4th July [26th-1st] Flashcards
What does RSI stand for in terms of intubation?
Rapid Sequence induction
Steps in RSI
- Pre-oxygenation
- Drugs [relaxing the airway]
- Cricoid compression
- Suction
- Laryngoscope
- Endotracheal tube insertion
What happens before RSI?
- see if patient conscious
- call for help/anaesthetist
- open airway and examine with head tilt
What to do if can’t head tilt patient [due to e.g. neck brace]?
- chin thrust
What happens during the pre-oxygenation stage of intubation?
- Try smaller gadelle [oropharygeal airway] or nasopharyngeal airway
- Or try a IGEL [supraglottic airway]
- Can keep these in place, then put on mask with the squeezable bag [bag mask ventilator]
How to check the size of oro/nasopharyngeal airway?
Soft on soft: soft palate follow round to corner of mandible to see correct size
Hard on hard: hard palate follow round top of teeth incisor to bottom corner jaw
How do you hold the ventilator?
C and E formed with hand, hold close to patient mouth
Drugs given to patient in RSI
Muscle relaxants -> like propafol and rockiuranium or something?
RSI traditionally involves preoxygenating the lungs with a tightly fitting oxygen mask, followed by the sequential administration of an intravenous sleep-inducing agent and a rapidly acting neuromuscular-blocking drug, such as rocuronium, succinylcholine, or cisatracurium besilate, before intubation of the trachea.
Pneumonic for difficult to access airways?
LEMON
LEMON stand for?
Look externally Evaluate 332 Mallampati Obstruction scores Neck mobility
What’s a mallampati score?
Predict difficult patients for intubation -> over 2-4 difficult
Signs that the endotracheal tube is in place correctly
- CO2 levels?
- O2 saturation
- Vision: see if it went in correctly
- Chest rising equally on both sides
- hm
GCS of someone with a decreased level of consciousness classed to be in a stupor/coma
GCS of 8
Indications for intubation
- Depressed level of consciousness
- Hypoxemia
- Airway obstruction
- Manipulation of airway [e.g. bronchoscopy]
- Newborn
What may be used to help insert intubation equipment into the right place?
A stylet: malleable long wire
When are cricothyromoties indicated?
A cricothyrotomy is an incision made through the skin and cricothyroid membrane to establish a patent airway during certain life-threatening situations, such as airway obstruction by a foreign body, angioedema, or massive facial trauma.[53] A cricothyrotomy is nearly always performed as a last resort in cases where orotracheal and nasotracheal intubation are impossible or contraindicated. Cricothyrotomy is easier and quicker to perform than tracheotomy, does not require manipulation of the cervical spine and is associated with fewer complications.
When are tracheostomies indicated?
In the acute setting, indications for tracheotomy are similar to those for cricothyrotomy. In the chronic setting, indications for tracheotomy include the need for long-term mechanical ventilation and removal of tracheal secretions (e.g., comatose patients, or extensive surgery involving the head and neck)
Risks of tracheostomy
In the acute setting, indications for tracheotomy are similar to those for cricothyrotomy. In the chronic setting, indications for tracheotomy include the need for long-term mechanical ventilation and removal of tracheal secretions (e.g., comatose patients, or extensive surgery involving the head and neck).
Gold standard for confirmation of tube placement
Waveform capnography has emerged as the gold standard for the confirmation of tube placement within the trachea.
List examples of predicting difficulty for intubation
the range of motion of the cervical spine: the subject should be able to tilt the head back and then forward so that the chin touches the chest.
the range of motion of the jaw (the temporomandibular joint): three of the subject’s fingers should be able to fit between the upper and lower incisors.
the size and shape of the upper jaw and lower jaw, looking especially for problems such as maxillary hypoplasia (an underdeveloped upper jaw), micrognathia (an abnormally small jaw), or retrognathia (misalignment of the upper and lower jaw).
the thyromental distance: three of the subject’s fingers should be able to fit between the Adam’s apple and the chin.
the size and shape of the tongue and palate relative to the size of the mouth.
the teeth, especially noting the presence of prominent maxillary incisors, any loose or damaged teeth, or crowns.
