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.

ABSTRACT

Objective:To investigate the effects of thoracic paravertebral nerve block combined with propofol intravenous anesthesia (PPA) on hemodynamic parameters, inflammatory stress indexes, postoperative analgesia and immune indexes in patients with lung cancer undergoing radical surgery.Methods:116 patients with lung cancer admitted to the Southern Theater General Hospital from January 2020 to December 2021 were randomly divided into observation group and control group, with 58 patients in each group. The observation group received PPA combined with general anesthesia, and the control group received sevoflurane inhalation combined with general anesthesia; the hemodynamic parameters, the amount of anesthetic and analgesic drugs used during and after the operation, the pain score of the patients after the operation, the serum interleukin-6 (IL-6), interleukin-10 (IL-10), cortisol (Cor), norepinephrine (NE), vascular cell growth factor-C (VEGF-C), transforming growth factor-β 1(TGF-β1) and T lymphocytes before and after the operation, adverse reactions of the two groups were monitored and compared.Results:The intraoperative dosage of remifentanil and postoperative dosage of sufentanil in the observation group were lower than those in the control group (all P<0.05). There was no statistically significant difference in cardiac output (CO), systemic vascular resistance index (SVRI) and extravascular lung water index (EVLWI) between the observation group and the control group at T 0 to T 3 (all P>0.05); The mean arterial pressure (MAP) at T 1 to T 2 in the observation group was higher than that in the control group, and the MAP at T 3 was lower than that in the control group (all P<0.05). There was no significant difference between observation group and control group in Visual Analogue Scale (VAS) scores at resting state and coughing state 2 h after surgery(all P>0.05). The VAS scores in the observation group at resting state were lower than those in the control group at 4 h and 12 h after surgery (all P<0.05), and the VAS scores in the observation group at coughing state were lower than those in the control group at 4 h, 12 h and 24 h after surgery (all P<0.05). Before surgery, there was no significant difference in serum levels of IL-6, IL-10, Cor, NE, VEGF-C and TGF-β1 between observation group and control group (all P>0.05). The serum levels of IL-6, NE and VEGF-C in observation group were lower than those in control group 24 h after surgery (all P<0.05). Before surgery, there was no significant difference in CD3 +, CD4 + and CD8 + between observation group and control group (all P>0.05). 24 h after operation, the CD3 + in observation group was higher than that in control group ( P<0.05). The incidence of adverse reactions in observation group (10.34%) was lower than that in control group (24.14%, P<0.05). Conclusions:PPA anesthesia for patients undergoing radical resection of lung cancer is conducive to maintaining the stability of hemodynamic parameters, reducing the inflammatory stress response of patients, the impact of surgery on patients′ immune function, and the amount of anesthetic drugs and postoperative analgesics during surgery.
