Work practices relating to intubation and associated procedures in intensive care units in Sweden.
A survey into the current usage of tracheal tubes and associated procedures, such as various sedation regimes and antacid therapy, in intensive care units was carried out in Sweden by sending a questionnaire to physicians in charge of intensive care units in 70 acute hospitals which included seven main teaching hospitals. The purpose of the survey was to see how far the recent advances in tube and cuff design and awareness of the problems caused by prolonged therapeutic paralysis in intensive care units have influenced the attitudes and work practices of physicians in Sweden. Forty-nine replies were received (a 70% response rate). ⋯ The majority of units rarely used muscle relaxants. Phenoperidine and diazepam were the most popular drugs used for the sedation technique. 71.4% of teaching hospitals and 40.9% of non-teaching hospitals used antacids routinely in patients on intermittent positive pressure respiration. The results are discussed.

Endotracheal intubation has proven to be a relatively safe and effective means of securing the airway in neonates. Some concern remains, however, regarding airway management in critically ill infants who require assisted ventilation for extended periods. Among the various risk factors associated with the complication of acquired subglottic stenosis in neonates, the one most frequently cited has been "prolonged" intubation, although opinion varies regarding the definition of this term. ⋯ The incidence of subglottic stenosis for infants whose duration of intubation ranged from 3 to 50 days was 0.4% (1/245). Infants with birth weights less than 1,500 g appeared more susceptible to the development of intubation-related laryngeal injury. The conclusion of this study is that endotracheal intubation is an appropriate means of long-term airway management in neonates hospitalized in a pediatric intensive care unit, providing other known risk factors are minimized.

Nasotracheal intubation has been demonstrated to be effective in supporting the airways of children with acute epiglottitis. Length of intubation and criteria used for extubation are still controversial. A 6-year retrospective review at Children's Hospital of Pittsburgh identified 100 cases of acute epiglottitis, which were initially managed with nasotracheal intubation. ⋯ The percent of children intubated longer than 48 hours decreased from 69% to 22% in the same time period. These data indicate that a shorter period of intubation is aided by daily laryngeal inspection in the ICU. We propose a staging system for acute epiglottitis to aid in the decision to safely extubate these children.

Comparative Study
Neuromuscular blockade for rapid tracheal intubation in children: comparison of succinylcholine and pancuronium.
To compare the effectiveness of succinylcholine and pancuronium for rapid intubation in children, 49 healthy children ages two to eight years were studied. After induction of anaesthesia with thiopentone and atropine, and administration of droperidol, fentanyl, nitrous oxide, and oxygen, each child received one of the following muscle relaxants: succinylcholine 1.5 mg X kg-1 (n = 12), succinylcholine 1.0 mg X kg-1 (n = 13), pancuronium 0.15 mg X kg-1 (n = 11), or pancuronium 0.10 mg X kg-1 (n = 13). The force of thumb adduction was measured by stimulating the ulnar nerve with repetitive supramaximal single twitches (0.15 Hz). ⋯ The intubating conditions were excellent in 100% of the children who received succinylcholine 1.5 and 1.0 mg X kg-1, and pancuronium 0.15 mg X kg-1, but were excellent in only 69 per cent of those who received pancuronium 0.10 mg X kg-1. We conclude that succinylcholine 1.5 mg X kg-1 produces the most rapid onset of excellent intubating conditions in children. In children in whom succinylcholine is contra-indicated, pancuronium 0.15 mg X kg-1 provides excellent intubating conditions within 80 seconds.
