Introduction

The following guidelines are limited to information pertinent to the assessment, monitoring and care, during transport, of clients with a specific (suspected or confirmed) medical or surgical condition.

If possible, the nurse should review the care of a particular client with a consulting physician before transport.

For details concerning the clinical presentation, assessment and pre-transport management of clients with such specific medical or surgical conditions, see Clinical Practice Guidelines for Nurses in Primary Care and Pediatric Clinical Practice Guidelines for Nurses in Primary Care (First Nations and Inuit Health Branch 2000, 2001).

General Guidelines for All Urgent or Emergency Medevacs

For all seriously ill or injured clients, the following principles apply:

  • Stabilize ABCs before transport begins
  • Administer high-flow oxygen through a non-rebreather mask with reservoir bag
  • Establish two secure large-bore IV lines
  • For air medevacs, use of pressurized aircraft is recommended
  • If air medevac must be by unpressurized aircraft, discuss with the pilot, before the flight begins, the optimal cabin altitude (see Appendix 4-1, "Suggested Cabin Altitude Restrictions," below, this chapter)
  • Collect the basic supplies that should be carried on all trips; in addition, bring supplies according to the client's specific needs (see "Basic Interfacility Transport Equipment," in chapter 6, "Equipment and Supplies)

Head and Neck (Face, Eyes, Ears, Nose and Throat)

Maxillofacial Injury

Effects of Air Transport

Facial trauma may result in airway compromise. Tissue swelling may increase with flight, further compromising the airway. Remember, mid-face fractures may be associated with pneumo-encephalopathy, so careful transport is required.

In addition, facial injuries are often associated with cervical spine injury, so C-spine precautions must be taken.

For clients whose jaws are wired, ensure availability of a means of quick release in the event of air sickness (e.g., wire cutters).

Management: Considerations for Transport

  • Airway should be secured before transport
  • If the airway is not secured, insert an oropharyngeal airway, but be careful not to cause vomiting
  • If the client is conscious, do not insert airway
  • Give oxygen (humidified if possible), and keep oxygen saturations ≥95%
  • Elevate head to 30 degrees (immobilize using C-spine precautions)
  • If possible, position client on side, to protect the airway
  • Ensure that suction equipment is readily available
  • An antiemetic (e.g., dimenhydrinate) may be used
  • Monitor ABCs and neurological status frequently during transport, as these type of injuries may be associated with intracranial damage
  • Because of the nature of the injury, constant care and reassurance will be required to allay the client's anxiety and prevent panic
  • Proper mouth hygiene will contribute to reassurance
  • Position client with head toward the nose of the aircraft
  • If possible, use pressurized aircraft
  • Restrict aircraft cabin altitude to 1000 ft above ground level (AGL)

Eye Disorders and Eye Trauma

Effects of Air Transport

  • Retinal hypoxia
  • Gas expansion in globe causes vascular or optic nerve compression and possible extrusion of the intraocular contents
  • Corneal drying
  • Tension on optic nerve
  • Vomiting increases intraocular pressure

Management: Considerations for Transport

  • If possible, consult an ophthalmologist for cases of eye trauma before flight
  • Give humidified oxygen, and keep oxygen saturations ≥95%
  • For eye injuries, keep the eye covered with a sterile patch or an eye shield; apply dressings firmly enough over closed lid to prevent the eye from opening but lightly enough to avoid pressure on the globe
  • Protect extruded eyes with moist dressings, with a cup or cone covering
  • If an open eye injury is present, do not use eye drops or ointments
  • Transport by stretcher; elevate head 30–45 degrees
  • Do not let client bend over or perform tasks that might increase intraocular pressure
  • An antiemetic (e.g., dimenhydrinate) may be used
  • Give analgesia as needed (discuss with a physician beforehand, if possible); note that morphine can cause pupillary constriction
  • Reduce anxiety by offering reassurance and orienting the client to the aircraft
  • Monitor client closely for new or evolving symptoms and signs
  • Consider sedation as indicated
  • Position client with head toward the nose of the aircraft
  • If possible, use pressurized aircraft
  • Restrict aircraft cabin altitude to 2000 ft AGL

Upper Respiratory Tract Infection or Congestion

Effects of Air Transport

Gas expansion causes pressure changes, which result in increased congestion and pain in the tissues of the upper respiratory tract.

