Introduction. We present a case of concurrent spontaneous sublingual and intramural small bowel hematoma due to warfarin anticoagulation.Case. A 71-year-old man presented to the emergency department complaining of a swollen, painful tongue. He was on warfarin therapy. Physical examination revealed sublingual hematoma. His international normalized ratio was 11.9. The computed tomography scan of the neck demonstrated sublingual hematoma. He was admitted to emergency department observation unit, monitored closely; anticoagulation was reversed with fresh frozen plasma and vitamin K. 26 hours after his arrival to the emergency department, his abdominal pain and melena started. His abdomen tomography demonstrated intestinal submucosal hemorrhage in the ileum. He was admitted to surgical floor, monitored closely, and discharged on day 4.Conclusion. Since the patient did not have airway compromise holding anticoagulant, reversing anticoagulation, close monitoring and observation were enough for management of both sublingual and spontaneous intramural small bowel hematoma.

SummaryTo elucidate predisposing factors for enlargement of intra-cerebral hematoma (ICH) during warfarin therapy, we reviewed 47 patients on warfarin who developed acute ICH and determined relationships among ICH enlargement, INR reversal and clinical data. Among 36 patients treated to counteract the effects of warfarin within 24 h of onset, ICH increased in 10 patients (enlarged group), but remained unchanged in the remaining 26 (unchanged group), while ICH remained unchanged in another 11 patients in whom the effect of warfarin was reversed after 24 h. The international normalized ratio (INR) was counteracted immediately in 11 patients treated with prothrombin complex concentrate (PCC) but gradually in the other 36 treated by reducing the dose of warfarin, or by administering vitamin K or fresh frozen plasma. Multivariate analysis with a logistic regression model showed an INR value <2.0 at admission or for 24 h after immediate INR correction with PCC prevented ICH enlargement (OR 0.069, 95%CI 0.006-0.789, p = 0.031). An INR value of >2.0 within 24 h of ICH seems an important predisposing factor for ICH enlargement.

Airway obstruction secondary to bleeding from warfarin therapy is difficult to manage and uncommon but has been previously described. Previous reports have emphasized the need for reversal of therapy using vitamin K and fresh frozen plasma (FFP). Where a definitive airway has been required, cricothyroidotomy or tracheostomy seem to have been favoured. Several authors have reported failed attempts at endotracheal intubation due to the obstructive effects of a sublingual haematoma. We report here a case which illustrates how endotracheal intubation can be used successfully under the right conditions. It also highlights the superiority of prothrombin complex concentrate over FFP in achieving rapid reversal of abnormal international normalized ratio in the emergency situation.

AbstractBACKGROUND:The use of prothrombin complex concentrate (PCC) to reverse acquired (coagulopathy of trauma) and induced coagulopathy (preinjury warfarin use) is well defined.OBJECTIVE:To compare outcomes in patients with traumatic brain injury without warfarin therapy receiving PCC as an adjunct to fresh frozen plasma (FFP) therapy compared with patients receiving FFP therapy alone.METHODS:All patients with traumatic brain injury coagulopathy without warfarin therapy who received PCC (25 IU/kg) in conjunction with FFP or FFP alone at our Level I trauma center were reviewed. Coagulopathy was defined as an international normalized ratio &gt;1.5. The groups (PCC + FFP vs FFP alone) were matched using propensity score matching on a 1:2 ratio for age, sex, Glasgow Coma Scale score, Injury Severity Score, head Abbreviated Injury Scale score, and international normalized ratio (INR) on presentation. The primary outcome measure was time to craniotomy. Secondary outcome measures were blood product requirements, cost of therapy, and mortality.RESULTS:A total of 1641 patients were reviewed, 222 of whom were included (PCC + FFP, 74; FFP, 148). The mean ± standard deviation age was 46.4 ± 21.7 years, the median (range) Glasgow Coma Scale score was 8 (3-12), and the mean ± standard deviation INR on presentation was 1.92 ± 0.6. PCC + FFP therapy was associated with an accelerated correction of INR (P = .001) and decrease in overall pack red blood cell (P = .035) and FFP (P = .041) administration requirement. Craniotomy was performed in 26.1% of patients (n = 58). Patients who received PCC + FFP therapy had faster time to craniotomy (P = .028) compared with patients who received FFP therapy alone.CONCLUSION:PCC as an adjunct to FFP decreases the time to craniotomy with faster correction of INR and concomitant decrease in the need for blood product requirement in patients with traumatic brain injury exclusive of prehospital warfarin therapy.

