To report the decreased IVF rate of oocytes and the reduced cleavage rate of pronuclear stage embryos after gas has backflowed from a gas analyzer into an incubator during the calibration of the CO(2) concentration.
Case report.
Clinical research unit for reproductive medicine in a hospital.
INTERVENTION(S): Backflow of gas from a gas analyzer into an incubator during calibration of the CO(2) concentration.
The IVF rate of oocytes and the cleavage rate of pronuclear stage embryos.
RESULT(S): Thirty-two oocytes were retrieved from four infertile female patients. Nine oocytes were fertilized and four fertilized oocytes were cleaved. In a related animal experiment, the cleavage rate was 57.1% (36/63) in the control group and 25.4% (16/63) in the study group (P =.00026).
CONCLUSION(S): The backflow of gas from the gas analyzer adversely affected the fertilization of oocytes and the cleavage of pronuclear stage embryos.
报告在二氧化碳浓度校准期间,气体分析仪中的气体回流至培养箱后,卵母细胞体外受精(IVF)率降低以及原核期胚胎卵裂率下降的情况。

在二氧化碳浓度校准期间,气体从气体分析仪回流至培养箱。
卵母细胞的体外受精率和原核期胚胎的卵裂率。
从4名不孕女性患者中获取了32枚卵母细胞。9枚卵母细胞受精,其中4枚受精卵发生卵裂。在一项相关动物实验中,对照组的卵裂率为57.1%(36/63),研究组为25.4%(16/63)(P = 0.00026)。
气体分析仪中的气体回流对卵母细胞的受精和原核期胚胎的卵裂产生了不利影响。
