Introduction: Various types of vagus nerve stimulation are employed in the treatment of a range of conditions, including depression, anxiety, epilepsy, headache, tinnitus, atrial fibrillation, schizophrenia, and musculoskeletal pain. The objective of this study was to apply vagal stimulation to the neck area using standardised cold, and then analyse the level of vascular access discomfort experienced by individuals who underwent venous cannulation from the dorsal side of the hand prior to anaesthesia.

Materials And Methods: A total of 180 patients, aged 18-75, who were scheduled to undergo elective surgery, were categorised into three distinct groups: the Sham group (Group S), the Control group (Group K), and the Cold group (Group M), with each group consisting of 60 individuals.

Hematological parameters, including albumin and hemoglobin (Hb) levels and lymphocyte counts, are low-cost tests that can be used to determine inflammation and nutritional status. Recent studies have shown that inflammation plays a very important role in the development of carcinogenesis. The authors investigated whether preoperative hemoglobin, albumin, lymphocyte, and platelet (HALP) score can distinguish between benign and malignant causes in patients who are admitted to hospital and operated due to acute mechanical intestinal obstruction (AMIO).
