Gastric mucosal tears and wall micro perforations after cardiopulmonary resuscitation in a drowning case

Hypothesized mechanisms of death in swimming: a systematic review

BACKGROUND

The study aims to update the specific classification of mechanisms of death in swimming and to demonstrate these categories are reasonable, by analyzing more characteristics of death cases, evaluating the available evidence and determining their quality.

METHODS

Original articles were queried from PubMed, Web of Science, Embase databases, Cochrane Library, and Scopus. Included studies, which were evaluated as level 4 evidence or higher according to the Oxford Centre for Evidence-Based Medicine, discussed hypothesized mechanisms of death in swimming. Parameters analyzed in this study included decedents' characteristics, outcome measures, findings, methodological index for non-randomized studies (MINORS), and critical evaluation of each study classified by death mechanism.

RESULTS

A total of twenty-five studies were included for further analysis: fourteen were associated with cardiovascular diseases, two were about cerebrovascular diseases, two contained respiratory diseases, seven were about hazardous conditions and three contained other drownings, which provided evidence for mechanisms of death.

CONCLUSIONS

It is found that cardiovascular disease is the main cause or contributing factor of death in swimming. Respiratory diseases and cerebrovascular diseases are difficult to be definitive mechanism categories due to insufficient evidence. Hazardous conditions appear to be one of the possible risk factors because there are more cases of deaths from unsafe environments in swimming, but further statistics and research are still needed to support this view. Our study may have important implications for developing potential prevention strategies for sports and exercise medicine.

Complete gastroesophageal junction avulsion after near drowning: A case report and review of literature

•

GE junction injuries are in pediatric population.

•

These injuries are associated with high morbidity and mortality.

•

A high index of suspicion and prompt recognition is needed.

Introduction

Gastroesophageal (GE) junction injuries are rare in the pediatric population. A complete GE junction separation in a child secondary to trauma has not reported in the literature yet.

Presentation of case

A 14-year-old boy presented with a complete GE junction avulsion after a near-drowning experience. He underwent immediate damage control surgery and delayed gastric pull-up esophageal reconstruction in 3-months. At the most recent clinic visit 5 months from the reconstruction, he can tolerate a regular diet without difficulty and is gaining weight and recovering well.

Conclusion

Complete GE junction injuries and avulsions are rare with limited data to guide management. These injuries are associated with mortality rates from 25% to 33%, therefore, high index of suspicion, prompt recognition and careful surgical planning is needed for favorable outcomes.

Mallory-Weiss Tear After Cardiopulmonary Resuscitation in a Patient Suffering From Acute Myocardial Infarction

A report of a 79 year old male patient suffering from acute myocardial infarction with Mallory-Weiss tear after successful cardiopulmonary resuscitation(CPR) by emergency medical technician in the swimming pool is presented. Successful percutaneous coronary intervention(PCI) was done after appropriate transfusion. The patient survived and discharged without major complications after admitting 11days in the hospital. Importance of CPR in AMI patient is reiterated as complication such as Mallory-Weiss tear may arise.

Physiology Of Drowning: A Review

Drowning physiology relates to two different events: immersion (upper airway above water) and submersion (upper airway under water). Immersion involves integrated cardiorespiratory responses to skin and deep body temperature, including cold shock, physical incapacitation, and hypovolemia, as precursors of collapse and submersion. The physiology of submersion includes fear of drowning, diving response, autonomic conflict, upper airway reflexes, water aspiration and swallowing, emesis, and electrolyte disorders. Submersion outcome is determined by cardiac, pulmonary, and neurological injury. Knowledge of drowning physiology is scarce. Better understanding may identify methods to improve survival, particularly related to hot-water immersion, cold shock, cold-induced physical incapacitation, and fear of drowning.
