Cardiopulmonary effects of an intravenous infusion of fentanyl in cats during isoflurane anesthesia and with concurrent acepromazine or dexmedetomidine administration during anesthetic recovery
CONCLUSIONS AND CLINICAL RELEVANCE: Fentanyl transiently improved indices of cardiopulmonary performance when administered to healthy cats anesthetized with isoflurane. The cardiovascular effects of acepromazine and dexmedetomidine in healthy cats receiving fentanyl during recovery from isoflurane anesthesia differed, but measured cardiopulmonary parameters remained within acceptable limits.PMID:33764830 | DOI:10.2460/ajvr.82.4.261

Cardiovascular and respiratory effects of carbon dioxide pneumoperitoneum in the domestic rabbit (Oryctolagus cuniculus).
In conclusion, pneumoperitoneum with carbon dioxide causes an increase in ETCO2, PaCO2, and PIP, whereas cardiac output and CI decrease. These cardiorespiratory changes should be considered when determining the optimal IAP for laparoscopic procedures in rabbits. PMID: 32255905 [PubMed - in process]

Echocardiographic assessment of left ventricular systolic function in neonatal calves with naturally occurring sepsis or septic shock due to diarrhea
The objectives of this study were to evaluate the clinical value of echocardiography for monitoring left ventricular (LV) systolic function in septic calves. A prospective longitudinal study was performed using a convenience sample. Twenty septic calves and 10 healthy calves were enrolled in the study. Arterial blood pressure (BP) was measured and M-mode echocardiography performed to characterize LV systolic function; the latter included measurement of ejection fraction, EF; stroke volume, SVI and cardiac output indexed to body weight, CI; E-point of septal separation, EPSS; pre-ejection period, PEP; ejection time, LVET; r...

Change of heart dimensions and function during pregnancy in goats
Publication date: June 2018Source: Research in Veterinary Science, Volume 118Author(s): Olga Szaluś-Jordanow, Michał Czopowicz, Lucjan Witkowski, Agata Moroz, Marcin Mickiewicz, Tadeusz Frymus, Iwona Markowska-Daniel, Emilia Bagnicka, Jarosław KabaAbstractThe study aimed to evaluate the effect of pregnancy on heart diameters and function in goats. Transthoracic echocardiography of 12 female dairy goats of two Polish regional breeds was performed. A Mindray M7 diagnostic ultrasound system with Phased Array transducer was used. Simultaneously, electrocardiography was recorded. All animals were examined four times – at m...

Effect of different analgesic techniques on hemodynamic variables recorded with an esophageal Doppler monitor during ovariohysterectomy in dogs.
This study compared the efficacy of intravenous (IV) fentanyl and ketamine with lumbosacral epidural lidocaine in dogs undergoing ovariohysterectomy. Dogs with esophageal Doppler monitoring (n = 112) were included in this retrospective study. All dogs were premedicated with dexmedetomidine and methadone, induced with IV propofol or alfaxalone and maintained using isoflurane and IV fentanyl, IV ketamine, or epidural lidocaine. Heart rate (HR), mean arterial pressure (MAP), expired fraction of isoflurane (ETIso), stroke distance (SD), minute distance (MD), peak velocity (PV) and mean acceleration (MA) were recorded before an...
