Patients with tracheotomy are often monitored in the anesthesia recovery room after reoperation. During this period, oxygen therapy is necessary, and the existing tracheostomy oxygen supply device has many defects.
To evaluate the efficacy of a self-made tracheostomy oxygen delivery device on oxygen therapy during postoperative anesthesia recovery.
Patients were randomly divided into two groups, E and C, with 30 patients in each group, and admitted to the post-anesthesia care unit (PACU). Patients in group E received oxygen through a self-made tracheostomy oxygen delivery device, while patients in group C were supplied oxygen through a unilateral nasal cannula. Respiration (R), pulse oximetry (SpO2), and the number of patients on ventilators were recorded at the time of admission (T0) and one hour after admission (T1). Rapid dry blood gas analyses were performed on 0.6 ml samples of arterial blood collected at T0 and T1.
Compared to group C, patients in group E had significantly higher arterial partial pressure of oxygen (PaO2), arterial oxygen saturation (SaO2), total carbon dioxide (T-CO2), and actual bicarbonate (AB), while arterial partial pressure of carbon dioxide (PaCO2) was significantly reduced (P< 0.01 or < 0.05). Compared to T0, PaO2 decreased in both groups at T1, PaCO2 decreased in group E, while SaO2, T-CO2, and AB decreased in group C (P< 0.01 or < 0.05).
We found that using the self-made tracheostomy oxygen delivery device in postoperative anesthesia recovery had advantages such as a secure connection to the tracheostoma, adjustable oxygen concentration, air filtration, and the ability to switch oxygen supply between the ventilator and humidifier.
气管切开患者再次手术后常在麻醉恢复室进行监测。在此期间，氧疗是必要的，而现有的气管切开给氧装置存在诸多缺陷。
评估自制气管切开给氧装置在术后麻醉恢复期间氧疗的效果。
将患者随机分为E组和C组，每组30例，收入麻醉后监护病房（PACU）。E组患者通过自制气管切开给氧装置吸氧，C组患者通过单侧鼻导管吸氧。在入院时（T0）和入院1小时后（T1）记录呼吸（R）、脉搏血氧饱和度（SpO2）及使用呼吸机的患者数量。对在T0和T1采集的0.6 ml动脉血样本进行快速微量血气分析。
与C组相比，E组患者的动脉血氧分压（PaO2）、动脉血氧饱和度（SaO2）、总二氧化碳（T-CO2）和实际碳酸氢盐（AB）显著升高，而动脉血二氧化碳分压（PaCO2）显著降低（P<0.01或<0.05）。与T0相比，两组在T1时PaO2均降低，E组PaCO2降低，而C组SaO2、T-CO2和AB降低（P<0.01或<0.05）。
我们发现，在术后麻醉恢复期间使用自制气管切开给氧装置具有与气管造口连接牢固、氧浓度可调节、空气过滤以及能够在呼吸机和湿化器之间切换供氧等优点。
