Topic:Obstetrics
Obstetrics in horses involves the study and management of reproduction, pregnancy, and parturition in equine species. This field encompasses the physiological processes of conception, gestation, and foaling, as well as the identification and treatment of reproductive disorders. Key aspects include understanding the mare's reproductive cycle, monitoring fetal development, and managing the birthing process to ensure the health and well-being of both the mare and the foal. Research in equine obstetrics often focuses on improving reproductive efficiency, diagnosing and addressing complications such as dystocia, and enhancing neonatal care. This page compiles peer-reviewed research studies and scholarly articles that explore various facets of equine obstetrics, including reproductive physiology, prenatal care, and foaling management.
[Morbidity and mortality of mare and foal following dystocia – a literature review]. Dystocia represents a life-threatening condition for mare and foal. Morbidity and mortality rates due to a difficult birth, as well as the influence on fertility of the mare were analyzed, based on a review of publications. This was aggravated by the fact that no standardized diagnostic code was used and that most publications do not clearly describe how extensively the examinations were performed beforehand. Retentio secundinarum is the most common complication caused by dystocia. Other complications are injuries to the soft birth canal and the colon. These occur more frequently after surgica...
Postpartum Polyneuropathy in a Mare: A Case Report. Obstetric paralysis is a generic term used to describe postpartum locomotor alterations resulting from nerve damage, widely reported in cattle, but rare in equines. The aim of this study is to report a case of a peripheral polyneuropathy in a primiparous mare, 3 years old, of Mangalarga Marchador breed, after a dystocia lasting approximately 12 hours. At the time of delivery, the head of the fetus was exposed in the vulva and there was flexion of the thoracic limbs. These events culminated in a framework of extreme abduction of the pelvic limbs, thus generating functional impotence and leadin...
Developing a 3D animation tool to improve veterinary undergraduate understanding of obstetrical problems in horses. Many challenges are encountered in both teaching and learning veterinary obstetrics. This may be due to outdated teaching materials, as the main model of content transmission remains centred around text and images. Methods: Visualisation methods such as three-dimensional (3D) and Graphics Interchange Format (GIF) tools were applied in an attempt to improve obstetrics education outcomes in the third-year class. Traditional teaching methods were utilised in the fourth-year and fifth-year students. Results: These supplementary tools significantly increased the third-year students' final examinati...
A case report on the use of guaifenesin-ketamine-xylazine anesthesia for equine dystocia. In 4 mares suffering from dystocia, general anesthesia was induced with xylazine (1.1 mg/kg, IV) and ketamine (2.2 mg/kg, IV) and maintained with continuous intravenous infusion of ketamine (2 mg/ml), xylazine (0.5 mg/ml) and guaifenesin (50 mg/ml) in 1 L of 5% dextrose. The duration of the procedure of these mares were 40, 45, 180, and 35 minutes, respectively. For procedures required more than 1 hour (Mare 3), the dose of ketamine and xylazine in the mixture was reduced to 1 mg/ml and 0.25 mg/ml, respectively. Average infusion rate of the mixture used to maintain anesthesia for each mare was...
[The use of a beta 2-mimetic agent (clenbuterol) in equine pregnancy disorders and obstetrics]. A clinical study about the effects of a beta 2-mimetic agent (Clenbuterol) in mares with pregnancy disorders or disorders during the periparturient period (n = 34) is reported. In general, a single dose of 0.3 mg Clenbuterol given i.v. induces sufficient tocolysis. Subsequent doses or follow-up treatment depend upon individual development during dystocia, indication of treatment and clinical preparturient status (dorsoflexio uteri ante partum, abortus imminens, preparturient labor pains).
