09.08.2016· Rapid sequence intubation (RSI) is the preferred method of emergency airway management. It involves the near simultaneous administration of fast-acting induction and neuromuscular blocking agents to achieve optimal intubating conditions without the need for bag-mask ventilation. The following discussion of orotracheal intubation refers to RSI. Techniques …

ANESTHESIOLOGISTS perform mask ventilation (MV) with proper airway maintenance maneuvers during induction of general anesthesia. Proper oxygenation is only secured by the MV when tracheal intubation is difficult or impossible. Despite the clinical significance, MV technique has changed little in contrast to significant improvement of tracheal intubation …

anesthetized to allow for intubation, a mask can be used to administer more anesthetic gas to deepen the anesthetic plane. • Compared to the chamber, the gas mask method exposes the anesthetist to less anesthetic. • When using mask induction, start the vaporizer setting at 0.5% and increase in 0.5% increments every 30 seconds until the patient is sedate to reduce the …

Anesthesia was induced by mask inhalation of high concentration of sevoflurane (up to 5%) in 100% oxygen through a Bain circuit. Spontaneous breathing was sustained. When relaxation for intubation was adequate, a size-6 endotracheal tube was passed through an extremely swollen arytenoid region and edematous epiglottis oratracheally. After taking blood and throat culture …

o After induction of anesthesia, mask ventilation is avoided o CP: Personnel with experience (or with clear instructions) will apply firm pressure with the index finger and thumb on 1st tracheal ring (cricoid) and will continue until ETT placement is confirmed (bilateral auscultation). • Modified RSII: o Mask ventilation after induction: when interruption of ventilation is expected to result ...

Anesthesia was induced with fentanyl 2 µg/kg, propofol 2 mg/kg, and rocuronium 0.6 mg/kg. Mask ventilation was initiated using 100% Oxygen and after ensuring full muscle relaxation as assessed by a nerve stimulator, orotracheal intubation was performed using the selected intubation device for each group. Anesthesia was maintained with ...

Conclusions: The induction of anesthesia to loss of lid reflex in young non-premedicated adults approaches the speed of intravenous induction techniques. No untoward airway responses were noted during mask induction of anesthesia with a three-breath technique. In response to intubation, no adverse airway responses, including jaw tightness, laryngospasm, and …

11.09.2019· To determine whether bag-mask ventilation between induction of anaesthesia and tracheal intubation in children with post-tonsillectomy bleeding reduces the incidence of hypoxaemia and difficult direct laryngoscopy without increasing perioperative respiratory complications. Methods. Medical records, anaesthesia protocols and vital sign data were …

Prompt full-scale resuscitation was required in both cases due to asystole that developed immediately after induction of anesthesia and tracheal intubation. In one case, cardiac activity was successfully recovered by complex resuscitation with the emergency drainage of the cerebral ventricles. The possible causes of complications and preventive measures were discussed. …

Unexpected lingual tonsillar hypertrophy can cause both ventilation and tracheal intubation difficult, and neither the laryngeal mask nor intubating larynGEal mask may be helpful in the circumstances. Purpose: To report unexpected failed tracheal intubation using a laryngoscope and an intubating laryngeal mask, and difficult ventilation via a facemask, laryngeal mask and …

25.07.2018· Tracheal intubation is generally used in patients unconscious or with respiratory failure to keep the airway open and to ensure ventilation of the patient. Endotracheal intubation is also performed in cases where general anesthesia will be applied for the operation. Endotracheal intubation is performed in various situations such as failure of noninvasive ventilation in …
