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
Radial Artery cannulation using conventional palpation vs USG guided Dynamic needle tip positioning (DNTP) method.
To evaluate the value of US-guided Stellate ganglion block for improving radial arterial blood flow and peripheral perfusion in Septic shock patients on vasopressor support with an indwelling radial arterial cannula, which can result in reduced incidence premature failure of the catheter (due to vasospasm or thrombosis) and incidence of ischemic complications in the cannulated arm.
Invasive blood pressure monitoring is achieved by cannulating an artery and transducing the pressure. During arterial cannulation the artery can be located by palpation, but use of ultrasound has increased the success rate of cannulation. A new ultrasound technique for vascular cannulation (dynamic needle tip positioning) has been described. Investigators aim to compare this technique to the palpation technique for arterial cannulation. Investigators hypothesize that the use of this novel ultrasound technique will result in a higher first attempt success rate and overall success compared to palpation. Investigators plan to enroll 310 patients in this study. The participants in the study will have been deemed by the attending anesthesiologist to require a radial arterial line for the operation and thus the research protocol will not involve a deviation from the standard of care.
