Objective: Fluid resuscitation is necessary in almost all critical patients. The central venous pressure (CVP) is a well-established method of assessing resuscitation. Recently, there have been attempts to investigate less invasive methods like the diameters of inferior vena cava (IVC) or the jugular vein. We aimed to investigate this method in our research.Methods: Seventy eight critical...

OBJECTIVE To explain why investigations of the measurement of central venous pressure (CVP) usually reveal a discrepancy between the clinician's estimate of CVP from physical diagnosis and supine measurement with a catheter. Data from MEDLINE search, personal files, and bibliographies of textbooks on physical diagnosis and cardiology were used. RESULTS The most important reasons for this disa...

A single i.p. administration of 1.0 mg/kg of chlorphenvinphos (CVP), an organophosphorus pesticide, results in an acute stress response, evidenced by a marked (6-7 fold) rise in plasma corticosterone (CORT) concentration, and a diminished behavioural sensitivity to amphetamine (AMPH) three weeks postexposure. Surprisingly, in rats subjected to a single series of inescapable electric footshocks ...

PURPOSE Although rituximab (R) is commonly used for patients with advanced follicular lymphoma (FL) requiring treatment, the optimal associated chemotherapy regimen has yet to be clarified. PATIENTS AND METHODS We conducted an open-label, multicenter, randomized trial among adult patients with previously untreated stages II to IV FL to compare efficacy of eight doses of R associated with eigh...

introduction:the assessment of intravascular volume in severely traumatized patients or patients admitted in icu is very essential. at present the accurate method for estimating the intravascular volume requirement is by measuring the cvp which is an invasive method. the measurement of ivc diameter by ultrasound has been suggested as an easily available and simple method for measuring the intra...

between CVP and indexes of fluid responsiveness might be influenced by ongoing fluid losses or gains that were not necessarily easily measurable. Finally, in many clinical situations, the success or failure of fluid resuscitation measures is not determined by preset goals in terms of cardiac output or other indexes of cardiac performance but by criteria such as pressor requirements or blood lac...

We use pruned enumeration algorithms to find lattice vectors close to a specific target vector for the prime number lattice. These algorithms generate multiplicative prime number relations modulo N that factorize a given integer N . The algorithm New Enum performs the stages of exhaustive enumeration of close lattice vectors in order of decreasing success rate. For example an integer N ≈ 10 can...

Even though Public Key Infrastructure (PKI) and X.509 certificate has been a prominent security model for a variety of e-commerce applications and large scale distributed computing, it has not been sufficiently investigated in the certificate revocation and verification mechanism. In this paper, we discuss the need and importance of certificate revocation and verification, and analyze the limit...

The concept that a specific level of central venous pressure (CVP) limits man's adjustment to heat stress has been debated. Evidence was presented that identifies a true limit of adjustment as being more related to factors affecting evaporative cooling, such as level of hydration, release of active vasodilation substance (AVS), and sweat gland fatigue. However, it was conceded that decreases in...
