Central venous catheters--the inability of 'intra-atrial ECG' to prove adequate positioning.
BACKGROUND The classic increase in P wave size, known as 'P-atriale', is a widely accepted criterion for determination of proper positioning of central venous catheter tips. Recent transoesophageal echocardiography (TOE) studies did not confirm intra-atrial position despite advancing the central venous catheter further than indicated by ECG guidance. We postulate that the pericardial reflection...
متن کاملThe intracavitary ECG method for positioning the tip of central venous catheters: results of an Italian multicenter study.
PURPOSE The aim of this multicenter study was to assess the feasibility, safety, and accuracy of the intracavitary ECG method for real-time positioning of the tip of different types of central venous catheters. METHODS A total of 1444 catheter insertions in adult patients were studied in eight Italian centers (539 ports, 245 PICCs, 325 tunneled CVCs, 335 non-tunneled CVCs). Patients with no v...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Central venous catheters are routinely placed in patients undergoing major surgeries where expected volume and hemodynamic disturbances are likely consequences. The incorrect positioning may give false central venous pressure (CVP) readings leading to incorrect volume replacement and other serious complications. 50 American Society of Anaesthesiologists grade II-IV patients aged 18-60 years wer...
متن کاملIntra- and extra-pericardial lengths of the superior vena cava in vivo: implication for the positioning of central venous catheters.
To reduce the possibility of cardiac tamponade, a rare but lethal complication of central venous catheters, the tip of the central venous catheter should be located above the cephalic limit of the pericardial reflection, not only above the superior vena cava-right atrium junction. This study was performed to measure the superior vena cava lengths above and below the pericardial reflection in ca...
