Sepsis & Low BP

Nicholas Simpson, Francois Lamontagne, Manu Shankar-Hari
PURPOSE OF REVIEW: We reviewed the recent advances in the initial approach to resuscitation of sepsis and septic shock patients. RECENT FINDINGS: Sepsis and septic shock are life-threatening emergencies. Two key interventions in the first hour include timely antibiotic therapy and resuscitation. Before any laboratory results, the need for resuscitation is considered if a patient with suspected infection has low blood pressure (BP) or impaired peripheral circulation found at clinical examination...

BACKGROUND: Sepsis plays an important role in acute gastrointestinal injury (AGI). Our research was designed to determine the effects of omega-3 fish oil (FO) in patients suffering from severe sepsis combined with AGI III, and the ability of FO to modulate immune function. METHODS: Seventy-eight patients diagnosed with severe sepsis with AGI III and a need for mechanical ventilation were randomized to two groups. In the FO group, 50 g of long chain fatty acid soybean oil (n = 6) and 10 g of FO (n = 3) were administered as total parenteral nutrition (TPN)...

BACKGROUND: Hypoglycemia in a critical care setting is often multifactorial with iatrogenic insulin use, sulfonylurea (SU) use, sepsis, adrenal insufficiency and insulinoma among the common causes. Insulin autoimmune syndrome (IAS) is a rare cause of hypoglycemia characterized by the presence of insulin-binding autoantibodies to the sulfhydryl group-containing agents. We report a case of methimazole-induced IAS managed in the intensive care unit. CASE PRESENTATION: A 76-year-old woman with a history of primary hyperthyroidism was sent from a nursing home for unresponsiveness...

BACKGROUND: There are limited data on the safety of colonoscopy in patients with lower gastrointestinal bleeding (LGIB). We examined the various adverse events associated with colonoscopy in acute LGIB compared with non-GIB patients. METHODS: Emergency hospitalized LGIB patients (n = 161) and age- and gender-matched non-GIB controls (n = 161) were selected. Primary outcomes were any adverse events during preparation and colonoscopy procedure. Secondary outcomes were five bowel preparation-related adverse events--hypotension, systolic blood pressure <100 mmHg, volume overload, vomiting, aspiration pneumonia and loss of consciousness--and four colonoscopy-related adverse events--including hypotension, perforation, cerebrocardiovascular events and sepsis...

Vasopressor support is used widely for maintaining vital organ perfusion pressure in septic shock, with implications for dynamic cerebral autoregulation (dCA). This study investigated whether a noradrenaline-induced steady state increase in mean arterial blood pressure (MAP) would enhance dCA following lipopolysaccharide (LPS) infusion, a human-experimental model of the systemic inflammatory response during early sepsis. The dCA in eight healthy males was examined prior to and during an intended noradrenaline-induced MAP increase of approximately 30 mmHg...

Hereditary hemorrhagic telangiectasia (HHT) is mechanistically and therapeutically challenging, not only because of the molecular and cellular perturbations that generate vascular abnormalities, but also the modifications to circulatory physiology that result, and are likely to exacerbate vascular injury. First, most HHT patients have visceral arteriovenous malformations (AVMs). Significant visceral AVMs reduce the systemic vascular resistance: supra-normal cardiac outputs are required to maintain arterial blood pressure, and may result in significant pulmonary venous hypertension...

INTRODUCTION: Liberal and overaggressive use of vasopressors during the initial period of shock resuscitation may compromise organ perfusion and worsen outcome. When transiently applying the concept of permissive hypotension, it would be helpful to know at which arterial blood pressure terminal cardiovascular collapse occurs. METHODS: In this retrospective cohort study, we aimed to identify the arterial blood pressure associated with terminal cardiovascular collapse in 140 patients who died in the intensive care unit while being invasively monitored...

BACKGROUND AND OBJECTIVES: Sepsis during pregnancy is a rare complication. This potentially fatal disease often occurs due to maternal infectious and can lead to fetal loss. Therefore, any attempted treatment must be aimed at the mother’s well being. As a matter of fact, there are few recent medical publications about sepsis in pregnancy. In spite of this, the treatment based on Surviving Sepsis Campaign seems suitable and practical. The aim of this article is making a case report highlighting a very well succeeded treatment of a pregnant woman with urinary sepsis...

An understanding of heart-circulation interaction is crucial to our ability to guide our patients through an episode of septic shock. Our knowledge has advanced greatly in the last one hundred years. There are, however, certain empirical phenomena that may lead us to question the wisdom of our prevailing treatment algorithm. Three extreme but iatrogenically possible haemodynamic states exist. Firstly, inappropriately low venous return; secondly, overzealous arteriolar constriction; and finally, misguided inotropy and chronotropy...

INTRODUCTION: Nitric oxide (NO) influences susceptibility to infection and hemodynamic failure (HF) in sepsis. NOS3 and NOS2 SNPs might modify plasma nitrite/nitrate (NOx) levels, sepsis development, hemodynamics and survival. METHODS: 90 severely septic and 91 non-infected ICU patients were prospectively studied. NOS3 (E298D), NOS3 (-786 T/C), NOS3 (27 bp-VNTR), and NOS2A (exon 22) SNPs and plasma NOx levels were assessed. RESULTS: 21 patients (11...
