Roessner","doi":"10.1111/eve.14198","DOIUrl":"https://doi.org/10.1111/eve.14198","url":null,"abstract":"&lt;p&gt;The case report by Papa et al. (&lt;span&gt;2025&lt;/span&gt;) describes the successful management of a ureteral tear in a foal. While the foal in this case report did well under anesthesia, this article highlights several important patient factors that can lead to cardiopulmonary arrest under general anesthesia.&lt;/p&gt;&lt;p&gt;Foals under 1 month of age are particularly susceptible to complications under general anesthesia with an increased risk of death compared to adults (Johnston et al., &lt;span&gt;2002&lt;/span&gt;). Multiple case reports have demonstrated that perianaesthetic cardiac arrest can be successfully managed in foals (Haga et al., &lt;span&gt;2011&lt;/span&gt;; Marolf et al., &lt;span&gt;2018&lt;/span&gt;; Wiechert-Brown et al., &lt;span&gt;2022&lt;/span&gt;). In 2024, the RECOVER Initiative published an updated version of its Cardiopulmonary Resuscitation (CPR) guidelines, incorporating revised recommendations (Burkitt-Creedon et al., &lt;span&gt;2024&lt;/span&gt;). This clinical commentary aims to present these recommendations in the context of perianaesthetic cardiopulmonary resuscitation in foals.&lt;/p&gt;&lt;p&gt;Cardiopulmonary arrest (CPA) in foals is most commonly described due to patient-related factors surrounding parturition, such as prematurity or dysmaturity, asphyxia and neonatal maladjustment. CPA in anaesthetised foals can be due to a combination of anaesthetic or patient-related factors.&lt;/p&gt;&lt;p&gt;Signs of impending cardiopulmonary failure in anaesthetised patients include hypotension (&lt;40 mmHg), marked elevations in lactate, apnoea, agonal breathing, absent peripheral pulses, nonresponsive mydriatic pupils, bradycardia or tachycardia. In anaesthetised patients, detection of CPA is typically characterised by a loss or sudden severe reduction of end tidal CO&lt;sub&gt;2&lt;/sub&gt; (EtCO&lt;sub&gt;2&lt;/sub&gt;), hypotension and loss of arterial waveform, as well as cardiovascular rhythms associated with CPR, such as asystole, ventricular fibrillation and pulseless ventricular tachycardia. Often, CPR is initiated earlier in those who are anaesthetised and is associated with higher survival rates, likely due to the rapid response, presence of monitoring and previously established venous and airway access.&lt;/p&gt;&lt;p&gt;Basic life support (BLS) encompasses airway management, ventilation and chest compressions, forming the foundation of effective cardiopulmonary resuscitation (CPR). BLS is performed in 2-min cycles.&lt;/p&gt;&lt;p&gt;Advanced life support (ALS) involves pharmacologic interventions and advanced monitoring in addition to BLS to address the underlying causes of CPA and support ROSC. Drug dosing is available in Table 1.&lt;/p&gt;&lt;p&gt;Effective CPR in neonatal foals hinges on prompt recognition of CPA, initiation of BLS measures, including airway management, ventilation and chest compressions, followed by ALS interventions tailored to the foal's specific needs. Adherence to current RECOVER guidelines and continuous monitoring can enhance the likelihood of ROSC and improve survival outcomes. Ongoing research and training are crucial for refining","PeriodicalId":11786,"journal":{"name":"Equine Veterinary Education","volume":"37 11","pages":"563-567"},"PeriodicalIF":0.8,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://beva.onlinelibrary.wiley.com/doi/epdf/10.1111/eve.14198","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monitoring equine pregnancy can be challenging, owing to the size of the equine abdomen (precluding visualisation of the entire fetoplacental unit), individual variation in the appearance of the reproductive tract, and (typically) minimal clinical signs of pregnancy compromise until late in a disease process. A large proportion of currently available literature regarding medication use in the pregnant mare focuses on those pharmaceuticals which may be of use in treating placentitis, leaving the practitioner to extrapolate from these findings when managing clinical cases that do not fit into a tidy diagnosis; the aim of this paper is to aid the practitioner with making rational choices of medications using evidence-based medicine, while simultaneously considering a One Health perspective.

{"title":"Back to basics: Hoof pastern conformation and its role in development of pathology within the coffin joint","authors":"M. A. Smith","doi":"10.1111/eve.14199","DOIUrl":"10.1111/eve.14199","url":null,"abstract":"&lt;p&gt;Warmbloods and Warmblood cross-breeds make up a high proportion of sports horses in active competition work in the Western world. As a breed, Warmbloods often have small feet relative to their body size and weight, resulting in proportionally increased load on structures within the hoof capsule. This may predispose to some patterns of pathology, resulting in lameness that can be localised to within the foot. The paper by Carrozzo et al. (&lt;span&gt;2025&lt;/span&gt;) presents an &lt;i&gt;uncommon&lt;/i&gt; variation of a common pathology, namely osteoarthritis of the distal interphalangeal joint (DIP), in a small number of Warmblood horses all working competitively at a high level within the showjumping industry.&lt;/p&gt;&lt;p&gt;The propensity for many horses to be ‘broken back’ in hoof pastern conformation, with a long toe and low heel conformation extends the point of breakover further dorsal relative to the long axis of the distal limb and places greater loading forces onto the dorsodistal aspect of the middle phalanx and the extensor body and extensor process of the distal phalanx. Therefore, a ‘broken back’ conformation as well as a high workload may explain why lameness clinicians routinely see modelled articular margins, new bone formation and areas of sclerosis (radiographs and MRI) or abnormal fluid accumulation (‘oedema’ on MRI) within the trabecular bone of the dorsal aspect of these osseous structures within the dorsal recess of the DIP joint (Figure 1), rather than modelling within the palmar recess of the DIP joint.&lt;/p&gt;&lt;p&gt;A ‘broken back’ hoof pastern conformation also results in the palmar flexor compacta of the navicular bone becoming liable to greater compressive force from the deep digital flexor tendon, with pathology we might expect to see on MR images including abnormal increased fluid/necrosis signal within the navicular spongiosa and focal concavities in contour representative of erosive lesions extending within the flexor compacta (Figure 2).&lt;/p&gt;&lt;p&gt;Increased compressive forces between the two adjacent articular surfaces of the palmar distal aspect of the middle phalanx and the dorsal margin of the navicular bone due to increased load from proximal, perhaps secondary to repeated jumping effort rather than solely due to increased shearing forces secondary to DDFT compression may be a contributing cause of the relatively rare occurrence of osteoarthritis primarily within the palmar recess of the DIP joint reported in the accompanying paper. The authors note the need for further research investigating conformation as a potential cause of increased forces between the articular surfaces of the middle phalanx and the navicular bone.&lt;/p&gt;&lt;p&gt;It is interesting to note that in the three cases presented there appears to be little evidence of modelling within the dorsal recess of the DIP joint despite the extensive changes described within the palmar recess.

Ultrasonographic examination revealed synovitis of the CB and tearing of the <i>gastrocnemius</i> tendon (GT) in both horses. Additionally, desmitis of the medial <i>retinaculum</i> and a focal area of radiolucency on the plantar border of the <i>calcaneus</i> were also identified in Case 2.
