ESPBs vs TAPs for Satisfactory Analgesia Following DIEP Surgery

Not Applicable

Recruiting

• Conditions: Pain

• Registration Number: NCT06091241
• Lead Sponsor: University of Kansas Medical Center

Brief Summary

Breast cancer is the second most common cancer diagnosed in American women . For patients who have undergone surgical mastectomy, autologous breast reconstruction is an alternative option to breast implants. Deep Inferior Epigastric Perforator (DIEP) flaps are the gold standard for autologous breast reconstruction . Effective pain control following surgery is imperative and ultrasound-guided bilateral transversus abdominis plane blocks (TAPs) with the infiltration of local anesthetics, such a bupivacaine are a common regional technique of choice . A newer described technique, bilateral Erector Spinae Plane blocks (ESPBs) (which also are an infiltration of local anesthetic) present as an alternative approach for post-operative analgesia. ESPBs have been proven efficacious in reducing intra- and post-operative opioid requirements, lessening the need for rescue analgesics in other similar surgical procedures.

The hypothesis is that preoperative bilateral ESPBs could provide equivalent pain control as a regional analgesic for patients undergoing DIEP flap surgery when compared to preoperative bilateral TAPs

Secondary Outcome Measures

Name	Time	Method
Numerical Rating Scale	6 months post-operation	Scale used to measure pain on scale from 0-10 (0 is 'no pain' and 10 is 'the worst pain imaginable')
Mean Morphine Equivalents	48 hours post injection	Amount of opioid pain medications administered and converted to morphine equivalents
Michigan Body Map	24 hours post injection	Map used to show body location of worst site of primary pain
