A Controlled Study in CPR-Survival in Propensity Score Matched Full-Code and Do-Not-Resuscitate ICU Patients.

BACKGROUND: Cardiopulmonary Resuscitation (CPR) causes significant injuries and increased cost among transiently resuscitated patients that do not survive their hospitalizations. Descriptive studies show zero and near-zero percent survival for CPR recipients with high Apache II scores. Despite these factors, no controlled studies exist in CPR to guide patient selection for CPR candidacy. Our objective was therefore to perform a controlled study in CPR to inform recommendations for CPR candidacy. We hypothesize that the protective effects of CPR decrease as illness severity increases, and that Full-Code status provides no survival benefit over Do-Not-Resuscitate (DNR) status for patients with the highest predicted mortality by Apache IV score. METHODS: We performed propensity-score matched survival analyses between Full-Code and DNR patients after stratifying by predicted mortality quartiles using Apache IV scores. Primary outcomes were mortality hazard ratios. Secondary outcomes were Median Survival Differences, ICU LOS, and tracheostomy rates. RESULTS: Among 17,710 propensity-score matched ICU encounters, DNR status was associated with greater mortality in the first through third predicted mortality quartiles. There was no difference in survival outcomes in the fourth quartile (HR 0.99, p = .96). There was a stepwise decrease in the mortality hazard ratio for DNR patients as quartiles increased. CONCLUSION: Full-Code status provides no survival benefit over DNR status in individuals with greater than 75% predicted mortality by Apache IV score. There is a stepwise decrease in survival benefit for Full-Code patients as predicted mortality increases. We propose that it is reasonable to consider a very high predicted mortality by Apache IV score a contraindication to CPR given the lack of survival benefit seen in these patients. Larger studies with similar methods should be performed to reinforce or refute these findings.

Extubation of the difficult airway.

Managing the airway in the intensive care unit (ICU) is complicated by a wide array of physiologic factors. Difficult airway may be a consequence of patient's anatomy or airway edema developed during the ICU stay and mechanical ventilation. The incidence of failed airways and of cardiac arrest related to airway instrumentation in the ICU is much higher than that of elective intubations performed in the operating room. In this article, we will provide a framework for identifying a difficult airway, criteria for safe extubation, as well as review the devices that are available for airway management in the ICU. Proficiency in identifying a potentially difficult airway and thorough familiarity with strategies and techniques of securing the airway are necessary for safe practice of critical care medicine

Pancreatitis associated with Strongyloides stercoralis infection in a patient chronically treated with corticosteroids.

Strongyloides stercoralis is a nematode that is a ubiquitous parasite in man. Life-threatening infections can occur in immunocompromised patients. We report a case of a 64-year-old Puerto Rican gentleman treated chronically with corticosteroids for reactive airway disease, who presented to our institution with pancreatitis complicated by sepsis and acute lung injury requiring mechanical ventilation. The initial working diagnosis was gallstone pancreatitis; however, several days into his hospital course, he was found to have a history of strongyloidiasis. Subsequent examination of his stool revealed the parasite, and the patient was treated with ivermectin. This case highlights the occasional association between pancreatitis and strongyloidiasis and the importance of proper treatment and consideration of infection in patients from endemic regions, which include Central America, Africa, and Asia.
