Abstract

OBJECTIVE

Compare changes in intra-abdominal pressure (IAP), abdominal perfusion pressure (APP), hemodynamics, and clinicopathological variables in nonpregnant and late-term pregnant queens undergoing elective ovariohysterectomy (OHE) and evaluate the effect of patient positioning on IAP and APP measurements.

ANIMALS

18 late-term pregnant queens and 25 nonpregnant controls.

PROCEDURES

Temperature, heart rate (HR), Doppler blood pressure (DBP), IAP (dorsal and right lateral), PCV, total protein (TP), and lactate were recorded preoperatively, at abdominal wall closure (dorsal IAP only), and postoperatively under general anesthesia. Uterine weight, blood loss, and surgical duration were recorded. Abdominal perfusion pressure was calculated as DBP minus IAP.

RESULTS

Pre- and postoperatively, pregnant queens had lower DBP, APP, and PCV compared to controls (P < 0.001). IAP was higher in pregnant queens preoperatively (P < 0.001). Controls had a decrease in HR and increase in IAP, while both groups had a decrease in body temperature, DBP, APP, and lactate over time (P < 0.05). Pregnant queens had a decrease (P = 0.029), and controls had an increase in TP (P = 0.001). Blood loss and surgical time were greater for pregnant queens (P < 0.001). Dorsal IAP and APP were higher and lower than right lateral measurements (P < 0.001), respectively, and correlation was strong.

CLINICAL RELEVANCE

Hemodynamics and APP are impaired in late-term pregnant queens undergoing OHE, and increased monitoring is warranted. Although strongly correlated, feline IAP and APP measurements in dorsal and right lateral recumbency are not interchangeable.

Abstract

OBJECTIVE

To investigate the incidence and patterns of gunshot wound trauma in patients that were presented to an urban level 1 veterinary trauma center before and after the start of the coronavirus disease of 2019 (COVID-19) pandemic.

ANIMALS

24 dogs and 1 cat.

METHODS

Medical records were retrospectively reviewed for patients presenting with gunshot wound injuries between March 2018 and February 2020 (prepandemic) and March 2020 and February 2022 (pandemic). The total number of patients presented to the hospital during those same time periods was also obtained. Patient data were collected including species, breed, age, sex, location of injury, trauma score (if available), surgical procedures performed, length of hospitalization, and case outcome.

RESULTS

In the prepandemic period, 9 patients were presented for gunshot wound injuries, whereas there were 16 patients evaluated for gunshot wound injuries during the pandemic period. The total number of gunshot wound cases increased by 77.8% in the pandemic period. The total number of hospital patient visits, however, decreased by 12.2% in the pandemic period as compared to the prepandemic period: 65,168 versus 74,262 patients, respectively. Injuries were predominantly localized to the extremities (55%) in the prepandemic period versus maxillofacial (56%) in the pandemic period.

CLINICAL RELEVANCE

There was an increased number of gunshot wound injuries in companion animals presenting to an urban level 1 veterinary trauma center during the COVID-19 pandemic. A shift in the predominant location of injury was also identified during the pandemic period. This study highlights the ramifications that societal dynamics can have on animal health and welfare.
