The effect of low-dose ropivacaine combined with sufentanil on the onset time of anesthesia and postoperative rectal traction reflectance in patients undergoing mixed hemorrhoid surgery / 中国医师杂志

ABSTRACT

Objective:To investigate the effects of low-dose ropivacaine combined with sufentanil on the onset time of anesthesia and postoperative rectal traction reflectance in patients undergoing mixed hemorrhoid surgery.Methods:A total of 96 patients who underwent mixed hemorrhoid surgery at the General Hospital of the Southern Theater Command of the Chinese People′s Liberation Army from January 2020 to June 2021 were selected. They were randomly divided into a control group and an observation group using a random number table method, with 48 cases in each group. The control group was anesthetized with low-dose ropivacaine; The observation group was anesthetized with low-dose ropivacaine combined with sufentanil. The anesthesia effect, hemodynamic changes, pain score, bleeding score, postoperative rectal traction reflectance, and incidence of adverse reactions were compared between two groups of patients.Results:Compared with the control group, the observation group had a shorter onset time of anesthesia ( P<0.05) and a longer duration of anesthesia maintenance ( P<0.05). Before surgery, there was no statistically significant difference in heart rate and mean arterial pressure between the two groups of mixed hemorrhoid patients (all P>0.05); After surgery, both groups of patients had an increase in heart rate, a decrease in mean arterial pressure, and a more significant change in the control group (all P<0.05). Before surgery, there was no statistically significant difference in Visual Analogue Scale (VAS) scores and bleeding scores between the two groups of mixed hemorrhoid surgery patients (all P>0.05); After 1 day of surgery, the VAS score and bleeding score of both groups of patients were significantly reduced (all P<0.05), and the observation group showed a more significant decrease (all P<0.05). The postoperative recovery rate of anal contraction in the observation group was higher than that in the control group ( P<0.05), and the rectal traction reflectance was lower than that in the control group ( P<0.05). The total incidence of adverse reactions in the observation group was significantly lower than that in the control group (χ 2=4.667, P<0.05). Conclusions:The combination of low-dose ropivacaine and sufentanil has a definite anesthetic effect on patients undergoing mixed hemorrhoid surgery. It can improve the onset time of anesthesia and postoperative rectal traction reflectivity, alleviate patient pain, and has high safety.
