BACKGROUND AND OBJECTIVES: To promote exclusive breastfeeding, supplements are not recommended without medical indications such as clinical evidence of dehydration. Loss of ≥10% of birth weight (BW) often triggers supplementation due to nursery staff's concern for dehydration. Studies have demonstrated that transplacental passage of maternal intrapartum intravenous fluids for anesthesia may inflate BW. Researchers have proposed using newborn's 24-hour weight (24HW), after fluid diuresis, as preferred reference for weight loss calculation...

OBJECTIVE: To test the hypothesis that increasing the intravenous fluid bolus volume at the time of epidural placement in women with narrow pulse pressure would reduce postepidural fetal heart rate (FHR) abnormalities, hypotension, and resuscitative obstetric interventions. METHODS: We performed a single-center randomized controlled trial. Eligible participants were normotensive with a nonanomalous singleton gestation at or after 35 weeks and with a narrow pulse pressure (less than 45 mm Hg) on admission...

Essentials Blood loss and immune reaction are closely related to morbidity and recovery after surgery. We studied the effect of epinephrine plus tranexamic acid on blood loss and immune reaction. Epinephrine plus tranexamic acid reduced postoperative total blood loss and immune reaction. Epinephrine plus tranexamic acid did not increase the incidence of complications. SUMMARY: Background Hemostasis, thrombosis and surgical stress-induced immune reactions are important for perioperative morbidity and recovery after major surgical operations...

Objectives: Penetration of antibiotics into synovial fluid is crucial to combat septic arthritis efficiently. Since linezolid may be used for treatment of septic arthritis when methicillin-resistant bacterial strains are suspected, we investigated its target-site concentrations in synovial fluid. Patients and methods: Ten patients undergoing elective knee arthroscopy were included in this study. Subjects received a single dose of 600 mg of linezolid intravenously and linezolid concentrations were measured in plasma and by using microdialysis in muscle tissue and synovial fluid...

BACKGROUND: Atenolol, a hydrophilic beta blocker, has been used as a model drug for studying passive permeability of biological membranes such as the blood-brain barrier (BBB) and the intestinal epithelium. However, the extent of S-atenolol (the active enantiomer) distribution in brain has never been evaluated, at equilibrium, to confirm that no transporters are involved in its transport at the BBB. METHODS: To assess whether S-atenolol, in fact, depicts the characteristics of a low passive permeable drug at the BBB, a microdialysis study was performed in rats to monitor the unbound concentrations of S-atenolol in brain extracellular fluid (ECF) and plasma during and after intravenous infusion...

Acute lung injury (ALI) is associated with deterioration of alveolar-capillary lining and transmigration and activation of inflammatory cells. Whereas a selective phosphodiesterase-4 (PDE4) inhibitor roflumilast has exerted potent anti-inflammatory properties, this study evaluated if its intravenous delivery can influence inflammation, edema formation, and respiratory parameters in rabbits with a lavage-induced model of ALI. ALI was induced by repetitive saline lung lavage (30 ml/kg). Animals were divided into 3 groups: ALI without therapy (ALI), ALI treated with roflumilast i...

BACKGROUND: The 'Sepsis 6', a care bundle of basic, but vital, measures (e.g. intravenous fluid, antibiotics) has been implemented to improve sepsis treatment. However, uptake has been variable. Tools from behavioral sciences, such as the Theoretical Domains Framework (TDF) may be used to understand and address such implementation issues. This study used a behavioral science approach to identify barriers and facilitators towards Sepsis Six implementation at a case study hospital. METHODS: Semi-structured interviews based on the TDF were conducted with a sample group of consultants, junior doctors and nurses from Emergency Department, Medical and Surgical Admissions, to explore barriers/facilitators to Sepsis Six performance...

BACKGROUND: Fluid and electrolyte therapy is an important component in the care of the hospitalized child. Previous pediatric guidelines have followed the Holliday-Segar method of calculating and delivering maintenance IV fluids, using hypotonic fluids in maintenance therapy. However, research demonstrates that hypotonic fluids can lead to iatrogenic hyponatremia and that isotonic fluid is a safer alternative. OBJECTIVE: To provide the ideal approach to intravenous (IV) fluid use in the hospitalized child and determine the safety and effectiveness of isotonic maintenance fluid therapy...

We reassessed data from a previous study on the transcerebral net exchange of large neutral amino acids (LNAAs) using a novel mathematical model of blood-brain barrier (BBB) transport. The study included twelve healthy volunteers who received a 4-h intravenous lipopolysaccharide (LPS) infusion (total dose: 0·3 ng/kg), a human experimental model of the systemic inflammatory response during the early stages of sepsis. Cerebral blood flow and arterial-to-jugular venous LNAA concentrations were measured prior to and after LPS, and the BBB transport and brain extracellular concentrations of LNAAs were calculated...
