Effects of Hemorrhagic Shock on the Flow and Electrophoretic Pattern of Protein of Thoracic Duct Lymph

Abstract
|
|
|
Several investigators demonstrated that hemorrhagic shock produced a increase in the flow of thoracic duct lymph. However, the detailed analysis of their results revealed the lack of unanimity in the pattern of increase in the flow of thoracic duct lymph. On the other hand, the proposed role of thoracic duct lymph as a protein reservoir in shock has not been well established.
This study was undertaken to investigate the effects of hemorrhagic shock Ion the flow and the electrophoretic pattern of protein of thoracic duct lymph in anesthetized dogs whose blood pressure was lowered and maintained at the level of 60-70 mmHg for four hours.
The following results were obtained:
1. Following the production of hemorrhagic shock the flow of thoracic duct lymph was very slightly decreased transiently. Thereafter the flow gradually returned to a rate of pre-hemorrhage level. However, there was noted a considerable individual variety.
2. Transfusion or electrolyte infusion which was administered four hours after induction of hemorrhagic shock produced a marked increase in the flow of duct lymph and it was more prominent following the infusion of electrolyte solution.
3. During the course of shock total protein and its fractions of thoracic duct lymph and serum showed no remarkable change.
4. Following the infusion of electrolyte solution the concentration of lymph protein was slightly decreased, whereas the lymph flow was markedly increased. Therefore, the total return of protein to systemic circulation through the duct was probably unchanged.
