Background: The endotracheal suction was one of the critical requirements for severe neurosurgical patients in the prevention of the airway-obstruction, pneumonia, atelectasis, and so on. There were two types of suction methods, closed and open. In the literature, many reported the comparison of the two methods with variable factors, yet, it was still controversial. In this study, we compared the two types of endotracheal suction methods based on the pattern of the sputum cultivation, which was not discussed in the previous studies.
Methods: In 2010, 85 patients who had intubation tube for more than 10 days were evaluated in this study. A total of 55 patients were managed with an open suction method, while the other 30 patients were managed with a closed suction method. All patients’ sputum culture was reported semi-quantitatively, and had been classified into 3 different groups, according to the culture pattern. The control group was defined in which the bacterial count was not increased, whereas the non-control group was those with bacterial count increased. We investigated patients’ age, gender, disease-type, suction techniques and the pattern of sputum cultivation.
Results: The non-control group was 45.45% in the open suction group, while it was 16.67% in the closed suction group. On the other hand, more control group was observed in the closed suction group (36.67%), than in the open suction group (25.45%) (p ＜ 0.05). There was no statistically significant difference in the analysis based on the pattern of sputum cultivation, age, gender, and disease-type.
Conclusions: We suggest that the closed suction methods were more effective in the management of endotracheal tube, according to the pattern of sputum culture.
