Managing passive regurgitation in patients under general anaesthesia

In orthopaedic practice, an increase in incidence of gastro-oesophageal reflux reported in patients undergoing surgery has been recognised. Possible causes include longer anaesthesia duration, patient...

Propofol wastage in anaesthesia: implications and environmental outcomes

A labelled box was placed in the hospital prep room and all staff were asked to dispose of any waste propofol syringes into the box once they had finished their anaesthetic and handed their patient...

Fluid therapy for emergent and critical cases: hypovolaemia vs dehydration

King and Boag (2018) stated that the average patient's body weight is made up of the weight of dry matter (40%), such as tissues and bones, and also fluid (60%). Fluid can then be further subdivided...

The importance of peri-anaesthetic temperature management: part 2

Commonly a result of an inability to dissipate heat, increased heat production/provision or a combination of both, hyperthermia can have significant deleterious impacts on the body (Thomson et al,...

The recovery period

Although relatively new in veterinary medicine, anaesthesia checklists in human medicine have been shown to decrease complications and mortality rates (Hohenfellner, 2009) by reducing the occurrence...

The importance of peri-anaesthetic temperature management: part 1

Inadvertent perioperative hypothermia is a common complication of anaesthesia and sedation, although the seriousness of its effects should not be overlooked despite its frequent occurrence (Reynolds...

Anaesthetic considerations for a bleeding hemangiosarcoma undergoing splenectomy

On presentation to the practice the patient should have their basic parameters assessed, including heart rate, respiratory rate, temperature, mucous membrane colour, capillary refill time and blood...

Bypassing their way into your heart: considerations for the cardiothoracic patient

Therapeutic hypothermia is applied via cooling of the blood in the cardiopulmonary bypass machine (Kanemoto, 2014). This reduces the metabolic rate and oxygen demand from the tissues reducing risk of...

Capnography for the veterinary nurse

CO2 within the body can be measured either directly via arterial sampling, which gives us the partial pressure of CO2 in arterial blood (PaCO2), or indirectly via capnography. PaCO2 readings are...

Postoperative care of brachycephalic patients: airway management and cardiovascular support

An assessment of cardiovascular function in the patient can easily be performed using subjective methods such as mucous membrane colour, capillary refill time, pulse rate and quality, peripheral and...

Anaesthetic management of caesarean sections in dogs

The anaesthetic plan must aim for maternal and neonatal survival, presenting a unique challenge to the anaesthetist. Exposure of the fetuses to anaesthetic drugs, since many cross the placenta...

Pre-anaesthesia preparation in cats and dogs – recent evidence

Although this paper focuses on pre-anaesthesia preparation, it is important to understand factors that affect complications related to anaesthesia. Several studies have been published determining the...
