The effects of repeated intravenous iohexol administration on renal function in healthy beagles – a preliminary report

Abstract: BackgroundContrast induced nephrotoxicity (CIN) is a well described syndrome in humans undergoing contrast medium examinations. To date CIN has received minimal attention in the veterinary literature despite increasing use of contrast medium examinations in computed tomographic studies.MethodsThis prospective study evaluated the effect of 1290 mg/kg iohexol given intravenously to 5 normal beagle dogs in a divided dose at an interval of 6–8 weeks. Renal function was evaluated by means of scintigraphically deter… Show more

“…A lateral tomogram was performed before all CT scans and the field of view adjusted to include the diaphragm and ischial tuberosities. IV contrast was not administered because repeated administration with positional change could have potentially resulted in iatrogenic contrast induced nephrotoxicity …”

“…Trendelenburg position has been recommended for ovariohysterectomy typically by elevating the pelvis 30° above the abdomen, so that the viscera moves away from the uterine body to improve surgical exposure of the reproductive tract . Computed tomography (CT) provides excellent abdominal detail because of spatial resolution and lack of superimposition . Surface detail of viscera should be enhanced by the presence of a negative contrast medium such as CO 2 in the peritoneal space.…”

“…Os valores mé-dios da creatinina sérica dos grupos que receberam diferentes MCI neste experimento permaneceram constantes ao longo do tempo, sem diferenças significantes com os valores basais, não se constatando declínio expressivo da TFG avaliada indiretamente. Estudos em cães que utilizaram iohexol pela via intravenosa, em doses semelhantes ou maiores que a desta pesquisa, também não detectaram aumento significantes da concentração sérica de creatinina, em diferentes situações: após 60, 80 minutos, 48 e 72 horas, em cães saudáveis ou com disfunção renal (Choi et al 2001) e após 72 horas, em animais saudáveis (Kirberger et al 2012) ou ASA (American Society of Anesthesiologists) 1 e 2 (Carotenuto et al 2013).…”

“…Em rins de cães adultos saudáveis, o potencial nocivo dessas substâncias foi constatado após duas doses, via intravenosa, de contraste iodado em exames de TC, pela diminuição de 17% na TFG, avaliado pela cintilografia (Kirberger et al 2012). No homem, desidratação, senilidade, insuficiência cardíaca congestiva (ICC) e disfunção renal preexistente são consideradas fatores de risco de maior relevância, que potencializam os efeitos renais dos MCI, predispondo à reação adversa renal tardia, também denominada nefropatia induzida por contraste (NIC) (Morcos 1998, Murphy et al 2000, Thomsen 2003, Toprak 2007, Wong & Irwin 2007, Bartorelli & Marenzi 2008, McCullough 2008, Pucelikova et al 2008, Santos et al 2011, Rudnick et al 2014.…”
