This study was conducted to evaluate the different change in arterial blood gases and cardiovascular system in 50 healthy females during laparoscopic sterilization procedure performed under general or local anaesthesia. Women who had laparoscopic sterilization under local anaesthesia, showed an increase in respiratory rate by 17% in response to hypercarbia produced by carbon dioxide insufflation. Subjects undergoing laparoscopic sterilization under general anaesthesia showed significant rise in pulse rate by 6% and systolic and diastolic blood pressure by 8% and 14%, respectively. Also arterial blood gas analysis showed increase in PaO2 by 22.7% which was highly significant. However, PaCO2, pH and base were maintained within normal limits as compared to the other group done under local anaesthesia, where no changes were observed.
本研究旨在评估50名健康女性在全身麻醉或局部麻醉下进行腹腔镜绝育手术期间动脉血气和心血管系统的不同变化。在局部麻醉下进行腹腔镜绝育手术的女性，由于二氧化碳气腹产生的高碳酸血症，呼吸频率增加了17%。在全身麻醉下进行腹腔镜绝育手术的受试者脉搏率显著上升6%，收缩压和舒张压分别上升8%和14%。此外，动脉血气分析显示动脉血氧分压（PaO2）升高22.7%，具有高度显著性。然而，与在局部麻醉下进行的另一组相比，动脉血二氧化碳分压（PaCO2）、pH值和碱剩余保持在正常范围内，该组未观察到变化。
