AnalgesiaNCT07784426
Tourniquet Pain Prevention During Distal Upper Limb Surgery
A study testing Selective ultrasound guided Intercostobrachial nerve block and Serratus anterior plane block in people with Analgesia, run by Zagazig University.
Trial summary
Post-tourniquet pain remains a common problem. It disturbs the quality of anesthesia during brachial plexus block for distal upper-limb surgery. Current evidence shows that adding an intercostobrachial nerve block using the landmark-based technique can improve analgesia for medial upper-arm procedures. Read more about this study

About this study
Official title: Brachial Plexus With Intercostobrachial Nerve or Serratus Anterior Plane Block for Tourniquet Pain Prevention During Distal Upper-Limb Surgery
Post-tourniquet pain remains a common problem. It disturbs the quality of anesthesia during brachial plexus block for distal upper-limb surgery. Current evidence shows that adding an intercostobrachial nerve block using the landmark-based technique can improve analgesia for medial upper-arm procedures.
Read the detailed description
Post-tourniquet pain remains a common problem. It disturbs the quality of anesthesia during brachial plexus block for distal upper-limb surgery. Current evidence shows that adding an intercostobrachial nerve block using the landmark-based technique can improve analgesia for medial upper-arm procedures. The serratus anterior plane block has also been proposed as an adjunct that may cover the intercostobrachial nerve territory. However, the landmark intercostobrachial nerve technique relies on a blind injection and may give inconsistent results. Moreover, high-quality head-to-head data comparing ultrasound-guided intercostobrachial nerve block with serratus anterior plane block for tourniquet pain prevention are lacking.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Selective ultrasound guided Intercostobrachial nerve blockProcedure or surgery
The patient will be positioned supine with the ipsilateral arm abducted. The ultrasound transducer will be positioned in the axilla along the mid-axillary line to visualize the thoracodorsal artery and vein and the fascia between the latissimus dorsi and serratus anterior muscles. The Intercostobrachial nerve often appears as a small hyperechoic structure lateral to the thoracodorsal vessels.
Serratus anterior plane blockProcedure or surgery
The ultrasound transducer will be placed at the mid-axillary line at the level of the fourth or fifth rib to identify and inject a local anaesthetic drug in the plane between the latissimus dorsi and serratus anterior muscles.
| Study group | Role | What they receive |
|---|---|---|
| Selective ultrasound guided Intercostobrachial nerve block | Active comparator | After a brachial plexus block, participants will receive a selective Intercostobrachial nerve block. The patient will be positioned supine with the ipsilateral arm abducted. The ultrasound transducer will be positioned in the axilla along the mid-axillary line to visualize the thoracodorsal artery and vein and the fascia between the latissimus dorsi and serratus anterior muscles. Receives: Procedure: Selective ultrasound guided Intercostobrachial nerve block |
| Serratus anterior plane block | Active comparator | The patient will be positioned supine with the ipsilateral arm abducted slightly. Under aseptic conditions, the ultrasound transducer will be placed at the mid-axillary line at the level of the fourth or fifth rib to identify the plane between the latissimus dorsi and serratus anterior muscles. Receives: Procedure: Serratus anterior plane block |
What is being measured
The primary outcome is the main question the study is designed to answer.
Tourniquet pain degree
The visual analogue score of tourniquet pain at the end of first 60 minutes of tourniquet inflation with score 10 indicates worst pain and score 0 indicates no pain.
Measured: The first 60 minutes of tourniquet inflation.
Secondary outcomes (1)
Duration of tourniquet application.
The time from tourniquet inflation to tourniquet deflation.
Measured: The first 2 hours intraoperative.
