Effect of Invasive-noninvasive Sequential Mechanical Ventilation on Elderly Patients with Pulmonary Endogenous Acute Respiratory Distress Syndrome
Objective:To explore and analyze the clinical effect of invasive-noninvasive sequential mechanical venti-lation in the treatment of elderly patients with pulmonary endogenous acute respiratory distress syndrome(ARDS).Methods:From January 2022 to September 2023,60 elderly patients with pulmonary endogenous ARDS admitted to the Department of Critical Care Medicine of Dongguan Da Lang Hospital were randomly divided into control group(30 cases)and experimental group(30 cases).Both groups were given tracheal intubation and mechanical ventila-tion,while the control group was treated with tracheal intubation or tracheotomy,while the experimental group was treated with invasive-noninvasive sequential mechanical ventilation.The blood gas analysis indexes[including arte-rial partial pressure of oxygen(PaO2)and arterial partial pressure of carbon dioxide(PaCO2)]、invasive mechanical ventilation time、total ventilation time、ICU treatment time、incidence and mortality of ventilator-associated pneu-monia were compared between the two groups.Results:After treatment,compared with the control group,the PaO2 level in the experimental group was higher and the PaCO2 level was lower,P<0.05.Compared with the control group,the time of invasive mechanical ventilation、total ventilation and ICU treatment in the experimental group were shorter,P<0.05.Compared with the control group,the incidence and mortality of ventilator-associated pneumonia in the experimental group were lower,P<0.05.Conclusion:Invasive-noninvasive sequential mechanical ventilation is effective in the treatment of elderly patients with pulmonary endogenous ARDS,which can improve blood gas analysis indexes,relieve symptoms,shorten ventilation time and ICU treatment time,and reduce the incidence and mortality of ventilator-associated pneumonia.
