Abstract
Cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) is beneficial in peritoneal carcinomatosis. Epidurals provide excellent pain relief for laparotomies. Coagulopathy (platelet count <100 × 109/L, INR>1.5 or PTT >45) occurs with CRS and HIPEC, increasing risk for bleeding complications with epidurals. This prospective study characterizes clot kinetics with thromboelastography (TEG) to determine suitability for epidural analgesia. After Research Ethics approval, thirty consented patients had blood collected. Primary data collected included TEG and conventional coagulation measures (platelets, PTT and INR). Secondary data collected included demographics, disease, surgical, intraoperative factors and complications from epidural placement. Of 30 patients analyzed, two had incomplete data. Four developed abnormal coagulation between the second and fifth post-operative day. For all patients, TEG values remained normal. Postoperative INR was elevated until day 3 (all INR < 1.5). 17 patients received epidural analgesia, 3 demonstrated abnormal conventional coagulopathic criteria despite normal TEG. In this study CRS and HIPEC do not contribute to the conventional definition of clinical coagulopathy. Clot kinetic...Continue Reading
