BACKGROUND: Propofol has been widely used in bidirectional gastrointestinal endoscopy sedation; however, it frequently leads to cardiovascular adverse events and respiratory depression. Propofol target-controlled infusion (TCI) can provide safe sedation but may require higher dosages of propofol. On the contrary, etomidate offers hemodynamic stability.
AIM: To evaluate the effect of different dose etomidate added to propofol TCI sedation during same-visit bidirectional endoscopy.
METHODS: A total of 330 patients from Fujian Provincial Hospital were randomly divided into three groups: P, 0.1EP, and 0.15EP. Patients in the P group received propofol TCI only, with an initial effect-site concentration of the propofol TCI system of 3.0 mg/mL. Patients in the 0.1EP and 0.15EP groups received 0.1 and 0.15 mg/kg etomidate intravenous injection, respectively, followed by propofol TCI.
RESULTS: Patients in the 0.15EP group had higher mean blood pressure after induction than the other groups (P group: 78 mmHg, 0.1EP group: 82 mmHg, 0.15EP group: 88 mmHg; P < 0.05). Total doses of propofol consumption significantly decreased in the 0.15EP group compared with that in the other groups (P group: 260.6 mg, 0.1EP group: 228.1 mg, 0.15EP group: 201.2 mg; P < 0.05). The induction time was longer in the P group than in the other groups (P group: 1.9 ± 0.7 minutes, 0.1EP group: 1.2 ± 0.4 minutes, 0.15EP group: 1.1 ± 0.3 minutes; P < 0.01). The recovery time was shorter in the 0.15EP group than in the other groups (P group: 4.8 ± 2.1 minutes, 0.1EP group: 4.5 ± 1.6 minutes, 0.15EP group: 3.9 ± 1.4 minutes; P < 0.01). The incidence of hypotension (P group: 36.4%, 0.1EP group: 29.1%, 0.15EP group: 11.8%; P < 0.01) and injection pain was lower in the 0.15EP group than in the other groups (P < 0.05). Furthermore, the incidence of respiratory depression was lower in the 0.15EP group than in the P group (P < 0.05). Additionally, the satisfaction of the patient, endoscopist, and anesthesiologist was higher in the 0.15EP group than in the other groups (P < 0.05).
CONCLUSION: Our findings suggest that 0.15 mg/kg etomidate plus propofol TCI can significantly reduce propofol consumption, which is followed by fewer cardiovascular adverse events and respiratory depression, along with higher patient, endoscopist, and anesthesiologist satisfaction.
