BACKGROUND In patients with burns, an early accurate diagnosis of burn depth facilitates optimal treatment. Laser Doppler imaging combined with clinical assessment leads to an accurate estimate of burn depth. However, the actual effects of the introduction of laser Doppler imaging on therapeutic decisions, clinical outcomes, and costs are unknown. METHODS A randomized controlled trial was con...

Bu~~AG, RUBEN D. Validation in awake rats of a tail-cuf method for measuring systolic pressure. J. Appl. Physiol. 34(2) : 279-282. 1973. -To determine why results of recent studies on applicability of the tail-cuff method to awake rats have been conflicting, arterial pressures were measured under various conditions. A Doppler ultrasonic flowmeter was used to detect blood flow changes occurring ...

Purpose To evaluate the retinal microcirculation using a segmental-scanning Doppler optical coherence tomography (DOCT) flowmeter in a patient with Takayasu's arteritis (TA) with aortic valve regurgitation (AR). Observations We measured the retinal blood velocity (V), retinal blood flow (RBF), and retinal blood velocity profiles (RBVP) of the major retinal arterioles using a DOCT flowmeter. T...

The goal of this study was to compare oral mucosal blood flow and duration of anesthetic action after stellate ganglion block (SGB) using lidocaine, with or without epinephrine, and discuss the effect of epinephrine on SGB. Duration of anesthetic action was defined as elapsed time from finish of injection to recovery of common carotid blood flow (CCBF) to within+/-5% of respective control value...

INTRODUCTION Disturbances in microcirculatory homeostasis have been hypothesized to play a key role in the pathophysiology of multiple organ dysfunction syndrome and vasopressor-associated ischemic skin lesions. The effects of a supplementary arginine vasopressin (AVP) infusion on microcirculation in vasodilatory shock and postoperative multiple organ dysfunction syndrome are unknown. METHOD ...

BACKGROUND/AIM Blood flow measures acquired using the scanning laser Doppler flowmeter (SLDF) are known to be highly susceptible to spatial and temporal variations of physiological origin. The purpose of this study was to evaluate a local search strategy intended to overcome these intrinsic variations, thereby improving the detection of blood flow defects resulting from glaucoma. METHODS The ...

OBJECTIVE The patency of a pedicled right gastroepiploic artery (RGEA) graft can be compromised by intraoperative twists, kinks or spasms. Therefore, a systematic flow assessment was made in RGEA grafts and was compared with similar measurements made in other types of bypass conduits. METHODS Intraoperative pulsed Doppler flowmeter measurements obtained in a series of 556 consecutive patients...

Accurate and objective assessment of amputation level in the lower limb plays an important role in patient management. Laser Doppler flowmetry (LDF) is a new and noninvasive technique for skin blood flow measurement and has been used pre-operatively in 25 patients undergoing amputation for vascular disease and in five normal controls. Baseline flux measurements were made at room temperature on ...
