50% Effective Concentration of Sevoflurane for Immobility

Anesthetics, Inhalation Clinical Trial

Official title: 50% Effective Concentration of Sevoflurane for Immobility in Cerebral Palsy Children Undergoing Botulinum Toxin Injection

Status Completed

Clinical Trial Summary

Sevoflurane is as attractive inhalation agent fore deep sedation in children undergoing short invasive procedure because of lack of irritation to the respiratory tract, a pleasant odor and rapid clinical effect and recovery due to low blood gas partition coefficient.

The aim of this study is to determine the optimum inspired concentration of sevoflurane required for immobility during botulinum toxin injection in spontaneously breathing children with cerebral palsy.

Clinical Trial Description

All anesthetics were administered by a single experienced anesthesiologist. Anesthetic induction was performed progressively with inhaled 1-8% sevoflurane, if the patient was cooperative, otherwise directly to the 8%, and subsequent maintenance 2% in oxygen at 5 L /min. A face mask was connected to a Mapleson C circuit for it. Patients breathed spontaneously, unaided, via a pediatric face mask. A failure was defined as the patient continued to move after following the study protocol for sevoflurane inhalation. Insufficient sedation was treated with increments of 0.5% concentration to achieve the desired effect, ie, maintenance of immobility during botulinum toxin injection. The sevoflurane concentration in the next patient would be adjusted depending on the success or failure for immobility at given sevoflurane concentration ( if successful, 0.5% lower concentration, if failed, 0.5% higher concentration).

The child was recovered from sevoflurane sedation at the end of botulinum toxin injection and transferred to post-anesthetic care unit. ;
