The Clinical Observation Of Postoperative Analgesia Effect Of Continuous Brachial Plexus Block Guided By Ultrasound And Neurostimulator In Children

Objective Ultrasound-guided Continuous brachial plexus block for postoperativeanalgesia is safe and effective,the adult has been used widely, However continuousbrachial plexus block guided by ultrasound and neurostimulator in children has not beenreported.We therefore investigate the effect and side effects of continuous brachialplexus block guided by Ultrasound and Neurostimulator in children.Methods40children aged2-7years undergoing elective surgery ofthe upper limb were randomly divided into two groups(n=20),the childrenand their families voluntary to use postoperative analgesia pump.continuous brachial plexus block in Group C,nurse controlled intravenousanalgesia in Group N,all the children were accept an brachial plexus blockunder general anesthesia with ultrasound-guided and neurostimulator,at theend of the surgery started analgesia. Group C receive an continuousinfusion with ropivacaine0.15%via the catheter for48h(basal rate,0.1ml/kg.h-1;bolus,0.05ml/kg; lockout30min),NCIA pump include sufentanil2ug/kg, tramadol5mg/kg, ondansetron2mg/kg,dexamethasone0.5mg/kg(basal rate,2ml/h;nurse-controlled bolus,0.5ml;lockout15min).then the motion pain score(FLACC score)was recorded at 2,6,12,18,24,36,48hours after surgery,as well as the amounts of patientwith a sensory block and motion block during the studied period,childrenhave sleep disruption at the night of postoperative0,adverse reactions andat the end of the study ask the families satisfaction.Results Compared with the N group, group C at6h,12h,18h pointFLACC score lower(p<0.05),there was no statistically significantdifference the rest of the time point.at2h and6h point,the percentages ofchildren with a sensory block in Group C is higher, at the rest study periodno patient presented sensory block.none of the patients in CBPB and NCIAgroups presented motor block.at the end of the study period,the parents ofchildren of Group C expressed a higher satisfaction mean score than GroupN(p<0.05).postoperative adverse reaction rate in Group C was significantlyreduced compared with Group there was no satistically significantdifference on the evening of the postoperative sleepdisruptions(p>0.05).Conclusions Continuous brachial plexus block guided by Ultrasonicand neurostimulator in children postoperative analgesia is a safe andeffective,and little influence on the body. significantly reduced nauseaand vomiting, urinary retention, skin itching and other side effects.
