BREAKING NEWS — The American Red Cross and American Heart Association today announced changes to guidelines for administering first aid. Among the most noteworthy revisions are new and updated recommendations for the treatment of bleeding; recognition of stroke; recovery position; anaphylaxis (severe allergic reaction); use of aspirin with heart attacks; and treatment of hypoglycemia (low blood sugar) in diabetics. 

Every 5 years, the science and practices related to First Aid, CPR and Emergency Cardiovascular Care are reviewed and new recommendations related to providing care are published. As a result, organizations such as the American Red Cross revise their training programs to incorporate new protocols and practices for how to administer care and apply lifesaving skills. This process is often referred to as ECC. Experts analyzed the science behind each question and worked to reach consensus on related treatment recommendations with the goal of reducing morbidity and mortality due to emergency events. Last updated in 2010, these recommendations form the recognized scientific basis for most first aid training around the world.

BLEEDING CONTROL
The revised guidelines stress the importance of stopping severe bleeding as a critical first aid skill. Almost all bleeding can be controlled by steady, well-aimed direct pressure, with or without a gauze or cloth dressing over the wound. The guidelines recommend pressing hard and holding steady pressure for at least five minutes without lifting dressings to see if the bleeding has stopped. While direct pressure is still the first line of defense, the guidelines acknowledge the important role tourniquets and hemostatic agents play in stopping life-threatening bleeding when standard measures fail or are not possible. Tools now available and recommended to first aid providers include tourniquets for severe bleeding on a leg or arm. For open wounds not on an extremity, the guidelines suggest use of a hemostatic dressing, which is coated with a special agent to enhance clotting and help stop bleeding when correctly applied and combined with direct pressure. Hemostatic dressings are readily available online and at pharmacies.


HYPOGLYCEMIA TREATMENT
Early treatment of hypoglycemia (low blood sugar) while the patient is still conscious and still able to follow instructions can prevent progression to more serious hypoglycemia that would require more advanced treatment. To avoid lay responders from giving too much or too little sugar, the new guidelines recommend use of glucose tablets purchased at a retail pharmacy. Glucose tablets have been shown to be more effective at resolving symptoms of hypoglycemia than dietary forms of sugar. If glucose tablets are not available, food sources such as sucrose candies, dried fruit, or orange juice can still be used.


RECOVERY (& HAINES) POSITION
If the person is unresponsive and breathing normally, without any suspected spine, hip or pelvis injury, turn the victim to a lateral side-lying position. Studies show some respiratory improvement in this position compared to a supine, or face up, position. In addition to the change from the supine position, the modified HAINES position is no longer recommended due to lack of scientific evidence.


ANAPHYLAXIS
Under the revised guidelines for treating anaphylaxis (severe allergic reaction), if symptoms persist beyond the initial dose and arrival of advanced care will exceed 5-10 minutes, the first aid provider may give a second epinephrine injection from a prescribed auto-injector.


STROKE RECOGNITION
Approximately 800,000 Americans have a stroke each year, leaving them at risk for long-term disability. Early recognition of stroke through the use of a stroke assessment system decreases the interval between the time that the incident occurs and the time it takes for that person to arrive at a hospital and receive specific treatment. This faster time to treatment may reduce the damage and disability from a stroke. This is the first time that the guidelines have examined the science behind inclusion of a stroke identification system into all first aid courses.


THE USE OF ASPIRIN FOR HEART ATTACKS
The updated guidelines clarify that aspirin should be used when helping someone suspected of having a heart attack, characterized by symptoms such as chest pain accompanied by nausea, sweating and pain in the arm and back. If the first aid provider is unclear on whether this is a heart attack or simply someone experiencing non-cardiac related chest pain or discomfort, then aspirin should not be given. Additionally, the updated guidelines emphasize that there is no need to distinguish between enteric versus non-enteric coated aspirin as long as the aspirin is chewed and swallowed.

CHEST COMPRESSIONS
The updated guidelines place upper limits on both the rate and depth of compressions to better improve outcomes.  Chest compressions should continue to be provided for victims of cardiac arrest of any age.  Compressions should now be delivered at a range of 100-120 per minute as evidence suggests that rates above this upper limit may lead to poor outcomes. In addition, an upper limit to the depth for compressions has also been recommended.

For adults and adolescents who have reached puberty, continue to compress the chest at least 2 inches, but try to avoid compressing the chest greater than 2.4 inches to minimize complications. The depth of compressions for infants and children remain that same at about 1½ inches for infants and about 2 inches for children. Both rate and depth of compressions are difficult to judge and the use of feedback devices, if available, may be beneficial.


INTERRUPTIONS OF CHEST COMPRESSIONS

Minimizing interruptions of chest compressions are a critical focus of the CPR guidelines. All responders should limit any interruptions of chest compressions, such as providing ventilations or performing other critical tasks, to less than 10 seconds. Responders should focus on maintaining as high a chest compression fraction (CCF) time as possible during resuscitation. CCF is the proportion of time that chest compressions are being performed during the duration of the arrest as compared to any pauses such as the time to deliver ventilations or apply the AED.  A CCF of at least 60% is desired, with a goal of achieving a CCF of 80% to maximize survival is recommended.
