what could compromise a drowning victims airway

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. This article was originally posted Mar. 2015;350:h418. American Heart Association: "Hands-Only CPR simplifies saving lives for bystanders. Tracheal placement results in a bright, well-circumscribed area of transillumination at the cricothyroid membrane. A pad beneath the occiput improves flexion of the neck. The LMA is a semirigid tube with a distal inflatable balloon mask that is inserted blindly into the hypopharynx. 2009;110(6):1,3901,401. Lunetta P, Modell JH, Sajantila A. 15. The cuffed oropharyngeal airway is a modified oropharyngeal airway with a large distal inflatable cuff. The mask lies over the larynx and seals around the glottic opening. Victims of near-drowning who receive chest compressions might vomit. Simultaneously, pulmonary aspiration occurs, typically at small volumes that do not obstruct airways but cause chemical changes. In the past, it was common to differentiate salt versus fresh water drownings based upon the premise that aspiration of hypertonic sea water could cause fluid shifts, electrolyte imbalances, and lysis of red blood cells. Bowman SM, Aitken ME, Robbins JM, et al. Granted, some drownings may be due to a cardiac event, but those cases are generally uncommon.9 Thus, its prudent to follow the airway, breathing and circulation (ABC) assessment model in drowning victims. Proactive prevention strategies include the following: Summary Initially, theres breath holding, and a small amount of water (typically less than 30 mL or 2 tablespoons) may enter the lungs if the patient gasps. All rights reserved. In fact, some have argued that attempts to resuscitate drowning victims led to the establishment of EMS and emergency medicine as we know it today.3 Interestingly, the face on the famous Resusci Anne manikin, developed by smund S. Laerdal, was based on a death mask from an unidentified girl who drowned in Paris, in the River Seine, in the 1880s.4, Despite a longtime human interest in drowning, however, the pathophysiology of the drowning process is still somewhat misunderstood by many. Suctioning the airway prior to the intubation attempt may improve the chance of a successful intubation using video laryngosopes. Masui. Make sure to always call 911 first before trying to rescue a victim and/or begin CPR. 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. However, weve learned a great deal about the pathophysiology of drowning during the past 40 years.5. Place a bite block or dental prod before initiating intubation. Retrieved Apr. Prolapse of the tongue and accumulation of secretions, blood, or vomitus are common causes of obstruction. The tube is inserted blindly and is fairly stiff, so that it usually enters the esophagus. Extraglottic devices can be used emergently, if no rapid sequence intubation (RSI) protocol exists or endotracheal intubation fails in the field. Masui. As stated, rescuers of near-drowning victims should always ensure their own safety before attempting any rescue, especially an in-water rescue. Blind intubation with a lighted stylet is most suitable for deeply comatose or apneic patients when there is little risk of stimulating protective reflexes or biting of the intubators hand. 7. In the typical medical cardiac arrest, the patient has suffered a cardiovascular event (e.g., heart attack, stroke or arrhythmia). It is inserted like a traditional oral airway, and the cuff is then inflated in the supraglottic space. Alternatively, place several layers of gauze between the intubators hand and the patients teeth. We aim to disrupt how medical providers and trainees can gain public access to high-quality, educational content while also engaging in a dialogue about best-practices in EM and medical education. Even if a near-drowning victim has been submerged for a long period, CPR may still be effective especially in cases where the water is cold. 2001;48(3):627646. (2009). Esophageal placement causes little or no transillumination. (2013). These can all result in cardiac arrest. Marinozzi S, Bertazzoni G, Gazzaniga V. (2012). &\begin{array}{llllllll} Thygerson, A. American College of Emergency Physicians First Aid and CPR Essentials, Jones and Bartlett Publishers, 2007. This method can be used when blood, secretions, or vomitus fill the hypopharynx. The most important thing to remember is that for anyone who is unresponsive and isnt breathing, CPR needs to be started immediately. Drowning cases peak this time of year and represent a leading cause of mortality in children. Because