BACKGROUND Venoveno bypass (VVB) has been used to achieve hemodynamic stability and decrease the incidence of renal dysfunction. However, VVB has many complications. The purpose of this study is to verify the safety of total clamping of the suprahepatic inferior vena cava (IVC) without VVB during orthotropic liver transplantation (OLT) in terms of anesthetic management. METHODS Twenty-five pa...

ACUTE ISCHEMIA AND HYPERTENSION Hill records that both Poiseuille and Magendie observed acceleration of pulse and a rise of blood pressure in animals following ligation of both carotids, but gives no references. Nawalichin records that clamping the common carotids in anesthetized cats causes a rise in blood pressure; Hill in rabbits and Stewart et al. in dogs, among many subsequent workers, mad...

TPIF-RL method is a new that gives better wall thickness in incremental forming. In this method, the sheet not fixed at edges. Like deep drawing process, it compressed with certain pressure. During forming flows under blankholder. Thus, more homogenous ob-tained.In study, Titanium Grade 2 formed as cone via method. Optimum parameters were determined by Signal/Noise analysis. addi-tion, finite e...

Highlights The article describes the first conducted pseudorandomized comparative study of mitral valve replacement using either traditional or “valve-in-valve” techniques. Abstract Aim. To compare short-term (perioperative) and medium-term (6 months) outcomes surgical treatment bioprosthetic dysfunction methods. Methods. included 18 patients undergoing (open replacement) chosen according to fo...

The timing of the umbilical cord clamping at birth is still controversial. In the modern era of medicine, the cord has been clamped early to facilitate resuscitation and stabilization of infants. However, recently delayed cord clamping has been supported by physicians because it allows for the physiological transfer of blood from the placenta to the infant. Many clinical studies have revealed t...

We analyze a class of mechanisms that locomote by switching between constraints. Because of the hybrid nature of such systems, most of the existing analysis tools, developed primarily for smooth systems, can not be directly applied. Our aim is to exploit the special structure provided by Lagrangian mechanics to study the controllability of this class of mechanisms. We base the analysis on a ser...

This paper shows ongoing research results on the development of automatic control modes for robotized laparoscopic surgery. We show how both force feedback and visual feedback can be used in an hybrid control scheme to autonomously perform basic surgical subtasks. Preliminary experimental results on an example clamping tasks are given.

BACKGROUND Policies for timing of cord clamping vary, with early cord clamping generally carried out in the first 60 seconds after birth, whereas later cord clamping usually involves clamping the umbilical cord more than one minute after the birth or when cord pulsation has ceased. The benefits and potential harms of each policy are debated. OBJECTIVES To determine the effects of early cord c...

The optimal time for umbilical cord clamping after birth remains a critical unknown fact that has implications for the infant, the mother, and science. A national survey was conducted using a randomized sample (n = 303) of the active membership of the ACNM to determine cord clamping practices and beliefs of American nurse-midwives. The response rate was 56%. The respondents fell into three cord...

BACKGROUND Recent experimental physiology data and a large, population-based observational study have changed umbilical cord clamping from a strictly time-based construct to a more complex equilibrium involving circulatory changes and the onset of respirations in the newly born infant. However, available evidence is not yet sufficient to optimize the management of umbilical cord clamping. FIN...
