weaning sedation

Guillain-Barré syndrome (GBS) is a rare postoperative complication that is sometimes characterized by serious motor weakness and prolonged weaning from mechanical ventilation. Although the exact nature of the relationship between GBS and the surgical procedure is still unclear, there is a clear increased incidence of GBS in post-surgical patients compared to non-surgical patients. GBS after surgery is unique in several ways. The course of post-surgical GBS unfolds more rapidly than in other situations where GBS develops, the condition is often more severe, and respiratory muscles are more commonly involved...

OBJECTIVE: To compare reintubation rates after planned extubation and unplanned extubation (UE) in patients in neonatal intensive care units (NICUs), to analyse risk factors for reintubation after UE and to compare outcomes in patients with and without UE. DESIGN: Prospective, observational study nested in a randomised controlled trial (SEPREVEN/Study on Epidemiology and PRevention of adverse EVEnts in Neonates). Outcomes were expected to be independent of the intervention tested...

AIMS: Drug-refractory electrical storm (ES) is a life-threatening medical emergency. We describe the use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in drug-refractory ES without a reversible trigger, for which specific guideline recommendations are still lacking. METHODS AND RESULTS: Retrospective observational study in four Iberian centres on the indications, treatment, complications, and outcome of drug-refractory ES not associated with acute coronary syndromes, decompensated heart failure, drug toxicity, electrolyte disturbances, endocrine emergencies, concomitant acute illness with fever, or poor compliance with anti-arrhythmic drugs, requiring VA-ECMO for circulatory support...

OBJECTIVE: Gabapentin for management of neuropathic pain, irritability, neonatal abstinence syndrome, rescue sedation, feeding intolerance and visceral hyperalgesia in infants has grown over the past decade. There remains little guidance for indications, initiation, titration and maintenance dosing trends and assessment of outcomes. The primary objective was to describe gabapentin dosing, and the secondary objectives were to identify outcomes to assess efficacy and describe weaning practices...

BACKGROUND: There is limited literature regarding family and staff experiences of participating in clinical trials. A qualitative study was embedded in the NAVABronch feasibility trial evaluating the effectiveness of a novel mode of ventilation, neurally adjusted ventilatory assist (NAVA), in infants with acute viral bronchiolitis. AIMS AND OBJECTIVES: The aim of this qualitative study was to explore the experiences of parents and health care practitioners (HCPs) involved in the NAVABronch Trial...

Bromvalerylurea (BVU) is a sedative-hypnotic drug with a high risk of acute poisoning. In the present case, hemodialysis (HD) was introduced in a patient with severe BVU poisoning who later demonstrated respiratory arrest, and then HD clearances (CLHD ) were assessed in detail. A 20-year-old female was transported to the emergency department by ambulance, an estimated two to four hours after orally ingesting 144 tablets of Utto® (12,000 mg BVU) in a suicide attempt. The patient was comatose on arrival...

Mechanical circulatory support (MCS) as a bridge to lung transplant is an infrequent but accepted pathway in patients who have refractory end-stage pulmonary failure. The American Association of Thoracic Surgeons Expert Consensus Guidelines, published in 2023, recommends venovenous (VV) extracorporeal membrane oxygenation (ECMO) as the initial configuration for those patients who have failed conventional medical therapy, including mechanical ventilation, while waiting for lung transplantation and needing MCS...

BACKGROUND: Overuse of sedation and anesthesia causes delays in gastrojejunostomy tube (GJ) exchanges, increased risk of complications, unnecessary use of resources, preventable hospital admissions, and an adverse impact on patient and family experience. Our hospital was over-utilizing sedation and anesthesia, and we aimed to decrease this use from 78% to 20% within two years. METHODS: An interdisciplinary quality improvement team comprehensively evaluated current processes for GJ tube exchanges through a retrospective chart review for baseline data with prospective time series analysis after improvement implementation...

BACKGROUND: Sedation management has a major impact on outcomes in mechanically ventilated patients, but sedation strategies do not generally consider the differential effects of different sedatives on respiration and respiratory pattern. A systematic review was undertaken to quantitatively summarize the known effects of different classes of drugs used for sedation on respiratory pattern during both spontaneous breathing and assisted mechanical ventilation. METHODS: This was a systematic review and meta-analysis conducted using Ovid MEDLINE, Embase, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials up to June 2020 to retrieve studies that measured respiratory parameters before and after the administration of opioids, benzodiazepines, intravenous and inhaled anaesthetic agents, and other hypnotic agents (PROSPERO #CRD42020190017)...

Mechanical ventilation (MV) has played a crucial role in the medical field, particularly in anesthesia and in critical care medicine (CCM) settings. MV has evolved significantly since its inception over 70 years ago and the future promises even more advanced technology. In the past, ventilation was provided manually, intermittently, and it was primarily used for resuscitation or as a last resort for patients with severe respiratory or cardiovascular failure. The earliest MV machines for prolonged ventilatory support and oxygenation were large and cumbersome...

