RESUMO
Objective: Describe continuous infusion (CI) ketamine practices in pediatric intensive care units (PICUs) and evaluate its effect on pain/sedation scores, exposure to analgesics/sedatives, and adverse effects (AEs). Methods: Multicenter, retrospective, observational study in children <18 years who received CI ketamine between 2014 and 2017. Time spent in goal pain/sedation score range and daily cumulative doses of analgesics/sedatives were compared from the 24 hours (H) prior to CI ketamine to the first 24H and 25-48H of the CI. Adverse effects were collected over the first 7 days of CI ketamine. Results: Twenty-four patients from 4 PICUs were included; median (IQR) age 7 (1-13.25) years, 54% female (n = 13), 92% intubated (n = 22), 25% on CI vasopressors (n = 6), and 33% on CI paralytics (n = 8). Ketamine indications were analgesia/sedation (n = 21, 87.5%) and status epilepticus (n = 3, 12.5%). Median starting dose was 0.5 (0.48-0.70) mg/kg/hr and continued for a median of 2.4 (1.3-4.4) days. There was a significant difference in mean proportion of time spent within goal pain score range (24H prior: 74% ± 14%, 0-24H: 85% ± 10%, and 25-48H: 72% ± 20%; p=0.014). A significant reduction in median morphine milligram equivalents (MME) was seen (24H prior: 58 (8-195) mg vs. 0-24H: 4 (0-69) mg and p=0.01), but this was not sustained (25-48H: 24 (2-246) mg and p=0.29). Common AEs were tachycardia (63%), hypotension (54%), secretions/suctioning (29%), and emergence reactions (13%). Conclusions: Ketamine CI improved time in goal pain score range and significantly reduced MME, but this was not sustained. Larger prospective studies are needed in the pediatric population.
RESUMO
PURPOSE: Cannabis utilization has increased over time for recreational and medical purposes due to its legalization or decriminalization. The effects of cannabis use on opioid utilization are not well understood. The primary objective was to evaluate the total opioid utilization, measured in morphine milligram equivalents (MME), in hospitalized trauma patients that tested positive for tetrahydrocannabinol (THC) on a urine drug screen (UDS). METHODS: This was a retrospective, cohort study in a level 1 trauma center between 10/17/17 and 12/31/19. Adult trauma patients (aged 15 years and older) who had a UDS completed within 48 h of hospital arrival were eligible for inclusion. Patients were excluded for a hospitalization >14 days, death within 24 h, severe alcohol withdrawal, prescribed cannabinoids, high daily opioid use prior-to-arrival, or transitioned to hospice or palliative care. Group assignments were determined based on the presence or absence of THC on the UDS. RESULTS: The analysis included 750 patients with 160 (21 %) THC positive patients. The population were primarily male (64.6 %), median age of 56 years [IQR 35-72], with blunt (93 %) injuries from motor vehicle crash or falls (79 %). The THC group was more likely to have other substances present, including amphetamines, benzodiazepines, opiates, and cocaine. The THC group had a higher median injury severity score (10 [IQR 5-17] vs. 9 [5-14], p = 0.0056), and maximum abbreviated injury score (3 [IQR 2-3] vs. 2 [IQR 2-3], p = 0.0009). The THC group had a total higher median opioid utilization during the hospitalization (155 [IQR 68-367] vs. 62 [IQR 13-175] MME; p < 0.0001), which included higher opioid use in the emergency department, floor, and intensive care unit. There were no significant differences in secondary outcomes except the THC group was more likely to receive an opioid prescription at discharge and more likely to require mechanical ventilation. Based on multivariable regression analyses, other variables were associated with increased opioid utilization. CONCLUSION: Pre-existing THC exposure may be associated with an increased hospital opioid utilization in a trauma population. However, other variables may also play a role in opioid utilization.

