Design outcomes

Primary

Measure	Time frame
The primary objective of the study is to compare the measurement of haemoglobin concentration with arterial blood gas analyser to conventional laboratory methods during induction of anaesthesia among major head and neck surgeries.Timepoint: before induction	—

Secondary

Measure	Time frame
Secondary objectives include comparing haemoglobin values from arterial blood gas analyser to conventional laboratory method during 10% of maximum allowable blood loss and effect of haemodilution in the immediate postoperative period in haemoglobin values.Timepoint: at 10% blood loss, end of surgery	—
