ABSTRACT
Objective To explore the effect of lung water management guided by pulse indicator continuous cardiac output (PICCO) in noninvasive-invasive-noninvasive sequential mechanical ventilation to severe acute pancreatitis (SAP) caused acute respiratory distress syndrome (ARDS).Methods The patients with ARDS caused by SAP in the department of critical care medicine in this hospital from January 2012 to January 2015 were selected as the research subjects and divided into the treatment group (lung water management guided by PICCO) and control group(without lung water management guided by PIC CO) according to different lung water management modes.The noninvasive ventilation time,invasive ventilation time,total mechanical ventilation time,mortality rate,incidence rate of pulmonary edema,incidence rate of ventilator associated pneumonia (VAP) and ICU stay time were compared between the two groups.Results The invasive ventilation time in the treatment group was (3.54 ± 1.78)d,which was lower than (4.31 ±2.42)d in the control group(P＜0.05);the occurrence rate of pulmonary edema in the treatment group was 13.64 ％,which was lower than 35.42％ in the control group;the VAP occurrence rate in the treatment group was 6.82 ％,which was lower than 22.92％ in the control group;the mortality rate was 11.36％,which was lower than 29.17％ in the control group;the ICU stay time was (7.21 ± 1.13)d,which was lower than (8.19 ± 1.28)d in the control group,the differences were statistically significant(P＜0.05).Conclusion The lung water management guided by PICCO in SAP caused ARDS sequential mechanical ventilation is more accurate and effective,which is related to accurate liquid management,conduces to the patient's treatment,and is worthy of popularization and application.
ABSTRACT
Objective:To assess whether Veronicastrum axillare (V. axillare) can ameliorate ethanol-induced gastric mucosal lesions in rats, reduce the production of pro-inflammatory cytokines, suppress apoptosis and improve local microcirculation disturbances. Methods:Totally 48 male Sprague-Dawley rats were randomly divided into six groups, eight rats in each group. Rats in the normal group and the model group were administered with 0.9%normal saline respectively. Rats in the positive group and ranitidine group were administered with 0.18% ranitidine suspension by intragastric administration respectively. Those in the high dose V. axillare group, the medium dose V. axillare group and the low dose V. axillare group were administrated with V. axillare at the daily dose of 2.8 g/kg, 1.4 g/kg and 0.7 g/kg by intragastric administration. Gastric mucosal lesions were produced by intragastric administration of absolute ethanol. Water extract of V. axillare was successively injected for 14 d and last day was injected 1 h before ethanol administration. Gastric mucosal ulcer index and ulcer inhibitory rate were counted by improved Guth methods. The tissue sections were made for pathological histology analysis. Also, we measured the concentrations of tumor necrosis factor-α (TNF-α) and endothelin-1 (ET-1) in gastric mucosal, as an index of the pro-inflammatory cytokines, apoptosis and local microcirculation. Besides, the mRNA contents of TNF-αand ET-1 were measured to verify effects on gene expression by real-time fluorescent quantitative PCR. Results: Water extract of V. axillare significantly ameliorated the gastric mucosal lesions induced by ethanol administration (P Conclusion: Current evidences show water extract of V. axillare is effective for defending against ethanol-induced gastric mucosal lesions, significantly inhibiting the production of pro-inflammatory cytokines and the expressions of TNF-αand ET-1 mRNA, which may be useful for inhibiting apoptosis and improving local microcirculation.
