Successful prevention of follicular rupture at 45 h after hCG and GnRHa triggering by emergent administration of indomethacin: A case report.

Objective: To report the management and prevention of pre-operative ovulation before oocyte retrieval with emergent administration of indomethacin. Case report: During in vitro fertilization (IVF) treatment, the patient described here mistakenly administered 6500 IU of hCG and 0.2 mg of triptorelin (GnRHa) 9 h earlier than scheduled triggering. To avoid emergent oocyte retrieval in the midnight, indomethacin was given (150 mg/day, there times a day) from 2 h after incorrect hCG and GnRHa injection to the night before ovum pickup. The oocyte retrieval was performed at originally scheduled time. The result showed that pre-operative ovulation was effectively prevented and we successfully collected the expected number Andersen et al., 1995 of oocytes at 45 h after triggering. Conclusion: The presented case demonstrates that indomethacin can be used safely and effectively as an emergent prescription to prevent and postpone ovulation till up to 45 h after hCG and GnRHa triggering.
