Investigation into the application of remimazolamin conjunction with low-dose propofolfor pediatricfiberoptic bronchoscopy

Abstract This study delves into the effectiveness of combining remimazolam with low-dose propofol in pediatric fiberoptic bronchoscopy. Ninety children scheduled for fiberoptic bronchoscopy in our hospital were enrolled as research participants. Based on the intraoperative anesthetic drug regimen, the children were divided into three groups: group R (remimazolam 0.2–0.4 mg/kg), group P (propofol 1–3 mg/kg), and group RP (remimazolam0.2 mg/kg, propofol 0.5 mg/kg). Immediately post-anesthesia, group P exhibited lower blood pressure and heart rate (HR) compared to both group R and group RP (P
