Objective To investigate the clinical value of bronchofibroscope to the patients with respiratory failure treated by mechanical ventilation. Methods 44 patients with respiratory failure treated by mechanical venti-lation who were rescued with bronchofibroscope in EICU from January 2006 to June 2007 were compared the days of antibiotic application, the days of mechanical ventilation and mortality rate with 35 patients with respiratory failure treated by mechanical ventilation but not using bronchofibroscope during January 2005 to January 2006. Results Compared with the control group, the therapy group had fewer days of antibiotic application, fewer days of mechani-cal ventilation and lower mortality rate(P < 0.05). During absorbing expectoration with bronchofibroscope, compli-cation such as haemorrhage did not happen. Conclusion Bronchofibroscope application in the patients with respira-tory failure treated by mechanical ventilation can shorten the time of mechanical ventilation and cut down the mortal-ity rate,which was worth generalizing in clinical work.

Objective:The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China.Methods:This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems.Results:According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%).Conclusion:Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.
