in order to determine the effect of valsalva maneuver and head rotation on the internal jugular vein (ijv) diameter and cross-sectional area and overlap with the carotid artery (ca) and find the best technique for safe cannulation of the ijv and decrease the risk of ca puncture, the diameter of both the ijv and the ca and percentage of overlap between the two vessels and cross-sectional area of...

background: by increasing the survival of immature newborns, intravenous access methods, used to provide intravenous therapy, became more important. more attention has been recently paid on peripherally inserted central venous catheters in newborns, although it is yet unknown in iran. in this study, we tried to discover the barriers to spread the usage of peripherally inserted central venous ca...

Background: Central venous catheterization is a procedure that is being performed frequently especially in critical clinical settings. In such conditions, good knowledge of the surface anatomy of venous structures is vital to avoid possible complications which could result in life-threatening situations such as bleeding and pneumothorax. Considering the difference between venous anatomy of chil...

conclusions most of the catheter-related deaths were due to severe sepsis and hemothorax, and a significant relationship was noted between infection and both the mortality rate and catheterization duration. a significant relationship was also evident between birth weight and infection rates. background developments in the use of central venous catheters have improved the treatment of critically...

Background: In many clinical situations, knowledge of central venous pressure (CVP) is important.  Measurement of CVP is not always possible. Objective: To determine if intraocular pressure (IOP) can be used as an estimate for CVP. Methods: IOP and CVP were measured concurrently in 30 candidates of coronary artery bypass graft surgery.  Those with carotid artery or jugular venous diseases as we...

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 ...
