Abstract
Objective To explore the application efficacy of micro cleansing instrument-assisted vibration sputum elimination in neonatal pneumonia. Methods A total of 62 neonates diagnosed with pneumonia admitted to the Department of Neonatology from August 2025 to January 2026 were enrolled and divided into an observation group (33 cases) and a control group (29 cases). Both groups of neonates received conventional comprehensive treatment and basic nursing. The control group received manual sputum elimination, while the observation group received sputum elimination intervention assisted by a micro cleansing instrument based on manual sputum elimination. Arterial blood gas indicators (SaO2, PaO2, PaCO2), heart rate, respiratory rate before and after intervention, the improvement time of clinical symptoms (cough, pulmonary rales, tachypnea), and the incidence of adverse reactions were compared between the two groups. Results The observation group had lower PaCO? than the control group, while SaO? and PaO? were higher than those in the control group, and between-group differences were statistically significant (P＜ 0. 01). The observation group had better outcomes of respiratory rate and heart rate compared with those in the control group (P＜0. 05). The time to relief of neonatal pneumonia symptoms (cough, pulmonary rales, tachypnea) in the observation group was shorter than that in the control group, with a significant difference(P＜0. 05), There was no significant difference in incidence of adverse reactions between the two groups (P＞0. 05). Conclusion Micro cleansing instrument-assisted vibration sputum elimination can effectively improve outcomes of arterial blood gas testing, stabilize heart rate and respiratory rate, and shorten the relief time of clinical symptoms in neonates with pneumonia without increasing the risk of adverse reactions. It is worthy of clinical application. (目的 探讨微型洁面仪辅助振动排痰在新生儿肺炎护理中的应用效果。方法 将2025年8月—2026年1月新生儿科收治的肺炎患儿62例分为观察组(n=33)和对照组(n=29)。两组患儿均接受常规综合治疗与基础护理。对照组实施人工排痰方案, 观察组在对照组基础上实施微型洁面仪辅助振动排痰方案。比较两组患儿动脉血气分析指标［动脉血氧饱和度(SaO2)、动脉氧分压(PaO2)、动脉二氧化碳分压(PaCO2)］、心率及呼吸频率、临床症状(咳嗽、肺部啰音、气促)改善时间及不良反应发生率。结果 干预后, 观察组PaCO2水平较对照组降低, SaO2和PaO2高于对照组, 差异有统计学意义(P＜0. 01)。干预后, 两组呼吸和心率情况均有所改善, 且观察组优于对照组, 差异有统计学意义(P＜0. 05)。观察组患儿肺炎症状改善时间(咳嗽、肺部啰音、气促)较对照组缩短, 差异有统计学意义(P＜0. 05)。两组不良反应发生率比较, 差异无统计学意义(P＞0. 05)。结论 微型洁面仪辅助振动排痰可有效改善新生儿肺炎患儿的动脉血气指标, 稳定心率及呼吸频率, 缩短临床症状改善时间, 且不增加不良反应风险, 具有一定的临床应用价值。)
