USG guided central venous cannulation in ICU : a comparision with conventional approach
Critical Ultrasound Journal volume 7, Article number: A1 (2015)
The introduction of portable ultrasonography machines into clinical practice has found widespread usage in the ICUs. They are handy and serve as point of care resource.
Among the common usage in ICU include
Central venous cannulation
Assessment of the cause of abdominal distension
Identification of pericardial tamponade
Valvular pathology & LV function
This saves time and is also safer as it avoids shifting of critically ill patients to other departments.
We performed a study to compare USG & conventional techniques of CVC.
Material and methods
We performed the study in 60 patients over a period of 3 months. A portable ultrasound machine (Sonosite Micromax) was used with a probe of 7.5 MHz frequency. Cannulation was done using real time imaging. In the conventional method cannulation was done using the landmark approach. The parameters studied included
Time from completion of draping to successful insertion of needle.
Number of attempts required.
Incidence of complications.
We found that USG approach took lesser time, required lesser attempts and had lower incidence of complications.
USG guided CVC is easier, quicker & safer than landmark approach.
