The Study On The Moist Liquid And Humidification Method Of The Patients After Laryngectomy

Goal (1)To compare humidification effect、the number of sputum suction per day、the incidence of sputum scab and the patients’comfort level of different moist liquids (0.9%sodium chloride and0.45%sodium chloride) after laryngectomy.(2) To compare humidification effect、the number of sputum suction per day、the incidence of sputum scab and the patients’ comfort level of different humidification methods (intermittent humidification and continuous humidification with microcomputer automatic-control input pump) after laryngectomy.(3) To compare the incidence of complications and the patients’hospitalization expenses and length of time of different moist liquids and different humidification methods after laryngectomy.Method This study was carried out at Shanghai Eye&ENT hospital, using qualitative research. A total sample of124patients who suffered from laryngeal cancer was included, and the patients were devided equally into four groups. The first group of patients dripped0.9%sodium chloride solution intermittently and the second group of patients dripped0.45%sodium chloride solution intermittently. The third group of patients was using continuous humidification with0.9%sodium chloride solution while the fourth group using continuous humidification with0.45%sodium chloride solution. The research of Group A and Group B was carried out at the same time in differerent wards. And the research of Group A and Group B was carried out at the same time in differerent wards. Self-designed questionnaire was used to collect the patients’demographic data and the information about the disease. And self-designed questionnaires about patients’ humidification effect and their comfort level were used to compare the events. Data analyses were performed with SPSS statistical software.Results (1) The patients’ humidification conditions include humidification level、the number of sputum suction per day and the incidence of sputum scab. After statistics, there was significant difference of the number of sputum suction per day and the incidence of sputum scab of the first and the second day after the operation. On the first day, the number of sputum suction of Group A was3.00±1.31; in Group B, the number was4.03±2.06; the number of sputum suction of Group C was2.94±1.57; the number of sputum suction of Group D was3.06±2.02. On the second day, the number of sputum suction of Group A was2.94±1.09,3cases suffered from sputum scab in Group A; in Group B, the number was4.61±2.92and5; the number of sputum suction of Group C was3.29±2.47,2cases suffered from sputum scab in Group C; the number of sputum suction of Group D was2.84±1.42, nobody had sputum suction that day.(2) There was significant difference of the patients’comfort level, the score of that of Group A was51.71±4.14in humidification,26.06±5.70in sputum suction, and the total score was77.77±8.17; the score of that of Group B was53.84±3.85in humidification,26.06±5.70in sputum suction, and the total score was82.03±6.04; the three scores of Group C was57.58±2.08、29.84±4.05and87.42±5.05, which of Group D was57.94±1.91、29.84±2.68and87.77±3.54.(3) There was no significant difference of the patients’ complications after the operation.(4) There was no significant difference of the patients’ hospitalization expenses and length of time.Conclusion (1) There was no significant difference of the humidification effect of the patients after the operation.(2) Using microcomputer automatic-control input pump to drip0.45%sodium chloride solution could decrease the number of sputum suction per day and the incidence of sputum scab.(3) As well, the patients’ comfort level of Group B was the best.(4) After laryngectomy, there was no significant difference of the incidence of complications.(5) Using microcomputer automatic-control input pump as humidification method wouldn’t increase the patients’ hospitalization expenses and length of time.
