Congenital diaphragmatic hernia: implications for nitrous oxide use in dentistry.
The development of diaphragmatic hernias, their associated physical and diagnostic signs and symptoms, and the potential complications with nitrous oxide use are presented with a case report. Depending upon the location and extent of the diaphragmatic defect, portions of the stomach, omentum, liver and/or intestine can occupy a portion of the thoracic cavity. Nitrous oxide's solubility properties allow for rapid expansion of the herniated bowel, resulting in compression of the thoracic organs or strangulation of the herniated abdominal viscera. The presence of a diaphragmatic hernia may necessitate a change in sedation or anesthesia plans to eliminate the use of nitrous oxide during prolonged procedures.
