Abstract: Objection To compared the effect between simulaion training and traditional training on central venous cathertrization(CVC). Methods Forty emergency residents came from a teaching hospital were selected during May 2016 to May 2017, and they were randomly assigned into two groups:simulation group（SG）and traditional group（TG）. After the training they must completed one CVC and filled in a questionaire. The success rate、puncture time、trail time and complication rate between the two groups were compared. Results There were 18 students on tradional group(TG) and 19 students on simulation group(SG) who completed the whole procedure(complete the procedure independently and filled in the questionaire). The success rate of SG and TG were 73.7% and 33.3% respectively(P<0.05).the lengthen of procedure was （21.3±4）min on SG and （31.3±5.9）min on TG, The trail times were （2.1±1 ）on SG and （4.5±1）on TG, the complication rate was 16%±37% on SG and 38%±50% on TG, compared with TG, the lengthen of procedure on SG was significantly shortened(p<0.05),the trail times on SG were significantly reduced(p<0.05) and the complication rate was significantly decreased(P<0.05). Conclusions Compared with traditional training , the simulation training significantly improved the success rate of CVC,shortened the lengthen of procedure ,decreased the trail times and complication rate. It deserved teaching hospitals to popularizeing on standardized training for resident physicians.
