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...

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-...

Obejetive: To identify the etiopathogenic factors associated to both fetal and neonatal deaths in Lima, Peru. Materials and methods: Retrospective study of all the cases of fetal death over 20 weeks gestation and neonatal death before 28 days of life that underwent autopsy and histopathologic study, in order to identify the cause of perinatal death. Settings: Hospital San Bartolomé in Lima, between January 1, 1996 and December 31, 2000. Results: The prevalence of fetal death was 1,68% (508/30125) and neonatal death 1,44% (434/30125). All fetal deaths and 58,8% (255/434) of the neonatal deaths underwent autopsy. Among 508 fetal deaths, 92 (18%) presented signs of autolysis that did not allow appropiate identification of the etiopathogenic process. Fetal death was associated to prematurity (60,5%), nutricional/vascular defect (78,1%), social privation (60,8%), congenital anomaly (14,6%) a...

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–,...
