ABSTRACT

ObjectiveTo evaluate the clinical effects of early pain intervention provided by an acute pain service team on the efficacy of postoperative patient-controlled analgesia ( PCA).MethodsOne thousand four hundred and sixty-seven patients receiving postoperative PCA in November and December 2011 were enrolled in this study.Patients were excluded from the study if they were ＜ 12 yr,unconscious or uncoorperative.The patients were divided into control group (group C,n =725) and intervention group (group 1,n =742).Group 1 received preoperative systematic pain education on the significance and conect use of PCA including pharmacology of analgesic (sufentanil 100 μg in normal saline 100 ml) by an acute pain service team made up of anesthesiologists and nurses specializing in pain management.The education was repeated immediately before operation and when the patients were discharged from recovery room.While in grup C the correct use of PCA was explained routinely before operation by anesthesiologists and nurses taking care of the patients.The incidence of incomplete analgesia and adverse reactions and patient' s satisfaction were rated.ResultsThe incidence of incomplete analgesia was significantly lower and the patient's satisfaction higher in group 1 than in control group.There was no significant difference in adverse reactions between the two groups.ConclusionEarly pain intervention provided by an acute pain service team is effective in improving the efficacy of postoperative PCA and patient's satisfaction.