BACKGROUND: Fall-related injuries are a significant health issue that occur in 25% of older adults and account for a significant number of trauma-related hospitalizations. Although medication intensification may increase the risk of hospital readmissions in non-trauma patients, data on a geriatric trauma population are lacking. OBJECTIVE: The primary objective was to evaluate the effect of medication intensification on 30-day hospital readmissions in geriatric patients hospitalized for fall-related injuries. METHODS: This multicenter, retrospective cohort study included patients with geriatric who presented to one of three trauma centers within a large, health-system between January 1, 2018 and December 31, 2020. Patients at least 65 years old admitted with a fall-related injury were eligible for inclusion. Patients were grouped according to medication changes at discharge, which included intensified and non-intensified groups. Medication intensification included increased dose(s) or initiation of new agents. The primary outcome was the 30-day hospital readmission rate. RESULTS: Of the 870 patients included (median [interquartile range, IQR] age, 82 [74-89] years, 522 (60%) female, and 220 (25%) with a previous fall), there were 471 (54%) and 399 (46%) patients in the intensified and non-intensified groups, respectively. The intensified group had a higher 30-day hospital readmission rate (21% intensified vs. 16% non-intensified, p = 0.043; number needed to harm 20) based on an unweighted analysis. According to a weighted propensity score logistic regression, medication intensification was associated with higher 30-day hospital readmissions (24% [95% confidence interval [CI] 19-31%] intensified vs. 15% [95% CI 11-20%] non-intensified, p = 0.018). These results were consistent within competing risk models accounting for death (cause-specific model: hazard ratio [HR] 1.63 [95% CI 1.07-2.49], p = 0.023; Fine-Gray model: HR 1.64 [95% CI 1.07-2.50], p = 0.022). CONCLUSIONS: In a geriatric trauma population hospitalized after a fall, intensification of medications may pose an increased risk of 30-day hospital readmission.

Maternal mortality continues to be an issue globally despite advances in technology and pharmacotherapy. Pregnancy can lead to complications that necessitate immediate action to prevent severe morbidity and mortality. Patients may need escalation to the ICU setting for close monitoring and administration of advanced therapies not available elsewhere. Obstetric emergencies are rare but high-stakes events that require clinicians to have prompt identification and management. The purpose of this review is to describe complications of pregnancy and provide a focused resource of pharmacotherapy considerations that clinicians may encounter. For each disease state, the epidemiology, pathophysiology, and management are summarized. Brief descriptions of non-pharmacological (e.g., cesarean or vaginal delivery of the baby) interventions are provided. Mainstays of pharmacotherapy highlighted include oxytocin for obstetric hemorrhage, methotrexate for ectopic pregnancy, magnesium and antihypertensive agents for preeclampsia and eclampsia, eculizumab for atypical hemolytic uremic syndrome, corticosteroids, and immunosuppressive agents for thrombotic thrombocytopenic purpura, diuretics, metoprolol, and anticoagulation for peripartum cardiomyopathy, and pulmonary vasodilators for amniotic fluid embolism.

STUDY OBJECTIVE: The primary objective was to evaluate the performance of the Cockcroft-Gault (CG) equation with different body weights (BWs) compared to a measured creatinine clearance (mCrCl) in an intensive care unit (ICU) population with and without augmented renal clearance (ARC). DESIGN: Multicenter, retrospective cohort. SETTING: Two ICUs in the United States and four ICUs from a previous international observational analysis. PATIENTS: Adult ICU patients admitted from January 1, 2010 to July 30, 2020 with at least one mCrCl collected within the initial 10 days of hospitalization were eligible for inclusion. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the performance of the CG equation in ARC (mCrCl≥130 ml/min/1.73 m2 ) and non-ARC (mCrCl<130 ml/min/1.73 m2 ) patients. Correlation was analyzed by Pearson's correlation coefficient, bias by mean difference, and accuracy by the percentage of patients within 30% of the mCrCl. A total of 383 patients were included, which provided 1708 mCrCl values. The majority were male (n = 239, 62%), median age of 55 years [IQR 40-65] with a surgical diagnosis (n = 239, 77%). ARC was identified in 229 (60%) patients. The ARC group had lower Scr values (0.6 [0.5-0.7] vs. 0.7 [0.6-0.9] mg/dl, p < 0.001) and higher mCrCl (172.8 (SD 39.1) vs. 89.9 mL/min/1.73 m2 (SD 25.4), p < 0.001) compared with the non-ARC group, respectively. Among non-ARC patients there was a moderate correlation (r = 0.33-0.39), moderate accuracy (range 48-58%), and low bias (range of -12.9 to 17.1) among the different BW estimations with the adjusted BW having the better performance. Among ARC patients there was low correlation (r = 0.24-0.28), low to moderate accuracy (range 38-70%), and high bias (range of -58.5 to -21.6). CONCLUSIONS: The CG-adjusted BW had the best performance in the non-ARC patients, while CG performed poorly with any BW in ARC patients. Although the CG equation remains the standard equation for estimating CrCl in the ICU setting, a new, validated equation is needed for patients with ARC.

