Fig. 2From: Coagulation during elective neurosurgery with hydroxyethyl starch fluid therapy: an observational study with thromboelastometry, fibrinogen and factor XIIIPerioperative fibrinogen, FXIII, TAT and PAP levels. Black boxes are all patients, whereas the grey boxes are the patients receiving ≥1 L HES. The reference ranges for the variables are indicated by horizontal lines from the Y-axis. In the FXIII graph, values >1.299 were plotted as 1.299. In the TAT graph, one value was omitted from the morning after surgery (449 μg/L). In the PAP graph, one patient was omitted (PAP levels 1997.4–1477.9-1339.3–2296.7 μg/L)Back to article page
