The outcomes of large-volume IVF administration to septic shock patients with comorbid congestive heart failure (CHF) and/or end-stage renal disease (ESRD) are uncertain and widely debated in the existing literature. Despite this uncertainty, CMS continues to recommend that 30 ml/kg of an intravenous crystalloid solution be administered to patients in septic shock starting within 3 h of presentation. We performed a systematic review and meta-analysis to assess the relationship between adherence to this guideline and outcomes among patients whose underlying comorbidities present a risk of fluid overload. ⋯ Among septic shock patients with CHF and/or ESRD, administration of greater than or equal to 30 ml/kg IVF was associated with a non-significant increase in odds of mortality. All other outcomes measured were found to be non-significant, although there was a trend toward better outcomes among patients in the restricted-volume compared to the standard-volume IVF groups. Since this meta-analysis only included five observational studies, more studies are needed to guide an optimal volume and rate of fluid administration in this patient population.

Case Reports
Neurologic toxicity of carbamazepine in treatment of trigeminal neuralgia: A case report.
Carbamazepine is a medication used to treat a variety of neurological and psychiatric conditions including seizure disorders, neuropathic pain syndromes, and bipolar disorder. Unfortunately, its pharmacokinetics and side effect profile may lead to significant toxicities due to its sodium channel blockade. ⋯ In this article, we describe a case of a 40-year-old female who presented to a local emergency department with focal neurological deficits after repeated supratherapeutic dosing of carbamazepine.. This case highlights a key cerebrovascular accident mimic that emergency physicians should consider from acute toxicity that can be seen with carbamazepine in a patient who was taking the medication as prescribed.

Caffeine poisoning is relatively rare, and a near-fatal caffeine overdose is highly uncommon. We present an 18-year-old male who attempted suicide with 295 mg/kg pure caffeine powder (lethal oral dose: 150-200 mg/kg) and was successfully rescued. ⋯ Then, hemodialysis ultimately eliminated serum caffeine and completely alleviated caffeine-related central nervous system toxicity. We discuss the clinical symptoms, management and toxicodynamics based on the concentration of caffeine and its metabolites in serum and urine.
