Organizing The Team:
A suppression piece responding to an EMS emergency needs to be a functioning team. On any given fire event we all have very defined roles. One bucket is the nozzle man, the other is the pipe man advancing hose and backing up the nozzle man. One bucket is hook and can while the other is the irons. We need to be just as specific during an EMS emergency. There are four areas of responsibility in any standard patient care scenario: 1) Patient Assessment, 2) Patient treatment, 3) Patient removal, and 4) Overall scene management. Lets talk about these one at a time.
Patient Assessment:
In my opinion the physical assessment team from the suppression platform is made up of the two bucket people the engine medic and the firefighter. They work together as a cohesive team performing the physical assessment, attaching the EKG monitor, and obtaining vital signs. Sometimes I walk into an EMS scene to witness the lonely engine medic up to his elbows in EMS equipment interacting with the patient while the other three members of the crew stand and watch. If you are the firefighter on an ALS engine you play a vital role in all EMS calls. Get with the medic and find out how they operate and how you can be a part of the assessment and treatment team. Below is just one way of approaching the patient assessment of a medical patient. We are not addressing traumatic patients or technical rescue scenes in this article. The following assessment is what I have been teaching ALS interns to do for years. It gives you a good solid framework to operate from. Start by memorizing the steps and you will always be organized in your approach.
Below are seven general steps to a medical
assessment. Although they are organized
in a general sequential order the order may be modified to best address the
patient’s specific needs and underlying medical condition. The items marked with an (*) are best
performed by the lead assessor who will be performing the physical assessment
and actually touching and interacting with the patient directly.
- 1) General Impression
As
the assessment team approaches the patient they should ask themselves, does
this patient look sick, in distress, bad, or good? A general impression is a very important
building block to the rest of the assessment, but should in no way lead the
provider to jump to conclusions and cut corners on the rest of the
assessment. For example, you may have
been dispatched to an unconscious diabetic emergency. Upon approaching the
patient you see an unconscious person breathing deeply. This does not mean the providers should jump
to obtaining a blood glucose level and then immediately start an IV without measuring
vital signs or any further assessment.
Jumping to conclusions and cutting corners is a common provider error
during this step. Neglecting to garner
all the other very important and necessary information can lead to wasted time,
effort, and improper treatment. This
tactic works most of the time as long as the dispatch information is correct,
the patient has no other complications, and the treatment plan is straight
forward. When operating from a
suppression platform alone It is much quicker to jump to a conclusion at this
phase and perform all the needed ALS skills prior to the transport unit’s
arrival thus it is an enticing option, but if we want to be quality EMS providers we need to be well disciplined and assure every patient receives a good
patient assessment regardless of any preconceived notions or impressions. Only after the full assessment is performed
should the treatments be initiated. The
general impression phase is when providers very well may jump to a conclusion
based on experience and clinical judgment. Instead of immediately acting upon
that notion the providers should continue to perform the assessment, gather all
the information, and prove the initial impression true or false. If there are sufficient providers on scene
interventions may be assigned throughout the assessment process, but the lead
assessor needs to remain on task and complete the assessment to provide a full
picture of the patient’s condition.
- *2) Airway
Does
the patient have a patent airway? Are they talking? Are there any immediate
interventions necessary to improve the airway? Does the patient require an NP
airway, an OP airway, suctioning, or supplemental Oxygen? Does the patient require intubation? Airways
requiring intubation should be sized up using the LEMONS acronym. If any airway
interventions are required they should be immediately provided.
Think L-E-M-O-N-S When Assessing an airway that may require intubation.
Look externally.
There may be some physical clue or foreign object that portends difficulty.
Evaluate using the 3:3:2 rule. Can the patient fit three fingers between
the incisors? A mouth that can open that far has good temporomandibular joint
mobility. Is the mandible length three fingers from the mentum to the hyoid
bone? That's a nice, normal length; either shorter or longer makes ventilation or
intubation trickier. Last, the distance from the hyoid to the thyroid tells you
something about neck length--two fingers' distance is ideal.
Mallampati classification. If the patient can cooperate, ask her to stand
or sit up, open the mouth, stick out the tongue, and say, "Ahh." The
structures that are visible compose Mallampati class I (the easiest airway),
II, III, or IV (most difficult). If you see the tonsillar pillars, that's
Mallampati class I. If all you can see is the palate, that's class IV. In order to gain any beneficial information from this assessment tool you need to perform this while the patient is still conscious so you need to
A Mallampati
class IV always will be a Cormack-Lehane grade III or IV. This is going to be
tough, and you need to be thinking about what your alternatives will be.
Obstruction. Look for anything that might get in your way. The enemies of
airways include soft tissue swelling from smoke inhalation, burns, broken
necks, trauma to the face or neck, foreign bodies in the airway, and excessive
soft tissue from obesity.
Neck mobility is
desirable. Unfortunately, many patients who need resuscitation in the emergency
setting require cervical collars or have compromised neck mobility, and you may
not be able to move them into preferred positions for establishing a definitive
airway.
