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 StudyTEG6s Platelet Mapping assay for the estimation of plasma fibrinogen concentration during cardiovascular surgery: a single-center prospective observational study.
The Activator F (ActF) test on the TEG6s Platelet Mapping assay system is a means of quantifying blood viscoelasticity caused by fibrin network formation, triggered by reptilase and factor XIII, while platelets are inhibited. This unique methodology enables the measurement of blood viscoelasticity, even in highly heparinized blood. Here, we investigated whether fibrinogen concentration could be estimated using the ActF test in blood samples obtained during cardiopulmonary bypass (CPB) and after CPB in patients undergoing cardiovascular surgery. ⋯ TEG6s Platelet Mapping ActF MA values strongly correlated with plasma fibrinogen concentration in highly heparinized blood during CPB and yielded highly accurate measurements of low fibrinogen concentrations.

Review Meta AnalysisAnterior suprascapular nerve block versus interscalene brachial plexus block for arthroscopic shoulder surgery: a systematic review and meta-analysis of randomized controlled trials.
This systematic review aimed to compare the analgesic effectiveness and complications rates for anterior suprascapular nerve blocks (ASSB) compared to interscalene brachial plexus blocks (ISB) for arthroscopic and outpatient shoulder surgery. Only randomized controlled trials (RCTs) comparing the ASSB versus ISB in the context of arthroscopic shoulder surgery were eligible for inclusion. The primary outcomes included pain scores (Numeric Rating Scale of 0 to 10) up to 24 h postoperatively and analgesic consumption. ⋯ There was no difference in respiratory events postblock. ASSB demonstrated a significantly lower incidence of Horner's syndrome (relative risk (RR) = 0.17; 95%CI = 0.08 to 0.39; p < 0.00001; high certainty), voice hoarseness (RR = 0.24; 95%CI = 0.10 to 0.57; p < 0.00001; high certainty) and impaired respiratory function (p < 0.00001). The ASSB could be considered an appropriate analgesic option for arthroscopic shoulder surgery with potentially fewer complications than the ISB.

Quantitative and qualitative analyses of urinary L-FABP for predicting acute kidney injury after emergency laparotomy.
The aim of this study was to explore the clinical utility of urinary L-FABP for earlier prediction of acute kidney injury (AKI) after emergency laparotomy, and to assess the clinical utility of a point-of-care (POC) kit for urinary L-FABP. ⋯ Quantitative L-FABP analyses is suitable for predicting postoperative AKI earlier in the perioperative period of emergency laparotomy. Conversely, the higher specificity of qualitative L-FABP analysis suggests that it may be useful for excluding the risk of AKI but its overall clinical validity should be further investigated.
