We have carried out a bibliometric analysis and developing of anaesthesia literature,and to determine its growth rule and grow tendency,and to provide the basis for research problems relation with anaesthesia.Methods:We selected(PubMed databases,www.ncbi.nlm.nih.gov/Pubmed)literatures that contained the descriptors anaesthesia in their title or paper.As bibliometric indicators of anaesthesia we calculated the biomedical journals referring to anaesthesia.We applied the principal bibliometric indicators:Price's and Bradford's laws on the increase or dispersion of scientific literature,the participation index of languages and the journals.By means of manual coding,documents were classified according to documents of study and to Statistical analysis.Results:From 1866 to 2009,there were 281 326 literatures in the PubMed database including literatures of anaesthesia.According to PubMed database literature type,it is including Review(21 710),Randomized Controlled Trial(22 528),Practice Guideline(339),Meta-Analysis(439),Letter(21 635),Editorial(3 429),Clinical Trial(31 581),others(180 665).In PubMed includes the anesthesiology literature to divide into PubMed Central(10 170),MEDLINE(269 162)and other(1 994);According to Journal Groups,divides into Nursing Journals 4 258,Dental journals 10 974,Core clinical journals 63 371,other 202 723;With Humans correlation literature 191 900,Animals correlation literature 63 371,other 202 723.From 1966 to 2005,the literatures increase the approximate straight line(y=5180.5x+3685.8,R2=0.9458).Chinese anaesthesia literatures in PubMed started from 1956,and increasing obviously since 1986,but its equation close exponent sign(y=4.0874e0.4279x,R2=0.7497).The anaesthesia literatures by English primarily(221 727/281 326,78.81%),Chinese publication literatures arranges at 9th(2 309/281 327,0.82%).In PubMed 24 periodicals correlation anesthesiology(SCI-indexed)includes literature 95 155(32.66%).Conclusion:The literatures of anaesthesia are year by year slow increases progressively,approximate straight line(y=5180.5x+3685.8)during 1966-2005,and showing research anaesthesia to be at a more popular stage continuously since near half century.
