ABSTRACT
Objective:To evaluate the safety of naborphine hydrochloride combined with propofol in painless colonoscopy diagnosis and treatment of hypertensive patients.Methods:From October 2018 to September 2020, 900 patients with ASA grade Ⅰ to Ⅲ, aged 18 to 65, who underwent colonoscopy in Zhuhai Hospital Affiliated to Jinan University and Shanghai East Hospital Affiliated to Tongji University were prospectively selected. According to the random number table method, the patients were divided into 3 groups ( n=300): naborphine hydrochloride group 1 (N1 group, intravenous injection of 0.05 mg/kg naborphine hydrochloride); naborphine hydrochloride group 2 (N2 group, intravenous injection of 0.1 mg/kg naborphine hydrochloride); sufentanil group (SF group, intravenous injection of 0.1 μg/kg sufentanil). During anesthesia induction, propofol was combined with sedation, and the dose of propofol was 1.5 mg/kg. The systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), pulse oxygen saturation (SpO 2), respiratory rate (RR), and mean arterial pressure (MAP) of the three groups were compared before anesthesia (T 0), during induction (T 1), 1 min after induction (T 2), 2 min after induction (T 3), 3 min after induction (T 4) and 4 min after induction (T 5), and the bispectral index (BIS) were monitored. At the same time, the examination time, total dosage of propofol, recovery time, postoperative Visual Analogue Scale (VAS) score and perioperative anesthesia related adverse reactions of the three groups were compared. Results:There was no significant difference among the three groups in examination time, total dosage of propofol, recovery time, postoperative VAS score and adverse anesthetic reactions (all P>0.05). There was no significant difference in HR, SpO 2 and RR among the three groups at different time points (all P>0.05). The SBP, DBP and MAP in N1 group at T 1, T 3, T 4 and T 5 were lower than those in SF group (all P<0.05); The SBP, DBP and MAP in N2 group at T 1, T 3 and T 4 were higher than those in N1 group (all P<0.05). The BIS in T 3 and T 4 of N2 group was higher than that of N1 group (all P<0.05). Conclusions:0.1 mg/kg naborphine hydrochloride combined with propofol for painless enteroscopy in patients with hypertension has fine anesthetic effect and safety.
