Elevation in vas- cular resistance reflects damage to that circulation such as noted in pulmonary vascular obstructive disease due to long standing excessive pulmonary blood flow leading to pulmonary hypertension buy 25 mg indocin visa. Measurement of vascular resistance is important in determining the health of the vascular resistance and whether the blood pressure would return to normal if shunt is eliminated purchase 25 mg indocin amex. Systemic and pulmonary vascular resistance can be calculated using data obtained through cardiac catheterization. Angiography Injection of radioopaque contrast in cardiac chambers and vascular structures while recording radiographic movie clip (30–60 frames/sec) allow clear visualization of cardiac anatomy and defects. Angiography may be performed to demonstrate cardiac anatomy that is not possible to see by less invasive imaging devices or performed in preparation for an interventional procedure. Contrast material filling a cardiovascular structure may show: • Anatomical details of structure. Complications of Cardiac Catheterization Vascular Vascular injury is more likely in small children, when using large sheaths or cath- eters, when patient is using anticoagulants, after interventional procedures, and in arterial access sites. Significant hematomas may occur and if large, may be painful and result in hemodynamic compromise. This is suspected when there is severe back pain, unexplained drop in hematocrit or hemodynamic compromise. Vascular injury as a result of cardiac catheterization includes: • Arterial occlusion: Patency of arteries should always be carefully monitored after cardiac catheterization. Signs of limb ischemia such as pallor, coldness, paresthesia, and decrease or absent peripheral pulses and delayed capillary refill should be monitored and if present treated promptly. Management includes prolonged compression or thrombin injection in selected patients. Arrhythmias: • Atrial and ventricular premature beats are usually caused by catheter manipulation but are insignificant and transient. If it persists, over- drive pacing or electrical cardioversion is performed for termination. It occurs mainly in sick infants and responds to medical or electrical cardioversion. Most common sites of perforations are: atrial appendage and right ventricular outflow tract in small infants. Hemopericardium should be suspected if the patient developed hypoten- sion, enlarged cardiac silhouette, and decreased movement of the silhouette nor- mally generated by contractility. Hypoventilation and Apnea Depressed breathing may result from sedation used to perform cardiac catheteriza- tion. High-risk patients for respiratory depression include: Down syndrome patients, airway abnormality, borderline cardiac function, patients with gastroe- sophageal reflux, increased pulmonary vascular resistance, and the use of prosta- glandin infusion. It is customary in many centers to have experienced anesthesiologists to be supervising anesthesia/sedation, airway patency, and effec- tive respiration during cardiac catheterization, particularly if patients or procedure are deemed high risk. Embolism This may be systemic or pulmonary and include: • Air embolism: this can be prevented by using appropriate size sheath and fre- quent catheter flushing. Allergy It may be precipitated by local anesthetics, iodinated contrast agents, or latex expo- sure. Treatment includes: Diphenhydramine, H2 blockers, fluid resuscitation, and epinephrine. Complications Related to Intervention This includes balloon or device damages to nearby cardiac structures, heart perfora- tions and embolization.

Top on the list of offenders is ragweed - which affects as many as 75 percent of all hay fever sufferers. Common culprits are timothy grass, Bermuda grass, sweet vernal, red top and some blue grasses. The oak tree, which is prevalent throughout the United States, produces large quantities of pollen and is a major cause of allergies. The five most common allergens, according to the ACAAI are: Trees began pollinating in early February and will continue through June, overlapping with our grass season in May and June.” Melting snow has revealed an abundance of outdoor mold growth and the use of indoor humidifiers has contributed to increased indoor mold counts. Heavy precipitation in many areas of the U.S. is associated with a greater release of seasonal pollens according to Clifford W. Bassett, M.D., a fellow of the ACAAI and a clinical assistant professor of medicine at the Long Island College Hospital in Brooklyn, N.Y. The tree pollen season is expected to last through early May.” The primary tree pollen, Oak, began appearing mid-March, and within a week, extremely high pollen counts were recorded. - And finally, consider "allergy vaccination," also known as "allergy immunotherapy," or "allergy shots." Your allergist would test you for specific allergies and then customize a specific treatment regimen for your treatment. - Read labels when using over-the-counter allergy medications, as some may be harmful if used for extended periods of time. The salt water wash moistens nasal mucous membranes and soothes a dry nose. A rainy day is the best remedy to overcome a high pollen dilemma. Humidity and rain, on the other hand, prevent the pollen traffic. In the last few weeks, I have had several patients who have showed up complaining of allergy and upper respiratory symptoms. Seasonal variations may be pleasant to some but a nuisance to allergy sufferers. The American Academy of Allergy, Asthma, and Immunology notes that if you have a pet allergy, you might consider immunotherapy — allergy shots or tablets — that can potentially desensitize you to the allergen and provide lasting relief. To treat allergy symptoms, Jones cautions against older over-the-counter (OTC) medicines, which, he says, can do more harm than good. Treatment Options for Winter Allergy Symptoms. Both share symptoms, such as sneezing, runny nose, and congestion. Clean, dust, and vacuum regularly, using a vacuum with a high-efficiency particulate air (HEPA) filter. It may not be possible to get rid of winter allergies entirely, but you can reduce exposure to allergens, at least in your own surroundings. Indoor Mold We all breathe in mold spores, but for those with an allergy, exposure can trigger sneezing, congestion, and itchiness.
