NASOPHARYNGEAL AIRWAY
Goal of treament: |
NPA assist in airway maintenance of a compromised airway - particularly associated with trismus.
|
|
NASOPHARYNGEAL AIRWAY
Indications: |
Airway adjunct for use in patients with
potential or actual airway obstruction, particularly in circumstances where an oropharyngeal airway is inappropriate (eg. Patient has trismus or an intact gag) |
|
NASOPHARYNGEAL AIRWAY
Contraindications: |
Nil in this setting.
|
|
NASOPHARYNGEAL AIRWAY
Precautions / Complications: |
Airway trauma, particularly epistaxis.
Incorrect size or placement will compromise effectiveness. Exacerbate injury in base of skull fracture, with NPA potentially displacing into the cranial vault. Can still stimulate a gag reflex in sensitive patients, precipitating vomiting or aspiration. |
|
NASOPHARYNGEAL AIRWAY
Additional Information: |
An NPA does not protect the patient’s
airway from aspiration. The right nostril is often preferred for NPA insertion given that it is typically larger and straighter than the left. |
|
NASOPHARYNGEAL AIRWAY
Clinical Judgement Issues: |
Particular caution must be taken for
patients with trauma to the nose or suspected basilar skull fracture. The proper sized airway is slightly smaller in diameter than the patient’s nostril and is equal to or slightly longer than the distance from the tip of the nose to the earlobe. NPAs are smaller than an Oropharyngeal Airway (OPA). If the NPA size is too small it will not extend pass the tongue; one that is too long may pass into the oesophagus and result in hypoventilation and gastric distension when bag mask ventilation (BVM) is used. The nasal mucoa is highly vascular and is easily damaged. Forceful insertion can lead to trauma, bleeding, aspiration of clots and the need for suctioning. The adenoids can also be lacerated causing considerable haemorrhage. An NPA is difficult to suction through, it may kink or block and obstruct the airway. It can be difficult to insert in some patients particularly if nasal damage is present (old or current). While semiconscious patients may tolerate an NPA better than on OPA, it too can cause vomiting, aspiration and laryngospasm. In some cases a second NPA can be inserted in the nostril to maximise the use of the airway adjuncts in maintaining a patent airway. |
|
LARYNGEAL MASK AIRWAY
Goal of treatment: |
Advanced airway management to provide
patency. |
|
LARYNGEAL MASK AIRWAY
Indications: |
Impending or actual loss of airway
patency or protection, where advanced airway management is necessary, but the clinician is unable to secure airway through endotracheal intubation Rescue airway in the failed intubation algorithm |
|
LARYNGEAL MASK AIRWAY
Contraindications: |
Nil in this setting
|
|
LARYNGEAL MASK AIRWAY
Precautions / Complications: |
Failure to provide adequate airway or
ventilation Can precipitate vomiting and aspiration in a patient with intact airway reflexes Airway trauma Patient intolerance. |
|
LARYNGEAL MASK AIRWAY
Additional Information: |
An LMA does not protect the airway
from aspiration.[1] An LMA typically causes less gastric insufflation than bag-valve mask ventilation alone. An LMA is often easier to insert if there is an amount of air (50% recommended) in the cuff prior to insertion. Note: ACPs are only authorised in the use of size 3, 4 and 5 LMAs in associated patient groups. |
|
LARYNGEAL MASK AIRWAY
Clinical Judgement Issues: |
Frequently reassess the LMA
placement as it is not uncommon for the BVM to create torsion on the tube and thus twist the mask out of its anatomical seating. This is particularly so in the prehospital setting where patients need to be moved, often out of awkward locations and at a rapid pace. |
|
Magill Forceps
Goal: |
The removal of a foreign body from the
airway or the manipulation of an endotracheal or gastric tube. |
|
Magill Forceps
Indications: |
Removing an airway obstruction
Insertion or manipulation of an endotracheal tube Insertion or manipulation of a gastric tube |
|
Magill Forceps
Contraindications: |
Nil in this setting if used in conjunction
with a laryngoscope. |
|
Magill Forceps
Precautions / Complications: |
Laryngospasm
Hypoxia due to delays in oxygenation while performing the procedure Trauma to mouth or upper airway if the Magill Forceps are used incorrectly |
|
Magill Forceps
Additional Information: |
Nil in this setting.
