This prospective study aimed to compare the efficacy of epidural (EDA) versus intravenous (PCA) application of analgesics after lumbar fusion. Fifty-two patients scheduled for elective posterior instrumented lumbar fusion were randomized into two groups. EDA patients received an epidural catheter intraoperatively, and administration of ropivacain and sulfentanil was started after a normal post-operative wake-up test in the recovery room area. PCA patients received intravenous opioids in the post-operative period. Differences between EDA and PCA groups in terms of patient satisfaction with respect to pain relief were not significant. Nevertheless, EDA patients reported less pain on the third day after surgery. There were significantly more side effects in the EDA group, including complete reversible loss of sensory function and motor weakness. There were no major side effects, such as infection or persisting neurological deficits, in either group. The routine use of epidural anesthesia for lumbar spine surgery has too many risks and offers very little advantage over PCA.

Abstract BACKGROUND Despite the potential for faster postoperative recovery and the ease of direct intraoperative injection, intrathecal morphine is rarely provided in lumbar spine surgery. OBJECTIVE To evaluate the safety and efficacy of intrathecal morphine following lumbar fusion. METHODS We randomly assigned 150 patients undergoing elective instrumented lumbar fusion to receive a single intrathecal injection of morphine (0.2 mg) or placebo (normal saline) immediately prior to wound closure. The primary outcome was pain on the visual-analogue scale during the first 24 h after surgery. Secondary outcomes included respiratory depression, treatment-related side effects, postoperative opioid requirements, and length of hospital stay. An intention-to-treat, repeated-measures analysis was used to estimate outcomes according to treatment in the primary analysis. RESULTS The baseline characteristics of the 2 groups were similar. Intrathecal morphine reduced pain both at rest (32% area under the curves [AUCs] difference, P < .01) and with movement (22% AUCs difference, P < .02) during the initial 24 h after surgery. The risk of respiratory depression was not increased by intrathecal morphine (hazard ratio, 0.86; 95% confidence interval, 0.44 to 1.68; P = .66). Although postoperative opioid requirements were reduced with intrathecal morphine (P < .03), lengths of hospital stay were similar (P = .32). Other than a trend towards increased intermittent catheterization among patients assigned to intrathecal morphine (P = .09), treatment-related side effects did not significantly differ. The early benefits of intrathecal morphine on postoperative pain were no longer apparent after 48 h. CONCLUSION A single intrathecal injection of 0.2 mg of morphine safely reduces postoperative pain following lumbar fusion.

Abstract The incidence of cervical and lumbar fusion surgery has increased in the past twenty years, and during follow-up some of these patients develop changes at the adjacent segment. Recognizing that adjacent segment degeneration and disease may occur in the future does not alter the rating for a cervical or lumbar fusion at the time the patient's condition is determined to be at maximum medical improvement (MMI). The term adjacent segment degeneration refers to the presence of radiographic findings of degenerative disc disease, including disc space narrowing, instability, and so on at the motion segment above or below a cervical or lumbar fusion. Adjacent segment disease refers to the development of new clinical symptoms that correspond to these changes on imaging. The biomechanics of adjacent segment degeneration have been studied, and, although the exact mechanism is uncertain, genetics may play a role. Findings associated with adjacent segment degeneration include degeneration of the facet joints with hypertrophy and thickening of the ligamentum flavum, disc space collapse, and translation—but the clinical significance of these radiographic degenerative changes remains unclear, particularly in light of the known presence of abnormal findings in asymptomatic patients. Evaluators should not rate an individual in anticipation of the development of changes at the level above a fusion, although such a development is a recognized possibility.

Study Design: Uncontrolled retrospective observational study. Objectives: Surgery for patients with back pain and degenerative disc disease is controversial, and studies to date have yielded conflicting results. We evaluated the effects of lumbar fusion surgery for patients with this indication in the Canadian Spine Outcomes and Research Network (CSORN). Methods: We analyzed data that were prospectively collected from consecutive patients at 11 centers between 2015 and 2019. Our primary outcome was change in patient-reported back pain at 12 months of follow-up, and our secondary outcomes were satisfaction, disability, health-related quality of life, and rates of adverse events. Results: Among 84 patients, we observed a statistically significant improvement of back pain at 12 months that exceeded the threshold of Minimum Clinically Important Difference (MCID) (mean change -3.7 points, SD 2.6, p < 0.001, MCID = 1.2; 77% achieved MCID), and 81% reported being “somewhat” or “extremely” satisfied. We also observed improvements of Oswestry Disability Index (-17.3, SD 16.6), Short Form-12 Physical Component Summary (10.3, SD 9.6) and Short Form-12 Mental Component Summary (3.1, SD 8.3); all p < 0.001). The overall rate of adverse events was 19%. Conclusions: Among a highly selective group of patients undergoing lumbar fusion surgery for degenerative disc disease, most experienced a clinically significant improvement of back pain as well as significant improvements of disability and health-related quality of life, with high satisfaction at 1 year of follow-up. These findings suggest that surgery for this indication may provide some benefit, and that further research is warranted.

