Accurate, reliable, and sufficient data is required to reduce the burden of drowning by targeting preventive measures and improving treatment. Today's drowning statistics are informed by various methods sometimes based on data sources with questionable reliability. These methods are likely responsible for a systematic and significant underreporting of drowning. This study's aim was to assess the 30-day survival of patients with out-of-hospital cardiac arrest (OHCA) identified in the Danish Cardiac Arrest Registry (DCAR) after applying the Danish Drowning Formula. ⋯ This study was registered at ClinicalTrials.gov before analyses (NCT05323097).

Acidosis has been reported to cause ST-segment elevation. We presented a woman with a history of rectal adenocarcinoma experienced cardiac arrest during the contrast-enhanced computed tomography examination. When spontaneous circulation returned, arterial blood gas revealed she had severe respiratory acidosis, and bedside electrocardiogram showed ST-segment elevation in anterior precordial leads. ⋯ Echocardiography revealed no abnormality of cardiac cavity size, segmental wall motion, or pericardial echo. Carcinoma metastasis in the peritoneal cavity and lungs was detected on the contrast-enhanced computed tomography scan while the heart was not involved. The ST-segment regressed and the respiratory acidosis was corrected after she received mechanical ventilation which strongly suggested the association between acidosis and the electrocardiogram changes.
