Although tracheostomy is performed most commonly for ventilator-dependent patients who have had prolonged periods of endotracheal intubation, it is still necessary and used for other airway problems. Patient management as it relates to indications, timing, various surgical techniques, types of tubes, and complications of tracheostomy and other forms of airway maintenance and control are discussed and evaluated.

Review Case Reports
Retrograde intubation of the pharynx: an unusual complication of emergency cricothyrotomy.
Retrograde, translaryngeal intubation of the pharynx, a previously unreported and potentially fatal complication of emergency cricothyrotomy, is described. Methods of avoiding this complication are discussed. Reports in the literature of related technical errors following successful surgical incision of the cricothyroid membrane are discussed.

Review[Consequences and prevention methods of hemodynamic changes during laryngoscopy and intratracheal intubation].
In patients ranked ASA 1, laryngoscopy and intubation lead to an average increase in blood pressure of 40 to 50%, and a 20% increase in heart rate. These changes, which are greatest one minute after intubation, last for 5 to 10 min. They are due to sympathetic and adrenal stimulation, which may also result in some arrhythmias. ⋯ In clinical practice, prevention will first rely on a sufficient dose of narcotics. In some cases, nitroglycerin or beta blockers may be used so as to decrease the doses of narcotics, without altering their efficacy; however, the risk of hypotension should be constantly borne in mind. If preventing measures have not been taken, short-acting antihypertensive agents (beta blockers, calcium blockers) should be used in patients who develop major hypertension during laryngoscopy and intubation.

Review Case Reports[Tracheal intubation in patients with cervical spine injuries using a fiber optic laryngoscope].
Eleven patients, with a cervical spine injury and scheduled for elective cervical spine fusion at least 48 h after their initial trauma, were intubated using a new fiberoptic laryngoscope (Bullard). This technique uses either a semi-rigid guide independent of the laryngoscope blade, or a rigid one attached to the blade. The cervical spine was immobilized with either a collar or a halo. ⋯ This is confirmed by the time required, 44 +/- 22 sec for the rigid guide, and 97 +/- 92 sec for the semi-rigid one. In the patient in whom this technique failed at the first attempt, endotracheal intubation was carried out by the nasal route and controlled by the fiberoptic laryngoscope. This technique enables a rapid and easy orotracheal intubation in trauma patients with an immobilized cervical spine, but careful training is necessary.
