Practices for the Treatment of Drowning: A Comprehensive Guide

In drowning emergencies, immediate action is critical. The treatment of drowning includes assessing the situation, performing a rescue, and administering resuscitation. This article details these life-saving steps to help you act swiftly and effectively, increasing the chances of survival and recovery.

Key Takeaways

• Immediate response and rapid rescue are critical following a drowning incident, as hypoxia can lead to serious outcomes.

• Effective resuscitation requires both rescue breaths and chest compressions, with specific CPR guidelines for adults and children.

• Post-rescue care, including airway management, oxygen supplementation, and careful monitoring, is essential for stabilizing drowning victims.

Initial Assessment and Rescue

The first moments of a drowning incident are vital. Contrary to popular belief, drowning is often a silent event, with victims unable to call for help as they struggle. A rapid response is critical; hypoxia, or lack of oxygen, often leads to death and long-term damage in drowning cases. Victims who are motionless or submerged, including a drowning patient or a drowning person, should be treated with the utmost urgency, and rescue efforts should never be abandoned prematurely to prevent a non fatal drowning or a fatal drowning. Drowning incidents require immediate attention to ensure the best possible outcomes.

Safety is paramount during the rescue process, both for the victim and the rescuer, especially in turbulent water conditions. Protecting the cervical spine during extraction is vital to prevent further injury. Rescuers must ensure that they do not assume the individual is beyond saving unless there are clear signs of death.

After safely removing the victim from the water, immediate resuscitation efforts should commence, including checking for breathing and pulse, and starting CPR if necessary. Remember, every second counts in these critical moments of rapid rescue.

Immediate Resuscitation Efforts

When it comes to resuscitation, speed and precision are key. Important steps include:

• Initiate two rescue breaths as soon as it’s safe to do so, starting with five breaths before moving on to chest compressions.

• Immediately evaluate the victim’s vital signs to determine the need for CPR.

• Focus on airway management, as drowning victims often have significant vomitus that requires suctioning.

In these situations, avoid compression-only CPR; both breaths and compressions are required. Key CPR guidelines include:

• For children, the recommended CPR compression-to-breath ratio is 15:2.

• For adults, the recommended CPR compression-to-breath ratio is 30:2.

• Use an automated external defibrillator (AED) promptly in cases of ventricular fibrillation to restore normal heart rhythm.

Resuscitation efforts aim not only to revive the heart and lungs but also to prevent long-term neurological damage. The quicker the oxygen flow is restored, the better the chances of full recovery, especially when cardiopulmonary resuscitation is administered promptly.

Prehospital Care Strategies

Once the initial resuscitation efforts are underway, the focus shifts to stabilizing the patient for transport to the hospital. Key steps include:

• Continuous monitoring of vital signs to ensure stability.

• Maintaining a clear airway for effective oxygenation.

• Providing supplemental oxygen to improve saturation and support respiratory function.

• Promptly correcting hypoxemia and acidosis.

Emergency responders should be trained in specific techniques for managing drowning victims effectively. Performing the Heimlich Maneuver on drowning victims is not recommended, as it can hinder resuscitation efforts.

Emergency Department Management

At the emergency department, the primary focus is immediate resuscitation and initial treatment of acute respiratory distress syndrome and emergency care. Providing 100% oxygen and evaluating for hypoxemia are crucial first steps.

The emergency department team will use various airway management techniques, including PEEP and CPAP/BiPAP, and may implement therapeutic hypothermia to improve outcomes.

Airway Management

Effective airway management is vital for treating drowning patients with respiratory impairment. Intubation is necessary if the victim cannot maintain adequate oxygenation or needs airway protection. For those with the following conditions, endotracheal intubation and PEEP should be considered:

• Poor respiratory effort

• Altered sensorium

• Severe hypoxemia

• Severe acidosis

• Significant respiratory distress

Stabilizing the airway immediately upon arrival at the emergency department is critical. Suction may be needed to clear the airway of liquids before intubation, and bronchoscopy might be required to remove foreign material or vomitus plugs.

The initial respiratory rate for drowned patients should be set to 35 breaths per minute or less, with a recommended tidal volume of 6 mL/kg of ideal body weight.

