- Pain treatment of lactating bitches is a clinically relevant, but complicated issue. Published scientific studies regarding the excretion of drugs in canine milk are scarce. When considering the risk of side effects in their offspring, lactating bitches have traditionally received very restricted analgesic and anti-inflammatory therapy. Our aim was to quantify the concentrations of carprofen in milk from lactating bitches and relate those to potential risks for the puppies. A second aim was to evaluate the impact mastitis may have on the concentration of carprofen in milk. A population of 100 bitches was enrolled in the study, among which 88 were bitches treated with carprofen after cesarean section (Group CS), eight were bitches with painful inflammatory conditions (Group I) and four were bitches with mastitis (Group M). The patients enrolled in the study received carprofen 4 mg/kg sc at day 1 followed by 2 mg/kg po every 12 h for the following 2-5 days. Owners were instructed to collect milk once a day for five days. The concentration of carprofen in the milk was quantified with ultra-performance liquid chromatography-tandem mass spectrometry. The data obtained were statistically analyzed as repeated-measures data with a mixed-model approach. Data were used to calculate the theoretical maximum total daily intake of carprofen by the puppies in order to perform a computerized simulation of the plasma concentration of carprofen in the puppies. Follow-up telephone interviews to check the status of the enrolled bitches and their litters occurred at one week and three-six months after treatment with car-profen. The major finding of the study was that the concentration of carprofen in the milk was <700 ng/ mL from bitches undergoing CS or suffering painful conditions other than mastitis. In comparison, administration of 2 mg/kg of carprofen sc or po to adult dogs, results in mean maximal plasma con-centrations of 19480 +/- 5420 ng/mL (mean +/- SD). Moreover, data suggests that inflammation of the mammary gland results in a higher concentration of carprofen in milk (up to 1300 ng/mL). In the computerized simulation, the plasma concentrations of carprofen in puppies in group CS and in group I are one tenth of the concentration in adult dogs receiving carprofen at standard doses. Considering the low excretion into milk, carprofen provides an analgesic alternative to lactating bitches without mastitis.(c) 2022 Published by Elsevier Inc.

- Background: Sepsis is a serious and potentially life-threatening condition and early diagnosis and appropriate treatment is crucial for survival. Pyometra is one of the most common diseases in intact female dogs. The disease often leads to sepsis (systemic inflammatory response syndrome, SIRS, caused by infection). Diagnostic markers for detecting sepsis are gaining increasing interest in veterinary medicine. Acute phase proteins (APPs) such as C-reactive protein (CRP) are useful for detecting systemic inflammation in dogs. Serum amyloid A (SAA) is another major APP in dogs that is not yet as widely used. Albumin is regarded as a negative APP and has earlier been evaluated for prediction of prognosis in septic dogs. The aim of the present study was to determine SAA, CRP and albumin concentrations in dogs with sepsis and pyometra and to evaluate whether these inflammatory markers are associated with length of postoperative hospitalization.Results: Thirty-one surgically treated bitches with pyometra were included, whereof 23 septic (SIRS-positive) and eight non-septic (SIRS-negative). Albumin concentrations were analyzed by routine automated methods. SAA and CRP analyses were performed with previously validated commercially available assays (ELISA and immunoturbidimetric). Mean (+/- SE) serum concentrations of SAA were significantly higher in septic (130.8 +/- 8.0 mg/L) compared to non-septic bitches (88.5 +/- 12.5 mg/L). Using a cut-off value for SAA of 109.07 mg/L (n = 31 bitches), the sensitivity and specificity for detecting sepsis was 74% and 50%, respectively. Serum albumin concentrations were not significantly different in septic compared to non-septic bitches (mean +/- SE, 25 +/- 1 g/L and 26 +/- 1 g/L, respectively). CRP concentrations were also not significantly different in septic (mean +/- SE 225.6 +/- 16.0 mg/L) compared to non-septic bitches (mean +/- SE, 176.0 +/- 27.1 mg/L). None of these inflammatory markers were associated with the outcome as measured by length of hospitalization.Conclusions: SAA concentrations were increased in dogs with sepsis induced by pyometra and may be useful as an adjunctive diagnostic marker for sepsis. To evaluate the full potential of SAA as a marker for sepsis also in other diseases, further studies are warranted.

