An estimated 43% of total blood volume was lost during craniectomy in a 32‐kg Labrador retriever. One episode of bradycardia, followed by ventricular tachycardia occurred during surgery when the rate of haemorrhage exceeded fluid replacement. Sinus rhythm was re‐established with intravenous lidocaine (1.25 mg kg?1). Twenty‐four hours later, premature ventricular complexes appeared followed by episodes of ventricular tachycardia, some requiring lidocaine treatment. Myocardial hypoxia resulting either from hypovolaemia and/or air embolism (the right transverse venous sinus was damaged during surgery) may have caused the arrhythmias. Mild intracranial hypertension may have aggravated the problem. 相似文献

Babesia argentina, Babesia bigemina and Theileria mutans were transmitted experimentally from water buffaloes (Bubalus bubalis) to splenectomised Bos taurus calves. Buffaloes were positive to an indirect fluorescent antibody test for B. argentina when reagents of bovine origin were used. The formation of similar patterns during immunoelectrophoresis suggested a homology of buffalo and bovine serum proteins, particularly IgG. 相似文献

Objective – To describe the management and outcome of a dog presenting with intractable seizures associated with traumatic brain injury. Case Summary – A spayed female Wheaten Terrier was presented to an emergency clinic with neurologic deficits (modified Glasgow coma scale of 10) shortly after a road traffic accident. Seizures were uncontrolled despite aggressive pharmacologic intervention. Controlled hypothermia to achieve a rectal temperature of 33–35°C (91.4–95°F) was initiated as a protective measure to reduce intracranial pressure and cerebral metabolic rate, and to assist with seizure control. Intubation and mechanical ventilation were required to protect the airway and manage hypercapnia associated with hypoventilation. The patient went on to make a full recovery, although behavioral changes were noted by the owners for an 8‐week period following injury. New or Unique Information Provided – To the author's knowledge, this is the first instance of therapeutic hypothermia reported in the veterinary literature. A short review of this treatment modality is provided. 相似文献

Objective— To define a safe corridor in the dorsoventral plane within the feline sacral body for placement of screws inserted in lag fashion for repair of sacroiliac luxation.
Study Design— Anatomic study.
Sample Population— Frozen cadaveric feline sacra.
Methods— Feline sacra (n=20) were used to perform a radiographic study to define a safe corridor to a depth of 66% of the sacral body width. Two drill start points (A and B) were evaluated. Dorsal exit from the safe corridor was considered unacceptable.
Results— Forty safe corridors were measured. The mean articular surface was 100±6.4° from horizontal. Mean maximum, optimum, and minimum safe corridor drill angles from drill point A were 107±6.8°, 97±6.9°, and 87±7.2°, respectively, from the articular surface. Mean maximum, optimum, and minimum angles from drill point B were 109±7.2°, 99±7.1°, and 89.5±7.2°, respectively. Point B increased the risk of ventral exit from the sacral body.
Conclusions— Point A and a drill angle of 90±4° for drilling of the feline sacral body is recommended. This margin for error risks ventral exit from the body in 23/40 (58%) of the sacra in this study. Reduction of the margin for error to ±2° would reduce the risk of ventral exit to 14/40 (35%) of the sacra in this study.
Clinical Relevance— Drilling at 90° to the feline sacral articular surface is recommended. Findings from this study present a strong case for use of angled drill guides. 相似文献

Fatty acid alkyl esters (FAAEs) are a family of natural neutral lipids present in olive oils and formed by esterification of free fatty acids (FFAs) with low molecular alcohols. Inappropriate practices during the olive oil extraction process and bad quality of the olive fruits promote their formation. Quantification can be done by isolation with a silica gel solid phase extraction cartridge followed by analysis on a gas chromatograph equipped with a programmed temperature vaporizer injector using a polar capillary column. The application of the method to more than 100 Spanish olive oils from different categories, varieties, and geographical origin allowed for establishing the average content of FAAEs and distinguishing the Spanish protected denomination of origin (PDO) and extra virgin olive oils from other categories of olive oils. Those other categories of oils can be subjected to a mild refining process, which leads to blending with extra virgin olive oils. Studies on low quality oils subjected to mild refining showed that FAAEs remain after that process. Thereby, blends of extra virgin olive and mildly refined low quality olive oils can be detected by their alkyl ester concentrations. 相似文献

Objective— To evaluate the effect of fracture and subsequent repair on future bone growth of the humerus after Salter–Harris type IV fracture of the lateral part of the humeral condyle (LPHC).
Study Design— Prospective study.
Animals— Dogs (n=11).
Methods— Dogs that had LPHC fracture and an open distal humeral physis repaired (1992–2006) were re-examined and radiographed at ≥12 months of age and humeral length was measured.
Result— Measurements from 11 dogs showed a significant ( P =.02) increase in length of the humeral diaphysis of the affected leg compared with that of the intact limb (median, 1.2%; range, 1.3–3.4%). Condylar deformity secondary to growth disturbance was not observed.
Conclusion— Shortening or growth deformity was not observed after fracture and repair even if a transcondylar screw was placed through the distal humeral growth plate. A mild overgrowth of the humeral diaphysis was observed, although likely considered clinically unimportant.
Clinical Relevance— Fracture of the LPHC and subsequent repair in dogs >3 months of age do not impair growth of the humeral diaphysis. A transcondylar humeral screw placed through the humeral physis will not result in shortening of the humeral diaphysis. Implant removal to allow for further growth is therefore not indicated. 相似文献

