PURPOSE
This study aimed to evaluate the effect of intraoperative positioning and ocular immobility on the amount of cerebrospinal fluid around the optic nerve in patients undergoing prone spinal surgery by measuring the optic nerve sheath diameter (ONSD) using ultrasound.
METHODS
Consecutive participants ( = 15 patients, 30 eyes) were scanned preoperatively, intraoperatively approximately 20 minutes before the end of the surgery, and postoperatively in the post-anesthesia care unit at least 10 min after the completion of the surgery at one academic hospital.
RESULTS
On average, patients who underwent prone spinal surgery had a 21% increase in ONSD intraoperatively, with a positive time-dependent relationship with the overall length of surgery ( 0.001). ONSDs postoperatively returned to baseline and were not significantly different from preoperative measurements.
CONCLUSION
Our findings suggest pooling and inadequate clearance of perioptic cerebrospinal fluid during prone spinal surgery that improves following termination of the procedure and return of the patient to an upright position.
目的
本研究旨在通过超声测量视神经鞘直径（ONSD），评估俯卧位脊柱手术患者术中体位和眼球固定对视神经周围脑脊液量的影响。
方法
在一家学术医院，对连续入选的参与者（n = 15例患者，30只眼）在术前、术中手术结束前约20分钟以及术后在麻醉后护理单元手术完成至少10分钟后进行扫描。
结果
平均而言，接受俯卧位脊柱手术的患者术中ONSD增加21%，与手术总时长呈正相关（P < 0.001）。术后ONSD恢复至基线水平，与术前测量值无显著差异。
结论
我们的研究结果表明，俯卧位脊柱手术期间视神经周围脑脊液积聚且清除不足，手术结束及患者恢复直立位后情况改善。
