Background: The angiogenic induction property of the omentum makes it a promising pedicle for prefabricating flaps. Therefore, the objective of this paper is to establish the abdominal area to be prefabricated by the omental pedicle and to analyse the prefabricated potential (PP) according to the time delay between the pedicle introduction and the flap release.
Methods: Forty-four rabbits were divided into four groups (A, B, C and D).
Background And Purpose: Carbon dioxide pneumoperitoneum is associated with significant hypercarbia and acidosis. The aim of this study is to evaluate the effects of carbon dioxide and helium pneumoperitoneum on renal function.
Materials And Methods: Thirty adult dogs were put randomly into one of three groups (n=10 animals each): group A--pneumoperitoneum not performed; group B--CO(2) pneumoperitoneum; and group C--helium pneumoperitoneum.
Background And Purpose: Mechanical and hormonal factors have been implicated in pneumoperitoneum-induced renal alterations. The aim of this study was to evaluate the effects of enalaprilat (Vasotec) administration on renal function during CO2 pneumoperitoneum, given that this drug, which is an angiotensin-converting enzyme inhibitor, by inhibiting the renin-angiotensin-aldosterone system, alters hormone-induced changes during pneumoperitoneum.
Materials And Methods: Thirty adult dogs were randomly assigned to one of three groups (N = 10 each): group A (pneumoperitoneum not performed); group B (CO2 + enalaprilat); group C CO2 only.
