2006 Jun;72(6):577-85. Szpilman D, Bierens J, Handley A, Orlowski J. Drowning. For every child that dies from accidental drowning, another five are treated in the ED for non-fatal injuries. In Centers for Disease Control and Prevention. If the glottis is truly not visible after using these basic techniques, then other options are available. All rights reserved. Resuscitation. These methods will be discussed in the next section. vocal cord issues. Blind finger sweep is contraindicated. - Perform CPR if necessary (if they are not breathing normally) Call for emergency medical help, even if the victim appears to recover . In contrast, the drowning victim has suffered a hypoxic event (similar to most pediatric cardiac arrests). The bodys natural response is, "OK, if I can drink the lake first, then Ill be able to breathe." Son K, Hwang S, Choi H. Clinical features and prognostic factors in drowning children: a regional experience. Youn CS, Choi SP, Yim HW, et al. 2008;10(1):15. The Global Burden of Disease: 2004 Update. 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. Because of operational difficulties and risks of aspiration, the bagvalvemask is a temporizing measure under most circumstances. It can be performed either orally or nasally and oxygen can be insufflated during the procedure. Important basic airway devices to relieve upper airway obstruction from collapsed pharyngeal tissues. The I-LMA has a metal handle attached to it that allows the user to stand at the head of a patient and manipulate it similarly to using laryngoscope handle in order to reposition the device and tube as needed. 4. Securing the airway and assuring adequate ventilation are the first priorities in the resuscitation of any acutely ill or injured patient. As time submerged increases, hypoxia and hypercarbia set in, the brainstem triggers involuntary breathing, and water enters the lungs whether there was a brief interval of laryngospasm or not. Usually at least the face and airway are immersed for drowning to occur. This device is useful in resuscitation because of its ease of insertion and the low level of skill required to place it. Advanced airway management, if it can be performed quickly by expert rescuers, should be performed if indicated. As the common pathophysiology in all types of drowning death is profound hypoxic insult, oxygenation and ventilation are the most effective tools in managing the drowning patient. Let the chest rise completely between pushes. 2006 Jun;72(6):577-85. The amount that actually enters the lungs in human drowning is significantly less than this (24 mL/kg).7 Thus, all drowning patients are initially treated the same (with the rare exception of drowning in industrial chemicals or sewage). Clear and position the airway as described above. Because of the amount of water aspirated by most drowning patients, pulmonary secretions may be a concern, and frequent suctioning may be required. These patients are at high risk of regurgitation and further aspiration.9, Patients who suffer a submersion event may become hypothermic even in hot weather. Out-of-hospital cardiac arrest due to drowning: An Utstein Style report of 10 years of experience from St. Marys Hospital. \mathrm{E} & + & - & - & + & - & - This method may be easier for a single operator, because both hands can be used to seat the mask. For every child that dies from accidental drowning, another five are treated in the ED for non-fatal injuries. During bagvalvemask ventilation, proper head position must be maintained to preserve airway patency. Key principles of management are maintaining adequate oxygenation, preventing aspiration and stabilising body temperature. This article was originally posted Mar. Many circumstances of anatomic variation, facial hair, or maxillofacial trauma make a tight seal impossible. Drowning cases peak this time of year and represent a leading cause of mortality in children. Due to the conditions associated with near-drowning, the AHA advises rescuers to deliver two rescue breaths first, and then begin the cycles of compressions and breaths as directed. Lubricate the tube with anesthetic jelly before insertion. Alternatively, the King LT airway is now becoming a popular device due to its ease of use and rapid deployment. Spontaneously breathing children should initially be placed in the lateral decubitus (recovery) position. I-LMA, intubating laryngeal mask airway; LMA, laryngeal mask airway; PTTJV, percutaneous transtracheal jet ventilation; RSI, rapid sequence induction. This maneuver requires the intubator to use a bimanual technique for intubation. 