Do we need to monitor cardiac output during major surgery?
1151 December 2012 T is strong evidence that optimizing stroke volume or cardiac output during major surgical procedures is associated with better outcomes.1–3 With this approach, interventions, consisting primarily of fluid administration, are given until there is no further increase in stroke volume, that is, when the FrankStarling relation reaches a plateau. In this issue of ANESTHESIOLOGY, ...
متن کاملAn Integrated ISFET Sensor Array
A monolithically integrated ISFET sensor array and interface circuit are described. A new high-density, low-power source-drain follower was developed for the sensor array. ISFETs were formed by depositing Au/Ti extended-gate electrodes on standard MOSFETs, then thin silicon nitride layers using catalytic chemical vapor deposition and/or SU-8 protective layers were formed on the extended-gate el...
متن کاملA comparison of the non-invasive ultrasonic cardiac output monitor (USCOM) with the oesophageal Doppler monitor during major abdominal surgery.
BACKGROUND Perioperative interventions, targeted to increase global blood flow defined by explicit measured goals, reduce postoperative complications. Consequently, reliable non-invasive estimation of the cardiac output could have far-reaching benefit. METHODS This study compared a non-invasive Doppler device - the ultrasonic cardiac output monitor (USCOM) - with the oesophageal Doppler monit...
متن کاملCongenital Hypofibrinogenemia Detected during Preoperative Workup for Major Cardiac Surgery
Afibrinogenemia or hypofibrinogenemia is a quantitative defect in fibrinogen. It is a rare disease with estimated frequency of 1 in 1,000,000 population. Routine preoperative screening tests of coagulation disorders are insufficient to detect subtle disorders of fibrinogen. Herein, we report a child who was supposed to undergo open cardiac surgery for a large atrial septal defect. Preoperative ...
متن کاملThe ion sensitive field effect transistor (ISFET) pH electrode: a new sensor for long term ambulatory pH monitoring.
Intraluminal pH monitoring in man should be performed with disposable multichannel assemblies that allow recordings at multiple sites and prevent transmission of infection. Currently available glass electrodes are unsuitable for this purpose because of their size and price. We have thus constructed and tested a small, combined ion sensitive field effect transistor (ISFET) pH electrode incorpora...
