A surgical face mask, also called a facial protective device, is designed to be worn by medical professionals during surgical procedures. Surgical masks are designed to prevent infections from infecting operating personnel and patients by trapping microorganisms in liquids and aerosols injected into the patient’s mouth and nose by the surgeon or other operating personnel. Medical devices that are used to protect surgical personnel from infections they can bring about during or after surgery are called surgical masks. Infection can also occur through foreign materials that enter the nasal passages of the patient or from leaks from the patient’s body that reach the surgical area. These leaks can lead to the entry of microorganisms which can cause infections when they multiply and feed on the infected areas.
Infection may be prevented through the use of masks. Masks that prevent air from entering the nose while still allowing some air to leave so that one can breathe easily are ideal for these situations. Some surgical masks work by providing additional airway protection for the patient, preventing mucus and other irritants from entering the nose and throat.
Another study reported that Dacron garments increase airflow by reducing sweat when doctors wear them. The garments are made of two layers of fabric and a layer of foam for increased flexibility. This means that doctors do not have to adjust their face masks as often. The study also showed that Dacron reduces sweating because the fibers absorb moisture from the air instead of letting it evaporate. The material traps body heat and pulls it away from the skin surface, leaving the skin cool and dry.
Doctors who wear a breathing mask called a “Covid-19” type face mask while they are working in a sick patient’s ward have shown lower incidences of microbial contamination, bacterial contamination and allergic reactions. The manufacturers of this type of mask have found that while they are worn, the patient’s level of stress and moods do not change. In fact, the staff report that they feel more alert and focused after wearing the masks. Patients who are administered anesthetic or sedation have shown decreased risk of infection and a decrease in allergic reactions to anesthesia. While incontinence is a concern, the study found that workers who wear a face mask while they are under anesthesia experienced less incontinence than those who did not wear a mask. They also had lower urine and blood pressure readings and showed fewer signs of allergic reactions.
Another type of doctor who may benefit from a face mask are nurses and hospital employees who may need to wear them to shield their faces from vomiting or choking hazards. Workers should consider purchasing a hard-face mask that is sturdy enough to withstand the most vigorous coughing. Some of these nursing staff masks also include a non-sterile mouth piece to further protect the worker. These nurses and hospital employees may be at greatest risk of adverse reactions when they are operating or moving heavy objects such as large pieces of equipment. For these types of workers, wearing a hard face shield during these activities can help to reduce chances of irritation or injury.
Face shields can also be worn by doctors and medical staff on a daily basis. Doctors wear face shields when they perform autopsies on patients or when they inject patients with medication. These professionals are not exposed to the same risks of wearing a face mask as other healthcare workers but they do still need to consider wearing protective gear. The same goes for teachers or parents who wish to shield their children during recesses or summer field trips.
