He then walked upstairs to the Radiology Department where a chest film confirmed the position of the catheter Forssman was a surgeon and did not realize the potential diagnostic value of his procedure generic sildalis 120mg without a prescription. He thought that it might be a method of central administration of drugs where peripheral venous access was difficult buy sildalis 120 mg with visa. It was not until 1941 when Richards and Cournand began a series of cardiac catheterizations at Bellevue Hospital in New York City that right heart catheterization became accepted as an important method of studying the circulation discount sildalis 120mg without a prescription. Subsequent developments are listed next: 1947 - Pulmonary artery and pulmonary wedge pressure measurements; Dexter 1947 - Diagnosis of congenital heart disease-valvular stenoses and shunt flows; Bing - Dexter 1950 - Retrograde catheterization of the left ventricle; Zimmerman 1953 - Seldinger technique of percutaneous arterial catheterization 1959 - Transseptal left atrial catheterization; Ross and Cope 1959 - Selective coronary arteriography; Sones 1970 - Balloon tipped flow guided catheter; Swan & Ganz Cardiac Output and Catheterization – Rajesh Dash, M. The fluid filled catheter is then advanced under fluoroscopic control to the right atrium, right ventricle and pulmonary artery for pressure measurements, blood sampling or injections of dye or cold saline to measure cardiac output. Right atrial mean pressure using the midchest in the supine position as a reference point will provide a rough estimate of the intravascular fluid volume if cardiac function is normal, a low pressure 0-2 mm indicating hypovolemia and a high pressure >12 mm indicating hypervolemia. With the advent of the Swan-Ganz catheter -a balloon tipped flow guided catheter that can be inserted percutaneously at the bedside-pulmonary artery catheterization has been greatly simplified and is the most common method of right heart catheterization employed in intensive care units. Inflation of the balloon will obstruct flow in the catheterized branch of the pulmonary artery and the retrograde pressure of the left atrium can be measured (pulmonary wedge or capillary pressure). A second proximal lumen will permit blood sampling or injection of dye or cold saline in the pulmonary artery. When the pulmonary artery balloon is inflated (Swan-Ganz catheter) or an ordinary cardiac catheter is advanced so that it "wedges" in a small pulmonary artery the retrograde pressure reflects left atrial pressure minus about 2 mmHg. In some instances of obliterative pulmonary hypertension or pulmonary venous occlusive disease a true wedge pressure may not be obtained. Systemic (peripheral) blood flow is then established by averaging the Cardiac Output and Catheterization – Rajesh Dash, M. Pulmonary flow is estimated by entering the O2 contents of the pulmonary artery and a peripheral artery into the Fick equation (the minute O2 uptake in the steady state is the same for lungs as for the systemic peripheral circulation; i. Serial sampling of oxygen contents of the proximal vena cavae, right atrium, right ventricle and pulmonary artery will localize the shunt, including atrial and ventricular septal defects and a patent ductus arteriosus. In cases of occlusive diseaseof the iliac or femoral vessels the brachial (or radial) artery may be used. Catheterization of the left ventricle is usually performed via the femoral artery and occasionally via the brachial artery using a percutaneous puncture via a modified Seldinger method (femoral artery) or direct exposure (brachial artery). The catheter is advanced retrograde into the ascending aorta and passed across the aortic valve into the left ventricle. Ventricular pressures can be recorded using either fluid filled catheters or in special studies a catheter tipped pressure manometer (Mylar catheter) may be employed. The latter method gives more precise pressure measurements but is not usually employed in diagnostic studies. Central aortic pressures are recorded by pulling the catheter back across the aortic valve while recording the pressure This method is employed in the diagnosis of aortic stenosis. A major risk of arterial and left heart catheterization is local arterial damage - thrombosis or hemorrhage. Angiographic studies of the heart, coronary arterial bed and other circulations 2.

Beta adrenergic receptor antagonists Physics of Circulation - Michael McConnell, M. Non-linear aspects of the circulation, including turbulent flow, blood viscosity, and trans-capillary flow. The goal of these lectures is to apply several basic laws of physics toward understanding how blood flows and how the properties of the circulation - pressure, flow, velocity, vessel size, resistance, etc. The first step in understanding the physics of the circulation is to apply our intuition about the physics of solids to the physics of a fluid, in this case blood. Normally when we think of force, velocity, or potential and kinetic energy, we think in terms of a discrete, solid object. A fluid is more dynamic - it can change its shape and different parts can move at different velocities. Yet the same basic laws apply, it is simply a matter of expanding our intuition and terminology to describe the physics of fluid flow. While an object has a mass (m) and coefficient of friction (kf), a fluid will be described by its density (p) and viscosity g It is important to see that the laws have not changed, just the environment in which we apply them. As fluids are not discrete objects, it is more convenient to consider the force (F) per surface area (A), which is pressure (P). Consider the situation (fortunate or unfortunate) of 86 medical students piled into a sizable hot tub (like water in a beaker), as shown in the figure below. You would not have much difficulty reporting that there is a force acting on you due to the gravitational force on the mass above you. If we represent this mass by its density (p) and volume (V), we can say: F = mg = (V) g (m = V) Normalizing for the surface area at depth (d), which will be the cross-sectional area of the tub (A), we can derive the pressure (P): 3. While we use the geometry of the tub in the above example to illustrate the relationship of pressure to force, the pressure is actually independent of the geometry of the container. The figure below shows a variety of different geometries, and yet the height of each column is the same and the pressure at depth d is also identical. Pressure depends solely on the distance from the surface (d), as can be seen from the formula. The independence from specific geometry makes pressure an ideal variable to describe force on fluids. Just as force can cause the motion of an object, pressure can generate the flow of a fluid. Flow (Q) is defined as the amount, or volume (V), of fluid passing a point per unit time (t): Physics of Circulation - Michael McConnell, M. Velocity (v), on the other hand, is the speed with which individual elements of the fluid pass that point: v = x/t (units - m/sec) 3. Flow (Q) through a cylindrical tube is equal to the average velocity (v) of the fluid multiplied by the cross-sectional area (A) of the tube: Q = Av 4. For a closed-loop system, like the circulation, fluid cannot enter nor leave, so there is conservation of mass or a conservation of volume (assuming density is constant). Thus, the amount of blood that leaves the heart through the aorta must equal the amount of blood that flows through the capillary bed, which must equal the amount of blood that returns to the heart via the venae cavae (ignoring coronary and bronchial circulation). Otherwise there would be a build- up or loss of blood somewhere in the circulation. For example, the aorta has a high velocity and small area, whereas the capillary bed has a low velocity and large area. An important characteristic of the circulation is the resistance to blood flow through the vasculature.

