Analysis of the preventive effect of early activities combined with airflow shock method on ventilator associated pneumonia in patients with acute exacerbation of chronic obstructive pulmonary disease undergoing mechanical ventilation
Objective To analyze the preventive effect of early activities combined with airflow shock therapy on ventilator associated pneumonia(VAP)in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)undergoing mechanical ventilation.Methods A total of 90 AECOPD patients admitted from May 2021 to May 2023 were prospectively enrolled in a randomized controlled study.They were divided into control group and observation group by random number table method,with 45 cases in each group.Patients in both groups received routine interventions combined with airflow shock method during mechanical ventilation,while those in the observation group were additionally managed by early activities.Interventions were given until extubation.The incidence of VAP(case number of VAP and time of VAP),length of stay,mechanical ventilation time and adverse events(catheter translocation,blockage,airway injury,pressure sores,extubation failure)during treatment were compared between the two groups.The preventive effect of early activities combined with airflow impact on VAP in AECOPD patients with mechanical ventilation was discussed.Results Significantly lower incidence and shorter duration of VAP were detected in the observation group than those of the control group(P＜0.05).The length of stay and mechanical ventilation time of the observation group were significantly shorter than those of the control group(P＜0.05).There was no significant difference in the total incidence of adverse events between the two groups during the treatment period(P＞0.05).Conclusion Early activities combined with airflow shock therapy can effectively prevent VAP in AECOPD patients undergoing mechanical ventilation,shorten length of stay and mechanical ventilation time,and promote a better disease recovery.
