OBJECTIVETo observe the effects of blood purification in the treatment of burn sepsis, in order to provide evidence for its application.

METHODSTwenty-seven patients with burn sepsis admitted to our burn ward from June 2012 to December 2013, conforming to the study criteria, were divided into conventional treatment group (CT, n = 15) and blood purification group (BP, n = 12) according to the random number table. After the diagnosis of sepsis was confirmed, patients in group CT received CT, while patients in group BP received both CT and continuous veno-venous hemodiafiltration for 48 hours. At the time of diagnosis of sepsis (before treatment) and post treatment hour (PTH) 24 and 48, levels of blood lactate and PaO2 were analyzed with blood gas analyzer, and the oxygenation index (OI) was calculated; blood sodium, blood glucose, blood urea nitrogen (BUN), creatinine, white blood cell count (WBC), procalcitonin (PCT) were determined; acute physiology and chronic health evaluation (APACHE) II score was estimated basing on the body temperature, respiratory rate, mean arterial pressure, PaO2, and blood pH values. The levels of TNF-α, IL-8, and IL-6 in serum were determined by ELISA. Data were processed with Fisher's exact test, t test, analysis of variance for repeated measurement, LSD- t test, and LSD test.

RESULTS(1) The levels of blood lactate of patients in group BP were significantly lower than those of group CT at PTH 24 and 48 (with t values respectively 1.62 and 2.44, P values below 0.05). Compared with that detected before treatment, the level of blood lactate in group BP was significantly decreased at PTH 48 (P < 0.05). The OI values of patients in group BP at PTH 24 and 48 [(247 ± 30), (288 ± 41) mmHg, 1 mmHg = 0.133 kPa] were significantly higher than those of group CT [(211 ± 32), (212 ± 30) mmHg, with t values respectively 3.02 and 5.63, P values below 0.01]. Compared with that detected before treatment, the OI values of patients in group BP at PTH 24 and 48 were significantly higher (P values below 0.01). (2) Compared with those of group CT at PTH 24 and 48, the levels of blood sodium, BUN, and creatinine were significantly lower (with t values from 1.74 to 6.75, P < 0.05 or P < 0.01), while the level of blood glucose was approximately the same (with t values respectively -0.92, -0.38, P values above 0.05) in group BP. Compared with those detected before treatment, the levels of blood sodium, BUN, and creatinine of group BP at PTH 24 and 48 were significantly lower (P < 0.05 or P < 0.01). (3) The levels of WBC and PCT of patients in group BP at PTH 24 and 48 were significantly lower than those of group CT (with t values from 2.11 to 6.63, P < 0.05 or P < 0.01). Compared with those detected before treatment, the levels of WBC and PCT of patients in group BP at PTH 24 and 48 were significantly lower (P < 0.05 or P < 0.01). (4) The APACHE II scores of patients in group BP at PTH 24 and 48 [(18.7 ± 2.6) and (16.7 ± 3.0) scores] were significantly lower than those of group CT [(23.1 ± 1.6) and (25.5 ± 1.6) scores, with t values respectively 5.44 and 9.87, P values below 0.01]. Compared with those calculated before treatment, the APACHE II scores of patients in group CT were significantly increased (P < 0.05 or P < 0.01), while those in group BP were decreased at PTH 24 and 48 (P < 0.05 or P < 0.01). (5) The levels of TNF-α, IL-6, and IL-8 in serum of patients in group BP at PTH 24 and 48 were significantly lower than those of group CT (with t values from 6.12 to 19.78, P values below 0.01). Compared with those detected before treatment, the levels of TNF-α, IL-6, and IL-8 in serum of group BP at PTH 24 and 48 were significantly decreased (with P values below 0.01).

CONCLUSIONSBP+CT is effective in improving organ function, correcting the disorder of internal environment, and controlling inflammation. Therefore, BP is an important method in the treatment of burn sepsis.

OBJECTIVETo explore the effects of oral administration of mixed enteral nutritional agent on intestinal mucosal barrier of patients with severe burn injury at early stage.

METHODSTwenty-four patients with severe burn injury admitted to our burn ward from August 2013 to September 2014, conforming to the study criteria, were divided into conventional therapy group (n = 12) and early enteral feeding group (n = 12) according to the random number table. Patients in conventional therapy group received conventional treatment immediately after admission, while those in early enteral feeding group were orally given 100 mL of a mixture of glutamine, probiotics, and prebiotics once a day besides conventional treatment for 7 days. Serum levels of diamine oxidase (DAO) and procalcitonin (PCT) and plasma level of LPS were determined by ELISA before treatment and on treatment day (TD) 1, 3, 7, 14, and 21. Wound secretion and blood samples were collected for bacterial culture within the 21 TD. The incidence of MODS within the 21 TD was observed. Data were processed with Fisher's exact test, rank sum test, analysis of variance for repeated measurement, and LSD-t test.

