A Novel Rescue Technique for Difficult Intubation and Difficult Ventilation
Published on: January 17, 2011
Laryngeal mask insertion with a laryngoscope in paediatric patients
Purpose:
To assess epiglottic position after laryngeal mask airway (LMA) insertion with or without the use of a laryngoscope.
Methods:
A double-blind randomized study. In 48 children an LMA (#2 for 6-20 kg, #2.5 for 20-30 kg) was inserted either blindly or with the help of a laryngoscope and its position assessed using fibreoptic endoscopy.
Results:
An unobstructed view of the glottis, as assessed by fibrescope, was observed in 10 of 25 patients in the laryngoscope group, but only in 1 of 22 patients in the blind insertion group (P = 0.005).
Conclusion:
This technique offers an alternative when the standard technique has failed, or when LMA insertion precedes bronchoscopy or intubation via the laryngeal mask.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
