To the Editor, Cephalic vein in the wrist is a common choice for peripheral venous cannulation due to easy access and splinting as well as consistent anatomy. Unintentional radial artery cannulation during cephalic venous access over the radial styloid process is unlikely and rare. Here we report such a case while securing venous access. A 43 year-old lady was planned for total abdominal hysterectomy. The cephalic vein at her wrist was made prominent by manual compression and the skin was prepared with antiseptic solution. Cannulation of the vein over the right radial styloid process was started with an 18G cannula. The needle was withdrawn and the cannula advanced once blood was seen in the flash back chamber. Intravenous fluid transfusion set was connected. It was noted that there was a back flow of bright red blood into the transfusion set rather than free flow of fluid into the vein. We suspected arterial cannulation. On palpation, the tip of the cannula was felt anteromedially where a distinct arterial pulse was palpable (Figure 1). The cannula was removed and compression was applied over the puncture site to prevent bleeding and hematoma. No further problems like pain, distal ischemia or hematoma were noted in the limb. Anaesthesia and surgery were commenced after securing a new intravenous line in her left hand. At the insertion site of the cannula a distinct arterial pulse could be palpated revealing the presence of an artery near the cephalic vein. Figure 1: Cannula in the wrist with its tip (marked) anteromedially Inadvertent arterial cannulation during central venous cannulation is a common complication but is rare during peripheral venous cannulation. A few incidences have been reported during cephalic, basilic, cubital and saphenous vein cannulation. The most likely reason of arterial puncture during cephalic vein cannulation at the level of wrist is the presence of superficial radial artery. Normally the radial artery runs several millimeters deeper than the cephalic vein, so the risk of arterial cannulation is rare. 1 But in 0.5 to 1% of individuals, there is superficial radial artery, where the radial artery at the level of wrist crosses over the tendons which define the snuff box, rather than Corresponding author: Parineeta Thapa, MD, Assistant Professor, Department of Anaesthesiology and Critical Care, B.

JSAN 2015; 2 (1) running deep to it. 2 Unidentified arterial cannulation and injection of drugs into an artery can cause devastating complications like arterial thrombosis and ischemia of the limb distal to the injection site. Need for thrombectomy and surgical repair of the artery has also been reported. 3 Anticipation and early identification of this situation is important in preventing further harm to the patient. Use of arterial blood gas analysis and pressure transducer may be required at times when clinical judgement alone may fail, as in cases with hypovolemia. In our case we could trace the tip of the cannula going anteromedially into the direction of radial artery confirming its intraarterial location. Peripheral venous cannulation is performed after making the vein prominent and possibility of inadvertent arterial cannulation is seldom thought of. Our and similar other cases prompt us to routinely palpate the venipuncture site for arterial pulse prior to venous cannulation to avoid this potentially harmful situation. References 1.

It should provide knowledge, be original in authorship, be based on adequate records, and must have significant finding. Reviewers will evaluate the suitability of the manuscript for publication. The language of publication is English. The author should clearly specify the type of article being submitted. However, the category under which the article will be published will be decided by the editorial board. Preparation of Manuscripts: Manuscripts should be prepared according to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, at www.icmje.org. 1 Single-space manuscripts with 1-inch margins on all sides.

It is important for authors and reviewers to know that our
journal follows double blind peer review process. To ensure the integrity of the blind peer-review for submission to this journal, every effort should be made to prevent the identities of the authors and reviewers from being known to each other.

Manuscript Review Process We make every effort to complete the peer review process and notify the corresponding author as soon as possible after receiving a complete submission. All articles are evaluated by at least two editors. Selected manuscripts undergo further review, typically by 2-4 peer reviewers. Manuscripts are assessed based on their originality, importance of results, clarity of discussion, contribution of new knowledge, and potential impact on health, health care, policy, and future inquiry. We encourage authors to share their expertise by becoming a peer reviewer. Express your interest with an email to the executive editor. Information submitted or accepted for publication in the JSAN may be released to the media or the public only after it has been published in the JSAN, or after the corresponding author has been notified that the JSAN will not publish it. If the research represents thesis work of a residency program, it should be clearly mentioned in the disclosures. However, even before research is published in JSAN, authors may present the results at scientific meetings or conferences. 1 International Committee of Medical Journal Editors.
