Anesthetic management of a patient with amyotrophic lateral sclerosis for transurethral resection of bladder tumor

Anesthetic Management of a Neurosurgical Patient With Amyotrophic Lateral Sclerosis: A Case Report

Amyotrophic lateral sclerosis (ALS) is a progressive form of neurological disorder that affects both the upper and lower motor neurons. Anesthesia management in these patients is always challenging as they can develop respiratory complications because of pre-existing muscle involvement. We report a middle-aged male with ALS posted for chronic subdural hematoma evacuation (CSDH) surgery. Surgery was done under scalp block with monitored anesthesia care. The choice of anesthesia in these patients should be one that interferes the least with the disease pattern while still providing optimal conditions for surgery.

Hip Fracture in a Patient with Overlap Syndrome - Conundrums Involved in the Management - A Case Report

Introduction

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative condition producing symptoms of varying severity depending on the extent and progression of the disease pathology most importantly respiratory insufficiency and pulmonary complications. Myasthenia gravis (MG) on the other hand is an autoimmune condition due to the pathology involving failure of neuromuscular transmission causing muscle weakness exacerbated by activity and involvement of the respiratory muscles leading to respiratory failure. Overlap syndrome is a condition wherein both motor neuron disease (MND) and MG are present in the same patient. The safety of using muscle-relaxing agents in patients with MG undergoing major surgical procedures has so far been assessed as insufficient. There have been many concerns regarding anesthetic management in relation to complications with respiratory function in patients with ALS, with regional anesthesia being considered slightly safer.

Case Report

An 81-year-old female presented with a closed injury to her left hip, and she was diagnosed to have a left neck of femur fracture. She was also a known case of bulbar MND with an overlap syndrome of MG. She was hypertensive and controlled with regular medication. She was planned for a left hip bipolar arthroplasty. Anesthetic requirements and management of these patients require a high degree of expertise and anesthesia in patients undergoing surgery is prone to more complications and mortality. In addition, as the patient had an overlap of both MG and MND, more meticulous assessment and management strategies were necessary.

Conclusion

The importance and purpose of this study are to highlight a case of overlap syndrome of MND and MG patients who sustained a left neck femur fracture and underwent bipolar arthroplasty highlighting the anesthetic considerations in the patient for the procedure. We concluded that the choice of mode of anesthesia needs to be individualized based on each patient's requirements after careful analysis of the risk-benefit ratio of general versus regional. Regional anesthesia was successfully administered for this patient.

Recurrent Lingual Abscess in an Elderly Female With Bulbar Amyotrophic Lateral Sclerosis

A lingual abscess is a rare condition that was scarcely described in clinical textbooks. A lingual abscess recurrence is rare and has only been described twice in the literature. Typically, the tongue and oral cavity have multiple intrinsic properties which stave off intralingual infection; however, there may be situations in which these properties are compromised, as demonstrated in oro-motor disability. Lingual abscesses have the potential to develop into catastrophic obstructive airway issues; therefore, early detection and management are paramount. The following is a presentation of an elderly female with Bulbar Amyotrophic Lateral Sclerosis (ALS) treated conservatively for a lingual abscess with recurrence at eleven months post-treatment. Due to her baseline neuromuscular disorder and elevated anesthesia risk, she was treated in the interventional radiology suite with drain placement and Povidone-Iodine sclerotherapy under conscious sedation with excellent results. 

Perioperative management of patients with amyotrophic lateral sclerosis: A narrative review

