Clinical Trial Summary

The investigators will compare whether patients will have better pain control if they were to receive (PEC I/II block) before surgery or after mastectomy.

Description:

The current standard of care at the University of Iowa is to receive a pectoralis nerve block (PEC I/II) prior to surgery for mastectomy and reconstruction cases. The investigators will compare whether patients will have better pain control if they were to receive (PEC I/II block) before surgery or after the mastectomy. Patients undergoing mastectomies at the University of Iowa Hospitals clinics receive general anesthesia and a regional block for pain control. The most commonly employed regional anesthetic technique is a PECS I/II block to anesthetize the pectoral, intercostobrachial, third to sixth intercostal and long thoracic nerves. The PECS I/II blocks are pectoralis field blocks where local anesthetic medication is injected under ultrasound guidance between the tissue planes of pectoralis major and minor muscles (PECS I) and in the plane of the serratus anterior muscle at the level of the third rib (PECS II). The investigators will randomize patients into two groups and blind the patient and the research assistant collecting the data. Group I will have the block performed after induction of general anesthesia and prior to surgical incision by the anesthesiologist. Group II will have the block administered by the surgeon after mastectomy is performed and before reconstruction. On the day of surgery, the investigators will have patients fill out forms to measure pain catastrophizing and depression and anxiety. The investigators would like to measure if there is any difference in postoperative pain scores (visual analogue scale)-immediately post surgery in post-anesthesia care unit (PACU), and then on the admission unit every 4 hours for the first twenty four hours or on discharge (whichever time-point occurs sooner) and will collect the average pain scale of the day on post-op day (POD) 2,3,5 and 7 via patient communication electronic message in RedCap. The investigators will also measure intraoperative and post-operative narcotic use (converted to morphine equivalents), post-operative nausea and vomiting, length of (PACU) stay. In addition the investigators will also collect pain scores and pain catastrophic scale on POD 14 after surgery at their clinic visits to the surgeon. Other data collected will include time taken to perform block, post-operative infection rate and post-operative flap necrosis rate.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain score assessment using a visual analog scale-Immediately post-surgery	The primary outcome to be assessed is to determine if there is a quantitative difference in post-operative pain scores as a result of the administration of a pre-operative PECS I/II block versus the administration of an intra-operative PECS I/II block (Post mastectomy but prior to breast reconstruction). The visual analog scale is a unidimensional measure of pain used in a diverse adult population. The numeric values are on a continuous scale from 0 to 10 with 0 indicating no pain, 5 being moderate pain and 10 as intense pain.	The initial assessment will occur immediately post-surgery.
Secondary	Pain score assessment-Post-operative day 2	Using electronic patient communications, the investigators will ask patients to report their average pain using a numeric values. The numeric values are on a continuous scale from 0 to 10 with 0 indicating no pain, 5 being moderate pain and 10 as intense pain.	Day 2 post surgery
Secondary	Pain score assessment-Post-operative day 3	Using electronic patient communications, the investigators will ask patients to report their average pain using a numeric values. The numeric values are on a continuous scale from 0 to 10 with 0 indicating no pain, 5 being moderate pain and 10 as intense pain.	Day 3 post surgery
Secondary	Pain score assessment-Post-operative day 5	Using electronic patient communications, the investigators will ask patients to report their average pain using a numeric values. The numeric values are on a continuous scale from 0 to 10 with 0 indicating no pain, 5 being moderate pain and 10 as intense pain.	Day 5 post surgery
Secondary	Pain score assessment-Post-operative day 7	Using electronic patient communications, the investigators will ask patients to report their average pain using a numeric values. The numeric values are on a continuous scale from 0 to 10 with 0 indicating no pain, 5 being moderate pain and 10 as intense pain.	Day 7 post surgery
Secondary	Pain score assessment using a visual analog scale-Post-operative surgical recheck.	When the patient returns to visit with their surgeon approximately 14 days after their surgical procedure, using the visual analog scale the subjects will report their average pain score. The numeric values are on a continuous scale from 0 to 10 with 0 indicating no pain, 5 being moderate pain and 10 as intense pain.	Approximately day 14 post surgery
Secondary	Measure the amount of narcotics use to control pain.	The investigators will report the amount of narcotics required (converted to morphine units) to provide pain relief to subjects.	For up to two weeks following surgery
