Detailed Description
The practice of placing vascular catheters is used many times every day at almost every hospital. It is a safe procedure which generally does not imply problems. Though the procedural optimum aren't reached. The procedure still fails some times and induce complications. When the catheter is placed using the traditional method the pulse is palpated by the operator's fingers. This is only to be done near the hand wrist. In this position the catheter steadiness is fragile but because the pulse can't be sensed more proximal the operator is forced to choose this position. This it though a problem that can be solved by non invasive visualization technology. Ultrasound-guidance for central vascular access is already well-established. However, in recent years ultrasound-guidance for peripheral vascular access has gained popularity too. The evidence of multiple studies demonstrates increased success rate and reduced complication rate with ultrasound compared to blind landmark technique for vascular catheter placement.
In recent years there have been both procedural technique and technology improvements in the field of ultrasound. This has led to the improvement of procedural catheterisation techniques that now can be done by novices with higher attempt success rate than traditional method. One technique that is gaining success is the short-axis-out-of-plane technique (SAX-OOP) with dynamic-needle-tip-tracking (DNTT).Using the ultrasound machine the needle can be placed in a more proximal direction on the forearm and the investigators believe that by the help of the exposed procedure on the monitor many complications can be reduced.
Hypothesis; Firstly the investigators hypothesize that the pain induced by the conventional method inclusive preoperational lidocaine injection will be the same or more intense than using DNTT without local anesthesia. Secondly the investigators hypothesize that the use of DNTT for the placement of the arterial catheter will decrease the time spend, amount of complications (hematoma), the number of pricks, the number of utilized catheters compared to the traditional palpation method. Thirdly the investigators claim that the best anatomical place to put the catheter isn't always corresponding with the spot chosen by palpation, which increase the number of failures.
