Study On Humidification Effect Of Different Humidification Methods On Tracheotomy In Traumatic Brain Injury

Objective:To compare the humidification oxygen therapy system and heat exchanger of ICU craniocerebral injury and different humidification effect and prognosis of the patients with tracheotomy,so as to select the optimum airway humidification,make to take empirical effective treatment in patients with traumatic brain injury,for the choice of reasonable,convenient and effective to provide reference for clinical wet the way.Methods:By means of literature search,we compared the different clinical features of the moist heat exchanger and the humidification oxygen therapy system.60 cases of brain in January 2016 to June 2017 ICU in our hospital from injury after tracheotomy in random parallel,average packet method,divided into experimental group and control group,30 patients in each group.Inclusion criteria:Patients with traumatic brain injury has been out of the ventilator treatment but no plugging tracheotomy(single disease),age 40-70 years old,GCS score less than 8 points,the use of ventilator assisted treatment for more than 3 days,the research on the voluntary participation;exclusive criteria:systemic infection or serious pulmonary infection patients,COPD patients with severe bronchial fistula patients,the GCS score less than 3 points,with the from the ventilation is the third degree(severe thick sputum).There was no significant difference between the two groups in age,sex,hypertension,diabetes mellitus,smoking history,heart disease and other basic diseases.The experimental group was treated with MR850 humidifier,venturi air oxygen mixing valve and heating pipeline,and the control group was treated with the wet heat exchanger.The two groups were observed in patients with HR,DBP,SBP,RR,SaO2,PaCO2,PaO2,and sputum suction volume,daily times of sputum suction and complications(sputum,pulmonary infection,airway mucosal bleeding)occurrence analysis,two groups of different humidification of craniocerebral injury patients with tracheotomy airway humidification effect and prognosis of the difference.Results:After treatment of different humidification methods in two groups of patients,HR,DBP and RR of repeated measurement data were analyzed by analysis of variance the difference was statistically significant(P<0.05).The patients in the control group after treatment of HR and RR compared with the control group,to a certain extent,accelerate the DBP increased;oxygen saturation in patients of the two groups after treatment(SaO2)and partial pressure of PaO2 level was significantly different(P<0.05),while the level of PaCO2 in two groups was not statistically significant,the experimental group compared with control group it is easier to maintain higher SaO2 and partial pressure of Pa02 level;two groups of patients after treatment,the sputum volume,on the difference between the number of sputum suction was statistically significant(P<0.05),two groups of patients in the wet treatment are increased sputum,sputum number increase,sputum character in the two group(Ⅲ phlegm cases),complications(sputum,pulmonary infection,airway mucosal bleeding)were no significant difference between the frequency of occurrence of the situation.Conclusion:In the experimental group the humidified oxygen therapy system relative to the control group in the treatment of patients with damp heat exchanger of HR and RR to slow,the patient’s respiratory and blood pressure are more stable,better comfort;experimental group of humidification oxygen therapy system and a control group of patients with oxygen saturation compared to wet heat exchanger the SaO2 and partial pressure of PaO2 level to maintain a high level,although the two groups of patients with PaCO2 values are higher,but the wet treatment of two groups of patients did not appear excessive and insufficient ventilation;two kinds of humidification methods are of phlegm and complications(sputum,lung infection,airway mucosal bleeding)the incidence rate has improved significantly,but between the two groups had no significant difference;the satisfaction of humidification of the experimental group was significantly higher than that of the control group.
