Abstract

SILVA, Alcino Lázaro da et al. Experimental study in rats of the effect, on the posterior abdominal wall, of washing the abdominal cavity with 0,9% saline heated at different temperatures. Acta Cir. Bras. [online]. 2001, vol.16, n.1, pp. 52-55. ISSN 1678-2674.  http://dx.doi.org/10.1590/S0102-86502001000100008.

The washes of the abdominal cavity with 0,9% salt solution is a very common procedure in General Surgery. In general it doesn't exist an adequate temperature control, being sometimes introduced in the abdominal cavity the saline solution at high temperature, which may possibly cause cell injury. The aim of this work is to study the posterior wall abdominal cavity cell of mice, after it is treated with 0,9% salt solution heated at different degrees. We used 28 mice divided into 3 groups with 9 animals in each group and one as the control mouse. The group A was treated with 0,9% salt solution at 37ºC, the group B at 45ºC and group C at 60ºC. The control mouse wasn't treated with 0,9% salt solution. In all groups the 0,9% salt solution stayed in the abdominal cavity for 1 minute. Histopatologic exam revealed in the control mouse and group A and B the muscle fibers and cellular estriations was intact. In the group C, meanwhile observed principles of cellular degeneration. Concluding the importance of effective temperature control of 0,9% salt solution to be introduce in mice abdominal cavity must be emphasized to prevent thermal injury in cells.
