The relationship between perfusion index and postanesthetic shivering has been investigated in limited studies. Previous studies have investigated the relationship between postanesthetic shivering after total intravenous anesthesia and perfusion index. The relationship between inhalational anesthesia and postoperative shivering has been investigated, but the role of perfusion index on shivering has also been evaluated in limited studies. Therefore, investigators aimed to investigate whether perianesthetic changes in perfusion index in patients under general anesthesia (inhalation anesthesia and total intravenous anesthesia) correlate with the incidence of postanesthetic shivering and whether they are useful in predicting postanesthetic shivering.
