A comparison of nerve stimulator guided paravertebral block and ilio‐inguinal nerve block for analgesia after inguinal herniorrhaphy in children

Summary The aim of this study was to compare the efficacy of nerve stimulator guided paravertebral block with ilio‐inguinal nerve block in children undergoing inguinal herniorrhaphy. Eighty children were randomly allocated to receive either paravertebral block or ilio‐inguinal nerve block. Each block was evaluated in terms of intra‐operative haemodynamic stability, postoperative pain scores at rest, on movement and during activity, requirement for supplemental analgesia and parental satisfaction. Haemodynamic stability was maintained significantly better during sac traction in the paravertebral block group (p
