CASE SUMMARY: A 6 yr old 45 kg child with severe Cushinoid features was admitted to PICU with probable hypertensive encephalopathy. She presented with increasing headaches, vomiting and seizures becoming unresponsive with a GCS of 3. She was profoundly hypertensive and her cortisol levels were significantly elevated (>2000 nmol/L). Rapid reduction in cortisol levels was required to stabilise her condition prior to surgery. Etomidate is the only readily available intravenous preparation which reliably suppresses adrenocortical function...

A 58-year male patient was admitted to the intensive care unit of our hospital due to an exacerbated COPD (GOLD IV) complicated by a pneumonia. The clinical course deteriorated despite of evidence based intensive care treatment and lungprotective ventilation, a vv-ECMO and a volatile sedation were established. After a few days vv-ECMO could be discontinued and the patient was discharged from hospital after 20 days.Our case report suggests that early support with vv-ECMO could reduce the cumulative duration of invasive ventilation in case of severe COPD exacerbation...

Rationale Ventilator-induced Diaphragm Dysfunction is a significant contributor to weaning difficulty in ventilated critically ill patients. It has been hypothesized that electrically pacing the diaphragm during mechanical ventilation could reduce diaphragm dysfunction. Objectives We tested a novel, central line catheter-based, transvenous phrenic nerve pacing therapy for protecting the diaphragm in sedated and ventilated pigs. Methods Eighteen Yorkshire pigs were studied. Six pigs were sedated and mechanically ventilated for 2...

BACKGROUND: Traditional sedation for mechanically ventilated patients causes delirium, which increases the patients' length of stay while hospitalized. When extubation is attempted, these medications must be discontinued because of the side effect of respiratory depression, leaving patients anxious and agitated, delaying extubation and prolonging the need for mechanical ventilation. Dexmedetomidine is a safe alternative sedative that does not cause delirium or respiratory depression. During the weaning process, dexmedetomidine can be continued, allowing the patient to remain calm and successfully extubated...

Background. Spontaneous breathing trials (SBTs) are standard of care in assessing extubation readiness; however, there are no universally accepted guidelines regarding their precise performance and reporting. Objective. To investigate variability in SBT practice across centres. Methods. Data from 680 patients undergoing 931 SBTs from eight North American centres from the Weaning and Variability Evaluation (WAVE) observational study were examined. SBT performance was analyzed with respect to ventilatory support, oxygen requirements, and sedation level using the Richmond Agitation Scale Score (RASS)...

INTRODUCTION: Intrathecal baclofen (ITB) screening assesses response to a test dose of ITB on spasticity and function and identifies adverse reactions. METHOD: An expert panel consulted on best practices after conducting an extensive literature search and conducting an online survey. RESULTS: A successful trial may confirm predetermined goals, which may include improved mobility/positioning, decreased time/improved independence for activities, less home exercise, better wheelchair tolerance, decreased caregiver time, improved sleep, and reduced pain, or may modify goals and expectations...

Prolonged use of sedative medications continues to be a concern for critical care practitioners, with potential adverse effects including tolerance and withdrawal. The amount of sedatives required in critically ill patients can be lessened and tolerance delayed with the use of pain and/or sedation scales to reach the desired effect. The current recommendation for prolonged sedation is to wean patients from the medications over several days to reduce the risk of drug withdrawal. It is important to identify patients at risk for iatrogenic withdrawal and create a treatment strategy...

Trauma patients experience pain and agitation during their hospitalization. Many complications have been noted both in the absence of symptom management and the in presence of oversedation/narcotization. To combat noted untoward effects of pain and sedation management, an interprofessional team convened to develop a pain and sedation guideline for use in a trauma intensive care unit. Guideline development began with a comprehensive review of the literature. With the input of unit stakeholders, a nurse-driven analgosedation guideline was implemented for a 6-month trial...

The international classification of three weaning categories (simple weaning, difficult weaning, prolonged weaning) has been modified in the German weaning guidelines: the group of prolonged weaning has been subclassified into weaning without noninvasive ventilation (NIV), weaning with NIV, if necessary with continuing NIV in the form of home mechanical ventilation, and weaning failure.Strategies to prevent prolonged weaning comprise daily interruption of sedation, daily screening of capability of spontaneous breathing by a spontaneous breathing trial (SBT) and early implementation of NIV instead of continuing invasive mechanical ventilation especially in hypercapnic patients...
