Clinical efficacy of multimodal analgesic pain control on the posterior lumbar spine surgery / 中国综合临床

ABSTRACT

Objective To evaluate the efficiency of multimodal analgesia for the patients who had the posterior lumbar spine surgery.Methods Sixty-four cases of patients who were scheduled to the posterior lumbar spine surgery were randomly divided into two groups, multimodal analgesia group (n =32) and control group(n=32).Multimodal analgesia group patients were given oxycodone acetaminophen 1 day before and the next day after operation, during the operation the patients received injiection of multimodal drugs (consisting of ropivacaine 150 mg, flurbiprofen 50 mg, phenylephrine 0.4 ml, normal saline 50 ml) around the incisions by infiltrated injection before the skin incision closed, then had controlled intravenous analgesia.In the control group, the incisions were sutured without the local infiltration analgesia.Then only had patient controlled intravenous analgesia after operati on.Visual analogue scale(VAS) ,Japanese Orthopedic Association(JOA) and Prolo lumbar function score was recorded respectively perioperatively.Results (1) VAS the patients of multimodal analgesia group had significantly lower rest pain scores and activity pain scores at 6, 12,24 hours, first moving than the control group((3.1±1.6) ,(2.8±1.1),(2.4±0.9) ,(2.3±1.1) vs.(3.5±1.8) ,(3.4± 1.3), (3.4±0.8), (3.0± 1.5), P＜0.05).There was no significant difference at the discharge between the two groups (P＞0.05).(2)JOAJOA scores of the patients of multimodal analgesia group were obviously higher than that of the control group at 1,3,7 days after operation (P＜0.05).There was no significant difference at the discharge between the two groups (P＞0.05).(3) Prolo lumbar function score Prolo scores of the patients of the multimodal analgesia group were obviously higher than that of control group at 1,3,7 days after operation (P ＜0.05).There was no significant difference at the discharge between the two groups(P＞0.05).Conclusion Multimodal Analgesia is shown to safely provide excellent pain control and functional recovery.It can reduce visual analogue pain score and improve lumbar function after surgery.
