How do you manage a difficult airway?
Noninvasive interventions intended to manage a difficult airway include, but are not limited to: (1) awake intubation, (2) video-assisted laryngoscopy, (3) intubating stylets or tube-changers, (4) SGA for ventilation (e.g., LMA, laryngeal tube), (5) SGA for intubation (e.g., ILMA), (6) rigid laryngoscopic blades of …
What is difficult airway algorithm?
The Difficult Airway Algorithm of the American Society of Anesthesiologists (ASA) was developed to guide clinicians in the management of the patient who is either predicted to have a difficult airway or whose airway cannot be adequately managed after induction of anesthesia (1).
What is the gold standard for airway management?
Historically endotracheal intubation has been considered the gold standard for airway management.
How will you perform rapid sequence induction?
It involves loss of consciousness during cricoid pressure followed by intubation without face mask ventilation. The aim is to intubate the trachea as quickly and as safely as possible. This technique is employed daily during emergency surgery.
What is most likely to predict a difficult airway?
TAS was the most significant predictor of difficult endotracheal intubation. If TAS was greater than 6 points, the risk of difficult endotracheal intubation was 13.57 times as great (95% CI = 2.99-61.54, P < 0.05, Table 5).
Which Mallampati score would predict a very difficult intubation?
Mallampati scores III and IV were considered as predictors for difficult intubations. Among 22 patients with Mallampati scores of III or IV using the MMT-TP and 41 patients with Mallampati scores of III or IV using the MMT-NTP, only 6 and 9 patients, respectively, were truly difficult to intubate.
Is there a gold standard for management of the difficult airway?
No other specialties involved in airway management have produced their own guidelines for difficult airway management based on a systematic review of the literature. No evidence exists to support one set of guidelines over another as a gold standard.
When does EMS intubate?
Field intubation should be used in patients that have lost control or have an impending loss of their airway, or patients that require increased ventilatory support that cannot be maintained through BVM ventilation and the use of airway adjuncts.
What are the 7 steps of rapid sequence intubation?
Steps of RSI (7 Ps)
- Preparation & Plan.
- Paralysis and induction.
- Protection and positioning.
- Placement with proof.
- Post-intubation management.
Do you give etomidate before succinylcholine?
Patients receiving etomidate generally return to baseline cognitive and neuromuscular status within five minutes. If the patient is unable to be ventilated and succinylcholine is available, it should be administered immediately at the RSI dose of 1.5mg/kg.
How do you perform a Cricothyrotomy?
The patient lies supine with the neck extended. After sterile preparation, the larynx is grasped with one hand while a blade is used to incise the skin, subcutaneous tissue, and cricothyroid membrane precisely in the midline, accessing the trachea. A hollow tube is used to keep the airway open.
What is front of neck access?
Emergency front of neck access (eFONA) can be defined as the securing of a patent airway via the anterior neck to facilitate emergency alveolar oxygenation. eFONA is the final lifesaving step in airway management to reverse hypoxia and prevent resulting brain injury, cardiac arrest, and death.
How do you do Sellick maneuver?
The Sellick Maneuver is performed by applying gentle pressure to the anterior neck (in a posterior direction) at the level of the Cricoid Cartilage. The Maneuver is most often used to help align the airway structures during endotracheal intubation.
What drugs are used in rapid sequence intubation?
 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.
What is the 3 3 2 rule anesthesia?
(A) More than 3 fingers between the open incisors, indicating patient’s mouth opens adequately to permit the laryngoscope to reach the airway; (B) more than 3 fingers along from mentum to hyoid bone, which indicates enough space for intubation; (C)
What is the 332 rule in intubation?
The 3-3-1 rule is defined as an interincisor distance (IID) less than three fingers, a hyoid-mental distance (HMD) less than three fingers, and a hyoid-thyroid cartilage distance (HTD) less than one finger.
What does Mallampati 4 mean?
A Mallampati score of III or IV is typically indicative of a higher rate of obstruction in airway as a result of enlarged tonsils or adenoids and poor Myofunctional activity (swallowing pattern and tongue position at rest) and tongue-tie.
Is there a universal algorithm for difficult airway management situations?
The frequency of algorithm publication has increased recently, yet adherence and implementation outcome data remain limited. Our results highlight the lack of a single algorithm that is universally endorsed, recognised and applicable to all difficult airway management situations.
How is the Das algorithm used in airway management?
Using this approach, the DAS algorithm is used to plan the techniques to be employed during airway management, which should be voiced to the team before induction of anaesthesia in the Plan A,B,C,D format.
Does uniform application of a difficult airway algorithm reduce hypoxic brain damage?
Uniform application of a difficult airway algorithm might decrease the incidence of hypoxic brain damage during anesthesia induction
Are there any guidelines for airway management in the UK?
The Difficult Airway Society in the UK has comprehensive guidelines for airway management, including multiple algorithms. The integrated algorithm can be downloaded here (pdf).
