Obstetric outcome among naturally and IVF conceived twins

Abstract
Pregnancy and delivery are generally perceived to be more hazardous among twins compared to singletons. Assisted conception techniques have increased the number of twins, but the effect on obstetric management and outcome is not well known. During 1990-1993 there were 254 twin pregnancies of 5? 16 weeks gestation in Iceland, of which 52 (20.5%) were after IVF; — a twin rate of 1:73 deliveries. The natural rate was 1:90. IVF women were on average 3 years older but of equal height and smoking habits as the natural mothers. Mean gestational age was 36 ±3.68 (SD) weeks for both IVF and natural twins. In 61.9% labour commenced spontaneously after natural conception, compared to 51.9% after IVF (N.S.) and 64.4% of natural and 58.8% of IVF twins were delivered normally (N.S.). Caesarean section rates were almost equal, but there were twice as many forceps and ventouse deliveries of IVF babies (p<0.02). There appeared to be a minor tendency for more frequent elective Cesarean section in IVF pregnancies, but emergency section was more prevalent among those who conceived naturally. IVF twins were on average 64g lighter (mean birthweight 2552g) than natural twins (mean birthweight 2616g), which was unaffected by smoking habits and gestional length. The sex ratio was higher among IVF twins. IVF twins were more often admitted to neonatal intensive care, but remained there a shorter time. This suggests a lower threshold for admission of twins conceived following IVF treatment. Perinatal mortality was not different among natural compared to IVF twins; 20/1000 by conventional criteria. However when total perinatal wastage was calculated, the figure was 46.5/1000, suggesting excess deaths early in pregnancy and beyond the first week of life in twin pregnancies in general.
Tvíburameðgöngur og -fæðingar eru almennt taldar áhættumeiri en einburafæðingar. Með tilkomu tæknifrjóvgunar hefur tvíburafæðingum fjölgað en lítið er vitað um áhrif þess á meðferð og útkomu tvíburafæðinga. Á tímabilinu 1990-1993 voru 254 tvíburameðgöngur á Íslandi, þar sem meðgöngulengd var 16 vikur eða meira. Af þeim voru 52 (20,5%) eftir glasafrjóvgun. Tíðni tvíburafæðinga var í heild 1:73 en meðal eðlilega getinna tvíbura var hún 1:90. Konur sem fóru í glasafrjóvgun voru að meðaltali þremur árum eldri en þær sem urðu eðlilega þungaðar. Ekki var munur á líkamshæð eða reykingavenjum. Meðalmeðgöngulengd var 36 ± 3,68 (SD) vikur hjá báðum hópunum. Fæðing hófst eðlilega hjá 61,9% kvenna með náttúrulega þungun og hjá 51,9% kvenna í glasakomna hópnum (N.S.). Hjá 64,4% kvenna með náttúrulega þungun og 58,8% kvenna í glasahópnum varð eðlileg fæðing. Fjöldi valinna og bráðra keisaraskurða var svipaður þó tilhneiging hafi sést til tíðari fyrirfram ákveðinna keisaraskurða í glasakomna hópnum. Inngrip í fæðingu með töng eða sogklukku voru algengari hjá glasafrjóvgaða hópnum (p< 0,02). Glasakomnu tvíburarnir voru að meðaltali 64g léttari (meðalþyngd 2552g) en náttúrulega getnu tvíburarnir (meðalþyngd 2616g) sem var óháð reykingum og meðgöngulengd. Kynhlutfall var hærra hjá glasakomnum tvíburum. Glasakomnir tvíburar voru oftar lagðir inn á vökudeild en dvöldu þar skemur. Burðarmálsdauði var svipaður í báðum hópunum eða 20/1000 samkvæmt hefðbundinni skilgreiningu. Í öllum meginatriðum var meðferð og útkoma í tvíburameðgöngum eftir glasafrjóvgun ekki frábrugðin því sem er eftir náttúrulega þungun.
