Meta Analysis
Effectiveness of Lateral Decubitus Position for Preventing Post-Dural Puncture Headache: A Meta-Analysis.
Post-dural puncture headache (PDPH) is a relatively common complication of lumbar punctures for spinal anesthesia or neurologic diagnosis. For many years, a high number of drugs has been evaluated to treat PDPH, yet there is a minority to prevent this complication. The lateral decubitus position instead of sitting position during lumbar puncture has become an interesting approach because of its feasibility and patient satisfaction. ⋯ Our results indicate that lateral decubitus position during lumbar puncture seems to be a good alternative for preventing PDPH. Further research should focus on the new prophylactic alternatives to reduce the incidence of PDPH.

Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) have sufficient scientific support for their use as tissue protectors. Preliminary studies suggest that their angiotensin-II type 2 receptor (AT2R)-blocking properties have a beneficial profile in the treatment of neuropathic pain. ⋯ AT2R inhibitors might offer partial and selective neuroprotective qualities of the myelinated fibers A-beta; and A-delta in cancer patients who receive neurotoxic chemotherapy.

Patients with implanted spinal cord stimulators (SCS) present to the anesthesia care team for management at many different points along the care continuum. Currently, the literature is sparse on the perioperative management. What is available is confusing; monopolar electrocautery is contraindicated but often used, full body magnetic resonance imaging (MRI) is safe with particular systems but with other manufactures only head and specific extremities exams are safe. Moreover, there are anesthetizing locations outside of the operating room where implanted SCS can interact with surrounding medical equipment and pose significant risk to patient and device. ⋯ SCS is being used earlier in the treatment algorithm for patients with chronic pain. The anesthesia care team needs working knowledge of where the device resides in the neuraxial space and what risks different medical technologies pose to the patient and device. This understanding will lead to appropriate perioperative management which can reduce risk and improve patient outcomes.

Cost utility or cost effective analysis continues to take center stage in the United States for defining and measuring the value of treatments in interventional pain management. Appropriate cost utility analysis has been performed for caudal epidural injections, percutaneous adhesiolysis, and spinal cord stimulation. However, the literature pertaining to lumbar interlaminar epidural injections is lacking, specifically in reference to cost utility analysis derived from randomized controlled trials (RCTs) with a pragmatic approach in a practical setting. ⋯ This cost utility analysis of lumbar interlaminar epidural injections in patients nonresponsive to conservative management in the treatment of disc herniation, central spinal stenosis, and axial or discogenic low back pain in the lumbar spine shows the clinical effectiveness and cost utility of these injections of $1,976.58 for direct costs with a total cost of $3,301 per QALY.

Percutaneous full-endoscopic discectomy (PED) is being increasingly used because of its potential to minimalize soft-tissue damage and decrease hospital stay. PED using the interlaminar approach (PED-IL) at L4-L5 is performed by only a few surgeons. To the best of our knowledge, the safety and efficacy of PED-IL at L4-L5, without experience in PED via a transforaminal approach (PED-TF) has not been previously reported. ⋯ The clinical outcomes of PED-IL at L4-L5 were equal to those at L5-S1. Therefore, PED-IL is suitable to be a standard method for any type of intracanalicular disc herniation.
