Abstract :
Aim. The aim of this study was to determine whether any hearing loss occurs in the patients who undergo endoscopic urological operations after spinal anesthesia and to investigate whether the size of the needle affects the risk of this complication. Methods. The study was approved by ethical committee and informed consent was obtained from all patients. 30 patients were divided into 2 groups randomly. Spinal anesthesia was performed via L3-4 or L4-5 interspaces with 10 mg 0.5% hyperbaric bupivacaine by using 22 G Quincke needle in Group I patients, and by 26 G Quincke needle in Group II patients. Pure Tone Audiometry and plasma osmolarity calculation of venous blood were done preoperatively and at the 48th hour postoperatively. Systolic blood pressure, diastolic blood pressure, heart rate were recorded with 5 minutes intervals intraoperatively and for 12 hours postoperatively. The patients were evaluated about headache and the other side effects postoperatively. Results. There were no differences between groups about demographic data, hemodynamic parameters and plasma osmolarity (p 0.05). Subclinical hearing loss was observed in 10 patients of Group I (66.6 %) and in 4 patients of Group II (26.6 %). The rate of hearing loss in Group I was statistically higher than in Group II (p 0.05). Headache was seen in 7 patients of Group I and 2 patients of Group II. Conclusion. Finally, it was concluded that dural puncture and cerebrospinal fluid leakage due to big sized spinal needles increase the hearing loss and headache.
