Comparison of application effects of closed and open sputum suction in airway nursing of patients with mechanical ventilation in emergency ICU
Objective:To compare application effects of closed and open sputum suction in airway nursing of patients with mechanical ventilation in emergency intensive care unit(ICU).Methods:The clinical data of 76 patients with mechanical ventilation admitted to the ICU of the hospital from January 2021 to January 2022 were retrospectively analyzed.According to different sputum suction methods,they were divided into control group and study group,38 cases in each group.The control group was treated with open endotracheal suctioning,while the study group was treated with closed endotracheal suctioning.The total amount of sputum suction and the mechanical ventilation time,the blood gas analysis indexes[arterial oxygen saturation(SaO2),arterial partial pressure of carbon dioxide(PaCO2),arterial partial pressure of oxygen(PaO2),respiratory rate,heart rate]levels,the incidence of mucosal injury,and the incidence of ventilator-associated pneumonia(VAP)were compared between the two groups.Results:The total amount of sputum suction in the study group was more than that in the control group,and the difference was statistically significant(P<0.05).The levels of SaO2 and PaO2 in the two groups were higher than those before sputum suction,and those in the study group were higher than those in the control group;the PaCO2 levels of the two groups were lower than those before sputum aspiration,and that in the study group was lower than that in the control group;the respiratory rate and heart rate of the two groups were higher than those before sputum aspiration,but those in the study group were lower than those in the control group;and the differences were statistically significant(P<0.05).Further,the incidence of airway mucosal injury and VAP in the study group were lower than those in the control group,and the differences were statistically significant(P<0.05).Conclusions:The closed endotracheal suctioning in the airway nursing of the ICU patients with mechanical ventilation can increase the total amount of sputum suction,improve the levels of blood gas analysis indexes,and reduce the incidence of airway mucosal injury and VAP.Moreover,it is superior to open endotracheal suctioning.
