Comparative evaluation of bupivacaine with magnesium sulphate and dexamethasone as adjuvants in ultrasound-guided transversus abdominis plane block for open unilateral inguinal hernia surgeries: A randomised controlled trial.

Background And Aims: Inguinal hernia repair is associated with moderate to severe pain that is most extreme in the first 24 hours. The aim of this study was to compare the efficacy of dexamethasone versus magnesium sulphate (MgSO) with bupivacaine in ultrasound-guided transversus abdominis plane (TAP) block for patients undergoing unilateral inguinal hernioplasty.

Methods: Eighty patients were randomly allocated to two groups to receive ultrasound-guided TAP block postoperatively with either 20 ml of 0.
