Abstract:
Objective To observe the effect of midazolam plus propofol administered for colonoscopy on cognitive function in middle-aged and aged patients. Methods One hundred and thirty six patients, ASA I and II, aged 40~75 years and undergoing colonoscopy were randomized to propofol group (group P, n=68) and propofol plus midazolam group (group PM, n=68). Baseline cognitive function was measured using Mini mental state exami-nation (MMSE) before anesthesia and the cognitive testing was repeated 10 minutes after emerging from anesthesia. BP, HR, SpO2, analgesic effect and sedative drug doses in both groups were recorded. Procedure time, recovery time and Rasmay sedation score were both recorded. Results Recovery time was significantly longer in group PM than that in group P (P<0.05). The total dose of propofol was significantly smaller in group PM than that in group P (P<0.05). MMSE score of both groups decreased, but the incidence of cognitive decline and the level of cognition in group PM were more notable than those of group P (P<0.05). Conclusions Midazolam plus propofol and propo-fol alone administered for colonoscopy could both increase the incidence of cognitive decline, and the effect of the former is more notable, but midazolam added to propofol could reduce the dosage of propofol.
