Filter by:Laparoscopic Hepatectomy (LH) is an important treatment for liver diseases, and bleeding is one of the most common complications during dissection of the liver parenchyma. Control Low Central Venous Pressure (CLCVP) technique is currently one of the most important techniques to control intraoperative bleeding. It mainly consists of fluid restriction, position adjustment and use of vasodilators. However, these measures focus on decreasing CVP by reducing the volume of return blood, and less attention is paid to factors such as pulmonary vascular resistance and cardiac function. Sildenafil, known as Viagra, is currently used to treat erectile dysfunction and pulmonary hypertension in men. Its mechanism of action is to inhibit phosphodiesterase-5 (PDE-5) and increase cGMP levels leading to smooth muscle relaxation and vasodilation. Its pharmacological properties provide potential value for the treatment of many diseases. However, few studies have been conducted both domestically and internationally on the use of sildenafil citrate in LH related to CLCVP. The aim of this study is to investigate the following aspects: 1) the feasibility and effectiveness of sildenafil citrate applied to control low central venous pressure in LH, such as intraoperative bleeding, the impact of CVP, and the surgeon's operative field grading to assess the value of its clinical application; 2) the impact of sildenafil citrate applied to the function of the liver and important organs of the kidneys of the patients after LH surgery as well as the incidence of postoperative complications, and to assess the clinical application of its Safety.
The study is aimed at comparing peripherial venous pressure as an indicator of central venous pressure in post operative surgical patients.
This study evaluates the accuracy of a comprehensive venous Doppler echography including the portal vein pulsatility index (PVPI) to quantify invasively measured right-sided venous pressures. A substudy will correlate invasive and non-invasive hemodynamic measurements to ballistocardiography and seismocardiography with the Kino-cardiograph (Kino) device (HeartKinetics, Waterloo, Belgium).
While central venous pressure measurement is used to guide fluid management in high risk surgical patients during perioperative period, the relationship between the value of central venous pressure and organ dysfunction and prognosis of high-risk operating patients is unknow. In this study, we conducted a retrospective study of the relationship between the initial levels of CVP with organ dysfunction, the severity of illness, the length of ICU stay, and prognosis of critically ill patients.
This is a prospective, comparative, internally controlled device study that will enroll a total of 100 adult patients that require the placement of central venous catheter and CVP monitoring to assess volume status and cardiac preload.
Recent studies indicated the central venous pressure (CVP) as a prognostic marker. Therefore, we retrospectively analyzed the CVP on admission to the intensive care unit (ICU) in cardiac surgery patients regarding its prognostic value for morbidity and mortality.
The goal of this research study is to determine the feasibility and accuracy of Mespere Life Science non-invasive central venous pressure monitoring system (Mespere VENUS 2000CVP system) in children with congenital heart disease (CHD).
The purpose of this study is to establish the accuracy of a non-invasive device that uses near infrared spectroscopy (NIRS) to estimate central venous pressure (CVP) comparing it to physical exam and invasive hemodynamic measurement via right heart catheterization (RHC).
The primary objective of this study is to determine whether a correlation exists between the Mespere Non-Invasive Central Venous Pressure (NICVP) device for measuring central venous pressure (CVP), and assessment of CVP via physical examination.
This protocol is a prospective interventional pilot study at the Children's Hospital of Philadelphia to determine whether or not two increments of sternal pressure known to occur during "leaning" in CPR affects hemodynamic function, coronary perfusion pressures, and intrathoracic pressure in order to inform the resuscitation community on reasonable target pressures to avoid "leaning" on the chest during pediatric CPR.
