Triamcinolone Versus Methylprednisolone in Transversus Abdominis Plane Block

Overview

In the current Study we will compare between triamcinolone and methylprednisolone as an additive to bupivacaine drug in ultrasound guided TAP block in major open abdominal surgery .

Postoperative pain is one of the main causes of respiratory function derangement after abdominal surgery .Transversus abdominis plane (TAP) block is widely used in abdominal surgery for postoperative analgesia The transversus abdominis plane (TAP) block is aperipheral nerve block that involves the injection of alocal anesthetic (LA) in the plane between the internaloblique and transversus abdominis muscle layers, with the aim of anesthetizing the intercostal nerves supplyingthe abdominal wall (from T6 to L1) By blocking intercostal nerves T6 to L1, TAPblock efficiently blocks somatic pain after abdominalwall surgery . It providesadequate postoperative pain relief following various abdominal surgeries TAP block can reduce pain scores, opioid consumption, and the incidence of opioid-related complications after abdominal surgery. The duration of the TAP block is limited to theeffect of the administered LAs. Various adjuvantmedications have been added to the LA to prolong theduration of TAP block and magnify its effects . Perineural injection of steroids is reported to influence postoperative analgesia. As a synthetic glucocorticoid, triamcinolone acetonide binds to and activates the glucocorticoid receptor to produce anti-inflammatory responses,such as down-regulating pro-inflammatory cytokine expression , preventing prostaglandin and leukotriene synthesis and release of arachidonic acid, and activating anti-inflammatory transcription factors such as lipocortins