The response of ICU patients to continuously infused ketamine when it is used for analgesia and/or sedation remains poorly established. OBJECTIVES: To describe continuous infusion (CI) ketamine use in critically ill patients, including indications, dose and duration, adverse effects, patient outcomes, time in goal pain/sedation score range, exposure to analgesics/sedatives, and delirium. DESIGN SETTING AND PARTICIPANTS: Multicenter, retrospective, observational study from twenty-five diverse institutions in the United States. Patients receiving CI ketamine between January 2014 and December 2017. MAIN OUTCOMES AND MEASURES: Chart review evaluating institutional and patient demographics, ketamine indication, dose, administration, and adverse effects. Pain/sedation scores, cumulative doses of sedatives and analgesics, and delirium screenings in the 24 hours prior to ketamine were compared with those at 0-24 hours and 25-48 hours after. RESULTS: A total of 390 patients were included (median age, 54.5 yr; interquartile range, 39-65 yr; 61% males). Primary ICU types were medical (35.3%), surgical (23.3%), and trauma (17.7%). Most common indications were analgesia/sedation (n = 357, 91.5%). Starting doses were 0.2 mg/kg/hr (0.1-0.5 mg/kg/hr) and continued for 1.6 days (0.6-2.9 d). Hemodynamics in the first 4 hours after ketamine were variable (hypertension 24.0%, hypotension 23.5%, tachycardia 19.5%, bradycardia 2.3%); other adverse effects were minimal. Compared with 24 hours prior, there was a significant increase in proportion of time spent within goal pain score after ketamine initiation (24 hr prior: 68.9% [66.7-72.6%], 0-24 hr: 78.6% [74.3-82.5%], 25-48 hr: 80.3% [74.6-84.3%]; p < 0.001) and time spent within goal sedation score (24 hr prior: 57.1% [52.5-60.0%], 0-24 hr: 64.1% [60.7-67.2%], 25-48 hr: 68.9% [65.5-79.5%]; p < 0.001). There was also a significant reduction in IV morphine (mg) equivalents (24 hr prior: 120 [25-400], 0-24 hr: 118 [10-363], 25-48 hr: 80 [5-328]; p < 0.005), midazolam (mg) equivalents (24 hr prior: 11 [4-67], 0-24 hr: 6 [0-68], 25-48 hr: 3 [0-57]; p < 0.001), propofol (mg) (24 hr prior: 942 [223-4,018], 0-24 hr: 160 [0-2,776], 25-48 hr: 0 [0-1,859]; p < 0.001), and dexmedetomidine (µg) (24 hr prior: 1,025 [276-1,925], 0-24 hr: 285 [0-1,283], 25-48 hr: 0 [0-826]; p < 0.001). There was no difference in proportion of time spent positive for delirium (24 hr prior: 43.0% [17.0-47.0%], 0-24 hr: 39.5% [27.0-43.8%], 25-48 hr: 0% [0-43.7%]; p = 0.233). Limitations to these data include lack of a comparator group, potential for confounders and selection bias, and varying pain and sedation practices that may have changed since completion of the study. CONCLUSIONS AND RELEVANCE: There is variability in the use of CI ketamine. Hemodynamic instability was the most common adverse effect. In the 48 hours after ketamine initiation compared with the 24 hours prior, proportion of time spent in goal pain/sedation score range increased and exposure to other analgesics/sedatives decreased.
RESUMO
OBJECTIVE: Concise definitive review of the reinitiation of prior-to-admission neuropsychiatric medications (NPMs) in ICU patients. DATA SOURCES: Available literature on PubMed and MEDLINE databases. STUDY SELECTION: Available clinical trials and observational studies addressing the reinitiation of select NPMs (antidepressants, antipsychotics, and gabapentinoids) on various outcomes were included. DATA EXTRACTION: Eligible studies were identified by authors, and recommendations were summarized. DATA SYNTHESIS: Agitation and delirium are recognized as common complications of patients in the ICU. While there is literature that suggests patients can acutely withdraw from opioids, less data are known about withdrawal from NPM such as antidepressants, antipsychotics, and gabapentinoids. However, there is some literature that suggests reinitiating some NPMs may lead to reductions in agitation, delirium, and hospital and ICU length of stay. CONCLUSIONS: Additional larger studies are needed to evaluate the safety and efficacy of reinitiation of select prior-to-admission NPM to prevent agitation and delirium in ICU patients. Multiple factors for NPM reinitiation should be considered, such as reason for admission, organ dysfunction, available route of administration to provide prior-to-admission NPM, concomitant additional medications for agitation and delirium, and safety of these medications for patients in the ICU.

