Objective To explore the effectiveness and safety of self-made washable endotracheal tube for subglottic secretion drainage. Methods Ordinary endotracheal tube and sputum aspirating tubes were used to make washable endotracheal tube for subglottic secretion drainage in our hospital. The self-made tubes were compared with washable endotracheal tube available on the market. The suction resistance, the cases of obstruction in the tubes, the average daily drainage, and the cases of infection of incisional wound were compared between the two kinds of tubes, and their safety was evaluated. Results After three days of application, the suction resistance of endotracheal tube available on the market increased, with six cases of the blockage of the lumen ( 85% ) , while that of self-made endotracheal tube did not change, with no cases of blockage ( 0% ) . There was significant difference between these two kinds of tubes ( P lt;0. 01) . The average daily drainage in the former was ( 16. 55 ±8. 66) mL/d; while that in the latter was ( 40. 12 ±25. 48) mL/d. There was no significant statistical difference between the two kinds of tubes ( P gt;0. 05) . The incidence ofinfection of incisional wound in the ordinary endotracheal tube was 50% ( 5 cases) ; that in the tubes available on the market was 28% ( 2 cases) ; that in the self-made tubes was 15% ( 2 cases) . There was significant difference among the three groups. When tube cuffs were inflated, the distance between the back edge of suction tubes and tube cuffs was was 2-4 mm. Conclusion Self-made washable endotracheal tubes are effective for subglottic secretion drainage with good safety and low price.
Objective To explore the influence of different withdrawal time of trachea cannula on percutaneous dilational tracheostomy (PDT) in critically ill patients. Methods In this study, we retrospectively analyzed the clinical data of 185 critically ill patients experienced PDT, who had been admitted to the adult mixed ICU of Xiaolan Hospital of Southern Medical University from January 2015 to July 2017. The patients were divided into an early PDT group (EPDT group) and a delayed PDT group (DPDT group) according to the timing of withdrawing trachea cannula. Operation information such as operation time, blood loss and the incidence of complications were collected and compared between the two groups. Results Between the EPDT group and the DPDT group, there were no obvious differences in operation time (minutes: 6.5±2.6 vs. 7.3±3.5), amount of blood loss (ml: 5.2±2.8 vs. 6.0±3.4) or conversion to traditional operation (1.9% vs. 2.4%) (all P>0.05). Compared with the EPDT group, the DPDT group patients experienced more fluctuation of intraoperative vital signs, used more dose of sedative and analgesic drugs, and experienced higher occurrence of aspiration (18.3%vs. 5.6%), balloon burst (13.4% vs. 2.9%), guide-wire placing difficulty (11.0% vs. 1.9%) and tracheostomy cannula placing difficulty (14.6% vs. 2.9%) (all P<0.05). There were no statistical significances in postoperative complications such as postoperative-hemorrhage, pneumothorax, pneumoderm, the posterior tracheal injury or incision infection between the two groups (allP<0.05). More patients acquired postoperative pulmonary infection in the DPDT group than the EDPD group (12.2%vs. 5.8%, P>0.05), and there was no statistical significances in mechanical ventilation time between the two groups (days: 5.5±3.0vs. 6.0±2.5, P>0.05). Conclusions The operation and complications of PDT in critically ill patients are influenced by the timing of withdrawing trachea cannula. The standard procedure of withdrawing trachea cannula preoperatively may offer better clinical operability and lower technical risk.
