Decent Essays

Postoperative hypertension may cause serious adverse events with both cardiac and non-cardiac patients.1-3 Postoperative hypertension generally occurs within 30 minutes after surgery has been completed and may last up to two hours. Acute perioperative hypertension occurs in 80% of people undergoing cardiac surgery and 25% of people undergoing non-cardiac surgeries, such as head and neck surgery or renal transplantation. If not treated appropriately, an acute increase in blood pressure may be related to further undesired complications, such as myocardial ischemia, stroke, bleeding, and heart failure. Hypertensive emergencies such as postoperative hypertension are more common in patients with uncontrolled hypertension, diabetes mellitus, or renal disease. The main risk factor …show more content…

Hypertension is presented as an increase in blood pressure. Blood pressure is the product of increased cardiac output and systemic vascular resistance. The risk factors are what attribute to the pathophysiology of postoperative hypertension. Hypercarbia causes an increase in catecholamine concentrations, which increases blood pressure. To decrease the risk of end organ damage and surgery complications associated with hypertension, therapy should be initiated in patients with systolic blood pressure above 180 mmHg or a diastolic blood pressure above 110 mmHg once the risk factors (pain, hypercarbia, and excitement on emergence of anesthesia) of postoperative hypertension have been treated. There are many complications and other underlying conditions may be associated with patients postoperatively and the medications chosen to initiate should be based on each individual patient. The ideal medication to treat postoperative hypertension has a quick onset and a short duration of
