A malpositioned central venous catheter can cause constant excessive pressure on one particular area of a central vein, thus leading to perforation and hydrothorax. The following is a case report of an iatrogenic hydrothorax caused by a malpositioned central venous catheter. The subtle sign of malposition is a slightly curled catheter tip.

background: central venous catheters (cvcs) have been used widely in clinics. these catheters are also recommended for children and infants receiving chemotherapy and total parenteral nutrition (tpn) and etc. in this paper, we present migrated fractured control line of the heart of a girl. case presentation: a 2.5 year old girl with migrated of the fractured central line into the heart. in the ...

introduction: determining the proper angle for inserting central venous catheter (cv line) is of great importance for decreasing the complications and increasing success rate. the present study was designed to determine the proper angle of needle insertion for internal jugular vein catheterization.  methods: in the present case series study, candidate patients for catheterization of the right i...

No study has been performed on reflexes originating from receptors in the heart that might be involved in the pathological lesions of Chagas' heart disease. Our study was undertaken to analyze the role of cardiopulmonary reflex on cardiovascular control in Chagas' disease. We studied 14 patients with Chagas' disease without heart failure and 12 healthy matched volunteers. Central venous pressur...

Monitoring of hemodynamic and mechanical parameters of the heart are reviewed. Clinical methodologies are discussed along with tools used in a research setting. Specifically, these include: arterial blood pressure, central venous pressure, pulmonary artery pressure, mixed venous oxygen saturation, cardiac output, pressure–volume loops, flow monitoring, and Frank–Starling curves. These parameter...

We present a case of a patient exhibiting isolated elevation of the central venous pressure with minimal hemodynamic deterioration in an immediate postoperative period after Bentall operation requiring re-exploration. Isolated elevation of the central venous pressure usually alerts physicians of a volume overload or right ventricular dysfunction. However, even in the absence of significant hemo...

INTRODUCTION Central venous pressure (CVP) measurement is essential in the management of certain clinical situations, including cardiac failure, volume overload and sepsis. CVP measurement requires catheterization of the central vein which is invasive and may lead to complications. The aim of this study was to evaluate the accuracy of measurement of CVP using a new noninvasive method based on n...

The extent to which heat stress compromises blood pressure control is variable among individuals, with some individuals becoming very intolerant to a hypotensive challenge, such as lower body negative pressure (LBNP) while heat stressed, while others are relatively tolerant. Heat stress itself reduces indexes of ventricular filling pressure, including central venous pressure, which may be refle...

We tested the hypothesis that markers of coagulation activation are greater during lower body negative pressure (LBNP) than those obtained during blood loss (BL). We assessed coagulation using both standard clinical tests and thrombelastography (TEG) in 12 men who performed a LBNP and BL protocol in a randomized order. LBNP consisted of 5-min stages at 0, -15, -30, and -45 mmHg of suction. BL i...
