Participants in this arm will receive intravenously (IV) matching equal dose of placebo while recovering in the post anesthesia care unit (PACU) on the day of the surgery after subject has been deemed to be stable (hemodynamically stable, awake). The study physician will administer the study intervention via an intravenous pump to deliver equal volume saline over at least 30 minutes.

GAD-7 consists of 7 problems. Participants report how often they have been bothered by the 7 problems over the last 2 weeks on a Likert Scale from 0 (not at all) to 3 (nearly every day). The total score range is 0-21; the higher the score, the more severe the anxiety. 0-4=minimal anxiety, 5-9=mild, 10-14=moderate, 15-21=severe anxiety.

A Health-Related Quality of Life (HRQoL) patient self-report tool used to measure the wide range of effects that endometriosis can have on patients' lives, including work, relationship with child/children, sexual relationship, feelings about medical profession, feelings about treatment, and feelings about infertility. The EHP-30 questions are asked regarding endometriosis in the previous 4 weeks and are answered on a 5-point Likert scale, where 0=never, 1=rarely, 2=sometimes, 3=often, and 4=always. Raw scores for the questions within a scale are summed and transformed to a 0-100 scale, with higher scores indicating worse HRQoL.

Opioid use will be assessed through medical records and subject reports. Assessment of opiate use will be used to determine the opiate-sparing effects of the study drug.

Placebo: Participants in this arm will receive intravenously (IV) matching equal dose of placebo while recovering in the post anesthesia care unit (PACU) on the day of the surgery after subject has been deemed to be stable (hemodynamically stable, awake). The study physician will administer the study intervention via an intravenous pump to deliver equal volume saline over at least 30 minutes.

VAS is a tool widely used to measure pain. A patient is asked to indicate his/her perceived pain intensity (most commonly) along a 100 mm horizontal line, and this rating is then measured from the left edge (=VAS score). The total score range is 0 (no pain) to 10 (worst pain imaginable); the higher the score, the worse the pain.

Only 1 participant was enrolled, participant was lost to follow up before any outcome measure data was collected.
