Autonomic dysreflexia in spinal cord injury

Breastfeeding After Spinal Cord Injury: A Systematic Review of Prevalence and Associated Complications

Background

Breastfeeding can be a vital component for maternal and infant health, but successful breastfeeding may be especially difficult for mothers with spinal cord injury (SCI). No reliable research on prevalence or complications associated with breastfeeding for mothers with SCI currently exists.

Methods

Our systematic review aimed to answer the following: (1) What are the breastfeeding rates in women after SCI? (2) What are the rates and nature of postpartum complications reported by women with SCI in conjunction with breastfeeding?

Results

Ten studies were included; the reported rates at which women with SCI were able to breastfeed varied widely, ranging from 11% to 100%. Generally speaking, women with higher-level SCI (above T6) were less likely to breastfeed and would breastfeed less frequently than women with lower-level SCI and less frequently than women without SCI. Complications reported included problems with the let-down reflex, autonomic dysreflexia, and a higher incidence of postpartum depression in women with SCI.

Conclusion

More research on mothers with SCI is needed, especially matched-control research comparing mothers with and without SCI on successful breastfeeding and associated complications.

On-Line Survey About Autonomic Dysreflexia in Individuals with Spinal Cord Injury in Croatia

Background/Objectives: Autonomic dysreflexia (AD) is a clinical syndrome affecting persons with spinal cord injury (SCI). The aim of the study was to present the experience of individuals with SCI and AD in Croatia. Single-center questionnaire study. Setting: Faculty of Medicine, University of Rijeka, Rijeka, Croatia. Persons with SCI were divided into those with an SCI at T6 and above (n = 41) and those with an SCI at T7 and below (n = 29). Based on anamnestic data, patients with an SCI at T6 and above were further divided into those with and without self-reported clinical symptoms of AD (respectively: n = 33 and n = 8). Methods: The online survey included 23 questions of various types. It consisted of a general (demographic) section, section with specific questions about AD, and a section on self-assessment and quality of life. Based on the answers, the experience and knowledge of AD among individuals with an SCI in Croatia was assessed. Results: A total of 70 individuals with an SCI completed the whole survey. The average age was 40.6 years. The patients were predominantly male (72.9%) and mostly with a traumatic SCI (84.3%). Of the 70 individuals with an SCI, 35 (50%) reported they were familiar with AD, with the majority indicating that the internet was their primary source of information. Among those with an SCI who were unaware of AD, most (34/35 = 97.1%) wanted to learn about AD. The self-assessed quality of life was insignificantly better in patients with an SCI below T6 than in those with higher lesions. Patients with AD reported different symptoms and the most frequently reported symptom was a headache (70%). In 64% of participants, the primary trigger of AD were issues with the urinary bladder. In most individuals (55%), symptoms were not recognized by the healthcare providers. The individuals with AD were dissatisfied with the information about AD they received from doctors or nurses. Overall, 61% of all participants with AD rated their quality of life as good. Conclusions: Persons with an SCI are not adequately informed about AD. In most persons with AD, their symptoms are not properly recognized by healthcare providers. Our results suggest the need for more education of healthcare professionals about AD.

Feasibility and safety of two weeks of blood flow restriction exercise in individuals with spinal cord injury

CONTEXT

Reduced muscle strength and function are common after spinal cord injury (SCI). While low-load blood flow restriction exercise (BFRE) enhances muscle strength in healthy and clinical populations, its safety and feasibility in individuals with SCI remain underexplored.

OBJECTIVES

To investigate the feasibility and safety of low-load BFRE in individuals with incomplete SCI.

STUDY DESIGN

Case series.

SETTING

SCI rehabilitation center.

PARTICIPANTS

Six participants with motor incomplete SCI were enrolled in the study.

INTERVENTION

A two-week BFRE intervention for the lower limbs was conducted twice weekly at 40% total arterial occlusion pressure, using 30-40% of 1-repetition maximum loads.

OUTCOME MEASURES

Feasibility measures, specifically recruitment and eligibility rates and intervention acceptability, were collected. Blood pressure (BP) responses and specific coagulation markers for deep vein thrombosis (DVT) were assessed as safety measures.

RESULTS

Recruitment and eligibility rates were 2.8% and 6.6% for individuals admitted for first-time rehabilitation (subacute SCI) and 8.3% and 13.9% for 4-week readmission rehabilitation stays (chronic SCI), respectively. Intervention acceptability was high, characterized by 95.8% training adherence and low-to-moderate self-reported pain levels. BP responses and changes in C-reactive protein, Fibrinogen, and D-dimer during the intervention remained within clinically acceptable levels.

CONCLUSION

BFRE was feasible in an SCI rehabilitation setting despite a low recruitment rate. BFRE imposed no heightened risk of DVT or severe BP fluctuations in the present case series. Additionally, no severe adverse events occurred, and only mild complaints were reported. More extensive safety considerations warrant larger-scale exploration.

