Objective To explore the application effect of sedation scheme based on different RASS scores in patients with septic shock.Methods A total of 82 patients with septic shock in People's Hospital of Xinjiang Uygur Autonomous Region from January 2019 to January 2021 were selected and randomly divided into study group (n=41) and control group (n=41). Two groups of patients were given symptomatic intervention after entering ICU, on the basis of which, the corresponding sedation scheme was given according to RASS score. The RASS score of the study group was maintained at -3~-4, while the RASS score of the control group was maintained at 0~-2. The levels of cardiac troponin I (cTnI), cTnT, brain natriuretic peptide (BNP), blood gas index (PaO2、PaCO2), immune function index (NK、CD3+、CD4+), sofa, Apache Ⅱ score, mechanical ventilation time, ICU stay time, 28 day mortality rate were counted before and after sedation.Results After three days of sedation, the levels of cTnI, cTnT and BNP in the two groups were lower than those before sedation, and the difference in the study group was lessobvious than that in the control group (P<0.05).After three days of sedation, the PaO2 level in the two groups was higher than that before sedation, and the PaO2 level in the study group was higher than that in the control group, the PaO2 level was lower than that in the control group, and the difference was greater than that in the control group (P<0.05).After the intervention, the levels of NK in the two groups were lower than those before the intervention, and the levels of CD3+, CD4+ were higher than those before the intervention, and the study group was better than the control group (P<0.05).The scores of sofa and Apache Ⅱ in the two groups were lower than those before sedation, and the scores in the study group were lower than those in the control group (P<0.05). The time of mechanical ventilation and ICU stay in the study group were shorter than those in the control group (P<0.05), and there was no significant difference between the 28 day mortality (14.63%) and the control group (19.51%) (P>0.05).Conclusion Maintaining RASS score between -3 and -4 in sedation intervention for septic shock patients can protect myocardium, regulate blood gas status and immune function, alleviate the patient's condition, and shorten the time of mechanical ventilation and ICU stay. |
