It’s becoming increasingly common to use nonoperating room anesthesia (NORA) for gastrointestinal procedures as new technology makes these procedures easier.
The largest number of nonoperating room anesthesia (NORA) cases are gastrointestinal procedures; an estimated 18 million of these procedures are carried out every year in America alone. The growing popularity of NORA when it comes to this type of procedure can be attributed to medical advances made in gastrointestinal procedures as well as an aging population with a higher rate of comorbidities and an increasing focus within the health system on having cheaper and less invasive medical procedures.
It’s no longer necessary to have access to a full operating room to carry out some common gastrointestinal procedures successfully; to date, procedural oxygen masks POMs) have been most frequently used for esophagogastroduodenoscopy (commonly known as endoscopy), endoscopic ultrasound, and endoscopic retrograde cholangiopancreatography (which combines upper gastrointestinal endoscopy with X-rays).
Unfortunately, in 50% of gastrointestinal procedures performed under NORA, at least some respiration complications occur. POM cannulas, if used in accordance with a valid clinical protocol, generally reduce the risk of hypoxia; POM delivers nearly twice the FiO2 (fraction of inspired oxygen) of standard EtCo2 (end tidal carbon dioxide) cannulas. This provides a useful buffer for health professionals should things go wrong.
POM is also ideal for patient recovery following endoscopic procedures. POM membranes return to a closing state (maintaining prescribed oxygen levels during recovery) when tubes used during the procedure have been removed. Unlike traditional endoscopy equipment (such as the nasal cannula) the POM covers the patient’s mouth and nose, acting as a protective barrier between patient and practitioner. It is particularly useful in endoscopy suites where viruses and bacteria are an ever-present issue, especially today, with the existence of COVID-19, an ongoing issue for health practitioners. In addition to gastrointestinal procedures, POM is also suitable for bronchoscopy (examining the airways).
