Effects of compressive abdominal bandaging and transrectal palpation on intra-abdominal pressures in horses.
Abstract: To determine the effect of an abdominal support wrap and transrectal abdominal palpation on intra-abdominal pressures (IAPs) measured directly from the peritoneal space. Methods: Prospective, experimental study. Methods: A university-based equine research facility. Methods: Ten healthy adult horses, 5 males and 5 females. Methods: IAPs were measured through an intraperitoneal cannula zeroed at a height midway between the height of the tuber ishii and point of the shoulder. Triplicate measurements were obtained at rest, during transrectal palpation, after placement of an abdominal support wrap, and during transrectal palpation with the support wrap still in place. Simultaneous mean arterial pressures were obtained using a tail cuff and abdominal perfusion pressures were calculated using the measured IAP minus the measured mean arterial pressures. Results: Baseline direct pressure measurements were subatmospheric (-4.5 ± 3.0 cm H(2) O). IAPs were not significantly affected by transrectal palpation, but were significantly increased after placement of an abdominal support wrap (-1.19 ± 3.01 cm H(2) O; P = 0.01). Abdominal perfusion pressures were not significantly affected by either transrectal palpation or application of the support wrap. Conclusions: IAPs were significantly increased after application of an abdominal support wrap commonly used after exploratory laparotomy. Further investigations are warranted to determine the clinical implications of abdominal bandaging on IAP and its implications on postoperative complications including intra-abdominal hypertension. However, transrectal abdominal palpation likely does not contribute to abdominal hypertension in normal horses.

This research article explores how using an abdominal support wrap and transrectal abdominal palpation affect the intra-abdominal pressures in horses. It suggests that abdominal bandaging significantly increases these pressures, whereas palpation doesn’t seem to contribute to intra-abdominal hypertension.
Research Context
- The study was conducted in a university-based equine research facility, using a sample of ten healthy adult horses, comprised of 5 males and 5 females.
- The research aimed to determine the impacts on intra-abdominal pressures (IAPs), which were measured directly from the peritoneal space, resulting from the use of an abdominal support wrap and transrectal abdominal palpation.
Research Methods
- IAPs were measured through an intraperitoneal cannula zeroed at a height midway between the height of the tuber ishii and point of the shoulder.
- Three separate measurements were collected while the horses were at rest, during the transrectal palpation, after the placement of the abdominal support wrap, and during the palpation with the wrap still applied.
- Mean arterial pressures were simultaneously collected via a tail cuff, and abdominal perfusion pressures were calculated by subtracting the measured mean arterial pressures from the measured IAP.
Research Findings
- The baseline direct pressure measurements were found to be subatmospheric (-4.5 ± 3.0 cm H(2) O).
- The IAPs did not appear to be significantly affected by transrectal palpation. However, IAPs significantly increased after the placement of an abdominal support wrap (-1.19 ± 3.01 cm H(2) O; P = 0.01).
- Neither the application of the support wrap nor the transrectal palpation noticeably affected the abdominal perfusion pressures.
Conclusion and Recommendations
- The use of an abdominal support wrap, often applied post-exploratory laparotomy, was found to significantly increase IAPs, a discovery which warrants further investigation to determine potential clinical consequences and implications for postoperative complications, including intra-abdominal hypertension.
- Unlike the use of the abdominal wrap, transrectal abdominal palpation did not seem to contribute to abdominal hypertension in normal horses.
