COVID-19 is an emerging disease all over the world and spreading at an unpredicted rate, resulting in significant influences on global economies and public health. Clinical, laboratory, and imaging characteristics have been partially described in some observational studies. Not enough systematic reviews on predictors of critical illness and mortality in COVID 19 have been published to date. In this review, we had illustrated the prognostic predictors of COVID-19 by gathering published information on the risk factors related to the outcomes of SARS-CoV-2 infections.
Deep accidental hypothermia (body temperature below 28 C) is rare. Even with modern supportive care of active external and internal rewarming techniques it is associated with a high mortality rate. We report the early and successful use of hemodialysis (HD) for active rewarming of a middle-aged alcoholic man with severe deep accidental hypothermia after failure of initial efforts of rewarming using conventional strategies. This case report and review of the literature highlights the advantages and the challenges of using HD in this setting and suggests a potential role for HD in the routine management of severe hypothermia in the absence of circulatory arrest.
Ethylene glycol poisoning is a common form of poisoning worldwide. The clinical course of ethylene glycol poisoning usually follows a three-stage progression, although these stages may overlap. A fourth stage of delayed neurological dysfunction consisting of cranial neuropathies has been suggested in several case reports. We describe a patient with unique findings of postural hypotension and gastroparesis following ethylene glycol toxicity with the additional uncommon features of albuminocytologic dissociation and increased intracranial pressure with papilledema. In addition, we provide a review of the literature on delayed neurological manifestations in ethylene glycol toxicity and further elucidate a description of a fourth stage of delayed neurological dysfunction following ethylene glycol poisoning.
Perioperative pain management for obese patients is daily challenges for anesthesiologists especially if complex comorbidities such as Obstructive Sleep Apnea and cardiovascular disease coexist. Limitations to effective pain management in this group are multifactorial, that includes technical difficulty with regional techniques, limited expertise, unavailability of standardized guidelines and lack of familiarity with recent multimodal analgesic regimens. Opioid-related complications such as narcotic-induced ventilatory depression in these group of patients poses another critical concern for both trainees and the experienced anesthesiologists. This chapter is intended for residents, fellows, as well as senior perioperative physicians, and will explore various regional and pharmacological options for acute pain management in this special population based on recent advances and available evidence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
