RESUMEN
OBJECTIVE: To evaluate the occurrence of severe sepsis and septic shock and the rate of compliance with sepsis bundle in patients with severe sepsis and septic shock in emergency department. METHODS: A prospective study was conducted on consecutive adult patients who were sent to Emergency Department of Ruijin Hospital, Shanghai Jiaotong University School of Medicine by ambulance from May to June in 2009. The occurrence of severe sepsis and septic shock, and the number of the patients in whom who met the criteria of compliance with sepsis bundle were analyzed. RESULTS: Nine hundred and seventeen patients who were sent to the emergency department by ambulance in that period were enrolled in the study. The number of patients with severe sepsis and septic shock was 96. The incidence of severe sepsis and septic shock was 10.47%. Among these patients, the number of patients in whom the sepsis bundle was complied, i.e. sepsis bundle, appropriate cultures were taken before antimicrobial therapy, placement of central venous catheter and monitoring of central venous pressure (CVP) as well as central venous oxygen saturation (ScvO2) within 2 hours, antibiotic therapy within 3 hours, early goal directed therapy (EGDT) within 6 hours, and lactate clearance in 12 hours reached 1.04%, 3.12%, 2.08%, 83.33%, 1.04%, 23.96%. The Results were 1.19%, 3.57%, 2.38%, 83.33%, 1.19%, 26.19% and 0, 0, 0, 83.33%, 0, 8.33% in medical and surgical emergency department respectively. There was no statistical difference between the two divisions (all P>0.05). CONCLUSION: The incidence of severe sepsis and septic shock was high in emergency department, but the rate of recognition of it and the compliance with sepsis bundle were inadequate. It is urgently necessary to enhance the learning and implementation of the guideline.

AIM: Irritable bowel syndrome (IBS) is characterized by abdominal pain and changes in stool habits. Visceral hypersensitivity is a key factor in the pathophysiology of IBS. The aim of this study was to examine the effect of rectal balloon-distention stimulus by blood oxygenation level-dependent functional magnetic resonance imaging (BOLD-fMRI) in visceral pain center and to compare the distribution, extent, and intensity of activated areas between IBS patients and normal controls. METHODS: Twenty-six patients with IBS and eleven normal controls were tested for rectal sensation, and the subjective pain intensity at 90 ml and 120 ml rectal balloon-distention was reported by using Visual Analogue Scale. Then, BOLD-fMRI was performed at 30 ml, 60 ml, 90 ml, and 120 ml rectal balloon-distention in all subjects. RESULTS: Rectal distention stimulation increased the activity of anterior cingulate cortex (35/37), insular cortex (37/37), prefrontal cortex (37/37), and thalamus (35/37) in most cases. At 120 ml of rectal balloon-distention, the activation area and percentage change in MR signal intensity of the regions of interest (ROI) at IC, PFC, and THAL were significantly greater in patients with IBS than that in controls. Score of pain sensation at 90 ml and 120 ml rectal balloon-distention was significantly higher in patients with IBS than that in controls. CONCLUSION: Using fMRI, some patients with IBS can be detected having visceral hypersensitivity in response to painful rectal balloon-distention. fMRI is an objective brain imaging technique to measure the change in regional cerebral activation more precisely. In this study, IC and PFC of the IBS patients were the major loci of the CNS processing of visceral perception.
