ABSTRACT
Objective:To select the animal model more consistent with the pathophysiology of abdominal compartment syndrome (ACS) through the comparative study of the methods of multiple water sacs superimposed compression and gas perfusion.Methods:Ten experimental pigs were randomly divided into two groups ( n = 5): the "constant volume model" (constant volume model group) and the "constant pressure model" (constant pressure model group) of intra-abdominal hypertension. The models were prepared by the method of water sac superposition and pressurization, and artificial pneumoperitoneum respectively. The abdominal pressures of both groups were 25 mmHg (1 mmHg = 0.133 kPa) and observed for 4 hours. The pressure was measured once an hour for 4 hours and the pressure-time curves of the two groups were drawn respectively. The experimental animals were sacrificed 4 hours after modeling. The heart and lung were harvested, and the histopathological changes were observed by hematoxylin-eosin (HE) staining. Results:Two groups of experimental pigs were successfully modeled. The abdominal pressure gradually increased at 0, 1, 2, 3, 4 hours after operation in the constant volume model group (mmHg: 25.0±0, 27.1±0.2, 29.4±0.1, 30.9±0.2, 33.1±0.1), and there was a positive correlation between the abdominal pressure and time (functional equation: Y1 = 25.102 0+1.996 0 X1; R2 = 0.996 2, P = 0.000 1). The abdominal pressure value in the constant pressure model group at 0, 1, 2, 3, 4 hours were maintained 25 mmHg, and there was no linear correlation between the abdominal pressure and time (functional equation: Y2 = 25). HE staining showed that in the constant volume model group, the myocardial fibers were accompanied with hyaline degeneration, significantly reduced transverse lines, part of myocardial fiber atrophy, and visible nuclear aggregation; hemorrhage, chronic inflammatory cell infiltration and inflammatory exudation were found in the lung tissues. In the constant pressure model group, partial atrophy of myocardial fiber, partial hypertrophy, focal hyaline degeneration, disappearance of local striae, hyaline degeneration of myocardial fiber, dilation and congestion of intermyocardial artery were observed. Slight hyperplasia of alveolar epithelium in some areas, heart failure cells, dilation and congestion of bronchi and trachea artery, a large number of red blood cells and uniform light staining substances in lumen were found. Conclusion:After the model was made by the method of multiple water sacs, the pressure of the abdominal cavity continued to increase with the development of the disease, which was in line with the clinical pathological changes of ACS, and was more suitable for making the animal model of the intra-abdominal hypertension.

ABSTRACT
Objective To investigate the effectiveness and safety of applying compound lidocaine cream on tracheal mucosa as topical anesthesia to reduce the stress reaction during extubation of tracheal tube. Methods Sixty patients (aged 18-65yr,body weight 40-80kg,ASA Ⅰ-Ⅱ) scheduled for elective surgery under general anesthesia were selected,and they were randomly divided into compound lidocaine cream group (group L,n=30) and control group (group C,n=30). Orotracheal intubation was performed in all the patients. Compound lidocaine cream was uniformly smeared on the foremost third of endotracheal tubes before intubation in group L,and no drug was coated on endotracheal tubes in group C. The changes in blood pressure and heart rates during extubation,the use of hypotensive drugs,cough reflex,breath holding,sore throat and pharyngeal discomfort after extubation were compared between the two groups. Results The operation and intubation time of the two groups showed no significant difference. The blood pressure and heart rate during extubation,the rate of using hypotensive drugs,and the incidence of cough reflex and breath holding were lower in group L than in group C,while the foreign body sensation in pharynx were after extubation was more frequent in group L than in group C. The incidence of pharyngodynia was similar in the two groups,and the pharyngodynia and foreign body sensation in pharynx markedly improved one day after operation in both groups. Conclusion Topical anesthesia of tracheal mucosa using compound lidocaine cream may reduce the cough reflex and breath holding during extubation,and inhibit the stress reaction.