Acute respiratory failure (ARF) is associated with significant morbidity and mortality in trauma and emergency surgery patients. Pulmonary complications following surgery among the most frequent and costly postoperative events. ARF support with mechanical ventilation is life-saving but may lead to ventilator-induced lung injury (VILI), worsening secondary injury. Decades of randomized clinical trials have demonstrated that evidence-based ventilator management can improve outcomes, but one-size-fits-all mechanical ventilation protocols fail to achieve true individualized, personalized care for ARF...

Status epilepticus (SE) is a common medical emergency associated with significant morbidity and mortality. Management that follows published guidelines is best suited to improve outcomes, with the most severe cases frequently being managed in the intensive care unit (ICU). Diagnosis of convulsive SE can be made without electroencephalography (EEG), but EEG is required to reliably diagnose nonconvulsive SE. Rapidly narrowing down underlying causes for SE is crucial, as this may guide additional management steps...

CONTEXT: After the COVID-19 pandemic, multiple reviews have documented the success of veno-arterial extracorporeal membrane oxygenation (VA-ECMO). Patients who experience hypoxemia but have normal contractility may be switched to veno-venous-ECMO (VV-ECMO). PURPOSE: In this review, we present three protocols for anesthesiologists. Firstly, transesophageal echocardiography (TEE) aids in cannulation and weaning off inotropes and fluids. Our main objective is to assist in patient selection for the Avalon Elite single catheter, which is inserted into the right internal jugular vein and terminates in the right atrium...

BACKGROUND: Prolonged mechanical ventilation increases the risk of mortality and morbidity. Optimising sedation and early testing for possible liberation from invasive mechanical ventilation (IMV) has been shown to reduce time on the ventilator. Alongside a multicentre trial of sedation and ventilation weaning, we conducted a mixed method process evaluation to understand how the intervention content and delivery was linked to trial outcomes. METHODS: 10,495 children admitted to 18 paediatric intensive care units (ICUs) in the United Kingdom participated in a stepped-wedge, cluster randomised controlled trial, with 1955 clinical staff trained to deliver the intervention...

The aim of the study was to compare the efficacy of the intranasal and parenteral administration of azaperone in order to achieve pig sedation. A total of 32 weaned piglets divided into 4 groups (8 piglets in each group) were used. Group A was injected intramuscularly (i.m.) with azaperone (Stresnil® , 40 mg/ml inj.; Elanco Animal Health) at a dose of 2 mg/kg of body weight (b.w.). Group B received a dose of 2 mg/kg b...

OBJECTIVES: Extracorporeal membrane oxygenation (ECMO) is an advanced treatment for acute severe respiratory failure. Patients on ECMO are frequently maintained sedated and immobilized until weaning from ECMO, first, and then from mechanical ventilation. Avoidance of sedation and invasive ventilation during ECMO may have potential advantages. We performed a systematic literature review to assess efficacy and safety of awake ECMO without invasive ventilation in patients with respiratory failure...

Melatonin, which is produced from tryptophan, exerts various biological functions, including the regulation of circadian rhythm, sedative agents, and antioxidant ability. Therefore, we conducted two experiments with early-weaned rats and pigs to investigate the antioxidant and sedative effects of melatonin. In the rat experiment, a total of 42 rats (21 days old) were used, and the antioxidant capacity was determined. Next, we used 120 early-weaned piglets (21 days old) to conduct a 5-week experiment to evaluate the reductive effect of melatonin on energy-wasting movement, including roaming and fight states...

BACKGROUND: Unplanned extubating is the most common adverse event occurring in intensive care units (ICUs) and significantly increases morbidity and mortality in children, but there is limited current evidence on unplanned extubating in Ethiopia. Therefore, this study aimed to determine the incidence, outcome, and determinants of unplanned extubating among children in the pediatric intensive care unit in Addis Ababa, Ethiopia, in 2023. METHODS: A nested unmatched case-control design study was conducted at selected government hospitals in Addis Ababa from September 1, 2022, to April 30, 2023...

This report highlights survival and the patient's perspective after prolonged venovenous extracorporeal membrane oxygenation (ECMO) for COVID-19-related respiratory failure. A 36-year-old man with COVID-19 presented with fever, anosmia, and hypoxia. After respiratory deterioration necessitating intubation and lung-protective ventilation, he was referred for ECMO. After 3 days of conventional venovenous ECMO, he required multiple creative cannulation configurations. Adequate sedation and recurrent bradycardia were persistent challenges...

INTRODUCTION AND IMPORTANCE: Organophosphate (OP) poisoning is a common and potentially fatal condition that requires prompt and aggressive treatment with atropine, oximes, and supportive care. We report a rare case of OP poisoning that needed high doses of atropine and intensive care for 60 days. CASE PRESENTATION: A 39-year-old male ingested 200 ml of chlorpyrifos, an OP compound, and presented with vomiting and epigastric pain. He received an initial dose of atropine of 60 ml (36 mg, 1 ml=0...
