This study was conducted to compare the effect of surgical mask and N95 mask use on physical symptoms due to surgical smoke in operating theatre nurses. The study, which was conducted in a single-group prospective quasi-experimental design, was completed with 38 nurses in the operating theatre unit of a state hospital in the Western Black Sea Region. Data were collected for four weeks using the Descriptive Information Form, Numerical Rating Scale and Symptom Follow-up Form. According to the findings, muscle weakness, myalgia in the upper extremities and muscle cramps were statistically significantly less in nurses using N95 masks. Respiratory parameters, watery eyes and redness were significantly lower in nurses using surgical masks. As a result, it was determined that the type of mask was effective on the incidence of physical symptoms related to surgical smoke.

Surgical Smoke-Related Physical Symptom Severity (Total NRS Score)
The severity of physical symptoms related to surgical smoke exposure in operating room nurses, including headache, abdominal pain, nausea and vomiting, fatigue/weakness, loss of appetite, and dyspnea, was assessed using the Numeric Rating Scale (NRS). Each symptom was rated on a standardized numeric scale, and a total symptom severity score was calculated by summing the individual symptom scores. Higher scores indicate greater symptom severity.
Time frame: Five days per week for a duration of four weeks both preoperatively and postoperatively
