In our opinion, when risk factors for RE are associated with difficult airway management and/or prolonged intubation, a conservative approach consisting of otolaryngology consultation, fiberoptic examination, or a neck computed tomography scan may be undertaken for a safe airway assessment and detection of a potentially critical obstruction.
Because the airway of a child is narrow, a small amount of glottic or tracheal swelling can produce critical obstruction.
If such an obstacle exists (typically, a safety barrier), its height should not exceed the critical obstruction's height presented in Table 2.
23 It is postulated that infection precipitates inflammation by induction of a prothrombotic state or autoimmune reactions in already-diseased coronary vessels, causing critical obstruction.
Since our patient did not present stridor before intubation, the additional laryngeal edema due to airway management, which would have not been responsible for post-extubation failure in normal conditions, contributed to reaching the critical obstruction of airways.
However, in a few studies minimal coronary artery disease, like atheromatous plaque without critical obstructions, is included as "normal coronary angiogram" [ 18, 22, 56].
Following a critical incident of HME obstruction due to waterlogging on our ICU we realised that HH and HME may be used together inadvertently.
Martha Stewart's attempt to erase a critical email message is classic obstruction (she ordered it restored, so she wasn't charged).
We speculate that vascular calcifications in the area targeted by shock waves played a critical role in renal artery obstruction in the present case.
Among these Th2 cytokines, IL-13 has been demonstrated to be a critical mediator in the mucus obstruction phenotype evidenced in the mouse model of allergic asthma [ 13].
