Ovariectomia videolaparoscópica ou convencional em cadelas: análise hemodinâmica, álgica e inflamatória

Abstract

The aim of this study was to compare two ovariectomy techniques (conventional vs laparoscopic) in bitches planning determine which procedure offers the lowest hemodynamic changes, painful stimuli, stress and inflammatory changes in trans and post-operative period. For the experiment were used 17 young mongrel bitches (12,58 ± 4,29 months), weighting 10.16 ± 0,69kg. Animals were placed into two groups according to the technique applied. In the first group (eight animals), ovariectomy (OV) was done by retro-umbilical celiotomy (GC) and in the second group (nine animals), by laparoscopy two-portal access (GV). For the assessment of analgesia were measured hemodynamic parameters (heart rate, respiratory rate, systolic arterial pressure, medium arterial pressure, diastolic arterial pressure, central venous pressure and cardiac output), and used three pain scales as follows: visual analogue (VAS), the University of Melbourne and the scale consists of Glasgow. To evaluate the stress and inflammatory changes were evaluated different parameters (C-reactive protein, cortisol, protein electrophoresis and acetylcholinesterase determination). In both procedures (GV and GC) there were no trans or post-operative complications. This study found that two-portal laparoscopic ovariectomy provides smaller and shorter pain stimuli that conventional ovariectomy when considering the following times and pain scales (two hours after surgery in Melbourne and the scale of 12 and 24 hours postoperative VAS), as well as in assessing the methods used to analyze the inflammatory response and stress, laparoscopic technique provided a lower elevation and a more rapid decline in the levels of C-reactive protein, mainly from six up to 72 hours after surgery, that the conventional technique.
