Kangaroo Mother Care: 25 Years after

UNLABELLEDnThe components of the Kangaroo Mother Care (KMC) intervention, their rational bases, and their current uses in low-, middle-, and high-income countries are described. KMC was started in 1978 in Bogotá (Colombia) in response to overcrowding and insufficient resources in neonatal intensive care units associated with high morbidity and mortality among low-birthweight infants. The intervention consists of continuous skin-to-skin contact between the mother and the infant, exclusive breastfeeding, and early home discharge in the kangaroo position. In studies of the physiological effects of KMC, the results for most variables were within clinically acceptable ranges or the same as those for premature infants under other forms of care. Body temperature and weight gain are significantly increased, and a meta-analysis showed that the kangaroo position increases the uptake and duration of breastfeeding. Investigations of the behavioral effects of KMC show rapid quiescence. The psychosocial effects of KMC include reduced stress, enhancement of mother-infant bonding, and positive effects on the family environment and the infants cognitive development.nnnCONCLUSIONnPast and current research has clarified some of the rational bases of KMC and has provided evidence for its effectiveness and safety, although more research is needed to clearly define the effectiveness of the various components of the intervention in different settings and for different therapeutic goals.

Relief of postoperative pain with jaw relaxation, music and their combination

The aim of this randomized controlled trial was to determine the effect of jaw relaxation, music and the combination of relaxation and music on postoperative pain after major abdominal surgery during ambulation and rest on postoperative days 1 and 2. Opioid medication provided for pain, following abdominal surgery, does not always give sufficient relief and can cause undesired side effects. Thus, additional interventions such as music and relaxation may provide more complete relief. Previous studies have found mixed results due to small sample sizes and other methodological problems. In a rigorous experimental design, 500 subjects aged 18-70 in five Midwestern hospitals were randomly assigned by minimization to a relaxation, music, relaxation plus music, or control group. Interventions were taught preoperatively and tested postoperatively. The same amount of time was spent with subjects in the control group. Pain was measured with the visual analogue sensation and distress of pain scales. Demographic and surgical variables, and milligrams of parenteral or oral opioids in effect at the time of testing were not significantly different between the groups, nor did they correlate with pain scores. Controlling for pretest sensation and distress, orthogonal a priori contrasts and multivariate analysis of covariance indicated that the three treatment groups had significantly less pain than the controls, (P = 0.028-0.000) which was confirmed by the univariate analysis of covariance (P = 0.018-0.000). Post hoc multivariate analysis revealed that the combination group had significantly less sensation and distress of pain than the control group on all post-tests (P = 0.035-0.000), and the relaxation and music groups had significantly less on all tests (P = 0.022-0.000) except after ambulation. At post ambulation those using relaxation did not have significantly less pain than the controls on both days and those using music did not on day 1, although there were some univariate effects. A corresponding significant decrease in mastery of the interventions from pre to post ambulation suggests the need for reminders to focus on the intervention during this increased activity. Physicians and nurses preparing patients for surgery and caring for them afterward, should encourage patients to use relaxation and music as adjuvants to medication for postoperative pain.

Towards universal Kangaroo Mother Care: Recommendations and report from the First European conference and Seventh International Workshop on Kangaroo Mother Care

The hallmark of Kangaroo Mother Care (KMC) is the kangaroo position: the infant is cared for skin‐to‐skin vertically between the mother’s breasts and below her clothes, 24u2003h/day, with father/substitute(s) participating as KMC providers. Intermittent KMC (for short periods once or a few times per day, for a variable number of days) is commonly employed in high‐tech neonatal intensive care units. These two modalities should be regarded as a progressive adaptation of the mother‐infant dyad, ideally towards continuous KMC, starting gradually and progressively with intermittent KMC. The other components in KMC are exclusive breastfeeding (ideally) and early discharge in kangaroo position with strict follow‐up. Current evidence allows the following general statements about KMC in affluent and low‐income settings: KMC enhances bonding and attachment; reduces maternal postpartum depression symptoms; enhances infant physiologic stability and reduces pain, increases parental sensitivity to infant cues; contributes to the establishment and longer duration of breastfeeding and has positive effects on infant development and infant/parent interaction. Therefore, intrapartum and postnatal care in all types of settings should adhere to a paradigm of nonseparation of infants and their mothers/families. Preterm/low‐birth‐weight infants should be regarded as extero‐gestational foetuses needing skin‐to‐skin contact to promote maturation.

Relaxation and music to reduce postsurgical pain

AIMSnWe investigated the effects of relaxation, music, and the combination of relaxation and music on postoperative pain, across and between two days and two activities (ambulation and rest) and across ambulation each day. This secondary analysis of a randomized controlled trial was conducted from 1995 to 1997.nnnBACKGROUNDnAfter surgery, patients do not always receive sufficient relief from opioids and may have undesired side-effects. More complete relief (10-30%) was found recently with adjuvant interventions of relaxation, music, and their combination. Comparison of effects between days and treatments have not been examined longitudinally.nnnMETHODSnWith a repeated measures design, abdominal surgery patients (n = 468) in five US hospitals were assigned randomly to one of four groups; relaxation, music, their combination, and control. With institutional approval and written informed consent, subjects were interviewed and taught interventions preoperatively. Postoperative testing was at ambulation and rest on days 1 and 2 using visual analogue (VAS) sensation and distress of pain scales.nnnRESULTSnMultivariate analysis indicated that although pain decreased by day 2, interventions were not different between days and activities. They were effective for pain across ambulation on each day, across ambulation and across rest over both days (all P < 0.001), and had similar effects by day and by activity.nnnCONCLUSIONnNurses can safely recommend any of these interventions for pain on both postoperative days and at both ambulation and rest.