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. Salomez F, Vincent J. Drowning: a review of epidemiology, pathophysiology, treatment and prevention. How much do I need to know about ECGs to pass ACLS. In addition, aspirated fluid produces vagally-mediated vasoconstriction and pulmonary hypertension. Confirm the tube position by end-tidal CO2 detector and chest x-ray. Withdraw the tube 12 cm and auscultate again. An old technique that has resurfaced for use in the last few years, called external laryngeal manipulation (ELM), is probably even more successful at obtaining a better look at the glottis. The bagvalvemask unit is the device most commonly used to provide positive pressure ventilation in the emergency department. Blanch L, Romero PV, Lucangelo U. Volumetric Capnography in the Mechanically Ventilated Patient. Smart Grocery Shopping When You Have Diabetes, Surprising Things You Didn't Know About Dogs and Cats, 6 Minutes of Exercise May Protect Brain From Alzheimer's, 'Disturbing' Rate of Adverse Events During Hospital Stays. Table 102. (2013). If the C-spine is not injured, place the head in the sniffing position with the chin lift maneuver to open the airway (Figure 102). Use waveform capnography to guide patient ventilation. Bronchoconstriction, edemaand varying degrees of atelectasis and pulmonary shunting usually follow. Now that the pathophysiology of drowning is better understood, terminology related to drowning has been standardized. Its important to understand the differences in treatment priorities in drowning when compared with standard emergency medical care. A clear mask is recommended to identify emesis. The process of drowning begins when the victims airway is submerged below the surface of the water. Thus, the 2010 American Heart Association Guidelines for circulation, airway, breathing (CAB) should be modified for drowning victims. Make sure not to press on the ribs or the end of the breastbone. Trends in U.S. pediatric drowning hospitalizations, 19932008. American Heart Association: "Hands-Only CPR simplifies saving lives for bystanders. The mouth-to-mask technique is another method of providing positive pressure ventilation. Unconsciousness typically occurs within four to six minutes of submersion. Remember that the inflammatory cascade triggered by aspirated water contacting pneumocytes may require positive-end expiratory pressure to recruit and retain patent alveoli.

Aside from the lighted stylet, no special equipment is required. Unintentional Drowning: Get the Facts. Therefore there is usually no need to clear the airway of water, as only a small amount is aspirated, and that which is aspirated will normally be absorbed into the bloodstream. Vomiting is common in drowning victims and aspiration of gastric contents is a major complication. 1. As in all conditions, the primary assessment is key to treatment. cervical spine fracture) when evaluating a drowning case, less than 0.5% of drownings are traumatic. The most important and detrimental consequence of submersion is hypoxia. In salt water, osmosis pulls water out of the bloodstream and into the lungs, making the blood thicker and taxing the heart. The primary goal in the management and resuscitation of the drowning victim is to reverse the hypoxic insult. Drowning can further be classified as warm-water (>20 C) or cold-water (<20 C). Kelly Grayson, NRP, CCP. 19. 14. Copyright 2023 EMS1. What could cause dry lungs in this near drowning? Archives of Emergency Medicine. These pulmonary secretions also necessitate vigilant monitoring of capnograph waveforms, and frequent replacement of sidestream capnograph adapter and tubing if it becomes occluded. Drowning can present with severe respiratory failure as well as hypothermia. In addition, the equipment is expensive and easily damaged. Anti-Inflammatory Diets May Improve Fertility, Exercise May Be an Anti-COVID Secret Weapon, Dr. Whyte's Book: Take Control of Your Diabetes Risk, Street Medicine Reaches People Where They Live, Health News and Information, Delivered to Your Inbox, 4. The suction device should be set at 120 mm Hg. Victims of near-drowning who receive chest compressions might vomit. The soft, rubber, noncuffed nasopharyngeal tube tends to be better tolerated in a semiobtunded patient. The ETC has found favor in prehospital and emergency department settings. Steedman DJ, Robertson CE. Historically, this was known as a wet drowning. Without a patent airway and adequate gas exchange, other resuscitative measures will usually be futile. Press down at least 2 inches. There is a common misconception that cold water drowning is associated with better outcomes. All of the following are evaluated during a polysomnographic sleep study EXCEPT: Continuous positive airway pressure (CPAP) is useful in the management of the patient with obstructive sleep apnea because it: A CPAP titration polysomnogram is performed to: find the CPAP level to maintain an open airway. \hline 1 & 2 & 3 & 4 & 5 & 6 \\ breathing in a large amount of smoke from a fire. Epistaxis may occur during insertion, and suction should be available. 