Management of acute cervical spinal cord injury in the non-specialist intensive care unit: a narrative review of current evidence

Each year approximately one million people suffer spinal cord injury, which has significant physical, psychosocial and economic impacts on patients and their families. Spinal cord rehabilitation centres are a well-established part of the care pathway for patients with spinal cord injury and facilitate improvements in functional independence and reductions in healthcare costs. Within the UK, however, there are a limited number of spinal cord injury centres, which delays admission. Patients and their families often perceive that they are not receiving specialist care while being treated in non-specialist units. This review aimed to provide clinicians who work in non-specialist spinal injury centres with a summary of contemporary studies relevant to the critical care management of patients with cervical spinal cord injury. We undertook a targeted literature review including guidelines, systematic reviews, meta-analyses, clinical trials and randomised controlled trials published in English between 1 June 2017 and 1 June 2023. Studies involving key clinical management strategies published before this time, but which have not been updated or repeated, were also included. We then summarised the key management themes: acute critical care management approaches (including ventilation strategies, blood pressure management and tracheostomy insertion); respiratory weaning techniques; management of pain and autonomic dysreflexia; and rehabilitation.

Pediatric Spinal Cord Injury: A Review

A spinal cord injury (SCI) can be a devastating condition in children, with profound implications for their overall health and quality of life. In this review, we aim to provide a concise overview of the key aspects associated with SCIs in the pediatric population. Firstly, we discuss the etiology and epidemiology of SCIs in children, highlighting the diverse range of causes. We explore the unique anatomical and physiological characteristics of the developing spinal cord that contribute to the specific challenges faced by pediatric patients. Next, we delve into the clinical presentation and diagnostic methods, emphasizing the importance of prompt and accurate diagnosis to facilitate appropriate interventions. Furthermore, we approach the multidisciplinary management of pediatric SCIs, encompassing acute medical care, surgical interventions, and ongoing supportive therapies. Finally, we explore emerging research as well as innovative therapies in the field, and we emphasize the need for continued advancements in understanding and treating SCIs in children to improve their functional independence and overall quality of life.

A comprehensive look at the psychoneuroimmunoendocrinology of spinal cord injury and its progression: mechanisms and clinical opportunities

Spinal cord injury (SCI) is a devastating and disabling medical condition generally caused by a traumatic event (primary injury). This initial trauma is accompanied by a set of biological mechanisms directed to ameliorate neural damage but also exacerbate initial damage (secondary injury). The alterations that occur in the spinal cord have not only local but also systemic consequences and virtually all organs and tissues of the body incur important changes after SCI, explaining the progression and detrimental consequences related to this condition. Psychoneuroimmunoendocrinology (PNIE) is a growing area of research aiming to integrate and explore the interactions among the different systems that compose the human organism, considering the mind and the body as a whole. The initial traumatic event and the consequent neurological disruption trigger immune, endocrine, and multisystem dysfunction, which in turn affect the patient's psyche and well-being. In the present review, we will explore the most important local and systemic consequences of SCI from a PNIE perspective, defining the changes occurring in each system and how all these mechanisms are interconnected. Finally, potential clinical approaches derived from this knowledge will also be collectively presented with the aim to develop integrative therapies to maximize the clinical management of these patients.

Simulation- vs. Didactic-Based Learning for Rehabilitation Nurses Caring for Patients With Autonomic Dysreflexia

PURPOSE

Autonomic dysreflexia (AD) is associated with spinal cord injury, manifesting in symptoms of high blood pressure, bradycardia, headache, diaphoresis, and anxiety. Nurses often manage these symptoms; thus, nursing knowledge of AD is crucial. The purpose of this study was to improve AD nursing knowledge while exploring differences between simulation and didactic learning in nurse education.

DESIGN AND METHODS

This prospective pilot study used two types of learning (simulation vs. didactic) to determine if one was superior to the other regarding nursing knowledge of AD. Nurses were given a pretest, randomized to simulation or didactic learning, and then given a posttest 3 months later.

RESULTS

Thirty nurses were enrolled in this study. Seventy-seven percent of nurses held a BSN degree with an average of 15.75 years in nursing. The mean knowledge scores for AD at baseline for the control (13.9 [2.4]) and intervention (15.5 [2.9]) groups were not statistically different ( p = .1118). The mean knowledge scores for AD after either didactic- or simulation-based education for the control (15.5 [4.4]) and intervention (16.5 [3.4]) groups were not statistically different ( p = .5204).

CLINICAL RELEVANCE

Autonomic dysreflexia is a critical clinical diagnosis that requires prompt nursing intervention to prevent threatening consequences. This study focused on how different methods of education best benefited AD knowledge acquisition and how simulation versus didactic learning impacts overall nursing education.

