Anesthesia experience in 47 patients during posterior fossa surgery: Retrospective study [Posterior Fossa Cerrahisi Uygulanan 47 Hastada Anestezi Deneyimimiz: Retrospektif Çalişma]

Objective: anesthetic approach for posterior fossa surgery brings many problems and concerns for neuro-anesthesiologist. possibility of damage of the vital centers in the brainstem,pneumocephalus,postural hypotension and venous air embolisms may be expected. the aim of this study was to present our experience in 47 patients who underwent posterior fossa surgery and to discuss the current literature on the perioperative management. method: asa risk classification i-iii,47 patients between the ages of 1-77 were evaluated retrospectively who underwent posterior fossa surgery between the years 2013-2016,in our hospital. results: it was determined that the age of the patients ranged from 1 to 77 years and 61.7% of them were men. the most commonly detected histopathological diagnosis was metastasis (44.7%). mean operation time was 194 minutes,mean length of intensive care stay was 4 days,length of hospital stay was 9 days. complications observed during intraoperative period were bradycardia (12.8%),tachycardia (85%),hypotension (8.5%) and hypertension (12.8%). in the follow-up,7 patient (14.9%) required repeated operation,3 patient (6.4%) died,42 (89.4%) patients were discharged from the hospital. conclusion: posterior fossa surgery is a dynamic process that requires intense attention of the anesthesiologist. if the potential situation that may develop in posterior fossa surgery are known and measures can be taken (such as invasive and strich hemdynamic monitdring) for early notication of complications,morbidity and mortality can be reduced with proper treatment.
