Abstract Background Post-hepatectomy liver failure (PHLF) is a serious complication of hepatectomy. The current criteria for PHLF diagnosis (ISGLS consensus) require laboratory data on or after postoperative day (POD) 5, which may delay treatment for patients at risk. The present study aimed to determine the associations between early postoperative (POD1) serum aminotransferase levels and PHLF. Methods The medical records of patients who underwent hepatectomy at Ramathibodi Hospital from January 2008 to December 2019 were retrospectively examined. Patients were classified into PHLF and non-PHLF groups. Preoperative characteristics, intraoperative findings, and early postoperative laboratory data (serum AST, ALT, bilirubin, and international normalized ratio (INR) on POD0 to POD5) were analyzed. Results A total of 890 patients were included, of whom 31 (3.4%) had PHLF. Cut-off points for AST of 260 U/L and ALT of 270 U/L on POD1 were predictive of PHLF. In multivariate analysis, AST >260 U/L on POD1, ICG-R15, major hepatectomy, blood loss, and INR were independently associated with PHLF. Conclusions Early warning from elevated serum AST on POD1, before a definitive diagnosis of PHLF is made on POD5, can help alert physicians that a patient is at risk, meaning that active management and vigilant monitoring can be initiated as soon as possible.

Maprotiline is a tetracyclic antidepressant which appears to have accounted for a relatively large proportion of the seizures associated with antidepressant use. The literature proposes two mechanisms of seizure induction: interaction with other medications and concomitant medical conditions lowering the seizure threshold. Observations during a study of maprotiline blood levels suggest that elevated serum concentrations achieved with therapeutic doses may also be linked to the seizure-induction mechanism. Monitoring of maprotiline blood levels may help to identify patients at risk.

Objective To report a case of hypoprothrombinemia associated with the use of cefmetazole sodium, define patients at risk for this adverse effect, and identify options to prevent this problem. Case Summary A malnourished patient with endstage renal disease received cefmetazole following a below-the-knee amputation of the right leg. Three days later, a prothrombin time (FT) and an international normalized ratio (INR) were obtained and were markedly elevated from baseline; however, the patient had no clinical symptoms of bleeding. Cefmetazole was discontinued. Vitamin K and fresh frozen plasma were administered. The PT and INR normalized within 24 hours and remained normal throughout the remainder of hospitalization. Discussion The incidence of hypoprothrombinemia associated with cefmetazole reported in the literature is conflicting and not consistent. There are three proposed mechanisms of cephalosporin-associated hypoprothrombinemia, two of which involve the N-methylthiotetrazole (NMTT) chain. The most plausible mechanism is NMTT inhibition of vitamin K epoxide reductase in the liver. Patients at an increased risk for this adverse event include those with low vitamin K stores, specifically patients who are malnourished, with low albumin concentrations and poor food intake. The elderly and patients with liver or renal dysfunction are examples of populations at risk. Conclusions Hypoprothrombinemia may occur with cephalosporins and is especially problematic with those containing an NMTT side chain. Clinicians need to identify patients at risk for developing antibiotic-associated hypoprothrombinemia, monitor them closely, and give vitamin K as prophylaxis accordingly.

Objective: To report 6 patients taking oral vitamin K1 (phytonadione) to reduce warfarin's activity. Case Summary: Six patient cases are summarized in which oral vitamin K1 was used to reduce the international normalized ratio (INR) in patients at risk of bleeding. Discussion: The use of oral vitamin K1 to antagonize warfarin's effects is discussed, as well as the benefits of oral vitamin K1 administration and the disadvantages of parenteral vitamin K1 administration. In addition, an extensive literature review of the discovery and clinical development of warfarin and vitamin K1 is described. Conclusions: In patients receiving warfarin therapy who have an increased INR and are at risk of bleeding, oral vitamin K1 therapy may be safer, less painful, and more cost-effective than the traditional parenteral route of administration.

Most retrospective studies evaluating fresh-frozen plasma:packed red blood cell ratios in trauma patients requiring massive transfusion (MT) are limited by survival bias. As prospective resource-intensive studies are being designed to better evaluate resuscitation strategies, it is imperative that patients with a high likelihood of MT are identified early. The objective of this study was to develop a predictive model for MT in civilian trauma patients. Patients admitted to the University of Alabama at Birmingham Trauma Center from January 2005 to December 2007 were selected. Admission clinical measurements, including blood lactate 5 mMol/L or greater, heart rate greater than 105 beats/min, international normalized ratio greater than 1.5, hemoglobin 11g/dL or less, and systolic blood pressure less than 110 mmHg, were used to create a predictive model. Sensitivity (Sens), specificity (Spec), positive predictive value (PPV), and negative predictive value (NPV) were calculated for all possible combinations of clinical measurements as well as each measure individually. A total of 6638 patients were identified, of whom 158 (2.4%) received MT. The best-fit predictive model included three or more positive clinical measures (Sens: 53%, Spec: 98%, PPV: 33%, NPV: 99%). There was increased PPV when all clinical measurements were positive (Sens: 9%, Spec: 100%, PPV: 86%, NPV: 98%). All combinations or clinical measures alone yielded lower predictive probability. Using these emergency department clinical measures, a predictive model to successfully identify civilian trauma patients at risk for MT was not able to be constructed. Given prospective identification of patients at risk for MT remains an imprecise undertaking, appropriate resources to support these efforts will need to be allocated for the completion of these studies.
