Q & A
What is the main focus of the talk?
-The main focus of the talk is on practical advice and techniques for handling medical emergencies in the wilderness, specifically when resources are limited.
What is the significance of the case study presented in the talk?
-The case study of the helmeted mountain biker is used to illustrate the application of various wilderness first aid techniques and the importance of staying calm and assessing the situation before acting.
What is the first thing one should do when encountering a medical emergency in the wilderness?
-The first thing to do is to take a deep breath and stay calm, as effectiveness in handling the situation is compromised when one is anxious or adrenaline-fueled.
How can you assess the safety of the environment in a wilderness emergency?
-Assess the environment by considering the circumstances of the accident, such as whether it was caused by an avalanche, a fall from a cliff, or other factors, to ensure that no further victims are created while attempting a rescue.
What is the ABCDE mnemonic used for in wilderness first aid?
-The ABCDE mnemonic is a simple memory device used in emergency medicine to remember the order of actions to take when dealing with a patient in a bad situation: Airway (A), Breathing (B), Circulation (C), Disability (D), and Exposure (E).
What is the proper technique for clearing an obstructed airway according to the talk?
-The proper technique involves using the jaw thrust maneuver rather than the chin lift, especially in trauma cases, to pull the tongue off the back of the throat and open the airway.
How can you protect yourself from bloodborne diseases when attending to a bleeding wound?
-To protect yourself, you should wear gloves and possibly sunglasses or other eye protection to prevent contact with blood or body secretions.
What is the significance of the safety pin in a first aid kit?
-Safety pins are incredibly versatile in a first aid kit. They can be used for a variety of purposes, including holding a tongue forward in the mouth to prevent airway blockage, and are often considered an essential item in survival situations.
What are the steps to take when dealing with a patient who has a severe injury and has stopped breathing?
-When dealing with such a patient, you should first ensure your own safety and the safety of the environment. Then, you should open the airway, check for breathing and pulse, and if necessary, initiate CPR with chest compressions only, unless the patient is a child or has suffered a cold water drowning or lightning strike, in which case rescue breaths may also be given.
How can you determine if a patient has a tension pneumothorax?
-Signs of a tension pneumothorax include rapid respiratory rate, use of accessory muscles for breathing, and asymmetrical chest movement. One side of the chest may not move, and there may be a 'rice krispies' sensation or crepitus under the skin of the chest, indicating air has leaked from the lung cavity into the surrounding tissues.
Outlines
🌲 Wilderness Trauma and Emergency Response
The speaker discusses the importance of staying calm and focused during a wilderness emergency, emphasizing the practicality of their lecture on handling severe situations in the wild. They share a real-life case of a mountain biker with severe injuries, highlighting the need for quick assessment and action. The speaker stresses the importance of taking deep breaths to stay calm, surveying the situation for safety, and activating resources early. They also mention the importance of gloves to prevent disease transmission and the need to identify oneself to the injured person.
🚑 ABCDE Protocol and Airway Management
The speaker delves into the ABCDE protocol, starting with airway management (A), which is crucial for survival. They explain the importance of clearing the airway of obstructions and use the example of a biker with a blocked airway due to an accident. The speaker demonstrates techniques to open the airway, such as the jaw thrust, and discusses the use of a nasopharyngeal airway or improvised alternatives like a Camelback tube or safety pins to keep the airway clear. They also mention the need to assess the patient's breathing and look for signs of chest movement and crepitus, indicating a possible pneumothorax.
🏥 Advanced Wilderness Medical Techniques
The speaker continues with advanced wilderness medical techniques, discussing the management of a pneumothorax with a needle decompression, a procedure to relieve pressure in the chest cavity. They explain how to identify the signs of a tension pneumothorax and demonstrate the correct method to decompress the lung using an IV catheter. The speaker also addresses the management of an open pneumothorax or sucking chest wound, explaining how to cover the wound with a plastic bag and secure it with duct tape to allow air to escape while preventing further air from entering the chest cavity.
🩸 Controlling Bleeding and Assessing Circulation
The speaker discusses the next steps in the ABCDE protocol, focusing on circulation (C). They explain how to assess a person's circulation by looking at skin color, feeling for pulses, and performing the capillary refill test. The speaker emphasizes the importance of controlling bleeding, especially from scalp wounds, using direct pressure and, if necessary, tourniquets. They also discuss the use of improvised tourniquets and the importance of marking the time a tourniquet is applied. The speaker highlights the significance of recognizing signs of shock, such as paleness, coolness, and sweating, and the need to keep the injured person warm to prevent further complications.
🛡️ Disability Assessment and Neck Protection
The speaker moves on to discussing disability (D) in the ABCDE protocol, focusing on the assessment of the patient's neurological status. They explain how to check the level of consciousness, the ability to move limbs, and the importance of checking pupil response to light. The speaker demonstrates how to use pain stimuli to elicit a response when the patient is unresponsive. They also discuss the importance of neck protection for patients with potential spinal injuries, using a collar and side rolls to prevent movement. The speaker provides tips on improvising these items using available resources like aluminum splints, water bottles, and clothing.
🌡️ Exposure Management and Wound Care
The speaker addresses the 'E' in ABCDE, which stands for exposure, and its importance in preventing hypothermia in injured individuals. They discuss various methods to keep a patient warm, such as using a sleeping bag, garbage bags, and clothing. The speaker also covers wound care, emphasizing the need to clean wounds thoroughly with clean water and cautioning against closing wounds in the wilderness due to the risk of infection. They share techniques for controlling scalp bleeding, such as the hair tie technique and the use of superglue, and discuss the decision-making process regarding when to evacuate a patient based on the severity of their condition.
🚁 Evacuation Considerations and Essential First Aid Kit
The speaker concludes by discussing the challenges and considerations of evacuating injured individuals from wilderness settings, sharing a real-life example of a complex evacuation. They highlight the importance of recognizing when evacuation is necessary and the various factors that influence the decision. The speaker then presents their essential first aid kit items, emphasizing multi-use tools like duct tape, safety pins, garbage bags, and condoms. They also stress the importance of carrying over-the-counter medications like Benadryl and the inclusion of items like EpiPens for allergic reactions. The speaker encourages customization of first aid kits based on individual needs and the environment.
