摘要
目的 探讨前馈控制理念下的分级干预对急诊重症机械通气患者的影响。方法 选取2021年1月-2023年10月南昌市人民医院收治的150例急诊重症机械通气患者,以组间基本特征具有可比性的原则分为观察组与对照组,各75例,对照组实施分级干预,观察组实施基于前馈控制的分级干预,两组均干预至患者转入普通病房。重点观察对比两组干预前、干预后血气分析指标,并比较两组住院相关指标[机械通气时间、急诊重症监护室(EICU)入住时间]、撤机成功率及并发症发生情况。结果 干预前,两组患者血气分析指标动脉血氧分压(PaO_(2))、氧合指数(OI)、动脉血二氧化碳分压(PaCO_(2))水平比较,差异均无统计学意义(P>0.05);干预后,观察组患者PaO_(2)、OI水平均高于对照组,而PaCO_(2)水平低于对照组,差异有统计学意义(P<0.05)。观察组患者EICU入住时间、机械通气时间均短于对照组,差异有统计学意义(P<0.05)。观察组撤机成功率高于对照组,差异有统计学意义(P<0.05)。观察组并发症发生率低于对照组,差异有统计学意义(P<0.05)。结论 急症重症机械通气患者实施前馈控制理念下的分级干预可改善其血气指标,缩短EICU入住时间、机械通气时间,且可提高撤机成功率,降低并发症发生风险。
Objective To explore the effect of graded intervention under the concept of feed-forward control on emergency critically ill mechanically ventilated patients.Methods 150 cases of emergency critical care mechanical ventilation patients admitted to Nanchang People's Hospital from January 2021 to October 2023 were selected,and divided into 75 cases each in an observation group and a control group based on the principle of comparability of basic characteristics between the groups,the control group implemented graded intervention,and the observation group implemented graded intervention based on feed-forward control,and the two groups intervened until the patients were transferred to the general ward.Focusing on the observation and comparison of blood gas analysis indexes before and after intervention,and comparing the two groups'hospitalisation-related indexes[mechanical ventilation time,emergency intensive care unit(EICU)admission time],the success rate of machine withdrawal and the occurrence of complications.Results Before intervention,the levels of arterial partial pressure of oxygen(PaO_(2)),oxygenation index(OI),and arterial partial pressure of carbon dioxide(PaCO_(2))of the blood gas analysis indexes of the patients in the two groups were compared,and the differences were not statistically significant(P>0.05);after intervention,the levels of PaO_(2) and OI of the patients in the observation group were higher than those of the control group,while the level of PaCO_(2) was lower than that of the control group,and the differences were statistically significant(P<0.05).The EICU admission time and mechanical ventilation time of patients in the observation group were lower than those in the control group,and the difference was statistically significant(P<0.05).The success rate of machine withdrawal in the observation group was higher than that in the control group,and the difference was statistically significant(P<0.05).The complication rate of the observation group was lower than that of the control group,and the difference was statistically significant(P<0.05).Conclusion The implementation of graded intervention under the concept of feed-forward control in patients with acute critical care mechanical ventilation can improve blood gas indexes,shorten the EICU admission time and mechanical ventilation time,and can improve the success rate of withdrawal and reduce the risk of complications.