Emergency
providers have the luxury of thoroughly evaluating only around a third of
patients who need an airway established, because most are too sick or injured
to allow much evaluation.
Most
important, ask yourself, "Will I be able to ventilate this patient"
with a bag valve mask? Also ask yourself, "Will I be able to intubate this
patient? Could I do a cricothyroidotomy if I needed to?”
Saturation: What is the patient’s O2
saturation? Are they on supplemental oxygen? Be sure to preoxygenate with an
NRB and a NC with ETCO2 monitoring. Keep
the NC in place during intubation as this will provide passive oxygenation and
help maintain the patient’s O2 saturation during intubation.
Even a
thorough advance evaluation will help you identify difficult airways only about
50% of the time, so be prepared in any case (Boschert, Norris)
- *3) Touch patient, radial pulse (skin color, temp, moisture)
This
is the time to introduce your team and ask permission to touch the patient if necessary. A good beginning is to feel the patient’s
radial pulse. By just taking a radial
pulse you can determine if there are signs and symptoms of shock. Is the pulse fast or slow? Are they cool and clammy
to the touch? Is there skin moist or dry?
Is the radial pulse even palpable?
If not, do they have a brachial or carotid pulse? Are the pulses equal in strength on both
sides? At this point you should have
enough information to form a good impression of the severity of the patient’s
condition.
- *4) Check eyes for reactivity and conjunctiva.
Ask
the patient to close their eyes. This
will tell you if they have the ability to follow simple commands. Then ask them to open their eyes. By doing this, most times you can see the reactivity
of the pupils without using a pen light.
If needed use a pen light to measure the pupillary response. While you are examining the eyes pull down
the lower eyelid and examine the conjunctiva. Is it pale (hypoxia), pink
(normal), jaundice (hepatitis/liver failure), or is there any subconjunctival hemorrhaging
(severe vomiting or choking).
- 5) Gown the patient at this time if feasible
By
putting the patient in a gown now you will have full access to the upper part
of their body to listen to lung sounds, apply EKG electrodes, and perform an
abdominal assessment. If there is no gown
readily available then take this time to expose the chest as necessary to
perform the assessments. This step is
particularly important for pediatric or infant patients as it gives us the
opportunity to expose the patient and examine the entire body for signs of
abuse or neglect. With an infant patient
remove all the clothes. Remove and examine the diaper for saturation or signs
of abuse or neglect. Then work with the
caregivers to replace the diaper. This
will build a good rapport with the caregivers and allow you the opportunity to
thoroughly examine the patient.
- *6) Count Respirations and Auscultate Lung Sounds
Listen in three places in the front and at least 4 places in the back. The right middle lobe is best heard with your stethoscope directly under the right breast midaxillary. Most disease processes are present in the lower lobes which are best heard from the posterior as these lobes overlap the frontal lobes with the largest part of the lobes taking up the majority of the posterior side as you can see from the illustrations below.
- 7) Obtain vital signs and perform diagnostic tests:
Patient Treatment
The treatment of the patient is dictated by local protocol and directed by the lead medic on the scene. Just as the Medic and firefighter are the assessment team they are also the primary treatment team. More critical calls such as a cardiac arrest may call for the driver to become engaged in patient treatment as well, but the treatment of most emergency patients can be handled very well by the bucket medic and firefighter team.
Patient Removal
The driver of the engine is in the best postion to be in charge of the removal of the patient from the scene. As the assessment and treatment team go to work they can be be scoping the best and easiest way to extricate the patient from the home. They should meet the incoming EMS transport unit and communicate any equipment needs for removing the patient from the scene giving the EMS crew a short briefing on the location and general condition of the patient. Regardless of the driver's level of EMS training he can tell if the patient is really sick or doing ok, and the driver will know if a stair chair is needed, what the best entrance to the home to use, etc.
Overall Scene Management
Overall scene management and safety is the job of the engine officer. The engine officer should be interacting with the family in a positive manner, taking notes on the assessment findings for the assessment crew, and keeping a wary eye out for any safety concerns.
Preparedness:
The engine medic may find himself in some precarious remote locations rendering patient care such as upside down in a car, over an embankment 20 feet below the road, in the middle of a creek bed, or behind mounds of personal belongings in a horder's home. Sometimes its difficult to carry all of our equipment and bags to such areas. A prepared engine medic has all the essential assessment and treatment equipment close at hand at all times. Ask yourself, what do I need to fully assess someone and save a live in the first 5 minutes of an emergency. The best engine medics I know carry some sort of small personal go bag packed with all the essentials. Below are pictures of one such bag.
Assessment Tools
Stethoscope
Adult B/P cuff
Small flashlight (Penlight)
Finger Pulse Ox
PPE
Safety Glasses
Surgical Masks
N95 Masks
Hand Sanitizer
Bleeding Control
4x4's
a 5x9
a tourniquet
Below are pictures of one such bag carried by a top notch engine medic from the Fairfax County Fire Department in Virginia. What are your thoughts and feelings on tricks of the trade, methods, and techniques on how to be a better engine medic? Comment below.
