Analgesic Effect Of Erector Spinae Muscle Block After Posterior Lumbar Spine Surgery

Objective: Compare the preoperative erector spinae plane block(ESPB)combined total intravenous anesthesia(TIVA),preoperative incision infiltration(IF)combined total intravenous anesthesia(TIVA)compared Comparison of analgesic effect of intravenous anesthesia(TIVA)on posterior lumbar spine surgery.Methods: A total of 240 patients who underwent posterior lumbar spine surgery from January to December 2019 were selected.TIVA group(full intravenous anesthesia,n=80),ESPB group(ESPB combined TIVA,n=80)and IF group(IF combined TIVA,n=80).Record the patient’s basic information,anesthetic drug consumption,anesthesia time,Numeric Rating Scale(NRS)at postoperative rest,Patient controlled intratravenous analgesia(PICA)hydromorphone hydrochloride Consumption,postoperative complications and adverse reactions,operator and patient satisfaction,bed time,etc.Analyze and compare the differences between the three groups.Results: There were no significant differences in the basic information,anesthesia time,intraoperative fluid replacement volume,and incision length among the three groups of patients(P> 0.05).Among the three groups,the consumption of anesthesia drugs in the TIVA group was the highest in the four groups,and the ESPB group was the lowest.Postoperative NRS showed that,except for the 48-hour NRS group,the NRS values of the other groups were highest in the TIVA group and lowest in the ESPB group.The consumption of hydromorphone hydrochloride in the three groups was highest in the TIVA group and lowest in ESPB.The TIVA group had the most analgesia pump compressions,and the ESPB group had the least compressions.By analyzing the need for remedial analgesia,and whether postoperative adverse reactions and complications were found in the three groups,the number of postoperative adverse reactions and complications was highest in the TIVA group and the lowest in the ESPB group.It was found that the satisfaction of the three groups of surgeons,patients,and bed time were lower in the TIVA group and higher in the ESPB group.Conclusion: Compared with TIVA alone,IF and ESPB can reduce the consumption of opioids,provide better postoperative analgesia,and reduce adverse reactions,but ESPB performs better.
