Outcome Measures

Primary Outcomes (1)

  • 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.

    upon arrival to the recovery room after leaving the operating room

Secondary Outcomes (7)

  • Pain Score Assessment-Post-operative Day 1

    Day 1 post surgery

  • Pain Score Assessment-Post-operative Day 3

    Day 3 post surgery

  • Pain Score Assessment-Post-operative Day 7

    Day 7 post surgery

  • Pain Score Assessment Using a Visual Analog Scale-Post-operative Surgical Recheck.

    Approximately day 14 post surgery

  • Measure the Amount of Narcotics Use to Control Pain.

    PACU (from time patient left operating room until patient is discharged from the recovery area to in-patient unit). The time limit for this is generally 60-90 minutes

  • +2 more secondary outcomes

Study Arms (2)

PEC I/II block - pre-operative

ACTIVE COMPARATOR

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 case. The intervention administered to Group I will having the block performed by the anesthesiologist after induction of general anesthesia and prior to surgical incision.

Procedure: PEC I/II blocks by anesthesiologist - pre-operative

PEC I/II block - intra-operative

EXPERIMENTAL

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. Group II will have the block administered by the surgeon after mastectomy is performed and before reconstruction.

Procedure: PEC I/II blocks by surgeon - intra-operative

Interventions

PEC I/II blocks by anesthesiologist - pre-operative; PEC I/II block to anesthetize the pectoral, intercostobrachial, third to sixth intercostal and long thoracic nerves. The PEC 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 (PEC II). Group I will have the PEC block administered by the anesthesiologist prior to surgical incision.

PEC I/II block - pre-operative

PEC I/II blocks by surgeon - intra-operative; PEC I/II block to anesthetize the pectoral, intercostobrachial, third to sixth intercostal and long thoracic nerves. The PEC 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 (PEC II).

Limitations and Caveats

Tools for measuring postoperative pain are subjective. Among the 23 patients who used the electronic reporting format, 58% of the POD 1-14 questionnaires were completed at least one day later, which raises the concern for recall bias. Secondly, our sample size was calculated to detect a difference in mean pain score of 2; however, given the relatively low mean pain scores encountered in our study, this might not be realistic to achieve.
