PURPOSE: Propofol can be used alone or in combination with opioids during gastroscopy. This study aimed to assess the efficacy and safety of intravenous propofol and different doses of alfentanil in patients undergoing gastroscopy.
METHODS: A total of 300 patients undergoing sedative gastroscopy were randomly divided into four groups, and 0.9% saline (group A), 2 μg/kg alfentanil (group B), 3 μg/kg alfentanil (group C) or 4 μg/kg alfentanil (group D) were injected intravenously 1 min before the intravenous injection of 1.5 mg/kg propofol. If body movement and coughing occurred during the procedure, 0.5 mg/kg propofol would be administered intravenously. The primary outcome (awakening time) and secondary outcomes were recorded and analyzed, including hemodynamic changes, the incidences of body movement, coughing, hypoxemia, hypotension, hypertension, bradycardia, tachycardia, nausea and vomiting, drowsiness and dizziness.
RESULTS: Patients in group C (7.0 [5.0 to 8.0] min) and group D (6.0 [5.0 to 7.0] min) woke up significantly earlier than those in group A (8.0 [6.0 to 10.0] min) (P < 0.001). Patients in group A experienced more body movement (P = 0.001) and coughing (P < 0.001) than the other groups. With the increasing dose of alfentanil, the morbidity of hypotension and bradycardia increased significantly (P = 0.001), while the incidence of dizziness decreased significantly (P = 0.037). The incidences of hypoxemia, tachycardia, drowsiness, nausea and vomiting were similar among the four groups (P > 0.05).
CONCLUSIONS: Intravenous 1.5 mg/kg propofol combined with 3 μg/kg alfentanil is more suitable for patients undergoing gastroscopy, and the dose of alfentanil can be reduced according to the patient's actual physical condition.
