Randomized Controlled Trial Comparative Study Clinical Trial
Preemptive bupivacaine offers no advantages to postoperative wound infiltration in analgesia for outpatient breast biopsy.
Adequate analgesia is important after surgery and in particular after ambulatory surgery. Preemptive administration of analgesics, ie, prior to commencing surgery, has many theoretical advantages. ⋯ The administration of local anaesthesia prior to starting surgery does not appear to have any advantage over its postoperative administration in patients undergoing ambulatory breast biopsy.
