Feline blood donation via cephalic intravenous catheter: A novel method
1Clinical Science and Services, Royal Veterinary College, Hatfield, UK.
Insights
Feline blood donation via intravenous catheter is a viable alternative to jugular donation, requiring less restraint and sedation. This method showed comparable results in packed red blood cell haemolysis, indicating its effectiveness for feline donors.
Area of Science:
- Veterinary Medicine
- Animal Science
- Hematology
Background:
- Feline blood donation traditionally requires heavy sedation or a highly compliant cat.
- Intravenous catheter donation offers a less restrictive alternative, potentially reducing donor stress.
Purpose of the Study:
- To evaluate the feasibility and outcomes of feline blood donation using intravenous catheters.
- To compare the percentage of haemolysis in packed red blood cells obtained via catheter versus jugular donation.
Main Methods:
- An observational study was conducted on feline blood donors between February and June 2023.
- Blood donation via cephalic catheter was attempted in cats anticipated to resist jugular donation.
- Percentage haemolysis was calculated for packed red blood cells from both catheter and jugular donations.
Main Results:
- Catheter donation was successfully used in 13 cats, with minimal sedation required for most.
- Mean haemolysis percentage for catheter donations (0.21%) was not significantly different from jugular donations (0.20%).
- The method proved successful in cats with calm temperaments.
Conclusions:
- Intravenous catheter donation is a successful method for feline blood collection.
- This technique can be an alternative when jugular donation is challenging, though not universally applicable.
Background:
Feline jugular blood donation requires heavy sedation or a very compliant cat. Donation using an intravenous catheter requires less restraint and potentially decreases stress.
Methods:
This was an observational study of feline blood donors at a veterinary hospital between February and June 2023. Blood donation through a standard cephalic catheter was attempted in cats that were anticipated not to tolerate jugular donation. The percentage haemolysis of the donated packed red blood cells was then calculated for catheter and jugular donations.
Results:
Forty-six donations were performed over the study period. The catheter donation method was used successfully in 13 cats, of which eight were not sedated and five were mildly sedated with butorphanol and/or gabapentin. In four cats, a combination of jugular and catheter donation methods was used (all sedated). In 29 cats, the jugular method alone was used; four of these cats were sedated. The mean percentage haemolysis of the packed red blood cells from 11 catheter donations and 11 jugular donations was 0.21% (standard deviation: 0.11, range: 0.10-0.43%) and 0.20% (standard deviation: 0.14, range: 0.01-0.54%), respectively. These values were not significantly different.
Limitation:
Cats had been selected for a calm temperament.
Conclusion:
Although not possible in all cats, intravenous catheter donation can be a successful method for blood donation.
