Brief summary
In pediatric patients with no vascular access, anesthesia induction is usually achieved with sevoflurane. The aim of investigators to evaluate the optimum intravenous access time and the corresponding bispectral index (BIS) value in pediatric surgery under sevoflurane anesthesia.
Detailed description
Patients undergoing anesthesia induction must have at least one vascular access opened for administration of intravenous drugs and fluid. In pediatric patients, fear of needles and anxiety about pain can cause discomfort. For this reason, inhalational anesthetics are commonly used for anesthesia induction in children. An ideal inhalational anesthetic agent should have a smooth and fast onset, little irritation to the respiratory tract, and no undesirable side effects. Sevoflurane meets almost all these criteria, so it is commonly used for anesthesia induction in pediatric patients. Studies related to the induction of anesthesia with sevoflurane have mostly focused on the ease of LMA insertion, the recovery characteristics, the hemodynamic variabilities, comparison of high and low initial sevoflurane concentrations, and cost comparisons between fixed 8% versus incremental techniques. However, after loss of consciousness, children subjected to early intravenous cannulation during sevoflurane induction can display movement, breath holding, coughing, and even laryngospasm. Only limited data are available in the literature regarding intravenous access time at anesthesia induction. The aim of the present study was to evaluate the bispectral index (BIS) values and sevoflurane concentrations during induction of anesthesia and to determine the optimum intravenous access time in pediatric patients.
Interventions
A tourniquet was used to raise the vein for entry into the vein every 15 s after the ciliary reflex disappeared. If the patient showed no response to the tourniquet (movement, coughing, or laryngospasm), an experienced anesthesiologist entered a vein in the dorsum of one hand using a 22-24 gauge cannula.
