The failure rate of blind intubation
is high, and above all, blind intubation
may cause tissue damage.
However, it is criticized as blind intubation
through it has the potential for causing arytenoid trauma or oesophageal placement.
While the first patient was intubated on second attempt with blind intubation
technique the latter was intubated on the third attempt without usage of any alternative device.
There has however, been a case report of a fatal oesophageal rupture with blind intubation through an intubating laryngeal mask (18).
Pharyngeal wall perforation--an unusual complication of blind intubation with a gum elastic bougie.
For the severely retrognathic infant or child, airway management frequently involves blind intubation or tracheostomy under local anesthesia.
Blind intubation through the laryngeal mask airway for management of the difficult airway in infants.
via the ILMA: What about accidental oesophageal intubation?
They also include blind intubation
(oral or nasal) and fibreoptic intubation in their list of techniques for difficult airway management.
Joo and Rose(6) reported that the haemodynamic response to blind and fibreoptic-guided intubation with the ILMA was less than the response to conventional laryngoscope-guided tracheal intubation whereas Kihara et al(7) observed that blind intubation through an ILMA had no advantage over laryngoscope-guided tracheal intubation in patients with normal airways.
The possible cause for the lesser increase in IOP and blood pressure in ILMA-guided blind intubation may be lesser adrenergic stimulation at supraglottic level, and also at subglottic level due to the soft tip and well-lubricated silicon tube.
After three failed attempts, or if the best quality of laryngeal view remained poor, one blind intubation
attempt was allowed in the CTrach[TM] group.
