Trends in preterm labor.

Preterm birth has been identified by the National Commission to Prevent Infant Mortality (1988) as the primary cause of the increased infant mortality rate in the United States. An analysis of what is currently known about four areas of preterm labor including (1) definition and causes, (2) identification of patients at risk, (3) management techniques, and (4) use of patient education in labor is presented in this paper. Preterm labor is defined as uterine contractions that occur between 20 and 37 weeks' gestation with progressive cervical dilatation or effacement or both. Directions for future research are discussed.

Positioning and skin care of the low-birth-weight neonate.

An analysis of investigations related to positioning and skin care of the low-birth-weight infant, tempered with the authors' clinical experience, is presented. Protocols for positioning the low-birth-weight neonate and care of immature skin are provided. The nursing management plans are theoretically based and provide a foundation for testing the ability of nurses to improve developmental outcomes for this population of infants and reduce the cost of their care. A comprehensive reference list is provided.

Prevalence of illicit drug use among prenatal patients and predictive validity of nurses' judgments.

The purposes of this investigation were to: (1) estimate the prevalence of illicit drug use within the prenatal population of a midwestern suburban ambulatory care center; (2) explore the relationship between nurses' judgments of patient illicit drug use and urine toxicology results; and (3) determine if a difference exists between nurses' judgments of illicit drug use by private physicians' patients (PPP) and nurses' judgments of illicit drug use by resident physicians' patients (RPP). For a 16-week period, all new prenatal patients (N = 189) were included in this study; 78 (41%) were in the RPP group and 111 (59%) were in the PPP group. Urine remaining from routine urinalysis was assayed for seven drugs or drug classes. Fourteen (7.5%) subjects tested positive for illicit drugs, 8 (10.3%) in the RPP group, and 6 (5.4%) in the PPP group (chi 2, P greater than .33). Using a Likert-type scale, nurses rated the likelihood of a positive result of each patient's urine test. Nurses' judgments of patient illicit drug use and positive results were related, r = .28. Nurses were more likely (P less than .0001) to suspect residents' patients of illicit drug use than private physicians' patients.

Pain control after cesarean birth. Efficacy of patient-controlled analgesia vs traditional therapy (IM morphine).

A clinical trial compared the efficacy of a mechanical device to deliver patient-controlled analgesia (PCA) (n = 25) with intramuscularly administered morphine (n = 17) for postcesarean pain management. Hypotheses were: (1) patient-controlled administration of narcotics will be superior (increased satisfaction, reduced pain, decreased sedation, increased ambulation, decreased length of stay), and (2) functional vital capacity will increase post-operatively with PCA. No differences in demographic variables were identified (P = less than or equal to .001). Differences in satisfaction (greater in PCA group, P = less than or equal to .05), ambulation (greater in PCA group, P = less than or equal to .001), amount of medication used (greater in PCA group, P = less than or equal to .001), and sedation level (less in PCA group, P = less than or equal to .05) were identified. No differences in vital capacity were identified. The hypothesis related to the superiority of PCA was accepted, while the association between PCA and increased vital capacity was not supported. The use of mechanical PCA devices provides an effective and safe means of managing postcesarean pain.
