The Editor,

We thank the author [1] for showing interest in our recently published article on central venous cannulation. [2] The author raises a pertinent issue of non-reliance of the color of blood and pulsatility in confirming the venous puncture in cyanotic patients. We entirely agree with this contention; we further state that before the advent of ultrasound in anesthesia practice, the only absolute confirmatory method of diagnosing venous cannulation was to transduce the catheter and obtain venous waveform and pressure. The blood gas analysis may not be reliable even in non-cyanotics, if patient is being ventilated with high fractional inspired oxygen concentration. The advent of ultrasound has definitely changed the scenario and can be extremely helpful in confirming venous cannulation; however, it has its own pitfalls as highlighted in the recent article where it was shown that a side-lobe artifact can lead to misinterpretation of arterial cannulation as venous cannulation. [3]
