due to catheter migration has been reported.[3] Arterial waveform showed by a CVC generally indicates inadvertent arterial insertion.[4] Accidental position of CVC in the left internal thoracic vein or the pericardiophrenic vein mimicking as arterial waveform has also been reported.[5] The author concluded the “arterial” waveform by CVC was due to transmission of pulse waves of adjacent cardiac...

As there is no other measurement of right ventricular preload, central venous pressure (CVP) measurement provides unique and important haemodynamic information. CVP is not measured routinely in neonatology and there is a shortage of data in the ventilated neonate. CVP was measured in 62 ventilated neonates. Thirteen had respiratory disorders (28-42 weeks' gestation, birth weight 860-4390 g) and...

BACKGROUND Despite a previous meta-analysis that concluded that central venous pressure should not be used to make clinical decisions regarding fluid management, central venous pressure continues to be recommended for this purpose. AIM To perform an updated meta-analysis incorporating recent studies that investigated indices predictive of fluid responsiveness. A priori subgroup analysis was p...

A 70-year-old man had the superior vena cava syndrome. At thoracotomy a retained central venous pressure line was found to be the cause of venous thrombosis at the outlet of the superior vena cava into the right atrium. A retained central venous pressure catheter and catheter-induced venous thrombosis should be added to the list of causes of the benign form of the superior vena cava syndrome.

OBJECTIVE To determine whether central venous pressure and fluid balance after resuscitation for septic shock are associated with mortality. DESIGN We conducted a retrospective review of the use of intravenous fluids during the first 4 days of care. SETTING Multicenter randomized controlled trial. PATIENTS The Vasopressin in Septic Shock Trial (VASST) study enrolled 778 patients who had s...

abstract we report a 54-year-old woman with the history of end-stage renal disease (esrd) who was admitted to our hospital because of volume overload. due to long-term use of peripheral veins and arteriovenous fistula (avf) failure, central venous catheterization was the only choice for hemodialysis. she developed right upper extremiti’s pain and paresis during hemodialysis. a posteroanterior c...

background: the current study was designed to compare the complications and adverse eff ects of central venous catheter (cvc) insertion under ultrasound guidance in patients with and without coagulopathy. materials and methods: in this clinical trial,59 patients who needed cvc for various reasons were enrolled. patients were divided into two groups of those with and without coagulopathy based o...

We evaluated the hypothesis that venous congestion (increased venous volume), as reflected by venous hypertension (increased venous pressure), can arise when the right ventricle is unable to elevate the pulmonary arterial pressure sufficiently to propel the cardiac output through an anatomically inadequate or inappropriately constricted pulmonary vasculature. Changes in venous pressure were eva...

To determine the role of the pericardium in man, ventricular function was studied in 20 patients who underwent pericardiotomy during coronary artery bypass surgery. Left and right ventricular function curves were generated before and after pericardiotomy by changing body position to alter venous pressure. Central venous (0--14 mm Hg) and pulmonary wedge pressures (1--25 mm Hg) ranged over norma...
