INTRODUCTION The correlation of central venous pressure (CVP) with inferior vena cava (IVC) sonographic diameter has been reported in several studies. However, few studies have attempted to find the best anatomic location of measurement. Therefore, the purpose of this study was determining the best anatomic location to find precise correlation between CVP and IVC diameter using transesophageal ...
Figure 2: CVP waveform after pulling central venous catheter abnormal large a-c wave complex (Figure 1 – marked with red arrow) and CVP value was in the range of 10-12 mm Hg. Such wave pattern may resemble a cannon “a” wave of CVP.[1,2] Transesophageal echocardiography was done which demonstrated lower end of central venous catheter getting abutted with tricuspid valve early in the systole. Thi...
BACKGROUND Microcirculatory driving pressure is defined as the difference between post-arteriolar and venular pressure. In previous research, an absence of correlation between mean arterial blood pressure (MAP) and microcirculatory perfusion has been observed. However, the microcirculation may be considered as a low pressure compartment with capillary pressure closer to venous than to arterial ...
Background: This study was to evaluate whether stroke volume variation (SVV)-guided fluid management would improve postoperative pain perception, plasma lactate and glucose levels, in-hospital mortality and morbidity, and length of hospital stay, when compared with those guided by central venous pressure (CVP). Methods: Ninety-one patients scheduled for major lumbar spine surgery were randomize...
INTRODUCTION Finding the probable governing pattern of PEEP and CVP changes is an area of interest for in-charge physicians and researchers. Therefore, the present study was designed with the aim of evaluating the relationship between the mentioned pressures. METHODS In this quasi-experimental study, patients under mechanical ventilation were evaluated with the aim of assessing the effect of ...
Under heat stress, a decrease of the central venous pressure (CVP) was regularly observed, raising the question of whether this reaction is a limiting factor for the circulation. In animal experiments it could be shown, however, that despite a lowered CVP, which depended on the elevated body temperatures, a high cardiac output (CO), as well as an elevated stroke volume could be maintained. A lo...
In rodents, the circumvallate papilla (CVP), with its underlying minor salivary gland, the von Ebners' gland (VEG), is located on the dorsal surface of the posterior tongue. Detailed morphological processes to form the proper structure of CVP and VEG have not been properly elucidated. In particular, the specific localization patterns of taste buds in CVP and the branching formation of VEG have ...
The objective was to assess changes in the width of the subarachnoid space (SAS) and amplitude of cerebrovascular pulsation (CVP) during acute elevation of intracranial pressure (ICP) using Near Infrared Transillumination/Back Scattering Sounding (NIR-T/BSS). Changes in the width of the SAS and amplitude of CVP were observed in rabbits during experimental ICP elevation induced by: (1) quick inj...
Blood loss and transfusion requirements are major determinants of morbidity and mortality following liver resection. This study evaluates the association of low central venous pressure [LCVP] with blood loss and blood transfusion during liver resection. Thirty consecutive hepatic resections were studied prospectively concerning CVP, volume of blood loss and volume of blood transfusion and renal...
