Interfascial Pressure Into Ultrasound Guided Anterior Quadratus Lumborum Block Application

The block has been shown to be the result of abdominal analgesia as a result of application between the quadratus lumborum (QL) muscle and the leaves in the thoracolumbar fascia.

In this block, local anesthetic drugs are administered between the quadratus lumborum (QL) muscle and the anterior leaf in the thoracolumbar fascia.

In this way, it has been reported that it provides a good analgesia as it relieves somatic pain better in upper and lower abdominal surgeries.

About this study

The mechanism of QLB analgesic contains many theories. This study includes the research relationship between the effect of fascial pressure and the success of the association block. We will use the ultrasound guided anterior Quadratus Lumborum Block. A peripheral nerve block catheter will be placed between the quadratus lumborum muscle and the psoas muscle with ultrasound.The pressure between the fascia and the pressure line added to the catheter tip will be measured.A peripheral nerve block catheter will be placed between the quadratus lumborum muscle and the psoas muscle with ultrasound. The pressure between the fascia and the pressure line added to the catheter tip will be measured.

Treatment and study plan

inter-fascial pressure

Device

The pressure between the fascia and the pressure line added to the catheter tip will be measured.

Primary outcomes

  1. Interfascial Pressure (mm/hg)

    Time frame: 24 hours.

    İnterfascial pressure will be measured the postoperative 24. hours through catheter.

Secondary outcomes

  1. sensory block level

    Time frame: peroperative 3 hours

    After the application, the sensory block level at the 30 minutes after the block application and 30 minutes after the operation will be determined by cold test.

  2. Visual Analog Scale

    Time frame: Postoperative 24 hours

    Visual Analog Scale was used for pain.Pain intensity was measured using 0-10 cm visual analogue scale (VAS). (0=no pain, 10=intolerable pain)

  3. analgesic use

    Time frame: Postoperative 24 hours

    analgesic use
