Use of ultrasound to diagnose diaphragmatic rupture in dogs and cats
No full textTwenty-one cats and six dogs that presented to a first-opinion clinic with signs of dyspnea and muffled
cardiac auscultation received ultrasonography to look for signs of diaphragmatic rupture. The presence
or absence of diaphragmatic rupture was subsequently determined on the basis of unequivocal radiographic
signs, surgical findings, or necropsy. Consistent findings in animals with diaphragmatic rupture
were irregular or asymmetric cranial aspect of the liver and abdominal viscera in the thorax. Accuracy
of ultrasonography was 25/27 (93%). One false-negative result occurred in a cat with a chronic diaphragmatic
rupture in which adhesions between the liver and lung simulated the appearance of an
intact diaphragm. One false-positive result occurred in a dog with an abscess involving the left lung and
pleural cavity, which was misinterpreted as the stomach. The results of this study support use of
ultrasonography in animals with suspected diaphragmatic rupture
The effect of administering a dopamine agonist (cabergoline) on follicular and luteal development during pro-estrus and estrus in the female greyhound.
No full textTo study the effect of the dopamine agonist Cabergoline, on ovarian activity in the female dog during pro-estrus and estrus, 6 greyhounds were treated with 5 μg/kg per os of Cabergoline for 20 days beginning on the first day of pro-estrus; 6 animals were left untreated (controls). Ovarian morphology was determined by ultrasound examination once a day during pro-estrus and twice a day during estrus. Follicles were divided into three classes on the basis of their diameter: F1 (6 mm). The presence and diameters of post-ovulatory follicles (F-POST) and corpora lutea (CL) were also recorded. Blood samples were taken once a day during pro-estrus and twice a day during estrus. The plasma was assayed for LH, prolactin and progesterone by radioimmunoassay. There were no differences between Cabergoline-treated and control dogs in the duration of pro-estrus or estrus. There was a progressive increase in follicle diameter from the start of pro-estrus when follicles were mainly class F1 to the day of estrus when follicles were mainly class F3. Three days after the start of estrus, the first F-POST follicles were detected. This pattern of development continued and on day 5 the first CLs were detected. By day 9, only CLs were detected. The peak of pre-ovulatory LH was within 3 days of estrus and ovulation was detected in all animals within 3 days of the LH peak. There were no differences in LH concentrations between groups. Plasma prolactin levels varied between animals and were reduced in treated dogs, however, this was not statistically significant (P = 0.12). Plasma progesterone levels were below 1.0 ng/ml before the LH surge and thereafter gradually increased. There were no differences in plasma progesterone concentrations between treated and control dogs. In conclusion these results show that the administration of the dopamine agonist Cabergoline during pro-estrus and estrus did not affect the duration of pro-estrus or estrus or the pattern of follicular and luteal development in female do
Effect of intraurethral administration of atracurium besylate in male cats with urinary obstruction due to naturally acquired urethral plugs.
No full textABSTRACT
Objective. The aim of this study was to evaluate the effect of intraurethral administration of atracurium besylate (AB) on urinary obstruction due to urethral plugs in male cats.
Methods. Forty-five male cats were divided into: (i) the treatment group (n=25) in which the urethral area was irrigated with AB (0.5 mg/ml) and (ii) the control group (n=20) not irrigated with AB.
Results. In the treatment group, the urethral plugs were removed at the first and second attempts in 64% and 36%, respectively, of the animals. The corresponding values in the control group were 15% and 85%. The proportion of cats in which the plug was removed at the first attempt was higher in the treatment group than in the control group (16/25 versus 3/20, respectively; P<0.05). The overall mean (±SD) time required for removal of the urethral plugs was 21.1±16.2 sec in the treatment group and 235.2±232.4 sec in the control group (P<0.001).
Clinical significance. The results of this study indicate that in adult male cats with urethral plugs, urethral administration of AB increases the proportion of animals in which the obstruction is removed at the first attempt and reduces the time required to remove the urethral plugs
Effect of urethral infusion of atracurium besylate on manual bladder expression in dogs and cats with spinal cord injuries: A randomised trial
No full textThe aim of this randomised trial was to assess the effect of urethral infusion of atracurium besylate in dogs and cats with signs of urinary retention secondary to lesions affecting spinal cord segments T3–L3. Eighteen dogs and six cats with urinary retention were examined and scored before treatment on the degree of difficulty of inducing bladder emptying by manual bladder compression. Animals were subsequently treated in a blinded fashion by the same operator with urethral infusion of 2–4 ml of either a solution of 0.5 mg/ml of atracurium (treatment group) or placebo (control group) and, after five minutes, a second attempt was made to induce bladder emptying by manual compression and a post-treatment score assigned. Pretreatment scores did not differ between the treatment and control groups (5.6±0.8 v 6.2±0.7, respectively; P=0.22); however, post-treatment scores were significantly lower in the treatment group compared with the control group (2.9±0.4 v 5.9±0.3; P<0.05). Urethral infusion of atracurium facilitates manual bladder expression in dogs and cats with urinary retention secondary to spinal cord injuries. No side effects were recognised
