    ABSTRACT: To evaluate whether early oral intake after cesarean delivery has an effect on gastrointestinal outcomes during postpartum recovery. Electronic searches of published studies between 1980 and 2011 were conducted using PubMed, Medline, CINAHL, ClinicalTrials.gov, and Airiti databases. Randomized controlled trials (RCTs) and nonrandomized trials were included. Data were extracted in a systematic manner and the quality of each study was appraised independently by two reviewers. Meta-analyses were conducted only for RCTs using the RevMan5. Seventeen studies met eligible criteria and were retrieved, including 14 RCTs and three non-RCTs. The majority of early oral intake was provided within 6-8 hours after cesarean delivery. Early oral intake was significantly related to the return of gastrointestinal functions compared with delayed oral intake (bowel sounds -9.2 hours; passage of flatus -10 hours; bowel evacuation -14.6 hours). Early oral intake did not significantly increase the occurrence of gastrointestinal complications compared with delayed oral intake after cesarean delivery (ileus symptoms 18.7% compared with 18%, odds ratio [OR] 0.98; vomiting 5% compared with 5.5%, OR 0.9; nausea 10.3% compared with 10.3%, OR 1.03; abdominal distention 9.3% compared with 11.6%, OR 0.82; diarrhea 3.4% compared with 5%, OR 0.62). Early oral intake after cesarean delivery improves the return of gastrointestinal function and does not increase the occurrence of gastrointestinal complications. A clinical implication based on the findings of the current evidence is proposed.

    ABSTRACT: Abstract Background: Breastmilk is usually frozen for premature infants when they are unable to feed orally. However, thawed breastmilk may have altered odor and taste from its original form. Few studies have investigated whether premature infants respond differently to fresh and thawed breastmilk. The purpose of this study was to examine the physiological and behavior responses of premature infants alternately fed fresh and thawed breastmilk. Subjects and Methods: An experimental, crossover study using random assignment was conducted. A convenience sample of 18 premature infants less than 37 weeks gestational age at birth with the capability of oral feeding was studied. The premature infants were fed with fresh and thawed breastmilk during two consecutive meals in a random order. Infants' heart rate and oxygen saturation levels were measured baseline and during feeding, as well as observed feeding cues during the feeding period. Results: Premature infants showed significant differences in heart rate when fed thawed, as opposed to fresh, breastmilk. Premature infants demonstrated more stress cues when fed thawed compared with fresh breastmilk (p=0.007). For infants with postmenstrual ages greater than 36 weeks gestation, feeding with thawed breastmilk showed more stress cues and greater effect on heart rate activity compared with fresh breastmilk (p<0.05). Conclusions: Older premature infants demonstrate more stress when fed with thawed breastmilk. Preterm infants should be directly breastfed or fed with nonfrozen breastmilk, when they show stress behaviors in being fed with thawed breastmilk.
