Randomized Controlled TrialUse of high-resolution thermography as a validation measure to confirm epidural anesthesia in mice: a cross-over study.
Effective epidural anesthesia is confirmed in humans by sensory assessments but these tests are not feasible in mice. We hypothesized that, in mice, infrared thermography would demonstrate selective segmental warming of lower extremities following epidural anesthesia. ⋯ Thermography is a useful tool to confirm epidural catheter placement in animals for which subjective, non-noxious, sensory measures are impossible.

Associations of thrombocytopenia, transaminase elevations, and transfusion with laboratory coagulation tests in women with preeclampsia: a cross-sectional study.
Women with preeclampsia may develop coagulopathy, predisposing to bleeding complications. Although guidelines and prior studies conflict, we hypothesized that in preeclampsia, abnormal coagulation test results are more common in women with thrombocytopenia or transaminase elevations and increase the transfusion risk. Our objectives were to investigate: 1. patterns of coagulation testing; 2. relationships between platelet count, transaminase level, and the risk of abnormal coagulation tests; 3. risk of bleeding complications; and 4. characteristics of patients with markedly abnormal coagulation parameters. ⋯ Coagulation testing was inconsistently performed in this cohort. Platelet counts and transaminase levels inadequately detected abnormal coagulation test results. Abnormal coagulation test results were associated with a markedly higher risk for red blood cell transfusion.
