[A randomized study to manage the peripheral intravenous catheter with saline washing]

The scope of this study is to compare the washing of the CVP using normal saline solution before each closure and every 6 hours, with closing the CVP using an obturator after the suspension of the infused therapy, in function of the maintenance of the perviousness and the appearance of complications. The study population included 83 patients; using the randomised trail technique, 40 patients had been assigned to the group of washing and 43 to the group of the obturator. The results of this study demonstrate that, in order to maintain the perviousness of the CVP and the reduction of the appearance of complications, there is no significant difference between the washing of the CVP with normal saline solution before each closure with a stopper and every 6 hours, and the closure of the CVP with an obturator without washing at the suspension of the infused therapy.
