Combined RSBI, TOF, and BIS for Prediction of Extubation Success

This prospective observational study aims to evaluate the predictive value of the combined use of the rapid shallow breathing index, train-of-four ratio, and bispectral index for extubation success after general anesthesia. Adult patients undergoing elective surgery under general anesthesia and planned for extubation in the operating room will be included. Before extubation, RSBI, TOF ratio, BIS value, respiratory parameters, and relevant perioperative data will be recorded. The decision to extubate will be made by the attending anesthesiologist according to routine clinical practice and will not be altered by the study protocol. Patients will be followed for 30 minutes after extubation to assess extubation success or the development of complications such as desaturation, laryngospasm, need for airway intervention, mask ventilation, or reintubation. The primary aim is to determine whether the combined RSBI, TOF, and BIS model predicts extubation success more accurately than each parameter alone.
