Spotlights

The NCSRC wants to congratulate and recognize the efforts of Wendy Ayscue, BS-CPS, RRT and her second year students at Pitt Community College as well as the respiratory therapists at Pitt County Memorial Hospital in Greenville on their participation and support of beausbuddies.  Beaus Buddies Cancer Fund was formed for Beau, who was only two years old when he died of cancer.  Last fall, they hosted their first major fundraiser, an auction and golf tournament that drew support from all over their Greenville, NC, community.

The combined events raised more than $130,000, which is to assist families with everything from phone cards to make long-distance calls while their loved ones are in the hospital or to help with rent or utilities.

CMS 30 Minute Window Info from the AARC

Because there have been several hospitals in NC requesting something in writing from CMS regarding its acceptance of the AARC position statement on "Inhaled Medication Administration Schedules", we contacted AARC for advice as to what information we could pass along.

We have been told by AARC staff that CMS had a conference call in November 2008 with its survey and certification staff in its Regional Offices regarding AARC's position statement on its "inhaled medication administration schedule." The Regions were sent a copy of the position statement and it was pointed out that the policy was endorsed by the AARC's Board of Medical Directors as well. A list of the organizations that comprised the Board of Medical Directors was also provided. The organizations include the Society of Critical Care Medicine, American Society of Anesthesiologists, American College of Chest Physicians, American College of Allergy Asthma and Immunology, National Association for Medical Direction of Respiratory Care, American Thoracic Society and the American Academy of Pediatrics).

The regions in turn were to tell the state surveyors in the states within their jurisdiction that CMS has accepted the position statement as a general standard of practice for respiratory therapists in the delivery of inhaled medications. It is the AARC's understanding that at some point this issue will be incorporated into training for surveyors so they are aware of the AARC's position. CMS will not put anything in writing because to do so for every association or society that issues a practice standard would be difficult to manage and add to their administrative burden.

I will be sending the Medication Delivery Standards from BOMA (Board of Medical Advisors) as soon as I receive a copy from the AARC.

CC Respiratory Therapy Students Take 3rd in National Competition

WINTERVILLE—A team of Pitt Community College Respiratory Therapy students backed up their victory in a state quiz bowl competition in the fall with a top-five showing in last month’s American Association of Respiratory Care International Congress Quiz Bowl.

Angela Chapman, Rachel Clifford and Niya Hagans ended up placing third out of the 18 teams taking part in the national event, which was held in Anaheim, Calif. The students earned the right to represent North Carolina in the competition by winning the Sputum Bowl in September, during the N.C. Society for Respiratory Care Conference (NCSRC).

Wendy Ayscue, department chair of PCC’s Respiratory Therapy and Polysomnography programs, said her students’ thorough preparation for the national event paid off. “This was no easy feat,” she said. “They have certainly earned their bragging rights to claim third in the nation.”

In addition to the students’ impressive finish, PCC also had a good showing in the national competition’s practitioner round. Pitt graduate Rusty Sugg, who is now the director of clinical education for the college’s Respiratory Therapy program, teamed with PCC Respiratory Therapy graduate Wayne Trainor and Ray Braxton from Pitt County Memorial Hospital for the event.

The team, which won the practitioner event at the NCSRC with Ayscue as a member, won several games in California before being eliminated short of the semifinals. Ayscue was unable to attend the national competition.

