Cold vapor application is considered a promising intervention with the potential to alleviate side effects associated with anesthesia and surgery in the postoperative period. This study aims to determine the effect of cold vapor inhalation on dyspnea, thirst, nausea, and physiological parameters following laparoscopic inguinal hernia surgery.
Hypotheses (H1);
H1a: Patients administered cold vapor will report lower dyspnea severity compared to the control group.
H1b: Patients administered cold vapor will report lower thirst levels compared to the control group.
H1c: Patients administered cold vapor will report lower nausea severity compared to the control group.
H1d: Patients administered cold vapor will show significant differences in physiological parameters compared to the control group.

Other interventionCold steam application will be performed using a Hikoneb 906 S/LCD ultrasonic nebulizer, which will generate cold steam with distilled water. Device parameters will be optimally set to steam delivery level 5 (1-10), steam density level 5 (1-10), and steam temperature 1C0 (1C0-10C0). This application will be applied to the intervention group for 15 minutes after the baseline (T0) assessment. Cold steam will not be delivered directly to the airways but will be applied to the facial area, covering the mouth and nose area. A distance of approximately 20-30 cm will be maintained between the device's steam outlet and the patient's face.
Survey Form
The form developed by the researchers consists of a total of 13 questions and collects data on the demographic (age (year), gender, body mass index (kg/m² ), ect.) and clinical characteristics (American Society of Anesthesiologists-ASA score, perioperative fasting period (min), ect.) of the patients.
Modified Borg Scale (MBS) for Dyspnea
The MBS is a 12-point scale that rates dyspnea severity from 0 (no dyspnea) to 10 (intolerable dyspnea).
Numerical Rating Scale (NRS) for Nausea Level
The severity of postoperative nausea in patients will be assessed using the NRS, which is scored from 0 to 10 and created by researchers. Higher scores on this scale represent higher severity of nausea.
Surgical Period Thirst-Related Discomfort Scale (SPTRDS)
This six-item, three-point Likert-type scale has a single-dimensional structure. Items were rated as "did not bother" (0), "slightly bothered" (1), and "very bothered" (2). Higher scores on this scale represent higher severity of thirst.
