Air Med J. Performing emergency endotracheal intubation necessarily means doing so under less than ideal conditions. If tracheal intubation is impossible, or the laryngeal inlet cannot be seen, the safest options are (1) passage of an orotracheal tube over a fiberoptic laryngoscope and (2) needle or surgical cricothyroidotomy in a child older than 12 years and needle cricothyroidotomy in a child younger than 12 years. None of us are too small to make an impact. Just the Facts. Intubation is a common procedure doctors use during surgery or in a medical emergency to help a person breathe. The choice of intubation technique depends on the severity of . (C-1) 2-1.29 Define, identify and describe a tracheostomy, stoma, and tracheostomy tube. INTUBATION TECHNIQUES. Some factors associated with improved success are predictable and can be modified to improve outcome. These more advanced techniques include the use of SGAs, endotracheal intubation (ETI), or cricothyrotomy. The patient's 12-lead EKG identifies St-segment elevation MI, and the patient is being prepped for transport to the cath lab to undergo coronary reperfusion therapy. You are […] One approach is paramedic rapid sequence intubation (RSI), which may improve outcomes in adult patients with traumatic brain injury. assisted ventilations or intubation. Endotracheal intubation in the out-of-hospital setting. RSI should not be used routinely and should be implemented only when the patient cannot be intubated because of clenched jaw, persistent seizures . Only prehospital ROSC suggested an advantage to standard endotracheal intubation (10.6% vs 6.4%; OR 1.04, 95% CI 1.02-1.07), according to Wen-Chu Chiang, MD, PhD, of National Taiwan University . Endotracheal Intubation •Advantages -Secure airway -Protection against aspiration -Alternative to IV or IO route . Field intubation is the placement of an advanced airway or endotracheal tube (ET) by emergency medical services (EMS) personnel outside the hospital setting. Of these, 2 articles were identified as having been conducted in the ED. There may be time to call for help from anesthesia and ENT. During all advanced airway management procedures, the patient should be monitored adequately. In addition to difficulties arising from physical or anatomical abnormalities, airway management can be made "situationally difficult" in the prehospital environment in ways that are not seen in the hospital setting due to factors like patient positioning . However, many patients present to emergency medical services with coma of non . Despite the controversy regarding the need for intubation in the out-of-hospital environment, most experienced prehospital practitioners can relate a situation where basic procedures were insufficient to preserve the patient's airway patency. 17,24,27. and cardiac-arrest situations. Introduction Pre-hospital intubation by paramedics is widely used in comatose patients prior to transportation to hospital, but the optimal technique for intubation is uncertain. Specifically, this review will focus on comparing the benefit and harms across three different airway management approaches: bag valve mask (BVM . In the traumatic head injury group, some studies demonstrate an advantage to prehospital intubation but many studies do not as well. Studies comparing outcomes of out-of-hospital cardiac arrest in adults treated by either emergency medical technicians or paramedics failed to show a link between long-term survival rates and paramedic skills such as intubation, intravenous cannulation, and drug administration. Supraglottic airway devices may be utilized as a backup in the case of unsuccessful endotracheal intubation at one service, or be the primary advanced airway option at another. Retrospective observational cohort study in an anaesthesiologist-staffed HEMS in Switzerland. 4. Knowing these advantages, it seems a no-brainer to choose endotracheal intubation for your patient. It is one of the first ventilator parameters set and would typically be "dialed in" to between 3 and 5 cmH 2 O, sometimes referred to as, "physiologic PEEP." 4 This positive, end expiratory, pressure serves to prevent collapse of . Significant airway complications (such as hypoxia or pulmonary aspiration) occurred in 106 of these 170 patients (62%). 2. It is safe, simple, and can be performed quickly in emergency situations. In the early years of out-of-hospital emergency medical services (EMS) systems, advanced life support personnel were not only trained in the nuances of how to avoid overzealous ventilation and properly place an endotracheal tube in very challenging circumstances, but they were also well-supervised on-scene by expert physicians who . 