The investigators hypothesize nasal mask ventilation may reduce the incidence of difficult mask ventilation during the induction of general anesthesia by: 1) producing a better seal than full face mask, and 2)establishing a greater airway patency and more effectively ventilate than full face mask ventilation.

MASK ventilation is an essential component of airway management either as the primary technique during general anesthesia or only during the induction period. In each scenario, upper airway obstruction (UAO) is frequently encountered. 1 To overcome UAO, an oral or nasal airway device is frequently inserted.

Conclusions: The nasal route was more effective than the combined oral-nasal route (the usual mode of full facemask ventilation) in ventilating apneic, non-paralyzed, adult subjects during induction of general anesthesia. We suggest that nasal mask ventilation, rather than combined oral-nasal mask ventilation be used during induction of anesthesia.

If ventilation is difficult after inserting a King LT airway, you should: Answers: A. deflate both of the cuffs, withdraw the device 2 cm, and reattempt ventilation. B. gently withdraw the device, without deflating the cuffs, until ventilation is easier. C. attach a manually triggered ventilator and observe for adequate chest rise. D.

BACKGROUND: During induction of general anesthesia, proper mask ventilation is crucial for supplying sufficient oxygen to unconscious patients. Midazolam has a relaxing effect on airway muscles. We hypothesized that sedative premedication with midazolam would facilitate mask ventilation during anesthetic induction.

Given the potential for a difficult airway, nasal cannula (NC) was applied at 1.5 L/min immediately prior to mask general induction with 8% sevoflurane under spontaneous ventilation. Mask ventilation was initiated once the patient’s respiratory effort diminished, and it was discontinued right before intubation was attempted.

The process of inserting an ET tube into the airways of the patient is known as endotracheal intubation. The ET tube comes in various types and sizes. The size of the ET tube can be determined by the inner diameter (ID). For example, if the ID is 8 mm, the tube size is also 8. Also, ET tubes can either be cuffed or uncuffed.

01-12-2017· Inhalation induction has historically been the technique of choice for the management of an obstructed airway and was advocated in previous versions of this publication.14 The perceived advantage of an inhalation induction is that, by maintaining spontaneous ventilation and hence reversibility, there may be the option of waking the patient …

After standardized induction of general anesthesia and muscle paralysis, a tight-fitting face mask was applied to each patient, and tidal volume was measured by the anesthesia machine during pressure-controlled ventilation (10, 15, 20 cm H2O; 8 breaths·min-1; inspiratory:expiratory ratio 1:2).

Recently, the investigators demonstrated that nasal route ventilation is superior to the nasal-oral combined ventilation in the absence of jaw thrust and chin up maneuvers.
