Abstract
Background Traumatic spinal cord injury (SCI) can continue and transform long after the time of initial injury. Preventing secondary injury after SCI is one of the most significant challenges, and early intervention to return the blood flow at the injury site can minimize the likelihood of secondary injury. Objective The purpose of this study is to investigate whether laminectomy can achieve the spinal cord blood flow by measuring the spinal blood oxygen saturation intraoperatively without the presence of light. Methods Between June and August 2021, eight patients were admitted after traumatic spinal cord injury for surgical treatment. We explored the effectiveness of laminectomy and whether the patients required further procedures or not. We used a brain oxygen saturation monitor at the spine injury site under dark conditions. Results Eight cervical trauma patients, six males and two females, underwent laminectomy decompression. Three patients' ASIA grade improved by one level, and one patient showed slight motor-sensory improvement. Oxygen saturation was in the normal range. Conclusion Performing bony decompression can show good results. Therefore, finding an examination method to confirm the improvement of blood perfusion by measuring oxygen saturation at the injury site after laminectomy is essential to avoid other complications.
Highlights
spinal cord injury (SCI) is a life-threatening condition, and deciding the proper treatment method has a significant role in its prognosis
At least 25 well-established secondary injury mechanisms can occur within minutes, weeks, and months following SCI [2]
After an extensive laminectomy (3–4 segments), the spinal cord pulsation (CSF circulation) was observed to check the improvement of blood perfusion. e injury site was checked for the existence of hematoma by direct visualization. e probe was inserted to measure the spinal oxygen saturation about 1 cm away from the dural sac
Summary
SCI is a life-threatening condition, and deciding the proper treatment method has a significant role in its prognosis. Decompression surgery opens the bony canals through which the spinal cord and nerve pass, creating more space for them to move freely. Cord compression against the dura may only occur in a few patients [3]. Performing durotomy with duroplasty can reduce the intraspinal pressure (ISP) and decrease the spinal cord compartment syndrome (SCCS), improving spinal cord perfusion pressure (SCPP) and blood perfusion at the injury site [4, 5]. Confirming blood perfusion after performing laminectomy is essential to avoid durotomy complications and their associated risk. Between June and August 2021, eight patients were admitted after traumatic spinal cord injury for surgical treatment. Erefore, finding an examination method to confirm the improvement of blood perfusion by measuring oxygen saturation at the injury site after laminectomy is essential to avoid other complications Performing bony decompression can show good results. erefore, finding an examination method to confirm the improvement of blood perfusion by measuring oxygen saturation at the injury site after laminectomy is essential to avoid other complications
