PREGNANCY DIAGNOSIS
Palpation of uterine swellings is possible by day 20 and easiest when they are of 3 cm diameter between days 28 and 32 and progressively more difficult after day 35 when individual swellings become less distinct from one another. The currently available assays for the pregnancy-specific placental hormone relaxin include Reprochek © ELISA quantitative assay and Witness Relaxin© immuno-migration qualitative slide test (both Synbiotics). Both are very accurate and definitive, since relaxin is not produced absent a pregnancy. The ELISA may detect relaxin as early as day 20-23 and the Witness test often detects pregnancy relaxin as early as day 26-30. False positives occur in cases of recent resorption or with retained placental tissue. False negatives as late as day 30 or 34 have been observed anecdotally, and negative results should be followed by U/S or re-assay one week later. U/S can detect pre-implantation vesicles by day 21 or earlier, embryonic masses by day 22-25, embryonic heart movement by day 24-27 using 5 or 7.5 MHz equipment.
3 laboratórios em Portugal realizam o ELISA.
Quanto á MELHOR injecção para terminar a gravidez, aqui estão os efeitos secundários:
5.4 Undesirable effects (frequency and seriousness)
In bitches treated after 20 days of gestation, abortion is accompanied by the physiological signs of parturition: fetal expulsion, vaginal discharge, reduced appetite, restlessness and mammary congestion. In field trials, 3.4 % of dogs suffered from uterine infections. After induced abortion with the product, an early return to oestrus is frequently observed (oestrus oestrus interval shortened by 1 to 3 months).
Side effects such as anorexia (25 %), excitation (23 %), depression (21 %), vomiting (2 %) and diarrhoea (13 %) have been reported from field trials.
In field trials, the administration of the product produced pain during and shortly after injection in 17 % of dogs and a local inflammatory reaction at the injection site in 23 % of dogs. The size and intensity of this reaction depended on the volume of the product which was administered. Oedema, skin thickening, local lymph node enlargement and ulceration may occur. All local reactions are reversible and will usually disappear within 28 days after injection.
In field trials, administration of the product induced haematological/biochemical changes in 4.5 % of dogs. These changes were always transient and reversible. The modified haematological parameters were as follows: neutrophilia, neutropaenia, thrombocytosis, haematocrit variation, lymphocytosis, lymphopaenia.
The modified (elevated) biochemical parameters were as follows: urea, creatinine, chloride, potassium, sodium, ALT, ALP, AST.
Por isso não existe nenhuma injecção TOTALMENTE SEGURA para terminar a gravidez.
Posto isto, na minha opinião, faria imediatamente o injectável, que tem que ser repetido após 24horas. Os dados são apenas para que perceba que sempre que fizer um aborto químico está efectivamente a prejudicar a cadela.
Abraço e boa sorte!
