5-minute perfusion index change
ability of perfusion index change 5 minutes after induction in predicting propofol sedation-induced hypotension (perfusion index change is calculated as the percent change from baseline values)
Time frame: After sedation until start of surgery (an average of 20 minutes)
10-minute perfusion index change
ability of perfusion index change 10 minutes after induction in predicting propofol sedation-induced hypotension (perfusion index change is calculated as the percent change from baseline values)
Time frame: After sedation until start of surgery (an average of 20 minutes)
baseline perfusion index
ability of baseline perfusion index in predicting propofol sedation-induced hypotension
Time frame: After sedation until start of surgery (an average of 20 minutes)
5-minute perfusion index
ability of perfusion index 5 minutes after induction in predicting propofol sedation-induced hypotension
Time frame: After sedation until start of surgery (an average of 20 minutes)
10-minute perfusion index
ability of perfusion index 10 minutes after induction in predicting propofol sedation-induced hypotension
Time frame: After sedation until start of surgery (an average of 20 minutes)
5-minute perfusion index change difference
difference of perfusion index change 5 minutes after induction between participants who do or do not develop hypotension during propofol sedation after spinal anesthesia (perfusion index change is calculated as the percent change from baseline values)
Time frame: After sedation until start of surgery (an average of 20 minutes)
