Significant physiological impact of wearing PPE inside operation theatre: A challenging scenario in this COVID-19 pandemic

Owing to COVID-19 pandemic, wearing personal protective equipment (PPE) and N95 mask inside an operation theatre has become a common practice. Subjective symptoms of suffocation, headache, dizziness, and lack of concentration while on PPE may at times become significant enough requiring oxygen therapy, removal of mask, or even doffing of PPE, which may increase the risk of being infected and at the same time compromising patient care. The reason behind such subjective symptoms may be multifactorial. We report here a 52-years-old anesthetist with a high body mass index, wearing PPE for a prolonged duration inside an operation theatre during a high-risk surgery encountered a similar episode. Being the lone anesthetist, he decided to oxygenate himself in an innovative way, thus, avoiding doffing and any undesirable event. With pandemic expanding rapidly such scenarios may be encountered often, identifying factors predicting such events and finding methods of oxygenation while wearing PPE may be extremely beneficial.
