The efficacy of single suture for exit site wound closure and stabilization of hemodialysis central tunneled catheter

2021

Introduction: The majority of the end-stage renal disease patients begin hemodialysis with the central tunneled catheter as a permanent or bridge vascular access. The procedure of central tunneled catheter insertion can be complicated by exit site bleeding, prolonged tunnel healing, and infection. The study aimed at evaluating whether the catheter exit site wound closing with a single-suture method is equally effective as the double suture method, which is most frequently applied. The assumption was that the single-suture method, which is less traumatizing for the skin, could offer an advantage for the patients with “paper” skin, that is, elderly, after long-term immunosuppressive treatment…

Development of a long-lasting ventricular catheter impregnated with a combination of antibiotics.

2003

A ventricular silicone catheter impregnated with a combination of rifampin and a quinolone was developed in order to prevent ventricular shunt related infections. As model substance for the quinolones we used sparfloxacin, because of its specific physicochemical properties resulting in a quantitative detection also in the presence of a second antibiotic. In our study we focused especially on an optimization of the antibiotic release out of the impregnated catheters in order to develop long lasting devices with a broad antimicrobial spectrum. A release-optimized catheter was tested with an in vitro colonization test and additionally with a method developed to examine the spread of bacteria o…

Direct true lumen cannulation in type A acute aortic dissection: A review of an 11 years’ experience

2020

ObjectivesDirect true lumen cannulation (DTLC) of the aorta is an alternative cardiopulmonary bypass cannulation technique in the context of type A acute aortic dissection (A-AAD). DTLC has been reported to be effective in restoring adequate perfusion to jeopardized organs. This study reports and compares operative outcomes with DTLC or alternative cannulation techniques in a large cohort of patients with A-AAD.MethodsAll patients who underwent surgery for A-AAD between January 2006 and January 2017 in Mainz university hospital were reviewed. The choice of cannulation technique was left to the operating surgeon, however DTLC was our preference in patients who were in state of shock or showe…

Non-invasive tunnelled catheter reposition (NTCR): A simple and safe method to restore central tunnelled catheter function for haemodialysis

2020

AbstractDespite all efforts, still many end-stage kidney disease (ESKD) patients are dialysed using a central tunnelled catheter (CTC) as vascular access. When the CTC blood flow becomes ineffective, a number of protocols are advised. However, all of them are time- and cost-consuming. The manoeuvre of a non-invasive tunnelled catheter reposition (NTCR) was introduced to restore the CTC function. NTCR was based on gentle movements of the CTC, with or without a simultaneous flushing of the CTC lines, which resulted in a quick reposition of the CTC tip. This study comprises the analysis of a total of 297 NTCRs, which were performed in 114 patients, thus enabling an effective blood flow after 1…

Problem-based learning for anesthesia resident operating room crisis management training.

2018

Background Senior anesthesia residents must acquire competency in crisis management for operating room (OR) emergencies. We conducted problem based learning (PBL) OR emergency scenarios for anesthesia residents, focused on emergencies in ‘Airway’, ‘Circulation’, ‘Central venous catheter’, and ‘Pain management complications’. Non-technical skills are an integral component of team-based OR emergency management. Methods Prior to integrated OR emergency clinical and non-technical skills PBL training, participating 35 anesthesia residents completed two 5-point scale surveys regarding frequency of emergency experiences in the operating room, and self-confidence for anesthesia-related crisis manag…

Effect of a surveillance system for decreasing neonatal nosocomial infections.

2018

Nosocomial infection in very low birthweight (VLBW) infants is a common complication with high morbimortality. New strategies to reduce its occurrence have recently led to the development of neonatal surveillance programs.To determine whether the NeoKissEs surveillance system implementation in our neonatal unit has been associated with a decrease in nosocomial infection in VLBW infants, as well as a reduction in the use of antibiotics and central venous catheters (CVC).Retrospective and descriptive study of infants1500 g admitted between January 2011 and December 2017. Rates of use of antibiotics and CVC were calculated, as well as late-onset sepsis incidence. Data were compared before and …

Tunnelled Haemodialysis Catheter Removal: An Underappreciated Problem, Not Always Simple and Safe

2020

Background: Optimal care of patients treated with a central tunneled catheter (CTC) as vascular access for hemodialysis requires a number of procedures. One of them is CTC removal, usually carried out using mostly the cut-down method (CDM) and the traction method (TM). The procedure seems to be simple and safe
