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

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
