Influence of Different Suction Pressure Values During Oocyte Retrieval on Pregnancy Outcome
Objective:To explore the influence of different suction pressure values on pregnancy outcome during egg retrieval.Methods:107 infertility patients with assisted reproductive technology who were admitted to the reproductive center of the hospital from February 2019 to February 2020 were selected as the research objects.They were divided into group A(n=35),group B(n=36)and group C(n=36)with random touch ball method.Three groups were respectively set with different negative pressure suction pump pressures.Group A was 100 mmHg(1 mmHg=0.133 kPa),group B was 130mmHg,and group C was 160mmHg.The egg retrieval rate,high-quality embryo rate,fertilization rate,biochemical pregnancy rate,clinical pregnancy rate,number of needles,duration of puncture,and blood loss during puncture were compared among three groups.Results:The number of needle injections and puncture duration in Group B patients were(2.61±0.54)times and(9.87±2.14)minutes,respectively.The number of needle injections and puncture duration in group C patients were(2.47±0.39)times and(9.76±2.32)minutes,respectively,which were lower than those in group A(3.41±0.87)times and(13.21±3.74)minutes.The amount of bleeding during egg retrieval in Group C patients was(1.51±0.61)ml,which was higher than those in Group A and Group B(0.64±0.12)ml and(0.63±0.21)ml(P＜0.05).The high-quality embryo rate of group B patients(75.00%)was significantly higher than that of group A(51.43%)(P＜0.05).Conclusion:Setting a negative pressure of 130 mmHg during oocyte retrieval can increase the rate of high-quality embryos.Setting a smaller pressure can achieve higher operational safety.However,in clinical practice,pressure selection needs to be based on specific circumstances to achieve better pregnancy outcomes.