Management: Considerations for Transport

  • Request a slow, gradual descent
  • Restrict cabin altitude in unpressurized aircraft
  • Awaken sleeping clients
  • Encourage maneuvers to equalize pressure in the middle ear and sinuses with that of the atmosphere
  • Decongestants (oral or nasal) may be of benefit

Epiglottitis

Effects of Air Transport

  • Swelling of epiglottis increases

Management: Considerations for Transport

  • Secure airway before transport
  • Intubation may be needed; this procedure is not within the CHN's scope of practice and must be performed by authorized emergency transport personnel (e.g., physician, emergency flight nurse or paramedic)
  • If the client is not intubated, provide oral airway and ventilatory assistance with bag-valve mask (BVM) device as required
  • Give humidified oxygen, and keep oxygen saturations ≥95% (monitor with pulse oximetry, if available)
  • Start IV therapy with normal saline (unless insertion of an IV line would worsen anxiety and airway compromise)
  • Monitor ABCs and vital signs closely
  • Give nothing by mouth (NPO) if unable to swallow saliva
  • Position client with head elevated and toward the nose of the aircraft
  • Restrict aircraft cabin altitude to 3000 ft AGL

Respiratory System

Respiratory Insufficiency or Hypoxia

Effects of Air Transport

  • Increased hypoxia
  • Gas expansion may result in spontaneous pneumothorax (especially in high-risk clients and those with history of pneumothorax)
  • Dehydration
  • Vomiting, with potential for aspiration

Management: Considerations for Transport

  • Protect airway by inserting an oropharyngeal airway if necessary
  • Assist ventilation as required with bag-valve mask (BVM) device

  • Monitor for evidence of pneumothorax
  • An antiemetic (e.g., dimenhydrinate) may be used
  • Have appropriate equipment and supplies available (e.g., oral airways, BVM device, IV supplies, suction, 14- to 18-gauge needles or angiocatheters to perform needle decompression in the event of tension pneumothorax; see "Pneumothorax," below)
  • Reassure and support client to reduce apprehension
  • Position client with head elevated and toward the nose of the aircraft
  • Restrict aircraft cabin altitude to 2000 ft AGL

Pneumothorax

A client with pneumothorax, especially if induced by trauma, is at significant risk during air transport. All cases of pneumothorax must be treated before air transport. Treatment may include inserting a chest tube. Consultation with a physician is essential.

Clients and escorts with a history of spontaneous pneumothorax require special consideration. Consultation with a physician is recommended.

Effects of Air Transport

  • Increased hypoxia
  • Expansion of gas in the pleural space, which may cause an increase in the size of the pneumothorax and may result in tension pneumothorax

Management: Considerations for Transport

  • Protect airway by inserting an oropharyngeal airway if necessary
  • Assist ventilation as required with bag-valve mask (BVM) device
  • Give high-flow oxygen, and keep oxygen saturations ≥95% (monitor frequently with pulse oximetry, if available)
  • Start IV therapy with normal saline
  • Insertion of a chest tube may be required before transport; this procedure is not within the CHN's scope of practice and must be performed by authorized emergency transport personnel (physician, emergency flight nurse or paramedic)
  • Monitor ABCs and vital signs frequently
  • Observe for development of tension pneumothorax; be prepared to carry out needle decompression if tension pneumothorax occurs
  • Have appropriate equipment and supplies available (e.g., oral airways, BVM device, IV supplies, suction, needle decompression kit)
  • Needle decompression kit:
    •    variety of IV cannulas (#14, 2 inch for adults; #16, 1.5–2 inch for adolescents and older children; #18, 1.5 inch for children; #20 1.5 inch for infants)
    •   skin disinfectant
    •   gloves
    • tape
    • stopcock
    • small-bore latex tubing (3–5 inches [7.5–12.5 cm])
    • one-way flutter valve
    • dressing material
  • Position client with head elevated and toward the nose of the aircraft
  • Restrict aircraft cabin altitude to 2000 ft AGL

