RESUMEN
<p><b>OBJECTIVE</b>To identify the risk factors for death in children with septic shock.</p><p><b>METHODS</b>Clinical data of 53 children with septic shock admitted to the Yuying Children's Hospital between January 2006 and July 2008 were retrospectively studied. Risk factors for death were assessed using univariate analysis and logistic regression analysis.</p><p><b>RESULTS</b>Nineteen cases died out of 53 children with septic shock. Univariate analysis and logistic regression analysis showed that arterial blood pH value<7.0 (OR=89.66), hypotension (OR=84.00), the pediatric critical illness score<70 (OR=60.00), the number of organ dysfunction>or=3 (OR=38.98), incompletion of volume resuscitation within 6 hrs after shock (OR=26.41), and no administration of effective antibiotics within 1 hr after shock (OR=11.43) and of vasoactive drugs (OR=75.68) were risk factors for death in children with septic shock.</p><p><b>CONCLUSIONS</b>A low arterial blood pH value (<7.0), hypotension, a pediatric critical illness score (<70) and the number of organ dysfunction>or=3 are related to a high mortality in children with septic shock. If the volume resuscitation can be completed within 6 hrs after shock, effective antibiotics can be administered within 1 hr after shock, and vasoactive drugs can be used properly, the outcome of children with septic shock may be improved.</p>

<p><b>OBJECTIVE</b>To recognize the clinical features of the enterovirus 71 (EV71) infection with pulmonary edema or pulmonary hemorrhage as a fulminant and often fatal illness.</p><p><b>METHODS</b>We retrospectively reviewed the medical records of the three cases with EV71 infection for clinical manifestation, laboratory data, medications, outcome etc.</p><p><b>RESULTS</b>All the cases were infants and they all died. These infants had no skin or mucosal lesions, however, they had sudden onset of cyanosis and tachypnea 1 to 2 days after the onset of the febrile disease with vomiting. All these 3 cases were misdiagnosed and were treated for shock on admission. Pulmonary hemorrhage was not considered in any of the cases on admission. All the cases received tracheal intubation when foamy secretions were discharged from mouth and nose of the patients and notable cyanosis was noted. After intubation, all had pink foamy fluid flew out from the endotracheal tube. The patients had hyperglycemia and limb weakness, two had tachycardia, and hypertension was found in one case. Chest X-ray showed bilateral or unilateral widespread air space opacity, but the cardiac size and shape were normal. All the patients had leucocytosis. EV71 infection was confirmed by detection of specific sequences of the virus in throat swab and tracheal secretions samples and in one case in cerebrospinal fluid sample.</p><p><b>CONCLUSION</b>Pulmonary edema or pulmonary hemorrhage occurred in the 3 cases with EV71-infected infants. The initial presentation was often nonspecific with fever and vomiting, and sudden appearances of cyanosis, tachypnea, tachycardia, hypertension or hypotension, limb weakness may suggest pulmonary edema or hemorrhage. Excessive fluid resuscitation may deteriorate the illness, on the contrary, fluid restriction and inotropic agents, and early intubation with positive pressure mechanical ventilation may be the proper treatment.</p>

<p><b>OBJECTIVE</b>This study sought to analyze the clinical manifestations and intervention of fulminant septic shock in community-acquired Pseudomonas aeruginosa septicemia.</p><p><b>METHODS</b>We retrospectively reviewed the medical records for diagnosis, antibiotic therapy, clinical course of septic shock, respiratory support, laboratory data etc.</p><p><b>RESULTS</b>Eight of nine cases with P. aeruginosa septic shock died. Fever (nine cases) and cough (three cases) or diarrhea (3 cases) were the 2 most common initial symptoms, three cases developed skin gangrenosum later. Pseudomonas aeruginosa infection was not considered in any of the cases before death or blood culture showed positive result. Only 3 cases were initially treated with susceptible antibiotic regimen but no anti pseudomonas combination therapy was applied, susceptible antibiotic monotherapy was applied in 7 cases after transfer to the ICU. The mean latency of shock occurrence was 5.1 hours (range 0 to 21 hours) after admission, the mean duration from the occurrence of shock to death was 13.8 hours (range, 1 - 32 hours). All the patients were transfer red to ICU for shock, the appropriate resuscitation of shock patients was delayed by 49.3 minutes (range 25 - 80 minutes) by transfer. Only two cases were diagnosed and treated for shock on admission; after transferred to ICU, only 5 patients were diagnosed as having shock, and only 3 received anti-shock treatment. Eight of the patients died of persistent shock. In 6 patients who died, mechanical ventilation was not applied until cardiac arrest occurred. All the patients had hypoalbuminaemia, elevated serum C-reactive protein concentration, leukopenia and 6 cases had DIC.</p><p><b>CONCLUSION</b>The initial presentation of the cases with community-acquired Pseudomonas aeruginosa septicemia was nonspecific with fever and cough or diarrhea. Clinicians often underestimated the severity of the infection, few patients received effective antimicrobial therapy. The authors suggest that an anti-pseudomonas antibiotic should be included in the initial empiric antibiotic regimen to cover P. aeruginosa high-risk patients; the front-line clinician should be educated for early recognition and aggressive resuscitation of P infection. aeruginosa septicemia.</p>

RESUMEN
Objective To explore the changes of plasma somatostatin(SST) in children with septic shock.Methods The level of plasma SST in children with septic shock (test group,n=21) on an empty stomach at shock stage,blood pressure and heart rate recovery stage,recovery stage(at that time clinical symptoms and signs disappeared,infection indicators such as blood routine and CRP returned to normal,about 6-12 days after admission) were detected by competive radioimmunassay,the level of SST in healthy children(healthy control group,n=25) on an empty stomach on morning was detected,too.The levels of plasma SST between septic shock concbined with paralytic ileus group and without paralytic ileus group were compared.Results 1.Level of plasma SST of test group at shock stage[(44.60?16.83) ng/L]was significantly lower than that of control group[(123.15?6.57) ng/L](t=-12.16 P0.05).The level of plasma SST of children with paralytic ileus [(28.10?7.0) ng/L] was significantly lower than that of children without paralytic ileus [(56.98?9.44) ng/L](t=-7.70 P
RESUMEN
Objective To explore the changes of serum gastrin(GAS),plasma motilin(MTL) and somatostatin(SST) in critically ill children with gastrointestinal dysfunction(GID).Methods According to pediatric critical illness score,75 cases were divided into greatly critical group(score90).Fifty cases of greatly critical and critical group were divided into GID group and non-GID group.The levels of serum GAS,plasma MTL and SST were detected on an empty stomach at acute stage and convalescence stage,comparing with those of normal control group,and then,the relationship between the levels of serum GAS,plasma MTL,SST and GID,the severity of disease were analyzed.Results At acute stage,the levels of serum GAS and plasma MTL of greatly critical group and critical group were higher than those of normal control group,the levels of plasma SST of greatly critical group and critical group were lower than that of normal control group,the more severe condition of critical children,the higher level of serum GAS and plasma MTL,the lower level of plasma SST.At convalescence stage,the level of serum GAS and plasma MTL of the greatly critical group and critical group decreased and the level of plasma SST increased.The levels of serum GAS and plasma MTL of GID group were higher than those of non-GID group,but the level of plasma SST of GID group was lower than that of non-GID group.Conclusion The level of serum GAS,plasma MTL and SST can be used to assess the severity of illness and prognosis,judge the change of disease and determine the efficacy of treatment programs,and detect gastrointestinal functional lesion.
