| Abstract | Central venous catheterization is widely used in neonatology. Although ultrasonic guidance for central venous catheter placement is available, complications occur significantly more frequently in infants, especially neonates, than in adults. This study seeks to determine the characteristics, topographical conditions, regional relationships, and diameters of the venous structures of the upper extremity and the thoracic central venous system in extremely small preterm neonates (mean: 900 g). Nine formaldehyde-fixed preterm stillborns were prepared (mean 27 2/7 weeks' gestational age). The anatomical preparation involved the complete thoracic wall, neck and shoulder region, and preparation of the upper extremities. It was shown that the course of the internal jugular vein can be influenced by rotation of the head. Maximum head rotation (80°) to the contralateral side leads the internal jugular vein to overlap the common carotid artery and sharpens the confluence angle of the internal jugular into the brachiocephalic vein. We propose that this has the potential to result in dislocation of the catheter. Less rotation of the head (<30°) is favorable as the internal jugular vein and common carotid artery run in parallel. Commonly used central venous catheters (2F-4F) may not occlude the vascular lumen completely. Small central venous cannulation using a single-orifice catheter through arm veins (1F) may also not occlude peripheral vessels of the upper extremity (cephalic and basilic veins). The right internal jugular vein has a straight course, appears suitable for central venous access and less hazardous, especially when using stiff catheters. The use of small straight wire guides is recommended. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
