Angka kejadian spinal meningioma di Amerika adalah 25 % dari seluruh tumor di regio spinal dan empat kali lebih banyak muncul pada perempuan usia lebih dari 40 tahun dibandingkan pada laki-laki. Delapan puluh persen terjadi di daerah vertebra thorakal, 15% di cervikal, 3% di lumbal dan 2% di foramen magnum. Seorang wanita berusia 42 tahun, GCS 15 dengan diagnosa atlas meningioma, yang dilakukan operasi laminectomu untuk pengangkatan tumor. Pasien mengeluh kesemutan mulai dari tangan kiri diikuti tangan kanan, kaki kiri diikuti kaki kanan sejak 10 bulan yang lalu. Sejak 2 bulan yang lalu pasien mengeluh lemas bila berjalan yang disertai kelemahan kedua tangan, disertai keterbatasan gerak dari leher, tidak ada gangguan berkemih dan defekasi. Intubasi dilakukan dengan cara inline position, operasi berlangsung selama 7 jam dengan total perdarahan 650 cc, rumatan anestesi menggunakan isofluran 0,8–1 vol%, dexmedetomidine 0,2–0,7 mcg/kgbb/jam dan vecuronium 1 mcg/kgbb/mnt. Pascaoperasi pasien tidak diekstubasi, dirawat Neurosurgery Critical Care Unit (NCCU), pernafasan dibantu mesin bantu nafas dengan mode Synchronized Intermittent Mandatory Ventilation (SIMV) dan baru diekstubasi 12 jam pascaoperasi. Tiga hari pascaoperasi pasien dipindahkan ke ruangan dengan GCS 15 dan keadaaan hemodinamik stabil.

Anesthesia Management in Atlas Meningioma Surgery

Abstract

The incidence rate of spinal meningioma in the US is 25% of all tumors in the spinal region and appears four times more in women aged over 40 years old than in men. Eighty percent occurs in the thoracal, 15% in the cervical, 3% in the lumbar and 2% in the foramen magnum. This is a case of a 42-year-old woman with GCS 15 who was diagnosed with high cervical meningioma underwent laminectomy tumor removal. Patient experienced numbness on the left referring to the right hand and left referring to the right hand foot since 10 months ago. Since 2 months ago the patient experienced limp with weakness on both hands and limited neck motion. Patients had no disturbance in micturition and defecation. Intubation was done by inline position while the surgery lasted for 7 hours with 650cc bleeding. Anesthesia was maintained using isoflurane 0.8-1 vol %, dexmedetomidine 0.2-0.7 mcg/kg/h and vecuronium 1 mcg/kg/mnt. After surgery, the patient was not extubated and admitted to NCCU (Neurosurgery Critical Care Unit) with ventilator-mode SIMV (Synchronized Intermittent Mandatory Ventilation). Extubation was performed 12 hours postoperative. Three days after surgery patient was transferred to inpatient ward with GCS 15 and stable hemodynamic status.
