Abstract:
Objective:To explore the value of thromboela-stogram (TEG) in predicting the risk of bleeding in patients undergoing thyroid cancer surgery and guiding blood transfusion therapy.Methods:46 patients with hemorrhage after thyroid cancer surgery in General Surgery Department of the Second Hospital of Shanxi Medical University from Sep. 2021 to Sep. 2022 were selected as the hemorrhage group, including 12 males and 34 females. The age ranged from 18 to 76 years old, with an average age of (45.39±8.64). A total of 46 patients with no postoperative bleeding during the same period were selected as control group, including 9 males and 37 females. The average age was (43.86±9.12) years, ranging from 18 to 75 years. Postoperative TEG parameters, thrombin time (fibrinogen), fibrinogen (FIB), prothombin time (PT), thrombin time (thrombin time, TT), activited partial thomboplastin time (APTT) ], Spearman correlation coefficient was used to analyze the correlation between TEG parameters, coagulation parameters and postoperative blood loss. The value of TEG parameters and coagulation indexes in predicting bleeding was evaluated by receiver operating characteristic (ROC) curve.Results:R value (9.81±1.39) min, K value (3.52±0.94) min, PT value (14.12±1.98) s, TT value (21.36±3.21) s and APTT value (40.29±7.18) s in hemorrhage group were higher than those in control group (7.09±1.12) min and 2.75±0.81) min, (12.86±1.74) s, (19.71±2.53) s, (36.15±6.52) s, MA value (51.67±5.13) mm, Angle (47.06±9.24) °, FIB (1.95±0.64) g/L were lower than control group (57.76±6.05) mm, (58.29±10.28) °, (2.41±0.89) g/L (t 1=10.335, t 2=4.209, t 3=3.242, t 4=2.738, t 5=2.895, t 6=5.207, t 7=5.510, t 8=2.846, all P<0.05) ; R-value (11.02±1.26) min and K-value (4.16±0.93) min in patients with high blood (≥10 ml) bleeding group were higher than those in patients with low bleeding (<10 ml) (9.28±1.19) min and (3.24±0.89) min. MA value (48.04±5.01) mm, Angle (42.15±9.14) ° were lower than those of patients with hypohemorrhage (53.26±5.29) mm, (49.21±9.53) ° (t 1=4.484, t 2=3.183, t 3=3.127, t 4=2.340, P<0.05). The amount of blood loss after thyroid cancer surgery was positively correlated with R value and K value, and negatively correlated with MA value and Angle (r 1=0.421, r 2=0.335, r 3=-0.318, r 4=-0.306, all P<0.05). The area under the curve (AUC) of R value, K value, MA value and Angle predicted perioperative bleeding of thyroid cancer surgery was>0.7. R value (7.13±1.15) min, K value (2.81±0.82) min, PT (13.01±1.76) s, TT (20.03±2.60) s, APTT (37.12±6.64) s after treatment were lower than those before treatment (9.81±1.39) min, (3.52±0.94) min, (14.12±1.98) s, (21.36±3.21) s, (40.29±7.18) s, MA value (56.89±5.94) mm, Angle (56.73±9.86) °, FIB (2.35±0.85) g/L were higher than those before treatment (51.67±5.13) mm, (47.06±9.24) °, (1.95±0.64) g/L (t 1=10.076, t 2=3.860, t 3=2.842, t 4=2.184, t 5=2.198, t 6=4.511, t 7=4.854, t 8=2.550, all P<0.05) . Conclusion:TEG parameters R value, K value, MA value and Angle have certain predictive efficacy in predicting bleeding risk of patients undergoing thyroid cancer surgery, and can guide clinical transfusion therapy.
