Guillain-Barré Syndrome After Acute Hepatitis E Infection: A Case Report and Literature Review.

INTRODUCTION: Guillain-Barré syndrome precipitated by hepatitis E virus infection is rare, yet its incidence is increasing. CLINICAL FINDINGS: A 57-year-old man was transferred from another facility with fatigue, orange urine, and progressive weakness over 4 to 6 weeks. Initial laboratory results included total bilirubin, 9.0 mg/dL; direct bilirubin, 6.4 mg/dL; aspartate aminotransferase, 1551 U/L; alanine aminotransferase, 3872 U/L; and alkaline phosphatase, 430 U/L. Immunoglobulin M and quantitative polymerase chain reaction test results were positive for hepatitis E virus. Contrast-enhanced magnetic resonance imaging of the brain and spine showed no gross abnormalities. Analysis of cerebrospinal fluid obtained by lumbar puncture revealed the following (reference values in parentheses): total white blood cell count, 15/µL (0-5/µL), with 33% neutrophils and 54% lymphocytes; protein, 0.045 g/dL (0.015-0.045 g/dL); and glucose, 95 mg/dL (within reference range). Neurological examination revealed weakness in both upper extremities, with proximal strength greater than distal strength. The patient could not elevate either lower extremity off the bed and had areflexia and reduced sensation throughout all extremities. DIAGNOSIS: Guillain-Barré syndrome secondary to acute hepatitis E virus infection was diagnosed on the basis of clinical characteristics, serum and cerebrospinal fluid analyses, and nerve conduction studies. CONCLUSIONS: Nurses and clinicians should obtain a thorough history and consider hepatitis E virus infection as a precipitating factor in patients with sensory and motor disturbances consistent with Guillain-Barré syndrome. The case gives insight into the diagnostic process for Guillain-Barré syndrome and highlights the vital role of bedside nurses in evaluating and treating these patients.

Extrapyramidal Symptoms Induced by Treatment for Delirium: A Case Report.

INTRODUCTION: Antipsychotics are a treatment option for delirium in the intensive care unit. Atypical antipsychotics are preferred over first-generation antipsychotics because of their lower incidence of extrapyramidal adverse effects. The most common such effect is akathisia or restlessness. This report describes a case of atypical antipsychotic-induced akathisia and addresses the clinical distinction between extrapyramidal movements and movements due to intensive care unit delirium. CLINICAL FINDINGS: A 56-year-old man who had a prolonged hospital stay after orthotopic liver transplant complicated by multisystem organ failure, primary graft failure requiring a second transplant, and enterocutaneous fistula developed agitated delirium on hospital day 28. Initial treatment included intravenous haloperidol and scheduled sublingual olanzapine (5 mg daily). His delirium and insomnia persisted, requiring dexmedetomidine infusion. Olanzapine dosing was increased to 10 mg daily on hospital day 34 and 15 mg daily on hospital day 45. The following day, his mentation improved; however, he exhibited asynchronous, nonrhythmic, involuntary rolling motions of his hands and choreiform gait. DIAGNOSIS AND OUTCOMES: Antipsychotics were immediately discontinued owing to acute akathisia. All symptoms resolved within 2 days, and the patient was transferred out of the intensive care unit on hospital day 52. CONCLUSION: Although extrapyramidal adverse effects are less common with olanzapine than with typical antipsychotics, they sometimes occur and can mimic manifestations of delirium. Restlessness should alert the nurse to assess for possible extrapyramidal adverse effects. If they are suspected, antipsychotic medications should be reduced or discontinued to prevent progression to functional disability.

The use of national collaborative to promote advanced practice registered nurse-led high-value care initiatives.

BACKGROUND: High-value healthcare focuses on improving healthcare to produce cost effective care, however limited information on the role of advanced practice registered nurses (APRNs) exists. PURPOSE: This descriptive report describes APRN-led initiatives implemented as part of a national collaborative promoting the Choosing Wisely® campaign and high-value care measures. METHOD: An APRN national collaborative focuses on developing and implementing high-value care initiatives. Monthly calls, podcasts, and a file sharing platform are used to facilitate the work of the national collaborative. FINDINGS: A total of 16 APRN teams from 14 states are participating and have implemented a number of initiatives to reduce unnecessary testing and treatments, promote appropriate antibiotic use, and promote optimal clinical practices such as mobility for hospitalized elderly patients, among others. DISCUSSION: A national collaborative has proven to be a successful way to engage APRN teams to focus on targeting high-value care and promoting evidence-based practices in clinical care.

