- Primary Outcome Measures
Name Time Method 1.We aimed to compare invasive hemoglobin (Hb) values versus non-invasive Hb values at the trigger point for blood transfusion [9 gm%]. <br/ ><br> <br/ ><br>Timepoint: The non-invasive hemoglobin monitoring [SpHb®] probe will be applied to the patient immediately after the induction of anesthesia, but before the start of surgery and approximately every 30 minutes thereafter till end of surgery. <br/ ><br>Intraoperatively at any time point if the non-invasive Hb value reaches the trigger point for blood transfusion i.e 9 gm%, arterial blood sample will be collected for Hb estimation using arterial blood gas (ABG) machine (aHb). <br/ ><br> <br/ ><br>
- Secondary Outcome Measures
Name Time Method 2.We will also assess the cerebral oxygenation at the above time point using near infrared spectroscopy [NIRS]Timepoint: Intraoperatively at any time point if the non-invasive Hb value reaches the trigger point for blood transfusion i.e 9 gm%, arterial blood sample will be collected for Hb estimation using arterial blood gas (ABG) machine (aHb). Simultaneously, the cerebral oxygenation value will be recorded at same time point.
