Comprehensive evaluation of Chinese herbal compound prescriptions for postoperative spinal cord injury: A network meta-analysis of randomized controlled trials.

ABSTRACT

Background: Spinal cord injury (SCI) is a catastrophic condition associated with spinal nerve damage, which can lead to complete or partial loss of sensory and motor functions. Chinese herbal compound prescriptions (CHCP) have shown varying degrees of therapeutic effects on spinal cord injuries. However, there is a significant lack of clinical evidence-based research to substantiate these effects. Purpose: This study aims to thoroughly assess the viability of CHCPs in postoperative SCI through network meta-analysis. Methods: Computer searches were conducted across multiple databases, including PubMed, Cochrane Library, Embase, Web of Science, CNKI, Wanfang, VIP, and CBM, from their inception until May 2024. The meta-analysis adhered to the PRISMA guidelines and was registered in the PROSPERO database (CRD42023462686). A network meta-analysis was performed using the BUGSnet software package via R. Study design: A network meta-analysis of randomized clinical trials (RCTs). Results: A total of 26 RCTs involving 1848 patients were ultimately included. The network meta-analysis revealed the effectiveness in improving ASIA motor score as follows "HQGZD" > "Other Decoctions" > "BYHWD" > "TDHXD" > "THCQD" > "Surgery". For ASIA sensory score, the effectiveness ranking was "HQGZD" > "Other Decoctions" > "BYHWD" > "TDHXD" > "THCQD" > "Surgery". Additionally, the experimental group had a higher ADL score compared to the control group, with a statistically difference [SMD = 1.08, 95 % CI = (0.88, 1.27), p < 0.05]. The experimental group had fewer adverse events compared to the control group, with a statistically difference [RR = 0.41, 95 % CI (0.22, 0.78), p < 0.05]. Conclusion: The findings suggest that CHCP can mprove postoperative ASIA motor and sensory scores, enhance ADL scores, and reduce adverse events following SCI surgery. Specifically, combining surgery with Huangqi Guizhi Wuwu Decoction or Buyang Huanwu Decoction may provide superior therapeutic effects in SCI treatment. Integrating CHCP into postoperative care for SCI patients may offer potential benefits.
