Brief summary

The aim was to investigate the effect of anesthesia management on perfusion index changes in obese patients and different anesthesia positions. The effect of positional intra-abdominal pressure and lung-related variables was investigated.

Detailed description

There may be changes in haemodynamic findings in patients after anaesthesia. The most common of these are hypotension and bradycardia. Many factors play a role on the hypotensive effect of anaesthesia induction1 . Position changes in patients during surgery in obese patients affect these changes.In our study, the changes in haemodimaic findings and the changes in PI and PVI were investigated in patients with BMI 30 and above and in patients with BMI within normal limits after induction of anaesthesia by giving prone position and sitting position.Position changes in patients during surgery in obese patients affect these changes. Hypertension and hypotension after induction of anaesthesia are common in obese patients. In addition, decreased venous return to the heart due to increased intrathoracic pressure during mechanical ventilation may trigger bradycardia and hypotension.
