRACT: Intervention1: Rectus sheath block: A USG machine with linear array probe (5-12MHz) with an imaging depth of 4-6cm will be used for performing the block. The ultrasound probe will be placed transverse on abdomen, immediately lateral (3 cm) to umbilicus. A 20-gauge needle will be inserted in-plane in a medial to lateral orientation, through the subcutaneous tissue, to pierce through the anterior rectus sheath. Upon identification of the rectus muscle and hyperechoic twin lines deep to it (posterior rectus sheath and fascia transversalis) in the ultrasound image the needle tip will be advanced to the desired position, posterior to the rectus muscle and above the underlying posterior rectus sheath under direct vision. Following con�rmation of the correct position of the needle tip with hydro dissection of the rectus muscle away from the posterior rectus by administration of 0.51ml of normal saline; 20ml of 0.25% bupivacaine will be administered for block performance. The procedure will be repeated on the opposite side. Intervention2: oblique subcostal Transversus abdominis plane block: A USG linear array probe with high- or an intermediate-frequency linear probe of 35 to 40 mm will provide adequate imaging. A needle of up to 15 to 20 cm in length , bend into a slight curve will be required , decribed by Hebbard et al .15 The operator will stand on the left side of the patient in the supine position, and both sides are blocked from this position, with the right hand holding the needle and the left hand holding the probe. To perform the block, the rectus abdominis and underlying transversus abdominis muscles will be identified near the costal margin and xyphoid. Local anesthetic is injected incrementally in the TAP (hydrodissection) by a needle passing along the obliq Primary outcome(s): �To assess the analgesic efficacy of rectus sheath block. �To assess the analgesic efficacy of oblique subcostal TAP block. �To compare the analgesic efficacy of both blocks.
