Use of a wireless system to measure invasive arterial blood pressure in ponies – preliminary study.

The research article evaluates the use of a wireless system for measuring invasive arterial blood pressure in ponies, examining its practicality, reliability, and any short-term complications that may arise. The results indicate that the wireless method allows for continuous monitoring, possibly even in situations where conventional methods fall short.

Methods and Subjects

• The study was a prospective preliminary research conducted using five adult, mixed breed, intact male ponies. The average weight of the ponies was 104 +/- 28.8 kg.
• The researchers carried out surgery on these ponies and implanted an intra-arterial wireless device in the right carotid artery of each pony.
• In addition to the implant, a transcutaneous intra-arterial catheter was inserted in each pony’s left facial artery on the next day.
• The arterial blood pressure data from the ponies were continuously collected after the surgical procedures had been completed.
• Post-mortem examinations were also performed to gain more insights into the impacts of the implantation surgery.

Results and Complications

• On average, the surgery time taken for implantation of the device was 27.1 +/- 11.85 minutes.
• Complications arising post-implantation were pretty minor, consisting primarily of mild seroma and hematoma. Seroma is the accumulation of serous fluid in a pocket under the skin, while hematoma is a localized bleeding outside of blood vessels.
• All catheters remained in place despite minor shifts in positioning outside the vascular system.

Conclusion

• The study concluded that the wireless system could allow for continuous monitoring of invasive arterial blood pressure in ponies, both during rest and throughout anesthesia.
• This system might allow for more convenient and consistent recording of arterial blood pressure and heart rate when it would be tough to achieve with a conventional system, such as during a pony’s recovery from anesthesia.
• The wireless blood pressure monitor may allow for continuous measurements in circumstances when only sporadic measurements would be possible with a wired system.
