Postoperative Costs Associated With Outcomes After Cardiac Surgery With Extracorporeal Circulation: Role of Antithrombin Levels
2012
Objective: To study the impact on postoperative costs of a patient's antithrombin levels associated with outcomes after cardiac surgery with extracorporeal circulation. Design: An analytic decision model was designed to estimate costs and clinical outcomes after cardiac surgery in a typical patient with low antithrombin levels (= 63.7%). The data used in the model were obtained from a literature review and subsequently validated by a panel of experts in cardiothoracic anesthesiology. Setting: Multi-institutional (14 Spanish hospitals). Participants: Consultant anesthesiologists. Measurements and Main Results: A sensitivity analysis of extreme scenarios was carried out to assess the impact o…
Troponin I concentrations of shed blood might influence monitoring of myocardial injury after coronary operations.
2002
Abstract In a prospective study we evaluated the concentration of cardiac troponin I (cTnI) and creatine kinase activities (CK) in shed mediastinal blood in the early postoperative period after coronary artery bypass grafting (CABG). Forty seven patients who underwent first time elective CABG were studied. CTnI levels and CK activities in arterial blood and shed mediastinal blood were measured after admission to the intensive care unit (ICU) and 6 h after unclamping the aorta. Mediastinal shed blood samples were drawn from 23 patients (group A) before the filter of the cardiotomy reservoir and from 24 patients (group B) behind. Additionally, both markers were measured in blood samples colle…
Role of high-resolution ultrasound in guiding treatment of idiopathic plantar fasciitis with minimally invasive techiniques
2007
The aim of this study was to assess the reliability of peri-fascial oedema as a sonographic criterion for selecting the most appropriate treatment (ultrasound-guided corticosteroid injection or ultrasound-guided extracorporeal shock wave therapy) of idiopathic plantar fasciitis (IPF).Sixty-four patients with a clinical diagnosis of unilateral refractory IPF, treated conservatively for at least 8 weeks, were studied with high-resolution ultrasound (HRUS). Pain intensity was evaluated with a visual analogue scale (VAS). HRUS was used to confirm IPF and identify the presence of peri-fascial oedema. Patients with an HRUS diagnosis of IPF were grouped according to the presence (A) or absence (B)…
The control of anti-coagulation in acute dialyses with sensitive laboratory parameters.
1992
In seven patients who had to be dialysed between four and 13 times due to acute renal failure, low molecular weight heparin (LMWH) Fragmin was used for anticoagulation. According to dose-finding studies, 80-90 U kg-1 body weight of LMWH as a single bolus were administered initially, producing dose-related levels of 0.3-1.5 anti-factor Xa U ml-1 in plasma. Apart from the anti-Xa activity in the plasma, the thrombin anti-thrombin III complex (TAT complex) and a fibrin degradation product (D-dimer) were measured as parameters of a coagulation activation. A sufficient anti-coagulation during dialysis was supposed to exist at a normal range (5.0 micrograms l-1 or below) of TAT complex. Pathologi…
Management of retained bile duct stones: a prospective open trial comparing extracorporeal and intracorporeal lithotripsy.
1996
Abstract Background: Endoscopic management of common bile duct stones has become the approach of choice, especially in patients with high surgical risk. Problems are encountered if there are large stones or a duct stenosis. For these difficult stones, shock wave technology serves as an alternative to surgical intervention. Methods: A total of 125 patients with common bile duct stones in whom conventional endoscopic treatment had failed were selected and treated either by extracorporeal piezoelectric lithotripsy (ESWL, n=79) or intracorporeal electrohydraulic lithotripsy (EHL, n=46). The average age of our patients was 70 years. Results: In the ESWL group visualization of the stones by ultra…
Rheopheresis in Patients with Critical Limb Ischemia--Results of an Open Label Prospective Pilot Trial
2005
Rheopheresis is a specifically designed application of double filtration plasmapheresis, for extracorporeal treatment of microcirculatory disorders. Safety and efficacy of Rheopheresis for wound healing and skin oxygenation were investigated in patients with critical limb ischemia. Twelve patients of Fontaine stage III-IV were treated with a series of 10 Rheopheresis sessions over 17 weeks. Transcutaneous oxygen pressure (tcpO(2)) and ankle-brachial index (ABI) were repeatedly determined to monitor the effects of the Rheopheresis treatment series on microcirculation and skin blood flow. Laboratory parameters of blood rheology were measured in addition to safety parameters and course of the …
Rheopheresis in patients with ischemic diabetic foot syndrome: results of an open label prospective pilot trial.
2003
: Rheopheresis is a specific application of membrane differential filtration, synonymous with double filtration plasmapheresis, for extracorporeal hemorheotherapy. Safety and efficacy of Rheopheresis for wound healing and skin oxygenation were investigated in patients with ischemic diabetic foot syndrome. Eight patients with type 2 diabetes mellitus and non-healing foot ulcers caused by severe ischemic diabetic foot syndrome were treated by a series of seven Rheopheresis sessions in a time span of 11 weeks. Wound healing had not been detectable under conditions of standardized wound care during at least 2 months. Wound status was classified by its morphology, severity and location, accordi…
Outcomes after extracorporeal membrane oxygenation for the treatment of high-risk pulmonary embolism: a multicentre series of 52 cases
2018
International audience; Aims The role of extracorporeal membrane oxygenation (ECMO) remains ill defined in pulmonary embolism (PE). We investigated outcomes in patients with high-risk PE undergoing ECMO according to initial therapeutic strategy. Methods and results From 01 January 2014 to 31 December 2015, 180 patients from 13 Departments in nine centres with high-risk PE were retrospectively included. Among those undergoing ECMO, we compared characteristics and outcomes according to adjunctive treatment strategy (systemic thrombolysis, surgical embolectomy, or no reperfusion therapy). Primary outcome was all-cause 30-day mortality. Secondary outcome was 90-day major bleeding. One hundred a…
Low-frequency extracorporeal shock wave lithotripsy improves renal pelvic stone disintegration in a pig model.
2009
OBJECTIVE To compare disintegration rates for renal stones treated by 60 vs 120 shock waves (SW)/min at the same energy settings, using standardized validated artificial stones in a pig model. MATERIALS AND METHODS Gypsum artificial stones (13 × 6 mm) were inserted into the renal pelvis on either side of 12 anaesthetized pigs by open surgery. Extracorporeal SW lithotripsy (ESWL) was applied using a new electromagnetic lithotripter (Lithoskop®, Siemens AG Healthcare, Munich, Germany) at 60 and 120 SW/min; 3000 SW were applied to each kidney with the same energy settings. Stone fragments were collected after nephrectomy, passed through calibrated test sieves, and weighed. Fragment size catego…
Surgical aspects of urolithiasis in children.
1991
Operative management of renal calculi has changed radically in the last decade. New operative techniques. the use of intra-operative ultrasound and Doppler sonography have even made possible the removal of complete staghorn calculi in short and kidney-preserving procedures. The introduction of percutaneous nephrolithotomy and stone extraction using a specially designed ureteroscope and, above all, the clinical application of extracorporeal shock wave lithotripsy have made stone surgery less invasive and have provided a higher rate of preservation of kidney function.
