Efeito da posição do prematuro no desmame da ventilação mecânica

Objective: the purpose of this study was to determine the effects of prone positioning on cardiorespiratory stability and weaning outcome of preterm infants during weaning from mechanical ventilation. Methods: from January to December 1999, a sample of 42 preterm infants, with birthweight < 2,000 g, mechanically ventilated in the first week of life, were randomly divided, in the beginning of the weaning process, in two groups according to the position: supine position (n = 21) or prone position (n = 21). Heart rate, respiratory rate, transcutaneous oxygen saturation and ventilatory parameters were recorded every one hour. Length of the weaning process and complications were also assessed. Results: in both groups the mean gestational age was 29 weeks, most of the patients presented very low birthweight and respiratory distress syndrome. The mean length of the weaning process was 2 days. There were no differences between the groups regarding respiratory rate, heart rate and transcutaneous oxygen saturation, however, oxygen desaturation episodes were more frequent in supine position (p = 0.009). Ventilatory parameters decreased faster and reintubation was less frequent in the prone group (4% versus 33%). No adverse effects of prone positioning were observed. Conclusion: these results suggest that prone position is a safe and beneficial procedure during the weaning from mechanical ventilation and may contribute to weaning success in preterm infants.

Plasma suíno e ovo inteiro em rações de leitões sobre desempenho na fase inicial e efeito residual até a terminação

Were used 64 weaned pigs, distributed in eight treatments: ration with skim milk (SM), three rations with crescent levels of swine plasma (SP), three rations with whole egg (WE) and a ration with high inclusion of soybean meal (SB). Daily weight gain (DWG), daily feed intake (DFI) and feed conversion (FC) were evaluated. The animals that consumed ration SB have the mean of DWG higher that other treatments, and inferior FC, from 35 to 48 days of age. The crescent levels of SP promoted linear reduction in DWG, from 21 to 35, and from 35 to 48 days of age, in DFI from 48 to 138 days of age and linear increased in FC from 21 to 35 of age. Considering the weaned phase until finishing, initial rations can be formulated with SP and WE substituted partially the CP of skim milk in 25 and 45%, respectively.

Desmame precoce: Falta de conhecimento ou de acompanhamento?

Objective: To assess the knowledge of women and the instructions received on breastfeeding during pregnancy and after childbirth, and their influence on breastfeeding practice. Method: This study was a longitudinal investigation following 84 pairs of mothers and babies from pregnancy through the sixth month of baby's life. In the first phase of the research, interviews were made with the pregnant women at home and at Basic Health Units to collect information about their intentions and knowledge of breastfeeding. In the second phase of the research, mothers and babies were followed up from the first to sixth month of baby's life to record the difficulties of breastfeeding and reasons for weaning. Results: In the first month, 94.3% (82) of the babies were breastfed, but only 49.4% (43) were breastfed exclusively. At the end of the sixth month of life, 43.7% (38) of the babies had already been weaned. No mother breastfed exclusively her baby within the sixth month. During pregnancy, 60.7% (51) of the mothers had no instructions about breastfeeding and 83.4% (70) of the mothers received instructions on breastfeeding after childbirth. Most mothers (76.2%) knew about the ideal breastfeeding period. Seventy-three (86.9%) mothers believed that breastfeeding was beneficial for the baby, but only 41 (48.8%) of them really breastfed. Only 11 (13.1%) mothers were followed up by the public health system team during lactation. Conclusion: Although most women had been instructed during pregnancy or after childbirth and had knowledge of breastfeeding, early weaning occurred. Advising is important, but the support and follow up of the mothers are of utmost importance for a successful breastfeeding practice.
