Answer: Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen. In animal cells anaerobic respiration often occurs during exercise. The glucose does not get fully broken down in this process, so it does not release its full potential energy. Instead of carbon dioxide and water it breaks down to form lactic acid and a small amount of energy.

Duration of hypotension before initiation of effective antimicrobial therapy is the critical determinant of survival in human se
nydimaria [60]

The goal is to find out how often effective antimicrobial therapy is delayed after the start of persistent or recurrent hypotension in septic shock and how this affects mortality.

Design: A cohort research that was conducted in retrospect between July 1989 and June 2004.

Setting: Ten hospitals (four academic, six community) and fourteen critical care units (four medical, four surgical, and six combined medical/surgical) located in Canada and the United States.

Patients: The 2,731 adult patients with septic shock listed in their medical records.

Measurements and key findings: Survival to hospital discharge served as the primary outcome indicator. A survival percentage of 79.9% was found when an antibiotic efficacious for isolated or suspected infections was administered within the first hour of verified hypotension. Over the following 6 hours, each hour of antibiotic delivery delay was linked to an average 7.6% decline in survival. When compared to obtaining treatment within the first hour after the beginning of persistent or recurrent hypotension, the in-hospital mortality rate was considerably higher by the second hour (odds ratio 1.67; 95% confidence range, 1.12-2.48). The single best predictor of outcome in multivariate analysis (which included Acute Physiology and Chronic Health Evaluation II score and treatment factors) was time to the start of effective antimicrobial therapy. It took 6 hours on average to start effective antimicrobial therapy (25-75th percentile, 2.0-15.0 hrs).

Conclusions: In adult patients with septic shock, effective antibiotic therapy during the first hour of confirmed hypotension was related with enhanced survival to hospital discharge. Only 50% of patients with septic shock got efficient antimicrobial therapy within 6 hours of being diagnosed with proven hypotension, despite a steady rise in fatality rate with increasing delays.

<h3>What is septic shock?</h3>

Which applies to an earthworm but not to a hydra?
kow [346]
I think the hydra lacks the specialized cells for touch and chemical detection. On the other hand earthworms have touch, light, vibration and chemical receptors along the entire body surface. Both of them are invertebrates (those animals without a backbone), they include insects, worms, jelly fish, spiders among other animals.
