If the drowning occurs in colder water risks include hypothermia or a
drop in body temperature. (If the body temperature drops below 95F (35C) get
medical attention immediately.)
Cervical spine fractures may occur in diving injuries associated with
drowning.
Does the type of drowning matter?
There have been a variety of theories reported regarding the potential
responses of the body to different drowning situations. Most discuss dry vs. wet
drowning and salt vs. fresh water drowning.
Wet vs. Dry Drowning
Most drownings are unwitnessed, and the victim is found floating. While only
a small amount of aspirated water is required to cause significant problems with
lung function, it is the prolonged submersion time and lack of breathing that
causes morbidity due to hypoxemia.
Approximately 10%-20% of drowning victims have dry drowning, but even most
wet drowning victims have less than 4cc/kg of water found in their lungs. For a
50 pound child, this amounts to less than 3 ounces.
Salt vs. Fresh Water Drowning
In the lung, the breathing tubes (trachea, bronchi, bronchioles) branch into
smaller and smaller segments until they end in an air pocket called an alveolus
(plural alveoli). This is the part of the lung where air and red blood cells in
capillary blood vessels come near enough to allow the transfer of oxygen and
carbon dioxide between the two. Alveoli are covered with a chemical called
surfactant that allows the air pocket to open and close easily when breathing
occurs.
When fresh water enters an alveolus, it destroys the surfactant and causes
the alveoli to collapse, unable to open with breathing. A ventilation-perfusion
mismatch occurs in which the body sends blood to parts of the lung that lack
oxygen, resulting in a decrease in the concentration of oxygen in the blood.
Salt water doesn't destroy surfactant, rather it washes it away and damages
the membrane between the alveolus and the capillary blood vessel. One again, the
body sends blood flow to areas of the lung that aren't able to provide it
oxygen, and hypoxemia occurs.
Regardless of the type of water, lung function is compromised, and hypoxemia
occurs. In some circumstances,
electrolyte abnormalities may occur with fresh
water drowning.
Pneumonia is inflammation of one or both lungs with consolidation. Pneumonia is frequently but not always due to infection. The infection may be bacterial, viral, fungal or parasitic. Symptoms may include fever, chills, cough with sputum production, chest pain, and shortness of breath.
Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Heart attack happens when a blood clot completely obstructs a coronary
artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical
instability of the heart.
Hypoglycemia is a syndrome caused by low blood sugar. Symptoms of hypoglycemia include palpitations, trembling, intense hunger, sweating, nervousness, and weakness. Consuming lifesavers, table sugar, soda, and juice are good treatment options for hypoglycemia.
Epilepsy is a brain disorder in which the person has seizures. There are two kinds of seizures, focal and generalized. There are many causes of epilepsy. Treatment of epilepsy (seizures) depends upon the cause and type of seizures experienced.
Rhabdomyolysis is a rapid deterioration and destruction of skeletal muscle. Some of the causes of rhabdomyolysis include severe burns, muscle trauma, coma, seizures, electrolyte imbalance, medications (statins), viruses, bacteria. Treatment of rhabdomyolysis depends on the cause.
Sudden cardiac arrest is an unexpected, sudden death caused by sudden cardiac arrest (loss of heart function). Causes and risk factors of sudden cardiac arrest include (not inclusive): abnormal heart rhythms (arrhythmias), previous heart attack, coronary artery disease, smoking, high cholesterol, Wolff-Parkinson-White Syndrome, ventricular tachycardia or ventricular fibrillation after a heart attack, congenital heart defects, history of fainting, and heart failure, obesity, diabetes, and drug abuse. Treatment of sudden cardiac arrest is an emergency, and action must be taken immediately.
Seizures are divided into two categories: generalized and partial. Generalized seizures are produced by electrical impulses from throughout the brain, while partial seizures are produced by electrical impulses in a small part of the brain. Seizure symptoms include unconsciousness, convulsions, and muscle rigidity.
Acute respiratory distress syndrome (ARDS) is a lung condition in which trauma to the lungs leads to inflammation of the lungs, accumulation of fluid in the alveolar air sacs, low blood oxygen, and respiratory distress. Causes of ARDS include: pneumonia, aspiration, severe blow to the chest, sepsis, severe injury with shock, drug overdose, and/or inflamed pancreas. Treatment for ARDS include extra oxygen, and/or medication.
Managing your diabetes is important. The goal of diabetic therapy is to control blood glucose levels and prevent the complications of diabetes. Information about exercise, diet diet, and medication will help you manage your diabetes better. Blood glucose reagent strips, blood glucose meters, urine glucose tests, tests for urinary ketones, continuous glucose sensors, and Hemoglobin A1C testing information is also provided in this article.
Children's health is focused on the well-being of children from conception through adolescence. There are many aspects of children's health, including growth and development, illnesses, injuries, behavior, mental illness, family health and community health.
First aid is a complicated subject and it is situation-specific. First aid is the help and medical assistance that someone gives, not only to an injured person, but to a person who is sick. Preparedness is a key element of first aid, like having basic medical emergency kits in your home, car, boat, or RV. Cuts, puncture wounds, sprains, strains, nosebleeds are one type of injury that may require first aid; heart attacks, strokes, seizures, and heat stroke are examples of more critical first aid emergencies.
Natural diasters such as a hurricane can take a toll on family, friends, and neighbors. Both physiological and psychological stresses can be devastating. Learn how to prepare for a hurricane like food storage, safe water, first aid measures, cleaning mold, wearing protective gear, preparing for electrical hazards, avoiding carbon monoxide, avoiding physical injuries and hazardous materials, preventing drowning, reducing the risk of thermal stress, and preventing fatigue related injuries.
