About this study

Official title: Investigation of Erector Spinae Plane Block Effect in Spine Surgery

Spine surgery is typically associated with severe postoperative pain. Although the number of spine surgeries has increased day by day, postoperative pain management have been limited. The recently described erector spinae plane block (ESPB) is obtained by applying the local anesthetic drug between the fascia of the erector spinae muscles and the transverse process of the vertebrae. Anatomical and radiological investigations in fresh cadavers suggest that the potential place of influence of ESPB is dorsal and ventral spinal nerve roots. A small number of publications showing the analgesic efficacy of ESP in spinal surgery have been reported in the literature. The erector spinae muscles are easily identified during spine surgery, and erector spinae plane blocks can be performed under direct vision rather than via ultrasound guidance or simply using anatomical landmarks. Therefore, the investigators aim to observe the efficacy of the under direct vision erector spinae plane block on pain scores after spinal surgery.

Read the detailed description

Approval from the university local ethics committee will be obtained. Participans will be informed about the potential benefits and complications after the study protocol has been fully and thoroughly explained. After premedication with 0.03 mg / kg iv midazolam, participans will be noninvasively monitored by taking into the operating room (heart rate, blood pressure, pulse oximetry). Anesthesia induction will delivered with fentanyl 1mcg / kg, propofol 2 mg / kg and rocuronium 0.6 mg / kg. The maintenance of anesthesia will be achieved by infusion of sevoflurane 2-3% in 50% O2/50% medical air and remifentanil infusion of 0.1-0.5 mcg / kg / min. Thirty minutes before end of the surgery, all patients were intravenously administered 1 mg/kg tramadol HCl and 1gr paracetamol.

Under direct vision ESPB technique: Erector spinae muscles and transverse processes will be identified by the surgeon. At the end of the surgery 20 ml bupivacaine 0.25%/lidocaine 1% mixture will be injected to the between of the erector spinae muscles and transverse processes bilaterally. In the sham comparator group, 20 ml of isotonic saline will be administered bilaterally by the surgeon as described above.

After the surgery, 1 g paracetamol was intravenously administered once every 8 h. A patient-controlled analgesia (PCA) device, which was prepared using morphine, was attached to the patients and was programmed to administer concentration 0.5mg / ml ( 2cc bolus 8 min lock time 2cc/h infusion). This administration continued for 24 h. Postoperative pain was assessed using visuel analog scale (VAS) (VAS 0 = no pain, VAS 10 = most severe pain ). Duration at postanesthesia care unit (PACU) was recorded right from 0 h. VAS scores at 0, 1, 6, 12 and 24 h were recorded. Postoperative nausea and vomiting (PONV) was evaluated using a numeric ranking scale (0 = no PONV, 1 = mild nausea, 2 = severe nausea or vomiting once attack, and 3 = vomiting more than once attack). If PONV score was >2, the antiemetic metoclopramide Hcl 10mg was intravenously administered.

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

    Also called ESP block

    Bilateral 20 ml Bupivacaine 0.25% + lidocaine 1% injected between erector spinae muscles and transverse process under direct vision.

  • Control groupProcedure or surgery

    Also called Sham comparator

    20 ml NaCl 0,9% used for the infiltration between the transverse process and the erector spinal muscle under direct vision on each side.

What is being measured

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

  1. Total morphine consumption

    The total amount of morphine given by patient controlled analgesia in 24 hours will be recorded

    Measured: 1 day

Secondary outcomes (2)
  1. Pain intensity score

    Changes in Numeric Rating Scale (NRS) will be recorded at postoperative 1, 6, 12, 24 hour. 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 patient pain. Each item is scored 0-10( 0:no pain 10: pain as bad as can be )

    Measured: 1 day

  2. Postoperative nausea and vomiting

    Changes in Numeric Rank Score will be recorded at postoperative 1, 6, 12, 24 hour. Numeric rank score 0-3(0: no nausea and vomiting; 1:have nausea, no vomiting; 2:once vomiting attack; 3: have two or more vomiting attacks)

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing Erector spinae plane block in people with Acute Pain, run by Bezmialem Vakif University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total morphine consumption (time frame: 1 day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2021.
