Vasoconstriction

When Ohil woke up in a crowded hospital room, he wondered where he was. He remembered nothing about how he got there, or who the people around him were. Then he remembered as he drifted off to sleep. He he happily skied down a mountainside when part of one of his skis broke off. He looked down to see what happened and part of the ski was decimated. He went tumbling down the mountain, only to hit a snow covered boulder. He flew into the air in a pandemonium of limbs and skiing equipment when he…

Over the last decade, monumental advances in the medical field have taken place, resulting in prompt recognition and management of many diseases. Despite this, meningococcal disease remains one of the leading causes of death in children and young people worldwide (Dowson, 2014). With its rapid onset and serious nature, meningococcal septicaemia affects up to 0.95% of the western world’s population each year making it essential for health professionals to understand the pathophysiology,…

decrease of its self. Issues that cause an increased PVR can include vasoconstriction drugs, hypercapnia, hypoxemia, atelectasis, and acidemia. Issues that cause a decreased PVR can include vasodilation drugs, hypocapnia, alkalemia, and any form of strenuous exercise (Schnur, 2017). PVR can be treated by treating the cause of what is either increasing or decreasing the PVR. This can include giving vasodilation or vasoconstriction medications depending upon an increased or decreased PVR. For an…

Submit your Case Study in the Drop Box as: Case Study – One Mrs. X comes into the urgent care stating that she does not feel well. Patient states that she burned her forearm two to three days prior when cooking. The patient states that initially the area on her forearm was just “red” with a few small pin head sized blisters. The patient states that she did not put anything on the blisters, as she thought they would diminish within the next day or two. Now the patient presents with a fever.…

to transform from thick-walled muscular vessels to saclike flaccid vessels. Placental hypo-perfusion, caused by the incomplete invasion leads to the release of systemic vasoactive compounds that results in an exaggerated inflammatory response, vasoconstriction, capillary leak, hypercoagulability, platelet dysfunction and endothelial damage (Lim, 2016), all which directly correlates to the severity of maternal hypertension. Another possible cause of preeclampsia is due to an imbalance between…

management is crucial. Effective medications include over the counter analgesics, ketorolac, opioids and hydroxyurea. Application of heat is also beneficial during a crisis, but patients should avoid extreme temperatures due to the potential for vasoconstriction. Patients should be taught proper nutrition, the benefits of adequate hydration, signs and symptoms of infection, and when to obtain medical care. Coping mechanisms should be discussed with patients to assist them in dealing with their…

Dexmedetomidine versus Granisetron for the management of post spinal shivering Abstract Background: Shivering is one of the most stressful complications for patient and surgeon during spinal anesthesia. In this prospective, randomized, double blinded study we compared the efficacy of Dexmedetomidine versus Granisetron for control of post spinal shivering. Methods: study was conducted on 120 patients, ASA I-III, of either sex, aged 18–60 years, scheduled for elective lower abdominal and lower…

The pathophysiology of hypertension is unclear. Some people develop hypertension from an underlying renal or adrenal disease called secondary hypertension, but this is only a small percent. Most people have no single identifiable cause labeling them with a diagnosis of essential (also called primary) hypertension. There are many physiological mechanisms involved in maintaining a normal blood pressure, and the upset of any of these mechanisms may play a role in the development of essential…

hypertension. Consequently, this causes pulmonary edema due to an increased hyperstatic pressure. Globally, she has systemic hypertension a result of vascular spasms and increased heart rate. Symptomatically she feels hot, sweaty, and anxious due to vasoconstriction (increasing heat retention) stimulation of sweat glands, and increased norepinephrine. The cardiovascular system is dynamic and always changing to regulate blood flow to essential organs. Hypertension elevates the blood pressure…

known as adrenalin in the form of epinephrine from the postganglionic axons into the blood stream. The epinephrine is distributed into the circulatory system where it is distributed throughout the body. The epinephrine will travel to different places of the body and have different responses where ever it goes. Also epinephrine does not go into the cells of the body it only binds to the surface of cells by attaching to protein of cells. When it reaches the liver it binds to proteins and then…
