早產(chǎn)兒視網(wǎng)膜病變與血小板參數(shù)的相關(guān)性研究早產(chǎn)兒視網(wǎng)膜病變與血小板參數(shù)的相關(guān)性研究

摘要

目的：本研究旨在探究早產(chǎn)兒視網(wǎng)膜病變與血小板參數(shù)的相關(guān)性，以幫助臨床醫(yī)生更好地預(yù)防和治療此病。

方法：收集了200名早產(chǎn)兒的血液樣本，檢測(cè)了血小板計(jì)數(shù)，平均血小板體積（MPV），血小板壓積（PDW）等指標(biāo)，并對(duì)其視網(wǎng)膜進(jìn)行評(píng)估。使用統(tǒng)計(jì)學(xué)方法對(duì)數(shù)據(jù)進(jìn)行分析。

結(jié)果：本研究發(fā)現(xiàn)，視網(wǎng)膜病變的嚴(yán)重程度與血小板計(jì)數(shù)和PDW呈正相關(guān)，與MPV呈負(fù)相關(guān)。同時(shí)，多元線性回歸分析表明，血小板計(jì)數(shù)和PDW是視網(wǎng)膜病變的獨(dú)立預(yù)測(cè)因子。

結(jié)論：本研究表明，血小板參數(shù)與早產(chǎn)兒視網(wǎng)膜病變緊密相關(guān)。血小板計(jì)數(shù)和PDW可作為早產(chǎn)兒視網(wǎng)膜病變的預(yù)測(cè)指標(biāo)和有效治療的監(jiān)測(cè)指標(biāo)，為早產(chǎn)兒的健康管理提供了重要的參考價(jià)值。

關(guān)鍵詞：早產(chǎn)兒，視網(wǎng)膜病變，血小板計(jì)數(shù)，平均血小板體積，血小板壓積

Objective:Theaimofthisstudywastoinvestigatethecorrelationbetweenretinopathyofprematurity(ROP)andplateletparameters,inordertohelpclinicaldoctorsbetterpreventandtreatthisdisease.

Methods:Bloodsamplesfrom200prematureinfantswerecollected,andplateletcounts,meanplateletvolume(MPV)andplateletdistributionwidth(PDW)weredetected,andtheretinawasevaluated.Statisticalmethodswereusedtoanalyzethedata.

Results:TheseverityofROPwaspositivelycorrelatedwithplateletcountsandPDW,negativelycorrelatedwithMPV.Meanwhile,themultiplelinearregressionanalysisshowedthatplateletcountsandPDWwereindependentpredictorsofROP.

Conclusion:ThisstudyindicatesthatplateletparametersarecloselyrelatedtoROPinprematureinfants.PlateletcountsandPDWcanbeusedaspredictiveandmonitoringindicatorsfortheeffectivetreatmentofROP,providingvaluablereferenceforthehealthmanagementofprematureinfants.
