Abstract:
Objective To explore the anesthetic management during high intensity focused ultrasound(HIFU) for liver cancer. Methods A total of 21 patients underwent combined intravenous and inhaled general anesthesia.The anesthesia was induced by the administration of propofol,midazolam,fentanyl,and vecuronium.Endotracheal intubation was performed for mechanical ventilation.The anesthesia was maintained with inhalation of isoflurane or enflurane combined with additional administration of fentanyl,propofol,and vecuronium.Optimal analgesia and muscular relaxation condition were maintained and the hemodynamic parameters and body temperature were kept stable during the operation.Results All the 21 patients were successfully treated with HIFU under general anesthesia.A deepen anesthesia was required to depress stimulus responses while HIFU treatment in 2 patients.The duration of operation was 245~423 min(329?48 min),the time to recovery from the anesthesia was 7~18 min(11?3 min),and the time to extubation was 9~24 min(15?4 min).A small amount of pleural effusion was observed after operation in 1 patient and spontaneously disappeared after 2 weeks.Conclusions Combined intravenous and inhaled general anesthesia is a safe and effective anesthetic method for HIFU treatment for liver cancer.
