Objective: To evaluate the evidence for the use of intravenous ketamine for analgosedation in the intensive care unit. Methods: MEDLINE and EMBASE were queried from inception until July 2015. Search terms used included ketamine, intensive care, and critical care. The search retrieved 584 articles to be screened for inclusion. The intent was to include randomized controlled studies using sustained intravenous infusions (>24 hours) of ketamine in the critically ill patients. Results: One trial evaluated opioid consumption as an outcome in postoperative critically ill patients who were randomized to ketamine or saline infusions. The mean cumulative morphine consumption at 48 hours was significantly lower in the ketamine group (58 ± 35 mg) compared to the morphine-only group (80 ± 37 mg; P < .05). Other trials showed the potential safety of ketamine in terms of cerebral hemodynamics in patients with traumatic brain injury, improved gastrointestinal motility, and decreased vasopressor requirements. The observational study and case reports suggest that ketamine is safe and effective and may have a role in patients who are refractory to other therapies. Conclusion: Ketamine use may decrease analgesic consumption in the intensive care unit. Additional trials are needed to further delineate the role of ketamine for analgosedation.

Introduction: A low cardiac power output (CPO), measured invasively, identifies critically ill patients at increased risk of mortality. CPO can also be measured non-invasively with transthoracic echocardiography (TTE), although prognostic data in critically ill patients is not available. Hypothesis: Reduced CPO measured by TTE is associated with increased hospital mortality in cardiac intensive care unit (CICU) patients. Methods: Using a database of CICU patients admitted between 2007 and 2018, we identified patients with TTE within one day (before or after) of CICU admission who had data necessary for calculation of CPO. Multivariable logistic regression determined the relationship between CPO and adjusted hospital mortality. Results: We included 5,585 patients with a mean age of 68.3±14.8 years, including 36.7% females. Admission diagnoses included acute coronary syndrome (ACS) in 57%, heart failure (HF) in 50%, cardiac arrest (CA) in 12%, and cardiogenic shock (CS) in 13%. The mean left ventricular ejection fraction (LVEF) was 47±16%, and the mean CPO was 1.0±0.4 W. CPO was inversely associated with the risk of hospital mortality (Figure A), including among patients with ACS, HF, and CS (Figure B). On multivariable analysis, lower CPO was associated with higher hospital mortality (OR 0.96 per 0.1 W, 95% CI 0.0.93-0.99, p=0.03). Hospital mortality was highest in patients with low CPO coupled with reduced LVEF, increased vasopressor requirements, or higher admission lactate. Hospital mortality was higher among patients with a CPO <0.6 W (adjusted OR 1.57, 95% CI 1.13-2.19, p = 0.007), particularly in the presence of admission lactate level >4 mmol/L (50.9%). Conclusions: Echocardiographic CPO was inversely associated with hospital mortality in CICU patients, particularly among patients with increased lactate and vasopressor requirements. Routine measurement of CPO provides important information beyond LVEF and should be considered in CICU patients.

Background: Clonidine is an α2-agonist that is commonly used for sedation in the intensive care unit. When patients are on continuous venovenous hemofiltration (CVVH) in the presence of kidney dysfunction, the sieving coefficient of clonidine is required to estimate how much drug is removed by CVVH. In the present study, we measured the sieving coefficient of clonidine in critically ill, ventilated patients receiving CVVH. Methods: A total of 20 samples of plasma and ultrafiltrate of 3 patients on CVVH, using a standard 1.5 m2 polyacrylonitrile AN69 membrane, during continuous clonidine infusion were collected. After correction for the effect of predilution, we calculated the sieving coefficient for clonidine. Results: The mean sieving coefficient of clonidine was 0.52 (SD 0.097). Conclusion: Using a polyacrylonitrile AN69 membrane in a CVVH machine, the in vivo sieving coefficient of clonidine was 0.52.

Essential Function

A significant role of intensive care unit (ICU) workforce is ongoing communication with and support for families of critically ill patients. The COVID-19 pandemic has created unanticipated challenges to this essential function. Restrictions on visitors to hospitals and unprecedented clinical demands hamper traditional communication between ICU staff and patient families. In response to this challenge, we created a dedicated communications service to provide comprehensive support to families of COVID-19 patients, and to create capacity for our ICU teams to focus on patient care. In this brief report, we describe the development, implementation, and preliminary experience with the service.

