ABSTRACT
Objective To compare the prognoses in pregnancy women receiving routine perineal shaving and non perineal shaving before vaginal delivery through meta analysis.Methods The randomized controlled trials or non-randomized controlled trials for comparing the prognoses in pregnancy women receiving routine perineal shaving and non perineal shaving before vaginal delivery were retrieved from databases,including Cochrane Library,PubMed,EMbase,SCI,Ovid,CBM,Wanfang,VIP and CNKI,till December 2015.The studies were selected according to the inclusion and exclusion criteria,and the data were extracted and evaluated by two reviewers independently.The Meta-analysis was conducted via RevMan 5.2.6 software.Results A total of 6 studies (including three articles in English and three ones in Chinese) including 1 924 delivery women were included,1 083 cases in the perineal shaving group and 841 cases in the non perineal shaving group.No statistically significant difference was found in the incidence rate of fever after delivery between the perineal shaving group and the non perineal shaving group[Z=0.57,P=0.57,RR=1.14,95 ％ CI(0.73,1.76)],and there was no statistically significant difference in post-operative wound infection between the two groups [Z=0.43,P=0.66,RR=1.11,95％CI(0.69,1.78)].Conclusion Perineal shaving may be not an essential nursing intervention before vaginal delivery.
ABSTRACT
Objective To systematically evaluate the effectiveness and safety of laparoscopic radical cystectomy (LRC) versus open radical cystectomy (ORC).Methods The databases of Cochrane Library , PubMed, EMbase, SCI, Ovid, CBM, WanFang Data Knowledge Service Platform , VIP Information Chinese Science and China National Knowledge Infrastructure , were searched to collect the randomized controlled trails ( RCTs) and non-RCTs about LRC versus ORC for the treatment of muscle invasive bladder cancer . The retrieval time span was from inception to May 2013.The studies were screened according to the inclusion and exclusion criteria , the data were extracted and the quality was evaluated by 2 reviewers independently.The meta-analysis was conducted using RevMan 5.2.6 software.Results A total of 13 non-RCTs involving 783 patients were included .The meta-analysis showed that comparing with ORC , LRC had lesser intraoperative blood loss [MD =-466.85,95%CI( -603.33, -330.37), P 0.05 ) .Conclusions LRC is safe and feasible for treating muscle invasive bladder cancer when its indications are strictly controlled .However, for the quantity and quality limitation of the involved studies , this conclusion still requires to be further proved by large and high quality studies.
