The difficult first week at home with a premature infant.

The results reported were obtained from the findings of a larger descriptive study that surveyed the support needs of 56 mothers of high-risk premature infants. Forty-eight percent of the mothers found the first week after their infant's discharge home difficult. Data analysis indicated the more premature the infant (birth weight r = 0.29, P = 0.03; gestational age r = 0.34, P = 0.008), and the greater the severity of illness as determined by length of hospital stay (r = -0.27, P = 0.04), the more likely the mother was to have a difficult first postdischarge week. The visit of the community health nurse during that first week was a significant factor in whether the mothers perceived the time as difficult (Fisher's exact test, P = 0.02). It was found, as well, that the community health nurses were less likely to visit mothers of very low-birth-weight infants during that week (Fisher's exact test, P = 0.02). Other variables related to difficulty during the first week were whether the infants had apnea in hospital (r = 0.33, P = 0.01), mothers' need for specific kinds of information such as knowledge about colic (chi 2 = 24.31, df = 12, P = 0.02), and an earlier scheduled visit to a physician for mothers whose infants were of lower birth weight (r = -0.26, P = 0.05), earlier gestational age (r = -0.34, P = 0.009), and had spent longer time in hospital (r = 0.37, P = 0.006).

Caffeine: how much is too much?

Too much caffeine can cause numerous physical and psychological symptoms of poor health. It could negatively affect reproduction and is suspected of causing some cancers. It can affect cardiovascular functioning, and can even produce symptoms similar to those of mental illness. Despite this broad range of known and suspected effects of caffeine, nurses rarely consider caffeine intake in initial nursing assessments of clients. They should.

The information and support needs of mothers of premature infants.

This research was a descriptive study that surveyed the support needs of a nonrandom convenience sample of 56 mothers of high-risk premature infants. The results indicated that these mothers' received information similar to that given to mothers of healthy full-term newborns and information that they wanted on the "colicky" or crying infant, noisy breathing, "spitting up," infant behavior, infant illness, and prematurity was not given to them. Mothers who reported that they needed more information and did not receive it were more anxious and less confident in caring for their infant. The majority of the mothers felt well-supported, although many of the mothers found the infant's first postdischarge week difficult.

Caffeine and its effects on pregnancy and the neonate.

In animal studies, fetal loss, decreased fetal weight and size, and major skeletal defects have been reported when dosages of more than 80 mg/kg of caffeine were used. Human epidemiologic studies that examine the relationship between caffeine use and congenital abnormalities are not conclusive; however, there is some evidence to suggest a caffeine effect upon fetal growth patterns. Because caffeine drinking is so often associated with the use of other drugs such as tobacco, it is difficult to ascertain which drug has the effect on growth, or if it is a combined effect from both drugs. A tripling of the half-life of caffeine in the last two trimesters of pregnancy resulting in much higher caffeine blood levels for both mother and fetus, combined with the neonate's inability to metabolize caffeine, could account for the indications of neonatal caffeine withdrawal observed in the first week after birth.
