Studies were conducted by Chudari L S et al [3] to compare the anterior and posterior approaches of internal jugular venous cannulation, Chandralekha M V et al [5] for comparing palpation method and non-palpation method of internal jugular vein cannulation and Lamkinsi T et al [6] for evaluating best approach to cannulate internal jugular vein.
