目的：为保证肿瘤病人围术期的安全应进行全面的呼吸管理。因麻醉过程中病人的呼吸容易受到干扰，促使对麻醉时的呼吸管理要求更高。方法：胸科肿瘤手术175例，ASAⅠ－Ⅳ级，静脉间断注射芬太尼，卡肌宁及吸入恩氟烷复合麻醉，常规监测心率、血压、吸入恩氟烷浓度，脉博氧饱和度（SpO2）及呼末二氧化碳分压（Pet－CO2）。结果：175例全麻病人诱导插管均成功，术中各项监测指标稳定，术后拔管顺利。结论：作好术前准备，加强术中观察，严格掌握拔管指征是保证病人安全的重要关键。
OBJECTIVE: To provide comprehensive respiratory management to ensure the safety of tumor patients during perioperative period. The patient’s breathing is easily disturbed during the anesthesia, which leads to higher requirements for respiratory management during anesthesia. Methods: 175 cases of thoracic surgery were performed with ASAI-IV grade, intravenous fentanyl, carnitine and inhaled enflurane combined anesthesia. Routine monitoring of heart rate, blood pressure, inhaled enflurane concentration, pulse oximetry ( SpO2) and end-tidal carbon dioxide partial pressure (Pet-CO2). RESULTS: All 175 patients with general anesthesia were successfully intubated. All monitoring indicators were stable during the operation, and postoperative catheter removal was successful. Conclusion: Preoperative preparation, strengthening intraoperative observation, and strict control of extubation indications are important keys for ensuring patient safety.
