Comparison of Quality of Recovery following Ultrasound-guided Erector Spinae Plane Block with Levobupivacaine Alone or Combined with Dexmedetomidine or Magnesium Sulfate in Modified Radical Mastectomy: A Randomised Controlled Study

Background and Aims: Optimising post-operative quality of recovery (QoR) is a key goal of perioperative care, particularly in breast cancer surgery, where pain, emotional distress and opioid-related issues can adversely influence the outcome. This study aimed to compare the QoR in terms of physical independence, psychosocial aspects, pain and emotional status assessed using the QoR-15 questionnaire, following erector spinae plane (ESP) block with levobupivacaine alone or with adjuvants in patients undergoing modified radical mastectomy (MRM).
