Tying a surgical mask to prevent fogging

Alternative Agents to Prevent Fogging in Head and Neck Endoscopy

BACKGROUND The essential factor for diagnosis and treatment of diseases in head and neck endoscopy is the visibility of the image. An anti-fogging agent can reduce this problem by minimizing surface tension to prevent the condensation of water in the form of small droplets on a surface. There is no report on the use of hibiscrub(®) or baby shampoo to reduce fogging in the literature. The object...

Surgical Mask to Prevent Influenza Transmission in Households: A Cluster Randomized Trial

BACKGROUND Facemasks and respirators have been stockpiled during pandemic preparedness. However, data on their effectiveness for limiting transmission are scarce. We evaluated the effectiveness of facemask use by index cases for limiting influenza transmission by large droplets produced during coughing in households. METHODOLOGY AND PRINCIPAL FINDINGS A cluster randomized intervention trial w...

Oesophageal Vent-Laryngeal Mask to prevent aspiration of gastric contents.

Difference between continuous positive airway pressure via mask therapy and incentive spirometry to treat or prevent post-surgical atelectasis.

OBJECTIVE To assess the effect of early use of continuous positive airway pressure (CPAP) therapy to treat or prevent acute atelectasis in post-operative cardiac patients particularly smokers and elderly patients. METHODS A pilot study suggested enrolling at least 32 participants in each group to be significant. One hundred and eight patients from King Fahd Armed Forces Hospital, Jeddah, King...
