Acute postoperative opioid consumption trajectories and long-term outcomes in pediatric patients after spine surgery.
Background: The days following surgery are a critical period where the use of opioids predicts long-term outcomes in adults. It is currently unknown as to whether opioid consumption throughout the acute postoperative period is associated with long-term outcomes in pediatric patients. The aims of this study were to characterize opioid consumption trajectories in the acute postoperative period, identify predictors of trajectory membership and determine associations between opioid consumption trajectories and long-term patient outcomes. ⋯ Opioid consumption during the acute postoperative period was not significantly associated with pain, functional activity or pain medication use at 6 months after surgery. Conclusion: In pediatric patients, intraoperative intrathecal morphine dose predicts opioid consumption in the acute postoperative period. Importantly, opioid consumption during this period does not affect long-term outcomes in pediatric patients after a spine surgery.

Microvascular decompression and radiofrequency for the treatment of trigeminal neuralgia: a meta-analysis.
Surgical treatments are used for trigeminal neuralgia (TN) when drug treatment fails. Surgical options can be divided into two categories: ablation (destructive) or non-ablation. Microvascular decompression (MVD) is primarily a non-ablation option, while radiofrequency thermocoagulation/rhizotomy (RF) is an ablation option. The aim of this study was to compare outcomes of MVD versus RF in the treatment of TN. ⋯ MVD had a lower risk of requiring a secondary procedure and facial numbness after surgery. RF could be considered in patients who are unfit for MVD or refused invasive treatment.

Effects of low-dose ketamine infusion on remifentanil-induced acute opioid tolerance and the inflammatory response in patients undergoing orthognathic surgery.
Remifentanil is associated with acute opioid tolerance that can lead to increased postoperative consumption of opioid analgesics. The purpose of this study was to determine whether a low dose of ketamine prevents remifentanil-induced acute opioid tolerance and affects the neutrophil-lymphocyte ratio (NLR), a newly recognized biomarker of inflammation. ⋯ High-dose intraoperative remifentanil induced postoperative acute opioid tolerance that was prevented by infusion of low-dose ketamine. Ketamine increased the postoperative NLR associated with decreased fentanyl requirement for postoperative pain control.

Targeted Epidural Blood Patches Under Fluoroscopic Guidance For Incidental Durotomies Related To Spine Surgeries: A Case Series.
Incidental durotomies are usually managed conservatively. However, 1.8% of patients require surgical dural repair for CSF leak. There are limited data available regarding the use of epidural blood patches (EBP) for persistent CSF leaks secondary to incidental durotomies. This case series aims to evaluate the efficacy of targeted EBPs under fluoroscopic guidance in the treatment of incidental durotomies. ⋯ This case series demonstrated that targeted EBP can be an effective treatment for CSF leak from incidental durotomies. However, dural tears in the cervical region may be more difficult to treat. Larger scale studies are required to evaluate efficacy of EBP in the treatment of symptomatic incidental durotomies.

C7 slope and its association with serum lipid levels and Modic changes in patients with cervical spondylotic myelopathy.
Background: Several studies have substituted the T1 slope (T1S) with the C7 slope (C7S) because the C7 endplate is clearer on radiographs. Further, abnormal serum lipid levels have been proven to be related with the development of disc degeneration. The aim of this study was to explore the relationship between C7S, serum lipid levels, cervical parameters related to cervical sagittal balance and Modic changes (MCs) in patients with multisegment cervical spondylotic myelopathy (CSM). ⋯ The correlation between HDL-C, LDL-C, ALB, GLB, Ca2+, C7S, T1S, MCs, NT, TIA, and C2-C7 SVA was statistically significant. Conclusion: Significant correlations were observed between MCs and TG (as well as other preoperative sagittal parameters), which may accelerate the development of degeneration of the cervical spine. Therefore, alcohol consumption, TG, and sagittal parameters, such as C7S, and T1S could be a promising candidate for the assessment of cervical sagittal balance and predicting neck pain.
