Hypoglycemia

M406

  • Glucose level < 70 mg/dL or glucometer reads LOW
  • If patient can swallow, 15g oral glucose or high glucose fluid (juice)
  • If patient cannot swallow, 12.5 – 25g D50W via IV/IO (treatment with D50W through IO should be viewed as a last resort effort)
  • If unable to establish IV/IO, 1mg Glucagon IM

Hyperglycemia

X101

  • Glucose level > 400mg/dL or glucometer reads HIGH
  • 500-1000ml IV/IO fluid bolus during transport if no pulmonary edema

  • If positive for stroke symptoms, GO TO STROKE – M414

Head/Spinal Trauma

S501

  • Maintain airway and administer oxygen as necessary to maintain SpO2 >95%
  • Respiratory goal is to maintain normal rate of 10-12/min to maintain ETCO2 of 35-40 mmHg
  • ONLY with assymetric pupils (> 1mm dif) and comatose, hyperventilate to goal ETCO2 of 30 mmHg
  • Stop hyperventilation if pupils normalize
  • ONLY with assymetric pupils (>1 mm dif) and comatose, consider 500 ml of 3% saline

Toxicological

M411

  • Evaluate the scene for provider safety and take appropriate precautions
  • Poison control: 513.636.5111; medical orders MUST come from Medical Command
  • Consider that patients may have multiple toxins on board
  • Consider that patients may or may not be compliant
  • Only treat patients who are symptomatic
  • Transport all patients and notify receiving hospital

Altered Mental Status – Unknown

SB201/M406

Alcohol/drug overdose is suspected, go to Toxocological Emergencies protocol

Dysrhythmia, assess for abnormal pulse or perfusion and go to appropriate cardiac treatment protocol

Head Injury

  • Maintain airway and administer oxygen as necessary to maintain SpO2 >95%
  • Respiratory goal is to maintain normal rate of 10-12/min to maintain ETCO2 of 35-40 mmHg
  • ONLY with assymetric pupils (> 1mm dif) and comatose, hyperventilate to goal ETCO2 of 30 mmHg
  • Stop hyperventilation if pupils normalize
  • ONLY with assymetric pupils (>1 mm dif) and comatose, consider 500 ml of 3% saline

Hyperglycemia

  • If rapid glucose test >400 mg/dL or glucometer reads “HIGH”
  • Administer a fluid bolus of 500-1000 ml IV/IO during transport if no evidence of pulmonary edema
  • Place on monitor for possibility of dysrhythmia

Hypoglycemia

  • If rapid Glucose test < 70 mg/dL or glucometer reads “LOW”
  • Able to swallow and maintain airway – oral glucose 15g (or high glucose fluids like orange juice)
  • Unable to maintain airway, administer Dextrose in one of the following manners until an improvement in mental status:

    • Doses may be repeated if repeat blood glucose assessment remains below 70 mg/dL
    • Dextrose must be given through a patent IV/IO. If any suspicion of extravasation is present notify receiving Emergency Department
    • It is acceptable to dilute Dextrose with normal saline due to the high viscosity based on IV size and vein conditions
  • If unable to establish IV/IO access, administer Glucagon (Glucagen) 1 mg IM
  • Narcan 0.4 to 2 mg IV/IM if signs of possible narcotic overdose are present

Hypertension

  • Symptomatic HTN (BP systolic >200 and one of the following: headache, confusion, vomiting, blurred vision, chest pain, respiratory difficulty) should not be treated for the blood pressure in the pre-hospital setting

  • Assess patient for stroke symptoms; assess blood pressure in the opposite arm of initial reading
  • If positive for stroke, refer to stroke protocol for treatment

Hypoxia

  • Maintain airway and administer Oxygen
  • Allow patient to sit up in a position of comfort
  • Apply cardiac monitor when available

    • Encourage the patient to cough if possible;
    • If not, perform Heimlich maneuver until successful;
    • If Heimlich is unsuccessful, attempt to remove object above vocal cords with laryngoscope, a suction device and/or Magill forceps or, if object is suspected below vocal cords, intubate the trachea and push foreign body down right mainstem bronchus with the ET tube to aerate the left lung.
    • If pediatric patient, follow adult instructions for patients greater than 1 year old; for infants less than one year old with complete obstruction, initiate 5 back blows alternating with 5 chest thrusts until successful or, if unsuccessful, attempt to remove object above vocal cords with laryngoscope, a suction device and/or Magill forceps or, if object is suspected below vocal cords, intubate the trachea and push foreign body down right mainstem bronchus with the ET tube to aerate the left lung.
    • If pediatric patient with stridor, consider normal saline mist via nebulizer, place patient on cardiac monitor, and contact medical control if considering nebulized epinephrine.
  • If the patient has a history of asthma, emphysema, or COPD, AND complains of a worsening shortness of breath,
    • Albuterol (Proventil) or Duoneb via HHN. May repeat to a total of 3 treatments
    • For first treatment may add ipratropium bromide or use Duoneb
    • For asthma only, consider epinephrine 1:1000 0.3 ml IM if patient is unable to breathe in HHN
    • Consider CPAP if available
    • Consider 60 mg Prednisone PO or Solumedrol 125 mg IV
    • If the patient is pediatric and is experiencing respiratory distress with a history of asthma or wheezing:
    • Assess the need for assisted ventilation
    • Allow patient to sit in a position of comfort
    • If wheezing, albuterol 0.5 ml in 2.5 ml 0.9% NaCl nebulized
    • Initiate transport
    • May give 3 albuterol nebulized treatments. May consider adding 1 vial Ipratropium Bromide (0.5% of 0.02%) to the albuterol treatments, or substituting Duoneb. Contact medical control for consideration of epinephrine 1:1000 IM 0.01 ml/kg (max 0.3 ml)
    • For patients ages 3-16 y.o. who are awake, oriented, can take oral medications, have known asthma or reactive airway disease, or history of multiple episodes of wheezing responsive to albuterol, and are NOT currently taking steroids, have a history of cancer, diabetes, or immune deficiency, administer one of the following:

  • If pneumothorax is suspected be aware that this can develop into a tension pneumothorax. Patient will have one or more signs, including absent breath sounds on affected side (possible to be both sides), respiratory distress, hypotension, asymmetric chest rise and fall, jugular vein distension, tracheal shift away from affected side, difficulty with manual ventilation, and hypoxia
    • Maintain airway and administer oxygen. Discontinue automatic ventilator if using
    • Fully expose the entire chest and clean the procedure area of the affected side
    • Prepare for the procedure using appropriate commercial device or one of three techniques:
    • Attach a 2” or longer large bore (10-14g) IV catheter and needle to a large syringe
    • Use the IV catheter and needle with a one-way, multiposition valve (3 way stopcock) or commercial device
    • Use the IV need and catheter alone leaving it open to air
    • Insert the large bore IV catheter and needle assembly in one of two locations: a) over the top of the rib in the second or third intercostal space in the midclavicular line, or b) over the top of the rib of the fifth or sixth intercostal space in the midaxillary line
    • If a tension pneumothorax is present, then a rush of air may be heard of the plunger of the syringe will be easy to pull back
    • Remove the needle from the catheter and leave the plastic catheter in place
  • If patient is in impending respiratory failure, apply any of the following that are within the provider’s scope of practice and appropriate for patient condition:
    • Head-tilt, chin-lift