LEGISLATION

COALITION ACTIVITIES

The AARC continues its tradition of participating in a number of Coalitions of like-minded associations and organizations to advance particular legislation and regulations. The AARC participation in select coalitions varies from urging greater funding for research to promoting issues that will enhance the clinical support of patients with particular illnesses. The following is a listing of some of these coalitions that the AARC presently participates in:

REGULATIONS

Based in the Washington, DC area, Anne Marie Hummel as AARC’s Director of Regulatory Affairs is raising the AARC’s profile in the area of health policy and regulations. Below is a listing of several regulations that Anne Marie is presently working on and their progress:

LOCAL COVERAGE DETERMINATIONS (LCDs)

STATE GOVERNMENT AFFAIRS
Cheryl A. West, MHA, Director of Government Affairs

LEGISLATION SPECIFICALLY AFFECTIVING RESPIRAORY THERAPY LICENSURE– Eight (8) states over the past year have had legislation submitted that directly address revisions to the respiratory therapy licensure law or practice. Of these, five (5) bills were passed and enacted:

NBRC AND LICENSURE REQUIREMENTS – The NBRC requires those respiratory therapists who graduated after 2002 to renew their credentials every five years by either taking a more advanced examination or meeting continuing educational requirements. Failure to meet the requirements will result in the expiration of the credentials and prohibition to use the trademarked credentials.
The question has been raised as to what state licensure laws contain provisions requiring the applicants for licensure to maintain NBRC credential. Clearly, initial state licensing requires that the applicant has taken the NBRC exam. Therefore, for initial licenses NBRC credentials are required.
The North Carolina Respiratory Board licensure process initially requires verified passage of the NBRC CRT exam. There is a short reinstatement time, whereby, if you have not practiced RT in one year or more, you must have the CRT credentials to reapply for a license, but renewal and reciprocity does not require a current CRT credential at this time. Look for more discussion and action on this matter in the coming year as licensure boards address this issue.

STATE POLYSOMNOGRAPHY EFFORTS – In several states efforts to license those engaged in providing sleep disorder services continue. A majority of the procedures involved and described in the scope of practice for polysomnography are respiratory services. Therefore, it is not only appropriate but also essential that state societies closely review any proposed polysomnography legislation for education and competency requirements. Moreover, since respiratory therapists have for decades been providing sleep disorder services under their own scope of practice, with absolutely no negative incidence, no provisions that license polysom personnel should infringe on the licensed respiratory therapist’s ability to continue to provide this part of their own scope of practice.

The AARC does not oppose the licensure or regulation of polysomnography personnel. The AARC, however, is opposed to any provisions that not only will jeopardize patient safety through porous competency and education requirements, but will undermine the established scope of practice of respiratory care and require the licensed respiratory therapist to obtain additional training and credentialing.
Over the past year (2008) five (5) states had legislative bills introduced that address the licensure of polysomnography. The AARC anticipates that activity at the state level will increase significantly in 2009. The AARC stands ready to assist the state societies during these challenging times.

AMERICAN RESPIRATORY CARE FOUNDATION (ARCF)
Michael Amato / John D. Hiser, MEd, RRT, FAARC

JOURNAL CONFERENCE – In 2008 the Foundation presented tow Journal Conferences:

The proceedings of presentations will be published in the Journal in 2009.

EPA PARTNERSHIP - Over 5,600 register on-line for the Train-the-Trainer web based module and 3320 have received their CRCE for completing and passing the test. This particular module has seen over 15,000 RTs register since it was placed on the web site in 2007. The ARCF has produced an additional 3 hours of train-the-trainer asthma related education. This has been made possible from a grant extension from the EPA. This web-based presentation will be available the first week of January 2009. The topics cover the expanding role of the RT in smoking cessation and allergy testing. There will be a discussion of the impact of the new EPR-3 asthma guidelines specifically related at the respiratory therapist. This will be a free CRCE course offering that will be housed on the ARCF web site.

INTERNATIONAL FELLOWSHIP PROGRAM – In 2008 the International Committee received 46 applicants for International Fellows from 24 different countries. Of these, 6 fellows have been accepted for the coming year to take place in 12 cities. An outcome from this fellowship program this past year is the translation of the AARC’s “Guide to Aerosol Delivery Devices” to Chinese and Spanish.

