PART I. GENERAL GUIDELINES
1.
1.
These Medical
Protocols apply to adult patients age 18 and over.
2.
2.
Remember: Courtesy to the patient, the patient's
family and other emergency care personnel is of utmost importance.
3.
3.
A Hennepin
County EMS System ambulance report form must be completed on all patients and a
copy left with the patient at the hospital.
Specific prehospital care information must also be recorded on all
patient contacts as part of the System data collection program.
4.
4.
The specific
conditions listed for treatment in this document, although frequently stated as
medical diagnoses, are merely operational diagnoses to guide the paramedic in
initiating appropriate treatment. The
medical control physician, when consulted, will either concur or further
evaluate the paramedic's clinical findings and suggest an alternate diagnosis
and treatment.
5.
5.
In all
circumstances, physicians have latitude in the care they give and may deviate
from these Medical Protocols if it is felt such deviation is in the best
interest of the patient. Nothing in
these protocols shall be interpreted as to limit the range of treatment
modalities available to medical control physicians to utilize, other than the
modalities and the medications used must be consistent with the paramedic's
training.
6.
6.
MEDICAL
CONTROL: A medical control physician should be contacted as specified in
these protocols. Whenever possible,
medical control should be obtained from the hospital of destination requested
by the patient. Medical control as
required by protocol for cardiac and other non-trauma patients should be
established without delay upon completion of necessary ALS procedures. If no request for medical control has been
made before three minutes from hospital arrival, patient information only
should be communicated (for hospital notification) in lieu of medical
control. Except for load-and-go situations
with short transport times, any such delay in establishing medical control will
be explained in a System Incident Report submitted by paramedics to their
medical director and to the System Quality Improvement Officer Community
Health Department. This policy in no
way precludes establishment of medical control at any time during the run to
obtain physician advice or assistance.
7.
7.
MEDICAL
CONTROL COMMUNICATIONS FAILURE: In the occurrence of communication failure, paramedics may
perform those orders outlined in the ALS
Medical Protocols under "After Obtaining Verbal Orders" for
patients with life-threatening or potentially life-threatening conditions. Initiation and performance of these orders
must be in accordance with the paramedic's training and must be carried out as
written in these Medical Protocols. Any
instance of communications failure where procedures are carried out without a
physician's verbal order must be reported in a System Incident Report within 48
hours to the paramedic's medical director and to the System Quality
Improvement Officer Community Health Department.
8. PHYSICIAN PRESENCE AT
THE EMERGENCY SCENE:
A.
A.
If the
patient's personal physician is present and wishes to assume responsibility for
the patient's care:
1)
1) The paramedic should defer
to the orders of the personal physician as long as those orders are appropriate
and not in conflict with ALS Medical Protocols. (Paramedics should establish radio medical control any time they
are uncomfortable with carrying out orders from a patient's physician.)
2)
2) Orders given by the personal
physician should be written on the EMS report form and signed by the physician.
3)
3) The paramedic should contact
the medical control physician during transport to report treatment given and to
obtain further orders if the personal physician does not accompany the patient.
B.
B.
If a System ALS
Medical Director or medical control physician is present and wishes to assume
responsibility for the patient's care, the same guidelines apply as in (A)
above.
C.
C.
If any other
intervening physician wishes to assume responsibility for the patient when no
radio medical control exists, the paramedics should relinquish responsibility
for patient management if the physician:
1)
1) can show appropriate
identification (or is known to the paramedics); and
2)
2) agrees in advance to
accompany the patient to the hospital (exception: major multiple casualty incident); and
3)
3) signs the EMS report form
assuming responsibility and verifying orders.
·
·
If radio
medical control exists, the intervening physician should be allowed to
communicate with the medical control physician prior to the paramedics
accepting orders. If there is any
disagreement between the two physicians, the paramedics will follow the orders
of the medical control physician and allow the physicians to continue their
communication.
·
·
In the case of
multiple intervening physicians at the scene, the paramedics should request the
physicians designate one physician to direct patient care.
D.
D.
An intervening
physician not wishing to assume responsibility for care and accompanying the
patient to the hospital may be asked to assist the paramedics and/or act as a
medical consultant to them and to the medical control physician.
9.
9. PATIENT
CONSENT AND REFUSAL: Whenever an ambulance is
requested for a patient, it is the responsibility of the EMS system to treat
and transport that patient with his/her consent. Transport by ambulance should always be offered to a
patient. If a competent patient or
parents of a minor refuse treatment or transportation, they should sign the
refusal statement on the ambulance report form. If they refuse to sign, this should be documented, including witnesses'
names if possible. In general, a person
is mentally competent if he/she:
1)
1) is capable of understanding
the nature and consequences of the proposed treatment; and,
2)
2)
has sufficient emotional control, judgment, and discretion to manage
their own affairs.
Emergency care for
life-threatening conditions should never be delayed or withheld to carry out
legal consent procedures. Any time
contact with the patient occurs and the patient is not transported, the run is
a "left," not a "cancel," and requires full documentation
of all sections of the ambulance report form including what the patient (or
parent) was told at the scene regarding non-transport and any other follow-up
advice or information given at the scene.
