[The use of a beta 2-mimetic agent (clenbuterol) in equine pregnancy disorders and obstetrics].

The research paper discusses a study investigating the impact of a drug called Clenbuterol on mares experiencing pregnancy complications or problems during the period around parturition.

Objective of the Research

• The research primarily aims to understand the effects of Clenbuterol, a beta 2-mimetic agent, on mares dealing with pregnancy disorders or complications during the periparturient period, which refers to the time immediately before, during, and after parturition (birth).

Methodology

• The study involved 34 participating mares.
• An initial dose of 0.3 mg of Clenbuterol was administered intravenously.
• Follow up doses or extended treatment was based on the individual’s evolving condition during dystocia (difficult labor), medical indications for treatment, and their clinical pre-parturient status.

Key Concepts

• Clenbuterol, a beta 2-mimetic agent, works by relaxing the muscles around the bronchial tubes, aiding in breathing. In the context of this study, it was used to induce tocolysis (relaxation of the uterus) in pregnant mares.
• Dorsoflexio uteri ante partum refers to the bending or flexing of the uterus towards the dorsal (back) side before parturition.
• Abortus imminens describes a condition in which there is a threat of miscarriage, a serious pregnancy complication.
• Preparturient labor pains are the pains experienced by the mare before the initiation of parturition.

Outcomes

• The results of the study are not explicitly mentioned in the abstract, but the primary aim appears to be understanding whether Clenbuterol can effectively manage or treat equine pregnancy disorders and complications in the periparturient period.
