Brief Summary

The infraclavicular nerve block, which is frequently preferred in upper extremity surgeries, provides additional advantages such as reduction in opioid consumption by providing analgesic effect in the postoperative period as welll. The success of peripheral nerve blocks is usually assessed by subjective feedback from the patient, and patient cooperation is needed. The aim of this study is to assess whether the perfusion index level, which can be measured noninvasively, can be a predictor of the infraclavicular block success.

Conditions

Carpal Tunnel Syndrome; Perfusion Index

Keywords

Infraclavicular block; Perfusion index; Ultrasonography; Block assessment

Outcome Measures

Primary Outcomes (1)

• Evaluation of whether perfusion index is a reliable and objective method to indicate block success

  Perfusion index was measured up to 6 hours after the procedure.

  6 hours postprocedurly

Secondary Outcomes (1)

• Determining of a cut-off value for PI and PI ratio for a successful block.

  Up to 6 hours after the procedure

Study Arms (2)

Blocked arm

ACTIVE COMPARATOR

The investigators performed an infraclavicular nerve block to the operated arm group to provide anesthesia.

Procedure: Infraclavicular nerve block

Unblocked arm

ACTIVE COMPARATOR

The upper extremity without block was assigned as the control group, and a comparison was made between the two upper extremities.

Procedure: Without nerve block

Interventions

Infraclavicular nerve block PROCEDURE

The investigators performed an infraclavicular nerve block to the operated arm group to provide anesthesia.

Blocked arm

Without nerve block PROCEDURE

The upper extremity without block was assigned as the control group, and a comparison was made between the two upper extremities.

Unblocked arm