NATIONAL BOARD FOR RESPIRATORY CARE
Sherry L. Barnhart, RRT, RRT-NPS, FAARC, President NBRC

SLEEP DISORDERS TESTING AND THERAPEUTIC TEST DEVELOPMENT – This new Specialty Examination for Respiratory Therapists Performing Sleep Disorders Testing and Therapeutic Intervention will consist of 160 scored items and 20 pretest questions; candidates will be given 4 hours to take the examination. The NBRC Board approved the following admissions policies for this specialty examination:
Be a CRT or RRT having completed a CAAHEP accredited respiratory therapist program including a sleep add-on track, OR
Be a CRT with 6 months of full time* clinical experience in a sleep diagnostics and treatment setting under medical supervision (MD, DO or PhD), OR
Be a RRT with 3 months of full time* clinical experience in a sleep diagnostics and treatment setting under medical supervision (MD, DO or PhD).

The NBRC Board has filed applications for federally registered trademarks for the credential acronym to be awarded to successful candidates for this specialty examination that will be tied to an individual’s primary respiratory therapy credential(s). The credential acronyms are CRT-SDS or RRT-SDS to indicate Sleep Disorders Specialist.

NEW TEST SPECIFICATIONS TO BE INTRODUCED FOR CRT AND RRT EXAMINATIONS – New test specifications for the CRT Examination will be implemented with examinations administered in July 2009. A revised practice test and self- assessment examinations will be available in January 2009. Test content for the RRT Examinations will change with examinations administered in January 2010 and an updated practice test and self-assessment examinations will be available in July 2009.

CONTINUING COMPETENCY PROGRAM – The Board of Trustees of the NBRC considered and approved two changes to the Continuing Competency Program at its November 2008 meeting. This is in reference to the renewal fee charged by the NBRC for a respiratory therapist (graduate after 2002) to renew his/her credential(s) that takes affect January 1, 2009:
$0 – if they have continuously maintained their active status by paying the $25 annual renewal fee in each year after earning their credential, OR
Pay the difference between $125 and what they have paid in annual renewal fees since earning their credential(s).

Reinstatement for Expired Credentials – If an individual’s credential(s) expire, they are required to retake and pass the respective examination(s) and pay the new applicant fees as well as a lapsed credential fee of $150 per credential. (Example: An individual whose CRT and RRT credentials have expired would pay a total $880 to retake the examinations on their first attempt.
As of January 1, 2009 the NBRC implemented a six (6) month grace period for individuals whose credential(s) expire to document their CE (provided it was completed prior to their credential expiration date), pay a reinstatement fee of $250 and waive the requirement for these individuals to retake and pass the respective examination(s).

IMPORTANT TO NOTE FOR THE RESPIRATORY THERAPIST (Graduate after 2002)

It is imperative that the respiratory therapist maintains a current mailing address with the NBRC in order to receive reminders (x3) from the NBRC in reference to deadline for expiration of credentials. It is also more prudent to renew your active status with the NBRC annually with a fee of $25 while ensuring active mailing address is on file.

COMMITTEE ON ACCREDITATION FOR RESPIRATORY CARE (CoARC)
Shelly Mishoe, PhD, RRT, FAARC, Chair

ACCREDITED RESPIRATORY CARE PROGRAMS – The Commission on Accreditation of Allied Health Education Programs (CAAHEP) upon the recommendation of CoARC currently has a total of 372 accredited Respiratory Care Programs. An additional 52 programs hold a Letter of Review (LoR) which is a CoARC status signifying that a program seeking initial Accreditation has demonstrated sufficient compliance with the accreditation Standards through the Letter of Review Self Study Report (Letter of Review SSR) and other documentation. A LoR authorizes the sponsor to admit its first class of students. A LoR is recognized by the National Board for Respiratory Care (NBRC) toward eligibility to the Respiratory Care credentialing examination(s). Thirty of the accredited programs are Certification-level (100 level) and 342 are Registry-level (200-level).
CAAHEP upon the recommendation of CoARC also accredits polysomnography program as add-ons to accredited Respiratory Care Programs. There are also a total of 10 Satellite campuses, 3 evening formats, and 1 distance program (all domestic).

