About this study

Official title: Peripheral Perfusion Index as a Predictor of Successful Supraclavicular Brachial Plexus Block in Patients Undergoing Hand Surgeries

Aim of the study is to determine the best cut off value for the PI and PI ratio for predication of successful supraclavicular brachial plexus block in young and middle age patients undergoing hand surgeries .

Read the detailed description
  • The supraclavicular nerve block was performed under guidance of a linear transducer (8-14 MHz; Acuson x300; Siemens Healthcare, Seoul, Korea) over the supraclavicular fossa in the coronal oblique plane immediately superior to the midclavicular point. The block was induced in the semi-sitting position, with the head of the patient turned away from the side to be blocked.
  • The PI was measured using Masimo SET pulse oximeter, applied on the index finger. The PI was recorded at baseline and at 10, 20, and 30min after local anaesthetic injection in both the blocked limb and the contralateral unblocked limb using two separate oximeters.
  • The PI ratio was calculated as the ratio between the PI at 10min after injection and the baseline PI. In every patient, a comparison between the blocked and unblocked limb was performed.
  • PI was recorded at baseline and at 10, 20, and 30 min after local anaesthetic injection in both the blocked limb and the contralateral unblocked limb.
  • PI ratio was calculated as the ratio between the PI at 10 min after injection and the baseline PI.
  • Vital data (Blood pressure, Heart rate, SPO2) was recorded before giving the block and at 10, 20, and 30 min after local anaesthetic injection and at the end of the operation.

  • Measurement of perfusion index after supraclavicular brachial plexus block at blocked & unblocked limbOther

    The PI (Perfusion Index) was measured using Masimo SET pulse oximetry applied on the index finger. The PI was recorded at baseline and at 10 , 20 , and 30 min after local anaesthetic injection in both the blocked limb and the contralateral unblocked limb using two separate oximeters. The PI ratio was calculated as the ratio between the PI at 10min after injection and the baseline PI. In every patient, a comparison between the blocked and unblocked limb was performed .

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cut off value for perfusion index ( PI ) for predication of successful supraclavicular brachial plexus block.

    Perfusion index (PI) was recorded at baseline and at 10, 20, and 30 minutes after local anaesthetic injection in both the blocked limb and the contralateral unblocked limb.

    Measured: Perfusion index (PI) was recorded at baseline and at 10, 20, and 30 minutes after local anaesthetic injection in both the blocked limb and the contralateral unblocked limb.

  2. Cut off value for perfusion index (PI) ratio for predication of successful supraclavicular brachial plexus block.

    Perfusion index (PI) ratio was calculated as the ratio between the PI at 10 minutes after injection and the baseline PI.

    Measured: Perfusion index ( PI ) ratio was recorded at baseline and 10 minutes after local anaesthetic injection

Questions about this trial

What is this clinical trial studying?

An observational study of Perfusion Index, run by Ain Shams University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 6 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cut off value for perfusion index ( PI ) for predication of successful supraclavicular brachial plexus block. (time frame: Perfusion index (PI) was recorded at baseline and at 10, 20, and 30 minutes after local anaesthetic injection in both the blocked limb and the contralateral unblocked limb.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Aug 2024; AzTrials last refreshed its copy on 7 Nov 2026.
