emergency hipertensive

Rocío Alcántara-Hernández, Aurelio Hernández-Méndez
Adrenaline and noradrenaline bind to membrane receptors of the superfamily of G protein-coupled receptors (GPCR) in target cells, where they modulate physiological responses such as metabolism, vasoconstriction, vasodilation and proliferation. Alteration in their function is associated with conditions such as hypertension, benign prostatic hyperplasia and cardiac hypertrophy. In response to adrenaline, receptors form signaling complexes, which enables adrenergic action to be specific, rapid and efficient. These signaling complexes or signalosomes are composed of kinases, phosphatases, and adapter and scaffold proteins, which together modulate the receptor function...

BACKGROUND: Pneumoperitoneum is defined as the existence of extraluminal air in the abdominal cavity. In 80-90% of cases is due to perforation of a hollow organ. However, in 10-15% of cases, it is nonsurgical pneumoperitoneum. OBJECTIVE: The case of a patient undergoing mechanical ventilation, developing abdominal compartment syndrome tension pneumoperitoneum is reported. CLINICAL CASE: Female, 75 years old asking for advise due to flu of long term duration...

Pediatric Global Case ReportsSESSION TYPE: Global Case ReportPRESENTED ON: Tuesday, October 28, 2014 at 01:30 PM - 02:30 PMINTRODUCTION: Spontaneous pneumomediastinum, also known as Hamman's syndrome, is a condition that usually occurs in young patients, with a male-female ratio of 8:1 cases. The main mechanism is the spontaneous rupture of alveoli, which may occur by increased intra-alveolar pressure or by decrease in peripheral vascular pressure. The clinical picture may vary according to the amount of air extravasated and can include patients who are asymptomatic as well as cases of significant chest pain, severe dyspnea and even death due to conditions associated with hipertensive pneumothorax...

OBJECTIVE: Compare the therapeutic response of symptomatic, hypertensive patients to symptomatic medication or anti-hypertensive drugs at the Emergency Unit. METHODS: A randomized, blind clinical trial involving 100 (one hundred) patients assisted at the Cardiology Emergency Unit at Oswaldo Cruz University Hospital (HUOC). All patients reported symptoms associated to systolic pressure (SBP) between 180 and 200 mmHg and/or diastolic pressure (DBP) between 110 and 120 mmHg...

The management of severe hypertension in the emergency setting demands a careful evaluation of the different underlying clinical situations, and of the impending risk for the life of the patient or of acute organ damage. Hypertensive emergencies and urgencies have to be identified, and distinguished from chronic severe hypertension, a frequent presentation to the emergency services. A thorough clinical evaluation, and not the magnitude of the blood pressure elevation, should be the basis of the differential diagnosis; this will guide the setting required for treatment (intensive care unit, ward or ambulatory), the drugs of choice, as well as the velocity of blood pressure reduction...