Chronic Obstructive Lung Disease (COPD)

Effects of Air Transport

  • Increased hypoxia
  • Possibly spontaneous pneumothorax

Management: Considerations for Transport

  • Protect airway by inserting an oropharyngeal airway if necessary

  • Reassure and support client to reduce apprehension
  • Position client with head elevated and toward the nose of the aircraft
  • Restrict aircraft cabin altitude to 2000–4000 ft AGL

Cardiovascular System

General

Effects of Air Transport

Clients with cardiovascular problems are affected by altitude and acceleration forces. The effects of increasing altitude include hypoxia (which may aggravate existing ischemia and cardiac failure), increase in heart rate, increase in respiratory rate, changes in systolic blood pressure, changes in cardiac output and increase in myocardial consumption of oxygen. Gravitational forces may cause hypotension and tachycardia.

Each client with a cardiovascular disorder should be assessed individually with respect to age, general state of health, extent of myocardial compromise and presence of complications.

For clients with myocardial infarction (MI), it is preferable if personnel with advanced cardiac skills, using a portable cardiac monitor, evacuate the client, if time and aircraft permit, especially if the infarction is complicated. In clients suffering from acute MI, thrombolytic therapy should be considered before transport, unless contraindicated, but only if ordered by a physician.

Angina, Myocardial Infarction and Congestive Heart Failure

Effects of Air Transport

  • Hypoxia may aggravate existing ischemia and cardiac failure
  • Gravitational forces may cause hypotension and tachycardia

Management: Considerations for Transport

  • Stabilize ABCs before transport, as follows (the sequence is important):
    • If client is in cardiogenic shock, secure the airway, and ventilate to reduce work of breathing
    • Give high-flow oxygen, and keep oxygen saturations ≥95% (monitor frequently with pulse oximeter, if available)
    • Start IV therapy with normal saline to keep vein open
    • Be prepared to treat hypotension as required; in these conditions, hypotension is related to poor cardiac contractility, consult a physician regarding appropriate treatment (e.g.,medication)
  • Treat and stabilize ischemia, MI or CHF appropriately before transport, with the intention of preventing complications
  • Limit oral intake
  • Insert a Foley catheter if the client is seriously ill or has received a diuretic (e.g., furosemide)
  • Institute cardiac monitoring (if available); watch for signs of cardiac arrhythmias
  • Monitor ABCs, vital signs, intake and output
  • Monitor for signs of complications, such as arrhythmias, pulmonary edema or hypotension (shock), and treat accordingly; consult a physician as necessary for advice and medication orders
  • Sedate to minimize risk of arrhythmia and for apprehension as required (discuss with a physician, if possible)
  • Be prepared with medications to treat increasing chest pain or acute pulmonary edema (e.g.,nitroglycerin, morphine, furosemide)
  • Be prepared to perform CPR in the event of cardiac arrest
  • Have appropriate equipment and supplies available (e.g., cardiac arrest board, airways, BVM device, IV supplies, suction, air sickness supplies)
  • Position client on stretcher with head elevated
    30–45 degrees and toward the nose of the aircraft (except for clients with known right ventricular infarct)
  • Restrict aircraft cabin altitude as follows:
2000 ft AGL 4000 ft AGL 6000 ft AGL
Moderate to severe CHF Mild CHF MI 8--24 weeks previous
Acute MI (within 8 weeks)   Stable angina
Cyanosis with right ventricular failure    
Unstable angina    

Note: AGL = above ground level. 1000 ft = 304.8 m.

