These adverse events might be due to increased intracranial pressure (ICP), presumably induced by increased spinal intra-/epidural pressure caused by fluid irrigation. This study was designed to perform interlaminar endoscopic lumbar discectomy (IELD) at different irrigation fluid settings while monitoring its effect on intra-/epidural and ICPs, with and without dural tears.</p><p><strong>Methods: </strong>Spinal intradural pressures were measured by introducing catheters through a sacral approach to human cadavers' lumbar, thoracic, and cervical levels. Additionally, an epidural probe was placed at L3-4. ICP was measured by an intraventricular probe.

The complexity of spine procedures, coupled with patient variability, necessitates a multifaceted approach to pain control. Over time, numerous strategies have emerged, each with varying levels of effectiveness. Pharmacological approaches, including multimodal analgesia, local anesthetic infusions, and gabapentinoids, provide relief for both acute and chronic pain. Additionally, perioperative strategies such as enhanced recovery after surgery (ERAS) protocols have demonstrated benefits in optimizing pain control and recovery outcomes. Beyond pharmacological interventions, physical therapy has become a cornerstone of postoperative pain management, aiding in functional recovery and reducing reliance on medications. For patients with refractory or chronic pain, neuromodulatory techniques such as spinal cord stimulation and intrathecal injections offer alternative solutions. Despite the breadth of evidence-based strategies available, limitations persist, including opioid dependence, the complexity of multimodal regimens leading to suboptimal compliance, and cases of refractory pain. These challenges underscore the importance of tailoring pain management approaches to individual patient needs, ensuring a balance between effectiveness and safety.

Three guidelines did not include surgical treatments, and 2 guidelines did not include nonsurgical therapies. Recommendation criteria varied among guidelines due to differences in the intended audience. HLD can be treated with various modalities with specific therapies offering better pain relief.