1996 Aug;12(4):245-8. A ventilation port exists between the oropharyngeal and esophageal cuffs that provides ventilation toward the larynx. ER chief resident at the George Washington University, Bridge to EM: Senior Medical Student Curriculum, GroundED in EM: A Third-Year Student Curriculum. JEMS. However, weve learned a great deal about the pathophysiology of drowning during the past 40 years.5. 20. Suction equipment must be available. Modell JH. Part 10.3: Drowning. Elsevier: Philadelphia, 2012. These pulmonary secretions also necessitate vigilant monitoring of capnograph waveforms, and frequent replacement of sidestream capnograph adapter and tubing if it becomes occluded. Gathering together the latest research, news, videos, and training, CapnoAcademy is the ultimate resource for EMS professionals interested in learning more about all things Capno related. Ultimately, this desire to save drowning victims became the model for subsequent first-aid care and education. If the patient is alert, inform him or her of your plan. Prolapse of the tongue and accumulation of secretions, blood, or vomitus are common causes of obstruction. Patients who require bag-assisted ventilation should generally be intubated as soon as it can be accomplished safely and practically. Laosee OC, Gilchrist J, Rudd R. Drowning 2005-2009. Szpilman D. Near-drowning and drowning classification: a proposal to stratify mortality based on the analysis of 1,831 cases. https://journals.lww.com/em-news/Fulltext/2017/08000/News___Drowning__in_a_Sea_of_Misinformation.3.aspx, https://journals.lww.com/em-news/Fulltext/2018/06000/Special_Report__The_Myth_of_Dry_Drowning_Remains.3.aspx, Accidental Hypothermia and Cardiac Arrest: Physiology, Protocol Deviations, and ECMO, Resuscitation of a Drowning Victim: A Literature Review, Free Comprehensive Curriculum: Climate Change and Emergency Medicine, Trick of the Trade: A Fiberbougie through a supraglottic airway device (King tube), PECARN Pediatric Head Trauma: Official Visual Decision Aid, A Starters Roadmap to EM Resources: Books, Websites, and Apps, D50 vs D10 for Severe Hypoglycemia in the Emergency Department, The Dirty Epi Drip: IV Epinephrine When You Need It, Tips for Interpreting the CSF Opening Pressure, Trick of the Trade: Mix Ceftriaxone IM with Lidocaine for Less Pain, Trick of the Trade: Urine Pregnancy Test Without Urine, Wellness and Resiliency during Residency: EM is a career with unresolved stories, Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported License, Academic Life in Emergency Medicine - All Rights Reserved (except for the PV Cards and MEdIC Series PDFs), Active rewarming to goal of at least 34C. Masui. Szpilman D, Bierens JJ, Handley AJ, et al. Kelly Grayson, NRP, CCP, is a critical care paramedic in Louisiana. While following ACLS algorithms, drowning resuscitation should therefore focus on reversing respiratory failure and hypothermia. Still, an all-too-common event, the morbidity and mortality of drowning can be mitigated by prevention, recognition and target treatment. As such, conventional CPR techniques with artificial ventilation should be performed, rather than cardiocerebral resuscitation techniques utilizing passive oxygenation. This device has been demonstrated to be easy to insert with limited prior training. Crit Care Clin 2000;16:429, Levitan RM et al: Airway management and direct laryngoscopyA review and update. At these flow rates, inspired air will approach 100% oxygen, provided adequate seal is established. It may be impossible when the hypopharynx is filled with blood or secretions. You can follow him on Twitter (@AmboDriver),Facebook, LinkedIn, or email him at [email protected]. One caveat applies in using capnography in drowning patients. For the adequately perfusing drowning patient with spontaneous breathing, CPAP may accomplish the same thing. One caveat applies in using capnography in drowning patients. Helpful signs include respiratory rate, tidal volume, accessory muscle use, level of consciousness, skin color, upper airway sounds, and auscultated lung sounds. Lyster T, Jorgenson D, Morgan C. The safe use of automated external defibrillators in a wet environment. Minerva Anestesiologica. While above the water, a child will typically struggle for only 20 seconds before they become submerged. The victim will likely have swallowed a good deal of water in addition to whatever amount may have entered the lungs. Signs may include wheezing, sonorous respirations, stridor, cough, and dysphonia.
