“…Body mass index (BMI), indication for central venous access, site of vascular trauma, type of catheter, coagulation parameters, and operators are described in Table 1. Seven patients [2,3,4,5,7,8,10] were obese with a BMI > 30. One patient [9] had an athletic stoutness with marked development of the pectoral and scalenius muscles.…”

“…One patient [9] had an athletic stoutness with marked development of the pectoral and scalenius muscles. Nine patients [1,2,3,5,6,7,8,10,11] presented with an acute episode of renal failure at the time of the procedure, two [4,6] suffered from heart failure and one [9] had a severe brain, chest, and abdominal trauma. Thromboplastin levels and platelet counts were markedly depressed in 5 patients.…”

“…Thromboplastin levels and platelet counts were markedly depressed in 5 patients. These coagulation impairments related to recent heart surgery [6], liver transplantation [7], liver and spleen lacerations [9], renal transplantation [1,2], and hemolytic±uremic syndrome [11]. In all cases, board-certified intensivists, eight senior fellows and three staff members carried out the procedure.…”

The purpose of this retrospective study was to report 11 cases of severe vascular complications after central venous catheter misplacement. For each patient, data collection included body mass index, the diagnosis at admission, the site of the procedure, the type of catheter, coagulation parameters, the imaging modalities performed and the applied treatment. Eight patients had a lesion of the subclavian artery. Brachiocephalic vein perforations were assessed in three more patients. All patients had a chest roentgenogram after the procedure, six a CT examination, and four an angiographic procedure. Seven patients had a body mass index above 30, and 5 patients had coagulation disorders prior to the procedure. Seven patients were conservatively managed, 2 patients died despite resuscitation, 1 patient was treated with a stent graft, and one by superselective embolization. Subclavian or jugular vein temporary catheter positioning is a practical approach. Identification of any iatrogenic perforation of the subclavian artery or central veins urges obtaining a chest roentgenogram and, when required, a chest CT, selective angiograms or venograms. Body mass index superior to 30, previous unsuccessful catheterization attempts, and coagulation factor depletion seemed to account for risk factors. Recognition of clinical and radiological complications is mandatory.

ÖzetSantral venöz kateter uygulaması, özellikle yoğun bakım ünitesinde takip edilen ve majör cerrahi planlanan hastalarda yaygın olarak kullanılan küçük bir cerrahi girişimdir. Genellikle hasta yatak başında lokal anestezi ile uygulanır.Küçük bir girişim olmasına rağmen hatalı uygulamalar sonucu ciddi komplikasyonlara neden olabilmektedir. Bu konuda uzmanlaşmış kişiler tarafın-dan uygulandığında komplikasyon oranları azalmaktadır. En sık karşılaşılan komplikasyon malpozisyondur. Malpozisyonlar uygulama hatası sonucu gelişir. Bu makalede amacımız; özellikle sık kullanılması nedeniyle, subklavian kateter uygulama hataları ve dikkat edilmesi gereken teknik konuları ortaya çıkarmaktır. Anahtar KelimelerKateter; Malpozisyon; Teknik AbstractCentral venous catheter application is a minor surgical procedure for patients in care unit and for patients who was planned for major operation. This procedure performs commonly on bad side with local anesthesia. In spite of minor surgical procedure, it can cause serious complications due to technical mistakes. The complications rate decrease if the professional person performed. The malposition is the most common complication. It generally associated with application mistakes. The aim of this article is to uncover the mistakes of subclavian catheter application that used commonly and the technical procedure to take care.

The aim of this study was to evaluate the potential of carboxymethyl chitosan (CM‐chitosan) nanoparticles as carriers for the anticancer drug, doxorubicin (DOX). Different kinds of CM‐chitosan with various molecular weight (MW) and degree of substitution (DS) were employed to prepare nanoparticles through ionical gelification with calcium ions. Factors affecting nanoparticles formation in relation to MW and DS of CM‐chitosan were discussed. By the way of dynamic light scattering (DLS), TEM, and atomic force microscopy (AFM), nanoparticles were shown to be around 200–300 nm and in a narrow distribution. FTIR revealed strong electrostatic interactions between carboxyl groups of CM‐chitosan and calcium ions. DOX delivery was affected by the molecular structure of CM‐chitosan. Increasing MWs of CM‐chitosan from 4.50 to 38.9 kDa, DOX entrapment efficiency was enhanced from 10 to 40% and higher DS slightly improved the load of DOX. In vitro release studies showed an initial burst followed by an extended slow release. The DOX release rate was hindered by CM‐chitosan with high MW and DS. These preliminary studies showed the feasibility of CM‐chitosan nanoparticles to entrap DOX and the potential to deliver it as controlled release nanoparticles. © 2006 Wiley Periodicals, Inc.