ENROLLMENT AND GRADUATION FROM ACCREDITED RESPIRATORY CARE PROGRAMS – Based on analysis of the 2008 Reports of Current Status (the annual reports that were submitted on September 19, 2008):

STANDARDS REVISIONS PROCESS – CoARC reviews its current standards every five years. CoARC will be working with its sponsoring organizations to develop progressive drafts over the next several months. In addition to the input from CoARC sponsors, open hearings will be scheduled on the proposed Standards to permit consideration from all applicable communities of interest regarding what should and what should not be included in the Standards. Once the final draft is reviewed and approved, it will be sent to CoARC’s sponsoring organizations for formal endorsement.

AD-HOC SUBCOMMITTEE ON INDEPENDENT ACCREDITOR STATUS – At the November 2008 Board meeting, CoARC made the decision to proceed with the process of separating from CAAHEP and become a freestanding accreditor for respiratory therapy programs. In the current structure, CoARC is a committee that makes recommendations to CAAHEP as the accreditor. CoARC formed an ad-hoc subcommittee in July 2008 to conduct a detailed assessment of its current relationship with CAAHEP, as well as to determine the advantages and disadvantages that such a decision might have on our communities of interest and the profession. The CAAHEP, CoARC’s sponsors and the educational programs were notified by letter on November 17th 2008, along with the National Network of Health Career Programs in Two Year Colleges (NN2) and the Association of Schools of Allied Health Professions (ASAHP).

This decision has been made after a thorough review and consideration of the pros and cons of pursuing independent accreditor status. With almost 40 years of operation, first as part of the AMA’s Committee on Allied Health Education and Accreditation (CAHEA), and then under the Commission on Accreditation of Allied Health Education Programs (CAAHEP system, the CoARC feels they have gained the maturity and experience to function as a freestanding organization. Reportedly, timely steps are being taken to assure recognition as the official accrediting agency for respiratory therapy education programs by the sponsors, National Board for Respiratory Care, state licensing boards, and other appropriate entities. CoARC is proposing a target separation date of January 15, 2010.

HOUSE OF DELEGATES RESOLUTIONS (DEC 11-12, 08)

#94-08-24 – Resolve that the AARC provide the option of direct deposit of state affiliate’s quarterly revenue sharing checks into affiliate’s checking account

#80-08-25 – Resolve that the AARC Chartered Affiliates Handbook (latest edition 1/08) be revised to delete: Officers Duties Sections: Treasure, line VII; Secretary, line X, and from the General Information Form, line #6 to no longer require the submission of budget information to the AARC. That the ARRC cease requiring such information from the chartered affiliates, effective immediately.”

Message from the President

Theodore Roosevelt said,
Far and away the best prize that life offers is the chance to work hard at work worth doing. <http://www.quotationspage.com/quote/2056.html>
Our work is worth doing! However such challenges as the dangers of therapist apathy and cynicism are real the defeatism and self-doubt characteristic of a pessimistic attitude will undermine and destroy such values as idealism, hope and trust if we are not proactive!

To be proactive I believe the NCSRC must represent and reflect all therapists that practice Respiratory Care in The State of North Carolina. The NCSRC also needs to make public statements on issues that affect the public health, safety, and welfare of the Respiratory patient in North Carolina and be recognized. Our organization must also represent and reflect all aspects of Respiratory Care in The State of North Carolina as well as to be seen and understood as an organization in order to promote the public health, safety, and welfare of the Respiratory patient in North Carolina.

