Topic:Emergency Care
Emergency care in horses involves the immediate assessment and treatment of acute medical conditions or injuries to stabilize the animal and prevent further harm. This area of veterinary practice encompasses a range of situations, including colic, traumatic injuries, respiratory distress, and sudden lameness. Emergency care procedures may involve physical examinations, diagnostic imaging, fluid therapy, pain management, and, in some cases, surgical intervention. This topic includes peer-reviewed research studies and scholarly articles that explore the methods, protocols, and outcomes associated with emergency interventions in equine medicine.
Non-surgical management of rectal tears in two mares. Two mares presented with life-threatening rectal tears were successfully treated with intensive medical management. Although surgery has been regarded as mandatory for grade 3 or 4 rectal tears in the past, recent reports have indicated the value of medical management alone. The case reports presented in this article detail the use of antibiotics, flunixin meglumine, laxative diets and faecal softeners in the medical management of two mares presented with grade 3 rectal tears.
Predictive values, sensitivity and specificity of abdominal fluid variables in determining the need for surgery in horses with an acute abdominal crisis. To determine the predictive values, sensitivity and specificity of abdominal fluid variables associated with the need for surgery in horses with an acute abdominal crisis. Methods: Retrospective study. Methods: Two-hundred and thirty-six horses examined for signs of abdominal pain between January 1993 and June 1999. Methods: Breed, age and gender of the horse and colour, total protein concentration and total nucleated cell count of an abdominal fluid sample were recorded. Colour of the abdominal fluid was classified as normal if it was yellow and transparent. Turbid fluid or fluid that was ser...

[Intoxication with propylene glycol in two horses]. Two horses were accidentally administered propylene glycol instead of mineral oil. After discovery of the mistake intensive medical therapy with intravenous fluids, etc. was started, and both animals recovered fully from their clinical symptoms. Veterinarians use propylene glycol as well as paraffin routinely for the treatment of their patients. Mistakes are likely to be made because both medicines and sometimes their packing have a similar appearance. Several incidents have been reported in other countries. A large amount of propylene glycol given to a horse, but also to other animals, can be...
Laparoscopic intra-abdominal ligation of the testicular artery following castration in a horse. A 364-kg (800-lb) 1-year-old mixed-breed horse was admitted for treatment of uncontrolled bleeding after castration. Multiple attempts to ligate the testicular artery through the scrotal incisions prior to referral had been unsuccessful. Because of the owner's concerns about cost, an attempt was made to control the bleeding by applying pressure to the inguinal region and administering formalin IV. However, hemorrhage continued. A decision was made to use laparoscopy to ligate the testicular artery. The horse was anesthetized and positioned in dorsal recumbency, and a routine ventral laparoscop...
Mechanisms and patterns of injuries related to large animals. Injuries from encounters with large animals represent a significant health risk for rural communities. We evaluated our regional trauma centers' experience with large-animal injuries to determine whether certain mechanisms and patterns of injury predicted either major head/craniofacial or torso (chest/abdomen/pelvis) trauma. Methods: The hospital courses of 145 patients with injuries related to large animals were reviewed retrospectively to determine patterns of injury, specific injury mechanisms, species-specific injuries, and predictors of multiple body region trauma. Results: Seventy-nine p...

The comparative analysis of patient samples with routine methods showed a very strong positive correlation with correlation coefficients above 0.96 for blood gases, pH, glucose, urea, hemoglobin, hematocrit, sodium and potassium, with the exception of chloride where it was 0.867. The i-STAT syste...
[Animal bites at the casualty department of the Oslo City Council]. During a 2-year period all Casualty Department data charts with the diagnosis "animal bite" were reviewed as part of internal quality control. Of 1,051 recorded episodes, 503 (48%) were women and 147 (14%) children under 16 years of age. 951 (90%) wounds were treated without closure. Half of the patients were not given antibiotics on the first visit, whereas one third were given penicillin. Tetanus status had been evaluated on 1,015 (97%) charts. Most bites were caused by dogs (76%), cats (17%), and horses (2%). Children were the victims of 118 (15%) dog bites, eight (4%) cat bites, and ten (5...
[Contribution to the treatment of displacement of the ascendant colon in the spleen-kidney area]. Objective to this field study was to find an alternative to rolling a colic patient with left dorsal displacement under general anesthesia. For that purpose a total of 49 horses with a complete nephrosplenic entrapment out of 542 colic patients presented at the Tierklinik Kerken in 1996 were retrospectively evaluated. Having performed a preliminary colic examination and initial treatment if needed, horses which did not undergo surgery immediately where left loose in a small sized arena to move and roll themselves under observation. According to the results of further exams, horses were left in...
A retrospective study of mortality associated with general anaesthesia in horses: emergency procedures. A retrospective study evaluated 995 emergency equine general anaesthetics. The total mortality for emergency procedures was 31.4 per cent. This figure was examined in more detail to determine if all emergency procedures carried a similar risk. Horses anaesthetised for surgical colic had an increased risk of death or euthanasia, with a total mortality of 35.5 per cent when compared to horses anaesthetised for non-colic related problems which had a total mortality of 15.3 per cent. The findings of this study illustrate the greatly increased risk of mortality in horses undergoing general anaesthe...
Recidivism in equestrian trauma. A 3-year chart survey and questionnaire was conducted of equestrian-injured patients at a regional trauma center to determine patterns and consequences of injury and rate of recidivism. Ninety-two patients (95 encounters) were treated; most were young (mean age, 27 +/- 11 years) women (84%) riders sustaining falls (80%). Most injuries were orthopedic (47%); 19 per cent of patients required hospital admission. There was one death. Helmet use was documented in only 34 per cent. Eighty-one per cent of patients responded to a follow-up telephone survey; 36 per cent recounted additional accidents (...

Major pelvic injuries in equestrian sports. A series of pelvic and acetabular injuries caused by horse riding accidents is reported. The importance of wearing appropriate protective clothing when riding is emphasised.
Advances in diagnostic techniques for horses with colic. Recent advances in the use of abdominal ultrasound, endoscopy, laparoscopy, radiography, and peritoneal fluid analysis have contributed to the evaluation of horses with colic. Improved diagnostic capabilities allow earlier surgical intervention when necessary, and this should improve survival rates and the economic aspects of case management.
Management of rectal tears. Rectal tears have important medicolegal implications, and severe tears have a poor prognosis. Prompt diagnosis, immediate application of first aid measures, early referral, use of appropriate definitive treatments, and aggressive aftercare will improve the prognosis. The grade of rectal injury will determine the definitive treatment, but there are few guidelines to determine which treatment is best in each case. Bypass procedures, such as colostomy and indwelling rectal liner, have their own advantages and disadvantages, but can facilitate healing and prevent life-threatening complications if ...
