1737 J. Gibson in Med. Ess. & Observ. (ed. 2) I. xiii. 183 I..do appeal to those who are conversant in Embryotomy, whether they do not for most part find all, as well human as brute Fœtuses..to have their Mouths more or less open.

2. Obstetrics and Veterinary Medicine. Perforation of the head of a fetus (cf. craniotomy n. at cranio- comb. form 2) or dismembering of a fetus in order to facilitate its removal from the mother, esp. in cases of obstructed labour or fetal death; an instance of this.

1765 T. H. Croker et al. Compl. Dict. Arts & Sci. II Embryotomy, the cutting a fœtus to pieces whilst in the womb, practised in cases of necessity, when there is no other way of saving the mother.

1769 R. W. Johnson New Syst. Midwifery iii. ix. 304 If the pelvis is expanded so much on one side of the straits, as to admit of an introduction of the hand, there is then a probability of effecting the delivery by embryotomy.

1842 Provinc. Med. Jrnl. 23 Apr. 52/1 Having a slightly contracted pelvis, and generally very large children, she has never been able to give birth to a fœtus at the full period of utero-gestation, without submitting to the operation of embryotomy.

1864 R. Jennings Cattle & their Dis. 250 When this [turning of the fetus] cannot be accomplished, the only resort is embryotomy,..which operation can only be safely performed by the qualified veterinary surgeon.

1913 Lancet 1 Mar. 606/2 All writers agree that the embryotomies for this condition [sc. contraction ring] have been extraordinarily difficult.

1992 Vancouver Sun (Nexis) 3 Oct. d10 Often the single lamb was dead through pressure and had to be removed by embryotomy or a Caesarean operation.

2011 Times (Nexis) 3 Dec. (Features section) 114 One of the baby skeletons found at the Yewden Roman villa in Buckinghamshire shows evidence of embryotomy, the dismemberment of a dead foetus inside the mother to extract it in pieces.

Compounds

General attributive (in sense 2), esp. in the names of obstetrical instruments.

1828 Lancet 5 Apr. 4/2 The latter may be called the embryospastic instruments, the former the embryotomic.

1828 Lancet 17 May 194/1 The smallest aperture through which a full grown fœtus may be abstracted by the embryotomic operations..must be, at least, three inches in its length.

1888 Brit. Med. Jrnl. 18 Aug. 344/2 Such an instrument requires caution and skill in its use, and should be employed chiefly as a substitute for embryotomic implements.