- ObjectiveTo compare physiological effects of sufentanil-midazolam with sevoflurane for surgical anaesthesia in medetomidine premedicated rabbits.Study designProspective, randomized controlled experimental study.AnimalsEighteen female Himalayan rabbits, weight 2.10.1kg.MethodsPremedication with 0.1mg kg(-1) medetomidine and 5mg kg(-1) carprofen subcutaneously, was followed by intravenous anaesthetic induction with sufentanil (2.3g mL(-1)) and midazolam (0.45mg mL(-1)). After endotracheal intubation, anaesthesia was maintained with sufentanil-midazolam (n=9) or sevoflurane (n=9). Ovariohysterectomy was performed. Intermittent positive pressure ventilation was performed as required. Physiological variables were studied perioperatively. Group means of physiologic data were generated for different anaesthetic periods. Data were compared for changes from sedation, and between groups by anova. Post-operatively, 0.05mg kg(-1) buprenorphine was administered once and 5mg kg(-1) carprofen once daily for 2-3days. Rabbits were examined and weighed daily until one week after surgery.ResultsSmooth induction of anaesthesia was achieved within 5minutes. Sufentanil and midazolam doses were 0.5g kg(-1) and 0.1mg kg(-1), during induction and 3.9g kg(-1)hour(-1) and 0.8mg kg(-1)hour(-1) during surgery, respectively. End-tidal sevoflurane concentration was 2.1% during surgery. Assisted ventilation was required in nine rabbits receiving sufentanil-midazolam and four receiving sevoflurane. There were no differences between groups in physiologic data other than arterial carbon dioxide.In rabbits receiving sevoflurane, mean arterial pressure decreased pre-surgical intervention, heart rate increased 25% during and after surgery and body weight decreased 4% post-operatively. Post-operative problems sometimes resulted from catheterization of the ear artery.ConclusionSevoflurane and sufentanil-midazolam provided surgical anaesthesia of similar quality. Arterial blood pressure was sustained during sufentanil-midazolam anaesthesia and rabbits receiving sevoflurane lost body weight following ovariohysterectomy. Mechanical ventilation was required with both anaesthetic regimens.Clinical relevanceAnaesthesia with sufentanil-midazolam in medetomidine premedicated healthy rabbits is useful in the clinical and the research setting, as an alternative to sevoflurane.

- Background: Pyometra, a life-threatening bacterial infection of the uterus, is classified as open or closed depending on the functional patency of the cervix i.e. presence or absence of vaginal discharge. In closed cervix pyometra, pus and bacterial products accumulate in the uterus, which is thought to induce a more severe illness. The aim of this study was to investigate whether disease severity or outcome differed in dogs with open or closed cervix pyometra.Results: Prospectively collected data from 111 female dogs diagnosed with pyometra at the University Animal Hospital, Swedish University of Agricultural Sciences, Uppsala, intermittently during 2005-2012 was analyzed. Seventy-two dogs (65%) had open cervix, whereas 39 dogs (35%) had closed cervix. Differences between the two groups were explored by Wilcoxon Two Sample Test for continuous variables and Chi-square or Fisher's exact test for categorical variables. P < 0.05 was considered significant.In dogs with open cervix the median age was 9.0 years and the median weight 26.0 kg. In dogs with closed cervix the median age was 9.6 years and the median weight 25.0 kg, with no significant differences between the groups (p = 0.69 and 0.24, respectively). Five dogs (4.5%) died, all with open cervix, and 16 dogs (14%) had complications. The general physical condition was moderately or severely depressed in 30% (21/71) of dogs with open cervix (severely depressed in 4 dogs, moderately depressed in 17 dogs) and in 56% (22/39) of dogs with closed cervix (severely depressed in 3 dogs, moderately depressed in 19 dogs). The general physical condition was mildly depressed in 41 dogs with open cervix and 16 dogs with closed cervix, whereas it was normal in nine dogs with open cervix and one dog with closed cervix. None of the included dogs had very severely depressed general physical condition or were non-responsive.Leukocytosis, neutrophilia, monocytosis and moderately to severely depressed general condition was more commonly found in dogs with closed cervix (p = 0.003, p = 0.008, p = 0.003 and p = 0.006, respectively). Sepsis was more commonly present in closed cervix pyometra (77%, 30/39 dogs) compared to open cervix pyometra (51%, 36/71 dogs) (p = 0.007). Presence of prolonged postoperative hospitalization did not differ significantly between the two groups.Conclusions: In dogs with closed cervix, sepsis was more common, the general physical condition more often moderately to severely depressed and leukocytosis, neutrophilia and monocytosis more frequently found. The results showed that closed cervix was associated with a more severe illness than open cervix at admission but not with poorer outcome as measured by postoperative hospitalization. These findings may be clinically valuable for optimizing monitoring and treatments in dogs with the disease.

- Conclusions: Several clinically useful indicators were identified. Leucopenia was the most important marker, associated with 18-fold increased risk for peritonitis and an over three-point-five increased risk for prolonged hospitalization. Fever/hypothermia, depression and pale mucous membranes were associated with increased risk for peritonitis and/or prolonged hospitalization. The results of the present study may be valuable for identifying peritonitis and predicting increased morbidity in surgically treated bitches with pyometra.
