Objective: To compare the acute hemodynamic effects of intravenous fasudil with different dosage on patients with congenital heart defects (CHD) and severe pulmonary arterial hypertension (PAH). Methods: Sixty patients (37±17 years old) with CHD and PAH were consecutively enrolled. All patients underwent heart catheterization. The patients were randomly divided into two groups: the regular dosage group and the large dosage group. At initiation and 30 min after intravenous fasudil(30 mg and 60 mg respectively), the following hemodynamic parameters were measured and calculated: right atrial pressure(RAP), pulmonary arterypressure(PAP) , systemic artery pressure (SAP), pulmonary capillary wedge pressure(PCWP) , pulmonary vascular resistance(PVR) and systemic vascular resistance( SVR), cardiac index (CI) and artery oxygen saturation (SaO(2))...

Background: Hospitalized children are at risk of medication errors (MEs) due to complex dosage calculations and preparations. Incident reporting systems may facilitate prevention of MEs but underreporting potentially undermines this system. We aimed to examine whether scenarios involving medications should be reported to a national mandatory incident reporting system and the likelihood of self- and peer-reporting these scenarios among paediatric nurses and physicians. Methods: Participants' reporting of MEs was explored through a questionnaire involving 20 medication scenarios...

In health care, efforts have been aimed at reducing medication errors rates; yet, medication errors continue to affect approximately 5% of hospitalized patients. In health care education, simulation provides nursing students a safe opportunity for hands-on medication administration, often including dosage calculation. However, the safety checks associated with medication administration-including the Five Rights-are frequently overlooked. Although the efforts aimed toward increasing medication safety include external factors (such as environmental measures and electronic resources), recent observations in simulation suggest a different problem...

Body surface area(BSA)is a parameter frequently used to calculate the chemotherapy dosage. Several different equations for predicting BSA have been developed. We examined the formula suggested for BSA calculation for 62 chemotherapy drugs where the recommended dosage was based on patient BSA. We found that the description of the formula to be used for BSA calculation was not provided in the package inserts or in the drug interview forms in the majority of cases; the BSA formula was mentioned in the guide for appropriate use of medication in only 8 of 62 chemotherapy drugs...

Background: The high cost of intrathecal morphine pump (ITMP) implantation may be the main obstacle to its use. Since July 2014, the Korean national health insurance (NHI) program began paying 50% of the ITMP implantation cost in select refractory chronic pain patients. The aims of this study were to investigate the financial break-even point and patients' satisfaction in patients with ITMP treatment after the initiation of the NHI reimbursement. Methods: We collected data retrospectively or via direct phone calls to patients who underwent ITMP implantation at a single university-based tertiary hospital between July 2014 and May 2016...

AIM: To develop a population pharmacokinetic model and identify sources of variability, genetic and nongenetic factors, of tenofovir. METHODS: The ABCC2 and ABCC4 polymorphisms were genotyped in 342 patients. A nonlinear mixed effects model was used to develop the population pharmacokinetic model and investigate the influence of these polymorphisms and other patient specific covariates on the pharmacokinetics of tenofovir. RESULTS: The estimated glomerular filtration rate calculated by the Cockcroft and Gault equation, concomitant use of lopinavir/ritonavir and ABCC4 3463A>G polymorphism were associated with tenofovir apparent oral clearance (CL/F)...

BACKGROUND: Ceftriaxone (CTRX) is a known cause of biliary pseudolithiasis (BPL) mainly in children. Biliary elimination of CTRX increases in patients with renal dysfunction. However, the influence of renal dysfunction on the incidence of CTRX-associated BPL has not been well investigated. The aim of this study was to investigate the cumulative incidence of CTRX-associated BPL in adults and to assess if renal dysfunction is a risk factor. METHODS: We retrospectively analyzed the medical records of 478 patients treated with CTRX to assess the incidence and risk factors of CTRX-associated BPL...
