Abstract:
Objective To investigate the effect on incidence of ventilator associated pneumonia(VAP),the cost of hospitalization with closed endotracheal suctioning and vital sign as well in postoperative cardiac patients.Methods 304 postoperative cardiac patients supporting by ventilation were enrolled in this cohort study during January,2012-November,2013 in The Second affiliated Hospital& Yuying Children Hospital of Wenzhou Medical University.All the subjects were randomly divided into observational group and control group by coin side.Closed endotracheal suctioning system was applied in observation group and opened mode was applied in control group.Compare the vital sign(heart rate,blood pressure,saturation) at the moment of aspiration,suction time,incidence of VAP,duration of ventilation,mortality,the cost of suction,hospital stays and hospitalization expense.Results The baseline is no significant difference between two groups.The fluctuation of blood pressure and heart rate is lower in observational group at 30 second since completed the suction(P ＜0.05),but saturation is higher at 30 second and 60 second since completed the suction respectively(P ＜ 0.05).There is no significant difference of incidence of unexpected tube displacement and pneumothorax between two groups.Average time of each suction of experimental groups is shorter than Control groups[(156 ± 6) s vs (225 ± 8) s,t =-84.86,P ＜ 0.01].VAP incidence is lower in experimental group (12.0％ vs.18.6％,x2 =4.37,P ＜ 0.05).Duration of ventilation is lower in experimental group[(72 ± 33) h vs.(98 ± 38) h,t =-6.35,P ＜ 0.05].The cost of suction is higher in observational group [(346 ± 15) RMB vs.(178 ± 26) RMB,t =69.00,P ＜ 0.01],but the hospitalization expense is lower in experimental group [(32 011 ± 2 525) yuan vs.(35 264 ± 3 846)yuan,t =-8.72,P ＜ 0.05].There is no significant difference in mortality between two groups (x2 =0.08,P ＞ 0.05).Conclusion Application of closed endotracheal suction system can result in reduction vital sign fluctuation and incidence of cross infection and reducing the workload of nurses and decreasing the complication of suction,shorting the duration of ventilation and hospitalization and saving the expense of hospitalization in postoperative cardiac patients comparing with open mode.It is worthy to be populized in cardiac care unit.
