We thank Sasani et al. for showing interest in our paper  and their valuable comments. We essentially agree with the point of view that the use of a high-frequency (7 MHz) linear array probe and a dynamic method is definitely desirable for using ultrasound (US) assistance in internal jugular vein (IJV) cannulation. 
However, the current study was mainly directed toward the practical situation in a cardiac surgery operation theater including space and cost constraints. The study was designed keeping in mind the utilization of already available gadgets and resources in this operation theater. The setup usually has a transesophageal echocardiography (TEE) machine along with a transthoracic echocardiography (TTE) probe which has a frequency (2-4 MHz). The sterile sheath required for the dynamic US technique was not available to us. The adult cardiac surgical population is also different from the kind of subject population used in the studies that have formed a part of meta-analysis supporting the use of US for IJV cannulation.  Keeping these patient and device factors into consideration, the current study aimed to compare the static US technique using the TTE probe supplied with the TEE machine with the conventional landmark technique in the adult cardiac surgical population.