of reports of esophageal trauma, some authors recommend Gastrografin swallow or endoscopy after use of an esophageal obturator airway (EOA)-like device. Contact with fresh water, relatively hypotonic to plasma, results in disruption of alveolar surfactant, while hypertonic salt water creates an osmotic gradient that draws fluid into alveoli, diluting and washing out surfactant. However, this premise was based upon canine studies in which the test animals typically aspirated a great deal of water, roughly 20 mL/kg. Keep in mind that supraglottic airways, while convenient and effective short-term alternatives to endotracheal intubation, offer limited protection against further aspiration. When the epiglottis is reached, use a scooping or ladling motion to place the tip into the glottis. While some sources note that analyzing the slope of the alveolar plateau (Phase III) can be useful for detecting significant ventilation/perfusion (VQ) mismatch from increased dead space ventilation or intrapulmonary shunt both of which may be present in drowning patients this is only true of volumetric capnography, a technology not commonly found in prehospital monitor/defibrillators [6]. Remember that the inflammatory cascade triggered by aspirated water contacting pneumocytes may require positive-end expiratory pressure to recruit and retain patent alveoli. \mathrm{B} & - & - & - & + & - & + \\ Although this procedure can be carried out without movement of the C-spine, it requires skill and practice. Its important to understand the differences in treatment priorities in drowning when compared with standard emergency medical care. Look for a box or option labeled Home Page (Internet Explorer, Firefox, Safari) or On Startup (Chrome). Recommended guidelines for uniform reporting of data from drowning: the Utstein style. Circulation. Szpilman D. Near-drowning and drowning classification: a proposal to stratify mortality based on the analysis of 1,831 cases. The study authors noted that active ventilation is required to aspirate water into the lungs; water does not flow passively into the lungs of drowning victims. In the drowning sequence, laryngeal spasm occurs by water entering the upper airways. Table 102. Otherwise, approach the patient from the right shoulder. The majority of patients are not resuscitated and those who survive usually suffer profound neurological impairment. References The primary goal in the management and resuscitation of the drowning victim is to reverse the hypoxic insult. To delineate the incident's outcome, this is further divided into descriptive terms such as death, morbidity, and no morbidity. Humans have always been both intrigued by and fearful of drowning. (See Figure 101.). This may be called Tools or use an icon like the cog. This position cannot be used when there is cervical spine injury. Patients who require bag-assisted ventilation should generally be intubated as soon as it can be accomplished safely and practically. The terms dry drowning, secondary drowning, and near drowning are used to describe a variety of events. In general, however, it is not recommended for prolonged ventilation owing to gastric dilatation and technical difficulty. As in all conditions, the primary assessment is key to treatment. Part 10.3: Drowning. The patient may be approached from the head if laryngoscopy is used. Occasionally it may be the only form of ventilation available in an apneic patient when an airway cannot be secured. 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. Place the heel of one hand on the center of the chest at the nipple line. Outcomes reporting for drowning was classified as death, morbidityor no morbidity; other non-standard terminology such as dry drowning, wet drowning, near drowning, active or passive drowningor delayed drowning are discarded. The self-filling bag permits use with spontaneously breathing patients. Is CPR performed any differently for victims of drowning? is a question our instructors often field during CPR classes at CPR Seattle. Blind intubation techniques, video laryngoscopy, fiberoptically assisted intubations, and surgical airways are all options in the difficult airway that cannot be intubated by direct means. Key resuscitation considerations include: ALiEM is your digital connection to the cooperative world of EM. Caution should be exercised because this time interval can be significantly shortened in an ill patient. The intubating LMA (I-LMA) is a modification of the LMA that has been developed to act as a conduit to allow blind passage of the ET through the glottis.

