Official title:
Enhanced Pain Control After Reduction Mammaplasty With Bupivicaine and Dexamethasone Regional Block: a Double-blind Randomized Controlled Trial
The addition of dexamethasone to non-liposomal bupivacaine in perineural blocks has been shown to enhance pain control and prolong the time until first request for postoperative narcotics in the fields of orthopedic, thoracic, and gynecologic surgery. This has not been investigated in any types of breast surgery. The investigators assessed if the combination of dexamethasone to bupivacaine in the preoperative field block prior to bilateral breast reduction surgery resulted in improved pain control relative to bupivacaine alone.
The investigators conducted a double-blind randomized controlled trial to determine whether the addition of dexamethasone to bupivacaine in a preoperative Pecs II block resulted in improved pain control, relative to bupivacaine alone, in patients undergoing bilateral reduction mammaplasty. Using a preassigned randomization list, patients were randomized to experimental and control groups in a ratio of 1:1 upon enrollment. Both groups received PECS II bupivacaine field blocks in the preoperative holding area, performed by an acute pain fellowship-trained anesthesiologist. The experimental group received 29mL of 0.5% bupivacaine mixed with 1mL 4mg/mL dexamethasone per side. The control group received 29mL 0.5% bupivacaine mixed with 1mL 0.9 saline solution per side. To maintain the blinded aspect of the study, the anesthesiologists were given pre-mixed vials labelled uniformly for the trial, regardless of the patient's treatment arm. The patients all underwent bilateral breast reduction with a single surgeon. Postoperative pain regimens were standardized. Subjective pain scores, narcotic consumption, 4-hour interval vital signs, anti-emetic usage, and postoperative quality of life via an sf-36 questionnaire were all recorded per patient. ;
