Objetive: To determine healthy neonates birthweight born from healthy Lima pregnant women without obstetrical complications. Materials and Methods: A retrospective, analytic and transversal study was conducted. Maternal and perinatal data was retrieved from the Department of Obstetrics/Gynecology and Pediatrics Database at Hospital Nacional Docente Madre-Niño San Bartolome from January 1, 1991 through December 31, 1999. Healthy singleton pregnant women 20 to 30 years old, BMI 20 to 25 kg/mt2 , without obstetrical complications, with a difference ± 2 weeks between last menstrual period and gestational age by physical assessment of the healthy living neonate were selected. Results: Birthweights of 5,443 healthy neonates in Lima [50th percentile [10th percentile- 90th percentile]) at 35, 36, 37, 38, 39, 40, 41, and 42 gestational weeks were 2640 (2346-3356), 2850 (2430- 3344), 3100 (2688-...

Objetive: To establish values for neonatal ponderal index (PI) in a group of healthy fetuses born from healthy singleton pregnant women at Lima, Peru. Materials and Methods: A retrospective, analytic and transversal study was conducted. Maternal and perinatal data from January 1, 1991 through December 31,1999 was retrieved from the Department of Obstetrics/Gynecology and Pediatrics Database at Hospital Nacional Docente Madre-Niño “San Bartolome”. Healthy singleton pregnant women between 20 and 30 years old, BMI between 20 and 25 kg/m2 , without obstetrical complications, with a difference ± 2 weeks between last menstrual period and gestational age by physical assessment of a live-healthy neonate were selected. PI was defined as birthweight in grams x 100/ [crown-heel length]3 . Results: The PI [50th percentile (10th percentile- 90th percentile)] in 5,443 Lima healthy neonates at 35...

OBJECTIVE: To establish the values of head circumference (PC) of a group of healthy newborns Lima children of women who had healthy singleton pregnancies. DESIGN: Retrospective, analytical and transversal study. MATERIALS AND METHODS: Based on maternal and perinatal data from the Department of Obstetrics and Pediatrics National Teaching Hospital Mother-Child "San Bartolome" between January 1, 1991 and December 31, 1999 (SIP) was reviewed. Singleton pregnancies of women between 20 and 30 years, with BMI between 20 and 25 km / m2 was selected healthy without obstetric complications, with difference ± 2 weeks between EG FUR and physical examination of the living and healthy newborn. RESULTS: The sound in Lima (50th percentile (10th percentile-90th percentile)) 5443 head circumference of newborns (NB) at weeks 36,36,37,38,39,40,41 and 42 were 33 (31-35 ), 33 (31-35), 34 (32 to 35.5), 34 (32...

OBJECTIVE. To ascertain the maternal and fetal variables that predict fetopelvic disproportion (FPD). SETTING. Hospital Nacional Docente Madre-Niño San Bartolome, Lima, Peru. DESIGN. Clinical retrospective study. Participants. Pregnant women with labor second stage arrest and birth by cesarean section. INTERVENTIONS. Retrospective study of our Perinatal Data Base from January 1, 1991 to December 31, 1999. Fetopelvic disproportion (FPD) was defined as labor arrest during 2 hours in nulliparous and 1 hour in multiparous women at the second stage of labor and delivery of the baby was by cesarean section. Logistic regression (LR) and ROC analysis were performed. MAIN OUTCOME MEASURES. FPD prevalence and associated conditions. RESULTS. The prevalence of FPD was 1,28% (583/45,386). As compared with women without FPD, women with FPD significantly presented lower stature –less than 160 cm–,...

Objective: To ascertain that social and emotional deprivation of the mother is associated with fetal growth restriction, fetal death, preterm birth and congenital defects. Materials and Methods: We retrieved the maternal and perinatal outcome from the Informatic Perinatal System of all pregnancies with antenatal care whose delivery occurred between January 1, 1992 and December 31, 2001. Three groups of patients with social and emotional deprivation were included: 1) single women (n=1285), 2) teenage women with absent prenatal care (APC), (n=2131), and 3) primigravid with stature lower than 160 cm (n=35722). Maternal and perinatal outcome were compared with: 1) women living with sexual partner (n=5550), 2) teenage women with prenatal care (n=7644), and 3) primigravids taller than 159 cm (n=5264). Odds ratio and 95% confidence interval (CI) were calculated. Results: Single women presented ...

OBJECTIVES: To determine pregnancy complicated by arterial hypertension pathogenic factors. DESIGN: Retrospective clinical study. SETTING: Hospital Nacional Docente Madre-Niño San Bartolome, Lima.PARTICIPANTS: Women with pregnancies complicated by arterial hypertension. INTERVENTIONS: The hospital’s perinatal information technology system was reviewed from January 1991 through December 2006 in order to determine the prevalence of pregnancies complicated by arterial hypertension, to establish associated factors and describe its natural history. MAIN OUTCOME MEASURES: Pregnancy arterial hypertension prevalence and conditioning factors. RESULTS: Pregnancy arterial hypertension prevalence was 8,6% (8 506/98 956). Preeclampsia and eclampsia represented 95% (8 085/8 506) of these cases, preeclampsia prevalence was 8,5% and eclampsia, 0,11%. Preeclampsia and eclampsia conditioning factors we...
