Mask ventilation (MV) is a pivotal procedure used to deliver oxygen during the induction of general anesthesia before a secure airway with a tracheal tube or supraglottic airway device can be established. Difficult mask ventilation (DMV) may cause hypoxic tissue injury resulting in morbidity and mortality related to anesthesia.

Jul 01 2012· To overcome this problem we used an adult face mask for induction of anesthesia. This bigger mask enclosed the communicating wound and prevented the leak of anesthetic gases. Use of the pediatric mask for ventilation in adults has been described.[45] But we are not aware of reports of use of the adult face mask for pediatric cases.

although some of anesthesiologists may choose no positive-pressure ventilation before intubation they must prepare for failure of the first intubation attempt and therefore facemask ventilation because oxygenation with facemask ventilation is the first priority in case of desaturation knowing the risk of regurgitation. 2 a higher inspiratory …

Jan 01 2017· Depending on upper airway patency during anesthesia induction tidal volume achieved by mask ventilation may vary. In 80 adult patients undergoing general anesthesia the authors tested a hypothesis that tidal volume during mask ventilation is smaller in patients with sleep-disordered breathing priorly defined as apnea hypopnea index greater than 5 per …

Induction of anesthesia and MV evaluation. An anesthesiologist with more than 3 years of experience was assigned to airway management. During induction of anesthesia the patient’s head and neck were placed in a sniffing position. Preoxygenation of each patient was performed for 4 min by mask with 100% O 2.

In such cases induction of anesthesia while maintaining spontaneous ventilation through standard or Patil''s endoscopic facemask could be performed to facilitate fiberoptic laryngoscopy.[4] But the situations where facemask could not be applied properly pose a challenge to the anesthesiologist for smooth induction and endotracheal intubation.
