Brain hypoxia (BH) can aggravate outcome after severe traumatic brain injury (TBI). Whether BH or reduced brain oxygen (Pbto(2)) is an independent outcome predictor or a marker of disease severity is not fully elucidated. To analyze the relationship between Pbto(2), intracranial pressure (ICP), and cerebral perfusion pressure (CPP) and to ...

Background/Aims Current estimates suggest that high blood pressure is present in 3-5% of children, although the prevalence of hypertension in obese children may be as high as 20%. The American Academy of Pediatrics recommends routine blood pressure measurement in children over the age of 3. However, it is not known ...

: Tactical Combat Casualty Care (TCCC) is a system of prehospital trauma care designed for the combat environment. Needle decompression (ND) is a critical TCCC intervention, because previous data suggest that up to 33% of all preventable deaths on the battlefield result from tension pneumothoraces. There has recently been increased ...

Abstract Objectives. Sympathetic activation has a role in the development of left ventricular hypertrophy (LVH). The presynaptic α(2C)-adrenoceptor inhibits the release of norepinephrine from sympathetic nerve terminals in the heart. A deletion polymorphism in the α(2C)-adrenoceptor (α(2C)Del322-325) generates a hypofunctional α(2C)-adrenoceptor, which may result in chronic adrenergic signalling. This study ...

There is increasing evidence to support the use of anesthetics to affect operative fields during endoscopic sinus surgery and thus the speed, thoroughness, and safety of the surgery itself. Previous research has suggested preoperative beta-blockers improve surgical fields (SFs); our study is novel in showing the impact of a beta-blocker ...

Measured blood pressure is an insensitive and moderately nonspecific guide to the presence of vascular or cardiac diseases likely to progress to cardiovascular morbid events. Since the goal of the diagnosis and treatment of hypertension is to prevent or forestall such morbid events, blood pressure measurements should be supplemented by ...

Hemodynamic treatment of subarachnoid hemorrhage-induced vasospasm is associated with a number of systemic and cerebral risks. However, hypertensive encephalopathy has rarely been reported in the setting of induced hypertension. Recognition of this complication is nonetheless critical because failure to lower blood pressure may lead to worsening of deficits and even ...

Noninvasive (NIBP) and intraarterial (ABP) blood pressure monitoring are used under different circumstances and may yield different values. The authors endeavored to characterize these differences and hypothesized that there could be differences in interventions associated with the use of ABP alone ([ABP]) versus ABP in combination with NIBP ([ABP+NIBP]). Simultaneous ...

Recent studies have suggested that aldosterone has many effects in addition to its ability to cause the kidney to retain sodium. To test the hypothesis that aldosterone can cause hypertension in a manner that does not involve renal sodium retention, we administered eplerenone, a specific aldosterone antagonist, to oligo-anuric chronic ...
