Abstract:

Sixty-eight cases with tuberculous pleurisy, who were treated by closed thoracic drainage with single vena cava catheter in the Tangshan Branch of the Second Hospital of Nanjing from June 2017 to January 2018, were selected as the subjects of this study. The subjects were divided into experimental group (33 cases) and control group (35 cases). The experimental group used self-made pleural cannula dressing to fix the closed thoracic drainage tube, while the control group used conventional transparent dressing. The comfort score of the experimental group was (2.42±0.56), which was significantly higher than that of the control group (2.06±0.48); there was a statistically significant difference (t=-2.89,P=0.005). The dressing interval of the experimental group was (7.00±1.23)d, significantly longer than that of the control group (3.77±1.33)d, and the difference was statistically significant (t=-10.49,P<0.01). The unplanned extubation rate in the control group was 11.4% (4/35), and there was no unplanned extubation in the experimental group. The difference between the two groups was statistically significant (χ ²=5.55,P=0.018). The self-made pleural cannula dressing has obvious clinical effects in terms of comfort, frequency of dressing change and preventing unplanned extubation.