|
|
Magill Forceps
Clinical Judgement Issues: |
Laryngospasm may be triggered by
touching any part of the anatomy distal to the epiglottis, including the posterior surface of the epiglottis or any part of the laryngopharynx. Be cautious when moving the Magill Forceps around near the epiglottis. Be aware for the potential to cause trauma to the airway. |
|
Laryngoscopy
Goal: |
To facilitate the visualisation of the glottis
for the purpose of clearing the airway, or for the insertion of an endotracheal tube or gastric tube. |
|
Laryngoscopy
Indications: |
Clearing the airway
Insertion of an endotracheal tube Insertion of a gastric tube |
|
Laryngoscopy
Contraindications: |
Epiglottitis
|
|
Laryngoscopy
Precautions / Complications: |
Laryngospasm
Hypoxia due to delays in oxygenation while performing the procedure Trauma to the mouth or upper airway, particularly teeth / dentures Exacerbation of underlying C-Spine injuries Failure to visualise the glottis |
|
Laryngoscopy
Additional Information: |
Laryngoscopy is not advised in
patients with intact airway reflexes. It is possible to use a blade which is larger than necessary and still visualise the glottis effectively. However, using a blade which is inappropriately small will make adequate laryngoscopy impossible. |
|
Laryngoscopy
Clinical Judgement Issues: |
The QAS uses the Macintosh and
Miller disposable blades. The Macintosh, or curved blade, is designed to rest in the epiglottic vallecular, such that when the laryngoscope is elevated, the epiglottis is lifted, allowing visualisation of the larynx. The Miller blade is preferred in young children. Its straight blade is designed to lift the epiglottis directly, which is often bulkier compared to adults. An approximate age guide related to blade size Always consider the need for Manual Inline Stabilisation (MILS) Briefly assess the airway for predictors of technical difficulty (Refer to the Endotracheal Intubation CPP for a detailed outline of the LEMON pneumonic which is useful in this assessment) Consider adjuncts which may improve the position of the patient and therefore the potential success of the laryngoscopy procedure visualising the glottis on the first attempt (i.e. pillows to raise the head in adults or towels for under the shoulders of the young paediatric patient under 12 months of age) The decision to remove dentures needs to be made on a case by case basis. Generally speaking dentures should be removed for the laryngoscopy process as there is the potential for them to dislodge at a critical time during the procedure, or the dentures themselves can be damaged. Damage to lips, teeth, dentures and upper respiratory tract tissue can occur if the laryngoscope is used incorrectly, such as using teeth as a pivot. Laryngospasm may be triggered by touching any part of the anatomy distal to the epiglottis, including the posterior surface of the epiglottis or any part of the laryngopharynx. Hypoxia and hypercarbia may occur due to a lack of ventilation while laryngoscopy is being performed. Be mindful of how long your patient has been without ventilation – work swiftly and closely watch all non-invasive monitoring and the patient (i.e. pulse oximetry, cardiac monitor, and patient colour) Physiological effects can also occur including hypertension, tachycardia and sometimes profound bradycardia (particularly in the younger paediatric patient who responds significantly to vagal stimulation) In the setting of a likely or confirmed airway obstruction where MILS is required to be adopted after assessment, be prepared for the need to gently move the airway away from the neutral position to facilitate a view of the glottis or the offending obstruction.

INTRAVENOUS ACCESS
Goal: |
Intravenous (IV) cannulation provides
access to the circulation to administer drug therapy or fluids. (IV access is an invasive procedure and appropriate consideration must be given to its requirement in the pre-hospital setting). |
|
INTRAVENOUS ACCESS
Indications: |
The administration of a drug or fluid.
