Summary

Arterial line placement is often needed in various critical care settings. It is a basic procedure performed for continuous blood pressure (BP) monitoring and rapid access for repeated arterial blood gas samples, as it is considered to be more precise than measurement of BP by other noninvasive devices, especially in the critically ill patients or those on continuous infusions of vasoactive drugs.Arterial line placement is presumed to be a relatively safe procedure, with a rate of major complications that is below 1%. The most common site of cannulation is the radial artery, primarily due to the ease of access owing to the superficial nature of the vessel and the ease with which the site can be maintained. Additional advantages of radial artery cannulation include anatomical reliability and the less complications. However placement of a radial artery catheter can, at times, be difficult because many patients who emergently need a catheter may have a weak arterial pulse due to dehydration or blood loss or may have some form of peripheral vascular disease. Although it is usually a well-tolerated procedure, it is considered more painful than intravenous (i.v.) cannula placement, particularly in case of multiple attempts of cannulation

In this study the investigators will assess the effect of ultrasound guided median nerve block, radial nerve block and local infiltration with lidocaine on feasibility of radial artery cannulation in patients undergoing major surgeries

Objectives

1. To evaluate the effect of ultrasound guided median nerve block, radial nerve block and local infiltration on feasibility of radial artery cannulation
2. To determine the effect of ultrasound guided median nerve block, radial nerve block and local infiltration in reducing discomfort and complicationassociated with radial arterial cannulation .

3\. To evaluate the effect of ultrasound guided median nerve block, radial nerve block and local infiltration in radial artery diameter and blood flow for radial arterial cannulation

Conditions

  • Radial Artery Cannulation

Interventions

PROCEDURE

median nerve block

It will be given by one researcher using 5 ml 0.25% bupivacaine with 1% lidocaine for each nerve block after negative aspiration for blood so as to cover the nerve circumferentially

PROCEDURE

radial nerve block

It will be given by one researcher using 5 ml 0.25% bupivacaine with 1% lidocaine for each nerve block after negative aspiration for blood so as to cover the nerve circumferentially

PROCEDURE

local infiltration

intradermal infiltration followed by a subcutaneous injection with a total of 3 mL of 0.25% bupivacaine with1% lidocaine with a27- G needle
