Abstract:
Objective To evaluate the anesthetic and postoperative analgesic effects of ultrasound-guided erector spinae plane block(ESPB)with dexmedetomidine combined with ropivacaine in percutaneous endoscopic lumbar discectomy(PELD).Method Patients underwent endoscopic discectomy were randomly divided into local infiltrative anesthesia group(group C),ropivacaine group(group R)and dexmedetomidine combined with ropivacaine group(group DR).Group C received local infiltration anesthesia with 0.375％ropivacaine 20 mL;in group R,the anesthesiologist used 0.375％ropivacaine 20 mL to perform bilateral ESPB.In DR group,0.375％ropivacaine+1 μg·kg-1 dexmedetomidine mixed solution 20 mL was used for bilateral ESPB.The changes of mean arterial pressure(MAP)and heart rate(HR)at 3 min before and after insertion of the channel were observed.The visual analogue scale(VAS)were recorded before operation(T0),at the time of needle positioning(T1),working channel placement(T2),annulus fibrosus operation(T3),at the end of operation(T4),at 4 h(T5),8 h(T6),12 h(T7)and 24 h(T8)after operation were observed.The dosage of intravenous analgesics,vasoactive drugs,and the occurrence of intraoperative adverse drug reactions were observed.Results There were 30 patients in group C,29 patients in group R and 30 patients in group DR.At 3 min after insertion into the channel,HR of group C,group R and group DR were(83.23±5.61),(78.18±4.71)and(77.31±5.13)beat·min-1;MAP were(85.97±3.89),(76.13±4.70)and(74.21±3.12)mmHg;with statistically significant difference(all P＜0.05).The VAS of group C,group R and group DR at T2were(5.80±0.85),(2.38±0.68)and(1.73±0.95)points;at T3 were(4.43±0.57),(2.55±0.57)and(1.63±0.56)points;at T7 were(4.66±0.66),(3.55±0.63)and(3.03±0.66)points;at T8 were(5.53±0.68),(4.07±0.46)and(3.23±0.57)points,all with significant difference(all P＜0.05).The number of additional cases of sufentanil in group C was 17 cases,and in group R was 5 cases,and in group DR was 3 cases,the number of additional cases of sufentanil in group R and DR was significantly less than that in group C(all P＜0.05).There was no significant difference in the incidence of adverse drug reactions among the three groups(all P＞0.05).Conclusion ESPB with dexmedetomidine combined with ropivacaine can significantly reduce intraoperative and postoperative pain,reduce intraoperative opioid use,and has no obvious adverse reactions in patients undergoing PELD.