Reducing chest radiography utilization in the medical intensive care unit.

BACKGROUND AND PURPOSE: Daily chest radiographs (CXRs) have long been a routine part of care. However, evidence as well as changing technology has promoted on-demand CXRs as beneficial to patient care. We found that a substantial number of routine daily CXRs were being ordered, with some of the orders staying active even after extubation. METHODS: Within a 19-bed adult medical ICU, we prospectively utilized 3 intervention phases from October 1, 2014, to February 28, 2018, to reduce routine CXRs. Nurse Practitioners (NP) initiated this quality improvement (QI) project, aiming to reduce the number of unnecessary of CXRs. Interventions included staff survey, routine CXR order removal, duplicate alerts, visual reminders, and an electronic clinical decision support tool. Monthly education of appropriate CXRs and bedside ultrasound were facilitated by NPs. The outcome measures of interest include: the number of CXRs per patient-day, the number of routine and on-demand CXRs, mortality rate, ICU length of stay, and ventilator days, radiation and cost. CONCLUSIONS: Total number of CXRs per patient-day decreased by 36.1%. The proportion of routine CXRs decreased from 55.37% to 13.18%; on-demand orders increased, from 44.63% to 86.82%; and calculated radiation-exposure per census decreased, from 0.011 to 0.008 mSv. In addition, charges to patients for CXRs decreased by $7,750/month. ICU mortality and ventilator days per census remained stable. IMPLICATIONS FOR PRACTICE: By an orchestrated process that included creating awareness and desire to change CXR ordering practices, we were able to decrease routine CXRs and increase on-demand utilization while maintaining counterbalance measures.

Ketamine in seizure management and future pharmacogenomic considerations.

Ketamine is a noncompetitive N-methyl-D-aspartate antagonist with emerging evidence for use in medically refractory epilepsy. We describe the novel use of low-dose intravenous (IV) ketamine transitioning to enteral formulation in a patient with drug-resistant localization-related refractory epilepsy. We performed a National Library of Medicine (NLM) literature review using search terms "ketamine", "low dose", and "seizure" for similar cases, followed by an illustrative clinical case. Our NLM search engine methodology yielded 24 hits, none of which described use of low-dose ketamine for seizures. Anesthetic doses are used for status epilepticus, but we show that in a patient with postoperative worsening of his chronic seizure burden, low-dose IV ketamine can be used to avoid oversedation and intubation. We demonstrate that IV ketamine can be transitioned to oral regimen to shorten length of stay in the intensive care unit and hospital and has future CYP2B6 pharmacogenomic considerations for further dose individualization.

Brief report of a novel advanced practice provider-led course for ultrasound novices.

BACKGROUND AND PURPOSE: Formal training for ultrasound use is essential for critical care providers. Despite a national increase in the utilization of advanced practice providers in critical care, ultrasound education is not routinely provided in their training programs. This study describes and evaluates a 1-day advanced care provider (APP)-led course designed to provide fellow APPs with the skills to obtain and evaluate basic ultrasound images. METHODS: A 15-question pretest was administered via anonymous use of a clicker response system. Participants had didactic lectures followed by hands-on experience with live models and instructor. Posttest was administered after achievement of basic ultrasound views. Postcourse evaluations were also administered. CONCLUSIONS: Pretest and posttest questions included identifying anatomy, pathology, quantifying cardiac function, and clinical decision making. Scores improved from 58% on the pretest to 78% on the posttest. All participants acknowledged the need for the course and their ability to transfer the course into practice. IMPLICATIONS FOR PRACTICE: This course established that APPs can both teach and learn from their peers in a formal setting. In addition, this course demonstrated that an APP-led course with a combined hands-on and didactic approach is an effective method for critical care ultrasound skills acquisition in ultrasound-novice APPs.
