Tetracaine combined with propofol for painless oocyte retrieval: from a single center study.

BACKGROUND In vitro fertilization-embryo transfer is a main assisted reproductive technique that can improve the success rate of conception. At present, the ultrasound-guided oocyte retrieval is often employed in clinics, but this process will cause pain and fear in outpatients. This study explored the safety and satisfaction of patients who received egg retrieval under vaginal topical tetracaine anesthesia combined with intravenous propofol anesthesia. METHODS Patients who underwent elective egg retrieval in the Reproductive Center of Shanghai Tenth People's Hospital were recruited from January 2017 to August 2018 [tetracaine + propofol group (n=53); propofol group (n=48)]. RESULTS Results showed that tetracaine combined with propofol anesthesia could effectively reduce the dose of propofol during surgery, ensure the quality of follicles, effectively reduce the postoperative pain and improve the operational satisfaction without affecting the prognosis. CONCLUSIONS Our findings provide evidence for further clinical applications of this technique.
