Abstract

This predictive study aimed to use existing data to investigate predictive factors for extubation in patients with respiratory failure. The samples included 145 medical patients using purposively sampling from those whose records showed respiratory failure histories and were intubated using medical ventilators in the Intensive Care Unit at Singburi Hospital, from October 2013 to December 2016. The data were collected using 1) personal information and patients’ medical history record forms, 2) record forms of predictive factors for extubation including laryngeal edema and cough strength, and 3) extubation outcome record form. The tool content validity index (CVI) of 1.00 was verified by three experts. Descriptive statistics, chi-square test, and binary logistic regression were used for data analysis. 

                The result revealed that extubation in 74.48% of the samples was successful. Statistically significant predictive factors (p<.05) were age (b= 1.306), laryngeal edema (b= 1.601), and cough strength (b= 3.187); all of which could together predict 32% of the extubation outcomes (Cox and Snell R²=.32). It was recommended that before extubation, health care providers should assess essential predictors to ensure the patients had no laryngeal edema and satisfactory cough strength to reduce reintubation.