Abstract OBJECTIVE Hyperperfusion syndrome is a rare and potentially devastating complication of carotid endarterectomy or carotid artery angioplasty and stenting. With the advent of new imaging techniques, we reviewed our experience with this phenomenon. METHODS This report is a retrospective review of 129 consecutive cases of carotid endarterectomy performed between June 1, 2000, and May 31, 2002, and 44 consecutive cases of carotid artery angioplasty and stenting performed between January 1, 1997, and May 31, 2002. We specifically searched for examples of patients who developed postprocedural nonthrombotic neurological deficits that typified the hyperperfusion syndrome. RESULTS Seven cases of hyperperfusion syndrome occurred, four after endarterectomy (3.1% of carotid endarterectomy cases) and three after stenting (6.8% of stenting cases). The cases of hyperperfusion were classified as presenting with 1) acute focal edema (two cases with stroke-like presentation, attributable to edema immediately after revascularization), 2) acute hemorrhage (two cases of intracerebral hemorrhage immediately after stenting and one case immediately after endarterectomy), or 3) delayed classic presentation (two cases with seizures, focal motor weakness, and/or late intracerebral hemorrhage at least 24 hours after endarterectomy). CONCLUSION Hyperperfusion syndrome may be more common and more variable in clinical presentation than previously appreciated.

Stewardship Program

OBJECTIVE Opioid stewardship programs combine clinical, regulatory, and educational interventions to minimize inappropriate opioid use and prescribing for orthopedic and spine surgery. Most evaluations of stewardship programs quantify effects on prescriber behavior, whereas patient-relevant outcomes have been relatively neglected. The authors evaluated the impact of an opioid stewardship program on perioperative opioid consumption, prescribing, and related clinical outcomes after multilevel lumbar fusion. METHODS The study was based on a retrospective, quasi-experimental, pretest-posttest design in 268 adult patients who underwent multilevel lumbar fusion in 2016 (preimplementation, n = 141) or 2019 (postimplementation, n = 127). The primary outcome was in-hospital opioid consumption (morphine equivalent dose [MED], mg). Secondary outcomes included numeric rating scale pain scores (0–10), length of stay (LOS), incidence of opioid-induced side effects (gastrointestinal, nausea/vomiting, respiratory, sedation, cognitive), and preoperative and discharge prescribing. Outcomes were measured continuously during the hospital admission. Differences in outcomes between the epochs were assessed in bivariable (Wilcoxon signed-rank or Fisher’s exact tests) and multivariable (Wald’s chi-square test) analyses. RESULTS In bivariable analyses, there were significant decreases in preoperative opioid use (46% vs 28% of patients, p = 0.002), preoperative opioid prescribing (MED 30 mg [IQR 20–60 mg] vs 20 mg [IQR 11–39 mg], p = 0.003), in-hospital opioid consumption (MED 329 mg [IQR 188–575 mg] vs 199 mg [100–372 mg], p < 0.001), the incidence of any opioid-related side effect (62% vs 50%, p = 0.03), and discharge opioid prescribing (MED 90 mg [IQR 60–135 mg] vs 60 mg [IQR 45–80 mg], p < 0.0001) between 2016 and 2019. There were no significant differences in postanesthesia care unit pain scores (4 [IQR 3–6] vs 5 [IQR 3–6], p = 0.33), nursing floor pain scores (4 [IQR 3–5] vs 4 [IQR 3–5], p = 0.93), or total LOS (118 hours [IQR 81–173 hours] vs 103 hours [IQR 81–132 hours], p = 0.21). On multivariable analysis, the opioid stewardship program was significantly associated with decreased discharge prescribing (Wald’s chi square = 9.45, effect size −52.4, 95% confidence interval [CI] −86 to −19.0, p = 0.002). The number of lumbar levels fused had the strongest effect on total opioid consumption during the hospital stay (Wald’s chi square = 16.53, effect size = 539, 95% CI 279.1 to 799, p < 0.001), followed by preoperative opioid use (Wald’s chi square = 44.04, effect size = 5, 95% CI 4 to 7, p < 0.001). CONCLUSIONS A significant decrease in perioperative opioid prescribing, consumption, and opioid-related side effects was found after implementation of an opioid stewardship program. These gains were achieved without adverse effects on pain scores or LOS. These results suggest the major impact of opioid stewardship programs for spine surgery may be on changing prescriber behavior.

