[Correlation between the area of arterial blood gases graph and the acid-base disturbance in 92 cases with chronic obstructive pulmonary disease].

Objective: To study the correlation between the area of arterial blood gases graph (ABGG) and the acid-base disturbance (ABD).

Methods: Using the software developed by ourselves, the results of arterial blood gases and concomitant electrolyte (K(+), Na(+), Cl(-), HCO(3)(-)) determination in 313 episodes were analyzed in 92 cases with chronic obstructive pulmonary diseases (COPD) during hospitalization, and the correlation was studied.

Results: (1)On admission, among 92 cases, in 9 cases the results of blood gas analysis were in the area of compensated ventilation and deranged gas exchange (area IV), in 82 cases the results were in the area of insufficient ventilation and deranged gas exchange (area V), and 1 case in the area of excessive ventilation and deranged gas exchange (area VI).

[Alterations in myocardial function in early stage of sepsis in rabbits].

Objective: To study the alterations in myocardial function in early stage of sepsis.

Methods: Twenty rabbits were randomly divided into two groups. In the control group (n=10) only laparotomy was done, and in the sepsis group the animals received cecal ligation and puncture (CLP).
