Abstract:
Objective To explore the effect of humidified high flow nasal cannula (HHFNC) in neonatal with severe pneumonia.Methods Forty-two cases of neonatal with severe pneumonia according to different treatment methods were divided into treatment group (20 cases) and control group (22 cases).Treatment group was given HHFNC,control group was given the wet bottle oxygen nasal cannula or mask.Disappearance of symptoms and hospital stay in two groups,blood oxygen saturation (SpO2),partial pressure of oxygen (PaO2),partial pressure of earbondioxidc (PaCO2) and respiratory rate in treatment group before and after the application of HHFNC were compared.Results The effective rate in treatment group was significantly higher than that in control group [90.00％ (18/20) vs.63.64％ (14/22)],which reached statistical significance (P ＜0.05).Disappearance of symptoms and hospital stay in treatment group were shorter than those in control group,and mechanical ventilation rate was lower than that in control group [10.00％(2/20) vs.45.45％(10/22)],which reached statistical significance (P ＜ 0.05).SpO2 and PaO2 at application of HHFNC after 12,24 h and 1 h after evacuation of HHFNC were significantly increased eompared with those before [0.921 ± 0.027,0.955 ± 0.021,0.958 ± 0.016 vs.0.865 ± 0.045; (83.4 ± 28.3),(89.8 ±20.4),(92.8 ±12.6) mmHg (1 mmHg =0.133 kPa) vs.(52.8 ±10.1) mmHg],PaCO2 at application of HHFNC after 24 h and 1 h after evacuation of HHFNC were significantly reduced compared with those before [(46.1 ±6.3),(43.7 ±7.2) mmHg vs.(59.7 ± 8.3) mmHg],which reached statistical significance (P ＜0.05).Respiratory rate was decreased with the treatment time,which reached statistical significance (P＜ 0.05).Conclusion Application of HHFNC in neonatal with severe pneumonia is effective and woorth promoting.
