[Microcirculation changes of three -meridians of hand in the forearm in rabbits with arrhythmia: a comparative study].

OBJECTIVE

To observe the microcirculation changes of three -meridians of hand in the forearm in rabbits with arrhythmia, and to compare the differences of responses among the three -meridians of hand.

METHODS

A total of 20 New Zealand rabbits were randomly divided into a saline group and a model group, 10 rabbits in each one. The rabbits were anesthetized with intravenous injection of 20% ethyl carbamate (3.3 mL/kg) at ear vein; the saline group was injected with 0.9% sodium chloride solution (1 mL/kg), while the model group was injected with 0.4% barium chloride solution (1 mL/kg) to establish the arrhythmia model. The microcirculation changes of the three -meridians of hand were observed and analyzed by laser speckle blood flow imaging technique before and after the intervention.

RESULTS

Compared before modeling, the microcirculation perfusion of the three -meridians of hand in the model group was significantly reduced (<0.01), and the reduction in the meridian was more significant than that in the meridian (<0.05), but there was no significant difference between the meridian and meridian (>0.05). There was a negative correlation between microcirculation perfusion and position (<0.001), indicating the closer to the elbow, the more the microcirculation perfusion decreased.

CONCLUSION

During arrhythmia in rabbits, the dysfunction of and blood existes in the three -meridians of hand in the forearm, particularly the meridian. In addition, the closer to the elbow, the more obvious the reaction of the three -meridians of hand is.
