Abstract
One hundred and twenty-three dual lumen silicone rubber central venous catheters were inserted into 101 patients with hematological malignancies undergoing intensive treatment. There was a perioperative complication rate of 13%. Open and closed techniques for inserting the catheter were compared. The operating time needed for introducing the catheter by the closed technique (average, 51 minutes) was significantly shorter (p < 0.001) than the time needed for the open technique (70 minutes), whereas complication rates were equal in both techniques. On average, the catheters functioned for 149 days. Complications leading to removal were observed in 29.3% of patients, most of which were catheter-related infections (20.4%). Thromboembolic complications leading to removal were less frequent (4.1%) and appeared significantly earlier (p . Cent vingt-trois cathéters en caoutchouc siliconé à double lumière ont été mis en place afin de traiter 101 patients ayant une maladie hématologique grave nécessitant une thérapeutique lourde. Le taux de complications péri-opératoires était de 13%. L'étude a comparé 2 techniques d'insertion: avec ou sans abord direct. La durée de l'intervention utilisant la technique sans abord direct (51 minutes en moyenne) était significativement plus courte que celle de la technique avec abord direct (70 minutes) (pppp< 0.001). Estos datos indican que: la inserción del catéter por punción directa de la vena subclavia es un método rápido y seguro, y este tipo de catéter es adecuado para uso a largo plazo, tanto para efectos de la infusión como de muestreo de sangre.
