Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Both in two groups that under go major surgery, Hb follow-up will be performed with arterial blood gas sampling which is already performed in routine procedure. In the SpHb group, Hb values obtained with continuous Hb analysis trend will be recorded till the end of surgery and also blood gas sample will be obtained in sudden falls in this trends.The amount of transfusion delivered during the postoperative intensive care unit, the Hb values at the intensive care unit and the complications during the intensive care unit will be recorded.Patients in both groups will be monitored with the M-LNCS probe, which only measures the PVI connected to the Radical-7 Pulse CO-Oximeter.In patients with SpHb group, additional SpHb values will be monitored with 2414 Hb probe (Masimo, Irvine, CA) connected to Radical-7 Pulse CO-Oximeter device.

Summary
Brief summary
Our primary aim in this prospective and observational study was to determine the effect of spHb monitor on perioperative blood transfusion in patients undergoing major surgery.In this study, our hypothesis is that this measurement method called SpHb, which is called continuous SpHb during major surgery, will reduce the amount of transfusion and lead to less metabolic and hemodynamic instability compared to the management based on Hb measurement by intermittent blood sampling
