material and size would be suitable for the following tissues?

linea alba

A

MonoPlus(PDS) – (long term support) 3 metric or for a lively dog consider 3.5metric

material and size would be suitable for the following tissues?

subcutaneus tissue

A

Monosyn (monocryl) size 3 metric

(in brackets is Ethicon equivalent)

53
Q

A lively 25 kg labrador bitch is to have an ovariohysterectomy, what suture
material and size would be suitable for the following tissues?

subcuticular tissue?

A

Monosyn (monocryl) size 3 metric

(in brackets is Ethicon equivalent)

54
Q

A lively 25 kg labrador bitch is to have an ovariohysterectomy, what suture
material and size would be suitable for the following tissues?

skin?

A

Dafilon(Ethilon) Non-absorbable would be the choice but Supramid or Optilene also suitable,this choice ensures your patient comes back for a check-up to have the sutures removed.
