The mean albumin concentration and COP were highest in CPP, suggesting that CPP may be a potential alternative to FFP for oncotic support and albumin replacement. CRYO contained higher activities of vWf and factor VIII than other products and could be used to treat vWf deficiency and hemophilia A. As vitamin K dependent coagulation factors II, VII, and X in CPP were similar to FFP, CPP may be an option for replacement of most of vitamin K dependent factors.

CASE DESCRIPTION A 2-year-old sexually intact female mixed-breed dog was evaluated at an emergency hospital approximately 5 hours after ingestion of an unknown amount of over-the-counter topical hair growth promoter containing 5% minoxidil foam. Vomiting and signs of lethargy were reported by the owner, and physical examination revealed tachycardia and hypotension. No treatments were performed, and the dog was transferred to a veterinary referral hospital for management of suspected minoxidil toxicosis. CLINICAL FINDINGS On arrival at the referral hospital, the dog was tachycardic (heart rate, 200 to 220 beats/min) and hypotensive (systolic arterial blood pressure, 70 mm Hg). Electrocardiography revealed a regular, narrow-complex tachycardia with no evidence of ventricular ectopy. TREATMENT AND OUTCOME Hypotension was effectively managed with a constant rate infusion of dopamine hydrochloride (12.5 μg/kg/min [5.7 μg/lb/min], IV). Once normotensive, the dog remained tachycardic and a constant rate infusion of esmolol hydrochloride (40 μg/kg/min [18.2 μg/lb/min], IV) was initiated for heart rate control. A lipid emulsion was administered IV as a potential antidote for the toxic effects of the lipophilic minoxidil, with an initial bolus of 1.5 mL/kg (0.7 mL/lb) given over 15 minutes followed by a continuous rate infusion at 0.25 mL/kg/min (0.11 mL/lb/min) for 60 minutes. While hospitalized, the dog also received maropitant citrate and ondansetron. Resolution of clinical signs was achieved with treatment, and the dog was discharged from the hospital 36 hours after admission. Four days later, the owner reported that the dog had made a full recovery and had returned to its typical behavior and activity level at home. CLINICAL RELEVANCE To the authors' knowledge, this is the first report of successful clinical management of accidental minoxidil toxicosis in a dog.

Objective: To investigate the impact of cryopoor plasma (CPP) continuous rate infusion (CRI) on albumin concentration and colloid osmotic pressure (COP) in critically ill dogs with hypoalbuminemia.Design: Retrospective study between 2013 and 2015 with a 90-day follow-up on survivors. Setting: University teaching hospital.Animals: Ten hypoalbuminemic dogs receiving a CPP CRI for albumin replacement or oncotic support. All patients with documented hypoalbuminemia or low COP receiving CPP administration for albumin or oncotic support during the study period were included. Interventions: CRI of CPP.Measurements and Main Results: Mean age was 7.4 ± 4.5 years. Mean survival prediction index score was 0.66 ± 0.13. Seven dogs were septic, with 2 of 7 in septic shock and 5 of 7 having septic peritonitis. The mean pre-and postinfusion albumin was 15 ± 4 g/L and 21 ± 2 g/L, respectively.The median pre-and postinfusion COP was 8.6 mm Hg (4.9-9.7 mm Hg) and 10.2 mm Hg (8.1-13.3 mm Hg), respectively. The median duration of CRI was 16 hours (11-121 h). The mean CPP rate was 1.8 ± 0.6 mL/kg/h, the mean crystalloid rate administered concurrently was 0.8 ± 0.9 mL/kg/h, and the mean hydroxyethyl starch rate administered concurrently was 1.2 ± 0.9 mL/kg/h. The difference in pre-and postinfusion albumin was significantly correlated with CPP rate (P = 0.0004), whereas the difference in pre-and postinfusion COP was correlated with hydroxyethyl starch rate (P = 0.0128). Mean duration of hospitalization was 8.6 ± 3.9 days. Mann-Whitney U and Fisher's exact tests were used to compare survivors and nonsurvivors. Survivors were significantly younger than nonsurvivors (3.5 vs 11.5 y, P = 0.033). No side effects were reported. Survival to discharge was 40% with identical 90-day survival. Of the nonsurvivors, 50% died naturally. Conclusions:There was an association between the rate of CPP and the change in albumin after CPP CRI in critically ill dogs, suggesting that CPP may be a viable option for treatment of hypoalbuminemia.

ObjectiveTo describe the use of manual therapeutic plasma exchange (TPE) to manage hepatic encephalopathy (HE) in a dog.Case summaryA 9‐year‐old neutered female Dachshund presented for HE secondary to a previously diagnosed portosystemic shunt. The hyperammonemia and severe clinical signs of HE persisted despite extensive medical management. Therapeutic plasma exchange was performed for stabilization prior to surgical shunt ligation. A total of 1 plasma volume was processed during a single manual TPE session. The ammonia immediately prior to TPE was 235 μmol/L (reference interval, 10‐30 μmol/L) and decreased to 117 μmol/L by the end of the session. The dog showed significant improvement in clinical signs shortly after the session and remained stable thereafter. Shunt ligation was performed 5 days later with no complications observed with TPE or postoperatively. The dog was discharged 3 days after surgery with no neurological signs and was doing well 100 days after surgery.New or unique information providedTo the authors’ knowledge, this is the first published report of manual TPE to manage HE in veterinary medicine. Therapeutic plasma exchange should be further investigated as a possible strategy to manage clinical signs of HE in patients that are refractory to medical management. Achieving this with manual TPE may be considered in patients that are too small for conventional TPE due to extracorporeal volume or in situations where conventional TPE is not available.
