Study summary

COMPARISON OF THE EFFECTS OF ERECTOR SPINAE PLANE (ESP) BLOCK AND QUADRO İLİAC PLANE (QIP) BLOCK ON POSTOPERATIVE OPIOID CONSUMPTION AND PAIN IN LUMBAR SPINAL SURGERY

Read the detailed description

The study is designed as a double-blind, prospective, randomized controlled trial. Regarding blinding, the healthcare personnel responsible for monitoring postoperative pain will be unaware of whether the patients received an ESP block or a QIP block. Patient randomization was planned using a computer-based system. Following the operation, once patients are transferred to the postoperative recovery room, their pain levels will be assessed and recorded using the Numeric Rating Scale (NRS) at the following time points: 30 minutes, and 1, 6, 12, and 24 hours. In the ward, patients will receive tramadol via PCA and paracetamol every eight hours. Hourly NRS monitoring is planned during the patient's follow-up in the ward. If the NRS score reaches 4 or higher during this period, 75 mg of diclofenac sodium will be administered intramuscularly, and the number of self-administered bolus doses via PCA (Patient-Controlled Analgesia) within the first 24 hours will be recorded. Opioid consumption and pain levels (via NRS scores) will be evaluated at the 24th postoperative hour for patients in both the ESP and QIP block groups. Additionally, the patients' hemodynamic parameters will be recorded at these time intervals.

Interventions

  • Diagnostic testNRS Score

    An 11-point Numerical Rating Scale (NRS), where 0 indicated no pain and 10 represented the worst pain imaginable, was used to assess patients' pain levels.

  • Diagnostic testtotal tramadol consumption

    The total number of patient-controlled analgesia (PCA) bolus doses delivered within the first 24 hours will record

  • DrugPost Operative Pain Relievers

    All patients in the ward will be administered intravenous paracetamol every 8 hours, and intramuscular diclofenac sodium (75 mg) if the NRS score is 4 or higher.

What researchers measure

Primary outcomes

  1. To compare the effects of the Quadro İliac Plane Block and the Erector Spinae Plane (ESP) Block on postoperative opioid consumption in lumbar spinal surgeries

    All patients will be administered tramadol via PCA, and the amount of tramadol consumed will be assessed at the end of the 24-hour postoperative period.

    Time frame: 24 hour

Secondary outcomes

  1. To compare the effects of the Quadro iliac (Qıp) block and the Erector Spinae Plane (ESP) block on postoperative pain in lumbar spinal surgeries

    The NRS score will be assessed on a scale of 0 to 10, with 0 representing the lowest and 10 the highest value; patients will be asked to provide a rating at the 12th hour.

    Time frame: 12th hour