RESULTS(1) Serum levels of DAO in patients of early enteral feeding group on TD 7, 14, and 21 were respectively (14.9 ± 3.7), (12.4 ± 3.1), and (9.5 ± 0.7) ng/mL, which were significantly lower than those of conventional therapy group [(17.5 ± 4.0), (16.3 ± 3.3), and (13.0 ± 1.1) ng/mL, with t values from 2.913 to 15.304, P values below 0.01]. Serum levels of DAO at the other time points were close between the two groups (with t values from -0.598 to 0.139, P values above 0.05). (2) Compared with serum levels of PCT in patients of conventional therapy group [(11.7 ± 20.9) and (12.9 ± 23.9) ng/mL], those of early enteral feeding group were significantly lower on TD 7 and 14 [(2.7 ± 8.1) and (2.0 ± 5.6) ng/mL, with Z values respectively -2.919 and -2.139, P < 0.05 or P < 0.01]. Serum levels of PCT at the other time points were close between the two groups (with Z values from -1.833 to -0.346, P values above 0.05). (3) Plasma level of LPS in patients of early enteral feeding group on TD 7 was (33 ± 56) pg/mL, which was significantly lower than that of conventional therapy group [(102 ± 108) pg/mL, Z = -2.046, P < 0.05]. Plasma levels of LPS at the other time points between the two groups showed no significant difference (with Z values from -2.003~-0.526, P values above 0.05). (4) Positive results in bacterial culture of wound secretion were approximately the same between the two groups (P > 0.05). Bacterial culture of blood was positive in 7 patients of conventional therapy group and 1 patient of early enteral feeding group, showing significantly statistical difference (P < 0.05). MODS was observed in 1 patient of conventional therapy group, showing no significantly statistical difference with that of early enteral feeding group (no patient, P > 0.05).

CONCLUSIONSEarly intestinal feeding of mixed enteral nutritional agent in addition to conventional therapy can effectively promote repair of the impairment of intestinal mucosal barrier, protect integrity of intestinal mucosa, reduce damage to intestines, and alleviate inflammatory response in patients suffering from severe burn injury.

OBJECTIVETo evaluate the clinical implication of serum procalcitonin (PCT) in patients with burn sepsis by analyzing its change.

METHODSTwenty-eight extensively burned patients with sepsis hospitalized from January 2012 to December 2013 were recruited in this retrospective study. These patients were divided into death group (n = 12) and survival group (n = 16) according to the outcome. The baseline characteristics of patients in the two groups were similar. Some conventional indexes of sepsis, including white blood cell count, percentage of neutrophils, platelet count, organ function parameters [ALT, AST, total bile acid (TBA), creatinine, blood sodium], and acute physiology and chronic health evaluation (APACHE) II score were compared between the two groups when sepsis was diagnosed. Serum levels of PCT of patients in the two groups were determined immediately after diagnosis of sepsis, from post sepsis day (PSD) 1 to 4, and from PSD 5 to 8. Data were processed with t test, chi-square test, and nonparametric rank sum test (Keuskal-Wallis). Receiver operating characteristic (ROC) curve of serum PCT value was used to predict death for 28 burn patients when sepsis was diagnosed.

RESULTSThere were no statistically significant differences in white blood cell count, percentage of neutrophils, platelet count, APACHE II score, and organ function parameters between death group and survival group when sepsis was diagnosed (with t values from -0.601 to 1.726, P values above 0.05). The serum levels of PCT in death group immediately after diagnosis of sepsis, from PSD 1 to 4, and from PSD 5 to 8 were respectively (38.5 ± 41.3), (26.8 ± 38.5), (19.3 ± 16.3) ng/mL, which were significantly higher than those in survival group [(6.1 ± 2.3), (5.4 ± 2.9), (4.9 ± 3.6) ng/mL, with Z values from -4.364 to -2.955, P values below 0.01]. The total area under ROC curve of serum PCT value for predicting death for 28 patients with burn sepsis was 0.990, and 10.9 ng/mL was chosen as the optimal threshold value, with sensitivity of 91.7% and specificity of 100.0%.

CONCLUSIONSSerum PCT value can be served as a vital prognostic indicator for patients with burn sepsis, which can be considered as a guide for rational use of antibiotics, also provide as a reference for treatment, in order to reduce mortality.
