Abstract:
Vomiting and aspiration of gastric contents into the airways and lungs is a common and well-known clinicopathological entity. This phenomenon might also occur in underwater diving, where it can lead to life-threatening or fatal situations. This article presents two incidents involving diving-related vomiting with associated aspiration of gastric contents. One case, a 39-year-old commercial diver using a full-face diving mask, was fatal and the other was a 33-year-old, female recreational scuba diver in whom underwater vomiting was complicated by pulmonary aspiration of a solid foreign body (a peanut) into the right lower lobe bronchus. The peanut was successfully removed and, following bronchoscopic pulmonary lavage, the patient made an uneventful recovery. The causes and consequences of nausea and vomiting within the underwater environment are discussed and possible interpretative problems are highlighted.