Trauma patients on prescribed warfarin therapy sustaining intracranial hemorrhage can be difficult to manage. Rapid normalization of coagulopathy is imperative to operative intervention and may affect outcomes. To identify and expedite warfarin reversal, we designed a protocol to administer a prothrombin complex concentrate. A Proplex T protocol was instituted in May 2004. It dictated that trauma patients with an International Normalized Ratio (INR) greater than 1.5, history of prescribed warfarin therapy, and intracranial hemorrhage on CT scan receive a prothrombin complex concentrate for reversal of their coagulopathy. Neither the protocol nor the factor concentrate was validated for use in this subset of trauma patients; therefore, adherence to the protocol and use of the factor concentrate was not mandatory. Patients not administered the prothrombin complex concentrate received vitamin K and fresh-frozen plasma. The protocol resulted in an increased number of patients receiving Proplex T (54.3% vs 35.4%, P = 0.047). Protocol patients had improved times to normalization of INR (331.3 vs 737.8 minutes, P = 0.048), number of patients with reversal of coagulopathy (73.2% vs 50.9%, P = 0.026), and time to operative intervention (222.6 vs 351.3 minutes, P = 0.045) compared with control subjects. There were no differences in intensive care unit (ICU) days, hospital days, or mortality. The Proplex T protocol increased the number of patients who received prothrombin complex concentrate, provided rapid normalization of INR, and improved time to operative intervention.

Prophylactic fresh-frozen plasma (FFP) transfusion is often undertaken in hemodynamically stable patients with a minimally elevated international normalized ratio (INR) prior to invasive procedures, despite little evidence in support of this practice. The authors review the current literature in an attempt to clarify best clinical practice with regard to this issue. Although the activated partial thromboplastin time and prothrombin time–INR are useful laboratory tests to measure specific clotting factors in the coagulation cascade, in the absence of active bleeding or a preexisting coagulopathy, their utility as predictors of overall bleeding risk is limited. Several studies have shown an imperfect correlation between mild elevations in the INR and subsequent bleeding tendency. Furthermore, FFP transfusion is not always sufficient to achieve normal INR values in patients who have mild elevations (< 2) to begin with. Finally, there are risks associated with FFP transfusion, including potential transfusion-associated [disease] exposures as well as the time delay imposed by laboratory testing and transfusion administration prior to initiation of procedures. The authors propose that the current concept of a “normal” INR value warrants redefinition to make it a more meaningful clinical tool. Based on their review of the literature, the authors suggest that in a hemodynamically stable patient population there is a range of mildly prolonged INR values for which FFP transfusion is not beneficial, and is potentially harmful.

Management of patients receiving anticoagulants is a major factor in achieving better outcomes. Anticoagulant therapy may need to be discontinued or rapidly reversed before urgent surgery or invasive procedures. In these situations, treatment with concentrated vitamin K, fresh frozen plasma, and/or clotting factors can achieve more rapid anticoagulant reversal than can drug discontinuation alone. Activated prothrombin complex concentrate is used to treat hemophiliac patients with acquired factor VIII inhibitors. Nonactivated prothrombin complex concentrates are used for anticoagulant reversal. The concentrates are effective within minutes of dosing, providing a nearly immediate decrease in the international normalized ratio. The concentrates are lyophilized powders that can be quickly reconstituted, do not require ABO blood typing before use, and contain 25 times the concentration of vitamin K–dependent clotting factors compared with fresh frozen plasma. Studies suggest that the concentrates are associated with better clinical end points than is fresh frozen plasma.

