The Clinical Study Of Ultrasound-Guided Single Erector Spinae Plane Block On Patients Undergoing Video-assisted Thoracoscopic Lobectomy

ObjectiveThe present study was designed to investigate the effects of postoperative analgesia of erector spinae plane(ESPB)in patients undergoing video-assisted thoracoscopic lobectomy.MethodsSixty parturients(age 35-75 years,weight 55-85 kilo,ASA ?or ?),scheduled for elective thoracoscopic lobectomy under spinal anaesthesia were randomly allocated into two groups(n=30).Group E:ESPB was performed before the anesthesia(0.5%ropivacaine 30 mL),and group I:INB was performed before the anesthesia.The scores of visual analogue scale(VAS)were VAS recorded at postoperative 1,6,12,24 and 48 h,the pump-press number,additional analgesics cases,side effects and complications were also recorded.ResultsThere were no significant differences in the age,sex,weight,ASA grade,and operation time between the two groups(P>0.05).The operation time of nerve block in group E and group I was(4.39±0.82)min and(5.77±0.95)min,respectively.Compared with group E,the operation time of intercostal nerve block in group I was significantly prolonged(P<0.001).Compared with group I,the VAS scores at rest and activity were significantly lower in group E at 1,6,12,and 24 h after operation(P<0.05).The effective compression times of PCIA pump in group E and group I were 6.8413.25 times/person and 8.7612.79 times/person.Compared with group I,the number of effective compressions of PCIA pump in group E was significantly reduced(P=0.0171<0.05).There was no need for additional remedial analgesics in the two groups within 48 hours after surgery.The incidence of postoperative nausea was 3.3%and 26.7%in group E and group I,respectively.The incidence of postoperative nausea was significantly lower in group E(P=0.013<0.05).No vomiting occurred in either group.There was no skin itching in group E,and the incidence of skin itching in group I was 6.7%.There was no significant difference between the two groups(P=0.246>0.05).There were no complications such as pneumothorax,local anesthetic poisoning,visceral injury and total spinal anesthesia in both groups.ConclusionUltrasound-guided ESP was superior to INB when it comes to postoperative analgesia in patients undergoing video-assisted thoracoscopic lobectomy.The VAS score and consumptions of opioids were decreases,and postoperative nausea and vomiting were reduced.
