Swan-Ganz Catheter Insertion

Study Overview
=================
Brief Summary
-----------------
The goal of this prospective randomized controlled study is to investigate the effect of pause of advancement of the Swan-Ganz catheter, which is to check whether the Swan-Ganz catheter arrive exactly at the right ventricle or not, on success rate of final placement and required time in Swan-Ganz catheterization. The question which the investigators are trying to answer is: Continuous advancement of Swan-Ganz catheter without intended pause in the right ventricle to check whether the Swan-Ganz catheter arrive exactly at the right ventricle will decrease the trial number and required time to success final placement of Swan-Ganz catheter?

Detailed Description
-----------------
Many clinicians pause advancement of Swan-Ganz catheter to check whether the Swan-Ganz catheter arrive exactly at the right ventricle or not. The hypothesis of this study is that the intended pause during advancement of Swan-Ganz catheter in the right ventricle induce failure in advancing of it into the pulmonary artery, and that it increase the required time for final placement of it into the pulmonary artery.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: with pause<br>When the practitioner or expert investigator recognize that the tip of Swan-Ganz catheter arrive in the right ventricle, the practitioner pause the advancement for 10 sec. Next, the practitioner re-advance it to the pulmonary artery. | Procedure: with pause<br>* When the practitioner or expert investigator recognize that the tip of Swan-Ganz catheter arrive in the right ventricle, the practitioner pause the advancement for 10 sec. Next, the practitioner re-advance it to the pulmonary artery.<br>|
| Experimental: without pause<br>When the practitioner or expert investigator recognize that the tip of Swan-Ganz catheter arrive in the right ventricle, the practitioner advance it continuously without pause to the pulmonary artery. | Procedure: without pause<br>* When the practitioner or expert investigator recognize that the tip of Swan-Ganz catheter arrive in the right ventricle, the practitioner advance it continuously without pause to the pulmonary artery.<br>|
