BACKGROUND Although the central venous pressure (CVP) is often used as a guide to volume status in major surgery and intensive care, fluid therapy should be guided by the response of the stroke volume (SV) to a fluid bolus. The present study evaluates whether the central venous pressure (CVP) can serve as an adjunct to decisions of whether or not fluid should be infused. METHODS Stroke volume...

BACKGROUND Changes in central venous pressure (CVP) rather than absolute values may be used to guide fluid therapy in critically ill patients undergoing mechanical ventilation. We conducted a study comparing the changes in the CVP produced by an increase in PEEP and stroke volume variation (SVV) as indicators of fluid responsiveness. Fluid responsiveness was assessed by the changes in cardiac o...

Objective Chronic visceral pain (CVP) syndromes are persistently painful disorders with a remarkable lack of effective treatment options. This study aimed at evaluating the effects of different neuromodulation techniques in patients with CVP on cortical activity, through electreocephalography (EEG) and on pain perception, through clinical tests. Design A pilot crossover randomized controlled ...

Background Despite constant fluctuations in cardiac preload caused by the effects of respiration and changes in posture on venous return to the heart, arterial blood pressure remains remarkably constant. The effects of instantaneous lung volume (ILV) and variations of central venous pressure (CVP) on blood pressure (BP) were studied by use of frequency domain techniques to quantify the contribu...

BACKGROUND Radiotherapy is commonly used as a first-line treatment for localized ocular adnexal extranodal marginal zone B-cell lymphoma (EMZBL), despite its ophthalmologic complications. This study was undertaken to analyze the efficacy of first-line chemotherapy in treating EMZBL. Chemotherapy was followed by radiotherapy only in recurrent cases. PATIENTS AND METHODS Twenty-one patients wit...

PURPOSE To date, the risk factors for central venous port-related bloodstream infection (CVPBSI) in solid cancer patients have not been fully elucidated. We conducted this study in order to determine the risk factors for CVP-BSI in patients with solid cancer. MATERIALS AND METHODS A total of 1,642 patients with solid cancer received an implantable central venous port for delivery of chemother...

One hundred mice were randomly divided into five groups. The mice in one group were injected with physiological saline as the normal control group. The mice in the other four groups were injected with physiological saline, sulfated Chuanminshen violaceum polysaccharides (SCVP), Chuanminshen violaceum polysaccharide (CVP) and astragalus polysaccharide (AP) once daily for 7 d and then with cyclop...

OBJECTIVE To evaluate the correlation between central venous pressure (CVP) and inferior vena cava (IVC) diameters measured by ultrasonography (Ultrasound) in critically ill patients. METHODS Intubated critically ill patients were enrolled. The CVP values were measured using a U-tube manometer and were compared to the IVC diameters and collapsibility index, which were measured by bedside Ultr...

PURPOSE R-CHOP (rituximab with cyclophosphamide, doxorubicin, vincristine and prednisone) and R-CVP (rituximab with cyclophosphamide, vincristine and prednisone) have both been used successfully in the treatment of patients with symptomatic follicular lymphoma (FL). No study has compared the efficacy of the two treatment modalities and attempted to evaluate the role of anthracyclines in the man...

OBJECTIVE To determine the correlation between blood gas parameters and central venous pressure (CVP) in patients suffering from septic shock. METHODS Forty adult patients with diagnosis of septic shock who were admitted to the emergency department (ED) of Shohadaye Tajrish Hospital affiliated with Shahid Beheshti University of Medical Sciences, and met inclusion and exclusion criteria were e...
