This is a prospective observational study. Investigators want to understand post-operative recovery for patients undergoing mastectomy at NorthShore University HealthSystem. Some of these patients receive PECS blocks with Liposomal Bupivacaine and some do not receive a block. Investigators want to know whether patients who receive a block have better post operative recovery and pain control than patients who do not receive one. Investigators also want to understand whether PECS blocks with Liposomal Bupivacaine improves quality of recovery at 72 hours post operatively.
Investigators plan to approach and consent 800 patients undergoing mastectomy, 400 with PECS blocks and 400 without. Investigators will assess their quality of recovery using the QoR 15 survey at 72 hours post operatively. In addition, investigators will also record VAS scores immediately postoperatively and at 24, 48, and 72 hours postoperatively. The study team will also calculate the total morphine equivalents (MMEs) required for each patient after 72 hours.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| PECS Block with Liposomal Bupivacaine | The patients in this cohort will undergo a PECS block with Liposomal Bupivacaine before their mastectomy. Patients will receive Liposomal Bupivacaine in combination with 0.25% Bupivacaine in a 1:1 mixture for the purpose of post-operative pain control. |
| |
| No PECS block | The patients in cohort will not undergo a PECS block. Pain will be controlled in the usual fashion with IV and oral medications. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Mastectomy with PECS blocks | Procedure | Approximately half of patients recruited will receive a PECS block with Liposomal bupivacaine and half will not receive a block. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Quality of Recovery 15 Survey | Patients will complete the quality of recovery 15 survey 72 hours after surgery. This is a scale from 0 to 150. A score of 150 indicates better post operative recovery. | 72 hours post operatively |
| Measure | Description | Time Frame |
|---|---|---|
| Visual analog scale | This is a pain scale from zero to ten. A score of 10 indicates worse pain. | Immediately post operatively |
| Visual analog scale | This is a pain scale from zero to ten. A score of 10 indicates worse pain. |

| Liposomal bupivacaine | Drug | All of the PECS blocks performed at this institution have liposomal lupivacaine as the anesthetic. Investigators will examine quality of recovery and pain control in patients who receive a PECS block versus those who do not receive one. |
