Incisional Pain Models
Post-operative pain management is a major challenge for clinicians and patients. Unrelieved post-operative pain management causes patient suffering and discomfort, and can promote psychological and pathophysiological obstacles (Castel et al., 2014). While therapeutic agents and analgesic techniques are available, a large number of patients report moderate to severe pain following surgery. For this reason, it is essential to continue researching analgesic treatments for post-operative pain.
Post-operative Pain Models

Brennan paw incision model in rodents
The Brennan rodent model of paw incisional pain has been extensively used for evaluating post-operative pain in humans. The procedure involves a 1 cm incision through the skin, fascia, and muscle in the hind paw.
Assessments:
- Von Frey
- Heat Stimuli
- Dynamic Weight Bearing

POP model in Pigs
Rodent models provide valuable information in early efficacy studies, however, the pig model provides a valuable translational tool for pain therapeutics due to their many similarities to human.
MD Biosciences offers the following pig models for evaluating POP:
- flank incision model
- leg incision model

Example Data
In a study, we aimed to evaluate the effect of Marcain and Exparel in the pig POP model. In additional to traditional pain assessments, we evaluate the locomotor activity of the animals. Data show open field post application in the pig POP model.
