Alfentanil and propofol for difficult tracheal intubation

Alfentanil and propofol for difficult intubation?

Sevoflurane for difficult tracheal intubation.

Three patients in whom difficult tracheal intubation was expected but awake fibreoptic intubation was not feasible presented for head and neck surgery. Anaesthesia was induced rapidly and smoothly by inhalation of sevoflurane followed by fibreoptic or conventional tracheal intubation.

Low-dose rocuronium improves conditions for tracheal intubation after induction of anaesthesia with propofol and alfentanil.

We studied 60 adult patients to assess if low doses of rocuronium improved conditions for tracheal intubation during induction of anaesthesia with propofol 2.5 mg kg-1 and alfentanil 10 micrograms kg-1. In a double-blind, randomized design, patients were allocated to one of three groups: group P = saline; group R1 = rocuronium 0.1 mg kg-1; and group R3 = rocuronium 0.3 mg kg-1. Intubation condi...

Rapid tracheal intubation with propofol, alfentanil and a standard dose of vecuronium.

We studied 60 ASA I patients with Mallampati grade 1 airways to compare emergency intubating conditions with either alfentanil 20 micrograms kg-1, propofol 2.5 mg kg-1 and vecuronium 0.1 mg kg-1, or with thiopentone 5 mg kg-1 and suxamethonium 1 mg kg-1. Ease of laryngoscopy, vocal cord status and cough response were graded. The trachea of all patients was intubated; 83% of patients in the alfe...

Difficult tracheal intubation in obstetrics.

Difficult intubation has been classified into four grades, according to the view obtainable at laryngoscopy. Frequency analysis suggests that, in obstetrics, the main cause of trouble is grade 3, in which the epiglottis can be seen, but not the cords. This group is fairly rare so that a proportion of anaesthetists will not meet the problem in their first few years and may thus be unprepared for...
