The LiberAction Project: Implementation of a Pediatric Liberation Bundle to Screen Delirium, Reduce Benzodiazepine Sedation, and Provide Early Mobilization in a Human Resource-Limited Pediatric Intensive Care Unit

Background: Delirium, bed immobilization, and heavy sedation are among the major contributors of pediatric post-intensive care syndrome. Recently, the Society of Critical Care Medicine has proposed the implementation of daily interventions to minimize the incidence of these morbidities and optimize children functional outcomes and quality of life. Unfortunately, these interventions require important clinical and economical efforts which prevent their use in many pediatric intensive care units (PICU).Aim: First, to evaluate the feasibility and safety of a PICU bundle implementation prioritizing delirium screening and treatment, early mobilization (<72 h from PICU admission) and benzodiazepine-limited sedation in a human resource-limited PICU. Second, to evaluate the incidence of delirium and describe the early mobilization practices and sedative drugs used during the pre- and post-implementation periods. Third, to describe the barriers and adverse events encountered during early mobilization.Methods: This observational study was structured in a pre- (15th November 2019–30th June 2020) and post-implementation period (1st July 2020–31st December 2020). All patients admitted in PICU for more than 72 h during the pre and post-implementation period were included in the study. Patients were excluded if early mobilization was contraindicated. During the pre-implementation period, a rehabilitation program including delirium screening and treatment, early mobilization and benzodiazepine-sparing sedation guidelines was developed and all PICU staff trained. During the post-implementation period, delirium screening with the Connell Assessment of Pediatric Delirium scale was implemented at bedside. Early mobilization was performed using a structured tiered protocol and a new sedation protocol, limiting the use of benzodiazepine, was adopted.Results: Two hundred and twenty-five children were enrolled in the study, 137 in the pre-implementation period and 88 in the post-implementation period. Adherence to delirium screening, benzodiazepine-limited sedation and early mobilization was 90.9, 81.1, and 70.4%, respectively. Incidence of delirium was 23% in the post-implementation period. The median cumulative dose of benzodiazepines corrected for the total number of sedation days (mg/kg/sedation days) was significantly lower in the post-implementation period compared with the pre-implementation period: [0.83 (IQR: 0.53–1.31) vs. 0.74 (IQR: 0.55–1.16), p = 0.0001]. The median cumulative doses of fentanyl, remifentanil, and morphine corrected for the total number of sedation days were lower in the post-implementation period, but these differences were not significant. The median number of mobilizations per patient and the duration of each mobilization significantly increased in the post-implementation period [3.00 (IQR: 2.0–4.0) vs. 7.00 (IQR: 3.0–12.0); p = 0.004 and 4 min (IQR: 3.50–4.50) vs. 5.50 min (IQR: 5.25–6.5); p < 0.0001, respectively]. Barriers to early mobilization were: disease severity and bed rest orders (55%), lack of physicians' order (20%), lack of human resources (20%), and lack of adequate devices for patient mobilization (5%). No adverse events related to early mobilization were reported in both periods. Duration of mechanical ventilation and PICU length of stay was significantly lower in the post-implementation period as well as the occurrence of iatrogenic withdrawal syndrome.Conclusion: This study showed that the implementation of a PICU liberation bundle prioritizing delirium screening and treatment, benzodiazepine-limited sedation and early mobilization was feasible and safe even in a human resource-limited PICU. Further pediatric studies are needed to evaluate the clinical impact of delirium, benzodiazepine-limited sedation and early mobilization protocols on patients' long-term functional outcomes and on hospital finances.

Advance Care Planning Among Healthcare Professionals During COVID-19

The COVID-19 pandemic is bringing healthcare professionals face to face with gravely ill patients in complex clinical situations. Caring for patients experiencing lengthy intubation, heavy sedation, rapid decline, and significant distress at the end of life has the potential to shift the perspectives of healthcare professionals regarding their own end-of-life care. This study explored advance care planning (ACP) among medical professionals and whether COVID-19 experiences altered their healthcare preferences and planning. Ninety-eight professionals (mean age = 45.6, 75% female) completed an online survey about ACP conversations, behavioral intentions to pursue ACP, openness to life-prolonging interventions, and ACP resource needs. ACP conversations were most extensive with spouse/partner (89% had talked about care preferences “some” or “a lot”) and to a lesser extent with parents (64%) and other healthcare providers (69%). Two-thirds (67%) of respondents had an ACP conversation since the start of COVID. Among respondents who had not completed ACP documents, 64% had taken some step toward ACP. When asked whether their preferences for life-prolonging medical interventions had changed, 70% reported no change, 16% reported being less open, and 14% reported being more open. A majority (60%) requested resources to help them pursue ACP on their own, although many (42%) were interested in assistance at their workplace. Given that only 37% of our sample had themselves completed an advance directive, our results suggest now may be a critical moment to engage professionals in ACP, considering how their experience during the pandemic has motivated ACP conversations and a reconsideration of preferences.

