Discussion on the Analgesic Effect of Ultrasound-guided Adductor-Canalblockade in Tibial Fracture
Objective To explore the effect of ultrasound-guided adductor-canalblockade in postoperative analgesia of tibial fracture patients.Methods A total of 110 patients with tibial fracture admitted to Liuhe District People's Hos-pital of Nanjing from March 2020 to December 2022 were conveniently selected as the research objects.According to different anesthesia schemes,they were divided into control group(n=55,routine patient-controlled analgesia)and ob-servation group(n=55,ultrasound-guided adductor-canalblockade).The degree of postoperative pain,the use of post-operative analgesic drugs and adverse reactions were compared between the two groups.Results The resting pain scores of the observation group at 4 h,8 h,12 h,24 h and 48 h after operation were(3.24±1.24)points,(2.97±1.04)points,(2.80±1.02)points,(2.48±0.84)points and(2.27±0.76)points,respectively,which were lower than those of the control group(3.95±1.47)points,(3.74±1.22)points,(3.57±1.17)points,(3.24±1.06)points and(2.95±0.94)points,the differences were statistically significant(t=2.738,3.562,3.679,4.167,4.172,all P<0.05).The knee pain score of the observation group were lower than those of the control group at each time point,and the differences were statisti-cally significant(all P<0.05).The dosage of tramadol in the observation group was less than that in the control group,and the incidence of adverse reaction was lower than that in the control group,the differences were statistically signifi-cant(both P<0.05).Conclusion The application of ultrasound-guided adductor-canalblockade in postoperative anal-gesia of patients with tibial fracture can reduce postoperative pain and reduce the dosage of anesthetic drugs,with fewer adverse reactions.
