Abstract:
Objective To explore the effect of 0.9％ sodium chloride solution airway instillation before endotracheal suctioning on machinery ventilates patients.Methods Totals of 80 patients who received mechanical ventilation longer than 72 hours were enrolled in this study and were randomly divided into experimental group and the control group with 40 cases each group.And 5ml 0.9％ sodium chloride solution was instilled into the airway of each case in experimental group before the endotracheal suctioning,while the same procedure was not performed in control group.The incidence of VAP,the positive rate of sputum culturing,themechanical ventilation time and the staying time in ICU were observed and respectively compared between the two groups.Results The incidence of VAP was 25.0％ in experimental group and 15.0％ in control group,and the difference was no statistically significance(P ＞0.05).The positive rate of sputum culturing was 47.5％ in experimental group,while that was 22.5％ in control group,and the difference was statistically significant( x2 =5.495,P ＜ 0.05 ).The mechanical ventilation time and the staying time in ICU of experimental group respectively were higher than that of control group [ ( 7.35 ± 3.89 ) vs( 5.73 ± 2.45 ),( 10.88 ± 4.37 ) vs(9.00 ± 3.59 ) ],and the difference was statistically significant ( U =602.0,589.5,respectively ; P ＜ 0.05 ).Conclusions Airway instillation of 0.9％ sodium chloride solution before endotracheal suctioning can increase the positive rate of sputum culturing,mechanical ventilation time,and the staying time in ICU for patients,so it should not be performed as a routine nursing procedure.
