Aims:
The aim of this study was to evaluate the effects of early rapid control of multiple bowel perforations on cardiovascular function in combined abdominal missile trauma and haemorrhagic shock compared with conventional surgery.
Methods:
Eighteen anesthetised pigs were injured with a standardised abdominal missile trauma. The animals were bled to a mean arterial pressure of 50 mm Hg for 30 minutes, after which they were resuscitated and had laparotomy. They were divided into conventional surgery group (n=9) with primary resection and anastomosis of bowel -injuries and early rapid multiple bowel ligation group (n?=?9). Repeated measurement analysis of variance was used for analysis.
Results:
There was profound hypotension, reduced cardiac output, increased vascular resistance and lactic acidaemia in both groups. Lactic acidaemia persisted longer in the early rapid multiple bowel ligation group. There were no significant differences in mean arterial pressure, cardiac output , stroke volume or systemic vascular resistance between the groups. The mean operation time was significantly shorter in the early rapid multiple bowel ligation group (13.3 (1.5) (SEM) minutes, compared with 116.4 (1.74) (SEM) minutes in the conventional surgery group, p =0.001).
Conclusions:
Damage control principles have shortened the operating time in our model but did not improve the cardiovascular function and caused more lactic acidaemia than conventional repair.
