Rate of extubation success after applying spontaneous breathing trial (SBT) protocol in National Guard Health Affairs

Abstract

The objective of this study is to assess extubation success (no need for reintubation within 48 h) tendency after applying spontaneous breathing trial protocol in National Guard Health Affairs (NGHA). This is a prospective study done on extubated patients who undergo a spontaneous breathing trial (SBT) prior to extubation in King Abdulaziz Medical City (KAMC), Riyadh, NGHA. We used stratified sampling technique to include patients both males and females who were intubated, between 18 and 90 years old, and with FIO2 requirement < 40%. Data was collected by data collection form and analyzed by SPSS. We collected information about 93 patients; their mean age was 58.19 years. SBT protocol was applied correctly (on KAMC hospital criteria) on 42 patients. 85.7% of patients who received correct SBT had successful extubation, while patients who received wrong SBT had a 75.5% extubation success. Moreover, vital signs for patients who had correct SBT was decreasing within the normal range after 48 h. However, it increased for patients who had wrong SBT. Their ABG after extubation was normal for 51.6% of all participants, although most of them had correct SBT. In conclusion, correct application of SBT protocol was followed by higher rate of extubation success and normal vital signs and ABG results.
