Twin gestations and prophylactic hospitalization.

The study evaluates the benefit of elective hospitalization in preventing premature deliveries of twin gestations. Three groups of women with twin gestations, having no other complications of pregnancy which could cause premature delivery, were evaluated. The study group was comprised of 43 women who were electively hospitalized between 30-32 and 36 weeks of gestation. Control group 1 was comprised of 55 women who were not hospitalized but were instructed to rest at home. Control group 2 was comprised of 53 women who were not hospitalized and were not instructed to rest at home. Our results showed that elective hospitalization did not significantly affect the gestational duration or the prematurity rate. However the mean birthweight difference between the study group and the two control groups were 143 +/- 83 g and 205 +/- 84 g, respectively. This result was more significant in multiparous women. The slight increase in birthweight of the hospitalized women compared to the controls, does not seem to justify the cost of hospitalization.
