Maternal dystocia
  • Prolonged gestation.
  • Primary uterine inertia - inability of uterus to contract sufficiently (some breed predisposition, eg Boxer Boxer ).
  • Secondary uterine inertia, uterine muscles become exhausted after prolonged contraction (obstructing fetus, large litter, some breed predisposition, eg brachycephalics).
  • Unmanageable obstruction of birth canal, eg pelvic fracture.
  • Uterine anomaly, eg torsion, inguinal herniation of gravid uterus.
Fetal dystocia
  • Relative or absolute fetal oversize.
  • Irreduceable malpresentation.
  • Fetal death/putrefaction/mummification.
  • Signs of fetal distress in prolonged or difficult parturition.
  • Fetal deformity, eg fetal monster.
ElectiveCesarean
  • History of previous dystocia.
  • Predictable dystocia associated with breed type especially brachycephalics.

Advantages

  • Increased chance of live pups following rapid removal of viable fetuses.

Disadvantages

  • Anesthetic depression of fetus.
  • Care required to prevent fetal hypoxia.
