Effect of Cold Application to Different Side Neck Region on Venous Cannulation Pain

Intravenous (iv) cannulation is one of the most common applications performed by anesthesiologists in and outside the operating room. It is necessary to provide vascular access before any anesthetic procedure. Venous cannulation is a moderately painful procedure and is uncomfortable for patients, and the pain of intravenous cannulation may increase the patient\'s stress. Various methods are used to reduce cannulation pain. Stimulation of the N. Vagus is also among these methods (1). The branches of N. Vagus are densely located under the skin in the auricle and on the lateral aspect of the neck. It is thought that the dominance of the right and left vagal nerve over different systems is different. For example; While the right vagal branches are thought to be more effective on heart rate, the left side vagal branches are thought to be more effective in the treatment of refractory epilepsy. Purpose: Our aim in this study is to evaluate the vascular access pain in our patients to whom investigator applied venous cannulation from the back of the hand before anesthesia, by stimulating the Vagus Nerve with cold application to the neck area on both sides separately.