2-1.28 Describe the use, advantages and disadvantages of an oxygen humidifier. Emergency airway placement by EMS providers: Comparison between the King LT supralaryngeal airway and endotracheal intubation. (C-1) 2-1.30 Explain the risk of infection to EMS providers associated with ventilation. Which is an advantage of EMS transport to a stroke hospital for a patient with a suspected acute ischemic stroke? Is intubation life support? Pre-hospital basic airway interventions can be ineffective at providing adequate oxygenation and ventilation in some severely ill or injured patients, and advanced airway interventions are then required. Rapid sequence intubation mandates being familiar with a variety of sedative as well as at least one or two paralytic agents. ETI with the use of neuromuscular blockade is known as rapid-sequence intubation (RSI). CONTEXT: Endotracheal intubation (ETI) is widely used for airway management of children in the out-of-hospital setting, despite a lack of controlled trials demonstrating a positive effect on survival or neurological outcome. We also wanted During the post-cardiac arrest care phase, your team has optimized the patient's oxygenation, ventilation, and hemodynamic status. Abstract Objective The primary goal of this study was to compare paramedic first pass success rate between two different video laryngoscopes and . Drug-assisted intubation (DAI) is a term used for any use of medications to facilitate endotracheal intubation (ETI), with or without neuromuscular blocking agents. [2, 3] The decision to intubate is sometimes difficult. "EMS personnel and physicans involved with protocol development for EMS systems in the United States, United Kingdom and similar settings with limited exposure to advanced airway management should reconsider the routine use of endotracheal intubation as the first-line strategy for airway management in out-of-hospital cardiac arrest," they stated. Patient charts were analysed for all calls to the scene (n = 9,035) taking place between June . Factors to be discussed include the initial decision to . I know intubation is the standard in the hospital, but what advantages does it have over the king? OBJECTIVE: To compare the survival and neurological outcomes of pediatric patients treated with bag-valve-mask ventilation (BVM) with those of patients treated with BVM . 7. level 1. Intubation is a common procedure doctors use during surgery or in a medical emergency to help a person breathe. AINE STATE OF MAINE DEPARTMENT OF PUBLIC SAFETY M EMERGENCY MEDICAL SERVICES 152 STATE HOUSE STATION AUGUSTA, OHN MAINE 04333 PAUL R. LEPAGE GOVERNOR J E. MORRIS COMMISSIONER SHAUN A.

OPAs are great because they're quick. The bottom line is that ET tubes are risker to place, and in most cases don't provide a lot of advantage over supraglottic airways in the prehospital setting. In this EM Cases CritCases blog - a collaboration with STARS Air Ambulance Service, and their medical director Mike Betzner, we present a challenging airway obstruction case, discuss the limitations of non-rebreather masks, using PEEP on bag-valve-masks, heliox, tips on awake intubation, and the differential for high peak inspiratory pressures in the post intubation period. Lansom et al. Anesthesiologists are airway experts, but in a different way from emergency . Role of Laryngeal Mask Airway in Emergency Department and Pre-Hospital Environment. calls, EMS agencies could station specific providers in those areas thus concentrating both general and critical pediatric patient exposure in a smaller group of providers. Prehosp Emerg Care. Most LMAs are elliptical in shape with an inflatable cuff. There are many techniques available to control a patient's airway or provide rescue ventilation and oxygenation to a patient. The indications for supraglottic airways vary widely among services based on local data, protocols, provider level and medical direction. Carlson et al. Procedures Performed by Emergency Medical Services in the United States. They don't provide as good a seal as an ET tube, but the newer ones do a pretty decent job or protecting the trachea and allowing for reasonable airway pressures. What is the primary advantage of EMS intubation? The airway is protected from emesis [vomit] and air directed into the tube goes only into the lungs. Intubation is successful less often than in the hospital, and alternative forms of airway management are more often needed. Be bold, go against the grain and feel empowered to come up with crazy ideas…. Key Points. Intubation is an invasive procedure and can cause considerable discomfort. Rates