Correlation of sonographic measurements of the internal jugular vein with central venous pressure

Internal jugular vein collapsibility index associated with hypovolemia in the intensive care unit patients

“…The IJV collapsibility index can be applied to most ICU patients including those with mechanical ventilation on PEEP or vasopressor support, which were not included in previous studies [1,2]. Fig.…”

“…Keller et al [1] discussed the correlation of IJV aspect ratio (height/width) to estimate a CVP of 8 mmHg in spontaneously breathing patients. The measurement of end-expiratory IJV diameter in spontaneously breathing supine patient has shown high correlation with CVP [2]. In this study, we evaluated ICU patients who were euvolemic, hypovolemic, spontaneously breathing or on mechanical ventilation and with or without vasopressor support.…”

“…Assessment of intravascular volume status and hypovolemia can be challenging at times, especially when relying on physical examination and physiologic data in ICU patients [1,2,4]. Bedside echocardiography can estimate central venous pressure (CVP) based on evaluation of the inferior vena cava (IVC) distention and respiratory variation [4,6].…”

Epert Consensus on a Canadian Internal Medicine Ultrasound Curriculum

“…Three Delphi rounds were conducted to reach a consensus. These 16 topics included measurement of the height of the internal jugular vein, 29,30 inferior vena cava measurement, 31,32 pleural effusion and thoracentesis, 8,33,34 central line insertion and pneumothorax, 3,6,7,35,36 liver and spleen examination, 2,37 ascites and paracentesis, 9,38 the bladder, 14,39,40 cellulitis/abscess/aspirates, 41,42 arterial line insertion, 43 peripheral intravenous access, 44,45 and joint aspiration. 10 Although the evidence for the role of ultrasound in establishing peripheral intravenous access in adults is not as consistent as that in pediatric patients, 46 the group felt that learning this skill is unlikely to be harmful and may improve the care of patients.…”

Influence of tissue pressure on central venous pressure/peripheral venous pressure correlation: An experimental report

“…[1] Given the inherent risks associated with central venous catheterization, however, CVP monitoring has largely remained confined to the critically unwell. Recent reports of alternative modalities for obtaining CVP estimation [2][3][4][5] hold promise for utilization of fi lling pressure estimation in volume state assessment both prior to central line insertion and in those patients in whom central line placement is deemed unnecessary.…”
