目的探讨颅脑损伤患者的最佳吸痰方法。方法将颅脑损伤未建立人工气道的患者50例随机分为吸痰管刺激组25例和指压气管组25例，分别给予经口咽通气管吸痰和指压胸骨上窝后经口咽通气管吸痰，观察2组患者吸痰前及吸痰后3 min SpO2和RR变化、吸痰持续时间、吸痰间隔时间、有无恶心呕吐和气道粘膜出血的发生。结果两组RR变化、吸痰持续时间、吸痰间隔时间、恶心呕吐和气道粘膜出血例数比较，差异有统计学意义（P0.05）。结论利用口咽通气管，指压胸骨上窝刺激患者有效咳嗽后吸痰是颅脑损伤患者最佳的吸痰方法，此方法降低了并发症的发生，减轻了患者的痛苦，简单易行，值得临床推广。“,”Objective To investigate the best method of sputum suction for patients with craniocerebral injury. Methods Total y, 50 patients with craniocerebral injury without artificial airway were randomly divided into 2 groups: suction tube stimulus group in inoropharynx airway and pressing trachea group in inoropharynx airway after pressing suprasternal fossa, to observe the changes of SpO2 and RR before sputum suction and 3min after suptum sution, sputum suction duration, sputum suction time interval and the incidence of nausea and vomiting and airway mucosa blooding. Results Change of RR, sputum suction duration, sputum suction time interval and the incidence of nausea and vomiting and airway mucosa blooding were significantly dif erent(P0.05). Conclusion Aspiration of sputum by using inoropharynx airway, after pressing suprasternal fossa to cause patient to cough ef ectively, is the best method of sputum suction for patient with craniocerebral. This method decreace the incidence of complications, al eviate patient's pain, simple and practicable, be worthy of clinical promotion.