Resuscitation. 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. The mouth-to-mask technique is another method of providing positive pressure ventilation. What is the Incidence and Significance of Dry-Lungs in Bodies Found in Water? Retrieved Apr. Of course, if cardiac arrest is present, CPR should be initiated and necessary ALS measures provided. For every child that dies from accidental drowning, another five are treated in the ED for non-fatal injuries. Archives of Emergency Medicine. The World Congress on Drowning met again in November 2015, but findings from that meeting have yet to be promulgated. Lexipol. Even strong swimmers can find it difficult to swim with an unconscious person. Oehmichen M, Hennig R, Meissner C. Near-drowning and clinical laboratory changes. Among children ages 14 years old, most drownings occur in residential swimming pools. 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. At these flow rates, inspired air will approach 100% oxygen, provided adequate seal is established. In drowning victims in cardiac arrest, waveform capnography can reliably confirm tube placement, gauge effectiveness of chest compressions, detect migration or displacement of advanced airway devicesand detect return of spontaneous circulation [7]. Rescuers must also keep themselves safe during any rescue attempt. Contrary to popular culture, abdominal thrusts are not indicated. 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]. Volume, rather than composition, determines pulmonary derangement. Drowning is a process causing respiratory insufficiency from submersion or immersion in a liquid medium, which may or may not result in the victim's death. Unconsciousness typically occurs within four to six minutes of submersion. 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). 8. For a baby, be careful not to tilt the head back too far. Recommended guidelines for uniform reporting of data from drowning: the Utstein style. 13. 2005 - 2023 WebMD LLC. Drowning is the second leading cause of unintentional pediatric deaths in the United . Emerg Med 2002;22:31, Shuster M et al: Airway and ventilation management. Suppose the mass of the balls is doubled and the balls are released from rest, what speed do they have when their separation has decreased to $145 \mathrm{~m}$ ? Wet drowning, dry drowning, and near-drowning are no longer accepted terms, although they may still be used when discussing drowning. The LMA is appropriate for use in adults and pediatrics, including neonates weighing more than 2 kg. Arch Pediatr Adolesc Med. The King LT airway is a single-lumen tube with two cuffs, but both are inflated simultaneously at a solitary site instead of the two required on an ETC. Evaluate the effectiveness of the patients respiratory effort. Backward, upward, rightward pressure (also known as the BURP maneuver) on the external larynx by an assistant to the intubator has been used with some success to increase the intubators view of the glottic opening. The primary goal in the management and resuscitation of the drowning victim is to reverse the hypoxic insult. These pulmonary secretions also necessitate vigilant monitoring of capnograph waveforms, and frequent replacement of sidestream capnograph adapter and tubing if it becomes occluded. These statistics covered 92 cases. Although theres some injury to the lungs during the drowning process, the final common pathway of all morbidity and mortality is hypoxia with resultant anoxic brain injury. This especially applies to BLS-trained EMS professionals, but is advised for all rescuers. Legal Medicine (Tokyo). Securing the airway and assuring adequate ventilation are the first priorities in the resuscitation of any acutely ill or injured patient. Most young children who drowned in pools were last seen in the home, had been out of sight less than five minutes and were in the care of one or both parents at the time. Remember that the inflammatory cascade triggered by aspirated water contacting pneumocytes may require positive-end expiratory pressure to recruit and retain patent alveoli. Rescuers should turn the victim on his/her side and clear the airway with fingers or cloth. Masks equipped with reservoirs and non-rebreathing valves can deliver oxygen concentrations close to 100% at flow rates of 10 L/min if an adequate seal can be maintained between the mask and face. JEMS. Water is also toxic to pneumocytes, the cells that make up alveoli. 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). finds relevant news, identifies important training information, Falk JL, Rackow EC, Weil MH. Cico SJ, Quan L. Drowning. \end{array} Tilt head back and lift the chin. A head-elevated laryngoscopy position has also been found to be successful in increasing the view of the glottic opening. Despite the presence of non-sterile water, salt or chlorine, the lungs typically recover, and emergency treatment should therefore be directed at interrupting the drowning process by providing oxygenation and ventilation as quickly as possible. Cushing TA, Hawkins SC, Sempsrott J, et al: Wilderness Medicine Sixth edition. 