RESUMO
Nasoendotracheal intubation is contraindicated in patients with pan-facial fractures for securing the airway during reconstructive surgery. Oral intubation interferes with intermaxillary fixation during fracture reduction. In these situations, elective tracheostomy is often the airway of choice. However, with the use of rigid internal fixation, postoperative maxillomandibular fixation is unnecessary and traditional tracheostomy may be avoided, unless oral intubation is impossible or long-term airway control is necessary. This article presents Bullard laryngoscopy and submandibular intubation techniques as innovative alternative methods of airway management during surgery. These procedures are indicated in those patients with severe injuries who do not require long-term airway management postoperatively and did not require tracheostomy in the emergency room.

Nitrous oxide analgesia was introduced into obstetrics by a young Polish-Russian physician who manufactured the gas himself, mixed it with oxygen, humidified the mixture with water vapor, and devised a mouthpiece for self-administration. After assessing the results on himself, he evaluated the effects on pain relief, maternal emotion, and maternal and fetal heart rates, as well as on the frequency, duration, and strength of uterine contractions in 25 parturients. He recognized that, in contrast to chloroform, nitrous oxide did not alter uterine activity. He concluded that the advantages of nitrous oxide administration far outweighed its disadvantages.
