腹部手术前后血气分析及肠道菌群变化

目的:探讨围手术期腹部外科病人血气和酸碱平衡、肠道菌群变化及临床意义.方法:随机检测100例腹部外科择期手术患者术前和术后血气分析.同时对术后发生腹泻的13例患者行粪便菌群分析.结果:手术后低血氧27例,而胃癌根治、直肠癌根治、肝叶切除等大手术者均有不同程度酸碱失衡,且发生酸碱失衡者中9例合并菌群失调.结论:具有高危因素的腹部手术患者,术前及术后检测血气,监测肺功能及酸碱平衡,并积极诊治肠道菌群失调.

Changes of arterial blood gases and before and after abdominal surgery

Objective:To investigate the changes of arterial blood gases and microflora disorder in patients before and after abdominal surgery Methods:100 randomly selected abdominal surgery patients were enrolled,of wfich arterial blood gases were measured prior to and after surgery.Results:Before surgery 27 cases,mainly aged people,occurred anoxia which were unconcerned in original diseases;19 cases occurred metabolic acidosis;13 cases occurred metabolic alkalosis.27 cases occurred anoxia post operation Among 13 patients with postoperative diarrhea,there were 9 patients with microflora disorder complicated with acid base imbalance.Conclusion:We should measure blood gases and electrolyte in aged patients ready to undergo abdominal surgery before and after operation and try best to diagnosis and treat with postoperative microflora disorders.