|
|
INTRAVENOUS ACCESS
Contraindications: |
Whenever possible avoid sites of
burn, infection or localised cellulitis. |
|
INTRAVENOUS ACCESS
Precautions / Complications: |
Air embolus
Arterial puncture Cannula shear or breakage Drug/fluid extravasion Haematoma or haemorrhage from the site Infection or phlebitis Irritation to the vein wall Nerve damage Vasovagal syncope |
|
INTRAVENOUS ACCESS
Additional Information: |
IV access should only be implemented
after all basic cares. The number of cannulation attempts should reflect the urgency of the case. The following sites are not to be used for IV access: Lower limbs when pelvis, abdominal or thoracic trauma is suspected Distal to a complex limb injury Limb with a fistula present An area of phlebitis or cellulitis When a limb has potential or existing lymphodema (e.g. the same side as lymph node clearance) |
|
INTRAVENOUS ACCESS
Clinical Judgement Issues: |
Use of volume expansion in
uncontrolled haemorrhage (without a concurrent traumatic brain injury) may be associated with poor outcomes. Paramedics are to administer the minimum amount of IV fluid required to maintain a radial pulse. Hypotension with a concurrent traumatic brain injury is associated with poor outcomes. Paramedics are to administer the minimum amount of IV fluid required to maintain a systolic BP of 100 – 120 mmHg (adult). Excessive fluid infusion may lead to neurogenic pulmonary oedema in the spinal cord injured patient. Too rapid infusion of fluids in a patient without a fluid deficit, or with underlying cardiac problems, may cause pulmonary oedema and congestive heart failure. Benefits of fluid infusion must be carefully analysed against concerns with the patient’s overall condition. A gentle fluid challenge may be considered for patients with suspected right ventricular infarct (following 12- Lead ECG acquisition with V4R) and no signs of left ventricular failure (e.g. pulmonary oedema). Adult patients must be reassessed after every 250 – 500 mL of fluid administration. Paediatric patients must be reassessed after every 10 mL/kg of fluid administration. IV fluids should not be administered to patients with significant facial, neck or upper chest burns with high potential for airway or ventilation compromise before the airway is formally secured at hospital. Large amounts of fluids increase the risk of interstitial oedema and tissue swelling, potentially increasing the difficulty of endotracheal intubation. |

BREECH BIRTH
Goal: |
To safely and effectively manage a
breech birth |
|
BREECH BIRTH
Indications: |
To assist a labouring woman in the
delivery of her child when the child presents in a breech position |
|
BREECH BIRTH
Contraindications: |
Nil in this setting
|
|
BREECH BIRTH
Precautions / Complications: |
Failure to deliver
Pain Prolapsed cord Shoulder dystocia (refer to CPP) Head entrapment Meconium aspiration Post-partun haemorrhage (refer to CPG) Inversion of the uterus (refer to CPG) Complications of breech delivery can lead to foetal distress and hypoxia potentiating a compromised neonate. Preparation for neonate resuscitation should be made at the earliest sign of breech presentation. Consideration should be given to early activation of ICP/obstetric retrieval team backup. Ensure an aseptic technique with appropriate infection control measures to be taken at all times |

BREECH BIRTH
Clinical Judgement Issues: |
The main categories of breech births
include: Frank breech – the foetus’s bottom comes first, with the legs flexed at the hips and extended at the knees, placing the feet near the ears). Most breech babies (65-70%) are in the Frank breech position. Complete breech – here the hips and knees are flexed so that the foetus is sitting cross-legged, with the feet beside the bottom. Footling breech – one or both feet come first, with the bottom at a higher position. This is rare at term, but relatively common with premature babies. Kneeling breech – the foetus is in a kneeling position, with one or both legs extended at the hips and flexed at the knees. This is extremely rare and often grouped with footling to form the category “incomplete breech”. Foetal trauma is a significant risk if the required procedures are not performed gently and without undue force (e.g. limb fractures and internal injuries) The cord can become nipped under the pubic arch. The procedure here is to gently pull the cord around to the perineum to release any potential pressure. A breech presentation can occur in the setting of twins. If there is no antenatal history, be alert for a second foetus. Head entrapment is a critical problem because the largest part of the infant (the head) delivers last, and the cervix may not be fully dilated. Remember to collect and consider carefully all antenatal history that the patient is able to supply. |

12-LEAD ECG ACQUISITION
Goal: |
The 12-lead electrocardiogram (ECG) is
used to detect many conditions affecting the heart, underlying myocardial ischaemia, dysrrhythmias, drug toxicity and electrolyte imbalances. Use in the pre-hospital setting is paramount to the diagnosis and treatment of STEMI, (via the QAS cardiac reperfusion strategy). |
|
12-LEAD ECG ACQUISITION
Indications: |
To aid in the identification of:
myocardial ischaemia or infarct rhythm and conduction disturbance electrolyte imbalance hypertrophy of the heart drug toxicity |
|
12-LEAD ECG ACQUISITION
Contraindications: |
Nil in this setting.
|
|
12-LEAD ECG ACQUISITION
Precautions / Complications: |
Nil in this setting.
|
|
12-LEAD ECG ACQUISITION
Clinical Judgement Issues: |
To ensure the 12-Lead ECG printout is of
diagnostic quality check that: ECG frequency is set at 0.05 – 40 Hz, and Paper speed is set at 25 mm/sec |
|
12-LEAD ECG ACQUISITION
Additional Information: |
The 12-Lead ECG should be acquired
as part of an early secondary assessment of the patient, especially in the setting of suspected cardiac ischaemia or infarct. Electrodes should remain in their original placement throughout management to facilitate the comparison of serial 12-Lead ECGs. |
