Diving marine mammals are a diverse group of semi- to completely aquatic species. Some species are targets of conservation and rehabilitation efforts; other populations are permanently housed under human care and may contribute to clinical and biomedical investigations. Veterinary medical care for species under human care, at times, may necessitate the use of general anesthesia for diagnostic and surgical indications.

Introduction: Use of mechanical ventilation during general anesthesia is a necessary practice in the anesthetization of small cetaceans as spontaneous ventilation fails to provide adequate gas exchange. Currently available methods of ventilation do not account for the intermittent breathing strategy of representative species within this infraorder of fully aquatic mammals and may have a significant effect on cardiac and respiratory physiology.

Methods: To understand the impact of mechanical ventilation on cardiopulmonary function in one small species of cetacean, the bottlenose dolphin (), we compared controlled mechanical ventilation (CMV) to a novel ventilation method known as apneustic anesthesia ventilation (AAV).

(1) Background: When a human or animal is recovering from general anesthesia, their medical team uses several behavioral and physiological parameters to assess their emergence from the unconscious state to complete wakefulness. However, the return of auditory and acoustic behaviors indicative of the complete return of consciousness in humans can be difficult to assess in a completely aquatic non-human mammal. Dolphins produce sound using the nasal system while using both passive auditory and active biological sonar (echolocation) to navigate and interrogate their environment.

Between 2009 and 2018, five common bottlenose dolphins () at the US Navy Marine Mammal Program presented with superficial cervical lymphadenitis. Clinical findings included ultrasonographic evidence of cervical lymph node enlargement, severe leukocytosis, elevated erythrocyte sedimentation rates, and reduced serum iron. Three of the dolphins presented with clinicopathologic changes without presence of clinical signs, and the other two cases additionally presented with partial to complete anorexia, lethargy, and refusal to participate in training sessions.

Domoic acid (DA) is a naturally occurring marine neurotoxin produced by Pseudo-nitzschia diatoms. Adult California sea lions (Zalophus californianus) can experience multiple post-exposure syndromes, including acute toxicosis and chronic epilepsy. Additionally, a delayed-onset epileptic syndrome is proposed for California sea lions (CSL) exposed in utero.

Background: Generalised convulsive status epilepticus (GCSE) is a medical emergency. Guidelines recommend a stepwise strategy of benzodiazepines followed by a second-line anti-seizure medicine (ASM). However, GCSE is uncontrolled in 20-40% patients and is associated with protracted hospitalisation, disability, and mortality.

Article Synopsis
  • The study aimed to evaluate the cardiopulmonary effects of apneustic anesthesia ventilation (AAV) versus conventional mechanical ventilation (CMV) in anesthetized horses.
  • Ten healthy horses were used in a randomized crossover design, measuring various cardiopulmonary parameters over one hour after administration of anesthetics and controlled ventilation.
  • Results indicated that AAV led to improved respiratory indices compared to CMV, though both methods provided sufficient oxygenation; however, many parameters showed no significant differences between the two ventilation methods.

Although noninvasive ventilation (NIV) may prevent reintubation in patients at high risk of extubation failure in ICUs, this oxygenation strategy has not been specifically assessed in obese patients. We hypothesized that NIV may decrease the risk of reintubation in obese patients compared with high-flow nasal oxygen. analysis of a multicenter randomized controlled trial (not prespecified) comparing NIV alternating with high-flow nasal oxygen versus high-flow nasal oxygen alone after extubation, with the aim of assessing NIV effects according to patient body mass index (BMI).

Background: In intensive care units (ICUs), patients experiencing post-extubation respiratory failure have poor outcomes. The use of noninvasive ventilation (NIV) to treat post-extubation respiratory failure may increase the risk of death. This study aims at comparing mortality between patients treated with NIV alternating with high-flow nasal oxygen or high-flow nasal oxygen alone.

Background: Several randomized clinical trials have shown that non-invasive ventilation (NIV) applied immediately after extubation may prevent reintubation in patients at high-risk of extubation failure. However, most of studies included patients with chronic respiratory disorders as well as patients without underlying respiratory disease. To date, no study has shown decreased risk of reintubation with prophylactic NIV after extubation among patients with chronic obstructive pulmonary disease (COPD).

Background: Delayed intubation is associated with high mortality. There is a lack of objective criteria to decide the time of intubation. We assessed a recently described combined oxygenation index (ROX index) to predict intubation in immunocompromised patients.

Purpose: Hyperbilirubinemia is frequent in patients with hematological malignancies admitted to the intensive care unit (ICU). Literature about hepatic dysfunction (HD) in this context is scarce.

Methods: We investigated the prognostic impact of HD analyzing a prospective multicenter cohort of 893 critically ill hematology patients.

Objectives: Early intensive care unit (ICU) admission, in Critically Ill Cancer Patients (CICP), is believed to have contributed to the prognostic improvement of critically ill cancer patients. The primary objective of this study was to assess the association between early ICU admission and hospital mortality in CICP.

Design: Retrospective analysis of a prospective multicenter dataset.

Background: Spontaneous breathing trial (SBT) using a T-piece remains the most frequently performed trial before extubation in ICUs.

Research Question: We aimed at determining whether initial SBT using pressure-support ventilation (PSV) could increase successful extubation rates among patients at high risk of extubation failure.

Study Design And Methods: Post hoc analysis of a multicenter trial focusing on reintubation in patients at high-risk of extubation failure.

Background: The aim of this study was to assess the benefit of direct ICU admission from the emergency department (ED) compared to admission from wards, in patients with hematological malignancies requiring critical care.

Methods: Post hoc analysis derived from a prospective, multicenter cohort study of 1011 critically ill adult patients with hematologic malignancies admitted to 17 ICU in Belgium and France from January 2010 to May 2011. The variable of interest was a direct ICU admission from the ED and the outcome was in-hospital mortality.

Importance: High-flow nasal oxygen may prevent postextubation respiratory failure in the intensive care unit (ICU). The combination of high-flow nasal oxygen with noninvasive ventilation (NIV) may be an optimal strategy of ventilation to avoid reintubation.

Objective: To determine whether high-flow nasal oxygen with prophylactic NIV applied immediately after extubation could reduce the rate of reintubation, compared with high-flow nasal oxygen alone, in patients at high risk of extubation failure in the ICU.

Background: Acute respiratory failure is the leading reason for intensive care unit (ICU) admission in immunocompromised patients, and the need for invasive mechanical ventilation has become a major clinical endpoint in randomized controlled trials (RCTs). However, data are lacking on whether intubation is an objective criteria that is used unbiasedly across centers. This study explores how this outcome varies across ICUs.

Aspergillosis is a fungal infection caused by Aspergillus molds that can affect both humans and animals. Despite advances in diagnostics and therapy, medical management of this disease remains difficult. Expansion of the basic knowledge regarding its pathophysiology in animals is critical to aid in the identification of new biomarkers of infection for diagnosis and therapeutic targets.

Background: Whether providing nutrition support is beneficial or deleterious during targeted temperature management (TTM) after cardiac arrest is unclear. We therefore performed a retrospective observational study to determine whether early nutrition was beneficial or deleterious during TTM.

Methods: We retrospectively studied patients admitted to our intensive care unit (ICU) between 2008 and 2014 after successfully resuscitated cardiac arrest.