Hypotension

Effects of Air Transport

  • Redistribution of blood flow
  • Increased hypoxia

Management: Considerations for Transport

  • Stabilize blood pressure as much as possible (with fluid) before transport
  • See "Shock," in chapter 14, "General Emergencies and Major Trauma," in the adult clinical guidelines (First Nations and Inuit Health Branch 2000)
  • Give high-flow oxygen, and keep oxygen saturations ≥95% (monitor frequently with pulse oximeter, if available)
  • Monitor ABCs, vital signs, intake and output closely
  • Insert Foley catheter
  • Have appropriate equipment and supplies available (e.g., cardiac arrest board, airways, BVM device, IV supplies, suction, air sickness supplies)
  • Position client supine with head flat or in Trendelenberg position if necessary (but do not use this position if shock is cardiogenic in nature)
  • Position client's head toward the tail of the aircraft if hypovolemia is present
  • Restrict aircraft cabin altitude to 2000 ft AGL

Anemia

Effects of Air Transport

  • Hypoxia

Healthy adult males with normal hemoglobin levels will tolerate an altitude of approximately 6000 ft (1829 m) without symptoms or signs of hypoxia; however, oxygen saturation will be about 90% to 93%.

Various factors will influence an anemic individual's "safe" altitude, including acute or chronic onset of the condition, compensatory mechanisms in play, associated underlying lung or heart disease, oxygen-carrying capacity of the blood and presence of sickle cell anemia.

Anemic clients (hemoglobin < 90 g/L) have reduced oxygen-carrying capacity. The body compensates to some extent by increasing cardiac output and ventilation. These compensatory mechanisms are more efficient when the anemia is chronic rather than acute.

Management: Considerations for Transport

  • Give humidified oxygen, and keep oxygen saturations ≥95% (monitor with pulse oximeter, if available)
  • Start IV therapy with normal saline (run at maintenance rate)
  • Monitor client's overall clinical condition closely: ABCs, vital signs, oxygen saturations
  • Position client with head toward the nose of the aircraft
  • Restrict aircraft cabin altitude to 3000 ft AGL (2000 feet AGL for clients with sickle cell anemia)

  • Keep cabin well ventilated and cool
  • Instruct client to focus on distant objects (e.g., the horizon)
  • Advise client to avoid unnecessary head motion and to move slowly

Management: Considerations for Transport

  • Protect the airway at all times
  • Ensure that suction is available
  • Place client in upright position if it is safe to do so
  • Advise client to keep head still and eyes closed
  • Encourage client to gain sense of position (by looking out the window)
  • Keep cabin temperature cool
  • Give oxygen intermittently
  • Have emesis cups or bags readily available
  • An antiemetic (e.g., dimenhydrinate) may be used

Bowel Obstruction or Paralytic Ileus

Effects of Air Transport

  • Gas expansion resulting in increased intra-abdominal distension, pain and vomiting

Management: Considerations for Transport

  • Prepare to protect and support airway should vomiting occur (e.g., oropharyngeal airway, suction)
  • Start IV therapy with normal saline; run at a rate adequate to maintain hydration, unless the client is being treated for shock
  • Give nothing by mouth (NPO)
  • Decompress stomach using a nasogastric tube to straight drainage or low suction; do not clamp
  • Monitor client's clinical status closely: ABCs, vital signs, pulse oximetry (if available)
  • Watch for increasing abdominal distension
  • An antiemetic (e.g., dimenhydrinate) may be used
  • Give analgesia as needed (discuss with a physician beforehand, if possible)
  • Position client with head elevated and toward the nose of the aircraft
  • Restrict aircraft cabin altitude to 2000–4000 ft AGL

Abdominal Injuries (Blunt Trauma or Penetrating Wound)

The most prominent signs and symptoms of blunt trauma injury to the abdominal organs tend to be those related to intra-abdominal bleeding, namely shock. In addition, when the contents of organs damaged by blunt trauma enter the abdominal cavity, signs and symptoms of peritoneal irritation occur (i.e., rebound tenderness, rigidity of the abdominal musculature, vomiting and abdominal distension).

