Abstract:
Objective To explore the effect of the open and closed endotracheal suction on the infection prevention and control among adults after cardiac surgery.Methods Totals of 159 patients after cardiac surgery with mechanical ventilation were randomly divided into the closed suction group (n =77 ) and the open suction group (n =82).There was no significantly difference in the average ages,gender composition,disease composition between two groups.The white blood cell (WBC) count of two groups in the day and the first,second and third days after surgery,the positive rate of sputum culture before extubation,and total duration time of mechanical ventilation of two groups were observed and compared,respectively.Results The WBC count of closed suction group in the day and the first day was ( 10.42 ± 3.81 ) × 109/L,( 12.03 ± 3.87 ) × 109/L and that of the open suction group was (9.44 ± 3.36) × 109/L,( 11.32 ± 3.59) × 109/L,and the difference was no statistically significant( P ＞0.05 ).There was significantly difference in the WBC between closed suction group and open suction group in second and third days after surgery[ (16.14±5.78) × 109/L vs (14.81 ±3.68) × 109/L),( 15.09 ± 5.91 ) × 109/L vs ( 12.65 ± 3.18 ) × 109/L;t =- 2.044,- 2.409,respectively; P ＜ 0.05 ) ].The positive rate of sputum culture showed no difference between closed suction group and open suction group ( 12.2％ vs 10.4％ ; x2 =0.129,P ＞ 0.05 ),and the total mechanical ventilation time of the closed suction group was significantly longer than that of the open suction group [ ( 14.48 ± 4.71 ) h vs ( 12.15 ± 4.47 ) h ;t =2.994,P ＜ 0.05 ) ].Conclusions The effect of open endotracheal suction is better than closed suction in the mechanical ventilation patients after cardiac surgery,and it is not expensive than closed suction for the patients with short period mechanical ventilation.
