Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Intraoperative blood loss during rhinoplasty measured based on the total volume of blood collected in sterile gauzes and the suction reservoir. Timepoint: Intraoperatively, from the beginning of rhinoplasty to the end of surgery. Method of measurement: Intraoperative blood loss will be measured by calculating the total volume of blood collected in sterile surgical gauzes and the suction reservoir during surgery. | — |
Secondary
| Measure | Time frame |
|---|---|
| Systolic blood pressure measured during surgery. Timepoint: During surgery. Method of measurement: Systolic blood pressure will be measured using a noninvasive blood pressure monitoring device during surgery.;Diastolic blood pressure. Timepoint: During surgery. Method of measurement: Diastolic blood pressure will be measured using a noninvasive blood pressure monitoring device during surgery.;Mean arterial blood pressure. Timepoint: During surgery. Method of measurement: Mean arterial blood pressure will be measured using a noninvasive blood pressure monitoring device during surgery.;Heart rate. Timepoint: During surgery. Method of measurement: Heart rate will be measured using an electrocardiography monitoring device during surgery.;Postoperative pain intensity. Timepoint: In the recovery period after surgery. Method of measurement: Postoperative pain intensity will be measured using the Visual Analogue Scale.(VAS).;Postoperative analgesic consumption. Timepoint: During the postoperative period. Method of measurement: Total postoperative analgesic consumption will be recorded based on the amount of analgesic medications used during the postoperative period.;Surgeon satisfaction with surgical field. Timepoint: During surgery. Method of measurement: Surgeon satisfaction with the surgical field will be evaluated using a surgeon satisfaction assessment scale. | — |
