There are a number of ways to grade the airway (such as the Mallampati score, thyromental distance, or Bellhouse-Doré score). An objective evaluation of the. Bellhouse and Dore11 have demonstrated that AO joint extension can be easily measured clinically, and that the measurement is highly predictive of the ease of . Bellhouse-Dore score). • Preparation for airway disaster must be in place for patients with high risk for difficult airway. • Emergency equipment must be available.

The patient had been administered treatment with radiotherapy to this site in without tumor shrinkage of the tumor.

An objective evaluation of the airway using a valid method is more important than the choice of method itself. The details for each of the safety steps are as follows: Difficult airway management-novel use for the theatre register. At this point this phase is completed and bdllhouse team may proceed with anaesthetic induction. If the airway evaluation indicates a high risk for a difficult airway such as a Mallampati score of 3 or 4the anaesthesia team must prepare against an airway disaster.

The Checklist coordinator should verbally confirm that the anaesthesia team has objectively assessed whether the patient has a difficult airway.

National Center for Biotechnology InformationU. At National Institute of Cancerology in Mexico City difficult airway patients is a very common finding, bimanual manipulation or optimal external laryngeal pressure recommended by certain doree at the thyroid and cricoid cartilage level and cited by some authors for the area of the neck, as well as required pressure, cannot be performed because of the large tumors that we have.

The details for each of the safety steps are as follows:. Difficult laryngoscopy made easy with a BURP. Ann Emerg MedThe Checklist coordinator confirms that a pulse oximeter has been placed on the patient and is functioning correctly before induction of anaesthesia.

Clear Turn Off Turn On. The risk can be reduced by modifying the anaesthesia plan, for example using rapid induction techniques and enlisting the help of an assistant to provide cricoid pressure during induction. An audible system should be used to alert the team to the patient’s pulse rate and oxygen saturation. Figure 2 Figure 2- Magnetic resonance reconstruction evidencing involvement of the maxilla.


Before induction of anaesthesia. We present the case of an year-old male with tuberous sclerosis who required intubation because of facial deformity secondary to progressive tumor growth and debunking was planned, droe to classic maneuvers are discussed.

Therefore, if the anaesthetist does not know what the risk of major blood loss is for the case, he or she should discuss the risk with the surgeon before the operation begins.

This will include, at a minimum, adjusting the approach to anaesthesia for example, using a regional anaesthetic, if possible and having emergency equipment accessible. Please review our privacy policy. World Health Organization; There are simple and non-invasive scales for evaluation for suspicion of the condition, including the following: J Clin Anesth ,8: During surgical procedures of head and neck lesions, management of the airway is always a problem and anticipation of difficulties in intubation have to observed, alternative maneuvers for intubation may be necessary.

When confirmation by the patient is impossible, such as in the case of children or incapacitated patients, a guardian or family member can assume this role. Head and neck elevation beyond the sniffing position improves laryngeal view in cases of difficult direct laryngoscopy. Adequate appraisal of the patient is necessary, because it aids in anticipating difficult airway. If the patient has symptomatic active reflux or a full stomach, the anaesthetist must prepare for the possibility of aspiration.

Other titles in this collection. Background One of the most important issues and concerns during surgical procedures of head and neck lesions is the problematic of management of the airway, defining difficult airway as the clinical situation in which there exists a difficulty for ventilation with mask, difficulty for endotracheal intubation, or both, and difficult intubation, such as endotracheal catheter placement that requires more than three attempts or more than 10 minutes to perform intubation 1.

Pre-anesthetic evaluation scores for difficult airway were as follows: The following are recommended within the management guides for difficult airway approach clinical indications: At the end of surgery, extubation was conducted with the patient awake, without complications.

If no functioning pulse oximeter is available, the surgeon and anaesthetist must evaluate the acuity of the patient’s condition and consider postponing surgery until appropriate steps are taken to secure one. Safe Surgery Saves Lives. Surgeons may not consistently communicate the risk of blood loss to anaesthesia and nursing staff. It requires the presence of the anaesthetist and nursing personnel at the very least. Discussion Adequate appraisal of the patient is necessary, because it aids in anticipating difficult airway.


Ideally the pulse oximetry reading should be visible to the operating team. Combinations of maneuvers have been recommended, including head elevation and external laryngeal pressure to improve laryngeal visualization 11,12BURP maneuver, and mandibular advancement, which are frequently helpful in fiber optics-enhanced intubation Improved visualization of laryngeal structures has been shown, and laryngeal approach was permitted 6,7, For a patient recognized as having a difficult airway or being at risk for aspiration, induction of anaesthesia should begin only when the anaesthetist confirms that he or she has adequate equipment and assistance present at the bedside.

Before induction of anaesthesia – WHO Guidelines for Safe Surgery – NCBI Bookshelf

Positioning of the head has also been cited as determinant during airway approach; diverse authors, such as H. Difficult tracheal intubation in obstetrics.

The Checklist coordinator completes this next step by asking the anaesthetist to verify completion of an anaesthesia safety check, understood to be a formal inspection of the anaesthetic equipment, breathing circuit, medications and patient’s anaesthetic risk before each case.

Does the patient have a known allergy?

Figure 1 Figure 1- Facial deformity and location of larynx. Close Enter the site. Thus, it is necessary to improve this external optimal laryngeal manipulation. We described herein the approach for accessing the airway in a patient with a diagnosis of tuberous sclerosis and maxillary tumor in left hemiface with extensive deformity that encompasses nasal septum and mouth.

Some authors have subdivided visualization into three degrees: During the surgical procedure, the patient was hemodynamically stable with adequate ventilatory parameters Figure 4. Br J AnaesthIf the coordinator knows of an allergy that the anaesthetist is not aware of, this information should be communicated. These scales possess high sensitivity, but low specificity and low predictive value; thus, maneuvers for facilitating laryngeal doore and with this, intubation, are important.
