Analgesic efficacy of ultrasound-guided paravertebral block versus serratus plane block for modified radical mastectomy: A randomised, controlled trial.

Background And Aims: Modified radical mastectomy (MRM) may be associated with severe post-operative pain, leading to chronic pain syndrome. We compared the post-operative analgesic profile of two ultrasound-guided nerve blocks: Paravertebral block (PVB) and serratus plane block (SPB).

Methods: This double-blind, randomised study was conducted on fifty adult females, scheduled for MRM with axillary dissection.
