To investigate the effects of perioperative continuous humidification on patients with laryngeal cancer undergoing tracheotomy.
Eighty patients with laryngeal cancer underwent tracheotomy in our hospital were selected as the subjects and divided into the observation group and the control group according to random table method. Patients in the control group were given routine tracheotomy care, including regular open endotracheal suction, tracheotomy nursing, oral care, dietary intervention, etc., while those in the observation group were given continuous airway humidification on the basis of the control group. The differences in sputum pH, viscosity, comfort, cough frequency, and respiratory ventilation were compared between the two groups at three postoperative time points. The incidence of complications such as pulmonary infection, bloody sputum and sputum crust, and the improvement of clinical symptoms were compared between the two groups.
The sputum pH of patients in the observation group was higher than that in the control group at the 4th and 7th postoperative days (<0.001). The observation group showed significantly lower percentage of grade 3 viscous sputum and higher comfort scores than the control group at the 7th postoperative day (=0.020, <0.001). The observation group showed lower cough frequency and higher airway patency than the control group at the 4th and 7th postoperative days (<0.001, <0.001, <0.001, =0.007).
Perioperative continuous airway humidification in patients with laryngeal cancer undergoing tracheotomy could reduce sputum consistency and cough frequency, improve comfort and respiratory patency of patients, and has positive significance in accelerating their postoperative rehabilitation.
探讨围手术期持续气道湿化对喉癌气管切开患者的影响。
选取我院行气管切开术的80例喉癌患者作为研究对象，按随机数字表法分为观察组和对照组。对照组给予常规气管切开护理，包括定期开放气管内吸痰、气管切开护理、口腔护理、饮食干预等，观察组在对照组基础上给予持续气道湿化。比较两组术后3个时间点痰液pH值、黏稠度、舒适度、咳嗽频率及呼吸通气情况。比较两组肺部感染、血性痰液及痰液结痂等并发症发生率及临床症状改善情况。
术后第4天和第7天，观察组患者痰液pH值高于对照组（<0.001）。术后第7天，观察组3度黏稠痰液比例显著低于对照组，舒适度评分高于对照组（=0.020，<0.001）。术后第4天和第7天，观察组咳嗽频率低于对照组，气道通畅度高于对照组（<0.001，<0.001，<0.001，=0.007）。
围手术期对喉癌气管切开患者进行持续气道湿化可降低痰液黏稠度和咳嗽频率，提高患者舒适度及呼吸通畅度，对加速其术后康复具有积极意义。
