简要总结
The objective is to determine the incidence of thrombosis on central venous catheters in patients hospitalized in a surgical critical care unit, in the immediate postoperative period of urological or digestive carcinological surgery, and receiving parenteral nutrition.
详细描述
The post operative period, wich is a critically ill condition, and history of cancer are related to a high risk of venous thrombosis. Catheter is one of the most common complication of parenteral nutrition and is also related to thrombosis.
The combination of theses conditions increases the risk of venous catheter thrombosis. , Since, there is no data evaluating this risk nowadays, the objective of this study is to determine the incidence of thrombosis on central venous catheters in patients hospitalized in a surgical critical care unit, in the immediate postoperative period of urological or digestive carcinological surgery, and receiving parenteral nutrition.

结局指标
主要结局
Presence or no of a catheter related thrombosis
时间窗: 1 day (day of the catheter removal)
Patients will undergo an examination by a specialist in vascular medicine just before removal of the catheter.This specialist also is specialist in vascular doppler ultrasonography. The specialist would search symptoms and signs of deep vein thrombosis : local pain, swelling, redness, warmth. Clinical examinated would be completed by doppler ultrasound : thrombus is detected during a compression test, while cruor is evaluated in B-mode (gray-scale) imaging. This method is very sensitive with regard to detection of the thrombus.
次要结局
- clinical factors associated with the presence of catheter related thrombosis(post operative period, during the intensive care unit stay)
