Abstract :

Treatment of diffuse peritonitis remains a challenge. With the advent of vacuum therapy, the use of laparostomy has gained attraction. However maintaining a peritoneal lavage is difficult and has controversial results. In this experiment we developed a new model of continuous peritoneal lavage taking advantage of the features of the vacuum laparostomy. Eight pigs were submitted to laparotomy through which a multi- perforated tube was placed along flanks and exteriorised in the lower quadrants. A vacuum dressing was placed and negative pressure was maintained. The pigs were divided into 2 groups: A group of four animals received a Peritoneal Dialysis Solution (PDS) and the other group received Saline Solution (SS). To asses the system's efficiency in reach abdominal spaces and recesses, solution with carbon particles in suspension diluted was infused into the abdominal cavity in all pigs, this was followed by computerized tomography images. To evaluate the efficiency of the intra-abdominal fluid clearance, an espectophotometry analysis of carbon particles were performed. Computerized tomography after fluid infusion showed that this method is able to occupy all intra-abdominal spaces and recesses. It should also an appropriate clearance of abdominal fluid with progressive removal of carbon particles . Dressing integrity was not compromised. There were no leaks or blockage. Almost solution infused was reabsorbed. Hemodynamic and biochemical parameters remained within normal limits when DS was used. This was not achieved with SS. This model of continuous peritoneal lavage is technically feasible, maintain physiological parameters within the normal range when PDS is used.