551 Fish Skin Compared to Cadaver Skin as a Temporary Coverage and Wound Bed Preparation for Full Thickness Burns: An Early Feasibility Trial.

Introduction Full-thickness thermal burns may require staged procedures with temporary coverage to ensure the wound bed is optimized for autografting. A potential dermal substitute for thermal injury is fish skin grafts. These are made in Iceland from freeze dried, sterilized, decellularized skin of North Atlantic cod (Gadus morhua). The gentle processing of the fish skin removes the risk of viral disease transmission to humans and retains its naturally occurring Omega3 fatty acids which are known for their pain and inflammation modulating effects. Fish skin graft has a shelf life of 3 years at room temperature, whereas cadaver skin, the current standard of care at many institutions, has to be cryopreserved, is donor derived, and contains only trace amounts of Omega3. While fish skin graft has been cleared by the FDA as a medical device for use in acute, surgical, chronic wounds, and partial thickness burns, it has not yet been indicated for use in full-thickness burns. The purpose of this clinical trial is to assess the safety and efficacy of decellularized, freeze dried fish skin as an alternative to cadaveric skin (standard of care) for temporary coverage in the setting of a full-thickness burn requiring staged grafting. Methods Patients with full thickness burns to their extremities and/or chest were randomized to have two adjacent areas (70–140 cm2 each) covered with either fish skin or cadaver skin for one week following excision. Patients then received a split thickness skin graft (STSG). Healing was observed by blinded assessors for each area weekly for three weeks, with a scarring assessment completed at 3 months post STSG. Background pain was measured by a visual analogue scale (VAS) for pain and wounds were photographed at each time point. Results Five patients are included in this initial analysis and all completed the 3-month post STSG follow up. TBSA ranged from 8–37%. The fish skin treated area was assessed to be 90% healed at the same timeframe or earlier than cadaver treated areas in all subjects. There was a trend towards a reduction in pain in the fish skin covered areas. One patient was unable to give a pain score due to heavy sedation. Adverse events were reported in all five patients, but none were associated with the use of the investigational product. Graft failures were observed in two cadaver skin covered areas and one partial failure in a fish skin covered area. Conclusions Results from this trial so far indicate that the fish skin is safe and non-inferior to cadaver skin as an early coverage for full thickness burns. Enrollment in this study is still ongoing, and patients will be followed up for 12 months.

Sustained normothermia in septic shock and the energy transfer required: a report of a pilot feasibility study using newer-generation surface cooling devices

There is significant uncertainty about the potential role of temperature control in the intensive care unit (ICU) in general, but more specifically in septic shock patients.1,2 Common techniques for temperature control have been limited by minimal effect (eg, paracetamol, fans or air blankets), undesirable side effects (eg, non-steroidal anti-inflammatories), or being burdensome (eg, heavy sedation, paralysis with surface cooling; intravascular cooling devices3). In contrast, the potential of newer-generation surface-cooling devices to achieve temperature control more simply has created the possibility of studying temperature modulation in the septic ICU population.

Neurotropism of SARS-CoV-2: COVID-19 presenting with an acute manic episode

A 41-year-old man with no significant medical history presented with acute behavioural disruption on the background of a 1-day history of severe headache and a 10-day history of dry cough and fever. He was sexually disinhibited with pressured speech and grandiose ideas. His behaviour worsened, necessitating heavy sedation and transfer to intensive care for mechanical ventilation despite no respiratory indication. Investigations confirmed that he was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Neuroimaging and a lumbar puncture were normal. Initial screening for SARS-CoV-2 in the cerebrospinal fluid was negative although no validated assay was available. The patient’s mental state remained abnormal following stepdown from intensive care. Psychiatric assessment found features consistent with acute mania, and he was detained under the Mental Health Act. This case indicates the need to consider COVID-19 in a wider series of clinical presentations and to develop a validated assay for SARS-CoV-2 in the cerebrospinal fluid.

