Background: Carbon dioxide (CO2) is a by-product of cellular metabolism, which could be considered as a reflection of metabolism, circulation, and ventilation. Arterial blood gas analysis (ABG) is the gold standard of monitoring for CO2. However, is an expensive method leading to blood loss and iatrogenic anemia. In addition, each sample is only a...

Background Bleeding is one of the most common complications of craniosynostosis surgery, which its appropriate management is associated with better post-operative outcomes. The aim of this retrospective study was to evaluate the visual estimated blood loss in intraoperative management of infants with craniosynostosis surgery. Materials and Methods This retrospective study was performed on 200 p...

BACKGROUND AND PURPOSE A right-to-left shunt can be identified by contrast transcranial Doppler ultrasonography (c-TCD) at rest and/or after a Valsalva maneuver (VM) or by arterial blood gas (ABG) measurement. We assessed the influence of controlled strain pressures and durations during VM on the right-to-left passage of microbubbles, on which depends the shunt classification by c-TCD, and corr...

abstract posttraumatic intravasation of fat and debris can lead to a cascade of events. hydroxyethyl starches (hes) markedly suppress neutrophil influx by decreasing pulmonary capillary permeability and facilitating tissue oxygenation by improving microcirculation. it was hypothesized that in hypoxemic femur injury patients undergoing operative stabilization, hes administration will prevent the...

conclusions comparing the serum lactate level before operation and 24 hours after the operation showed that the number of received blood units had a significant effect on serum lactate. we found no significant effect for blood storage duration; however, the number of given blood units was more significant. patients and methods in a cross-sectional study, 228 patients referred to three hospitals...

Abstract Background Measurement of arterial CO2 (PaCO2) is the gold standard for diagnosis sleep hypoventilation during polysomnography. However, PaCO2 measurement a labour-intensive and painful. Previous audit in our unit demonstrated ABGs are often delayed or omitted when requested. Continuous monitoring transcutaneous carbon dioxide (TcCO2) used as surrogate marker PaCO2, however caution sho...

Definition of Respiratory Failure using PaO2 alone is confounded when patients are commenced on oxygen therapy prior to arterial blood gas (ABG) measurement. Furthermore, classification of Respiratory Failure as Type 1 or Type 2 using PaCO2 alone can give an inaccurate account of events as both types can co-exist. 100 consecutive presentations of acute respiratory distress were assessed initial...

INTRODUCTION Prevention of pulmonary complications after coronary artery bypass graft is attended as a very important issue. The aim of this study was to evaluate the role of pulmonary rehabilitation before surgery for reducing the risk of pulmonary complications after surgery. METHODS In a randomized clinical trial, 60 patients undergoing heart surgery were randomly divided into two groups A...
