Ask VETbytes: What are the treatment aims of head trauma/traumatic brain injury?

This week, we asked VETbytes: “what are the treatment aims when managing a case with head trauma or traumatic brain injury?”. After your initial assessment, our vets recommend the following treatment aims, but first, remember:

Cerebral perfusion pressure = MAP – ICP
If ICP > MAP there is no cerebral perfusion

Optimise MAP
  • i/v fluids
  • +/- blood products
  • +/- vasopressor support
Reduce ICP
  • Avoid hypoxaemia
  • Avoid hypercapnia or hypocapnia
  • Promote venous drainage by elevating the upper body by 15–30 degrees
  • Manage seizures
  • Control pain
  • Reduce cerebral oedema with hypertonic saline or mannitol

Ask VETbytes: Acute Haemorrhagic Diarrhoea Syndrome

This week we were asked if antibiotics are indicated in cases of canine acute haemorrhagic diarrhoea syndrome (AHDS)? Our team of vets had the following advice:

  • Routine use of antibiotics is not recommended
  • Treatment of dogs with aseptic haemorrhagic gastroenteritis with co-amoxiclav does not reduce the time to resolution of clinical signs
  • Evidence suggests that the addition of metronidazole is not beneficial
  • Broad-spectrum i/v antibiotics are indicated in immunocompromised or neutropenic patients and in those with suspected sepsis
  • Stop antibiotics as soon as the patient is clinically well

Latest update: how do you diagnose a colonic torsion?

One of the many VETbytes features is its ‘latest evidence’ feed, which provides a snapshot of the latest evidence in bitesize form, recently added to the emergency and critical care module.

Rapid identification of colonic torsion is imperative to prevent significant ischaemic injuries.

A new study by Czajkowski and Fryer,* describes a rapid, low morbidity test that can be used in cases of suspected colonic torsion in dogs which may help to differentiate this rare condition from generalised ileus or small intestinal volvulus.

To view the full evidence feed and find out how to recognise a colonic torsion in your patients, sign up for a free trial of the VETbytes emergency and critical care module or subscribe for an annual licence for only £99/year!

Ask VETbytes: Post-operative pain relief options for dogs and cats undergoing caesarean section

Ask VETbytes

In our new feature ‘Ask VETbytes’, our team of vets will be answering your questions. This week we were asked “What are the options for post-operative pain relief in dogs and cats undergoing caesarean section?”

This is an area where veterinary evidence is lacking and where our patients don’t always receive adequate analgesia, so we have drawn on both human studies and specialist veterinary consensus to create a practical guide for you and your patients:

  • Despite the paucity of published evidence regarding the safety of analgesic drugs in the pregnant or lactating dog and cat it is important to recognise our responsibility to the welfare of our patients regarding the provision of adequate analgesia10
  • It is estimated that the neonate receives approximately 1–2% of the maternal dose of a drug14
  • A longer acting opioid injection may be administered after all the foetuses have been removed e.g. methadone 0.1–0.2 mg/kg10,41
  • In women, NSAIDs are considered safe and effective analgesia after caesarean section because of their low excretion in breast milk38,40
    The same is considered likely to apply to dogs and cats due to the known physiochemical properties of the drugs13,14
    A single dose administered in the immediate postoperative period is generally advocated10,14
    Consider ongoing administration, as required, for 1-2 days after discharge13
  • Paracetamol is generally considered safe in dogs14 
  • NSAIDs should only be administered if the bitch/queen is normovolaemic and normotensive13
  • Paracetamol should NOT be used in cats14
  • None of these drugs are licensed for lactating bitches or queens, ensure that prior owner consent is obtained for their use

Don’t stress: VETbytes offers vital stress relief for emergency vets

Emergency and critical care work can be stressful and demanding, and rising caseloads are contributing to more cases of burnout in the veterinary profession. With the application of evidence-based veterinary medicine, VETbytes offers a stress-relief manifesto.

A new survey conducted by the British Veterinary Association has found that three-quarters of vets are concerned about stress and burnout, with the small animal vet category ‘most concerned’ – a situation compounded by the coronavirus pandemic.

Emergency medicine has the added stress of long work hours, an intense work environment with pressure to efficiently identify clinical needs and manage client expectations. Being able to access the best clinical guidance in emergency situations can be a key factor in managing stress levels and improving patient outcomes.

The emergency and critical care app from VETbytes was created as a clinical support tool for veterinary teams, providing evidence-based veterinary information in concise clinical guides. Vets can now also access the ‘latest updates’ feature to seamlessly stay up to date with the latest findings in ECC.

“VETbytes exists to bring evidence-based medicine to the fore of veterinary general practice,” said Zoë Coker and Bronwen Eastwood, co-founders of VETbytes. “Now is a crucial moment for vets to take action to help reduce stress levels, VETbytes offers a cost-effective and simple way to do this.”

VETbytes provides clear benefits to clinicians such as more efficient case management and reduction of errors and stress, which are especially important during the pandemic.

VETbytes is accessible on mobile, iPad and desktop. The latest evidence added to the ECC app is available to view here.

Podcast Interview: What Vetbytes? Bronwen, Brighton and Belize

Scott Kilpatrick, director (Internal Medicine) at veterinary thought exchange chatted to Bronwen Eastwood, Co-Founder of VETbytes earlier this week for the vtx podcast. Click here to listen to the full interview and hear Bronwen’s amazing career that has taken her from Brighton to Belize and back again!