Management of the Difficult/Failed Airway
Jhaymie L Cappiello BS RRT

Successful airway management involves both the ability to perform the procedure skillfully and to be able to recognize the signs that you may be dealing with a difficult airway. Even in the most advanced setting, the potential for a failed airway is always present. The failed airway can be defined in one of two ways, the inability to intubate and ventilate the patient to maintain an oxyhemoglobin saturation of > 90%, or the unsuccessful passage of the endotracheal tube after three attempts by an experienced clinician. The potential consequences for the patient with a failed airway can be catastrophic. It is therefore essential that a thorough evaluation be performed for each airway management situation. This evaluation should include patient anatomy, pathology and available support services to assist in optimizing conditions. Preparation and recognition of the difficult airway will optimize the clinicians’ chance for successful airway management.

Airway Management Evaluation

Airway Anatomy

  • History of a difficult airway
  • Severe Overbite
  • Mouth opening< 3 cm
  • Malampatti >2
  • Thyromental distance <6cm
  • High arched palate
  • Impaired cervical mobility
  • Large tongue
  • Edentulous
  • Obese
  • Short/thick neck
  • Bearded
  • Mandibular space rigidity
  • Sleep apnea history
  • Facial/neck trauma
  • Oral/airway tumors
  • Stridor
  • Emesis
  • Blood

Cardiovascular

  • Inability to oxygenate
  • Hypotension
  • Cardiac Dysrhthmia
  • CPR

Support system

  • Lack of equipment
  • Malfunction
  • Untrained staff

Airway management difficulty arises when a provider encounters one or more of the following obstacles: 1) difficult airway anatomy, either pre-existing or from trauma,
2) cardiovascular depression, and 3) support system failure. The table insert is a list of the more common obstacles.

A review of anatomy will provide hints into what the obstacles may be and will give the clinician a head start on how to optimize the situation prior to encountering it.  Some examples include the following: the obese patient is likely difficult to manually ventilate, the patient with stridor may have a tracheal obstruction, and the large tongue may impede your laryngeal view. Timely and properly utilized airway adjuncts are in these cases essential. Acknowledgment of anatomical obstacles and mentally preparing a response in action will facilitate your successful airway management.
A cardiovascular depressed patient adds another degree of difficulty due to existing tissue hypoxia. Hyperoxygenation may be difficult to achieve due to presenting pathology, hypotension may be exacerbated during the procedure, and chest compressions complicate laryngoscopy. Medical team cooperation is crucial for positive patient outcomes.
The airway management support system includes the airway management clinician, medical staff and available equipment. For each case, there should be an experienced operator with competency in the difficult airway and knowledge of available airway tools. The tools must be available and organized to facilitate rapid employment when encountering a difficult airway. Contiguous medical staff experience with airway management equipment and supportive airway techniques will facilitate the operators’ success.  
In review, each airway must be thoroughly evaluated for signs of potential difficulty. Look at the presenting anatomy for difficulties, determine if there is cardiovascular depression, and who/what are your support services. Doing this each time will enable the clinician to provide the best chances for a positive outcome

Reaction to the Difficult Airway

Prevention of the ‘can’t intubate /can’t ventilate’ airway failure is of paramount importance. Confidence in basic airway management techniques will yield positive results and will assist the team in establishing a definitive airway in a timely manner. When having difficulty with manual ventilation, check mask size and placement, head/jaw position, ventilation status with the insertion of an oral/nasal airway, and is there a removable upper airway obstruction or fluids that require suctioning? 
Direct vision laryngoscopy affords the clinician the chance to determine if the airway is manageable with conservative techniques. An inability to visualize the vocal chords may be due to an inappropriate laryngoscope blade and/or technique. Re-establishment of the approach paying attention to detail may help. Firm posterior rightward cricoid manipulation may bring the hard to visualize chords into view, or gentle retraction of the patients’ lip may be necessary. Support personnel with airway management skills are invaluable in assisting with these techniques. Inability to visualize any part of the vocal chords, a blind airway, should be immediately made known to assisting personnel. This will initiate early preparation for a ‘failed airway procedure’ should the need arise.
A smooth passage of an endotracheal tube is not guaranteed once the vocal chords are visualized. The clinician should have an array of different sized endotracheal tubes available, allowing for a change in tube size if resistance is met, without loss of visualization. This technique will minimize laryngoscopies, a known cause of pharyngeal edema, which could impede future visualizations.
It is important that the support personnel are aware of what the clinician is experiencing. They are monitoring the patient, providing feedback to the clinician on the patients’ condition, and will make available additional resources should the need arise.

