Prediction of Hypotension Using Perfusion Index Following Spinal Anesthesia

NCT06427382 | Completed

• 1 other identifier: perfusion index
• Study Type: observational
• Target: 120
• Locations: 1 country
• Sites: 1

Brief Summary

It is aimed to investigate whether the perfusion index (PI) can predict hypotension after spinal anesthesia in elderly patients as much as in non-elderly patients.

Conditions

Anesthesia, Spinal

Keywords

spinal anesthesia; perfusion index; orthopedic surgery

Outcome Measures
