Pharmacokinetics and pharmacodynamics of hydroxyethyl starch in hypovolemic pigs; a comparison of peripheral and intraosseous infusion.
1999
Intraosseous (i.o.) infusion is considered a useful technique for the administration of medications and fluids in emergency situations when peripheral intravascular access is not possible. This study investigated the effectiveness of i.o. versus intravenous (i.v.) infusion of hydroxyethyl starch (HES 200/0.5) in hypovolemic pigs. Twenty-three pigs (8- to 9-week-old) were anaesthesized, instrumented and blood was withdrawn (25-30 ml/kg) to50 mmHg mean arterial pressure (MAP). The animals were left untreated in haemorrhage for 30 min. Relevant haemodynamic parameters were monitored and blood samples were collected for blood gas and HES concentration analysis. Infusion of HES via i.v. or i.o. …
Plasticizer extraction of Taxol infusion solution from various infusion devices.
1996
Taxol solution extracts the plasticizer DEHP (di(2-ethylhexyl)phthalate) from polyvinyl chloride (PVC) materials. In order to minimize patient exposure to DEHP, Taxol solutions should be prepared and administered in PVC-free materials. Particulate matter may form in Taxol infusion solution over time, so that in-line filtration with microporous membranes not greater than 0.22 microns is advisable. The purpose of this study was to evaluate the suitability of various administration- and in-line filter-sets for Taxol application. The extent of leached DEHP was determined using a Reversed Phase HPLC assay specific for DEHP. The four tested administration-sets, labeled as PVC-free, were all found…
By Way of Another Editorial on Fusions in the Digital and Public Humanities
2020
This second issue of magazén closes the inaugural volume 2020 and thematically follows high on the heels of the first one, as they are both connected to the topic of ‘fusions’, a term which in our intentions functions as a picklock to investigate recent developments in the wider field of digital and public humanities.
Root damage induced by intraosseous anesthesia'An in vitro investigation
2012
Objectives: The principle of the intraosseous anesthesia (IOA) relies on the perforation of the cortical plate of the bone for direct application of the local anesthetic solution into the underlying cancellous structures. During this procedure, IOA needles might accidentally come in contact with the tooth roots. The aim of the current in vitro study was to examine the consequences of this ‘worst case scenario’ comparing five commercially available IOA systems. Material and Methods: Extracted human roots were randomly perforated using five different IOA systems with a drilling time ≤5s. To simulate normal in vivo conditions, the roots were kept humid during the drilling procedure. Data was s…
On the anti-inflammatory and anti-phospholipase A2 activity of extracts from lanostane-rich species
2000
Abstract We have studied extracts from three species rich in lanostane triterpenes for their activity against different in vivo models of inflammation induced by TPA, EPP and PLA2. The inhibitory effect against PLA2 in vitro was also studied. When the Poria cocos extract was tested against PLA2-induced mouse paw edema, it was active by the oral and parenteral routes. Its effect was greater in both magnitude and duration than that of Pistacia terebinthus and Ganoderma lucidum extracts. P. terebinthus was effective against chronic and acute inflammation, and according to a preliminary chromatographic analysis, its seems to be a good source of lanostane anti-inflammatory agents. G. lucidum was…
Rationale and Design of the Efficacy of a Standardized Diuretic Protocol in Acute Heart Failure Study
2021
AIMS: Although acute heart failure (AHF) with volume overload is treated with loop diuretics, their dosing and type of administration are mainly based upon expert opinion. A recent position paper from the Heart Failure Association (HFA) proposed a step-wise pharmacologic diuretic strategy to increase the diuretic response and to achieve rapid decongestion. However, no study has evaluated this protocol prospectively. METHODS AND RESULTS: The Efficacy of a Standardized Diuretic Protocol in Acute Heart Failure (ENACT-HF) study is an international, multicentre, non-randomized, open-label, pragmatic study in AHF patients on chronic loop diuretic therapy, admitted to the hospital for intravenous …
Human pasteurized C1-inhibitor concentrate for the treatment of hereditary angioedema due to C1-inhibitor deficiency.
2011
Hereditary angioedema is a relatively rare genetic disorder affecting between one in 10,000 and one in 50,000 individuals worldwide. The most common clinical symptoms observed are relapsing swelling of the skin and abdominal pain attacks. However, more serious and potentially fatal laryngeal attacks can also occur. Hereditary angioedema is most frequently caused by a deficiency of C1-inhibitor. Replacement therapy with Berinert, an intravenous pasteurized C1-inhibitor concentrate derived from human plasma, is a recommended treatment for rapid resolution of acute attacks of hereditary angioedema due to C1-inhibitor deficiency. Prophylactic therapy with C1-inhibitor is also available. Future …
The Evolution of Hemophilia Care: Clinical and Laboratory Advances, Opportunities, and Challenges
2020
AbstractHemophilia A (HA) and B (HB) are X-linked bleeding disorders caused by mutations in the F8 or F9 gene that result in the absence, or reduced activity, of the corresponding clotting factor. The severity of bleeding and related complications is proportional to the amount of residual circulating functional factor. The development of a safe and effective hemophilia treatment lasted several decades and has been mainly based on clotting factor replacement. Advances in the engineering and manufacturing of clotting concentrates have led to the widespread availability of extended half-life products that reduced the number of intravenous infusions needed to achieve adequate trough levels. The…
Multifocal disseminated lipoatrophy secondary to intravenous corticosteroid administration in a patient with adrenal insufficiency.
2002
Multifocal disseminated lesions of circumscribed lipoatrophy have not been described as an adverse reaction of intravenously applied drugs. A unique patient with adrenal insufficiency is reported who received corticosteroids intravenously and then had multiple lesions develop that were similar to focal lipoatrophy as known to occur secondary to faulty intradermal injections of corticosteroids.
