ABSTRACT
Objective To investigate the pressure changes of cuff in the tapered-cuff endotracheal tubes and the frequency of cuff pressure monitoring in patient with trachea intubation. Methods From December 2016 to October 2017, 80 patients with oral tracheal intubation in the emergency department were divided into group A (n =25) and group B (n =23) according to the principle of randomized control. Group A with odd number was treated and tapered-cuff endotracheal tubes and group B with ever number and cylindrical-cuff endotracheal tubes. Continuous cuff pressure monitoring device was used to continuously monitor the cuff pressure. The two groups were compared in terms of time for keeping the normal cuff pressure and cuff pressure (average pressure, maximum pressure and minimum pressure). Results The total time for keeping the normal cuff pressure in group A was significantly shorter than that in group B (P＜0.05). The average cuff pressure in group A was smaller than that of group B (P＜0.05). The maximum pressure in group A is larger than that in group B and the maximum cuff pressure in group A was smaller than that of group B (P＜0.05). Conclusion Compared with the cylindrical cuff catheter, the tapered-cuff tube can maintain the normal pressure for a shorter period and easily produce needed pressure. It is a need to enhance the monitoring of cuff pressure to ensure good airway closure and reduce artificial airway complications.
ABSTRACT
The proto oncogene c-Myc is expressed in many kinds of organs, and its dysfunction is closely related to the occurrence and prognosis of lymphoma, prostatic cancer, breast cancer and pancreatic cancer.With a large number of studies focus on the expression and function of c-Myc in tumor, the treatment of tumor by targeting c-Myc has made a wealth of progress.
