JAW THRUST AS A CLINICAL TEST TO ASSESS THE ADEQUATE DEPTH OF ANESTHESIA FOR TRACHEAL INTUBATIONS IN PEDIATRIC INHALATION ANESTHESIA

Abstract

Introduction: Inhalation induction is a common method in pediatrics anesthesia . There is not suitable clincial guide for assessmen depth of anesthesia before intubation, in this study adequacy of Jaw thrust as a guide for this assessement was evaluated.
Methods: In a clinical trial study 90 pediatric patient, ASA1 & 2, six month to 5 year old age, were divided in case and control groups. Inhalation inductions were done by 4% Halothane, 4lit/min O2 and 4Lit/min N2o under spontaneous ventilation. In case and control groups, Jaw thrust and ordinary methods were utilized respectively for assessment of depth of anesthesia befor intubations. Changes in HR, SpO2, end tidal of halothane and duration of induction, duration of laryngoscopy, reactions to intubations and complications were measured and then analyzed by t - test and Chi squar statistical tests.
Results: Duration and complications of larynogscopy were greater in case than control group. Conclusion: Jaw thrust alone is not a good clinical test assessment of depth of anesthesia before intubations in inhalation anesthesia. Probaly one and half to two minutes after negative respones to jaw thrust is a suitable time for intubations in pediatrics inhalation anesthesia .
