Intraoperative thromboelastography-guided transfusion in a patient with factor XI deficiency: A case report.

ABSTRACT:

Background

Factor XI (FXI) deficiency, also known as hemophilia C, is a rare bleeding disorder of unpredictable severity that correlates poorly with FXI coagulation activity. This often poses great challenges in perioperative hemostatic management. Thromboelastography (TEG) is a method for testing blood coagulation using a viscoelastic hemostatic assay of whole blood to assess the overall coagulation status. Here, we present the successful application of intraoperative TEG monitoring in an FXI-deficient patient as an individualized blood transfusion strategy.

Case summary

A 21-year-old male patient with FXI deficiency was scheduled to undergo reconstructive surgery for macrodactyly of the left foot under general anesthesia. To minimize his bleeding risk, he was scheduled to receive fresh frozen plasma (FFP) as an empirical prophylactic FXI replacement at a dose of 15-20 mL/kg body weight (900-1200 mL) before surgery. Subsequent FFP transfusion was to be adjusted according to surgical need. Instead, TEG assessment was used at the beginning and toward the end of his surgery. According to intraoperative TEG results, the normalization of coagulation function was achieved with an infusion of only 800 mL FFP, and blood loss was minimal. The patient showed an uneventful postoperative course and was discharged on postoperative day 8.

Conclusion

TEG can be readily applied in the intraoperative period to individualize transfusion needs in patients with rare inherited coagulopathy.

Project description:IntroductionCytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is a well-established treatment for peritoneal cancer (PC). However, this kind of combination therapy is associated with a high incidence of complications. Moreover, relative studies have indicated that traditional laboratory testing is insufficient to demonstrate the overall haemostatic physiology of CRS/HIPEC. Thromboelastography (TEG), administered by monitoring dynamic changes in haemostasis, has been shown to contribute to reducing transfusion requirements and improving survival. However, there is no evidence to verify whether TEG can be applied to guide transfusion strategies during CRS/HIPEC. Therefore, we aim to investigate whether TEG-guided blood product transfusion (TEG-BT) therapy is superior to traditional blood product transfusion (T-BT) therapy for guiding perioperative blood transfusion treatment and improving the prognosis of patients undergoing CRS/HIPEC.Methods and analysisThe TEG-BT versus T-BT study is a single-centre, randomised, blinded outcome assessment clinical trial of 162 patients with PC, aged 18-64 years and undergoing CRS/HIPEC. Participants will be randomly allocated to receive TEG-BT or T-BT. The primary outcome will be the evaluation of perioperative blood transfusion, which refers to the total amount of blood transfusion given from the time patients enter the operating room up to 72 hours postoperatively. The secondary outcomes will include the transfusion volume during surgery, total amount of intraoperative infusion, amount of blood lost during the operation, total blood transfusion between 0 and 72 hours after surgery, lowest haemoglobin level within 72 hours after surgery, intensive care unit duration, overall length of stay, total cost of hospitalisation and adverse events. Data will be analysed according to the intention-to-treat principle.Ethics and disseminationThe study protocol has been approved by the Scientific Research Ethics Committee of Beijing Shijitan Hospital Affiliated with Capital Medical University (Approval Number: sjtkyll-lx-2020-3). The results will be published in peer-reviewed journals.Trial registration numberChinese Clinical Trial Registry (ChiCTR2000028835).
