ABSTRACT
Objective To evaluate the effect of duration of subcutaneous injection on the extent of bruising at injection sites among patients receiving low- molecular weight heparin. Methods Randomized clinical trials and quasi-experimental within-subject design that assessed the effect of subcutaneous duration on the bruising of injection sites were selected in Cochrane library, JBI evidence-based practice medical and nursing database, PubMed biomedical information retrieval platform, Medline general medical literature retrieval database. RevMan5.3 software was used to analyze the data after quality assessment, and data extraction were made for eligible trials. Results A total of 9 trials were included. The results of Meta-analysis supported the 30 s duration injection technique on reducing the rate of bruising of injection sites than 10 s duration injection technique (odds ratio was 0.34,95%confidence interval 0.25-0.47, P 0.05). Conclusions Increasing the length of low-molecular weight heparin subcutaneous injection can reduce the rate of bruising. While it could not effectively reduce the area.
ABSTRACT
Objective To observe the effect of smoking cessation intervention combined with salmeterol and fluticasone pro‐pionate powder for inhalation on chronic obstructive pulmonary disease (COPD) patients with clinical symptoms and pulmonary function .Methods Totally 78 male long‐term smoking cases were randomly divided into control group(n= 40)and observation group(n=38) .The control group was treated with the ophylline sustained‐release tablets ,shah mette lo fluticasone;observation group received smoking cessation intervention .The smoking rate ,symptoms ,acute exacerbation ,life score and lung function (FEV1 ,FEV1/FVC) ,adverse reactions of two groups were observed .Results Two groups of symptoms were all improved ,but the observation group was better (P<0 .05) .FEV1 ,FEV1/FVC ,acute exacerbation ,scores were improved ,but the observation group was better(all P<0 .05);quit rates in the observation group was better than that of the control group(P<0 .05);and did not found adverse reactions .Conclusion The effect of smoking cessation intervention combined with salmeterol and fluticasone propionate powder for inhalation efficacy in the treatment of COPD is distinct ,can improve the pulmonary function and symptoms .
