Comparison between pulse pressure variation and systolic pressure variation measured from a peripheral artery for accurately predicting fluid responsiveness in mechanically ventilated dogs.

Objective: To compare pulse pressure variation (PPV) and systolic pressure variation (SPV) measured from a peripheral artery to predict fluid responsiveness in anesthetized healthy dogs.

Study Design: Prospective study.

Animals: A total of 39 dogs (13.

Use of aortic flow indexes derived from transthoracic echocardiography to evaluate response to a fluid challenge in anesthetized dogs.

Objective: To evaluate the ability of transthoracic echocardiographic aortic flow measurements to discriminate response to a fluid challenge (FC) in healthy anesthetized dogs.

Study Design: Prospective experimental study.

Animals: A total of 48 isoflurane-anesthetized dogs (14.

Comparison of the diagnostic accuracy of dynamic and static preload indexes to predict fluid responsiveness in mechanically ventilated, isoflurane anesthetized dogs.

Objective: To compare the diagnostic accuracy of pulse pressure variation (PPV), stroke volume variation from pulse contour analysis (SVV), plethysmographic variability index (PVI), central venous pressure (CVP) and global end-diastolic volume index measured by transpulmonary thermodilution (GEDVI) to predict fluid responsiveness (FR) in dogs.

Study Design: Prospective study.

Animals: A group of 40 bitches (13.

Effects of 6% tetrastarch or lactated Ringer's solution on blood coagulation in hemorrhaged dogs.

Background: Tetrastarch solution (TS) can impair coagulation but the clinical relevance of this impairment is unclear in veterinary medicine.

Objective: Compare the effects of volume replacement (VR) with lactated Ringer's solution (LRS) or 6% TS on coagulation in hemorrhaged dogs.

Animals: Six healthy English Pointer dogs (19.

Effects of pneumoperitoneum and of an alveolar recruitment maneuver followed by positive end-expiratory pressure on cardiopulmonary function in sheep anesthetized with isoflurane-fentanyl.

Objective: To investigate the effects of pneumoperitoneum alone or combined with an alveolar recruitment maneuver (ARM) followed by positive end-expiratory pressure (PEEP) on cardiopulmonary function in sheep.

Study Design: Prospective, randomized, crossover study.

Animals: A total of nine adult sheep (36-52 kg).

Comparison of two species-specific oscillometric blood pressure monitors with direct blood pressure measurement in anesthetized cats.

Objective: To compare the performance of 2 species-specific oscillometric blood pressure (OBP) monitors (petMAP and petMAP ) with direct blood pressure measurement in anesthetized cats.

Design: Prospective, experimental study.

Setting: Veterinary teaching hospital.

Effects of different inspired oxygen fractions on sildenafil-induced pulmonary anti-hypertensive effects in a sheep model of acute pulmonary embolism.

Aims: Sildenafil is a pulmonary anti-hypertensive agent whose action could be modified by different fractions of inspired oxygen (FiO2). We compared the effects of pure oxygen (FiO2 > 90%) or room air (21% FiO2) on the cardiopulmonary actions of sildenafil in sheep with acute pulmonary embolism (APE).

Main Methods: Thirty-two anesthetized, mechanically ventilated sheep (34.
