Methods The study was a prospective, observational pilot study Methods Nineteen juvenile female Hungahib pigs were subjected into conducted in our hospital. Consecutive adult patients with severe control group (n = 9) or septic group (n = 10). Under general anesthesia sepsis, on a mechanical ventilator with an IL-6 blood concentration in animals of the sepsis group, Escherichia coli culture (2.5 × 105/ml; ≥100 pg/ml in the acute phase, defi ned as being up to the 28th day of strain: ATCC 25922) was intravenously administrated in a continuously illness in the ICU, were entered in this study between June 2011 and increasing manner as follows: 2 ml in the fi rst 30 minutes, then 4 ml December 2012. Subjects were divided into those who were treated in 30 minutes and afterwards 16 ml/hour for 2 hours (so a total of with steroids (steroid treatment group) and those who were not (no- 9.5 × 106 E. coli within 3 hours).

In the no-steroids group, the bowel Results In the septic group, as expected, all animals developed sound counts were negatively correlated with IL-6 blood concentration fulminant sepsis and died within 3 to 7 hours two animals in 3 to 4 hours, (r = –0.76, P <0.01), suggesting that gastrointestinal motility was and three in 6 to 7 hours). In the septic animals the heart rate rose and suppressed as IL-6 blood concentration increased. However, in mean arterial pressure dropped, their ratio increased signifi cantly the steroid treatment group, gastrointestinal motility showed no compared with both the base values (at the 6th hour: P <0.001) and correlation with IL-6 blood concentration (r = –0.25, P = 0.27). The IL-6 the control group (P = 0.004). The control animals showed stable blood concentration appears to have decreased with steroid treatment condition over the 8-hour anesthesia. MCAV signifi cantly decreased irrespective of changes in the state of sepsis, whereas bowel sound during the development of sepsis (from 23.6 ± 6.6 cm/s to 16.0 ± 3.9 counts with the monitoring system refl ected the changes in the state cm/s, P <0.01) and pulsatility indices increased (from 0.68 ± 0.22 to of sepsis, resulting in no correlation. 1.37 ± 0.58, P <0.01), indicating vasoconstriction of the resistance Conclusion The new real-time bowel sound analysis system provides vessels.

Furthermore, to maintained cerebral autoregulation. this analysis may predict disease severity in septic patients. Conclusion Cerebral autoregulation is preserved in the pig model of experimentally induced fulminant sepsis.

The Sepsis Six [1] bundle Results Only 25/174 (14%) patients with a diagnosis of sepsis had an aims to optimise the fi rst hour of sepsis management. We assessed the EPR sepsis alert.
