To the Editor:
Brodsky, et al (1) found a positive relationship between neck circumference and the difficulty of endotracheal intubation in morbidly obese patients. However, they could not demonstrate any relationship between a history of sleep apnea syndrome (SAS) and the difficulty of intubation reported in previous studies (2,3). The lack of correlation may be because the diagnosis of SAS was apparently not confirmed by polysomnography. Indeed, history suggestive of SAS, per se, is not sensitive enough to make the diagnostic of SAS (4,5). It is possible that some of their patients did not have SAS, thus weakening the correlation.
Anecdotally, the two lines correlating in Table 2, the problematic intubation column, and the number of patients with or without SAS (Yes/No) should be reversed.
