“…Durante a anestesia, o decúbito dorsal lateralizado para esquerda ou para direita atenua os efeitos da compressão da veia cava (Alef, 2017). Quando posicionada em decúbito dorsal, a veia cava e a artéria aorta ficam comprimidas, diminuindo o retorno venoso e, consequentemente, diminuindo a frequência cardíaca e a pressão arterial (Conti et al, 2013;Morais, 2011;Silva et al, 2015;Taylor, 1997).…”

A seleção do protocolo anestésico e dos medicamentos administrados em pacientes prenhas deve primordialmente zelar pela segurança tanto da mãe quanto dos fetos, uma vez que não é viável realizar uma anestesia seletiva na cadela sem comprometer o bem-estar fetal. Esse trabalho objetivou relatar o manejo anestésico e o restabelecimento da pressão arterial sistêmica de uma paciente canina frente a um quadro hipotensivo durante uma cesariana. Foram empregados fármacos em doses reduzidas com o objetivo de elevar a pressão arterial materna e minimizar a depressão fetal resultante da passagem desses medicamentos pela barreira transplacentária.

“…As importantes alterações fisiológicas que ocorrem durante a prenhez envolve os sistemas respiratório, renal, hepático e cardiovascular e devem ser levados em consideração (Taylor, 1997). Durante o período gestacional, a frequência cardíaca e o volume sistólico podem aumentar de 30 a 50%.…”

“…5 As maternal stress directly and negatively affects the fetus, physiological and environmental stressors have different effects depending on the stage of gestation, with exposure early in gestation potentially affecting embryogenesis and organogenesis and later exposure causing metabolic and endocrine disturbances possibly affecting parturition. 25 Stage of gestation was excluded in our multivariable analysis likely due to overparameterization and sample size.…”

Objective: To evaluate, following colic admission during pregnancy, (1) broodmare survival; (2) the frequency of recurrent colic in broodmares and its associated variables, and (3) pregnancy outcome and the variables associated with a negative pregnancy outcome.Study design: Ambidirectional observational cohort study. Animals: One hundred and four client-owned broodmare admissions.Methods: Admissions of pregnant mares from June 2010 until October 2016 were included. Data were collected until November 2017. Cox proportional hazards regression analysis was performed to evaluate variables associated with broodmare survival. Logistic regression analysis was used to examine the variables associated with recurrent colic and pregnancy outcome.Results: Broodmares from 73/104 (70.2%) admissions were discharged alive. Lesion category, admission hyperlactatemia (hazard ratio (HR) 3.24, 95%, CI 1.28-8.22, P = .013), and admission high packed cell volume (HR 2.89, 95% CI 1.29-6.47, P = .010) were associated with reduced survival. Recurrent colic was observed in broodmares from 33/70 admissions (47.1%). The final multivariable model for recurrent colic included Thoroughbred breed (OR 5.09, 95% CI 1.58-16.4, P = .006) and age (OR .876, 95% CI .747-1.03, P = .105). Overall, negative pregnancy outcome was 14/65 (21.5%). Lesion category, evidence of systemic inflammatory response syndrome (SIRS) in hospital (OR 31.2, 95% CI 2.09-466.5, P = .013), and diarrhea in hospital (OR 379.3, 95% CI 97.1-1482.0, P < .001) were associated with increased negative pregnancy outcome. Altrenogest administration was inversely associated with negative pregnancy outcome (OR 0.029, 95% CI .004-.222, P = .001). Conclusion:Pregnant broodmares admitted for colic had lower survival than anticipated and were at risk of recurrent colic. Markers of broodmare disease severity were associated with pregnancy outcome. Clinical significance: Lesion category, hematologic variables (packed cell volume and L-lactate concentration), evidence of SIRS, and diarrhea were useful for predicting broodmare and pregnancy outcomes.

“…Conditions which produce endotoxins or increased levels of prostaglandin, or cause endocrine imbalances, may result in abortion or have deleterious effects on fetal development through the passage of substances across the placenta or by causing disturbances in blood flow on either side of the uterine/placental interface. Anaesthesia is a high risk procedure in the pregnant mare and may cause periods of fetal hypoxia (Taylor 1997).…”
