Pain Assessment and Acute Phase Response in Donkeys Submitted to Inguinal Orchiectomy.

This study investigates the effects of pain management in donkeys undergoing an orchiectomy procedure through an inguinal approach. By assessing behavioral cues, physiological changes, and acute phase proteins, the researchers aim to improve techniques and care around these common surgical procedures.

Research Design and Methodology:

The research involved a sample of 15 male donkeys, maintained under extensive management conditions. The selected donkeys have a mean age of approximately 4.5 years. As part of the study, all selected donkeys underwent an orchiectomy procedure through an inguinal route. Prior to the surgery, anesthesia was applied to the donkeys including dissociative anesthesia and a local block with lidocaine.

• Various factors such as behavior indicative of pain, hematological characteristics, Acute Phase Proteins (APP) levels, and the condition of the surgical wound were consistently evaluated at 0, 24, 48, and 72 hours postoperatively.
• Besides the study focused on finding variations in physiological parameters and APP measurements at different times. The use of nonsteroidal antiinflammatory drugs helped to control significant fluctuations in these parameters.
• The macroscopic evaluation was performed to identify any significant changes in the surgical wounds across different time intervals.
• The severity of pain was gauged using a scale that categorized pain levels between 2 and 3, indicating mild to moderate pain and determining if any intervention was required.

Key Findings:

The study concluded with several key observations which could affect future treatment protocols,

• The research found that most animals experienced only mild or moderate edema in the scrotum and foreskin regions after the operation. The average inflammation scores of the animals did not show significant variation by time, with mean scores narrowly ranging from 1.6 to 1.8.
• Regarding pain, the average scores were between the crowd range of 2 and 3, equating to mild and moderate pain. The pain levels detected didn’t require direct intervention, according to the study.

Implications:

Though the research provided valuable insights into post-operative care for donkeys undergoing orchiectomy via an inguinal approach, further investigation is suggested by the researchers.

• The behavior of PFAs (Plasma Fibrinogen Aggregation) under varying variables is one area the researchers singled out for future studies.
• The development of new animal pain scales specifically for extensively managed animals is proposed as another avenue for in-depth investigation.
