Introduction: This study investigates the application of bispectral index (BIS) monitoring in rigid bronchoscopy to enhance anesthetic delivery and patient outcomes, a topic that remains underexplored.
Materials and methods: A retrospective analysis of 155 patients undergoing elective rigid bronchoscopy under general anesthesia was conducted. Patients were divided into BIS-monitored and conventional anesthesia groups. Inclusion criteria were adults aged over 18 years with American Society of Anesthesiologists (ASA) physical status I-IV.
Result: No significant demographic differences were found between the groups. The BIS group showed significant reductions in propofol usage (231.40 ± 74.63 mg vs. 190.19 ± 91.83 mg, p= 0.003) and prednol dosage (94.27 ± 42.56 mg vs. 79.71 ± 18.97 mg, p= 0.020). Remifentanil administration approached statistical significance (56.99 ± 34.69 mcg vs. 45.36 ± 36.75 mcg, p= 0.055).
Conclusions: No significant demographic differences were found between the groups. The BIS group showed significant reductions in propofol usage (231.40 ± 74.63 mg vs. 190.19 ± 91.83 mg, p= 0.003) and prednol dosage (94.27 ± 42.56 mg vs. 79.71 ± 18.97 mg, p= 0.020).