BACKGROUND: Propofol and dexmedetomidine may cause hemodynamic adverse effects (AEs) and more data are needed in a trauma and surgical population. OBJECTIVE: The objective of this study was to evaluate the rate of hemodynamic AEs requiring an intervention between dexmedetomidine and propofol in a critically ill trauma and surgical population. METHODS: This was a retrospective cohort study at a Level 1 trauma center. Intensive care unit patients admitted from October 1, 2017, through October 31, 2018, were divided into two groups: dexmedetomidine or propofol. The primary end point was the proportion of patients who required a therapeutic intervention for a hemodynamic AE within the first 24 hr of initiation of dexmedetomidine or propofol. RESULTS: A total of 800 charts were reviewed and 85 patients (dexmedetomidine [n = 35] and propofol [n = 50]) were included. The study population consisted of Caucasian (86%) males (61%) with a median age of 61 [interquartile range-IQR 48, 72], and 18% and 24% required antihypertensive and vasopressor agents, respectively. No difference in the primary outcome was observed (17 [49%] vs. 27 [54%], p = .624). There was no difference in the overall incidence of hemodynamic AE (18 [51%] vs. 30 [60%], p = .433). Dexmedetomidine patients had a greater decrease in median heart rate (HR) compared with the propofol (23 [IQR 16, 41] vs. 14 [IQR 5, 24] beats/min, p = .002). CONCLUSIONS: The rate of hemodynamic AEs requiring therapeutic interventions was similar between dexmedetomidine and propofol in a critically ill trauma and surgical population; however, dexmedetomidine may be associated with a larger decrease in HR.

BACKGROUND: Approximately 17% of intensive care unit (ICU) patients are prescribed at least 1 home neuropsychiatric medication (NPM). When abruptly discontinued, withdrawal symptoms may occur manifesting as agitation or delirium in the ICU setting. OBJECTIVE: To evaluate the impact of early reinitiation of NPMs. METHODS: This was a retrospective, observational cohort of adult ICU patients in a tertiary care hospital. Patients were included if admitted to the ICU and prescribed a NPM prior to arrival. Study groups were based on the timing of reinitiation of at least 50% of NPMs: ≤72 hours (early group) versus >72 hours (late group). RESULTS: The primary outcome was the proportion of patients with at least 1 agitation or delirium episode in the first 72 hours. Agitation and delirium were defined as at least 1 RASS assessment between +2 to +4 and a positive CAM-ICU assessment, respectively. A total of 300 patients were included, with 187 (62%) and 113 (38%) in the early and late groups, respectively. There was no difference in agitation or delirium (late 54 [48%] vs early 62 [33%]; adjusted odds ratio [aOR] = 1.5; 95% CI = 0.8-2.8; P = 0.193). Independent risk factors found to be associated with the primary outcome were restraints (aOR = 12.9; 95% CI = 6.9-24.0; P < 0.001) and benzodiazepines (BZDs; aOR = 2.0; 95% CI = 1.0-3.7; P = 0.038). CONCLUSIONS: After adjustment for baseline differences, there was no difference in agitation or delirium. Independent risk factors were restraint use and newly initiated BZDs.

Hypertensive emergencies (HTNe) primarily focus on decreasing the blood pressure to specific targets. However, there are emerging data surrounding the potential clinical effects of blood pressure variability (BPV) in patients with HTNe. This narrative review highlights the various definitions of BPV, the emerging role of BPV, and the clinical data surrounding BPV in the HTNe setting. Clinical studies were obtained from a PubMed search through October 2018 utilizing PICO methodology. Original research articles, systematic reviews, and meta-analyses were considered for inclusion. Articles were selected for inclusion based on the relevancy of the article investigating BPV in the HTNe setting. There is currently no accepted standard to express BPV in the acute care setting of HTNe, and various parameters have been reported. There are very limited data regarding BPV outside of the neurologic HTNe setting. In the acute treatment phase of neurologic HTNe, BPV is consistently associated with increased risk of unfavorable outcomes. In the HTNe setting, continuous infusion of calcium channel blockers may optimize BPV compared to other agents. Based on current data, BPV should be investigated in a prospective systemic fashion. Efforts should be taken to ensure that BPV is minimized in the acute phase of HTNe, especially for those patients with intracranial hemorrhage. This reduced BPV is associated with improved favorable outcomes, but further study investigating specific pharmacologic agents is needed.
