Study Description

Brief Summary:

The central objective of this study will be to evaluate the relationship between estrogen levels and the pain following oocyte retrieval in women undergoing in vitro fertilization.

Condition or disease	Intervention/treatment	Phase
Oocyte Retrieval Postoperative Pain	Drug: Fentanyl Drug: Acetaminophen Drug: Oxycodone	Phase 4

Detailed Description:

Subject will undergo standard clinical protocols for the entire oocyte stimulation cycle and all assisted reproductive procedure decisions and algorithms will be decided entirely independent of this study.

The anesthetic and postoperative pain regimens will use the same agents and dose ranges used in clinical standard practice; however, the regimens will be standardized, so as to limit confounding variables. The study regimen for anesthesia will differ from the current, clinical standard by the mandated use of actual body weight (in current practice, actual, adjusted ideal, or ideal body weights are used), the use of fentanyl 1 mcg/kg IV (instead of 100 mcg for everyone), and the standardization of postoperative analgesia (noted below). The total amount of fentanyl, propofol, and postoperative drugs will be recorded.

Postoperative analgesia will be standardized based on the subject's self reported verbal analogue score (VAS) and the timing of the report. The agents and timing used below differ from the current clinical standard by assessing VAS and responding with a certain regimen.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Analgesia options Protocolized analgesia based on VAS degree of discomfort and time. Analgesic options include heating pad, acetaminophen, percocet (oxycodone), fentanyl 0.5-1 mcg/kg.

Outcome Measures

Primary Outcome Measures :

Amount of Discomfort [ Time Frame: PACU admission, 15, 30 and 60 min postprocedure, postoperative day 3 ]
Change in discomfort following oocyte retrieval with standardized anesthesia management as measured by verbal analogue scoring (0-10 scale). VAS scores correlate to minimal (VAS 0-3), moderate (VAS 4-6) or severe (VAS ≥7) discomfort.

Secondary Outcome Measures :

Amount of Discomfort Following Discharge Until Embryo Transfer [ Time Frame: After 1 hrs but less than 3 days ]
Change in discomfort following oocyte retrieval with standardized anesthesia management as measured by verbal analogue scoring (0-10 scale) after immediate postoperative period (1 hrs) but prior to Embryo Transfer on 3rd postoperative day. Visual Analogue Scale (VAS) scores correlate to minimal (VAS 0-3), moderate (VAS 4-6) or severe (VAS ≥7) discomfort. Patients will record the type, dose, and timing of pain medicines in a diary to be returned at Embryo Transfer.