BACKGROUND: Critically ill patients are at high risk for pressure ulcers. OBJECTIVES: To determine the contributions of the Braden subscales in predicting pressure ulcers in critically ill patients and to investigate how often the Braden scale should be completed to assess the risk for pressure ulcers in critically ill patients. METHOD: The Braden scale was used to assess repeatedly 136 adult patients without pressure ulcers in a medical intensive care unit, a surgical intensive care unit, and a noninvasive respiratory care unit, and the patients' skin was inspected routinely for pressure ulcers. RESULTS: A total of 36 pressure ulcers, most commonly on the sacrum or coccyx and the heels (15 stage 1, 20 stage 2, 1 stage 3), developed in 17 patients (12%). In 14 (82%) of the 17, the ulcers developed within 72 hours of admission to the intensive care unit. The risk for pressure ulcers increased as the mean sensory perception (P = .01) and the mean total Braden (P = .046) scores decreased. The mean sensory perception scores obtained at 12 and 36 hours after admission also had a significant relationship to the risk for pressure ulcers (P = .03). CONCLUSIONS: Patients in intensive care units have an increased risk for pressure ulcers. Although waiting until 12 hours after a patient's admission to the intensive care unit to obtain the initial Braden rating may be reasonable (with the second rating obtained 36 hours after admission), additional research is needed before this practice can be recommended.

Background: Neurogranin (Ng) concentrates at dendritic spines. In patients with Alzheimer disease Ng levels are elevated. The role of Ng in delirium development has not been assessed, therefore we hypothesized that Ng levels are associated with delirium in critically ill patients. Materials & methods: From 94 critically ill patients, 47 developed delirium and 47 controls were included. Blood was collected during the first 24 h of intensive care unit (ICU) admission, and on the day of delirium diagnoses. Ng and IL-1β were determined. Results: Ng and IL-1β levels were higher in the delirium group at ICU admission and on the day of delirium diagnoses. IL-1β and Ng were independently associated with delirium occurrence. Conclusion: Ng levels are associated with delirium development in ICU patients.

The Mean

The diagnosis of acute cholecystitis in critically ill patients carries a high mortality rate. Although decompression and drainage of the gallbladder through a cholecystostomy tube may be used as a temporary treatment of acute cholecystitis in this population, there is still some debate about the management of the tube and the subsequent need for a cholecystectomy. This series evaluates the clinical course and outcomes of critically ill patients who underwent the insertion of cholecystostomy tubes for the initial treatment of acute cholecystitis. This is a retrospective review of critically ill patients admitted to the hospital intensive care unit who were diagnosed with acute cholecystitis and underwent a cholecystostomy tube as a temporary treatment for the disease. Patients were identified through the Greenville Hospital System electronic medical records coding database. Medical records were reviewed for demographic data, diagnoses, imaging, complications, and outcomes. From January 2002 through June 2008, 50 patients were identified for the study. The mean age was 72 ± 11 years, and the majority (66%) were men. The following comorbidities were found: severe cardiovascular disease (40 patients), respiratory failure (30 patients), and multisystem organ dysfunction (30 patients). The mean intensive care unit length of stay (LOS) was 16 ± 9 days, and the mean hospital LOS was 28 ± 27 days. At 30 days, the morbidity associated with the cholecystostomy tube itself was 4 per cent, but overall in-hospital morbidity and mortality rates were 62 and 50 per cent, respectively. Of the 25 patients who survived longer than 30 days, 12 retained their cholecystostomy tubes until they underwent cholecystectomy (four open, seven laparoscopic). All of the remaining 13 patients had their cholecystostomy tubes removed, and eight developed recurrent cholecystitis. Of these patients with recurrent of cholecystitis, five had cholecystectomy or repeat cholecystostomy, but the remaining three patients died. Although this is a small patient population, these data suggest that, in critically ill patients, cholecystostomy tubes should remain in place until the patient is deemed medically suitable to undergo cholecystectomy. Removal of the cholecystostomy tube without subsequent cholecystectomy is associated with a high incidence of recurrent cholecystitis and devastating consequences.
