OBJETIVOS: Evaluar los efectos electrofisiológicos delsevoflurano en niños con síndrome de Wolff-Parkinson-White (WPW) sometidos a ablación por radiofrecuencia(RF).MÉTODOs: Se estudiaron de forma prospectiva 15pacientes con síndrome de WPW, programados paraestudio electrofiosológico (EEF) y ablación por RF.La inducción anestésica se realizó con fentanilo (2 μkg1), propofol (3 mg kg1) y vecuronio (0,1 mg kg1) y el mantenimiento con propofol (100 μ kg1 min1), bolus de fentanilo y vecuronio según necesidades. El EEF(EEFpropofol) se practicó mediante la introducción de cuatro electrocatéteres intracardiacos. Se determinaron la función del nodo sinusal, la conducción sinoatrial, períodos refractarios (auricular, nodo AV, anterógrado y retrógrado de la vía accesoria, ventricular)y características de la taquicardia ortodrómicainducida. Posteriormente, se intercambió propofol por sevoflurano (1 MAC según edad) repitiendo las mediciones(EEFsevoflurano). Los parámetros EEFpropofol y EEFsevoflurano se compararon mediante el test de Wilcoxon. RESULTADOS: La edad media fue de 9,3 ± 6 años. Trasla administración de sevoflurano se produjo un alargamiento del período refractario efectivo anterógrado de la vía accesoria (EEFpropofol 283 ± 22 ms; EEFsevoflurano 298 ± 25 ms; p = 0,004), y del ciclo mínimo de estimulación con conducción ventrículo-atrial 1:1 (EEFpropofol 244 ± 41 ms; EEFsevoflurano 273 ± 28 ms; p = 0,028). No hubo cambios significativosen el resto de los parámetros. En todos lospacientes se consiguió la ablación de la vía accesoria.CONCLUSIONES: El sevoflurano modificó parcialmentelas propiedades de la vía accesoria, aunque esto no impidióla ablación de la misma
OBJECTIVE: To evaluate the electrophysiologicaleffects of sevoflurane in children with Wolff-Parkinson-White (WPW) syndrome undergoing radiofrequencyablation.METHODS: We performed a prospective study of 15patients with WPW syndrome who were scheduled foran electrophysiological study (EPS) and radiofrequencyablation.Anesthesia was induced with fentanyl (2 μg/kg),propofol (3 mg/kg), and vecuronium (0.1 mg/kg), andinitially maintained using propofol (100 μg/kg), withbolus administration of fentanyl and vecuronium asrequired. Four intracardiac catheters were introducedfor the EPSpropofol, which included measurements ofsinus-node function, sinoatrial-node conduction,refractory periods (atrial, AV-node, accessory pathwayanterograde and retrograde, and ventricular), and thecharacteristics of induced orthodromic tachycardia.The propofol was then replaced with sevoflurane (1MAC adjusted for age) and the measurements wererepeated (EPSsevoflurane). The EPSpropofol and EPSsevoflurane data were compared using the Wilcoxon signed-rank test.RESULTS: The mean (SD) age was 9.3 (6 ) years. Afteradministration of sevoflurane, the duration of the antegrade effective refractory period of the accessory pathway increased (EPSpropofol, 283 (22) ms; EPSsevoflurane, 298 (25) ms; P = .004), as did the duration of the minimum pacing cycle with 1:1 atrioventricular conduction (EPSpropofol, 244 (41) ms; EPSsevoflurane, 273 (28) ms; P = .028). No significant changes were observed in the other parameters. Ablation of the accessory pathway was achieved in all patients.CONCLUSIONS: Sevoflurane partially modified the properties of the accessory pathway but did not prevent ablation
