Objectives:
To assess the evidence and discuss the risks and clinical relevance of ketamine for the treatment of various disease states impacting the adult critically ill population.
Data Sources:
A literature review was performed using PubMed evaluating primary literature published until August 2018.
Study Selection:
Case reports, observational studies (cohort, case-control), and randomized controlled trials involving patients 18 years and older in a nonperioperative setting using either IV or intramuscular ketamine were included for analysis. Uses of ketamine discussed focused on critically ill patients in the ICU and emergency department settings.
Data Extraction:
Included studies were evaluated for dosing, outcomes, and adverse effects of ketamine. For each study, the design, population, intervention, investigated outcomes, and results were assessed.
Data Synthesis:
The evidence was organized according to use of ketamine, which included pain, sedation, status asthmaticus, alcohol withdrawal syndrome, status epilepticus, and acute behavioral psychologic disturbances. Evaluation of the evidence was based on the included primary literature along with any related guideline recommendations.
Conclusions:
Ketamine has suggested potential benefit in several disease states impacting critically ill patients including pain, alcohol withdrawal syndrome, status epilepticus, and acute agitation. Further supporting evidence is needed to validate its use in the setting of critical illness.
IntroductionLittle is known regarding age-related risk of nephrotoxicity during vancomycin therapy after the publication of the 2009 vancomycin consensus guidelines for therapeutic drug monitoring. We sought to evaluate incidence and risk factors for acute kidney injury in three age groups.MethodsMatched cohort study of patients receiving vancomycin, grouped by age: young adults (18–64 years), older adults (65–79 years) and very elderly (≥80 years), matched on previously published risk factors for nephrotoxicity. Outcomes included traditional vancomycin nephrotoxicity and Acute Kidney Injury Network-modified definition of nephrotoxicity.ResultsThe incidence of acute kidney injury was 34.1% vs. 34.1% vs. 31.8% in the young, older adults and very elderly groups, respectively (p = 0.97). In the logistic regression model, after adjusting for baseline risk factors, age was not a significant predictor of acute kidney injury. Lower respiratory tract infection (adjusted odds ratio [aOR] 5.18; 95% confidence interval [CI] 2.15–12.41) and duration of treatment (aOR 1.12; 95% CI 1.03–1.22) were found to be independently associated with outcome.ConclusionNo differences in risk of acute kidney injury were identified between young, older, and very elderly adults when adjusting for other risk factors. Further research is required to identify strategies to optimize the safety of vancomycin in the aging population.Electronic supplementary materialThe online version of this article (doi:10.1007/s40121-013-0022-6) contains supplementary material, which is available to authorized users.
LBA294 Background: AGOC has limited options after second-line therapy. Regorafenib (Rego), an oral multi-targeted tyrosine kinase inhibitor (TKI) targeting angiogenic, stromal and oncogenic receptor TKs, prolonged progression free survival (PFS) versus placebo (PBO) across all regions/subgroups in the INTEGRATE phase 2 randomised trial (JCO 2016 43(23):2728-2735). INTEGRATE IIa was designed to examine if Rego improves overall survival (OS). Methods: Double-blind placebo-controlled phase 3 trial comparing Rego + best supportive care (BSC) vs PBO + BSC using 2:1 randomisation, stratified by tumour location (GO junction vs gastric), geographic region (Asia vs rest of world), prior VEGF inhibitors (Y/N). Eligibility criteria: histologically/cytologically confirmed AGOC, evaluable metastatic/locally advanced disease, failure/intolerance of ≥ 2 prior lines of therapy with a platinum agent + fluoropyrimidine. Primary objective: OS in the whole study population. OS among Asian sub-population is a key secondary objective. Target of at least 221 events from 250 patients provides 80% power to detect an OS hazard ratio (HR) of 0.67. Pooled OS analysis incorporating INTEGRATE phase 2 data is also planned. Secondary endpoints include PFS, objective response rate, safety and quality of life. Results: 251 patients enrolled (Oct16 - Sep21) from 5 countries:157 from Asia (Korea, Taiwan, Japan);169 Rego and 82 PBO. After 238 events, median OS (in months) for Rego vs PBO was 4.5 vs 4.0 (HR 0.70 [95%CI: 0.53 to 0.92]; p = 0.011) in the whole study population, with a 12 mo survival of 19% vs 6%. Median PFS was 1.8 v 1.6 (HR = 0.52; [95%CI: 0.40-0.69]; p = < .0001). After pre-planned adjustment for multiplicity, there were no statistically significant differences across regions (Asia versus non-Asia) or other pre-specified subgroups. Pooled analysis median OS was 5.0 v 4.1 (HR 0.69 [95% CI:0.56 to 0.87]; p = 0.001). Rego toxicity was similar to previously reported. Conclusions: Rego improves survival compared with PBO in advanced refractory AGOC, offering a new treatment option. This result creates a therapeutic platform for combination studies. INTEGRATE IIb is an ongoing international randomised Phase 3 trial in pre-treated patients with AGOC comparing Rego + nivolumab to standard chemotherapy (NCT0487936). Clinical trial information: NCT02773524 .
The popularity of recreational synthetic drug use has increased within the past several years. Emergency physicians, along with prehospital providers, are often the first to interact with patients who use these new drugs. We report the case of a 27-year-old male with two emergency department visits with confirmed ingestion of a relatively new synthetic drug of abuse. We discuss symptom management as well as the identification process of the ingestant.
