Summary
Drowning can cause hypothermia, leading to dangerous heart rhythm changes like ventricular fibrillation and Osborn waves. Early resuscitation is critical due to high mortality rates in drowning and hypothermia cases.
Area of Science:
- Emergency Medicine
- Cardiology
- Environmental Health
Background:
- Drowning is a leading cause of accidental death globally, particularly during summer.
- Key morbidities include anoxia, hypothermia, and metabolic acidosis.
- Cardiovascular complications often arise secondary to hypoxia and hypothermia.
Observation:
- A case report of a 16-year-old male treated for drowning.
- The patient presented with ventricular fibrillation and a giant J wave (Osborn wave) secondary to hypothermia.
- Electrocardiogram (ECG) changes are indicative of hypothermia following drowning.
Findings:
- Hypothermia in drowning victims can precipitate severe cardiac arrhythmias.
- Osborn waves on ECG are a significant indicator of hypothermia in drowning.
- Ventricular fibrillation is a critical cardiac event associated with severe hypothermia post-drowning.
Implications:
- This case highlights the importance of recognizing ECG changes associated with hypothermia after drowning.
- Prompt resuscitation and aggressive management of cardiovascular and respiratory issues are vital for improving survival.
- High mortality rates underscore the need for immediate and comprehensive medical intervention.

1.1K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.

01:23Acute Respiratory Failure-IV
687
Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...

01:29Disturbances in Heart Rhythm
3.5K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

1.1K
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...
