目的:探究全身多发烧伤患者术中突发血氧饱和度下降的原因。方法:以我院接受治疗的一例全身多发烧伤患者为研究对象,观察患者术中及术后情况。结果:患者术前便有低氧血症,氧合指数较差,但在酒精消毒后低氧血症症状突然加重,且有循环的改变,采取相应措施后患者的低氧血症得到了控制。结论:烧伤后低氧血症为烧伤后常见并发症,烧伤手术过程中由于补液,呼吸机等一系列综合因素作用下,患者易出现低氧血症,严重威胁患者生命健康,因此要及时采取有效的措施予以缓解。 OBJECTIVE: To investigate the causes of sudden oxygen saturation decline in patients with systemic multiple burns. Methods: A case of systemic multiple burn patients undergoing treatment in our hospital was studied. The intraoperative and postoperative conditions were observed. Results: Patients had hypoxemia preoperatively and poor oxygenation index. However, the symptoms of hypoxemia suddenly increased after alcoholic disinfection and there was a cyclic change. Hypoxemia was controlled after the corresponding measures were taken . Conclusion: Post-burn hypoxemia is a common complication after burn. Due to a series of comprehensive factors such as rehydration and ventilator during burn operation, patients are prone to hypoxemia and seriously threaten the life and health of patients. Therefore, timely take Effective measures to be eased.
