Objective To study the bacterial types and their drug resistance in intra-abdominal infections after pancreatic surgery,and to evaluate the appropriate treatment measures.Methods 113 patients who underwent pancreatic surgery from Jan 2012 to Dec 2012 in our hospital were included into this study.The drainage liquid from the surgical sites were collected for bacterial culture and drug susceptibility tests.Results The incidence of intra-abdominal infections was 39.8％ (45/113).There were 54 pathogenic strains of bacteria isolated,including 49 strains of gram-negative bacteria (90.7％),4 strains of gram-positive bacteria (7.4％),and 1 strain of fungus (1.9％).The top three pathogens were Pseudomonas aeruginosa (50.0％),Acinetobacter baumannii (14.8％) and Singular deformation bacteria (1 1.1％).Most gram-negative bacteria were sensitive to Polymyxin B and Aminoglycoside antibiotics (＞ 70％),but they were resistant to Imipenem and Cephalosporin which were commonly administered.Pancreatic fistula was closely related to intra-abdominal infections.Concluusions A gram-negative bacteria,Pseudomonas aeruginosa,was the predominant organism in intra-abdominal infections after pancreatic surgery in our hospital.The situation of drug-resistance was still severe.More effective measures should be taken to prevent growth of resistant strains such as using antibiotics according to drug sensitivity and avoiding empirical single use of broad-spectrum antibiotics.Pancreatic fistula commonly led to intra-abdominal infections.

Objective To investigate the clinical value of dynamic glucose monitoring in the middle and late pregnant women with diabetes mellitus,and the related clinical and nursing measures.Methods One hundred admitting cases of the middle and late pregnant women with diabetes mellitus were grouped according to the random number table,50 cases of the control group were treated with finger tip blood glucose monitoring and conventional treatment,50 cases of dynamic blood glucose monitoring and comprehensive clinical and nursing intervention for the observation group.The blood glucose control situation with different time,the incidence of hypoglycemia,the actual control range of the glycosylated hemoglobinblood and the length of hospital stay and so on were evaluated in two groups.Results The incidence of hypoglycemia in the observation group was 6.0％ (3/50),the control group was 24.0％ (12/50),the difference was statistically significant (P ＜ 0.05).In the early morning,after breakfast 2 h,before and after lunch 2 h,before and after dinner 2 h and before bed and other different time,the blood glucose level with the observation group was lower than that in the control group (P ＜ 0.05).At the same time,in the blood glucose effective controlling time,hospitalization time,the observation group was better than the control group (P ＜ 0.05).The blood glucose level and the detection range of the glycosylated hemoglobin were also detected in the safe state for outpatient follow-up after hospital discharge.Conclusions The intervention of dynamic blood glucose monitoring and comprehensive clinical and nursing measures in middle and late pregnant women with diabetes mellitus is conducive to control blood glucose level timely and accurately and to improve their prognosis.It is the key to the success of the future obstetric prevention and diagnosis and treatment of the disease,and is recommended clinical popularization.

The therapeutic effects of intensive insulin therapy in treatment of traumatic shock combined with multiple organ dysfunction syndrome (MODS) were investigated. A total of 114 patients with traumatic shock combined with MODS were randomly divided into two groups: control group (n=56) treated with conventional therapy, and intensive insulin therapy group (n=58) treated with conventional therapy plus continuous insulin pumping to control the blood glucose level at range of 4.4-6.1 mmol/L. White blood cells (WBC) counts, prothrombin time (PT), serum creatinine (SCr), alanine aminotransferase (ALT), serum albumin and PaO(2) were measured before and at the day 1, 3, 5, 7 and 14 after treatment. The incidence of gastrointestinal dysfunction, the incidence of MODS, hospital stay and the mortality were also observed and compared. After intensive insulin therapy, the WBC counts, SCr, ALT and PT were significantly reduced (P<0.05), but the level of serum albumin was significantly increased (P<0.05) at the day 3, 5, 7 and 14. In the meantime, the PaO2 was significantly elevated at the day 3, 5 and 7 (P<0.01) after intensive insulin therapy. The incidence of gastrointestinal dysfunction, the incidence of MODS, the length of hospital stay and the mortality were markedly decreased (P<0.01). The results suggest early treatment with intensive insulin therapy is effective for traumatic shock combined with MODS and can decrease the length of hospital stay and the mortality.
