Complications of sevoflurane anesthesia include excitation and bradycardia during induction and agitation after anesthesia. Purpose — to compare the effect of a traditional VIMA technique and a new one, with double-bolus induction by sevoflurane on the incidence of excitation, bradycardia and agitation in children. Material and methods. Dental treatment under conditions of inhalation anesthesia with sevoflurane was performed in 300 children aged 3 to 6 years. The retrospective study included 210 children (traditional VIMA technique) in group 1. The prospective study included 90 children (new VIMA technique) in group 2. The new VIMA technique included a double bolus induction with sevoflurane anesthesia. The first bolus of 6% sevoflurane with O2 (40%) and N2O (60%) was used until the moment of loss of consciousness, and then was discontinued. The child continued to breathe through the anesthesia apparatus for 3—4 minutes, while the concentration of sevoflurane in the exhaled air decreased from 3 to 0.3%. The second bolus of sevoflurane with a fully open evaporator and the previous streams of O2 and N2O started when the decrease in heart rate stopped and its acceleration by 2—3 beats per minute began. The duration of the second bolus was 1.0—1.5 minutes. Laryngeal mask was installed for all children and mechanical ventilation was performed. The maintaining of anesthesia in the groups was the same and included sevoflurane 2.0—2.5% in a flow of the gas anesthetic mixture at a rate of 1.5 L/min (O2 — 0.6 L/min, N2O — 0.9 L/min). The duration of anesthesia in the groups was the same and was 95±10 minutes. Results. Excitation during induction in group 1 was registered in 163 children (77.6%), and only in 19 (21.1%) children in the second group (p<0.001). Bradycardia (HR<75 per minute) in the 1st group was recorded in 76 (36.1%) patients, and in 4 (4.4%) patients in group 2 (p<0.001). Agitation was registered in 52 (24.7%) children in the first group and in 4 (4.4%) in the second group (p<0,006). Conclusion. The new VIMA technique with sevoflurane with double bolus induction of anesthesia provides the effect of preconditioning and minimizes the incidence of bradycardia, excitation and agitation in children.
