Safety and tolerability outcomes of nonanesthesiologist-administered propofol using target-controlled infusion in routine GI endoscopy.

Background and Aims: Nonanesthesiologist-administered propofol (NAAP) is increasingly accepted, but data are limited on drug administration using target-controlled infusion (TCI) in clinical practice. TCI adjusts the drug infusion based on patient-specific parameters, maintaining a constant drug dose to reduce the risk of adverse events (AEs) because of drug overdosing and to enhance patient comfort. The aims of this study were to assess the rate of AEs and to evaluate patient satisfaction with NAAP using TCI in a retrospective cohort of 18,302 procedures.
Methods: Low-risk patients (American Society of Anesthesiologists score I and II) undergoing outpatient GI endoscopic procedures, including EGDs and colonoscopies, were sequentially enrolled at IRCCS San Raffaele Hospital (Milan, Italy) between May 2019 and November 2021.
Results: Data from 7162 EGDs and 11,140 colonoscopies were analyzed. Mean patient age was 59.1 ± 14.8 years, and mean body mass index was 24.9 ± 3.7 kg/m ² . The male-to-female ratio was equal at 8798 (48.1%):9486 (51.9%). AEs occurred in 240 procedures (1.3%) out of the total cohort, with no differences between EGDs and colonoscopies (100 [1.4%] and 140 [1.2%], respectively; P = .418). Most patients (15,875 [98.9%]) indicated they would likely repeat the procedure with the same sedation protocol. Age (odds ratio, 1.02; 95% confidence interval, 1.01-1.03; P < .008) was the only independent factor associated with overall AEs.
Conclusions: NAAP using TCI is an effective and safe sedation method for routine endoscopy. The proper propofol dosage based on individual patients and the presence of trained operators are crucial for NAAP sedation management.
