Abstract
Objective To introduce a new modified percutaneous dilational tracheostomy and compare the application effect of percutaneous dilational tracheostomy with modified percutaneous dilational tracheostomy in the treatment of critically ill patients. Methods A total of 60 critically ill patients undergoing tracheotomy were selected, and they were randomly divided into two groups according to the methods of tracheotomy. Sex, age, weight, body mass index, acute physiology and chronic health evaluation, operation time, incision size, intraoperative blood loss, incision healing time, incidences of complications after operation were compared between the two groups. Results There were not statistically significant differences of in sex, age, weight, body mass index, and acute physiology and chronic health evaluation between percutaneous dilational tracheostomy group and modified percutaneous dilational tracheostomy group (P>0.05). Operation time, incision size and intraoperative blood loss of modified percutaneous dilational tracheostomy group was statistically significantly shorter than that of percutaneous dilational tracheostomy group [(5.80 ± 1.19) min vs. (7.65 ± 1.05) min, (8.33 ± 3.30) ml vs. (11.33 ± 4.34) ml, (1.08 ± 2.96) cm vs. (1.27 ± 2.54) cm](P 0.05). Conclusions The modified percutaneous dilational tracheostomy can save operation time, and reduce intraoperative blood loss, so it can be widely used. Key words: Tracheostomy; Intensive Care; Modified percutaneous dilational tracheostomy
