Objective

This study was performed to analyze the correlation between perioperative hidden blood loss (HBL) and the general condition of patients undergoing transforaminal lumbar interbody fusion (TLIF).

Methods

We retrospectively analyzed patients who underwent TLIF from July 2017 to July 2019 in our hospital. Sex, age, body mass index, underlying diseases, American Society of Anesthesiologists classification, coagulation function, preoperative and postoperative hemoglobin level and hematocrit, surgery time, fusion level, intraoperative blood loss, and drainage volume were recorded. Postoperative complications were also recorded. The amount of HBL was calculated, and its correlation with related variables was analyzed.

Results

The mean surgery time was 153.32 ± 54.86 minutes. The total perioperative blood loss was 789.22 ± 499.68 mL, including HBL of 315.69 ± 199.87 mL. Pearson correlation analysis showed statistically significant differences in HBL according to the body mass index, hypertension, fibrinogen, surgery time, and fusion level. Multiple linear regression analysis indicated that the surgery time and fusion level were independent risk factors for HBL.

Conclusions

A certain amount of HBL occurs in TLIF surgery and cannot be ignored in daily clinical work. The operation time and surgery level are independent risk factors for HBL.

经椎间孔腰椎椎间融合术患者围手术期隐性失血的危险因素分析。

目的

进行这项研究以分析围手术期隐性失血（HBL）与接受经椎间孔腰椎椎间融合术（TLIF）的患者一般状况之间的相关性。

方法

我们回顾性分析了2017年7月至2019年7月在我院接受TLIF治疗的患者。记录性别，年龄，体重指数，潜在疾病，美国麻醉医师学会分类，凝血功能，术前和术后血红蛋白水平和血细胞比容，手术时间，融合水平，术中失血量和引流量。还记录了术后并发症。计算了HBL的量，并分析了其与相关变量的相关性。

结果

平均手术时间为153.32±54.86分钟。围手术期总失血量为789.22±499.68 mL，其中HBL为315.69±199.87 mL。Pearson相关分析显示，根据体重指数，高血压，纤维蛋白原，手术时间和融合水平，HBL的统计学差异显着。多元线性回归分析表明手术时间和融合水平是HBL的独立危险因素。

结论

TLIF手术中会发生一定量的HBL，在日常临床工作中不可忽视。手术时间和手术水平是HBL的独立危险因素。
