Better Arterial Cannulation Technique With Different Hemodynamics

Not Applicable

Completed

• Conditions: Acute Respiratory Failure; Shock
• Interventions: Procedure: Radial artery cannulation

• Registration Number: NCT02825615
• Lead Sponsor: Sultan Qaboos University

Brief Summary

Purpose Two techniques of radial artery cannulation, ultrasound guided (USG) and conventional method (CM) were compared to find the better technique in general and in different hemodynamic subsets of patients.

Method This is a prospective randomized, single center study of 100 patients. The details of the primary cannulation technique, number of attempts, time taken, failure and cross-over technique were recorded for three different hemodynamic subsets with Systolic blood pressure \<80 mm hg, 80-100 mm hg and \> 100 mm hg.

Arm && Interventions

Group	Intervention	Description
Conventional method (CM)	Radial artery cannulation	Radial artery cannulation has been done using the conventional method. Cannulation failure with this technique were tried with USG technique secondarily.
Ultrasound guided method (USG)	Radial artery cannulation	Radial artery cannulation is done with ultrasound guidance for this group of patients. Cannulation failure with this technique were tried with Conventional technique secondarily.

Primary Outcome Measures

Name	Time	Method
First pass success rate	1 year	First pass success rate depicted the better method of cannulation of radial artery
Final/ultimate success rate of an intervention	1 year	If the primary technique failed then the cannulation was done with the secondary technique and hence the final success rate was calculated for each of the techniques: conventional and ultrasound guided.

Secondary Outcome Measures

Name	Time	Method
Time taken for the respective technique	1 year	Time taken for each technique was calculated from start of needle insertion till the cannula was completely inserted. The time was compared between the two arms
Attempts of cannulation	1 year	Number of attempts made by a technique was recorded and compared
