“…Measurement of the cardiac output could have been interesting for a better understanding of the cardiac performance. However, in the presence of a VSD none of the indicator dilution techniques can be used to determine cardiac output (Hallowell and Corley 2005, Kutter and others 2016). Alternatively, oesophageal echocardiography could have been used to estimate the cardiac output (Young and others 1996), perianaesthetic shunt fraction and cardiac contractility, but it was not available in this case.…”

A 2 years and 11 months old Belgian draught horse stallion with a membranous ventricular septal defect, severe aortic regurgitation, mild left ventricular enlargement and ventricular premature depolarisations was anaesthetised to perform open castration. A balanced anaesthetic approach, involving intravenous use of romifidine (80 µg/kg), morphine (0.1 mg/kg) and lidocaine (1 mg/kg) for premedication, followed by induction of anaesthesia with ketamine (2.2 mg/kg) and midazolam (0.06 mg/kg) and maintenance with isoflurane, lidocaine CRI (50 µg/kg/min) and intratesticular lidocaine 2 per cent (10 ml in each testicle) was used to optimise the cardiovascular stability and enhance the safety of the procedure. A multimodal analgesic approach was provided, aiming to reduce the amount of isoflurane required to maintain a surgical plane of anaesthesia. A smooth and uneventful recovery was obtained. The present case report describes an anaesthetic protocol that could be applied in similar cases.

“…Monitoring CO during equine anaesthesia is mainly reserved for research (Kutter et al., 2016). Despite this, CO measurement may enable guided fluid resuscitation and choice of cardiac support drugs during general anaesthesia (Corley et al., 2003) yet is rarely done in practice.…”

“…Most devices require repeated calibration with lithium dilution or thermodilution techniques (Bendjelid, 2009). Conflicting evidence exists regarding the accuracy of devices in anaesthetised horses and foals (Hallowell & Corley, 2005; Schauvliege et al., 2009; Shih et al., 2009) with noncalibrated devices proving inaccurate (Kutter et al., 2016). Routine clinical use of pulse contour analysis cannot currently be recommended.…”

The anaesthetist aims to preserve normal physiology of the horse notwithstanding the use of general anaesthetic drugs and pre-existing pathological changes. Provision of analgesia and maintaining an adequate plane of anaesthesia are important alongside monitoring cardiorespiratory performance, response to noxious stimuli and temperature. There are a variety of techniques that subjectively or objectively assess physiological variables, and the results should be interpreted in the context of the anaesthetic protocol. Basic 'hands-on' monitoring of anaesthesia requires no equipment and is a core skill for every anaesthetist. However, as technology advances, many more electronic monitoring options have become available. This review describes how to use specific monitoring techniques, discusses the evidence underpinning them and evaluates their place in clinical practice. Where appropriate, normal and abnormal values are highlighted, although evaluation of trends may be more important in some cases. Regular documentation of variables enables trends to be identified and is key to appropriate early intervention. All basic monitoring techniques that require no equipment, such as ocular and mucous membrane assessment and pulse palpation, are recommended for every general anaesthetic procedure. The use of capnography, pulse oximetry, electrocardiography and blood pressure monitoring devices is recommended where indicated (Martinez et al., 2008), recognising that anaesthesia in horses is performed in a variety of places with different facilities and using various drug combinations.
