目的 分析血红蛋白水平对上肢骨折患者深静脉血栓形成(DVT)的影响。方法 采用回顾性分析法,对2018年1月—2021年6月期间来我院进行治疗的386例上肢骨折患者展开研究,依据患者是否发生DVT分为DVT组(n=114)和对照组(n=272)。对2组患者的各项一般资料和临床资料进行比较,对有统计学意义的因素进一步行Logistic多因素回归分析,探究上肢骨折患者发生DVT的危险因素,并Pearson分析血红蛋白水平与各危险因素的相关性。结果 与对照组相比,DVT组患者为女性、年龄＞60岁、体质量指数(BMI)＞25 kg/m²、冠状动脉粥样硬化性心脏病、糖尿病、合并其他骨折、受伤至超声检查时间≥3 d、受伤至手术时间＞5 d、纤维蛋白降解产物(FDP)≥35 mg/L、凝血酶时间(TT)≥17 s、血红蛋白≤120 g/L、血小板计数/血红蛋白比值≥2.5、血糖≥8 mmol/L、全身麻醉、术后住院时间＜7 d的发生率升高,差异有统计学意义(P＜0.05)。Logistic多因素回归分析显示,年龄＞60岁、BMI＞25 kg/m²、受伤至手术时间＞5 d、血红蛋白≤120 g/L、血小板计数/血红蛋白比值≥2.5、血糖≥8 mmol/L是上肢骨折患者发生DVT的危险因素(P＜0.05)。上肢骨折患者的血红蛋白水平与年龄、BMI、受伤至手术时间、血小板计数/血红蛋白比值、血糖水平呈现负相关(P＜0.05)。结论 血红蛋白≤120 g/L是上肢骨折患者发生DVT的危险因素,与DVT的发生存在相关性。

Objective To analyze the influence of hemoglobin level on deep vein thrombosis (DVT) in patients with upper extremity fractures. Methods A retrospective study of 386 upper extremity fracture patients who came to our hospital for treatment from January 2018 to June 2021 was carried out.According to whether the patients had DVT or not, they were divided into DVT group (n=114) and control group (n=272).The general data and clinical data of the two groups were compared, and the statistically significant factors were further analyzed by Logistic multivariate regression analysis to explore the risk factors of DVT in patients with upper limb fractures, and analyzed the hemoglobin level and the risk factors correlation by Pearson. Results Compared with the control group, the DVT group had increased incidence in female, age >60 years old, body mass index (BMI) >25 kg/m², coronary heart disease, diabetes mellitus, other fractures, injury to ultrasonic time ≥3 days, injury to operation time >5 days, fibrin degradation products (FDP) ≥35 mg/L, thrombin time (TT) ≥ 17 s, hemoglobin ≤120 g / L, platelet count / hemoglobin ratio ≥2.5, blood glucose ≥8 mmol/L, general anesthesia and postoperative hospital stay <7 days, and the difference was significant (P<0.05).Logistic multivariate regression analysis showed that age>60, BMI>25 kg/m², time from injury to operation>5 days, hemoglobin≤120 g/L, platelet count/hemoglobin ratio ≥2.5, blood glucose ≥8 mmol/L were the risk factors of DVT in patients with upper extremity fractures (P<0.05).The hemoglobin level of those patients was negatively correlated with age, BMI, time from injury to operation, platelet count/hemoglobin ratio and blood glucose level (P<0.05). Conclusions Hemoglobin ≤120 g/L was a risk factor for DVT in patients with upper extremity fractures, and it was related to the occurrence of DVT.

目的 研究碳氧血红蛋白在新生儿ABO溶血病中的诊断价值。方法 将患者分为三组,选取144例足月新生儿ABO溶血病患儿为溶血组(A组),选取同期160例不合并溶血的足月黄疸新生儿为非溶血性黄疸组(B组),同时与88例足月健康新生儿(C组)对比。分析三组间碳氧血红蛋白、总胆红素、红细胞计数等有无差异。结果 溶血组患儿的碳氧血红蛋白水平较健康新生儿高,两组间差异有统计学意义(P＜0.001)。同时,溶血组患儿的碳氧血红蛋白水平较非溶血性黄疸组患儿高,两组间差异有统计学意义(P＜0.001)。碳氧血红蛋白在非溶血性黄疸组和健康新生儿组无统计学差异。碳氧血红蛋白ROC曲线值为1.27%时诊断新生儿ABO溶血病的敏感度和特异度最高(分别为90%和70%,P＜0.001)。溶血组患儿总胆红素水平与碳氧血红蛋白呈正相关关系(r=0.83523,P＜0.001),非溶血性黄疸患儿总胆红素水平与碳氧血红蛋白无相关性(r=0.12571,P＞0.05),溶血组患儿组总胆红素水平低于非溶血性黄疸患儿,而碳氧血红蛋白水平高于非溶血性黄疸患儿(P＜0.001)。结论 碳氧血红蛋白对新生儿ABO溶血病的诊断有临床意义,同时碳氧血红蛋白检测可作为体内胆红素产生量的指标,其有助于黄疸病因的鉴别、诊断及治疗。

Objective To explore clinical significance of determination of carboxyhemoglobin in ABO hemolytic disease of the newborn. Methods A total of 392 cases were randomly selected in the study. The experiment consisted of three groups: a total of 144 newborns consecutively hospitalized with ABO hemolysis were treated as experimental group(Group A); 160 newborns with hyperbilirubinemia and without hemolysis were collected(Group B); and 88 healthy newborns at term were the control group(Group C). Carboxyhemoglobin, serum total bilirubin and hemoglobin was collected and were compared with in the three subgroups. Results Compared with group C, carboxyhemoglobin were higher in ABO hemolytic disease(P<0.001). Compared with group B, carboxyhemoglobin were higher in ABO hemolytic disease(P<0.001), while carboxyhemoglobin showed no significant difference between group B and C (P>0.05). A carboxyhemoglobin cut-off value of 1.27% had 90% sensitivity and 70% specificity for predicting prescription. There was a positive correlation between total bilirubin level and carboxyhemoglobin level in newborns with ABO hemolysis(r=0.83523,P＜0.001). Conclusion Carboxyhemoglobin indicates the procedure of ABO hemolytic disease of the newborn, which is helpful to diagnose the cause of hyperbilirubinemia and taken as a guide in therapy.
