Case Reports[Tooth injuries during general anesthesia, oral endoscopy and vibro-massage].
It is generally recognized that dental injury during and after tracheal intubation is a significant problem. Damage may occur during oro-tracheal intubation, oral endoscopy or seismotherapy. The incidence was reported in a study conducted in the contentious department of Lyon hospitals, in France, from 1978 to 1988. ⋯ Some of the most recent development in dental therapy such as the butterfly bridge, titanium implants and porcelain laminate veneers are described. Tooth protective guards must be put into widespread use. Legal implications of dental lesions occurring during oro-tracheal intubation, oral endoscopy or seismotherapy are presented.

Randomized Controlled Trial Comparative Study Clinical TrialTracheal soiling with blood during intranasal surgery--comparison of two endotracheal tubes.
Sixty adult patients, ASA Classes I & II, were involved in a study to compare the effectiveness of Mallinckrodt Hi-Lo-Evac tube and Portex blue line tube in preventing soiling of the lower airways during intranasal surgery. The Hi-Lo-Evac tube with and without pack was significantly more effective than the Portex tube with pharyngeal pack (P less than 0.002) and (P less than 0.01 respectively). ⋯ The more effective protection of the lower airways by the Hi-Lo-Evac tube is attributed to the facility of subglottic aspiration during surgery. It is suggested that the Hi-Lo-Evac tube could be used with safety during intranasal surgery in order to reduce postoperative morbidity associated with the use of pharyngeal pack.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial
Priming of pancuronium with magnesium.
Magnesium inhibits the release of acetylcholine from the motor nerve terminal and thus potentiates the action of the non-depolarizing neuromuscular blocking drugs. We have examined the possibility that this effect might enhance the speed of onset of non-depolarizing block with pancuronium. ⋯ Tracheal intubation was performed after 97.8 (22.5) s in the magnesium group and in 121.0 (37.5) s in the control group (ns). It is concluded that pretreatment with magnesium does not usefully increase the speed of onset of action of pancuronium.

[Sinusitis in long-term intubated, intensive care patients: nasal versus oral intubation].
Discussion of paranasal sinusitis as a nosocomial infection in the mechanically ventilated intensive care (ICU) patient has recently been intensified. Some authors have emphasized nasotracheal intubation as a possible pathogenetic pathway. The aim of this study was to investigate the impact of nasotracheal or orotracheal intubation on the development of sinusitis in ICU patients. ⋯ We found that patients intubated orotracheally developed significantly less sinusitis than those intubated nasotracheally. Edema, local infection of the nasal mucosa, or mechanical obstruction of sinus drainage pathways by the tube are possible explanations. The fact that 63% of orally intubated patients had a pathologic maxillary sinus finding as well suggests that in addition to other reasons, an increased central venous pressure, positive pressure ventilation, and the supine position must be regarded as predisposing factors that increase the incidence of sinusitis. We conclude that the conditions of critically ill patients predispose to the development of sinusitis. Nasotracheal intubation is to be regarded as an additional risk, and therefore oral intubation should be preferred.
