Assessing Ketorolac (Toradol) at Oocyte Retrieval

Phase 1

Recruiting

• Conditions: Infertility; Infertility, Female; Embryo Transfer; Postoperative Pain; Oocyte Retrieval
• Interventions: Drug: Ketorolac (Toradol); Other: Placebo (saline)

• Registration Number: NCT06026553
• Lead Sponsor: Shady Grove Fertility Reproductive Science Center

Brief Summary

To determine if a nonsteroidal anti-inflammatory drug (NSAID), Ketorolac (Toradol), can improve pain control and decrease narcotic use after undergoing egg retrieval.

Detailed Description

Postoperative pain control is an essential component to any surgical procedure. Surgery represents a time during which opioid-naïve patients may be exposed to narcotics, risking opioid related complications and future opioid-use disorder. Approximately 150,000 oocyte retrievals are performed per year in the United States, according to the 2017 Assisted Reproductive Technology National Summary Report. A reduction in exposure to narcotics in this field has significant public health implications, particularly given that approximately 6% of new persistent opioid use occurs following minor surgical procedures.

Ketorolac (Toradol) has been demonstrated to be a safe and efficacious agent to achieve pain control postoperatively with no significant increase in adverse events.

The purpose of this prospective randomized blinded placebo controlled trial is to determine if a nonsteroidal anti-inflammatory drug (NSAID), Ketorolac (Toradol), can improve pain control and decrease narcotic use after undergoing egg retrieval.

Approximately 400 women (n=200 in each arm) will be enrolled according to the inclusion/exclusion criteria among patients of Shady Grove Fertility. Participants will undergo a standard in vitro fertilization cycle (IVF) followed by egg retrieval (ER). Participants will be randomized to receive either IV ketorolac or IV placebo at the conclusion of the egg retrieval, administered by the anesthesia provider. All enrolled patients will receive standard post-operative pain management. The investigational component of this study lies in assessing post-operative pain control in the immediate post-operative period and in the post-operative period after discharge as reflected by pain scores and narcotic medication usage.

Arm && Interventions

Group	Intervention	Description
Standard post-operative pain management + Ketorolac (Toradol)	Ketorolac (Toradol)	Subject will undergo an IVF cycle with ovarian hyperstimulation and oocyte retrieval. Standard protocols will be used for both study groups and involve administration of gonadotropins to stimulate ovarian follicle growth and regular monitoring with ultrasound and serum estradiol and progesterone levels until follicles reach a desired size. Human Chorionic Gonadotropin (HCG) or leuprolide acetate will be administered to trigger final oocyte maturation prior to oocyte retrieval under anesthesia. On the day of oocyte retrieval, the anesthesia provider will provide syringes of IV ketorolac (30 mg if ≥50 kg or 15 mg if \<50 kg per manufacturer dosing) or IV placebo (saline). If assigned to the study arm, IV ketorolac will be administered by the anesthesia provider. All enrolled patients will receive standard post-operative pain management. Patients will be contacted post-operatively, to access pain scores and record the amount of the prescribed narcotic medications utilized since discharge.

Primary Outcome Measures

Name	Time	Method
Administration of IV narcotic for rescue analgesia during recovery in the post anesthesia care unit (PACU)	Oocyte retrieval procedure day	The primary objective is to evaluate the use of ketorolac as a safe and effective analgesic after transvaginal oocyte retrieval (TVOR) by assessing the number of patients requiring additional analgesia with IV narcotic during recovery in the post anesthesia care unit (PACU).

Secondary Outcome Measures

Name	Time	Method
Dose of narcotic for rescue analgesia during recovery in the PACU	Oocyte retrieval procedure day	Dose of narcotic administered for rescue analgesia during recovery in the PACU
Incidence of complications and adverse events	From oocyte retrieval procedure day up to 1 week post oocyte retrieval	Data will be collected on the oocyte retrieval procedure including complications and adverse events in the intra-operative and post-operative periods
Intensity of pain in PACU	Oocyte retrieval procedure day	Pain (measured on a scale of 0 (no pain) to 10 (worst pain imaginable)): PACU pain scores (scored 0-10)

Type of narcotic for rescue analgesia during recovery in the PACU	Oocyte retrieval procedure day	Type of narcotic administered for rescue analgesia during recovery in the PACU
Intensity of pain at baseline	Oocyte retrieval procedure day	Pain (measured on a scale of 0 (no pain) to 10 (worst pain imaginable)): baseline pain score
