Objectives
Narrative objectives1
In this study, the ability to predict fluid responsiveness of the change in the peripheral perfusion index (PI) in response to 0.1 mg of phenylephrine is investigated. Fluid responder is determined by SVV >12%.

Results
42 patients were included in this study. The stroke volume (SV) in patients with preload dependency (n=23) increased after phenylephrine administration. However, phenylephrine administration did not impact the SV in patients without preload dependency (n=19). The perfusion index (PI) decreased regardless of preload dependency. The changes in the PI after phenylephrine administration exhibited low accuracy for predicting preload dependency.

Baseline Characteristics
Patients older than 18 years who were scheduled for surgery and who underwent radial artery catheter placement and cardiac output monitoring between January and April 2023 were included in this study. Exclusion criteria were severe preoperative lung disease (Chronic Obstructive Pulmonary Disease clinical stage of Global Initiative for Chronic Obstructive Lung Disease 3 or 4 or a history of lung resection), left ventricular ejection fraction of less than 40%, atrial fibrillation, right heart failure (suspected pulmonary hypertension or elevated central venous pressure), obesity (body mass index above 35 kg/m2), emaciation (body mass index less than 15 kg/m2), peripheral artery disease, haemodialysis, hyperthyroidism, bradycardia (HR less than 50 bpm/min), and brachial plexus block administration
Participant flow
This was a non-invasive observational study and prior written consent was not required by the Ethics Committee. Patients were included in the study if they had a mean arterial pressure of 65 mmHg after induction of general anesthesia and before the start of surgery.
Adverse events
none
Outcome measures
Does the rate of change in PI (1 and 2 minutes after administration) predict preload dependence (SVV above 12%) after administration of 0.1 mg of phenylephrine when mean blood pressure is less than 65 mmHg?

Other related information
Between tracheal intubation and skin incision, if the mean arterial pressure falls below 65 mmHg, the BIS value, systolic pressure, mean arterial pressure, diastolic pressure, heart rate, CI, SV, SVV, PPV, stroke volume, PI and PVI are recorded, and 0.1 mg phenylephrine is administered. Record the values 1 and 2 minutes after administration, respectively. During this 2-minute period, any changes in position, anaesthetic depth or other administration of vasoactive drugs should not be allowed.
