Objective To analyze the advantages of modified retrograde endotracheal intubation and to investigate its application effect in difficult airway opening. Methods Eighteen patients with difficult airways receiving modified retrograde endotracheal intubation admitted to Jinhua Municipal Central Hospital from June 2013 to June 2017 were enrolled. The successful intubation rate, complication rate, average intubation time and typical cases were calculated and analyzed. Results The causes of airway difficulty in 18 patients: there were 7 patients with glottis exposing difficulty due to tongue body hypertrophy, 2 patients with trismus due to tetanus, 5 patients with cervical spinal cord injury and 4 patients with burns. The successful rate of modified retrograde endotracheal intubation was 100% in 18 patients with difficult airway. Only 1 patient had a little bleeding at the puncture site and it was improved after local compression, the complication rate being 5.6% (1/18), and the average intubation time was (3.6±0.8) min. Conclusion Modified retrograde endotracheal intubation is a method easy to be mastered, its material is simple and easily to be acquired, clinically, the successful rate in its application in difficult airway patients is very high and its incidence of complication is very low, so that the technique can be popularized in primary hospitals.

Objectives:To compare the effects of manual and mechanical chest compression on patients receiving extracorporeal cardiopulmonary resuscitation (ECPR).Methods:Patients who underwent extracorporeal cardiopulmonary resuscitation admitted to Jinhua Municipal Central Hospital, Hangzhou First People's Hospital and the First Hospital of Jiaxing from September 2014 to July 2022 were enrolled in the study. The patients were divided into the manual group and mechanical group according to the compression method, and the clinical data of the two groups were compared. To explore the effects of the two compression method on the ECPR implementation, proportion of return of spontaneous circulation (ROSC) and hospital survival.Results:A total of 108 patients who underwent ECPR were included in the study, 50 patients in the manual group and 58 patients in the mechanical group. There were no significant differences in sex, age, laboratory tests before ECPR, ROSC proportion (90.0% vs. 86.2%) and survival (34.0% vs. 39.7%) between the two groups (all P>0.05). The puncture time in the mechanical group was shorter than that in the manual group [12 (9,15) min vs. 13 (11,16) min, P<0.05]. Conclusions:Compared with manual compression, mechanical compression during ECPR neither increase the probability of ROSC nor reduce in-hospital mortality in patients with cardiac arrest. However, mechanical compression may help to shorten the puncture time.
