Observation of the use of percutaneous tracheostomy tube for closed drainage of pneumothorax in intensive care unit

Abstract

To explore the effect of the transcutaneous tracheostomy tube in patients with pneumothorax and its clinical value. A prospective randomized controlled trial was conducted. Thirty-two patients with pneumothorax admitted to Department of Critical Care Medicine of Harrison International Peace Hospital of Hebei Medical University from June 2010 to June 2014 were enrolled. The patients were divided into control group and observation group, with 16 cases in each group. Beside the treatment for primary disease, the patients in control group received thoracic close drainage with traditional silica gel tube as performed by thoracic surgeons, and those in observation group received thoracic close drainage with transcutaneous tracheostomy tube by intensive care doctors. The curative effect and complications of the two groups were observed. Compared with control group, the time from diagnosis to operation (minutes:8.00 ± 1.36 vs. 23.06 ± 3.83, t=14.790, P=0.000) and the operation time were significantly shortened (days:5.37 ± 1.02 vs. 7.31 ± 1.70, t=7.286, P=0.000), the frequency of drainage tube replacement (times: 0.18 ± 0.40 vs. 3.87 ± 1.14, t=12.128, P=0.000) and the times of repeated chest radiography (times:1.12 ± 0.34 vs. 2.93 ± 0.77, t=8.589, P=0.000) in observation group were significantly reduced, the length of hospital day was significantly shortened (days:8.30 ± 1.37 vs. 24.56 ± 5.62, t=17.289, P=0.000), the rates of dislocation of drainage tube (0 vs. 3 cases), obstruction of the tube (0 vs. 5 cases), and subcutaneous emphysema (3 vs. 16 cases) were reduced obviously, but there was no difference in incidence of incision infection (1 vs. 3 cases) and infection of thoracic cavity (0 vs. 2 cases). The usage of transcutaneous tracheostomy tube in patients with pneumothorax is safe and simple. Doctors in ICU can independently do this procedure, and its effect is positive.
