Drowning (cont.)

How is drowning treated?

Treatment begins at the water's edge. The American Heart Association recommends that if possible, one person is sent to activate Emergency Medical Services and call 911. Another is sent to bring an automatic external defibrillator (AED) to the victim's side.

If no pulse can be identified and the patient is not breathing, CPR should be started. Drowning is one of the special situations where hands-only CPR is NOT indicated. If there is a potential for a neck injury, special care needs to be taken to prevent further injury to the victim by keeping the neck and body in alignment.

If the patient is breathing but not awake, they should be placed on their side in the rescue position to prevent aspiration if vomiting should occur.

  • Further treatment by EMTs, paramedics, and staff at the hospital will depend upon the severity of the symptoms. Those patients who have no symptoms may require nothing more than observation.
  • Those who are in cardiopulmonary arrest will likely undergo CPR with attempts to restore a regular heart rhythm and heart-beat.
  • Those patients who have symptoms related to the function of their heart, lung, or brain will need further evaluation and treatment tailored to their specific circumstances and situation.
  • And unfortunately, for those who are found dead with no potential for resuscitation, further treatment or evaluation may not be indicated.

What are the complications of drowning?

  • Hypoxemia causing brain damage is the major complication in drowning victims who do not die.
  • Direct lung tissue damage caused by water aspirated into the lung can also occur and may lead to pneumonia and acute respiratory distress syndrome (ARDS).
  • If the drowning occurs in colder water, there is the risk of hypothermia or a drop in core body temperature.
  • Drowning may occur as a consequence of injury or illness. For example, cervical spine fractures (broken neck) due to diving injuries may result in breathing problems and subsequent drowning. Drowning can occur as a result of syncope or loss of consciousness in the water, due to a variety of medical conditions including heart attack and seizure.

How can drowning be prevented?

Most drownings are preventable, and simple steps can be taken to help with water safety.

  • Learn how to swim.
  • When in the water, use the buddy system.
  • Do not use alcohol or drugs when swimming or boating.
  • Supervise children closely around water and make certain they are the focus of your attention. Even bathtubs and buckets full of water can be dangerous.
  • Swimming pools should have barriers (fences, gates, alarms) to prevent children from entering unattended.
  • Learn CPR.

What is the prognosis for a drowning victim?

The prognosis for many drowning victims is poor. The brain does not tolerate lack of oxygen well and the amount of potential damage is dependent upon the time the patient spends hypoxemic in the water.

Even if the brain survives, acute respiratory distress syndrome (ARDS) may cause significant short and long-term problems as the lungs try to recover from their injuries.

The key to the treatment of drowning is prevention.
