ABSTRACT
Objective: This study aimed to describe the successful identification and treatment of severe hyperkalemia, cardiac arrhythmia, rhabdomyolysis, and acute kidney injury (AKI) in a domestic cat that underwent general anesthesia for abdominal exploratory surgery. The definitive underlying cause remains unknown; however, a reaction to propofol is suspected. Case summary: A 6-month-old intact male domestic short-hair cat underwent general anesthesia and developed severe intraoperative rhabdomyolysis, hyperkalemia, ventricular fibrillation, and AKI during surgery despite a documented mild hypokalemia and normal creatinine before inducing anesthesia. Propofol was administered as part of the anesthetic protocol. The patient was resuscitated successfully and responded well to advanced medical intervention. The hyperkalemia and AKI were resolved within less than 24 h from surgery and rhabdomyolysis was resolved at the time of recheck 5 days later. New or unique information provided: While previously suspected in dogs, to the authors' knowledge, propofol-related infusion syndrome (PRIS) has not been reported in domestic cats. Veterinary professionals should be aware that drug-induced intraoperative rhabdomyolysis and hyperkalemia can develop unexpectedly and should remain a differential for acute cardiac arrhythmias or cardiac arrest and AKI.
ABSTRACT
BACKGROUND: Placement of a subcutaneous ureteral bypass (SUB) device is an effective method to relieve all causes of ureteral obstruction in cats. Complications involving migration within the gastrointestinal tract have been seldomly described. OBJECTIVES: To characterize transmural migration of SUB devices within the digestive tract in cats. ANIMALS: Eleven migrated SUB catheters identified in 8 cats between 2017 and 2021. METHODS: Retrospective review of medical records of cats with a SUB device in which migration into the gastrointestinal tract was identified. RESULTS: The median time from SUB device placement to implant migration was 928 days (201-2298 days). Seven cats had obstruction of the SUB device and a positive urine culture at diagnosis. The migration was identified by ultrasound in 6/11, pre-operative contrast radiography in 2/2, and only at time of surgery in 3 SUB devices. All cats underwent surgical correction. Four nephrostomy and 7 cystotomy catheters migrated. Migration occurred into the duodenum (3/11), jejunum (7/11), and colon (1/11). SUB devices were removed in 7 cats and replaced in 2 cats, with 1 cat diagnosed with 2 migration events. Gastrointestinal resection and anastomosis were performed in 7/8 cats and an enterotomy in 2 cats. Six cats survived to discharge. The median follow-up time after migration diagnosis was 365 days (range, 0-1114 days) and 2 cats are still alive. CONCLUSIONS AND CLINICAL IMPORTANCE: Although a rare complication, migration of SUB device should be considered in cats with SUB device obstruction and a positive urine culture.

OBJECTIVE: To examine owner experiences with and perceptions of owner-witnessed resuscitation (OWR) in veterinary medicine and to determine if previous experience with family-witnessed resuscitation (FWR) influenced perceptions. DESIGN: Multicenter survey. SETTING: Two academic and 2 private practice referral hospitals in the United States. SUBJECTS: Four hundred and seven clients presenting their small animal or exotic pet to the emergency service, or owners of patients hospitalized in the small animal ICU, April 1 to May 15, 2019. INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: Anonymous, online survey. Demographic variables, familiarity with CPR, previous experience with FWR or OWR, and open-ended questions and 4-point Likert items assessing level of agreement with statements on OWR were included. Scores equal or greater than 2 represented positive agreement. An overall OWR mean score was calculated from Likert items. Seventy-nine (19.4%; 95% confidence interval [CI], 15.7%-23.7%) participants reported having been involved with FWR, and 13 (3.2%; 95% CI, 1.8%-5.5%) reported having witnessed CPR on their pet. Owners were significantly more likely to participate in OWR if they had been present for FWR (P = 0.0004). Ninety-two percent of respondents who had been present for OWR would elect to be present again (95% CI, 62.1%-99.6%). Whether present for OWR or not, owners believed there may be benefits from witnessing CPR and had overall positive feelings toward the practice (OWR mean score, 2.87, SD 0.45 and 2.68, SD 0.54, respectively). Most respondents (78.6%; 95% CI, 74.2%-82.4%) felt that owners should be offered the opportunity to witness CPR on their pets. CONCLUSIONS: Owners expressed overall positive experiences with and attitudes toward OWR and believe the option for presence should be provided. As pet owners become more aware of FWR in human medicine, veterinarians may need to be prepared to entertain the possibility of OWR and owners' wishes to remain with their pet during CPR.