of first-time success will be lower than endotracheal intubation performed under controlled conditions in the operating room. Ramachandran et al. The i-gelTM, a modification of the LMA device, was invented in 2003. Many years ago our operating room administration decided that the bath towels we were using to position the head for intubation were a potential danger for shedding lint. Search Strategy: Pubmed was searched using a strategy of ((succinylocholine) AND rocuronium) AND RSI, with 27 articles resulting. In this article, learn about the types, side effects, and recovery. Correct tube placement was determined by waveform capnography. In this article, learn about the types, side effects, and recovery. Family members can ride to the hospital with the patient Responding providers can stabilize critical issues Patients transported by ambulance are seen first EMS transport is faster than being driven by a friend Historically, ETI has been a pillar in airway management for paramedics. For more information on awake intubation, see the links at the bottom of the post. 6,8,16-26. I would landmark the neck and have my cricothyroidotomy kit at the bedside. The Pros of Intubation Intubation, whether oral or nasal, has distinct advantages for controlling the airway. Due to long procedure times and low success rates, orotracheal intubation by paramedics has been associated with adverse patient outcomes in both non-cardiac arrest. The development of the LMA has been hailed as one of the most significant advances in airway management since the endotracheal (ET) tube. 28,29 Devices and techniques such as bag-valve-mask ventilation, endotracheal intubation, supraglottic airway devices, and noninvasive ventilation offer important tools for airway management in critically ill EMS patients. Furthermore, there is now increasing use of supraglottic airway devices. It is one of the first ventilator parameters set and would typically be "dialed in" to between 3 and 5 cmH 2 O, sometimes referred to as, "physiologic PEEP." 4 This positive, end expiratory, pressure serves to prevent collapse of . Endotracheal intubation is commonly used by emergency medical services paramedics in the advanced airway management of OHCA, but numerous studies question its safety and effectiveness. Airway management is a basic skill, and entails more than simple intubation. The primary indication of the use of RSI is the need for immediate control of a patient's airway when it cannot be controlled by other means and intubation and airway control is imperative. Retrograde Intubation •Needle is placed percutaneously within the trachea via the cricothyroid These advantages include: Reducing the risk of aspiration Allowing ventilation with 100 percent oxygen Eliminating mask-to-face seal Facilitating tracheal suctioning Preventing gastric distention A Cochrane systematic review was chosen as the fourth article. No studies in emergency RSI evaluating ICP as a primary end point Many questions still exist If time, would consider until further data released To be effective: administer THREE minutes prior to intubation at a dose of 1.5mg/kg Chest 2005; 127:1397-1412 Anesth Analg 2010; 110:1318-25 Am J Health-Syst Pharm 2011; 68: 1320-30 Simply defined, PEEP is the pressure above atmospheric pressure measured in the alveoli at end expiration. The aim of this study is to assess the success rates and adverse events related to the use of SGAs for primary airway management during anaesthesia in children . However, you'll typically be given general anesthesia and a muscle relaxing medication so that you don't feel any pain. This series began as a learning exercise for our emergency medicine residents . There are many techniques available to control a patient's airway or provide rescue ventilation and oxygenation to a patient. Endotracheal intubation is commonly used by emergency medical services paramedics in the advanced airway management of OHCA, but numerous studies question its safety and effectiveness. Additionally, a randomized controlled trial conducted in an ICU setting was chosen. Continuing Education Activity. Karamanos et al. 13-15 One prospective randomized controlled trial in an EMS . Question Is bag-mask ventilation noninferior to endotracheal intubation for initial airway management during advanced resuscitation of patients with out-of-hospital cardiac arrest?. Of all of the skills and medications that a paramedic possesses in their toolbox, there is none that they are more protective of than intubation. 