Brief Summary

Lumbar discectomy surgeries are often the last option for patients with disc herniation who do not improve with conservative treatments. However, these procedures can lead to significant perioperative pain that may become chronic without effective management. While intravenous opioids are commonly used for pain control, they can complicate recovery and pose risks like dependence. In contrast, regional anesthetic techniques offer advantages such as quicker recovery, better postoperative pain relief, and reduced opioid use, which can lead to shorter hospital stays. Our study aims to compare the effectiveness of the retrolaminar block with local wound infiltration for pain management following posterior lumbar discectomy surgeries, potentially improving patient outcomes.

Outcome Measures

Primary Outcomes (2)

  • Number of patients who required rescue analgesia

    The percentage of patients who required rescue analgesia within the first 24 hours.

    The first 24 hours postoperative.

  • Total amount of opioid consumption

    The total opioid consumption within the first 24 hours postoperative.

    The first 24 hours postoperative.

Secondary Outcomes (3)

  • The Numerical Pain Rating Scale

    The first 24 hours postoperative.

  • Duration of the surgical intervention.

    The first 2 hours.

  • Patient satisfaction (quality of life questionnaire)

    At the end of the first 24 hours postoperative.

Study Arms (2)

Retrolaminar block group

ACTIVE COMPARATOR

After confirming the correct position using imaging with a C-Arm device, the patient will receive a retrolaminar block on both sides at the level of the operated disc.

Procedure: Retrolaminar plane block

Local Infiltration group

ACTIVE COMPARATOR

The patient will receive local wound infiltration following the completion of the surgical steps with the patient in the prone position using a local anesthetic solution, tailored to the specific conditions surrounding the incision site.

Procedure: Local wound infiltration

Interventions

Retrolaminar plane infiltration with the local anesthetic mixture.

Retrolaminar block group

Local infiltration along the surgical incision.

Local Infiltration group
