When is fiberoptic intubation used?
Fiberoptic intubation (FOI) is an effective technique for establishing airway access in patients with both anticipated and unanticipated difficult airways. First described in the late 1960s, this approach can facilitate airway management in a variety of clinical scenarios given proper patient preparation and technique.
What is nasal fiberoptic intubation?
Awake fiberoptic nasotracheal intubation is a useful technique, especially in patients with airway obstruction. It must not only provide sufficient anesthesia, but also maintain spontaneous breathing.
When do you do awake intubation?
In general, awake intubation should be preferred if:
- airway does not need to be immediately secured (i.e. sufficient time for preparation)
- significant risk of a difficult airway.
- low risk of vomiting.
- compliant patient.
- endotracheal intubation via the nasal or oral route is feasible.
Why are patients intubated during surgery?
Why You Might Need It. The drugs that put you to “sleep” during surgery (general anesthesia) may also hold down your breathing. Intubation lets a machine breathe for you. That’s why your anesthesiologist (the doctor who puts you to sleep for surgery) might intubate you.
How do you do nasal fiberoptic intubation?
The applicators are gently inserted into each nostril and gently advanced until they reach the posterior wall of the nasopharynx. Alternatively, the solution can be dripped in using a 20 gauge intravenous catheter or sprayed using an atomizer. It is advisable to prepare both nares.
How do you awaken fiberoptic intubation?
When fibreoptic intubation is performed in the awake state, the operator can use a technique of “spray as you go” through the suction channel. A continuous flow of oxygen (2–3 litres per min) helps to maintain oxygenation while at the same time clears secretions away from the optical system of the fibrescope.
Why is intubation done?
Intubation is a procedure that can help save a life when someone can’t breathe. A healthcare provider uses a laryngoscope to guide an endotracheal tube (ETT) into the mouth or nose, voicebox, then trachea. The tube keeps the airway open so air can get to the lungs.
What is the criteria for intubation?
Indications for intubation to secure the airway include respiratory failure (hypoxic or hypercapnic), apnea, a reduced level of consciousness (sometimes stated as GCS less than or equal to 8), rapid change of mental status, airway injury or impending airway compromise, high risk for aspiration, or ‘trauma to the box ( …
What’s the purpose of intubation?
What are the parameters that indicate the need for intubation?
What is Fibre optic bronchoscope?
Flexible fiberoptic bronchoscopy (FFB) is an invasive procedure that has been used for a long time for diagnostic and therapeutic purposes. It contains a light source, fiber optics, and a camera that allows direct visualization of the upper and lower airways [1].
How do you anesthetize airway for awake fiberoptic intubation?
These nerves need to be blocked to allow for awake nasal fiber-optic intubation. These nerves are usually blocked by the topical application of local anesthetic to the nasal passages, usually by inhalation, spray topicalization, or the application of cotton applicators soaked in anesthetic.
What medications are used for intubation?
[4] Common sedative agents used during rapid sequence intubation include etomidate, ketamine, and propofol. Commonly used neuromuscular blocking agents are succinylcholine and rocuronium. Certain induction agents and paralytic drugs may be more beneficial than others in certain clinical situations.
