Evaluation of the relationship between peripheral pulse palpation and Doppler systolic blood pressure in dogs presenting to an emergency service
Ateca et al JVECC 2018
Mean SBP not diff b/w femoral pulse but diff in dorsal metatarsal pulse group
Absent metatarsal pulse 7.6x times more likely to be hypotensive (SBP<90mmHg)
Retrospective evaluation of the prognostic utility of plasma lactate concentration, base deficit, pH, and anion gap in canine and feline emergency patients
Kohen JVECC 2018
Plasma lactate, BD and pH predicted mortality in dogs
Plasma lactate is an independent predictor of mortality inc cats
Mortality was highest for animals with lactic acidosis
Evaluation of pulse pressure variation and pleth variability index to predict fluid responsiveness in mechanically ventilated isoflurane-anesthetized dogs
Sano jvecc 2018
PPV and PVI increased consistently with decreased blood volume and decreased with volume expansion
More were more accurate than CVP
In mechanically ventilated dog:
Pulse pressure variation (PPV) at 11 was 79% Sn 80% Sp
Pleth variability index (PVI) of 9.3% was 86% Sn and 70% Sp
for predicting fluid responsiveness
Evaluation of end-tidal carbon dioxide as a predictor of return of spontaneous circulation in dogs and cats undergoing cardiopulmonary resuscitation
hogen jvecc 2018
ROSC patients had higher initial, peak, average, and delta PetCO2
Optimal cutoff PetCO2 is 18 mmHg at minute 2 of CPR was the strongest discriminator
34% achieved ROSC, more common for in-hospital CPA
(Hofmeister 2009: previous study: ETCO2 >15 mmHg in dogs and >20 mmHg in cats)
Tissue oxygen saturation in dogs with acute hemorrhage
gray jvecc 2018
Healthy dogs had higher tissue hemoglobin O2 saturation (StO2)
Measures Hb sat in microvasculature (rather than SpO2 = arterial blood)
StO2 cutoff of 87.6% can be used to identify patient being in shock
Spontaneous hemoperitoneum and anaphylactic shock associated with Hymenoptera envenomation in a dog
Dana J. Caldwell et al jvecc 2018
Anaphylaxis secondary to Hymenoptera envenomation –> spontaneous hemoperitoneum
No GB edema and ALT was only mildly elevated (198)
Evaluation of biomarkers of kidney injury following 4% succinylated gelatin and 6% hydroxyethyl starch 130/0.4 administration in a canine hemorrhagic shock model.
Boyd et al jvecc 2019
GELO was associated with greater magnitude increases in urine biomarkers of AKI (uNGAL, uCLUST, uCYSC, uKIM) and more frequent marked tubular microvesiculation
increased despite adequate glomerular filtration rate and tubular function
Evaluation of tissue oxygen saturation in naturally occurring canine shock patients.
Berg jvecc 2019
StO2 = indicative of venous hemoglobin oxygen saturation, surrogate for DO2
Dogs w/ naturally occurring shock had lower StO2 (65%)
Mod linear correlation to APPLE score
Development and validation of a hemangiosarcoma likelihood prediction model in dogs presenting with spontaneous hemoabdomen: The HeLP score.
Schick, et al jvecc 2019
nontraumatic hemoabdomen
Score based on BW, TP, plt count and TXR findings
low, medium, or high risk
AUROC 0.77
Investigation of percentage changes in pulse wave transit time induced by mini-fluid challenges to predict fluid responsiveness in ventilated dogs.
Sano jvecc 2019
PWTT was calculated as the time from the ECG R-wave peak to the rise point of the pulse oximeter plethysmography wave
- inversely proportional to SV and has a strong negative correlation with SV
- good trending ability to detect changes in SV measured by thermodilution technique
- 3 mL/kg = minimum amount
- Pulse wave transit time (PWTT%Δ) 2.5% accurately predicted fluid responsiveness.
A pilot study comparing bone marrow aspirates and venous blood for emergency point-of-care blood parameters in healthy dogs.
Ackert et al jvecc 2019
IO and IV difference: Na, Cl, BUN, K, HCT
K and HCT sig. different. K higher in IO
Retrospective evaluation of pericardial catheter placement in the management of pericardial effusion in dogs (2007-2015):18 cases.
Cook et al jvecc 2019
Done via modified seldinger technique
Main SE was arrhythmia and required tx more often (22 vs 13%)
Utility of admission lactate concentration, lactate variables, and shock index in outcome assessment in dogs diagnosed with shock.
Zollo et al jvecc 2019
Shorter duration of lac >2, greater lactate clearance, and smaller area under the lactate conc vs time curve
were found in survivor
admission SI and time to normalize SI was no diff.
Evaluation of the agreement between a point-of-care lactate meter and a handheld laboratory analyzer in cats treated in emergency practice
Mark J. Acierno et al jvecc 2020
New POC lactate meter is in agreement w/ handheld analyzer in CI cats
Lactate Plus machine (new machine) compared to iSTAT
Perception of small animal cardiopulmonary resuscitation of owners presenting to a small animal teaching clinic including a large first opinion service
Jennifer A. Oberholtzer et al jvecc 2020
The general public are interested in CPR
