Clinical effect of the combined medication to prevent postoperative adjuvant chemotherapy-related nausea and vomiting / 中国综合临床

ABSTRACT

Objective To observe the clinical effect of the combined medication to prevent postoperative adjuvant chemotherapy-related nausea and vomiting after lung cancer surgery.Methods One hundred and fifteen patients under cisplatin-based chemotherapy were randomly divided into the control group ( n =58 ) and the treatment group( n =57 ).For the control group,Azasetron ( day 1-5 ) and dexamethasonewere (day 1-3 )were injected intravenously with a dose of 10 mg/day at half an hour before chemotherapy.For the treatment group,intramuscularinjectionof promethazine (25mg/day,30minsbeforesurgery ) and metoclopramide( 10 mg/day,30 mins before surgery )and intravenous infusion of omeprazole (40 mg/day,45 mins before surgery)were given from day 1 to day 5 in addition to the treatment for the control group to relieve chemotherapy-induced acute and late-phased nausea and vomiting.ResultsThere were no significant differences between the two groups in controlling acute nausea and vomiting in terms of complete response rate (Ps ＞0.05 ).However,there were significant effect on late-phased nausea,with an effective rate of 87.7％(50/57) in the treatment group versus 72.4％ (42/58) in the control group at day 2 after treatment( x2 =4.21,P ＜ 0.05 ),and 84.2％ (48/57) vs.67.2％ ( 39/58 ) at day 3 ( x2 =4.49,P ＜ 0.05 ),91.2％ ( 52/57 ) vs.77.6％ (45/58) at day 4 ( x2 =4.05,P ＜ 0.05 ),94.7％ ( 54/57 ) vs.81.0％ ( 47/58 ) at day 5 ( x2 =5.04,P ＜ 0.05 ).Furthermore,there were significant effect on late-phased vomiting,with an effective rate of 91.2％ (52/57)in the treatment group versus 74.1％ (43/58) in the control group at day 2 after treatment ( x2 =5.84,P ＜ 0.05 ),and 91.2％ ( 52/57 ) vs.70.7％ ( 41/58 ) at day 3 ( x2 =7.84,P ＜ 0.05 ),94.7％ ( 54/57 ) vs.79.3％ ( 46/58 ) at day 4 ( x2 =6.03,P ＜ 0.05 ),98.2％ (56/57) vs.87.9％ (50/58) at day 5 ( x2 =5.77,P ＜ 0.05 ).The common side effect in both group were dizzy,headache and coporostasis,with no significant difference [ 15.8％ ( 9/57 )vs.20.7％(12/58),x2 =0.46,P=0.49 ].ConclusionThe combinational medication used in the treatment group prominently reduced the incidence of chemotherapy-induced nausea and vomiting after pneumonectomy,especially the late-phased nausea and vomiting.
