Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Diagnostic accuracy of perfusion index ratio for resolution of motor block | before the surgery, at 5, 10, 15 and 30 minutes after the block, and at 30, 60, 90 and 120 minutes, and 4, 6, 8, 12, 16 and 24 hours postoperatively | Area under the ROC curve, optimal cut-off value, sensitivity and specificity of the perfusion index ratio (operated hand / contralateral hand) for detecting complete resolution of motor block after infraclavicular brachial plexus block. Complete resolution is defined as Grade 0 on the 4-point upper extremity motor scale (able to raise the extended arm to 90 degrees for 2 seconds). Motor status is assessed by a blinded investigator at each time point. |
| Primary | Diagnostic accuracy of perfusion index ratio for resolution of sensory block | before the surgery, at 5, 10, 15 and 30 minutes after the block, and at 30, 60, 90 and 120 minutes, and 4, 6, 8, 12, 16 and 24 hours postoperatively | Area under the ROC curve, optimal cut-off value, sensitivity and specificity of the perfusion index ratio (operated hand / contralateral hand) for detecting complete resolution of sensory block after infraclavicular brachial plexus block. Complete resolution is defined as pinprick sensation equal to that of the contralateral hand. Sensory status is assessed by a blinded investigator at each time point. |
| Secondary | Perfusion index ratio cut-off for first regression of motor block | Before the surgery, at 5, 10, 15 and 30 minutes after the block, and at 30, 60, 90 and 120 minutes, and 4, 6, 8, 12, 16 and 24 hours postoperatively | Area under the ROC curve, optimal cut-off value, sensitivity and specificity of the perfusion index ratio (operated hand / contralateral hand) for detecting the first regression of motor block after infraclavicular brachial plexus block. First regression is defined as the first decrease in motor grade on the 4-point upper extremity motor scale from the maximal block level, assessed by a blinded investigator. |
| Secondary | Perfusion index ratio cut-off for first regression of sensory block | Before the surgery, at 5, 10, 15 and 30 minutes after the block, and at 30, 60, 90 and 120 minutes, and 4, 6, 8, 12, 16 and 24 hours postoperatively | Area under the ROC curve, optimal cut-off value , sensitivity and specificity of the perfusion index ratio (operated hand / contralateral hand) for detecting the first regression of sensory block after infraclavicular brachial plexus block. First regression is defined as the first return of pinprick sensation in the operated hand, assessed by a blinded investigator. |
| Other | Relationship between perfusion index ratio and clinical block status | Before the surgery, at 5, 10, 15 and 30 minutes after the block, and at 30, 60, 90 and 120 minutes, and 4, 6, 8, 12, 16 and 24 hours postoperatively | Correlation between the perfusion index ratio and motor grade (4-point upper extremity motor scale) and sensory block status (pinprick) at each time point, using methods that account for repeated measurements within patients. |
| Other | Duration of sensory and motor block | Before the surgery, at 5, 10, 15 and 30 minutes after the block, and at 30, 60, 90 and 120 minutes, and 4, 6, 8, 12, 16 and 24 hours postoperatively | Time from completion of the block to first regression and to complete resolution of sensory block (pinprick) and motor block (4-point upper extremity motor scale), assessed by a blinded investigator. |
