The haemodynamic responses to laryngoscopy and intubation after induction of anaesthesia with thiopentone alone or in combination with 1.5 mg.kg-1 lidocaine and/or 1.5 or 3.0 microgram.kg-1 fentanyl were measured in 150 patients over 64 years of age to determine whether lidocaine, fentanyl or both lidocaine and fentanyl attenuated the pressor response. Fentanyl reduced the rises in systolic, diastolic and mean arterial pressures, heart rate, and rate pressure product and lidocaine decreased the rises in arterial blood pressure and rate pressure product (P less than 0.05). Fentanyl decreased the incidence of marked fluctuations in haemodynamic variables, often seen in geriatric patients (P less than 0.05). ⋯ Fentanyl-treated patients had a higher incidence of hypotension (P less than 0.05). Respiratory depression developed in only one per cent of the fentanyl-treated patients. Both lidocaine and fentanyl are recommended adjuncts to induction of anaesthesia with thiopentone in geriatric patients.

Case ReportsEndotracheal tube rupture, accidental extubation, and tracheal avulsion: three airway catastrophes associated with significant decrease in leak pressure.
We report three unusual, catastrophic cases in which a significant decrease in leak pressure around a tracheal tube was noted before the discovery of the ultimate airway problem. A brief review of potential causes of a decrease in leak pressure is included and management of these difficult cases is discussed.

Transillumination of the cervical airway with the light wand for blind intubation is a valuable adjunct to anesthesiologists and emergency room physicians, particularly for management of the complicated airway in which direct visualization of the larynx is not possible. However, as an alternative to traditional methods, this technique should be practiced in simple cases before it is attempted in more difficult airway cases. ⋯ The incidence of complications remains low but complications may be serious when they occur. We present a case of cricoarytenoid subluxation after blind intubation with a lighted stylet.

There are little data available on success rates, complications, and efficacy of intubation in the pediatric age group by prehospital personnel. In a 12-month period, paramedics successfully intubated 32 of 36 (88.9%) patients for various indications, with a total of 67 attempts. Seventeen of 36 (47.2%) patients survived to hospital admission. ⋯ Paramedics used the straight blade in 21 of 37 patients (56.8%). The study demonstrates that paramedics can intubate pediatric patients with the same success rate as in adult patients. The data support the inclusion of pediatric endotracheal intubation in the scope of paramedic practice.