9 A great deal of literature exists that reports the successful use of the LMA as a primary airway device and as a conduit for intubation of the trachea. On a cool fall evening, an ambulance and engine company are dispatched to assist a 44-year-old male who is having difficulty breathing. Not all situations require advanced airways and management is not always a linear process. To simplify airway management and minimize cardiopulmonary resuscitation (CPR) chest compression interruptions, some emergency medical services (EMS) practitioners utilize supraglottic airway (SGA) devices instead of endotracheal intubation (ETI) as the primary airway adjunct in out-of-hospital cardiac arrest (OHCA). Positioning the head and neck for intubation in the sniffing position can make intubation easy, or extremely hard. To simplify airway management and minimize cardiopulmonary resuscitation (CPR) chest compression interruptions, some emergency medical services (EMS) practitioners utilize supraglottic airway (SGA) devices instead of endotracheal intubation (ETI) as the primary airway adjunct in out-of-hospital cardiac arrest (OHCA). As a result, intubation success rates by paramedics are low in many EMS systems, especially in non-cardiac arrest settings. Clinical experience is required to recognize signs of impending respiratory failure. Outcome Measures: Primary outcome: first-pass intubation success. DOI: 10.1177/102490790301000112. The dispatcher reports that the patient has a history of asthma. The Effect of Prehospital Intubation on Treatment Times in Patients With Suspected Traumatic Brain Injury. The standard is electrocardiogram (ECG), pulse oximetry, end tidal CO 2 monitoring, and an automated blood pressure cuff. There was no statistically significant difference in first pass or overall successful ETI rates between DL and video laryngoscopy (VL) with either the GL or VT (adult) under simulated prehospital spinal immobilization conditions in a cadaveric model. Confirming, Maintaining , and Assisting Intubation Continuous End Tidal CO2 monitoring can confirm a tracheal intubation. The goal of airway management: Ensure adequate oxygenation and ventilation of the patient. Many years ago our operating room administration decided that the bath towels we were using to position the head for intubation were a potential danger for shedding lint. 2016 Sep-Oct;35(5):295-300. January 2003. Hawnwan Philip Moy, MD. In a hospital setting, we'll pretty much never use anything between an OPA and an ET, so it's useful to bridge the therapies. Tube Talk This month, readers respond with varying viewpoints on a July JEMS feature article by Tony Garcia, BS, BSN, RN/EMT-P, that defends the use of prehospital endotracheal intubation (ETI) in . Airway management can be addressed with a number of tools and techniques. The Paramedic MICA RSI trial in Victoria, Australia was one randomised controlled trial(4) examining the benefit of rapid sequence induction and intubation for head injured patients. 3. My plan would involve an awake intubation, ideally done with an intubating bronchoscope. In-hospital management for these patients typically includes endotracheal intubation (ETI), which provides definitive control of the airway, reduces aspiration risk, and allows for mechanical ventilatory support. A good wave form indicating the presence of CO2 ensures the ET tube is in the trachea. Endotracheal intubation using rapid sequence intubation (RSI) is the cornerstone of emergency airway management. Airway management is a key skill in any helicopter emergency medical service (HEMS). They can be dropped in a second, and make it easier to bag a patient until intubation, or LMA, or King, or whatever the hell else is used. A previous meta-analysis reported pre-hospital intubation success rates of 0.849 for . Endotracheal intubation is a primary airway management technique. The primary objective of this study was to determine if endotracheal intubation procedures are more likely to occur in geographic clusters of pediatric calls. Endotracheal intubation (ETI) is one of the mainstay tools in the paramedic's airway toolbox. The purpose of this systematic review is to identify and synthesize the evidence available to support the development of evidence-based recommendations and guidelines for prehospital airway management. January 2015. Hong Kong Journal of Emergency Medicine 10 (1):57-62. Positioning the head and neck for intubation in the sniffing position can make intubation easy, or extremely hard. Intubation is an invasive procedure and can cause considerable discomfort. 1report that the incidence of failure of the LMA Unique TM (defined as an airway event requiring removal of the device and subsequent tracheal intubation) was 1.1% (170/15,795 patients).
