ABSTRACT

Objetivo: Selección de fármacos anestésicos ideales en cirugía maxilofacial. Material y métodos: Varón de 22 años, 75 kg de peso y 171cm de altura. No premedicado. Parámetros vitales prequirúrgicos: PA120/70; FC72×min; SPO(2)96%; temperatura 36,5°C; ECG 5 derivaciones ritmo sinusal, y capnografía. Preoxigenación por 5min mediante mascarilla facial. Se realiza prueba de olfateo corroborando buena ventilación, se coloca hisopo impregnado de oximetazolina spray 0,05%. Se inicia la administración de dexmedetomidina (concentración de solución 0,8μg/ml) en infusión continua por vía intravenosa a 0,05μg/kg/h con una escala Ramsay 2, se inicia inducción con fentanil 3μg/g, propofol 2mg/kg, rocuronio 0,6mg/kg. Se introduce por narina derecha tubo endotraqueal Murphy N.° 7, lubricado con lidocaína 10% spray, a través de la nasofaringe. Comenzando la cirugía se la ajusta dosis de dexmedetomidina a 0,1μg/kg/h. Durante el acto anestésico-quirúrgico se mantiene con PA entre 84/55 y 90/53mmHg, FC con cifras entre 58-76 por minuto. Resultados: La selección de los fármacos anestésicos permitió lograr la estabilidad hemodinámica y bienestar en el despertar del paciente. Conclusión: La anestesia para cirugía ortognática en la actualidad por su evolución hace necesario combinar diferentes técnicas anestésicas para poder proporcionar a los pacientes tranquilidad, seguridad, bienestar y analgesia postoperatoria.


Objective: Selection of ideal anesthetic drugs in maxillofacial surgery. Material and methods: A 22-year-old male patient weighing 75 kg and 171cm in height, with no premedication. Pre-operative vital parameters were BP 120/70, HR 72× min, SpO2 96%, temperature 36.5 ◦C, sinus rhythm on 5-lead EKG, capnograpy. The patient was subjected to 5 min of pre-oxygenation through a facial mask. The sniff test was performed, good ventilation was confirmed and a Q-tip impregnated in 0.05% oxymetazoline was applied. An intravenous continuous infusion of dexmedetomidine (solution concentration of 0.8 cg/ml) was initiated at a rate of 0.05 mcg/kg/h with a score of 2 on the Ramsay scale. Induction was initiated with fentanyl 3 mcg/kg, propofol 2 mg/kg, rocuronium 0.6 mg/kg. A No. 7 Murphy endotracheal tube lubricated with a 10% lidocaine spray was introduced through the right nostril down to the nasopharynx. At the start of surgery, the dose of dexmedetomidine was increased to 0.1 mcg/kg/h. Intra-operatively, BP was maintained between 84/55mmHg and 90/53mmHg, and HR between 58 and 76 per minute. Results: The selection of anesthetic drugs allowed for hemodynamic stability and comfort on awakening. Conclusion: Anesthesia for orthognathic surgery, as it has evolved today, requires combining different anesthetic techniques in order to ensure that the patient remains calm, comfortable and reassured, with adequate post-operative analgesia.
