In this study, hypertonic saline infusion (experimental group ) and blood transfusion plus normal saline infusion (control group) were used for the treatment of uncontrolled hemorrhagic shock in dogs. The amount of blood loss from injured vessels are compared between two groups. Results: the amount of blood loss from injured vessels in shock stage were 35.2ml in the experimental group and 34.6ml in the control group, which showed no marked difference between two groups(Ｐ＞0.05).The amount of blood loss in resuscitation stage for experimental group was 15.10±1.52ml(early stage) and 14.00±1.37ml(late stage) and for control group was 14.20±1.52ml and 12.90±1.71ml respectively(Ｐ＞0.05).The amount of blood loss in resuscitation stage for both groups is much less than that in shock stage (Ｐlt;0.05).The results showed that infusion of hypertonic saline 30 min after uncontrolled shock is a safe and effective treatment which dose not cause further bleeding from the injured vessels. Clinical observation also confirmed the result.
Three different methods of electrocautery were used to study the effects of electrocoagu-lation on limbs and intraabdominal blood vessel of 6 rabbits. These methods are non-touching, touching and segmental electrocoagulation. The results show that all three methods can satisfactorily stop bleeding of the blood vessel which is smaller than 1. 5mm in diameter. For arteries with the diameter 1.5～2.0mm. the effect of segment electrocoagulation is better than the other methods because it has a long burn end after cautery.
