What this trial studies

This single-group prospective quasi-experimental study enrolled 38 sterile operating room nurses at a state hospital in Bartın, Turkey. Participants wore surgical masks and N95 masks according to protocol for at least four hours per day over a four-week period, with symptoms recorded using a Descriptive Information Form, Numerical Rating Scale, and Symptom Follow-up Form. Investigators compared rates of musculoskeletal, respiratory, ocular, and other physical symptoms between mask types. Results indicated fewer musculoskeletal complaints (muscle weakness, upper-extremity myalgia, cramps) with N95 masks and fewer respiratory and ocular complaints (watery eyes, redness) with surgical masks, leading to the conclusion that mask type affected symptom incidence.

Who should consider this trial

Good fit: Ideal candidates are sterile operating room nurses aged 18 or older who work at least four hours per day, five days per week, can wear both surgical and N95 masks continuously during shifts, and can provide informed consent.

Not a fit: Nurses with chronic respiratory, musculoskeletal, neurological, or dermatological conditions, pregnant staff, those in supervisory or non-sterile roles, or those planning unit changes were excluded and may not benefit from the findings.

Why it matters

Potential benefit: If successful, choosing the more appropriate mask could reduce occupational symptoms from surgical smoke and improve comfort and safety for operating room nurses.

How similar studies have performed: Previous research has documented health risks from surgical smoke and some protective effects of respiratory protection, but direct comparisons between surgical masks and N95 respirators for these specific symptoms remain limited.
