Central venous catheterization for acute trauma resuscitation: Tip position analysis using routine emergency computed tomography

Le résumé fourni par la source

PURPOSE: Central venous catheter insertion for acute trauma resuscitation may be associated with mechanical complications, but studies on the exact central venous catheter tip positions are not available. The goal of the study was to analyze central venous catheter tip positions using routine emergency computed tomography. METHODS: Consecutive acute multiple trauma patients requiring large-bore thoracocervical central venous catheters in the resuscitation room of a university hospital were enrolled retrospectively from 2010 to 2015. Patients who received a routine emergency chest computed tomography were analyzed regarding central venous catheter tip position. The central venous catheter tip position was defined as correct if the catheter tip was placed less than 1 cm inside the right atrium relative to the cavoatrial junction, and the simultaneous angle of the central venous catheter tip compared with the lateral border of the superior vena cava was below 40°. RESULTS: During the 6-year study period, 97 patients were analyzed for the central venous catheter tip position in computed tomography. Malpositions were observed in 29 patients (29.9%). Patients with malpositioned central venous catheters presented with a higher rate of shock (systolic blood pressure <90 mmHg) at admission (58.6% vs 33.8%, p = 0.023) and a higher mean injury severity score (38.5 ± 15.7 vs 31.6 ± 11.8, p = 0.041) compared with patients with correctly positioned central venous catheter tips. Logistic regression revealed injury severity score as a significant predictor for central venous catheter malposition (odds ratio = 1.039, 95% confidence interval = 1.005-1.074, p = 0.024). CONCLUSION: Multiple trauma patients who underwent emergency central venous catheter placement by experienced anesthetists presented with considerable tip malposition in computed tomography, which was significantly associated with a higher injury severity.
