Application of supervised early warning intervention combined with closed suction method in emergency patients with severe pneumonia and respiratory failure
Objective To explore the application value of supervised early warning intervention combined with closed suction method in emergency patients with severe pneumonia and respiratory failure.Methods This was a retrospective study including 88 emergency patients with severe pneumonia and respiratory failure treated with mechanical ventilation in our hospital from May 2020 to April 2023.They were randomized 1:1 to closed suction method(control group)or supervised early warning intervention combined with closed suction method(observation group).The blood gas indexes(arterial partial pressure of oxygen[PaO2],arterial partial pressure of carbon dioxide[PaCO2])at day 0,3 of intervention,sputum viscosity at days 1,3,and 5 of intervention,complications,and hospitalization related indexes(mechanical ventilation time,ICU time,hospitalization time)were compared between groups.Results At days 3 of intervention,both groups showed significantly increase PaO2 and a decrease in PaCO2,with inter group significant difference(P＜0.05).The sputum viscosity in the observation group was better than that in the control group at days 1 3 and 5 of intervention(P＜0.05).Compared with the control group,the observation group had significantly lower overall incidence of complications,shorter mechanical ventilation time,ICU stay time,and hospitalization time(allP＜0.05).Conclusion The combination of supervised early warning intervention and closed suction method can improve the blood gas indicators of emergency patients with severe pneumonia and respiratory failure,improve sputum viscosity,reduce the incidence of complications,and help shorten the mechanical ventilation time and hospitalization time of patients.
