Meta description: Regulatory update on a multicenter trial testing surgical and N95 masks to reduce exposure to surgical smoke among operating room nurses. The study is sponsored by Bartın University and Bartin State Hospital and is currently recruiting. In plain terms, a new trial examines whether standard surgical masks or N95 respirators provide better protection against surgical smoke for operating room staff. The study is registered at ClinicalTrials.gov with identifier NCT07404956 and is led by Bartın University in partnership with Bartin State Hospital in Turkey. Recruitment is active.
In this article we describe what has changed, who is affected, and what stakeholders should monitor as the study progresses. The information is drawn from a ClinicalTrials.gov record and sponsor disclosures dated 2026 02 13. Publication context is February 13 2026.

What changed in mask use for surgical smoke protection?
The study identifies two device arms that are typical in PPE assessments: a standard surgical mask and an N95 mask. The objective is to observe whether mask type influences exposure related indicators during procedures that generate surgical smoke. Reported information covers occupational exposure and health indicators including headaches, dizziness, nausea and vomiting, fatigue, eye irritation, abdominal discomfort, and changes in physiologic measures such as heart rate and SpO2. The description signals a focus on protecting operating room staff rather than treating patients. The design signals regulatory interest in comparing device performance and safety under real world use.
Who is affected by this trial and why should facilities care?
The targeted population comprises operating room nurses and other staff exposed to surgical smoke during procedures. Stakeholders such as hospital occupational health teams and surgical service leaders should watch for how mask selection may influence worker comfort and symptom burden, as well as vital sign stability. The sponsor notes the trial’s emphasis on worker safety and performance indicators relevant to occupational exposure. While results are not yet available, the trial description provides a framework for PPE decision making in high smoke environments and for policy discussions within health care facilities. A ClinicalTrials.gov link is provided for transparent access to trial specifics.
How is the trial designed and what outcomes are measured?
The trial compares two PPE devices in a surgical setting. Interventions are device based and consist of a surgical mask versus an N95 mask. Outcome measures include symptomatic events such as headache, dizziness, nausea and vomiting, fatigue, eye irritation, abdominal pain, and restrictions such as muscle weakness and discomfort. Physiologic parameters include heart rate and SpO2. The study context is occupational exposure to surgical smoke and aims to capture user experience and safety signals under real world conditions. Sponsorship is from Bartın University and Bartin State Hospital, with recruitment ongoing. The study page on ClinicalTrials.gov provides the official record and status.
What are the regulatory implications for device use in protecting against surgical smoke?
From a regulatory perspective this study aligns with evidence generation requirements for PPE used in health care settings. Findings could inform performance and safety claims for surgical masks and respirators when exposed to surgical smoke, consistent with MDR Annex XIV expectations for conformity assessment and post market evidence. Regulators will scrutinize study design, exposure context, outcome definitions, and reporting practices. The existence of a public record on ClinicalTrials.gov enhances transparency and may influence hospital policy development and supplier guidance on PPE choices in operating rooms. Devices involved are standard PPE and the study notes the two mask types under evaluation.
What are the next steps and timelines for the study?
Next steps include continued recruitment by the sponsor institutions in Turkey and formal data collection under the current protocol. The official record on ClinicalTrials.gov supplies the identifier NCT07404956 and notes the term medical device in the study description. If recruitment progresses, investigators will plan data analysis and dissemination in accordance with sponsor guidance and applicable regulatory requirements. Hospital leaders and occupational health professionals should monitor updates to align PPE policies with any forthcoming evidence from this trial. We reiterate that the study is currently in the recruitment phase.
FAQ
- 1. What is the purpose of this trial? The trial compares two mask types to determine if surgical masks or N95 respirators provide different levels of protection against surgical smoke exposure for operating room staff. It also records related symptoms and physiological indicators.
- 2. Who can participate? The target population includes operating room nurses and other OR personnel who may be exposed to surgical smoke during procedures. Specific inclusion criteria are defined in the trial registry.
- 3. Where can I learn more? The ClinicalTrials.gov page for NCT07404956 is the primary source for official trial details, status updates, and contact information.
Conclusion and implications for practice
At this stage the trial represents a structured effort to generate comparative PPE performance data in a real world surgical environment. The regulatory value lies in the potential to inform PPE selection criteria and safety guidance for operating room teams. Stakeholders should track recruitment progress and plan for a critical appraisal of any published results in light of MDR safety and performance expectations.
