目的:探讨动脉血气分析检测在胸部肿瘤病人围手术期的应用及其变化与心肺功能并发症发生的关系。方法:分别检测胸部肿瘤病人术前1周内,术后2h、8h以及第1、2、3d,第4d或第5d的动脉血气,对所检测数据进行统计学处理并与术后心肺并发症发生作相关性进行分析。结果:围手术期血气分析统计资料显示胸部肿瘤病人手术后第2天动脉血氧分压最低(P<0.01),二氧化碳分压最高,低氧血症造成手术后心肺并发症的发生率也高(P<0.05)。结论:围手术期血气分析的变化与手术后心肺功能并发症的发生有关,为减少手术后心肺功能并发症的发生和保证围手术期的安全,要注意保持呼吸道通常,并给予充分的氧疗以纠正低氧血症,必要时应用呼吸机辅助呼吸。
Objective: To investigate the application of arterial blood gas analysis in the perioperative period of chest cancer patients and its relationship with the occurrence of cardiovascular complications. Methods: The arterial blood gas of patients with chest tumor within 1 week, 2h, 8h, 1, 2, 3d, 4d or 5d after operation were detected respectively. The data were statistically analyzed and compared with postoperative cardiopulmonary complications Relevant for analysis. Results: Perioperative blood gas analysis showed that the lowest partial pressure of arterial oxygen (P <0.01), the highest partial pressure of carbon dioxide and the incidence of postoperative cardiopulmonary complications caused by hypoxemia (P <0.05). Conclusion: Perioperative blood gas analysis changes with the incidence of postoperative cardiopulmonary complications, in order to reduce the incidence of postoperative cardiopulmonary complications and ensure perioperative safety, we should pay attention to maintain the respiratory tract and give adequate oxygen therapy To correct hypoxemia, ventilator-assisted breathing if necessary.