The idea for such a book grew out from some of the entries in our sister book Clinical Pharmacy Pocket Companion, which, as well as covering many clinical topics such as electrolyte disturbances and perioperative management of medicines, also deals with a number of medicines requiring therapeutic monitoring. It became apparent that the benefits of such an approach could be rolled out to a greater number of medicines. This requires organisations to risk assess individual parenteral drugs and put procedures in place to allow them to be handled more safely. The Injectable Drugs Guide is a handbook supporting the risk assessment process (each drug has a risk rating). It also provides a holistic approach to injectable medicines to meet the needs of the many disciplines involved in the clinical use of injectables and also those providing advice about injectable drug use. There are a number of appendices giving further guidance on specific aspects of injectable therapy and additional clinical information (the full list of these is found on the Contents page). This is because there are tight controls around the use of these agents in clinical practice. Their handling in clinical settings is highly protocol driven and locality specific; use by inexperienced individuals is inappropriate. Alistair Gray Jane Wright Vince Goodey Lynn Bruce November 2010 H ow to use the Injectable rugs uide m onographs Each monograph is presented in a format that sequences the information as needed by healthcare professionals from contemplation of treatment, through preparation and administration, to the monitoring that may be required during and after therapy. Monographs are generally presented in the following order: Drug name and form(s) of the preparation(s) Background information about each medicine including, * Type of drug * What it is used to treat (licensed and unlicensed indications and routes) * Additional miscellany of interest to the user * If appropriate, how doses of the drug are usually expressed Pre-treatment checks including, * Contraindications and cautions to be considered prior to use * Any measures and/or tests that should be undertaken before commencing therapy. In some cases these tests are mandatory; in others they are dependent on the circum- stances in which the drug is being used. Dose including indication-specific information and any adjustments required in renal or hepatic impairment. Unless otherwise stated, doses are for adults (child and neonatal doses have not been included). Routes of administration * A series of headings outline the route(s) by which a particular drug may be given; the specifics of preparation and administration are provided for each route. In some cases the individual heading indicates the circumstances in which a particular route is appropriate. However, some monographs use the phrase ‘dilute in a suitable volume of compatible infusion fluid’. In this case the prescriber should choose a volume and fluid that is appropriate to the patient’s needs and clinical condition (compatibility data are given further down the monograph in the Technical Information table). How to use the Injectable Drugs Guide monographs | xi Technical information includes details of: * Incompatibilities with fluids, other drugs by Y-site administration and also some- times with materials * Compatibilities with infusion fluids and also drugs where co-administration and concentrations are likely to be used in practice. Drugs for which compatibility is concentration-specific are not included in this list. This is not provided so that infusions can be prepared significantly prior to use in a clinical area, but rather to indicate how long a preparation is stable if it is not possible to administer it immediately. Monitoring includes the measures required to ensure the medicine is used safely throughout therapy, the clinical outcome and other parameters that need consider- ation, e. The frequency of monitoring of each parameter is stated and the rationale for monitoring. Additional information includes Common and serious undesirable effects including: * Immediate adverse reactions or those that may occur shortly after administration * Injection- or infusion-related adverse events, either due to rapid administration or those which are injection-site related * Other adverse reactions Pharmacokinetics in the main provides an indication of the elimination half-life of the drug, which can be useful in determining duration of effect. Some monographs provide information on other pharmacokinetic or pharmacodynamic parameters where these might be helpful. Significant interactions drugs are grouped together under subheadings to give an indication of likely effect of the interaction. These lists are not comprehensive and more detailed sources such as Stockley’s Drug Interactions2 should be used if required. Action in case of overdose gives guidance on managing therapeutic overdose of the drug and in most cases lists general supportive measures required. For the management of significant overdose an on-line source such as Toxbase3 should always be consulted. Counselling points are intended to provide a prompt for healthcare professionals as they speak to patients about their therapy. Any other reference source used is stated in the normal way using the Vancouver system of referencing.
