Abstract

Purpose

This study was designed to investigate the cardiovascular effects related to tracheal extubation or laryngeal mask airway (LMA) removal in children.

Methods

Sixty children, ASA physical status I, 4–10 yr of age, undergoing minor elective surgery (inguinal hernia and phimosis) were allocated randomly to have their surgery performed with endotracheal intubation (Group ET, n = 30) or LMA (Group LMA, n = 30) and were studied for cardiovascular responses related to extubation or LMA removal. Changes in heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured before and 1,2,3,5, and 10 min after tracheal extubation or LMA removal when the patients were awake.

Results

The maximal changes in HR, SBP and DBP were less in Group LMA than in Group ET during the observation period (HR; 12 vs 26, SBP; 14vs 28, DBP; 9 vs 13, median,P < 0.05).

Conclusion

Laryngeal mask airway removal elicited less haemodynamic change than tracheal extubation in paediatric patients.

Résumé

Objectif

Le but de cette étude était d’évaluer les effets cardiovasculaires de l’extubation tracheale ou du retrait du masque laryngé (ML) chez l’enfant.

Méthodes

Soixante enfants, ASA I, âgés de 4 à 10 ans, soumis à une chirurgie mineure élective (herniotomie inguinale et circoncision), ont été distribués aléatoirement en 2 groupes selon que la chirurgie était effectuée avec intubation endotracheale (groupe ET n = 30), ou avec masque laryngé (groupe ML, n = 30), et ont été étudiés à propos de leur réponse cardiovasculaire en relation avec l’extubation ou le retrait du masque laryngé. Les changements de la fréquence cardiaque (FC), de la pression systolique (TAS) et de la pression diastolique (TAD) ont été mesurés avant et à 1,2,3,5, 10 après l’extubation, ou après le retrait du ML, alors que les patients étaient éveillés.

Résultats

Les variations maximales de RC, TAS, TAD étaient moindres dans le groupe ML que dans le groupe ET durant la période d’observation : les valeurs médianes étaient RC 12 vs 26, TAS 14 vs 28, TAD 9 vs 13; (P < 0,05).

Conclusion

Le retrait du masque laryngé entraîne moins de changements hémodynamiques que l’extubation chez les patients pédiatriques.