Is periprocedural sedation during acute stroke therapy associated with poorer functional outcomes?

BackgroundTo safely perform acute intra-arterial revascularization procedures, use of sedative medications and paralytics is often necessary. During the conduct of the Interventional Management of Stroke trials (I and II), the level of sedation used periprocedurally varied. At some institutions, patients were paralyzed and intubated as part of the procedural standard of care while at other institutions no routine sedation protocol was followed. The aim of this study was to identify patient characteristics that would correlate with the need for deeper sedation and to explore whether levels of sedation relate to patient outcome.Methods75 of 81 patients in the Interventional Management of Stroke II Study were studied. Patients had anterior circulation strokes and underwent angiography and/or intervention. Four sedation categories were defined and tested for factors potentially associated with the level of sedation. Clinical outcomes were also analyzed, including successful angiographic reperfusion and the occurrence of clinical complications.ResultsOnly baseline National Institutes of Health Stroke Scale varied significantly by sedation category (p=0.01). Patients that were in the lower sedation category fared better, having a higher rate of good outcomes (p<0.01), lower death rates (p=0.02) and higher successful angiographic reperfusion rates (p=0.01). There was a significantly higher infection rate in patients receiving heavy sedation or pharmacologic paralysis (p=0.02) and a trend towards fewer groin related complications.ConclusionIn this small sample, patients not receiving sedation fared better, had higher rates of successful angiographic reperfusion and had fewer complications. Further examination of the indications for procedural sedation or paralysis and their effect on outcome is warranted.

“They Medicated Me Out”

Addiction, a cultural construct long framed in moral, psychological, and social terms, is increasingly understood as biological and treated with medications. In the United States, methadone, buprenorphine, and a variety of psychopharmaceuticals are now commonly used to treat addiction alongside long-standing approaches such as 12-Step mutual aid. These biomedical interventions reshape the very condition they intervene on, influencing the ways treatment clients understand and experience addiction. Clients often experience medication treatment in tension with embodied and social practices of addiction: bodily routines, sensory experiences, temporalities, and social contexts of use. This article examines these tensions through theories of the social flesh and embodied citizenship. This analysis is based on a 20-month ethnography in and around “Sunrise” residential center in Northeast Ohio. Sunrise merges biomedical interventions with 12-Step, psychological and juridical approaches. These data show how biomedical practices alter client bodies and subjectivities, promoting body alienation at stark odds with the intense bodily connection clients established through drug use. This alienation results from rapid weight gain and heavy sedation clients attribute to medication effects, as well as mandated medication and adherence practices that strip clients of a sense of control of medication use. Many clients describe feeling “medicated out” of life: estranged from treatment peers and kin who oppose medications, counselors and other powerful authorities who demand their undivided attention, and friends with whom they are unable to relate when heavily medicated. Clients, however, do not passively accept this estrangement. They alter their bodily experiences by leveraging embodied practices developed during drug use. Through practices such as selectively taking medications based on historical bodily experience and illegal drug “testing” in the underground economy, clients reassert bodily connection and control, deriving a modicum of power—albeit constrained and risky—in a treatment system that strictly limits it.

Extubation in Patients Undergoing Extracorporeal Life Support

Purpose Extracorporeal life support (ECLS) is a cardiopulmonary support system used for the treatment of severe cardiac and/or respiratory failure. Mortality is high partly because of the severity of the condition that requires support. The use of ECLS is generally associated with heavy sedation. The aim of this study was to demonstrate the feasibility of stopping sedation, allowing extubation of patients supported by ECLS. Methods 196 patients supported by ECLS for a period of 4 years were included. Sedation was stopped as soon as possible to allow extubation. The 44 extubated patients were compared with non-extubated patients. Finally, 24% of patients were not extubated without a determined cause and were compared with extubated patients. Results The extubated patients had a lower incidence of ventilator-associated pneumonia. In a multivariate analysis, the independent risk factors for death were the duration of ECLS, age and lack of extubation. Stopping sedation and extubation are feasible in selected patients under ECLS. Conclusions This strategy could be a survival factor.
