ABSTRACT
OBJECTIVE@#In the context of coronavirus disease 2019 (COVID-19) pandemic, the subject was designed to develop a new tracheal intubation device based on magnetic navigation technology to improve the success rate of tracheal intubation and reduce the risk of occupational exposure of medical staff.@*METHODS@#The new tracheal intubation device was designed with the uniqueness of the magnetic field environment and magnetic steering of magnetic navigation technology. And preliminary magnetic navigation tracheal intubation experiments were performed on the tracheal intubation simulator.@*RESULTS@#Magnetic navigation tracheal intubation can successfully implement tracheal intubation, and the time required is lower than that of traditional laryngoscopy.@*CONCLUSIONS@#The tracheal intubation based on magnetic navigation technology is feasible, with high efficiency and easy operation. That is expected to be widely used for tracheal intubation during treatment of patients outside the hospital in the future. At the same time, magnetic navigation endotracheal intubation technology will be the key technology for the development of endotracheal intubation robots.

Objective:To review experience on the diagnosis and treatment of patients with pancreatic injury.Methods:There were 65 patients with pancreatic injuries who were managed in the First Affiliated Hospital of Xi’an Jiaotong University between January 1995 and December 2017. After excluding 6 patients with inadequate data and 4 patients with other associated injuries, the remaining 55 patients were enrolled in this retrospective study. All data, including the type of abdominal trauma, general information of patients, clinical manifestations, methods of diagnosis, treatment, operation and complication were collected and analysed. Analyze the cause, degree of injury, treatment measures, treatment results and complications of patients with pancreatic injury.Results:The most common cause of pancreatic injury was traffic accidents (23 patients, 41.8%), with a correct preoperative diagnostic rate of 61.8% for pancreatic injury. Compute tomography (CT) had a significantly higher sensitivity than sonography (80% vs. 37.5%, P<0.05). The number of patients with grade I-V pancreatic injury were 7, 19, 24, 1 and 4, respectively. Sixteen patients were successfully managed by conservative treatment, and 39 patients underwent various surgeries depending on the injury grade. Significantly more patients having severe grades (III-V) underwent surgical treatment than those having mild grades (I-II) (53.8% vs. 86.2%, P<0.05). Two patients died after surgery (mortality rate 5.1%, 2/39). Pancreatic fistula developed in 29 patients (74.4%), intra-abdominal infection in 10 patients (25.6%) and these were the main surgical complications. Patients having severe grades had a significantly higher pancreatic fistula rate than those having mild grades. Pancreatic pseudocyst was the most common complication on long-term follow-up (8 patients, 14.5%). This complication was significantly higher in patients who were managed with consecutive treatment than with operation (31.2% vs. 7.7%, P<0.05). Conclusions:The preoperative diagnosis of pancreatic injury was difficult, and CT should be the first line investigation. Grade I -II injuries could be managed by conservative treatment, while grade III-V should be treated by operations. The most common short- and long-term complications of pancreatic injury were pancreatic fistula and pancreatic pseudocyst, respectively.
ABSTRACT
Metabolic disorder is one of the most obvious pathophysiological characteristics of patients with severe burn or trauma, which leads to high mortality of patients with severe burn or trauma. Metabonomics is a newly developed subject which provides new research concepts and ideas for studying the changes of metabolism in a disease condition. Based on the analysis of group indicators, metabonomic technique not only can systematically study the change rules of metabolites, which helps to further clarify the pathophysiological mechanism of burn or trauma, but also is helpful to find some significant biomarkers with important clinical value so as to provide new insight for the therapy of burn or trauma. This paper reviews the research progress of application of metabonomics in the treatment of severe burn or trauma in recent years.
ABSTRACT
Objective To evaluate the application effect of telemedicine robot on the postoperative follow-up of liver transplantation recipients from donation after cardiac death (DCD). Methods A total of 100 recipients undergoing liver transplantation from DCD in the First Affiliated Hospital of Xi 'an Jiaotong University from January 2014 to December 2017 were recruited in this investigation. According to differnt follow-up patterns, all recipients were divided into the research group (n=50, follow-up by telemedicine robot) and control group (n=50, follow-up by traditional telephone). The compliance (medication compliance, self-monitoring, life compliance and follow-up compliance), follow-up time and follow-up satisfaction at postoperative 3 months of all DCD liver transplantation recipients were analyzed and statistically compared between research group and control group. Results The scores of medication compliance, self-monitoring, life compliance, follow-up compliance and the total score of compliance in the research group were significantly higher than those in the control group (all P < 0.05). The each follow-up time of liver transplantation recipients in the research group was (9±4) min, significantly shorter than (13±4) min in the control group (t=-4.452, P < 0.001). The score of satisfaction during postoperative follow-up in the research group was 19.8±2.6, significantly higher than 16.2±3.1 in the control group (t=6.234, P < 0.001). Conclusions The application effect of telemedicine robot on the postoperative follow-up of liver transplantation recipients from DCD is satisfactory, deserves widespread application in clinical practice. It is expected to become an indispensable part of the postoperative follow-up of liver transplantation recipients from DCD.
