Comparative Study[Comparative value of clinical signs of difficult tracheal intubation in women].
A prospective study was designed to compare the value of clinical signs aimed to predict difficult intubation in women. A group of 663 women, scheduled for elective surgery, were assessed by an anaesthetist at the preanaesthetic visit. Following parameters were assessed: the degree of mouth opening, the chin-hyoid bone and the chin-thyroid cartilage distances, dental and facial abnormalities, age, weight. ⋯ Other clinical criteria (mouth opening, the chin-hyoid bone distance) had a lower sensitivities, but seemed more specific. Multivariate analysis showed that specificity could be improved (0.84) if the distance between the upper and lower incisor teeth (mouth opening) was associated with Mallampati's rank, without any loss in sensitivity. A simple chart is proposed to assess the risk of difficult intubation.

Comparative Study
Incidence of pulmonary aspiration in intubated patients receiving enteral nutrition through wide- and narrow-bore nasogastric feeding tubes.
A descriptive study was performed to compare the incidence of pulmonary aspiration in 25 critically ill patients who had endotracheal tubes in place and were receiving enteral nutrition through a narrow-bore nasogastric tube (n = 10) or a wide-bore nasogastric tube (n = 15). Results of chi-square analysis of this comparison were not significant, p less than 0.05. Aspiration occurred in one subject. ⋯ The number of checks for residual feeding was found to be significantly greater in the wide-bore tube group. A comparison of the assessment of nasogastric tube placement on x-ray examination showed that tube placement was reported on x-ray results with more frequency in the wide-bore group. Questions are raised by these observations regarding the use of narrow-bore tubes in the critically ill population with endotracheal tubes in place.

The Laryngeal Mask (LM) can be used to intubate patients in whom conventional direct laryngoscopy is difficult. Tracheal intubation can be achieved using the LM alone but the use of a fibre-optic laryngoscope increases the chances of success.

Case Reports[Surgical repair of a tracheal tear caused by an endotracheal tube via dual surgical approach].
We report a case of large tracheal (cervical thoracic) rupture after using an endotracheal tube, which needed to be repaired via a double surgical approach: cervicotomy and right thoracotomy. To our knowledge, no similar cases have been previously reported in the medial literature.
