摘要:

背景:脊柱内固定后感染是其严重并发症,多项研究表明血沉及C-反应蛋白在判断感染方面具有重要意义。
目的:文章分析颈椎内固定后无感染患者血沉及C-反应蛋白的变化趋势。
方法:回顾性分析2013年10月至2014年7月收治的颈椎内固定患者56例,根据内固定方式分为2组,颈椎前路组为行颈椎前路减压植骨融合内固定的患者29例,颈椎后路组为行颈椎后路单开门减压内固定患者27例。内固定前、内固定后第1,3,6,9天清晨采集患者外周血,检测血沉及C-反应蛋白值,随访超过1年,未出现感染迹象。
结果与结论:①一般规律:颈椎内固定后,患者血沉在第6天显著升高并达到峰值,随后逐渐下降,第9天仍未降至正常;C-反应蛋白在第3天显著升高并达到峰值,随后迅速下降,第9天仍未降至正常;颈椎后路组患者内固定后第3,6,9天血沉水平明显高于颈椎前路组(P < 0.05),C-反应蛋白差异无显著性意义(P > 0.05)。②结果说明,C-反应蛋白是颈椎内固定后监测患者炎症反应的重要指标,有助于内固定后早期感染的判断。内固定后早期血沉及C-反应蛋白2种炎症指标的异常,并不提示内固定后刀口感染的存在。C-反应蛋白可在内固定后第3天达到峰值,建议在第2,3天查血,随后如无明显反弹,则感染可能性小;内固定后炎症指标下降后再次升高或下降缓慢,可能提示感染的存在。

Abstract:

BACKGROUND: The infection after spinal internal fixation was its serious complications. A number of studies have shown that erythrocyte sedimentation rate and C-reactive protein are of great importance in judging infections.
OBJECTIVE: To analyze the trend of change of erythrocyte sedimentation rate and C-reactive protein for patients without infection after the cervical fixation.
METHODS: Totally 56 patients, who underwent cervical fixation from October 2013 to July 2014, were retrospectively analyzed, and then divided into anterior cervical group (n=29) and posterior cervical group (n=27). Patients in the anterior cervical group underwent anterior cervical decompression bone graft internal fixation. Patients in the posterior cervical group underwent posterior cervical unilateral open door decompression internal fixation. The peripheral blood was collected before fixation and at the early morning of the 1, 3, 6, 9 days after fixation. Erythrocyte sedimentation rate and C-reactive protein values were determined. The follow-up of patients was more than one year. Signs of infection did not appear.
RESULTS AND CONCLUSION: (1) General rule: After the cervical fixation, the erythrocyte sedimentation rate


was increased significantly and reached a peak on postoperative day 6. The peak level gradually decreased but has not returned to normal at the 9 postoperative days. The C-reactive protein increased significantly on the first postoperative day and reached a peak on postoperative day 3. The peak level rapidly decreased but has not returned to normal at the 9 postoperative days. The level of erythrocyte sedimentation rate of patients in the posterior cervical group was significantly higher than that in the anterior cervical group at 3, 6 and 9 days after internal fixation (P < 0.05). There was no significant difference in the C-reactive protein between these two groups (P > 0.05). (2) These results demonstrate that C-reactive protein is an important indicator of monitoring the inflammatory response of patients after cervical internal fixation, which was conductive to the judgment of early infection after internal fixation. The abnormal inflammatory indices of erythrocyte sedimentation rate and C-reactive protein do not suggest a presence of blade infection after internal fixation. C-reactive protein can reach the peak at 3 days after fixation. It is recommended to check blood at 2 and 3 days. If there is no apparent rebound, then the possibility of infection is small. It may indicate the presence of infection if the inflammatory indices increased again or decreased slowly after the decrease.
