目的研究分析机械通气时间长短与呼吸道疾病的相关性。方法资料数量表随机选取2002年1月—2011年4月在本院接受机械通气术治疗的56名新生儿患者,对其进行3年跟踪随访并实时记录随访资料,研究分析数据资料。结果机械通气治疗时间≤72h的患儿在定期回院复诊中呼吸道疾病的发生比率显著低于治疗时间>72h的患儿(P<0.05),差异具有统计学意义。结论新生儿机械通气时间的长短与远期呼吸道疾病的发生比率成正比,可能与长时间通气后导致支气管损伤及气道反应性增高有关。
Objective To study the relationship between the duration of mechanical ventilation and respiratory diseases. Methodology The data table was randomly selected from January 2002 to April 2011 in our hospital 56 cases of neonates undergoing mechanical ventilation were followed up for 3 years and real-time follow-up data were recorded to study and analyze data. Results The incidence of respiratory diseases in patients returning to hospital for mechanical ventilation less than or equal to 72 hours was significantly lower than that in patients who were treated for more than 72 hours (P <0.05). The difference was statistically significant. Conclusions The duration of mechanical ventilation in neonates is proportional to the incidence of long-term respiratory diseases, which may be related to bronchial injury and airway hyperresponsiveness after prolonged ventilation.
