Special Considerations
Orlowski J, Szpilman D. Drowning. In Centers for Disease Control and Prevention. A recent retrospective study of 247 patients who received ECLS following a drowning event suggests a 23.4% survival rate of patients placed on ECLS during cardiac arrest.11, Confusing language used by news outlets and spread on social media has led to misguided fear of complications weeks after exposure to water. While victims initially attempt to hold their breath and may reflexively swallow substantial quantities of water, relatively little aspiration of water occurs in the initial phase of a drowning. What is the Incidence and Significance of "Dry-Lungs" in Bodies Found in Water?

Two baseballs, each with a mass of $0.148 \mathrm{~kg}$, are separated by a distance of $395 \mathrm{~m}$ in outer space, far from any other objects. Clear the airway of obstructions, using a rigid suction catheter to remove any blood, vomitus, or secretions from the oropharynx. At these flow rates, inspired air will approach 100% oxygen, provided adequate seal is established. Szpilman D, Bierens J, Handley A, Orlowski J. Drowning. A variety of masks are available that can accept oxygen flow rates of 515 L/min. Subbarao, I. AMA Handbook of First Aid and Emergency Care, Random House Reference, 2009.

For the adequately perfusing drowning patient with spontaneous breathing, CPAP may accomplish the same thing. Securing the airway and assuring adequate ventilation are the first priorities in the resuscitation of any acutely ill or injured patient. Pathophysiology
This device is useful in resuscitation because of its ease of insertion and the low level of skill required to place it. In that era, the strategy was to expel water from the body by various methods, such as hanging the victim upside down or shaking them. His death was initially reported by news outlets as dry drowning. However, autopsy results showed that he died of myocarditis and not due to complications from swimming in shallow water. Place a bite block or dental prod before initiating intubation. The video laryngoscope, as its name implies, is a device with a video camera situated at the end of a curved blade that allows visualization of the anterior aspect of the hypopharynx and glottis. End-tidal carbon dioxide concentration during cardiopulmonary resuscitation. Rescuers should turn the victim on his/her side and clear the airway with fingers or cloth. Keep in mind that supraglottic airways, while convenient and effective short-term alternatives to endotracheal intubation, offer limited protection against further aspiration. Place your ear next to the person's mouth and nose. It may be impossible when the hypopharynx is filled with blood or secretions. At the most fundamental level, fatal drowning is death from asphyxia. Rescue, resuscitation, and reanimation. American Heart Association: "Hands-Only CPR simplifies saving lives for bystanders. 2009;163(3):203210. The Global Burden of Disease: 2004 Update. Archives of Emergency Medicine. All rights reserved. In 10% to 20% of drowning cases, the laryngeal spasm does not relax and no water enters. Ann Emerg Med 2002;40:30, Levitan R et al: Head-elevated laryngoscopy position: Improving laryngeal exposure during laryngoscopy by increasing head elevation. The ET can then be advanced over the endoscope into the trachea. About Us Our Team Annual Report Our Culture Contact Disclosures, ALiEMU ALiEM Cards Chief Resident Incubator Faculty Incubator Wellness Think Tank, ACEP Annals of Emergency Medicine EBSCO Health-DynaMed Plus Essentials of Emergency Medicine SAEM The Teaching CoOp US Acute Care Solutions Western Journal of Emergency Medicine. Drowning: Update 2009. 15. The root cause of death by drowning is fatal asphyxia, but due to a historically wide variance in terminology and definitions, environment (water temperature, cleanliness of the water, salt versus fresh water, submersion interval, and other comorbidities), the pathophysiology of the drowning process has been somewhat muddled. Make sure to always call 911 first before trying to rescue a victim and/or begin CPR. Human drowning subjects typically aspirate far less (2-4 mL/kg), and this amount is not believed to significantly alter body chemistry, at least in the resuscitation phase of management [5]. I-LMA, intubating laryngeal mask airway; LMA, laryngeal mask airway; PTTJV, percutaneous transtracheal jet ventilation; RSI, rapid sequence induction. Prevention of needless deaths from drowning. In the patient with respiratory compromise or arrest, but with adequate perfusion, oxygenation should be provided with 100% oxygen, and artificial ventilation should be performed if necessary. These can all result in cardiac arrest. If an ETC or King LT airway is in place, it may be used temporarily for continued resuscitation, but a premium should be placed in establishing a cuffed, endotracheal intubation. Let the chest rise completely between pushes. In one study of 598 autopsied drowning victims, 98.6% had water in their lungs [3]. Recommended guidelines for uniform reporting of data from drowning: the Utstein style. Circulation. Place the heel of one hand on the center of the chest at the nipple line.

Clinical signs associated with acute upper airway obstruction due to thermal injury include: The long term effects of a smoke inhalation injury are: Obstructive and restrictive lung disorders, What COHb level is associated with a throbbing headache, nausea, vomiting, and impaired judgement, Which of the following radiographic findings would be associated with the intermediate stage of recovery from a serious smoke inhalation injury, Which of the following would be recommended for the treatment of cyanide poisoning. Although there are no absolute contraindications to this technique, ambient lighting must be low to maximize its benefit. 11. Where indicated, spinal precautions must be maintained. 16. The laryngeal mask airway (LMA) is a device that has proven to be useful as an alternative for bagvalvemask ventilation and as a rescue option in the difficult airway. >> Learn the pathophysiology involved for drowning victims. Minerva Anestesiologica. EMS and the fire service should take a proactive strategy in drowning prevention by developing and implementing local prevention programs. Keep in mind that supraglottic airways, while convenient and effective short-term alternatives to endotracheal intubation, offer limited protection against further aspiration. Table 103. Wet drowning, dry drowning, and near-drowning are no longer accepted terms, although they may still be used when discussing drowning.
