Anesthesiologist Workload

This prospective observational cohort study aims to investigate whether the weight-based equivalent (mg/kg) of a fixed 1 g dose of tranexamic acid administered during septorhinoplasty is associated with intraoperative remifentanil titration frequency and perceived anesthesiologist workload. Although tranexamic acid is routinely given as a fixed dose, its mg/kg equivalent varies according to patient weight and may influence hemodynamic management during controlled hypotension. The primary outcome is the total number of remifentanil infusion rate adjustments during surgery. Secondary outcomes include total remifentanil consumption and postoperative anesthesiologist workload assessed using the NASA Task Load Index (NASA-TLX).
