Observational StudyEvaluation of gastric contents using ultrasound in full-term pregnant women fasted for 8 h: a prospective observational study.
We aimed to evaluate the gastric volume and contents after an 8-h fasting period in full-term, non-laboring, pregnant women following a standardized meal. ⋯ After 8-h fasting following a standardized meal, full-term pregnant non-laboring women are less likely to have a high residual gastric volume.

Observational StudyHigher neutrophil-to-lymphocyte ratio, mean platelet volume, and platelet distribution width are associated with postoperative delirium in patients undergoing esophagectomy: a retrospective observational study.
We investigated whether preoperative inflammatory markers, i.e., the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), mean platelet volume (MPV), and platelet distribution width (PDW) can predict the development of postoperative delirium (POD) after esophagectomy. ⋯ Our analysis results demonstrated that preoperative NLR ≥ 2.45, MPV ≥ 10.4, and PDW ≥ 11.8 were significantly associated with a higher risk of POD after adjustment for possible confounding factors. However, as the AUCs of the preoperative MPV and PDW for the prediction of the development of POD in univariable ROC analyses were low, large prospective studies are needed to confirm this result.

Effects of changes in end-tidal carbon dioxide tension on oral tissue blood flow and tissue oxygen tension during remifentanil infusion in rabbits.
The aim of this study was to investigate the effects of end-tidal carbon dioxide tension (ETCO2) changes during remifentanil infusion on mandibular bone marrow tissue blood flow (BBF), masseter muscle tissue blood flow (MBF), mandibular bone marrow tissue oxygen tension (PbO2) and masseter muscle tissue oxygen tension (PmO2) in rabbits. ⋯ PbO2 and PmO2 remained unchanged despite changes in BBF and MBF during ETCO2 change with or without remifentanil infusion.
