RESUMO
Objective To evaluate the effect of the acupressure wristbands combined with tro-pisetron on the effect in preventing postoperative nausea and vomiting (PONV)and the quality of re-covery during early period after radical mastectomy.Methods Seventy-five patients,aged 35-68 years,ASA physical status Ⅰ or Ⅱ,scheduled for elective radical mastectomy,were randomly as-signed into three groups (n=25):acupressure wristband group (group A),tropisetron group (group B)and acupressure wristbands combined with tropisetron group (group C).At 30 min before the sur-gery,the acupuncture pins were placed on Nei Guan point till 24 h after the surgery in group A.At 30 min before the end of the surgery,tropisetron 6 mg was intravenously injected in group B.At 30 min before the surgery,the acupuncture pins were placed on Nei Guan point till 24 h after the surgery;at 30 min before the end of the surgery,tropisetron 6 mg was intravenousy injected in group C.The three groups received total intravenous anesthesia.The occurrence of nausea and vomiting was recor-ded immediately after extubation,6 h after surgery and 6-24 h after surgery.The global QoR-40 ag-gregate scores were recorded between the three groups on the day before surgery and 1 day after sur-gery.Results Compared with groups A and B,the incidence of PONV was significantly decreased in group C between the time immediately after extubation-6 h after surgery (P<0.05);and the severity of PONV was significantly decreased in group C (P<0.05 ).Compared with groups A and B, patients in group C produced higher physical comfort scores,emotional state scores,and pain scores (P<0.05 or P<0.01);the global QoR-40 scores of group C were significantly increased on 1 day after surgery (P<0.01).Conclusion The acupressure wristbands combined with tropisetron can re-duce the incidence and the severity of PONV,improve the quality of recovery during the early period after radical mastectomy.
