ObjectiveTo explore the anesthetic effect of Ropivacaine at different concentrations by subarachnoid block in cesarean section.MethodsFrom January 2016 to February 2017,120 pregnant women undergone cesarean section were enrolled as research objects.According to the different therapeutic methods,the patients were evenly divided into high concentration group(0.5%)and low concentration group(0.375%),60 cases in each group.In the high concentration group,Ropivacaine in a high concentration via subarachnoid block was used,while in the low concentration group,a low concentration Ropivacaine via subarachnoid block was adopted.The anesthetic effect,the onset time and sustained time of motor block,the onset time and sustained time of sensory block,and incidence of adverse reaction in the two groups were compared.ResultsThe anesthetic effects were compared between the two groups,the differences were not significant(P>0.05).The the onset time of motor block and sensory block were compared between the two groups,the differences were not significant(P>0.05).However,the sustained time of motor block and sensory block in the low concentration group was shorter than those in the high concentration group,the differences were statistically significant(P<0.05).The incidence of adverse reactions in the low concentration group was less than that in the high concentration group,the difference was statistically significant(P<0.05).ConclusionThere is no significant difference in the anesthetic effect between low and high concentrations of Ropivacaine in the treatment of cesarean section by subarachnoid block.Although the sustained time of block is short,the adverse reactions are few and the safety is high,which is worthy of promotion.
ObjectiveTo analyze the application effect of platelet antibody screening technique in the differential diagnosis of idiopathic thrombocytopenic purpura (ITP)and aplastic anemia (AA).MethodsA total of 480 cases with AA,ITP patients and healthy subjects from February 2014 to August 2016 in our hospital were selected.Blood cell analyzer and platelet antibody(PA IgG)screening were used to compare the results of PA IgG in each group,and the relationship between AA and ITP and platelet transfusion refractoriness was evaluated.ResultsThe positive rate of PA IgG in the ITP group(63.0%)was higher than that in the AA group(35.7%),with significant difference(P<0.05).The ineffective rate of platelet transfusion of PA IgG positive patients in the AA group was 71.1%,which was higher than 13.6%of negative patients,with significant difference(P<0.05).The ineffective rate of platelet transfusion of PA IgG positive patients in the ITP group was 64.4%,which was higher than 23.0%of negative patients,with significant difference(P<0.05).The ineffective rate of platelet transfusion in the AA group with PA IgG positive matching patients was 19.0%,which was lower than 100.0%of patients without matching type,with significant difference(P<0.05).The ineffective rate of platelet transfusion in the ITP group with PA IgG positive matching patients was 11.1%,which was lower than 100.0%of patients without matching type,with significant difference (P<0.05).ConclusionPlatelet matching can improve the clinical infusion effect.Platelet antibody screening can provide reference for the differential diagnosis of AA and ITP.
