Brief Summary

Pain following mastectomy surgery for breast cancer can be significant. Poorly managed pain in the immediate time-period following surgery can potentially lead to long-term (chronic) pain conditions. There is still a need to find the safest, least invasive, and most effective method to manage this pain. The investigators believe that a new technique of injecting local anesthesia (freezing) in to specific areas at the end of mastectomy surgery may be a very important step to managing pain after breast surgery. The investigators would like to begin by performing a pilot study, meaning the investigators will perform the technique in patients and compare what their pain outcomes are to patients who have not had the technique.

Outcome Measures

Primary Outcomes (1)

  • Change in subjective Visual Analogue Scale (VAS)

    The visual analogue scale is administered at different time points

    7 days after surgery

Secondary Outcomes (1)

  • Patient Adverse Event Outcomes

    72 hours post operatively

Study Arms (2)

Local Anesthetic Injection

EXPERIMENTAL

The intervention involves injection of local anesthetic (0.25% bupivacaine with 1:200,000 epinephrine) under direct vision in the serratus anterior muscle plane at the end of surgery. Local Anesthetic Injection above the serratus anterior

Drug: Local Anesthetic Injection above the serratus anterior

Control Arm

NO INTERVENTION

Retrospective control group who have not had the new injection technique.

Interventions

This is a quantitative pilot study assessing whether a new technique of local anesthesia injection during mastectomy surgery gives better pain outcomes than the standard methods. Patients who meet inclusion criteria will be invited to partake and all patients will have the injection technique. These patients will then be monitored for pain outcomes up to 7 days following the surgery and the results compared with historical results from patients who have already had the surgery.

Also known as: Injection to serratus anterior muscle at the end of surgery
Local Anesthetic Injection
