Randomized Controlled TrialAngiotensin II receptor blockers following intravenous nicardipine administration to lower blood pressure in patients with hypertensive intracerebral hemorrhage: a prospective randomized study.
In patients with hypertensive intracerebral hemorrhage (HICH), intravenous nicardipine is primarily used to lower blood pressure (BP). However, there are few studies investigating the role of oral antihypertensives administered after intravenous nicardipine to prevent BP from rising. Angiotensin II receptor blockers (ARBs) may be beneficial in HICH patients not only as antihypertensives but also by lowering plasma catecholamine levels. A prospective randomized study was conducted between January 2015 and March 2016 to comparatively evaluate the efficacy of two ARBs (azilsartan vs. candesartan) following intravenous nicardipine administration on BP reduction. ⋯ Administration of ARBs following intravenous nicardipine effectively prevented BP from rising in HICH patients. However, whether BP should be strictly managed after 24 h of symptom onset should be addressed in future studies focusing not only on neurologic but also on cardiovascular and renal functions of HICH patients.

The acute effect of high-dose intravenous vitamin C and other nutrients on blood pressure: a cohort study.
Regular intake of vitamin C/ascorbate reduces blood pressure (BP) in hypertensives. High-dose intravenous vitamin C (IVC) achieves higher plasma levels; however, there is a paucity of research on acute BP effects. Our study is the first to investigate the effect of high-dose IVC, with or without concomitant i.v. nutrients, on BP during i.v. ⋯ Our study suggests an acute BP-reducing effect of high-dose IVC, particularly with dosages above 30 g, and in patients with prehypertension and normal BMI. Furthermore, our study indicated a marked and clinically relevant hypertensive effect of IVB12, suggesting routine BP monitoring during i.v. therapy in clinical practice.

Observational StudyDorsalis pedis arterial pressure is lower than noninvasive arm blood pressure in normotensive patients under sevoflurane anesthesia.
It is widely known that blood pressure (BP) in the lower extremity is higher than in the upper extremity. However, whether this phenomenon remains the same during general anesthesia is still unclear. This study aims to investigate the difference between invasive dorsalis pedis artery (DPA) pressure and the most commonly used noninvasive arm pressure during sevoflurane anesthesia. ⋯ DPA pressure tends to be lower than arm pressure under sevoflurane anesthesia, especially the mean blood pressure and the diastolic blood pressure. Hence, noninvasive arm BP monitoring is recommend to be retained when invasive BP is measured at the DPA, so as to allow clinicians to comprehensively evaluate the BP condition of the patients and make appropriate therapeutic decisions.

Prediction of hyperdynamic circulation by arterial diastolic reflected waveform analysis in patients undergoing liver transplantation.
In cirrhotic patients with hyperdynamic circulation characterized by a decrease in systemic vascular resistance (SVR) and an increase in cardiac output, cardiac and vascular properties are expressed in peripheral arterial pressure waveforms. We attempted to assess whether the variables derived from the radial artery waveform can predict hyperdynamic circulation in liver transplant recipients. ⋯ Diastolic reflected waveform characteristics can be used to predict high CI and low SVR in liver transplant recipients. This study suggests that these minimally invasive indicators may also be valuable when pulmonary artery catheterization is not available in patients with a hyperdynamic condition.

Elevated blood pressure in the emergency department: lack of adherence to clinical practice guidelines.
To determine emergency physician's adherence to American College of Emergency Physicians policy recommendations in the assessment of patients with asymptomatic elevated blood pressure (BP) in the emergency department (ED). ⋯ A vast majority of ED patients with persistently elevated BP did not receive BP counseling and referral for further evaluation of elevated BP, suggesting lack of adherence to American College of Emergency Physicians policy recommendations in the assessment of ED patients with asymptomatic elevated BP.