Object A primary goal in the treatment of patients with warfarin-associated subdural hematoma (SDH) is reversal of coagulopathy with fresh-frozen plasma. Achieving the traditional target international normalized ratio (INR) of 1.3 is often difficult and may expose patients to risks of volume overload and of thromboembolic complications. This retrospective study evaluates the risk of mild elevations of INR from 1.31 to 1.69 at 24 hours after admission in patients presenting with warfarin-associated SDH. Methods Sixty-nine patients with warfarin-associated SDH and 197 patients with non–warfarin-associated SDH treated at a single institution between January 2005 and January 2012 were retrospectively identified. Charts were reviewed for patient age, history of trauma, associated injuries, neurological status at presentation, size and chronicity of SDH, associated midline shift, INR at admission and at hospital Day 1 (HD1), concomitant aspirin or Plavix use, platelet count, and medical comorbidities. Patients were stratified according to use of warfarin and by INR at HD1 (INR 0.8–1.3, 1.31–1.69, 1.7–1.99, and ≥ 2). The groups were evaluated for differences the in rate of radiographic expansion of SDH and in the rate of clinically significant SDH expansion resulting in death, unplanned procedure, and/or readmission. Results There was no difference in the rate of radiographic versus clinically significant expansion of SDH between patients not on warfarin and those on warfarin (no warfarin: 22.3% vs 20.3%, p = 0.866; warfarin: 10.7% vs 11.6%, p = 0.825), but the rate of medical complications was significantly higher in the warfarin subgroup (13.3% for patients who did not receive warfarin vs 26.1% for those who did; p = 0.023). For warfarin-associated SDH, there was no difference in the rate of radiographic versus clinically significant expansion between patients reversed to HD1 INRs of 0.8–1.3 and 1.31–1.69 (HD1 INR 0.8–1.3: 22.5% vs 20%, p = 1; HD1 INR 1.31–1.69: 15% vs 10%, p = 0.71). Conclusions Mild INR elevations of 1.31–1.69 in warfarin-associated SDH are not associated with a markedly increased risk of radiographic or clinically significant expansion of SDH. Larger prospective studies are needed to determine if subtherapeutic INR elevations at HD1 are associated with smaller increases in risk of SDH expansion.

Prolongation of prothrombin time (PT) is often encountered in patients with sepsis. On the other hand, thromboelastometry as a global coagulation test might yield normal results. The aim of our study was to evaluate whether prolonged PT in the presence of normal thromboelastometry parameters is associated with severe bleeding in patients with sepsis undergoing invasive procedures. In patients with sepsis undergoing low-risk bleeding invasive procedures (central venous catheter placement, dialysis catheter insertion, drain insertion, and so on) or high-risk bleeding invasive procedures (surgical tracheostomy, surgical laparotomy, thoracotomy, and so on), coagulation was assessed by thromboelastometry using EXTEM test (test for evaluation of the extrinsic pathway of coagulation, contains activator of extrinsic pathway) and with PT. For period of years 2013 to 2016, we assessed occurrence of severe bleeding during those procedures and 24 hours later in patients with prolonged PT and normal thromboelastometry results. This retrospective study was performed at Department of Anaesthesiology and Intensive Care Medicine of Motol University Hospital in Prague. Data from 76 patients with sepsis were analyzed. Median value of international normalized ratio (INR) was 1.59 (min—1.3 and max—2.56), and median value of prothrombin ratio (PR) was 1.5 (min—1.23 and max—2.55) with normal thromboelastometry finding. Despite prolonged INR/PR, no severe bleeding was observed during invasive procedures. Our data show that sepsis may be accompanied by normal thromboelastometry results, despite prolonged values of PT, and invasive procedures were performed without severe bleeding. This approach to coagulation assessment in sepsis may reduce administration of fresh frozen plasma to the patients. The study was registered at Clinical Trials.gov with assigned number NCT02971111.
