Given differences in sympathetic innervation to glabrous and nonglabrous skin, we tested the hypothesis that muscle metaboreceptor regulation of cutaneous vascular conductance (CVC) differs between these skin regions. Subjects (n = 21) performed isometric handgrip exercise (IHG; 50% maximal voluntary contraction for 60 s), followed by 2 min of postexercise ischemia. Throughout IHG and postexerc...

PURPOSE To assess the proximal humerus intraosseous (PHIO) catheter placement as a preferred method for venous access over conventional methods, including peripheral intravenous (PIV) and central venous catheters (CVCs), during emergency room resuscitation. METHODS In phase 1, conventional methods for venous access (PIV and CVC) were assessed for all patients presenting to the emergency depar...

BACKGROUND Various methods have been recommended to decide a proper insertion depth of central venous catheter (CVC). The carina is recommended as a useful target level for the CVC tip position. We evaluated the sternal head of a right clavicle and the nipples as anatomic landmarks for determining the optimal depth of CVC in paediatric patients. METHODS Ninety children, <5 yr, undergoing cath...

OBJECTIVES The use of ultrasound (US) has been shown to improve success rates and reduce complications of central venous catheter (CVC) placement in adult emergency department (ED) patients. The authors sought to determine if US assistance for CVC placement is associated with an increased success rate in pediatric ED patients. METHODS This was a retrospective cohort study of CVC placement in ...

Plasmodium vivax produces numerous caveola-vesicle complex (CVC) structures beneath the membrane of infected erythrocytes. Recently, a member helical interspersed subtelomeric (PHIST) superfamily protein, PcyPHIST/CVC-8195, was identified as CVCs-associated protein in Plasmodium cynomolgi and essential for survival of this parasite. Very little information has been documented to date about PHIS...

Drs. Schulz-Stübner and Schummer are correct in that we did not mention electrocardiogram positioning as a tool to verify correct positioning of a central venous catheter (CVC). However, our goal was to increase awareness of how to prevent CVC-induced cardiac tamponade by positioning the CVC tip outside the pericardial reflection. Electrocardiogram-guided CVC positioning places the CVC tip at t...

A fractured central venous catheter (CVC) with embolization of the distal fragment may lead to life-threatening complications. We had inserted a right subclavian CVC in a 68-year-old female which upon a follow-up chest X-ray appeared to have been sheared. A guidewire was inserted through the CVC until the J-tip was just beyond the tip of the CVC which were then withdrawn as a single assembly. W...

Connected Vertex Cover Problem (CVC) is an NP -hard problem. The currently best known approximation algorithm for CVC has performance ration 2. This paper gives the first Polynomial Time Approximation Scheme for CVC in Unit Disk Graph.

Children with diabetic ketoacidosis (DKA) may require central venous catheters (CVC) for fluid resuscitation. CVC-related thrombus has been reported in a variety of conditions but only rarely in association with DKA and never in a child under one. The case of a five week old child with DKA and a CVC-related thrombus is presented.
