Effects Of Ultrasound-guided Erector Spinae Plane Block For Postoperative Pain And Recovery In Laparoscopic Radical Operation Of Colon Cancer

Objective: To investigate the effect of ultrasound-guided Erector Spinae Plane Block(ESPB)combined with patient-controlled intravenous analgesia on postoperative analgesia and recovery in patients undergoing laparoscopic radical operation of colon cancerMethods: 64 patients,scheduled for electively laparoscopic laparoscopic radical operation of colon cancer were divided into controlled group(group C)and ESPB group(group E)using a random number table method,with 34 patients in each group.Patients in group C were given intravenous anesthesia,and patients in group E were given ultrasoundguided bilateral erector spinae plane block at T7 level followed by intravenous anesthesia.Patients in both groups were given patient-controlled intravenous analgesia(PCIA)at the end of the surgery.Record the number of times hemodynamic instability during surgery(the mean intraoperative arterial pressure fluctuation amplitude exceeding 20% of the baseline value for more than 1 minute was considered as hemodynamic instability)was recorded in both groups;The operation time and extubation time(the time from the end of operation to the extubation of tracheal tube)were recorded.The cumulative consumption of sufentanil in the surgery and 24 hours after surgery were recorded.Visual Analogue Scale(VAS)scores in resting and moving period at 2h,4h,8h,12 h and 24 h after surgery were recorded.Record the time between the end of the operation and the first postoperative pressure on the analgesia pump(hereinafter referred to as the time of the first compression of analgesic pump)and the total times of the compression of the analgesic pump within 24 hours after the surgery.Record the time from the end of surgery to the patient's first exhaust(hereinafter referred to as the first time of exhaust),and the time from the end of surgery to the patient's first getting up(hereinafter referred to as the first time of getting up)Postoperative complications such as nausea and vomiting,irritability and respiratory depression were recorded.Result: The number of hemodynamic instability in group E was significantly less than that in group C(P<0.05).There was no significant difference in the operation time between the two groups(P>0.05),and the extubation time of group E was earlier than that of group C(P<0.05).Compared with group C,the cumulative consumption of sufentanil in the surgery and 24 hours after surgery of group E decreased significantly(P<0.05).VAS scores in resting and moving period at 2h,4h,8h,12 h and 24 h after surgery in group E were significantly lower than those in group C(P<0.05).The time of the first compression of analgesic pump in group E was significantly later than that in group C.Compared with group C,the total times of the compression of the analgesic pump within 24 h after the surgery in group P were significantly reduced.The first time of exhaust and getting up after the surgery in group E were significantly earlier than those in group C,and the length of hospital stay after operation in group E was significantly shorter than that in group C(P<0.05).Compared with group C,the incidence of postoperative complications such as nausea and vomiting,irritability and respiratory depression in group E was significantly lower(P<0.05).There was no block-related complications were found in group E.Conclusion: Ultrasound-guided erector spinae plane block can provide effective postoperative analgesia for patients undergoing laparoscopic radical operation of colon cancer,and significantly reduce the consumption of opioids during and after the operation,and make the hemodynamics more stable during the operation.In addition,it can also reduce the incidence of adverse reactions after laparoscopic radical operation of colon cancer,promote the early postoperative recovery of patients,and shorten the length of hospitalization.
