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.