2008;10(1):15. Prevention Many emergency physicians now preferentially turn to one of these airway management tools when managing difficult airway patients. Brenner RA, Taneja GS, Haynie DL, et al. The water that enters the lungs, regardless of the type, can wash away surfactant, leading to atelectasis (collapse of the alveoli). Classes are available through the American Red Cross, local hospitals, and other organizations. In patients with unprotected airways, cricoid pressure (the Sellick maneuver) is recommended (Figure 104). cervical spine fracture) when evaluating a drowning case, less than 0.5% of drownings are traumatic. In patients with intact airway reflexes, placement of either device may cause emesis, gagging, or laryngospasm. Unintentional Drowning: Get the Facts. Laerdal Medical. When direct visualization is difficult (Table 104), various methods are available to improve visualization of the glottic opening. While some sources note that analyzing the slope of the alveolar plateau (Phase III) can be useful for detecting significant ventilation/perfusion (VQ) mismatch from increased dead space ventilation or intrapulmonary shunt both of which may be present in drowning patients this is only true of volumetric capnography, a technology not commonly found in prehospital monitor/defibrillators [6]. 2003;108(20):2,5652,574. What is the Incidence and Significance of "Dry-Lungs" in Bodies Found in Water? Strategies may include force air, radiant heat, and heat packs. 4. Oehmichen M, Hennig R, Meissner C. Near-Drowning and Clinical Laboratory Changes. Supplemental oxygen is provided via a port in the mask or via a nasal cannula worn by the operator. Do not terminate resuscitation prematurely. Retrieved February 16, 2016, from http://www.cdc.gov/injury/images/lc-charts/leading_causes_of_injury_deaths_highlighting_unintentional_injury_2013-a.gif. In contrast, an adult will struggle for approximately 60 seconds before they become submerged. Bronchoconstriction, edemaand varying degrees of atelectasis and pulmonary shunting usually follow. 1991 Jul;40(7):1048-51. Where indicated, spinal precautions must be maintained. During and after placement, head position should be maintained to optimize airway patency. Turn the head back to the center. British Medical Journal. Elsevier: Philadelphia, 2012. History 19. Although providers are typically taught to be aware of possible trauma (e.g. Many circumstances of anatomic variation, facial hair, or maxillofacial trauma make a tight seal impossible. If not, ask someone to call 911. The LMA does not protect against aspiration. Obesity may diminish the intensity of transillumination. Centers for Disease Control and Prevention. Steedman DJ, Robertson CE. Garner A, Barker C, Weatherall A. Retrospective evaluation of prehospital triage, presentation, interventions and outcome in paediatric drowning managed by a physician staffed helicopter emergency medical service. Water is also toxic to pneumocytes, the cells that make up alveoli. A ten-year Australian study showed that for the victims who received compressions, 86% vomited. As for other blind techniques, avoid this method when direct laryngoscopy can be performed. You must enable JavaScript in your browser to view and post comments. Inhaled water causes loss of surfactant, alveolar collapse, noncardiogenic edema, intrapulmonary shunting, and VQ mismatch.9 Patients often require immediate positive pressure ventilation with high FiO2. Traumatic Cardiac Arrest (TCA): Maybe We Could Do Better? The DobzhanskyMuller model suggests that divergence among alleles at different gene loci leads to genetic incompatibility between species. Those few victims found without significant amounts of water in their lungs were believed to be dead, and thus without respiratory effort, when they went into the water. This means that water will enter into the stomach rather than the lungs. South Med J. The airway should be assessed for patency and breathing adequacy, and lung sounds should be assessed for crackles. 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. 2010;103(7):650653. You can follow him on Twitter (@AmboDriver),Facebook, LinkedIn, or email him at kelly@ambulancedriverfiles.com. trauma to the airway from an accident. Prevalence of traumatic injuries in drowning and near drowning in children and adolescents. A ventilation port exists between the oropharyngeal and esophageal cuffs that provides ventilation toward the larynx. The end result is disruption of alveolar capillary membranes, damage to the alveolar basement membraneand inflammation of pneumocytes. The former is preferred in pediatric patients as to prevent trauma to the soft palate. Kelly Grayson, NRP, CCP. Save my name, email, and website in this browser for the next time I comment. In the past, it was common to differentiate salt versus fresh water drownings based upon the premise that aspiration of hypertonic sea water could cause fluid shifts, electrolyte imbalances, and lysis of red blood cells. Because of this, strategies were devised in the 17th century to try and resuscitate victims of drowning. Measurement of End-tidal Carbon Dioxide Concentration During Cardiopulmonary Resuscitation. A GCS, rectal temperature, blood glucose level, and brief trauma survey should be included in the initial evaluation. Idris AH, Berg RA, Bierens J, et al. Care must be taken not to push the tongue backward into the pharynx, worsening the obstruction. Following airway opening, positive pressure ventilation may be used to preoxygenate a patient before intubation. Water regardless of type entering the lungs disrupts surfactant, resulting in atelectasis, pulmonary shuntingand significant ventilation/perfusion (V/Q) mismatch.