A penetrating abdominal wound is one in which the abdominal wall and the peritoneum have been pierced or torn. Signs and symptoms of shock may also be present, but are usually not as marked as in severe hemorrhage from a solid intra-abdominal organ.

Effects of Air Transport

  • Hypoxia
  • Gas expansion resulting in increased intra-abdominal distension, pain and vomiting

Management: Considerations for Transport

  • Administer oxygen as required, especially if the client is in shock or there are associated chest wounds
  • Start IV therapy with normal saline, preferably through two large-bore needles; run at maintenance rate unless the client is being treated for shock
  • Do not attempt to replace intra-abdominal contents (e.g., bowel) into the abdominal cavity
  • Cover wound with a sterile dressing and keep the dressing wet with normal saline
  • Give nothing by mouth (NPO)
  • Insert a nasogastric tube with low suction, as well as a rectal tube if required
  • Insert a Foley catheter, and maintain careful record of intake and output
  • Give IV antibiotics as ordered by physician; consider tetanus prophylaxis for a penetrating wound
  • Give analgesia as needed (see note below about narcotic analgesia)
  • Monitor client's clinical status closely: ABCs, vital signs, pulse oximetry (if available)
  • Watch for increasing abdominal distension
  • Monitor respiratory status (especially if there are associated chest wounds)
  • Position client with head slightly elevated and toward the nose of the aircraft and with knees bent to prevent tension on the abdomen
  • Restrict aircraft cabin altitude to 2000–4000 ft AGL

Acute Surgical Abdomen (Including Appendicitis)

Effects of Air Transport

  • Hypoxia
  • Gas expansion resulting in increased intra-abdominal distension, pain and vomiting

Gas-forming bacteria in an inflamed appendix may result in distension of the appendix. The appendix may rupture if aircraft cabin altitude is not restricted.

Management: Considerations for Transport

  • Administer oxygen as required, especially if the client is in shock
  • Start IV therapy with normal saline, preferably through two large-bore needles; run at maintenance rate unless the client is being treated for shock
  • Give nothing by mouth (NPO)
  • Insert a nasogastric tube with low suction, as well as a rectal tube if required
  • Insert a Foley catheter, and maintain careful record of intake and output
  • Give IV antibiotics as ordered by physician
  • Give analgesia as needed (see note below about narcotic analgesia)
  • Position client supine with head slightly elevated and toward the nose of the aircraft and with knees bent to prevent tension on the abdomen and to keep any peritoneal contamination localized; avoid sudden movements and jolts
  • Restrict aircraft cabin altitude to 2000–4000 ft AGL

Use of Narcotic Analgesia

Narcotic analgesia may mask the physical signs of peritoneal irritation and may interfere with the client's evaluation at a treatment facility. There is some controversy about the use of pain control in the presence of acute abdomen. Some recent literature supports the use of narcotics, which may help to make the client more comfortable and capable of participating in the examination. The client's condition and comfort level, as well as the time lapse before transfer can be completed, are factors to consider in the decision to administer a narcotic.

If possible, consult with a physician before administering narcotics.

Musculoskeletal System

  • Position client with head toward the nose of the aircraftRestrict aircraft cabin altitude to 4000–5000 ft unless a head injury or other condition is present that dictates a lower altitude

SPINAL CORD INJURY

Effects of Air Transport

  • Excessive movement
  • Gravitational forces
  • Swelling of neurological tissues

Management: Considerations for Transport

  • Stabilize ABCs
  • Secure airway
  • Intubation should be carried out before transport if the airway is unstable or compromised; this procedure is not within the CHN's scope of practice and must be performed by authorized emergency transport personnel (e.g., physician, emergency flight nurse or paramedic)
