Trial summary

Erector spinae plane (ESP) block is a novel block developed by Forero to treat severe neuropathic pain and was firstly reported in 2016. Anatomical and radiological investigations in fresh cadavers indicate that its site of action is likely at the dorsal and ventral rami of the thoracic spinal nerves. Read more about this study

About this study

Official title: Bilateral Ultrasound-Guided Erector Spinae Plane Block For Postoperative Analgesia in Breast Reduction Surgery: A Prospective, Randomized and Controlled Trial

Erector spinae plane (ESP) block is a novel block developed by Forero to treat severe neuropathic pain and was firstly reported in 2016. Anatomical and radiological investigations in fresh cadavers indicate that its site of action is likely at the dorsal and ventral rami of the thoracic spinal nerves. The ESP block has a clear and simple sonoanatomy, it is easy to perform, not time consuming and generally well tolerated by the patients. So, the investigators believed that the ESP block may be an effective and safer alternative to paravertebral block, epidural analgesia and other myofascial thoracic wall blocks in breast surgery and designed a prospective, randomised, placebo-controlled trial for pain management.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Erector spinae plane blockProcedure or surgery

    Ultrasound guided bilateral erector spinae plane block will be administered. An intravenous patient control analgesia device with morphine will be given to patients.

  • sham blockOther

    A sham block will be applied. Skin will be infiltrated with local anesthetics, and 2 mL subcutaneous saline injection will be applied.An intravenous patient control analgesia device with morphine will be given to patients.

Study groups in NCT03621345
Study groupRoleWhat they receive
ESP block groupActive comparatorThe bilateral erector spine plane (ESP) block will be performed with ultrasound guided, preoperatively. Following antiseptic preparation of block site with povidone iodine, ultrasound probe will be placed 3 cm lateral to spine at T5 level. After identifying the erector spinae muscle and transverse process, the overlying skin will be infiltrated with local anesthetics and 20 mL local anesthetics (10 mL 0.5% bupivacaine + 10 mL 1% lidocaine) will be injected deep to the erector spinae muscle. The same procedure will be performed on the other side. Also, patients will receive intravenous patient controlled analgesia with morphine, and 1 g acetaminophen for supplemental analgesia if pain score raises over 5/10 on NRS and 50 mg meperidine for rescue analgesic for persistent pain. Interventions: Procedure: Ultrasound guided erector spinae plane block Other: Standard Pain Followup and Monitorization
Receives: Procedure: Erector spinae plane block
sham blockSham comparatorA sham block will be performed while looking for intended location for ESP block placement. Skin will be infiltrated with local anesthetics but ESP block will not be performed, instead of ESP block 2 mL subcutaneous saline injection will be applied. Intervention: Sham block Other: Standard Pain Followup and Monitorization
Receives: Other: sham block

What is being measured

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

  1. Postoperative morphine consumption

    Morphine consumption in Patient Controlled Analgesia device

    Measured: 24 hours

Secondary outcomes (10)
  1. Intraoperative anesthetic consumption

    Intraoperative total doses of remifentanil, pentothal, desflurane consumption

    Measured: During operation time

  2. Extubation and recovery time

    Using modified aldrete score

    Measured: Through surgical operation completion

  3. Pain assessed by NRS

    Numeric rating scale (NRS) at rest and in motion will be recorded at intervals. NRS is a unidimensional measure of pain intensity in adults. The NRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").

    Measured: 24 hours

  4. Degree of sedation

    Ramsay Sedation Scale (RSS) will be used to assess degree of sedation. The RSS was designed as a test of arousability. The RSS scores sedation at six different levels, according to how arousable the patient is. The RSS defines the conscious state from a level 1: the patient is anxious, agitated or restless, through the continuum of sedation to a level 6: the patient is completely unresponsive.

    Measured: 24 hours

  5. Rate of opioid related side effects

    Opioid related side effects such as nause/vomiting, pruritis, bradycardia, hypotension will be evaluated at intervals up to 24 hours.

    Measured: 24 hours

  6. Supplemental and rescue analgesic requirement

    Total supplemental and rescue analgesic consumption

    Measured: 24 hours

  7. Patient satisfaction assessment

    It will be assessed with patient satisfaction scale classified as 'excellent': no pain, NRS=0; 'good': very mild pain, NRS=1-2; 'moderate': mild pain, NRS=3-4.

    Measured: At the postoperative 24th hour

  8. Bilateral shoulder mobility

    It will be assessed with ability of shoulder abduction degree

    Measured: Preoperative and postoperative 4th, 8th, 12th, and 24th hours

  9. Length of stay in hospital

    Duration of length of stay in hospital will be recorded

    Measured: Until discharge from hospital, up to 7 days postoperatively

  10. Rate of block related complications

    Rate of block related complications such as hematoma, nerve deficit, pneumothorax etc. will be recoded.

    Measured: Until discharge from hospital, up to 7 days postoperatively
