Background: Intrathecal baclofen pumps are commonly used for the management of lower extremity spasticity in the setting of spinal cord injury. There have been no reports of the performance of spinal anesthesia in patients with a pre-existing intrathecal baclofen pump.
Case Presentation: A 29-year-old parturient presented for cesarean section. She had a history of spinal cord injury due to fractures of the thoracic vertebrae with lower extremity spasticity, which had been treated with an intrathecal baclofen pump inserted through lumbar (L) 3-L4 intervertebral space. Preoperative lumbosacral ultrasound was performed to identify the L4-5 interspace, and spinal anesthesia was performed through that space with a 25-gauge 3.5-inch-long Whitacre spinal needle. Thoracic (T) 4 dermatomal level anesthesia was achieved, and the patient underwent the cesarean section without requiring additional intravenous analgesic adjuncts.
Conclusions: Spinal anesthesia can be successfully performed in patients with intrathecal baclofen pumps. Existing intrathecal catheters can be located with preoperative imaging, and ultrasound can be used to determine the vertebral levels below the intrathecal catheter through which spinal anesthesia can be performed safely.

Awake, endoscopic lumbar interbody spinal fusion: 10 years of experience with the first 400 cases.
J Neurosurg Spine
January 2025
2Anesthesiology, University of Miami Miller School of Medicine, Miami, Florida.
Objective: Awake, endoscopic spinal fusion has been utilized as an ultra-minimally invasive surgery technique to accomplish the goals of spinal fixation, fusion, and disc height restoration. While many techniques exist for this approach, this series represents a single institution's experience with a large cohort and the evolution of this method.
Methods: The medical records of a consecutive series of 400 patients treated over a 10-year period were retrospectively reviewed.
Spinal Anesthesia in Elderly Patients With Femoral Neck Fractures on Apixaban Therapy: A Case Series.
A A Pract
January 2025
From the Department of Anesthesiology, Sheba Medical Center, Ramat Gan, Israel.
This case series reviews surgeries involving elderly patients with femoral neck fractures on apixaban who underwent spinal anesthesia (SA) within 72 hours of their last dose. Despite patients being on anticoagulation, no neurological complications occurred, suggesting SA may be practical in cases where the benefits of timely surgery outweigh the potential risks, including apixaban discontinuation for a period of less than the recommended 72 hours with detectable levels of the drug remaining in the plasma. Quantitative apixaban measurements offered useful anticoagulation status insights, though safe thresholds remain undefined.

Urological malignancies during pregnancy are exceedingly rare, with bladder cancer posing significant diagnostic and management challenges. This study describes a 28-year-old pregnant woman diagnosed with non-invasive papillary urothelial carcinoma, presenting with painless hematuria at 22 weeks of gestation. The diagnostic process included ultrasound and MRI, both of which confirmed a solitary polypoidal lesion.

Objectives: Postoperative pain, nausea and vomiting adversely affect postoperative rehabilitation after total knee arthroplasty (TKA). We aimed to identify factors associated with postoperative pain trajectory and postoperative nausea and vomiting (PONV) and evaluated the effects of different analgesic modalities.
Methods: We retrospectively reviewed patients undergoing unilateral primary TKA from 2017 to 2022.
Analgesic Safety and Efficacy of Peri-Operative Posterior Cervical Muscle Plane Blocks in Elective Posterior Cervical Spine Surgery: A Systematic Review with Meta-Analyses.
Clin J Pain

Department of Neurosurgery, University of Nebraska Medical Center. Omaha, Nebraska.
Objective: Posterior cervical spine surgery can result in significant discomfort in the post-operative period. Post-operative pain management presents a challenge, particularly in the elderly population which is more sensitive to adverse effects from analgesia. We aimed to compare outcomes after peri-operative posterior cervical muscle plane blocks versus patients who received general anesthesia only.