The Failed Airway

All airways have the potential for failure. The ‘can’t intubate/can’t ventilate’ airway failure typically results in an emergent cricothyrotomy. The decision for this procedure is made when the most skilled clinician is unable to maintain a patent functioning airway and the need for a definitive airway is absolute. This decision is best made early. When a skilled operator is unable to obtain an airway following three attempts, this too is a ‘failed’ airway. With oxygenation and ventilation being supported, there is time to consider airway adjuncts and call for additional personnel if needed. The use of airway adjuncts such as bougies, introducers, LMAs’, and intubating bronchoscopes can resolve this dilemma. Readily available airway adjuncts, transtracheal jet and an emergency cricothyrotomy kit should be standard equipment for a failed airway box.  It is important to clearly discern and communicate the difference in order to pursue the proper course of action.

Conclusion

The recent article in The Journal of Clinical Anesthesia, Volume 19, Issue 1 ‘Urgent tracheal intubation in general hospital units: an observational study’, Benedetto et al, reported their most common complications noted for general care unit emergent and elective intubations were multiple attempts. Anesthesia and Analgesia Volume 99, Issue 2, Mort et al, reported a significant increase in airway related complications with laryngoscopies >2. The management of the airway should be approached with consistency and respect. When facing a difficult airway, the clinicians’ skill and knowledge must be accompanied by support systems with familiarity of both the procedure and the equipment. Appropriate preparation and response in action to each obstacle by the team of providers will enable positive airway outcomes.

Rapid Sequence Intubation

Joe Hylton, RRT-NPS
Carolinas Medical Center
Charlotte, NC

Definition

Rapid sequence intubation is defined as the delivery of a potent induction agent, followed immediately by a rapid acting neuromuscular blockade agent to induce unconsciousness and paralysis to facilitate tracheal intubation. The airway management technique rests on the fact that the patient has not fasted before intubation and predisposed to aspiration of gastric contents. Drug administration should be preceded by pre-oxygenation phase to permit a short period of apnea to safely occur between drug administration and intubation. In essence, the purpose of RSI is to render the patient unconscious and paralyzed, then intubate the patient safely and quickly without the use of bag-mask ventilation. Bag-mask ventilations are avoided to minimize the risk of gastric distension and emesis/aspiration.

Indications/contraindications

The superiority of RSI, in terms of success rates, complication rates and control of adverse of adverse effects makes it the cornerstone of emergency airway management. Contraindications are relative to the procedure. Difficult intubation is not a contraindication to RSI; it is a warning to the person performing RSI to carefully form a pre-intubation plan with emphasis on the ability to ventilate the patient should intubation be unsuccessful. The cardinal principle in assessing a difficult airway for RSI is to determine if the patient can be adequately ventilated via bag-mask ventilation; if the answer is yes, the decision is guided by the likelihood of successfully securing a tracheal airway.

Technique

RSI should be thought of as a logical process of steps to aid in success of the procedure. The seven steps are listed in the table 1.

Box 3-1.

Table 1. Adapted from the Manual of Emergency Airway Management, Lippincott, Williams, and Wilkins, ©2004. Used with

1. Preparation – The patient must be thoroughly assessed for difficulty of intubation. All preparations must be made, including equipment selection. In the case of a failed intubation, fallback plans must be made, with all necessary equipment close at hand. Cardiac and blood pressure monitoring must be utilized, along with pulse oximetry and a functioning intravenous line.

