Effects of ultrasound-guided stellate ganglion block(SGB)on cardiac function and gastrointestinal function in elderly patients undergoing colorectal cancer surgery
Objective To analyze the effect of ultrasound-guided stellate ganglion block(SGB)in elderly patients undergoing surgical treatment for colorectal cancer.Methods The clinical data of 80 elderly pa-tients with frailty who underwent colorectal cancer surgery in the hospital from January 2022 to November 2023 were retrospectively analyzed.According to the intraoperative anesthesia method,thepatients were divided into a control group(41 cases)and an observation group(39 cases).The control group was given general anesthesia combined with epidural anesthesia,and the observation group was added ultrasound-guided SGB on the basis of the control group.The perioperative related indicators,visual analogue scale(VAS)score,stress index,cardiac function index level at different time points of T0(before anesthesia in-duction),T1(5 min after anesthesia),T2(at the end of operation),gastrointestinal function and adverse reactions were compared between the 2 groups.Results The consumption of sufentanil and propofol,pressing times of analgesic pump and rescue analgesia rate in the observation group were lower than those in the control group(P＜0.05).At 2 h,12 h and 24 h after theoperation,the VAS scores of the 2 groups gradually weredecreased,and the VAS score of the observation group was lower than that of the control group(P＜0.05).After the operation,the levels of superoxide dismutase(SOD)and cortisol(Cor)in the 2 groups were higher than those before theoperation,but those in the observation group were lower than those inthe control group(P＜0.05).The levels of heart rate(HR),cardiac output(CO)and mean arterial pressure(MAP)at T1 and T2 in the 2 groups were higher than those at T0,and lower at T2 than those at T1,but the levels of HR,CO and MAP at T1 and T2 in the observation group were lower than those in the control group(P＜0.05).Compared with the control group,the recovery time of bowel sounds and the first exhaust time were shortened in the observation group(P＜0.05).Conclusion Ultra-sound-guided SGB for elderly frail patients with colorectal cancer can reduce the amount of intraoperative anesthetic drugs,effectively improve the analgesic effect,relieve stress reaction,and has little effect on cardiac function and gastrointestinal function,and it is safe and reliable.
