Ultrasound Guided Peripheral Venous Cannulation in Patient Undergoing Elective Surgery Under General Anesthesia.

Study Overview
=================
Brief Summary
-----------------
This study evaluates two different techniques for peripheral venous cannulation in operating theatre. Ultrasound guided insertion of peripheral cannula in comparison with conventional approach without any ultrasound guidance.

Detailed Description
-----------------
Peripheral venous catheter placement is one of the key tasks of an anesthesiologist, which needs to be completed before surgery in general anesthesia. The reported success rate of peripheral venous cannulation, when performed in a conventional manner, without any special technical tools which facilitate finding the peripheral vein, is only 51% during the first trial. However, up to 7% of patients require more than three cannulation trials. Ultrasound guidance of peripheral venous catheter insertion may increase success rate and shorten time to securing peripheral cannula. However, this approach has not been verified in the setting of operating theatre so far. This project aims to set the role of ultrasound guided venous cannulation in operating theatre.

Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Ultrasound guided cannulation<br>Ultrasound guided insertion of peripheral vein cannula. | Procedure: Peripheral vein cannulation<br>* The target vein is directly identified by ultrasound, the procedure of peripheral venous catheter insertion is performed conventionally, without ultrasound guidance<br>|
| Active Comparator: Cannulation without ultrasound<br>Catheter insertion by conventional approach, without ultrasound guidance | Procedure: Cannulation without ultrasound<br>* Cannulation is done the conventional way without any ultrasound use.<br>|
