Registered outcomes 10
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Total Cerebral Desaturation Burden (AUC) | From baseline measurement before the nerve block until 10 minutes after return to the supine position. | The area under the curve below the desaturation threshold, defined as 80% of baseline regional cerebral oxygen saturation (rSO₂). AUC will be calculated separately for each hemisphere; the mean of the two hemispheres will be used for the primary comparison. Only desaturation episodes lasting at least 15 seconds will be included. The unit is %·min. | ClinicalTrials.gov |
| Secondary | Incidence and Number of Cerebral Desaturation Events | From baseline measurement before the nerve block until 10 minutes after return to the supine position. | Proportion of participants with, and number of, cerebral desaturation events, defined as a decrease in rSO₂ of at least 20% from baseline lasting at least 15 seconds. | ClinicalTrials.gov |
| Secondary | Total Time Below the Cerebral Desaturation Threshold | From baseline measurement before the nerve block until 10 minutes after return to the supine position. | Total time during which rSO₂ remains below 80% of baseline. | ClinicalTrials.gov |
| Secondary | Minimum Right and Left Cerebral rSO₂ | From baseline measurement before the nerve block until 10 minutes after return to the supine position. | Minimum rSO₂ values recorded from the right and left frontal hemispheres; values will be assessed separately. | ClinicalTrials.gov |
| Secondary | Ipsilateral and Contralateral Cerebral Desaturation Burden | From baseline measurement before the nerve block until 10 minutes after return to the supine position. | AUC below the desaturation threshold in the cerebral hemisphere ipsilateral and contralateral to the operated shoulder. | ClinicalTrials.gov |
| Secondary | Incidence of Intraoperative Hypotension and Bradycardia | During the intraoperative period. | Proportion of participants with hypotension, defined as a decrease in baseline systolic blood pressure of more than 20% or MAP below 65 mmHg, and bradycardia, defined as heart rate below 50 beats/min. | ClinicalTrials.gov |
| Secondary | Total Intraoperative Ephedrine and Norepinephrine Dose | During the intraoperative period. | Total ephedrine dose in mg and total norepinephrine dose in µg administered intraoperatively. | ClinicalTrials.gov |
| Secondary | Post-Anesthesia Care Unit Length of Stay | Perioperative period (immediate postoperative recovery, from post-anesthesia care unit admission to discharge). | Time elapsed, in minutes, from postoperative admission to the post-anesthesia care unit to discharge to the surgical ward. Patients are discharged when the Modified Aldrete Score reaches 9 or higher. | ClinicalTrials.gov |
| Secondary | Modified Aldrete Score at Post-Anesthesia Care Unit Discharge | Perioperative period (at discharge from the post-anesthesia care unit). | The Modified Aldrete Score is recorded at discharge from the post-anesthesia care unit to the surgical ward. The scale assesses activity, respiration, circulation, consciousness, and oxygen saturation. Each component is scored from 0 to 2, yielding a total score ranging from 0 to 10. Higher scores indicate better physiological recovery from anesthesia. Patients are discharged when the total score reaches 9 or higher. | ClinicalTrials.gov |
| Secondary | Assessment of cognitive functions at the 24th postoperative hour | At the 24th postoperative hour | A Mini-Mental State Examination was performed at the 24th postoperative hour to assess cognitive functions. | ClinicalTrials.gov |