Positive End-Expiratory Pressure (PEEP)

PEEP plays a crucial role in improving oxygenation and lung mechanics during the treatment of drowning patients. By maintaining functional residual capacity in the lungs, PEEP helps enhance oxygenation, making gas exchange more efficient. Additionally, the application of PEEP reduces the risk of atelectasis, a common complication in intubated drowning patients.

Therapeutic Hypothermia

Therapeutic hypothermia can notably improve outcomes for drowning patients. Key points include:

• Typically maintained for 12-72 hours

• Target core temperature range of 32-34°C

• May impede neurologic examination

• Primary benefit is reducing neurological damage and improving overall outcomes.

Extracorporeal Membrane Oxygenation (ECMO)

Consider ECMO for drowning patients if persistent hypoxia cannot be managed with conventional methods. This advanced technique provides oxygenation and ventilation support, and often requires consultations with emergency cardiovascular care, intensive, or trauma surgical specialists.

Managing Complications

Post-drowning complications can be severe and require careful management. Volume depletion and acidosis often require isotonic fluid therapy and possibly inotropic agents for cardiovascular support.

Pulmonary edema, resulting from surfactant washout, can obstruct airway management and requires careful treatment to promote gas exchange. Secondary complications like electrolyte imbalances and seizures must also be monitored and managed.

Volume Depletion and Acidosis

Recommendations for treating volume depletion after drowning include:

• Administer isotonic crystalloid (20 mL/kg) or colloid.

• Rapid isotonic fluid expansion may be required due to potential intravascular volume depletion.

• Provide inotropic support if necessary, which can include the use of dopamine and/or dobutamine.

• Maintain normoglycemia to reduce mortality and brain sensitivity to injury.

For managing swallowed water, an orogastric tube may be needed if head or facial trauma is suspected, or a nasogastric tube can be used to remove swallowed water and debris.

Pulmonary Edema

Noncardiogenic pulmonary edema can occur due to extreme negative intrathoracic pressure during drowning, leading to decreased lung compliance. Ventilation-perfusion mismatches contribute to hypoxemia in drowning patients with pulmonary edema.

Effective management focuses on improving gas exchange and addressing these mismatches.

Cold Water Drowning Considerations

Cold water drowning poses unique challenges, particularly the high risk of cardiac and central nervous system dysfunction. However, cold water submersion can also have a protective effect, especially for children, by reducing oxygen requirements and delaying hypoxic damage.

Victims submerged in cold water for extended periods can experience reduced oxygen requirements, providing a critical window for rescue and in water resuscitation for a near drowning victim.

Long-Term Monitoring and Rehabilitation

Drowning survivors require:

• Long-term monitoring and rehabilitation.

• Induced hypothermia to help mitigate neurological damage by slowing metabolic processes, which can significantly affect the drowning outcome and lead to drowning injuries.

• Ongoing medical follow-up to assess and manage potential complications, particularly neurological effects.

Rehabilitation programs aim to improve functional outcomes and manage residual disabilities. Physical, occupational, and cognitive therapies are essential to prevent disuse injury and enhance recovery.

Prevention and Education

Drowning prevention is paramount and involves multiple layers of safety, as it is a global public health problem:

• Adult supervision

• Implementing safety measures such as barriers and water competency training

• Public awareness campaigns and the promotion of water safety practices

Patient Disposition and Transfer

The decision for patient disposition hinges on the injury history and associated conditions post-immersion. Patients experiencing mild symptoms from submersion injuries may require extended observation before discharge. Those with significant hypoxia necessitating intubation should be cared for in an intensive care unit, especially considering the potential for respiratory impairment from submersion immersion.

Severe hypothermic patients may need advanced interventions like cardiopulmonary bypass during transfer.

Consultations and Specialist Involvement

Patients with significant cervical spine injury or head trauma should be managed in a facility with sophisticated neurologic monitoring. Neurosurgery consultations are advisable for associated head or spine trauma, particularly in cases of brain injury and neck trauma.

Surgical consultations may be required for infections that develop after a drowning incident.
