Objective To observe the therapeutic effect of otopoint-pellet pressure(OPP) combined with patient controlled intravenous analgesia(PCIA) for lower-limb surgery of orthopedics.Methods A total of 120 lower-limb orthopedic operation patients were randomized into OPP+PCIA group(n=60) and PCIA group(n=60).The patient's pain degree was evaluated by visual analogue score(VAS).Results In comparison with the simple PCIA group
VAS levels were significantly lower in the OPP+PCIA group than in the PCIA group 2
6
24 and 48 h after operation.The number of patients with post-operative reactions of nausea
vomiting and urinary retention in the OPP+PCIA group was remarkably lower than that of OPP group(P<0.05).Conclusion OPP+PCIA is superior to simple PCIA in post-operative analgesia and reducing post-operative adverse reactions in lower-limb orthopedic operation patients.