Adults: A mentally competent adult has
the right to refuse treatment and/or transport; however, the paramedic and/or
medical control physician (by phone or radio) should explain thoroughly the
alternatives and potential consequences of this action. A medical control physician should always be
consulted if in doubt as to the mental competency of a patient, or if the
paramedic feels it is detrimental to leave the patient.
Minors: Consent or refusal of
treatment/transport of minors (less than 18 years) must be given by the child's
parent or legal guardian. Although less
desirable, consent or refusal may be given by a responsible adult (over 18)
caretaker if the parent has deliberately left the minor in the care of this
adult, and the adult is competent and capable.
If unsure whether it is appropriate to allow someone to give consent or
refuse treatment of a minor, a medical control physician should be consulted.
10.
10. EQUIPMENT: All equipment appropriate to the nature of
the call for assessment, treatment and transport should be taken to the site of
the patient at the time of initial patient contact. A list of required and optional permitted equipment for the
Hennepin County EMS System is found in Appendix A.
11. AIRWAY MANAGEMENT:
A.
A.
Airway Devices:
Oropharyngeal or
nasopharyngeal airway insertion should be attempted on all unconscious patients
for airway maintenance.
Esophageal obturator airways
and Combitubes are to be inserted only
in apneic patients unless ordered verbally by the medical control physician or,
if authorized by the ALS medical director, in patients with Glasgow Coma Score
<8 who cannot be endotracheally intubated.
The EOA should be used with caution in trauma patients (see Traumatic
Emergencies section).
Endotracheal intubation is not a required procedure
but is sanctioned in the Hennepin County EMS System for various categories of
patients. Endotracheal intubation is to
be performed only by paramedics trained and authorized to intubate and only for
those types of patients specified by the ALS Medical Director. Endotracheal intubation shall be performed
in accordance with the information and protocol contained in Appendix B and
consistent with other protocols in this document.
Other airway interventions not required but
sanctioned by the System are rapid sequence endotracheal intubation and the
establishment of surgical airways (i.e., transtracheal needle ventilation and
cricothyrotomy) for patients that cannot be ventilated by any other means. These interventions must be authorized by a
service's ALS Medical Director and shall be performed in accordance with the
information and protocols contained in Appendices C and D.
B.
B.
Adjunctive
Airway Equipment:
·
· End-tidal CO2
monitoring: An end-tidal carbon dioxide
(CO2) detector may be used (but is not required) to accomplish
confirmation of endotracheal tube placement and is most reliable in patients
with spontaneous circulation. This
device often is not able to detect CO2 in cardiac arrest patients
due to extremely low blood flow to the lungs.
·
· Pulse oximetry: A pulse oximeter may be used (but is not
required) for any patient with suspected hypoxemia, in respiratory distress, or
whenever sedating medications are administered. Obtaining a normal pulse oximetry reading does not negate the
need for oxygen therapy as specified in these protocols.
C.
C.
Drug
Administration By Inhalation or Via the Airway:
Nitronox, oxygen and albuterol sulfate are the
prehospital drugs administered by inhalation.
Of the three, Nitronox is not a required drug, but is sanctioned for use
in the Hennepin County EMS System. It
may be used to treat pain of many varieties including non-traumatic headache, back
pain, isolated musculoskeletal trauma, burns not involving the face or
respiratory tract and other medical conditions such as kidney stones and third
trimester labor. Paramedics trained and
authorized by their ALS Medical Director to administer Nitronox shall do so in
accordance with the information and protocol contained in Appendix E of this
document.
Oxygen therapy should be administered in accordance
with the following guidelines:
·
· If patient has no history of
COPD, oxygen should be administered by mask at a minimum of
10 liters per minute or, if intolerant of mask, by nasal cannula at 4-6 liters
per minute.
·
· If patient has a history of
COPD, use a nasal cannula at 2-3 liters per minute initially. Oxygen may need to be increased if the
patient’s respiratory status worsens.
·
· Patients with suspected
pulmonary burns or CO toxicity should receive oxygen by partial rebreather mask
for the highest possible oxygen delivery.
Drugs that may be administered via the
tracheobronchial tree by injection into an endotracheal tube are narcan,
atropine, epinephrine and lidocaine.
This drug administration route may be used in cardiac arrest whenever an
endotracheal tube has been placed and venous access is delayed or impossible. Medications via the ET route should be
administered at twice the IV dose and should be diluted with sterile normal
saline or water to a volume of at least 10 ml.
A suction catheter should be passed beyond the tip of the endotracheal
tube, chest compressions stopped and the drug solution quickly injected into
the catheter. This should be followed
by several quick ventilations to aerosolize the medication before resuming
chest compressions.
12. IV THERAPY: If
IV access cannot be established rapidly at the scene (in two attempts) in
patients with non-traumatic problems, begin transport to the hospital. Further IV attempts can be made during
transport, provided all other necessary treatment is being done. There should be no delay at the scene for IV
attempts on trauma patients or patients in shock--these IV's should be started
during transport.
For most patients, the
paramedic has the option of either running fluids through the IV or capping the
catheter with a saline lock. However,
as specified in these protocols, IV fluids must always be hung in situations:
1)
1)
when the
administration of multiple IV medications is anticipated; and
2)
2)
whenever it is
likely the patient will require fluid volume replacement.
At the paramedic’s
discretion, a saline lock may be established any time it is felt IV access will
be needed.
