Hipotensi Berat Intraoperatif Tiba-Tiba saat Kraniotomi Pengangkatan Meningioma

Abstract

Blood pressure is the multiplication of cardiac output (CO) with systemic vascular resistance (SVR) and CO determined by stroke volume and heart rate frequency. A 61-year-old woman, weight 49 kg, height 154 cm, came to Santosa Hospital Bandung Central in with complaints of a lump on the back of the head that has gotten bigger since 3 years ago and the longer it gets bigger. There were no signs of increased intracranial pressure and other neurological deficits, diagnosed with meningioma with hypertension, tumor removal was carried out in a prone position. Induction with propofol, fentanyl, vecuronium bromide, lidocaine, anesthetic treatment with sevoflurane-oxygen/air and propofol and continuous vecuronium. Intraoperative suddenly occurs 2 times decrease in blood pressure, bradycardia and desaturation. Given liquid with ringerfundin, gelofusin 1 L, blood pack red cells (PRC) 2 units, sulfas atropine, ephedrine and continued with norepinephrine. Post-dissected treated 1 day in the Intensive Care Unit (ICU) and then another 1 day in the High Care Unit (HCU), then moved to the ward and was treated for 3 days before being discharged from the hospital. Severe drops in blood pressure accompanied by severe bradycardia and desaturation are unlikely to be caused by bleeding, but are more likely to be associated with heart disorders. Therapy is carried out by returning these parameters to physiological values as soon as possible. As conclusion, a sudden drop in blood pressure accompanied by bradycardia and desaturation may be due to the occurrence of Bezold-Jarisch Reflexes (BJR).
