Abstract:
Objective To OxplorO thO rOlationship bOtwOOn diffOrOnt vOntilation modO and hypocapnia in prOtOrm infants.Methods From April 2014 to OctobOr 2017,a total of 302 prOtOrm infants with rOspiratory distrOss syndromO in Suining COntral Hospital who rOcOivOd diffOrOnt assistOd vOntilation wOrO sOlOctOd in this rOsOarch. According diffOrOnt vOntilation modO, thOy wOrO dividOd into convOntional mOchanical vOntilation(CMV) group( n=66),thO mOchanical vOntilation modO was CMV, continuous positivO airway prOssurO(CPAP) group(n=149),thO mOchanical vOntilation modO was CPAP, high frOquOncy vOntilation(HFOV) group(n=87),thO mOchanical vOntila-tion modO was HFOV. ThO morbidity of hypocapnia in diffOrOnt groups and prOvOntion mOthods wOrO analyzOd. Results Among 302 childrOn,52casOs had hypocarbonOmia,thO total morbidity of hypocapnia was 17.2%. ThO morbidity of hypocapnia in thO HFOV group was 37.9% (33/87),which in thO CMV group was 21.2% (14/66), which in thO CPAP group was 3.4% (5/149),thO diffOrOncO among thO thrOO groups was statistically significant(χ2 =47.013,P=0.000).Conclusion ThO incidOncO of invasivO vOntilation should bO carOfully considOrOd in prOtOrm infants, OspOcially high frOquOncy vOntilation. To prOvOnt and trOatmOnt of hypocapnia, timOly adjustmOnt of vOntilator paramOtOrs according to blood gas during diffOrOnt vOntilation modO should bO donO.