2. Preoxygenation –This is an essential piece of RSI, emphasizing the “no manual ventilations” principle. The pre-oxygenation phase of RSI should establish an oxygen reservoir within the lungs and body tissue to facilitate several minutes of apnea to occur without arterial desaturation. The oxygenation phase should begin 5 minutes before RSI medication agents are delivered to the patient. Table 2 demonstrates desaturation times for various patient circumstances. It is important to remember the time to desaturate from 90% to 0% is significantly less than the time to desaturate from 100% to 90%.

Table2

Table 2. Adapted from the Manual of Emergency Airway Management, Lippincott, Williams, and Wilkins, ©2004. Used with permission of LWW and The Difficult Airway Course.

3. Pretreatment – This phase of RSI incorporates the administration of drugs to mitigate adverse effects associated with endotracheal intubation. The effects include the intracranial pressure (ICP) response in cases of elevated ICP and the bronchospastic reactivity of the airways to the ETT in reactive airway disease. The drugs can be utilized to blunt the sympathetic discharge that occurs with laryngoscopy and intubation. The drugs are listed in Table 3.

Table3

Table 3. Adapted from the Manual of Emergency Airway Management, Lippincott, Williams, and Wilkins, ©2004. Used with permission of LWW and The Difficult Airway Course.

4. Paralysis with induction – A rapid acting induction agent is delivered in a dose adequate to produce loss of consciousness, immediately followed by the neuromuscular blocking agent, usually succinylcholine. The entire technique is based upon rapid loss of consciousness, rapid neuromuscular blockade and a brief period of apnea, without assisted ventilations before tracheal intubation occurs.

5. Protection/positioning – Apnea should be present after 20-30 seconds. If succinylcholine is utilized, fasciculations will present during this time. Sellick’s maneuver should be applied immediately on observation of the patient losing consciousness and maintained throughout the entire intubation sequence, until the ETT has been successfully placed, verified and the cuff inflated.

6. Placement/proof – The patient’s jaw should be checked for flaccidity 45-60 seconds after administration of the neuromuscular blocking agent and intubation should be undertaken. Proper attention to technique to minimize airway trauma and attention to the patient’s dentition is vitally important. The glottic opening should be visualized, the stylet should be removed and the cuff should be inflated. End-tidal carbon dioxide detection is mandatory.

7. Postintubation management – The ET tube should be secured after proper placement is confirmed. A chest film should be obtained to ensure that a right mainstem intubation has not occurred. Hypotension is a common effect seen in this phase, often caused by diminished venous blood return secondary to the increased intrathoracic pressure from positive pressure ventilation. Long term sedation should be administered for patient comfort and safety. A neuromuscular blockade agent can be given if needed.

Timing the RSI steps

Successful RSI demands a detailed knowledge of the steps taken, as well as the time required for each step to successfully achieve its purpose. RSI can be defined as a series of timed steps, with time zero being the time that neuromuscular blockade is administered. The RSI sequence, with times for each step is outlined in Table 4.

Table4

Success rates

In the emergency department, RSI has a very high success rate, approximately 99%. An international multicenter study of over 10,000 emergency department intubations was performed by the National Emergency Airway Registry (NEAR), reporting >99% success rate for RSI when utilized on patients with medical emergencies and >97% success rate for trauma patients. The NEAR investigators classified events related to intubation as follows;

  1. Immediate complications – witnessed aspiration, broken teeth, airway trauma, undetected esophageal intubation.
  2. Technical complications – mainstem intubation, cuff leak, recognized esophageal intubation.
  3. Physiological alterations – pneumothorax, pneumomediastinum, cardiac arrest, dysrhythmias.

This classification system allows for complications to be identified and all events to be captured, and avoids attributing various technical problems and physiological alterations as complications. Event rates were very low, approximately 3%.

Summary

RSI is a very successful technique for endotracheal intubation, and a cornerstone for emergency airway management. A strong technical knowledge of the RSI, along with proper laryngoscopy technique is of vital importance for the clinician employing this procedure.
