INTRODUCTION

The placement of central venous catheters (CVC) is a frequent procedure in intensive care. It is not devoid of complications, the diagnosis of which relied for a long time on the chest X-ray. Currently, ultrasound appears to be an interesting alternative.

AIM: To report the impact of the use of ultrasound on the time to exclusion of mechanical complications after CVC placement.

METHODS

This is a prospective, multicenter, comparative, double-blind study. Were included the patients in whom the placement of a CVC was decided. After placement, a chest X-ray was ordered and an ultrasound was performed to look for signs of misplacement and pneumothorax. The two examinations were interpreted by two different doctors. The primary endpoint between the ultrasound group and the RTX group was the time "T1" represented by the time required to exclude complications.

RESULTS

30 patients were included in our study. The mean ultrasound T1time was significantly lower than the mean radiological T1time (p=0.000). Only one case of pneumothorax was observed. It was first detected by ultrasound. For the 29 other patients, exclusion of pneumothorax was confirmed by ultrasound and chest X-ray. No misplacement type complications detected. This was confirmed by ultrasound and radiological exclusions.

CONCLUSION

Ultrasound is a faster tool than RTX in excluding mechanical complications after CVC placement. It guarantees a non-irradiating examination as efficient as chest X-ray for intensive care patients.
