Sir,
We would like to convey our gratitude to the readers for showing interest in our article.[1] We agree that intravenous (i.v.) cannula should not be used for arterial cannulation due to risk of inadvertent arterial injection. We proposed the use of intravenous cannula for arterial cannulation in resource-limited settings which are not uncommon in our country.[2] To avoid accidental intra-arterial injections, drug port should be covered with surgical adhesive tape and labelled as arterial in bold letters [Figure 1]. This is routinely done at our institute to prevent such complications. | Figure 1: Drug port is covered with surgical adhesive tape and labelled as arterial in bold letters

We also agree that the modification suggested by us is not applicable to B Braun® i.v. cannula and is more suitable for Primaflon i.v. cannula (Lamed Healthcare Pvt. Ltd.).
The alternative method suggested by the authors is interesting, but it should be noted that there is enough reservoir in the flashback chamber of arterial cannula. Hence, it may not be necessary to modify the cannula. The modification suggested by the authors opens the closed system and may lead to bleeding, soiling and increased risk of infection. In addition, connecting a 2-mL syringe to any cannula (arterial/venous) increases the bulk of the system and makes the procedure more difficult, especially for trainees.
We recommend a dedicated arterial cannula for arterial pressure monitoring; however, if it is unavailable, one can use i.v. cannula after taking due precautions.
