[A study on feasibility of emergency bedside ultrasound-guided central venous catheterization].

ABSTRACT

OBJECTIVE: To evaluate the feasibility and clinical significance of emergency bedside ultrasound-guided central venous catheterization performed by emergency department doctors. METHODS: The clinical data of 216 patients, who underwent central venous catheterization in the Department of Emergency of Shengjing Hospital of China Medical University from January 2009 to June 2014 were retrospectively analyzed. All the patients received femoral vein puncture or internal jugular vein catheterization. The patients were divided into three groups according to the method of catheterization 72 patients received emergency ultrasound-guided central venous catheterization by emergency doctors independently were assigned as A group, 72 patients underwent catheterization by emergency doctors after being demarcated by ultrasound doctors served as B group, and 72 patients who underwent catheterization method guided by traditional landmark served as C group. Success rate, time spent for catheterization, number of attempts for intubation, and incidence of complications were compared among three groups. RESULTS: As compared with that of groups B and C, a higher success rate [98.61% (71/72) vs. 83.33% (60/72), 73.61% (53/72), both P < 0.01] was found in group A, also with a shorter successful time for insertion of the catheter (minutes 5.5 ± 2.5 vs. 9.6 ± 3.7, 16.6 ± 7.2, both P < 0.05), less frequency of the catheter insertion (times 1.0 ± 0.0 vs. 1.8 ± 0.7, 2.7 ± 2.6, both P < 0.05), and lower incidence of changing puncture site due to insert failure [1.4% (1/72) vs. 8.3% (6/72), 20.8% (15/72), both P < 0.05], lower incidence of mechanical and infective complication [15.3% (11/72) vs. 41.7% (30/72), 59.7% (43/72), both P < 0.05], and also lower catheterization related infection risk [13.9% (10/72) vs. 15.3% (11/72), 12.5% (9/72), both P > 0.05]. CONCLUSION: Emergency bedside ultrasound-guided catheterization resulted in higher success rate and less related complication, therefore it can be recommended for widely application in emergency department treatment.