Amyotrophic lateral sclerosis, or motor neuron disease, is an uncommon progressive neurological disorder. Professionals working in the perioperative field may encounter patients with amyotrophic lateral sclerosis only rarely. The relevant published literature on amyotrophic lateral sclerosis is broad in scope, but a contemporary review focused on the perioperative period is absent. This structured narrative review seeks to provide a summary of the contemporary management of patients and then focuses on eliciting if there are perioperative management considerations specific to amyotrophic lateral sclerosis that can be optimised. A comprehensive structured narrative literature review, including grey literature searching, indicated worsening ventilatory failure is of prime concern but that patients may present with a broad range of neurological symptoms, and that cardiovascular and cognitive dysfunction specific to amyotrophic lateral sclerosis may exist and be occult. Exacerbation of neuromuscular weakness during the perioperative period is multifaceted and requires the application of a high standard of the core principles of surgical and anaesthetic management of neuromuscular disease. Standard perioperative approaches require rigorous attention and potential exists for significant alteration. There is a potential high risk of postoperative increased morbidity from neurological decline and mortality from pulmonary complications. A meticulous approach to planning preoperative assessment, shared decision-making, intraoperative and postoperative care is required.

Successful bilevel positive airway pressure therapy in a patient with amyotrophic lateral sclerosis after emergency laparotomy: A case report

Patients with amyotrophic lateral sclerosis (ALS) present an increased risk of postoperative respiratory failure after general anesthesia. We report the case of a 71-year-old man with ALS who underwent emergency laparotomy for small bowel strangulation. After surgery, he remained intubated and was transferred to the high care unit under mechanical ventilation, due to unstable hemodynamics requiring inotropic support. On postoperative day (POD) 3, he was extubated under stable hemodynamics and respiratory status. Immediately after extubation, bilevel positive airway pressure (bilevel PAP) was prophylactically applied to prevent postoperative respiratory failure, which may have been caused by respiratory muscle fatigue, attributed to general anesthesia and surgical stress. On POD 7, bilevel PAP was smoothly weaned off because no signs and symptoms of respiratory failure were observed. On POD 10, he achieved 30 m-walk without rest. No postoperative complications were observed up to one month after surgery. Postoperative respiratory failure may lead to death in patients with neuromuscular disorder. Non-invasive ventilation (NIV) reduces respiratory muscle fatigue, resulting in easy sputum expectoration, promoting CO₂ washout, and better oxygenation. Consequently, the prophylactic use of NIV to avoid postoperative respiratory insufficiency should be considered in patients with ALS after emergency operation under general anesthesia.

Amyotrophic lateral sclerosis and anesthesia: a case series and review of the literature

PURPOSE

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to death due to respiratory failure. This report describes the perioperative characteristics of ALS patients who underwent procedures with anesthesia at our institution.

METHODS

We reviewed perioperative records of ALS patients who underwent procedures with anesthesia from January 1, 2014, through December 31, 2015.

RESULTS

Seventy-eight patients underwent 89 procedures (71 procedures with monitored anesthesia care and 18 with general anesthesia), including 45 gastrostomy tube placements and 18 bone marrow biopsies. Three patients had prolonged duration of postoperative intubation related to preexisting respiratory muscle weakness, and one patient with bilateral pneumothorax required tracheal reintubation for respiratory distress. Four patients had prolonged duration of hospitalization. Three patients were hospitalized for ALS-related complications, and one patient was hospitalized for respiratory distress when pneumoperitoneum developed after gastrostomy tube placement. Three of these patients died of complications attributable to ALS within 30 days of the procedure. Twenty-nine (32.6%) procedures required minimal sedation (e.g., bone marrow biopsy, cataract surgery) and were performed on an ambulatory basis.

CONCLUSION

When caring for patients with ALS, the perioperative team must be prepared to treat potentially complex medical conditions that may not be directly related to the procedure and anesthetic management. However, minor procedures performed with minimal sedation may be safely performed on an ambulatory basis.

Combined spinal-epidural anesthesia with non-invasive ventilation during cesarean delivery of a woman with a recent diagnosis of amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis is the most common neurodegenerative upper and lower motor neuron disease in adults but is not common in women of child-bearing age. We present a case of a pregnant woman who was diagnosed with amyotrophic lateral sclerosis and developed respiratory distress at 32 weeks-of-gestation. She underwent a cesarean delivery under combined spinal-epidural anesthesia with non-invasive ventilation. This resulted in a successful outcome for both the mother and the baby.
