    Background: Endotracheal (ETT) and tracheostomy tube (TT) blockage is a common airway accident in Intensive Care Unit (ICU). Although tube blockage is rarely fatal, it has a major impact on the quality of ICU care and the family of the patient12. The present study is aimed to assess the incidence of ETT/TT tube blockage and associated risk factors including the tube size, shift of tube blockage, type of tube blockage, duration of intubation and frequency of suctioning. The causes of tube blockage and outcome of tube blockage. Objective: To assess the incidence and associated risk factors of endotracheal tube and tracheostomy tube blockage in pediatric, adult surgical and medical intensive care units in Addis Ababa University School of health science Tikur Anbesa specialized hospital. Materials and Methods: After the department of Anesthesiology research committee approval, Institutional based prospective cross sectional study was conducted from March to August, 2018 to assess the incidence and associated risk factors of endotracheal and tracheostomy tube blockage in pediatric, adult medical and surgical ICUs. Data was collected using formatted questionnaire in ICU patients admitted to pediatric, adult medical and surgical ICU during the study period. All admitted patients in ICU who were intubated with ETT or TT had been included in this study whose consent was taken from the family. The collected data was entered, coded using Epi – info software and analyzed through SPSS software 23 version. Result: A total of 276 patients were admitted in ICU, surgical 129, medical 81 and pediatric 66 ICU from this patient 122 were intubated, from those tube blocked, medical 5 (25%), surgical 9 (45%) and pediatric ICU 6 (30%) respectively. The Incidence of ETT/TT blocked was 20(16.4%). From those ETT was16 (80%) and TT blocked was 4(20%) (P=0.042), most cause of tube blocked was mucus 11(55%) then debris 4(20%), and 1(5%) kinked from pediatric ICU. Greater than 7 TDS’ 7(35%) were blocked, so tube blockage higher in number. The degree of ETT/TT blocked was similar between in partial and complete blocked which was 10(50%) vs 10(50%) consecutively (P=0.025), so it is statistical significant. During the night shift tube blockage was 11(55%) slightly high in number, but during day shift, it was 9(45%). Conclusion: The overall incidence of tube blocked was 20(16.4%), so it was higher compare to other studies might been higher setup.