CONCLUSIONS

As a whole, providing nurses with AD education was helpful in improving their understanding of the syndrome. However, our data suggest that both didactic and simulation are equally effective methods to increase AD knowledge.

No pain, no strain: Targin® mitigates pain and constipation following spinal cord injury

BACKGROUND

Opioids effectively reduce chronic pain, but present significant side effects including opioid-induced constipation. Oxycodone/naloxone decreases pain and constipation in cancer patients, however its effect on spinal cord injury population remains understudied.

METHODS

We assessed whether oxycodone/naloxone reduces pain, constipation, and severity of autonomic dysreflexia in an individual with spinal cord injury. A 55-year-old male with C5 lesion presented with chief complaint of chronic pain received 5/2.5 mg and 20/10 mg oxycodone/naloxone for 6 and 2 weeks, respectively.

RESULTS

Oxycodone/naloxone improved pain, bowel function, and autonomic dysreflexia severity.

INTERPRETATION

Oxycodone/naloxone was effective in managing chronic pain and constipation in the studied case.

Charcot Arthropathy of the Spine

Charcot arthropathy of the spine (CSA), also known as spinal neuroarthropathy, is a progressive disease process in which the biomechanical elements of stability of the spine are compromised because of the loss of neuroprotection leading to joint destruction, deformity, and pain. Initially thought to be associated with infectious causes such as syphilis; however in the latter part of the century, Charcot arthropathy of the spine has become associated with traumatic spinal cord injury. Clinical diagnosis is challenging because of the delayed presentation of symptoms and concurrent differential diagnosis. Although radiological features can assist with diagnosis, the need for recognition and associated treatment is vital to limit the lifelong disability with the disease. The goals of treatment are to limit symptoms and provide spinal stabilization. Surgical treatment of these patients can be demanding, and alternative techniques of instrumentation are often required.

Psychosocial aspects of sports medicine in pediatric athletes: Current concepts in the 21st century

Behavioral aspects of organized sports activity for pediatric athletes are considered in a world consumed with winning at all costs. In the first part of this treatise, we deal with a number of themes faced by our children in their sports play. These concepts include the lure of sports, sports attrition, the mental health of pediatric athletes (i.e., effects of stress, anxiety, depression, suicide in athletes, ADHD and stimulants, coping with injuries, drug use, and eating disorders), violence in sports (i.e., concepts of the abused athlete including sexual abuse), dealing with supervisors (i.e., coaches, parents), peers, the talented athlete, early sports specialization and sports clubs. In the second part of this discussion, we cover ergolytic agents consumed by young athletes in attempts to win at all costs. Sports doping agents covered include anabolic steroids (anabolic-androgenic steroids or AAS), androstenedione, dehydroepiandrostenedione (DHEA), human growth hormone (hGH; also its human recombinant homologue: rhGH), clenbuterol, creatine, gamma hydroxybutyrate (GHB), amphetamines, caffeine and ephedrine. Also considered are blood doping that includes erythropoietin (EPO) and concepts of gene doping. In the last section of this discussion, we look at disabled pediatric athletes that include such concepts as athletes with spinal cord injuries (SCIs), myelomeningocele, cerebral palsy, wheelchair athletes, and amputee athletes; also covered are pediatric athletes with visual impairment, deafness, and those with intellectual disability including Down syndrome. In addition, concepts of autonomic dysreflexia, boosting and atlantoaxial instability are emphasized. We conclude that clinicians and society should protect our precious pediatric athletes who face many challenges in their involvement with organized sports in a world obsessed with winning. There is much we can do to help our young athletes find benefit from sports play while avoiding or blunting negative consequences of organized sport activities.

Pharmacologic and Acute Management of Spinal Cord Injury in Adults and Children

Purpose of Review

This review provides guidance for acute spinal cord injury (SCI) management through an analytical assessment of the most recent evidence on therapies available for treating SCI, including newer therapies under investigation. We present an approach to the SCI patient starting at presentation to acute rehabilitation and prognostication, with additional emphasis on the pediatric population when evidence is available.

Recent Findings

Further studies since the Surgical Timing in Acute Spinal Cord Injury Study (STASCIS) demonstrated a potential functional outcome benefit with ultra-early surgical intervention ≤ 8 h post-SCI. Subsequent analysis of the National Acute Spinal Cord Injury Study (NASCIS) II and NASCIS III trials have demonstrated potentially serious complications from intravenous methylprednisolone with limited benefit. Newer therapies actively being studied have demonstrated limited or no benefit in preclinical and clinical trials with insufficient evidence to support use in acute SCI treatment.

Summary

Care for SCI patients requires a multi-disciplinary team. Immediate evaluation and management are focused on preventing additional injury and restoring perfusion to the affected cord. Rapid assessment and intervention involve focused neurological examination, targeted imaging, and surgical intervention when indicated. There are currently no evidence-based recommendations for pathomechanistically targeted therapies.
