• 1 other identifier: FMASU MS 726/2023
• Study Type: observational
• Target: 43
• Locations: 0 countries
• Sites: N/A

Brief Summary

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 .

Conditions

Perfusion Index

Keywords

Supraclavicular block; Brachial plexus block; Perfusion index ( PI )

Outcome Measures

Primary Outcomes (2)

• 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.

  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.

• 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.

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

Study Arms (1)

Perfusion index at the blocked & unblocked limb

The Perfusion Index 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. In every patient , a comparison between the blocked and unblocked limb was performed .

Other: Measurement of perfusion index after supraclavicular brachial plexus block at blocked & unblocked limb

Interventions

Measurement of perfusion index after supraclavicular brachial plexus block at blocked & unblocked limb OTHER

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 .