In the interview, Bronwen explains how she went on to co-found VETbytes, after recognising a void for a resource that provides up-to-date, evidence-based, user-friendly clinical information. Alongside co-founder Zoe Coker, Bronwen co-wrote some of the treatment guides for the VETbytes emergency and critical care app, a subscription-based resource designed to support vets who need to keep up to date and provide an excellent service to their clients and patients. 

Updates feed launched to help vets stay current with evidence-based knowledge

The point-of-care clinical support tool, VETbytes, has added to the veterinary resource by introducing a ‘latest updates’ feed to its first app for emergency and critical care (ECC).

Launched in July in partnership with the BSAVA, VETbytes has enhanced its ability to make relevant research accessible to the end user by implementing a ‘latest updates’ evidence feed to its emergency and critical care (ECC) app.

Vets treating small animals can now access condensed summaries of the most recently published papers relevant to ECC, enabling them to keep up to date with the evidence without having to spend hours reading.

“This new feature will allow users to access real-time updates to the app so they can be assured they are following the most up-to-date clinical guidance,” said Zoë Coker and Bronwen Eastwood, co-founders of VETbytes.

The British Small Animal Veterinary Association (BSAVA), the founding partner of VETbytes, welcomes the development to the ECC app for its members: “The latest addition to the app advances our joint goal with VETbytes, to provide the latest practical, accessible, evidence-based resources for the small animal veterinary community.” said BSAVA President Professor Ian Ramsey.

The VETbytes app is available to BSAVA members with discounted subscription fees and free access is offered to veterinary students.

To view the ‘latest updates’ feed, click here.

The ECC app, available from VETbytes, currently covers more than 100 topics and includes other features such as drug (and CRI) calculators, a quick reference section and links to hundreds of source abstracts, as well as CPD accreditation for reflective learning through usage of the app.

VETbytes is available at the point of care on mobile, iPad or desktop. To start a free trial or subscribe to the VETbytes app, visit www.vetbytes.co.uk.

Fecal microbiota transplantation in parvovirus puppies

We’ve noticed an increase in parvovirus cases recently so we thought we’d share a few snippets from the treatment section of our parvovirus page. To see the full condition, subscribe or sign up for a free trial today.

Did you know?

  • In a recent study, parvovirus-infected puppies that received faecal microbiota transplantation (FMT) in addition to standard therapy showed a faster resolution of diarrhoea compared to dogs that only received standard therapy
  • 61% of cases receiving FMT showed resolution of diarrhoea within 48 hours compared to only 5% without

Method

  • 10 g of healthy donor faeces diluted in 10 ml 0.9% NaCl and introduced anally to the proximal rectum via a urinary catheter
  • Maintain in lateral recumbency for 2 minutes with pelvis raised 45% from the surface
  • Perform within 6–12 hrs of admission and repeat q48h until resolution of diarrhoea, or up to five doses

Don’t forget environmental control

  • Parvovirus can survive in the environment for up to 1 year and is very difficult to kill
  • Clean the area thoroughly first as the presence of organic matter, e.g. faeces or blood, can greatly impact the efficacy of disinfectants
  • Disinfect the environment with sodium hypochlorite (bleach)
    0.75% solution for 1 minute contact time or
    0.37% solution with 15 minute contact time
  • Steam cleaning for surfaces that do not tolerate bleach
  • Careful disposal of faeces

Xylitol poisoning in dogs in less than a minute with VETbytes

Would you know how to handle a case of xylitol toxicity? Get straight to the point of care with VETbytes’ treatment action plan. Read the ‘Key Points’ checklist in under a minute before the client arrives and know that you are up-to-date and ready for action!

Xylitol poisoning in dogs

  • Ingestion can cause hypoglycaemia, hepatic failure or both
  • Dogs that ingest > 0.05–0.1 g/kg are at risk for developing hypoglycaemia
    This usually occurs 30–60 minutes after ingestion
  • Dogs that ingest > 0.5 g/kg are at risk for developing hepatotoxicosis and acute hepatic failure. This usually occurs 1–3 days after ingestion
  • Can estimate that 1 cup of xylitol contains 190g and 1 piece of gum contains 0.3-1g of xylitol
  • Emesis is indicated unless the animal is showing signs of hypoglycaemia or has ingested 100% xylitol products more than 30 minutes prior to presentation as clinical signs may develop during decontamination, risking aspiration
  • Charcoal is NOT recommended as xylitol is readily absorbed from the gastrointestinal tract and binds poorly to charcoal
  • Administer dextrose to hypoglycaemic patients at a dose of 0.25–0.5 g/kg 50% dextrose i/v over 10 minutes (0.5–1 ml/kg 50% dextrose)
  • Hepatoprotectants are indicated in patients that have ingested hepatotoxic doses, e.g. SAMe, Silybin or N-acetylcysteine. There is however no strong clinical evidence to prove their efficacy
  • Additional treatments may include management of coagulation defects and gastroprotectants although evidence is scarce that hepatic disease is a direct cause of gastroduodenal ulceration and erosion
Don’t be caught out!
  • Dogs may present with acute hepatic failure without having shown initial signs of hypoglycaemia
  • Asymptomatic dogs with known ingestion of xylitol should be hospitalised for at least 72 hours in case of delayed-onset hypoglycaemia which may be seen when gum is ingested, or in case of development of hepatic failure without hypoglycaemia
Prognosis is good for dogs that develop uncomplicated hypoglycaemia but poor to guarded for those that develop hepatic failure.
