Study on the Therapeutic Effect of ESPB for Patients Undergoing Percutaneous Vertebroplasty

Abstract

Objective To compare the difference oftherapeutic effect between percutaneous vertebroplasty (PVP)alone and PVP + Erector spinal plane block (ESPB) in the treatment of osteoporotic vertebral compression fracture (OVCF). Methods After admission, 100 patients with osteoporotic vertebral compression fracture were randomly divided into PVP group (control group) and PVP+ESPB group (observation group) by lottery with 50 patients in each group.The visual analog pain scores (VAS) and oswestry disability index (ODI) of each group were compared before surgery, 2 hours after surgery and at the time of hospital discharge. The operation time, filling volume of intraoperative bone cement, intraoperative bloodloss, and surgery cost of each group were compared.Theearly postoperative ambulation time and early postoperative defecation (stool) time ofeach group were compared to explore the difference.Results The PVP+ESPB group had better visual analog pain scores (VAS) and oswestry disability index (ODI) at 2 hours after surgery and at the time of hospital discharge, and better early postoperative ambulation timeand early postoperative defecation (stool) timethan the PVP group (p<0.05). There were no differences in the visual analog pain scoresand oswestry disability index before surgery, operative time, filling volume of intraoperative bone cement, intraoperative blood loss, and surgery cost between the two groups, and no complications occurred between the two groups after surgery and at the time of hospital discharge. Conclusion PVP+ESPB for OVCF is associated with lower VAS, more significant pain relief, and lower oswestry disability index in patients after surgery than PVP alone for OVCF, and patients are able to engage in ambulation time earlier. Meanwhile, PVP+ESPB promotes recovery of intestinalfunction and improves patients’ quality of life so as tocontribute toquick recovery.