Objective— To report clinical findings, treatment, and outcome in dogs with acute (<7 days) oropharyngeal or esophageal stick injury. Study Design— Retrospective study. Animals— Dogs (n=41) with acute oropharyngeal or esophageal injury. Methods— Dogs had clinical and radiographic examination, and frequently, cervical surgical exploration. The decision to operate was based on radiographic findings of cervical emphysema. Outcome was determined by owner or veterinarian interview. Results— Of 41 dogs, 27 had oropharyngeal injury and 14 had esophageal injury. Five dogs with esophageal injury died. All dogs with radiographic evidence of cervical emphysema (n=34) had ventral median cervical exploration or necropsy; 11 had wood fragment(s) retrieved. In 7 dogs without radiographic signs of cervical emphysema, wounds involving the pharynx or soft palate were treated by local debridement and lavage using an oral approach. Mean follow‐up time was 36.4 months. All wounds healed without complication; however, 1 dog that was not surgically explored had a piece of wood surgically retrieved 3 months later. Conclusions— Radiographic evidence of cervical emphysema is a frequent finding in dogs with acute penetrating oropharyngeal or esophageal injury and indicates trauma to the deeper cervical tissues. Acute penetrating injury of the oropharyngeal region, when treated appropriately, has a better prognosis than acute esophageal penetration. Clinical Relevance— Ventral median cervical surgical exploration is recommended in dogs with acute penetrating injury of the oropharynx or esophagus if there is radiographic evidence of tissue emphysema. 相似文献

Laryngeal paralysis in horses has been reported after inhalational anesthesia and can result in significant morbidity/mortality. The cause of the condition is unclear. The objective of this study was to examine the effects of a standardized anesthetic protocol on laryngeal function and laryngeal/pharyngeal trauma in the peri-anesthetic period in a prospective study. A 30- to 60-second digitalized video clip of laryngeal movement from a standardized endoscopic view was recorded at five time points: before sedation, post-sedation, post-induction, immediately after recovery to standing, and at 24 hours after recovery. A standardized anesthetic regimen was used in all cases. Video clips were randomized and evaluated by two blinded assessors. Each assessor scored each clip for laryngeal function and trauma using previously validated scoring systems. Agreement between assessors was calculated using the mean of the five time-specific weighted kappa statistics. Post-anesthesia laryngeal function and trauma scores were compared with initial scores using the Wilcoxon signed rank test with Bonferroni adjustment. Spearman's rank coefficient was used to assess correlation between trauma and function scores and between anesthetic duration and laryngeal function and trauma scores.There was no significant effect of anesthesia on laryngeal function. Trauma scores were not significantly higher after tracheal intubation. The trauma scoring system requires further validation. There was no correlation between higher trauma scores and laryngeal function or duration and laryngeal function or trauma.Further work is required to evaluate other variables that may affect laryngeal function after anesthesia, using a larger number of horses with varying degrees of laryngeal dysfunction. 相似文献

Objective – The aim of this article is to review Angiostrongylus vasorum infection in dogs, including the life cycle, signalment, clinical signs, diagnosis, and treatment. Apparent changes in the epidemiology of this unique parasite are considered, alongside information available regarding its recent geographic spread.
Etiology – A. vasorum is a metastrongyloid parasite capable of causing an array of clinical problems in dogs, including cardiorespiratory, coagulopathic, and neurologic signs. Currently, the parasite has a worldwide distribution; however, it usually arises in small pockets of enzootic foci. Recent reports suggest a changing distribution of this parasite, which has renewed interest in its epidemiology and in the risk of expansion to new areas including mainland North America.
Diagnosis – A definitive diagnosis of angiostrongylosis is usually made using the modified Baermann technique either using feces or tracheobronchial secretions; however, this review also discusses novel methods such as serologic and molecular techniques.
Therapy – Once a diagnosis of angiostrongylosis is made, prompt treatment should follow with anthelmintic drugs (such as moxidectin/imidacloprid, milbemycin oxime, or fenbendazole) and supportive care dependent upon the patient's clinical signs. Currently, there is no proven prophylactic regime.
Prognosis – The prognosis appears to be very dependent upon the severity of clinical signs at presentation. A. vasorum can be fatal and death may be sudden. However, if a prompt diagnosis is made and appropriate treatment is administered complete clinical resolution is possible. 相似文献
