“…Sedation with a combination of atropine, acepromazine, and ketamine did not alter the intrarenal RI in cats (Rivers et al, 1996). Yet, anesthesia with isofluorane did increase both the intrarenal RI and PI in cats (Mitchell et al, 1998). In one study coping with the effects of short-term anesthetics on renal hemodynamics it was shown that while propofol had a minimal effect, a xylazine-ketamine combination and thiopental caused a significant drop in intrarenal RI .…”

“…81 Isoflurane does cause a predictable decrease in GFR during anesthesia which is thought to be due to a direct effect on the renal autoregulatory system. 49 Bolliger et al 18 used general anesthesia to restrain their subjects for blood collection and scintigraphy as well as during surgery. During their pre-operative scintigraphic measurements and blood collection the cats were anesthetized with isoflurane only, while for all subsequent studies acepromazine and butorphanol were administered as a premedicant.…”

Objective:To assess effects of bisection nephrotomy on renal function, size, and morphology in cats over a period of 12 weeks. Study Design:Controlled, randomized, blinded experiment. Sample Population:Ten adult female cats. Methods:Glomerular filtration rate (GFR), as determined by quantitative renal scintigraphy using Results:No significant differences in mean GFR and kidney size of the operated versus unoperated kidneys were observed at any time period. Individual GFR and renal size of all except one of the cats remained within normal limits. Two additional cats had evidence of transient ureteral obstruction in the immediate post-operative period. No significant histologic abnormalities were observed in any biopsy. Conclusions:Bisection nephrotomy in normal cats did not adversely affect renal function or morphology over the three month post-operative period. Clinical Relevance:Bisection nephrotomy can be safely performed in normal feline kidneys without causing a significant deleterious effect on renal function. Studies in animals with pre-existing renal insufficiency are needed to insure no adverse effects would occur in clinical cases where this surgical procedure is warranted.

“…In cats, sedation with a combination of atropine, acepromazine, and ketamine did not alter the renal RI 14 . However, anaesthesia with isofluorane increased both the renal RI and PI in cats 15 . In the literature, there are no sufficient data from comparison of short-acting anaesthetic agents' effects on DU parameters.…”

SummaryThis study was carried out to determine the effects of short-acting anaesthetics on haemodynamic function determined by Doppler ultrasonography. Prior to anaesthesia, Doppler parameters [peak systolic blood flow velocity (psBFV), end-diastolic blood flow velocity (edBFV), minimum diastolic blood flow velocity (mdBFV) and resistive index (RI)] were obtained from the right common carotid artery (CCA), abdominal aorta (AA) and right kidney in New Zealand rabbits (n=24). Animals were then divided into 3 groups to be anaesthetized with propofol (Group P), 2.5% thiopental sodium (Group T) and xylazine/ketamine HCl (Group XK). During anaesthesia the same Doppler measurements were made. Compared with baseline values, psBFV obtained from CCA increased in Group P (P<0.02) and insignificantly changed in Groups T and XK. psBFV measured from AA in Groups T and XK decreased as compared with baseline values. In the right kidney, psBFV in Group P and edBFV in Group T increased, whereas RI value in Groups T and XK decreased. In conclusion, comparing baseline values, propofol anaesthesia did not significantly alter RI measured from CCA and kidney and blood flow velocities measured from AA. The data suggest that propofol anaesthesia in rabbits results in minimal changes in Doppler parameters.

Anestezi öncesi Yeni Zelanda tavşanlarının (n=24) sağ arteria carotis communis (CCA), aorta abdominalis (AA) ve sağ böbreğinden Doppler parametreleri [en yüksek sistolik kan akım hızı (psBFV), diyastol sonu kan akım hızı (edBFV), en düşük diyastolik kan akım hızı (mdBFV) ve rezistif indeks (RI)] elde edildi. Hayvanlar propofol (Grup P), %2.5 tiyopental sodyum (Grup T) ve ksilazin/ ketamin HCl (Grup XK) ile anestezi altına alınarak, üç grup oluşturuldu. Anestezi sırasında aynı ölçümler tekrarlandı. Bazal değerler ile karşılaştırıldığında CCA'dan elde edilen psBFV Grup P'de yükseldi ve Grup T ve XK'daki değişim önemsizdi. Grup T ve XK'da AA'dan ölçülen psBFV bazal değerler ile kıyaslandığında azaldı. Sağ böbrekte, Grup P'nin psBFV ve Grup T'nin edBFV değerleri artarken, Grup T ve XK'da RI değeri azaldı. Sonuç olarak, propofol anestezisi bazal parametreler ile karşılaştırıldığında, CCA'deki RI, intrarenal RI ve AA'daki kan akımı hızlarını önemli ölçüde değiştirmediği tespit edildi. Veriler propofol anestezisinin tavşanlarda Doppler parametrelerini minimal düzeyde etkilediğini göstermektedir.
