Objective To evaluate the renal cortical blood perfusion changes in rabbits with acute renal failure (ARF) with gray scale contrast-enhanced ultrasound, and to explore the relationship between these changes and the blood creatinine (SCr), as well as the blood urea nitrogen (BUN). Methods Rabbit ARF models were established with 50% glycerin injected into the rabbits' thighs. Gray scale contrast-enhanced ultrasound was performed on the day before injection (T_0) and 1, 4, 8, 12 days (T_1, T_4, T_8, T_(12)) after injection. The renal cortex perfusion time-intensity curve (TIC) was analyzed, including parameters like arrival time (AT), time to peak intensity (TTP), amplitude of peak intensity (A) and slope rate of TIC (β) of renal cortex. Meanwhile the SCr and BUN were measured, the correlation between SCr, BUN and parameters were analyzed. Results Compared with the value of T_0, the value of TTP, A, β after injection (T_1, T_4, T_8) were statistically different, respectively (P<0.05), but the differences among T_1, T_4 and T_8 were various. No linear correlation between above parameters and SCr, BUN was found. Conclusion The renal cortical blood perfusion changes can be early observed with gray scale contrast-enhanced ultrasound, but there is no linear correlation between the changes of parameters and SCr, BUN.

Objective To assess the application of contrast-enhanced ultrasound (CEUS) in evaluation of the renal cortical and medullary perfusion changes before and after acute renal failure (ARF) in rabbits. Methods Rabbit ARF models were established with intramuscular 50% glycerin (12-15 ml/kg) injection into rabbits' thighs. One day before and after ARF models establishment, CEUS was performed on each rabbit. The renal perfusion time-intensity curve (TIC) was analyzed, including parameters like AT (arrival time), TTP (time to peak intensity), A (amplitude of peak intensity), AUC (area under the curve), β (slope rate of TIC) of renal cortex and medulla. Results The value of A and β before model establishment was (17.36±13.73) dB and (5.38±2.08) dB/s, respectively, both was significantly higher than those after glycerin injection ([6.59±4.25] dB and [1.58±1.41] dB/s, respectively) (P<0.05). The value of TTP and AUC before model establishment was (2.46±1.76) s and (329.31±171.70) dBs, both was significantly lower than those after injection ([5.93±4.80] s and [722.28±354.14] dBs, respectively) (P<0.05). No significant difference was found in AT of renal cortex and AT, A, TTP, AUC, β of renal medulla, nor in SCr or BUN. Conclusion CEUS can display the changes of perfusion image of the renal cortex of the ARF earlier than SCr and BUN.

ObjectiveTo investigate the safety and efficacy of carbon dioxide ( CO2 ) insufflation during ERCP.MethodsBetween January and August 2011,a total of 102 consecutive patients who underwent ERCP were randomized to accept CO2 insufflation ( n =52 ) of air insufflation ( n =50 ) during the procedure.ERCP was carried out with the same instrument by an expert endoscopist who was blinded to the insufflation gas used and the procedure was controlled at 30 minutes to 1 hour.The heart rate,oxygen saturation of the patient was continuously monitored during the procedure.Before the procedure and 1 hour after the end of operation,abdominal X-ray was taken to evaluate the width of intestine,and the degree of intestinal expansion was defined as normal,mild,moderate and severe according to the width increased.A questionnaire with 100 mm visual analogue scale (VAS) was used to quantify the abdominal pain and distention experienced at 1 hour,2 hours,and 6 hours after the procedure.The patients' vital signs,bowel dilatation,the average operating time,abdominal pain score and distention score on VAS,and complications in 2 groups were analyzed.ResultsThe baseline characteristics of 2 groups were comparable.ERCP was successfully performed in all the patients and no complication was observed.In CO2 group,the average operating time,mean heart rate and oxygen saturation were (45.2 ± 10.6) min,( 102.2 ± 10.3 ) bpm and ( 99.5 ± 0.5)%,which were (48.5 ± 11.2) min,( 100.3 ± 11.4) bpm and (98.9 ±0.6)%,respectively,in air group.There were no significant differences on these items between the 2 groups ( P > 0.05 ).Moderate to severe intestinal expansion 1 hour after ERCP was found in 14 patients (26.9% ) in CO2 group and in 28 patients (56.0% ) in air group,and the latter was significantly higher than the former (x2 =11.61,P =0.009).Both of the mean abdominal pain and abdominal distention scores at 1 hour post-ERCP in CO2 group were lower than those in air group,but without significant difference (P >0.05).However,the mean abdominal pain scores at 2 hours and 6 hours post-ERCP in CO2 group were significantly lower than those of patients in air group (7.4 ±2.2 vs.18.7 ±4.6 at 2 hours post-ERCP,9.6 ±3.7 vs.20.1 ±4.5 at 6 hours post-ERCP,all P < 0.05 ).Similarly,the mean abdominal distention scores at 2 hours and 6 hours post-ERCP in CO2 group were significant lower than those of patients in air group (7.6 ±3.6 vs.18.3 ±4.1 at 2 hours post-ERCP,8.9 ±3.7 vs.19.4 ±4.2 at 6 hours post-ERCP,all P <0.05).ConclusionThe use of CO2 insufflation instead of air during ERCP appears to be safe.Insufflation of CO2 during ERCP palliates the intestinal expansion,post-ERCP abdominal pain and distention comparison to insufflation of air.However,because of the single-center clinical observation with limited number of cases,the safety and efficacy of CO2insufflation during ERCP requires to be further evaluated.
