Conditions for endotracheal intubation provided by different dose regimens of atracurium 0.4 mg kg-1 and 0.5 mg kg-1 were studied and compared with each other and with suxamethonium 1.0 mg kg-1. Intubation was attempted at 2.5, 2 min and 1.5 min following a bolus dose of atracurium, and 1 min following suxamethonium. ⋯ Atracurium, when administered 5 min following recovery from a suxamethonium-induced block, had a significantly faster onset of neuromuscular blockade (P less than 0.01) than the onset observed following atracurium alone. Administration of atracurium 0.42 mg kg-1 3 min after an initial dose of 0.08 mg kg-1 of the drug produced a significantly more rapid onset of block when compared with a bolus dose of 0.5 mg kg-1 (P less than 0.02).

Randomized Controlled Trial Clinical Trial
Intranasal administration of nitroglycerine attenuates the pressor response to laryngoscopy and intubation of the trachea.
The intranasal administration of nitroglycerine (NTG) was undertaken in 35 adult female patients 1 min before the induction of anaesthesia. A control group consisting of 32 patients did not receive NTG. Systolic arterial pressure (SAP) and heart rate (HR) were recorded before the induction of anaesthesia and at 0, 3, and 5 min after tracheal intubation. ⋯ SAP did increase significantly in the control group. HR was increased in both groups immediately after intubation (P less than 0.001 and P less than 0.001 respectively). NTG administered intranasally is a safe, simple and effective method to attenuate the hypertensive response to laryngoscopy and tracheal intubation.

Comparative Study[Intubation or tracheotomy in severe subglottic laryngitis].
A retrospective study to assess safety of nasotracheal intubation for subglottic laryngitis in children was conducted in 44 cases treated in the Intensive Care Unit of Hôpital Bretonneau, France between 1971 and 1981. Intubation had been performed in 40 children, and immediate tracheotomy in the other 4. ⋯ The catheter employed in the 3 tracheotomized children with morbilous laryngitis was too large, and laryngeal stenosis developed in 2 of them. These findings demonstrate that when a catheter of correct size (1/2 size below that indicated by the weight and age of the child) is employed, nasotracheal intubation for severe subglottic laryngitis is a safe procedure.
