The Ability of Perfusion Index and Positional Perfusion Index Variation to Predict Spinal Anesthesia-induced Hypotension in Elderly Patients

The Ability of Perfusion Index and Positional Perfusion Index Variation to Predict Spinal Anesthesia-induced Hypotension in Elderly Patients: A Prospective Observational Study

In this study, we will test the ability of positional perfusion index variation to predict post-spinal anesthesia hypotension in elderly patients.

Inclusion Criteria:

• 65 years of age or more.
• ASA score I & II.
• Patients scheduled for surgeries under spinal anesthesia.

Exclusion Criteria:

• Negative consent.
• pre-existing hypertension
• Diabetes mellitus or autonomic neuropathy.
• Emergency operations.
• Absolute contraindications or failure to perform spinal anesthesia.