Fetal Oxygenation

Introduction: Labour pain is among the most severe pain a woman can experience in her lifetime. Painful labour has decrimental effects on both mother and fetus leads to severe physical and psychological stress. Maternal hyperventilation in response to pain reduces fetal oxygenation and hypoventilation between contractions combined with decreased blood ow worsens fetal hypoxemia. It has been suggested that conning women to bed during labour may cause the labour to be longer and more painful with increase in abnormal presentation, instrumental deliveries and fetal distress. Aims And Objectives:The onset, quality and duration of their analgesic action. Incidence of unwanted effects like muscle weakness, hypotension, pruritus, nausea/vomiting, fetal bradycardia by the individual drugs. Materials And Methods: The study was conducted in the department of anesthesia, Darbhanga Medical College & Hospital, Laheriasarai, Bihar. Methods of collection of data (including sampling procedure if any) : After institutional committee approval and written informed consent from parturients and their relatives for the procedure the study was conducted and data were collected. Results: Duration of analgesia was found varying widely. It was 55±12.34 minutes in Group I whereas 75 ±14.36 minutes in Group II. The incidence of pruritus almost mild or negligible in both groups. The incidence of motor weakness in group II was 24 (80%) whereas in group I it was 10(33%). There was signicant statistics difference in motor weakness between two groups (p< 0.001) by Chi square test 9 with yate's correction. Other side effects differences between two groups were not statistically signicant. Summary And Conclusion:Both the drugs provided excellent quality of analgesia to the parturient in pain. The difference in duration of analgesia was signicant between the two groups statistically. Mean duration of analgesia lasted for 55 minutes in group I whereas in group II, it lasted for 75 minutes. Main side effects encountered in this study were motor weakness of longer duration in group II than in group I. Other side effects like nausea-vomiting were comparable to each other and were minimal in nature.

Cognitive Improvement

Intellectual disability is the most prevalent and limiting hallmark of Down syndrome (DS), without any pharmacological treatment available. Neurodegeneration and neuroinflammation are relevant neurological features of DS reaching to early development of Alzheimer s disease. Preclinical evidence suggests that the endocannabinoid system, an important neuromodulator on cognition and neuroinflammation, could act as beneficial target in DS. Indeed, cannabinoid type-1 receptor (CB1R) activity was enhanced in the hippocampus of young-adult trisomic Ts65Dn mice, a well-characterized surrogate model of DS. In previous studies, inhibition of CB1R, was able to restore key neurological deficits in this mouse model. To determine the possible clinical relevance of this target, it is mandatory to evaluate the long-term consequences of attenuated CB1R activity and to minimize the possible side-effects associated to this mechanism. We found that CB1R expression was significantly enhanced in the hippocampus brains of aged DS subjects. Similarly, middle-aged trisomic mice showed enhanced CB1R expression. Long-term oral administration of a low dose of the CB1R specific antagonist rimonabant was administered to male and female Ts65Dn trisomic and wild-type mice from the time of weaning to 10 months, an age when signs of neurodegeneration have been described in the model. CB1R inhibition resulted in significant cognitive improvement in novel object-recognition memory in trisomic male and female mice, reaching a similar performance to that of wild-type littermates. Interestingly, this long-term rimonabant treatment modify locomotor activity, anxiety-like behavior, body weight or survival rates. Brain analysis at 10 months of age revealed noradrenergic and cholinergic neurodegeneration signs in trisomic mice that were not modified by the treatment, although the alterations in hippocampal microglia morphology shown by vehicle-treated trisomic mice was normalized in trisomic mice exposed to rimonabant. Altogether, our results demonstrate a sustained pro-cognitive effect of CB1R inhibition at doses that do not produce major side effects that could be associated to an anti-inflammatory action, suggesting a potential interest in this target of to preserve cognitive functionality in DS.
