“…Abnormalities of oesophageal function, such as megoesophagus, reflux oesophagitis and myasthenia gravis, are also known contributors (Marik ). Dogs have been reported to have many of the same predisposing risk factors as humans, with the additional major category of recent vomiting and regurgitation (Strombeck & Harrold , Wilson & Walshaw , Kogan et al , , Ovbey et al , Garcia et al ). Similar predisposing factors were revealed in this population of cats with aspiration pneumonia, with recent vomiting and recent anaesthesia being the most common.…”

Objectives To describe the clinical syndrome of aspiration pneumonia in cats and record potential predisposing factors. Materials and Methods A retrospective medical records search for cats with a diagnosis of “aspiration pneumonia” or “bronchopneumonia” was performed. Cases were included if they had a complete medical record and three‐view thoracic radiographs with pulmonary changes consistent with aspiration pneumonia and no other radiographic or physical examination findings suggestive of another cause of pulmonary or cardiac disease. Results We identified 28 cases. Potential predisposing conditions included: vomiting (12 of 28; 43%), anaesthesia (five of 28; 18%), enteral nutrition (five of 28; 18%), preexisting oesophageal disease (four of 28; 14%), neurologic disease (two of 28; 7%) and laryngeal disease (one of 28; 3.6%); 15 of 28 (53%) had more than one potentially predisposing condition. The most common lung lobe affected was the right middle (18 of 28; 64%), followed by the left cranial (16 of 28; 57%); multiple lung lobes were affected in 16 of 28 (57%) cases. Most cats (25 of 28; 89%) survived to discharge, with a median hospitalisation of 3 days. Clinical Significance Potential predisposing factors for developing aspiration pneumonia in cats are similar to those recorded in dogs and people. Aspiration pneumonia occurred in cats following vomiting, anaesthesia or after receiving enteral nutrition. Survival rates are high following treatment with antibiotics and supportive care, with 89% of cats in this study surviving to discharge.

“…Morphine, oxymorphone, and hydromorphone are frequently utilised as premedications in dogs and cause a high incidence of vomiting [23,38], which may lead to aspiration pneumonia [38,39]. In humans, vomiting is considered one of the main anaesthetic complications and is associated with a high incidence of intubation and acute respiratory distress syndrome (ARDS) [37].…”

“…In humans, vomiting is considered one of the main anaesthetic complications and is associated with a high incidence of intubation and acute respiratory distress syndrome (ARDS) [37]. In veterinary medicine, there are few published reports of this post-anaesthetic complication, although it has recently been shown to have a much higher incidence in animals (0.17%) than in humans (0.014 – 0.05%) [39]. …”

Evaluation of the effects of methadone and tramadol on postoperative analgesia and serum interleukin-6 in dogs undergoing orthopaedic surgery

BackgroundAcute postsurgical pain is of great interest due to potential risk of becoming chronic if not treated properly, worsening patient’s recovery and quality of life. Twenty-eight dogs with ruptured cruciate ligaments were divided into three groups that received intramuscular injections of 4 mg/kg of tramadol (TRA), 0.5 mg/kg of methadone (MET0.5), or 0.7 mg/kg of methadone (MET0.7). Physiological parameters (heart and respiratory rates and blood pressure) were evaluated at specified times: baseline (TBL), 1 (T1), 2 (T2), 4 (T4), 6 (T6), and 24 (T24) hours after premedication. Pain scores were described by visual analogue scale (VAS), modified Glasgow Composite, and Colorado University Acute Pain scales. Blood samples for measurement of interleukin (IL)-6 were collected at TBL, T1, T6, and T24. This was a prospective, randomised investigation to evaluate the efficacy of tramadol and methadone as premedications in dogs undergoing osteotomies.ResultsThere were no statistically significant differences between groups with respect to age, weight, gender, surgery time, and time to extubation. Heart rate, respiratory rate, and blood pressure values were maintained within acceptable ranges, and a reduction was observed at T2 in MET0.5 and MET0.7 compared with TBL. Increases in VAS scores were observed in TRA at T4 compared with TBL, T1, and T24 and between T1 and T6 (p < 0.001). In MET0.5, there was significant increase in VAS score at T4 compared with T1 (p < 0.001). TRA and MET0.5 showed significantly higher mean ± SD VAS scores (3.4 ± 2.5 and 2.5 ± 2.6, respectively) than MET0.7 (1.1 ± 1.5) at T4 (p < 0.001). TRA showed greater demand of rescue analgesia (four animals in T4 and two in T6) (p < 0.037). There were no statistically significant differences in sedation scores, Colorado Scale scores, or interleukin levels between groups and time points.ConclusionsMethadone given as premedication in doses of 0.7 mg/kg was better at controlling pain compared with lower doses and tramadol. However, dosage increases, administered as rescue analgesia, promoted adequate pain control even in tramadol group. Influence of these analgesics on IL-6 release could not be demonstrated, but significant levels were not found.Electronic supplementary materialThe online version of this article (doi:10.1186/s12917-014-0194-7) contains supplementary material, which is available to authorized users.

“…Regurgitation is the passive ejection of gastric or esophageal content from the mouth or nose. Despite the low incidence of such disorder in anesthetized dogs without preexisting predisposing disease, aspiration pneumonia has been reported with an incidence of 0.17–26% . Studies in anesthetized dogs have shown a variable prevalence of GER ranging from 4.8 to 55%, depending on factors related to the patient, duration and type of surgical procedure, and drugs used during the anesthetic process.…”
