Clinical Study Of Multimodal Analgesia For Acute Pain After Thoracotomy

Objective(s):Thoracic surgery has always been the basis of thoracic surgery.Thoracic surgery has caused more trauma and damage to tissues and nerves.As a result,postoperative pain is difficult to control and may even develop into a chronic open chest postoperative pain syndrome.The patient's postoperative quality of life can even lead to unbearable pain and psychological depression.This topic discusses the effect of ropivacaine intercostal nerve block combined with PCIA analgesia on postoperative pain relief in patients undergoing thoracotomy.Methods:Analysis of 30 patients undergoing elective thoracotomy from January 2017 to September 2017 in Yunnan Provincial Tumor Hospital,18 males and 12 females were randomly divided into INB+PCIA group(experimental group)and PCIA group(control group).At the end of the procedure,the surgeons performed an intercostal block of 0.75%ropivacaine(15ml)in the INB + PCIA group.The range consisted of the upper and lower intercostal space and drainage tube incisions.All patients underwent PCIA for analgesia.PCIA drugs were:sufentanil 150mg and butorphanol 6mg added to 0.9%normal saline 100ml.VAS scores were recorded at rest on the first day(T1),two days(T2),five days(T3),and seven days(T4)of the postoperative day when the test group and the control group were resting;and the dose of abucillin hydrochloride used before discharge was recorded.Record postoperative complications before discharge.Results:The VAS score at rest at the T1 and T2 time points in the experimental group was lower than that in the control group(P=0.037,P=0.030).The cumulative amount of pain medication before discharge and the postoperative complication rate in the experimental group were lower than those in the control group(P).=0.031,P=0.019);There was no statistically significant difference in VAS score between the test group and the control group at T3 and T4 time points(P=0.068,P=0.019).Conclusion(s):The ropivacaine intercostal nerve block combined with analgesia pump for analgesia after thoracotomy can reduce the pain within 48 hours and reduce postoperative respiratory complications.
