ticllts during pregnarlcy, we are reminded by and colleag~~es’ that perhaps such rigid control ncc-ess;i~~) loi- a successful perinatal outcome.

Liberal and prolonged hospitalizatiotls in most cases may not be cost effective if one looks at the cc>mplications, some of cvhich may be monitored and a\c~ted on an outpatient basis. This is especially trtle 1, l~cn one considers that intensive monitoring, such a, estriol and the nonstress test, was not essential ;untl WI, not part of their protocol.

rigid control will prevent many complications and this in turn may hopefully lead to an improved quality of babies. Perhaps one ought not to-judge success by such a crude measurement as the mortality rate bul rathel by the quality of the survivors. I invite comments from authors as well as from other concerned investigators regarding the trencl in IMJIagement of pregnant diabetic patients as it concerns the degree of blood sugar control and the intcnsit); of fetal surveillance so that we may explore the limits and direction in which we are moving. 0b.ttrtric.t

Reply to Dr. Semchyshyn To the Editors:
Dr. Semchyshyn correctly points out that extensive hospitalization was an important factor in ac-hieving successful pregnancy for our patients. We must emphasize that our liberal use of hospitalization was in part for the purpose of improving glucose control according to the prevailing national trend in this direcin well-selected and high11 tion. Unquestionably. “. motivated patients .” ambulatory management can be successful. The patient population at Parkland Memorial Hospital is primarily indigent and we find that in-hospital management most dependably provides our patients with the care they need. Dr. Semchyshyn suggests use of antepartum electronic and hormonal tests of fetal-placental condition as a replacement for prolonged hospitalization. He also suggests that these tests may be useful in preventing preterm delivery and the associated neonatal complications of prematurity. We agree that certain neonatal complications are the result of preterm delivery. It is impossible for 11s to address directly the role of’ stress tests and estriol measurements in preventing preterm delivery since we did not use these methods of fetal surveillance. In a report by Gabbe and associates,’ antepartum testing permitted SSs of women to be delivered beyond 38 lveeks of gestation. However, as
