Pengelolaan Anestesi pada Pasien yang dilakukan Eksisi Tumor Medula Spinalis Servikal 2-3 dengan Ventrikel Ekstra Sistole

Abstract

Compression of the spinal cord can cause irritation to the autonomic nervous system. Hyperinervation of sympathetic nerves at high risk for arrhythmias characterized by electrocardiographic results in changes in P-wave duration, QRS duration, ST-segment depression, T-wave peak interval, and ventricular extrasystole. A 52-year-old male with an intra-extramedullar tumor in cervical 2-3, tetraparesis, dysrhythmias, and ventricular extrasystole bigemini. Wide excision of tumor and posterior stabilization would be performed. The pulse was 90x/minute palpable irregularly. Electrocardiography examination revealed irregular rhythm 82 x/minute and ventricular extrasystole 10 x/minute. Echocardiography showed grade 3 diastolic dysfunction with preserved LV function. Before the procedure, the patient was given management for the dysrhythmia and ventricular extrasystole with analgetics and amiodaron 150mg (10ml) in the first 10 minutes followed by 360mg (200mg) for the next 6 hours, 540mg for the next 18 hours and analgetics. General anesthesia carried out with midazolam 3mg, fentanyl 200mcg, lidocaine 60mg, propofol 100mg, and atricurium 30mg, with manual intubation in-line. After arterial line and central venous catheter insertion, the patient was placed in the prone position. Surgery lasted for approximately 6 hours. The patient was treated in the ICU for 2 days before moving to the usual ward. Amiodarone can be considered in ventricular extrasystole requiring immediate treatment with stable hemodynamic.
