Abstract

To investigate the efficacy of preemptive analgesia with tramadol injection after single-segment lumbar spinal stenosis surgery is the objective of the study. A total of 120 patients after lumbar spinal stenosis surgery were selected by the random sampling method as the study subjects. Patients were randomly divided into a moderate pain group (control group, n=60) and a preemptive analgesia group (observation group, n=60) according to whether tramadol preemptive analgesia was used. The visual analogue scale score of the two groups were compared at 30 min, 4 h, 8 h, 16 h, 24 h and 48 h after treatment, the number of intramuscular tramadol injections and the total dosage of tramadol administration from the end of surgery to discharge, as well as adverse reactions after treatment. The visual analogue scale score at 30 min, 4 h, 8 h, 16 h and 24 h after surgery of the observation group were significantly lower than the control group (p<0.05). There was no significant difference between the two groups in the visual analogue scale score at 48 h after surgery (p>0.05).The number of intramuscular tramadol injections and the total dosage of tramadol administration from the end of surgery to discharge of the observation group were significantly lower than the control group (p<0.05). The incidence of adverse reactions in the observation group was lower than the control group, but the difference was not statistically significant (p>0.05). Tramadol preemptive analgesia after lumbar spinal stenosis surgery could effectively control pain, reduce the use frequency of postoperative painkillers, reduce the dosage of intramuscular tramadol after surgery and had fewer adverse reactions in the process of treatment to some extent.
