Clinical Observation Of Multi-modal Analgesia After Arthroscopic Shoulder Surgery

[Objective]We designed one retrospective cohort study to compare interscalene block and intralesional block plus oral non-opioid medication after ASS.[Method]We divided total 151 subjects into 4 groups:group A(n=47)performed interscalene block after GA induction;Group P(n=33)performed interscalene block after wound closure;Group L(n=28)received intralesional block after wound closure.Group N(n=43)received nothing.All subjects received oral non-opioid medications routinely.The primary outcome was NRS in PACU.The secondary outcomes included longacting opioid consumption during both the procedure and during PACU;The ratio of total opioid consumption in floor during the first 24h operatively;Postoperative nausea and vomiting(PONV),emotional scale,oxygen supply,satisfaction of analgesia in floor during the first 24h.[Result]The ratio of NRS 0-3 in Group A and Group P were statistical high than Group L and Group N in PACU.The consumption of morphine was statistically low in Group A and Group P in PACU.The consumption of intraoperative morphine was lower in Group A.There was no statistical difference of the ratio of total opioid consumption in floor during the first 24h operatively,PONV,oxygen supply and satisfaction of analgesia in floor between 4 Groups.[Conclusion]Interscalene block performed superior analgesia in early period after ASS.Intralesional block did not presented advantage about decreased NRS and opioid consumption.Routine oral non-opioid medication was benefit for release the pain within first 24 hours.