State of the art and recommendations. Kangaroo mother care: application in a high-tech environment.

Since Kangaroo Mother Care (KMC) was developed in Colombia in the 1970s, two trends in clinical application emerged. In low income settings, the original KMC model is implemented. This consists of continuous (24u2003h/day, 7u2003days/week) and prolonged mother/parent–infant skin‐to‐skin contact; early discharge with the infant in the kangaroo position; (ideally) exclusive breastfeeding; and, adequate follow‐up. In affluent settings, intermittent KMC with sessions of one or a few hours skin‐to‐skin contact for a limited period is common. As a result of the increasing evidence of the benefits of KMC for both infants and families in all intensive care settings, KMC in a high‐tech environment was chosen as the topic for the first European Conference on KMC, and the clinical implementation of the KMC model in all types of settings was discussed at the 7th International Workshop on KMC. Kangaroo Mother Care protocols in high‐tech Neonatal Intensive Care Units (NICU) should specify criteria for initiation, kangaroo position, transfer to/from KMC, transport in kangaroo position, kangaroo nutrition, parents’ role, modification of the NICU environment, performance of care in KMC, and KMC in case of infant instability.

Randomized Controlled Trial of Very Early Mother–Infant Skin-to-Skin Contact and Breastfeeding Status

This study was done to evaluate effects of maternal-infant skin-to-skin contact during the first 2 hours postbirth compared to standard care (holding the infant swaddled in blankets) on breastfeeding outcomes through 1 month follow-up. Healthy primiparous mother-infant dyads were randomly assigned by computerized minimization to skin-to-skin contact (n = 10) or standard care (n = 10). The Infant Breastfeeding Assessment Tool was used to measure success of first breastfeeding and time to effective breastfeeding (time of the first of three consecutive scores of 10-12). Intervention dyads experienced a mean of 1.66 hours of skin-to-skin contact. These infants, compared to swaddled infants, had higher mean sucking competency during the first breastfeeding (8.7 +/- 2.1 vs 6.3 +/- 2.6; P < .02) and achieved effective breastfeeding sooner (935 +/- 721 minutes vs 1737 +/- 1001; P < .04). No significant differences were found in number of breastfeeding problems encountered during follow-up (30.9 +/- 5.51 vs 32.7 +/- 5.84; P < .25) or in breastfeeding exclusivity (1.50 +/- 1.1 vs 2.10 +/- 2.2; P < .45). Sucking competency was also related to maternal nipple protractility (r = .48; P < .03). Very early skin-to-skin contact enhanced breastfeeding success during the early postpartum period. No significant differences were found at 1 month.

Randomized controlled trial of kangaroo care: cardiorespiratory and thermal effects on healthy preterm infants.

Purpose: To determine the safety and effects on healthy preterm infants of three continuous hours of kangaroo care (KC) compared to standard NICU care by measuring cardiorespiratory and thermal responses. Design: Randomized controlled trial—pretest-test-posttest control group design. Sample: Twenty-four healthy preterm infants (33–35 weeks gestation at birth) nearing discharge. Eleven of the infants received KC; 13 received standard NICU care. Main Outcome Variables: Heart rate, respiratory rate, oxygen saturation, and abdominal skin temperature were manually recorded every minute. Apnea, bradycardia, periodic breathing, and regular breathing were captured continuously on a pneumocardiogram printout. Three consecutive interfeeding intervals (three hours each) on one day constituted the pretest, test, and posttest periods. Results: Mean cardiorespiratory and temperature outcomes remained within clinically acceptable ranges during KC. Apnea, bradycardia, and periodic breathing were absent during KC. Regular breathing increased for infants receiving KC compared to infants receiving standard NICU care.

Effect of Nonnutritive Sucking On Behavioral State In Preterm Infants Before Feeding

To describe the effect of nonnutritive sucking (NNS) on behavioral state (BSt) in preterm infants before feedings 24 preterm infants were randomly assigned and studied before each of their first 16 bottle feedings. Twelve received NNS by pacifier for 5 minutes; 12 did not receive a pacifier. BSt was measured with a 12-category scale for 30 seconds before the 5-minute period (BSt1) and for 30 seconds after (BSt2). Sleep states decreased for both groups. BSts considered more optimal for feeding increased more during NNS (86 vs. 46). Restless states were three times less frequent after NNS (23 vs. 68). Differences between groups were nonsignificant at BSt1, but were significant at BSt2, p < .001. In the absence of self-regulatory feeding policies based on early hunger cues, NNS for 5 minutes prefeeding is simple, brief, and suitable for implementation in busy neonatal intensive care units. Nonnutritive sucking was an effective modulator of behavioral state for this sample.

Sensation and Distress of Pain Scales: reliability, validity, and sensitivity.

Psychometric properties of the Sensation and Distress of Pain Visual Analogue Scales (VAS) are compared to dual numerical rating scales (NRS) with data from a randomized controlled trial of postoperative patients. On postoperative days 1 and 2, 15-minute test-retest reliability was .73 to .82 for the VAS and slightly lower for the NRS, r = .72 to .78, while convergent validity of the scales ranged from r = .90 to .92; construct validity of sensation and distress ranged from r = .72 to .85; and discriminant validity was lower, r - .65 to .78. Both instruments were significantly associated with pain reduction following treatment, p < .05 to .01. The VAS scores were significantly lower, p < .01 to .001, and more evenly distributed than NRS scores. It is recommended that the VAS be used in research to produce continuous scores that are more suited to parametric analysis.

Kangaroo care and breastfeeding of mother-preterm infant dyads 0-18 months: a randomized, controlled trial.

Purpose: To determine the effects of kangaroo care (KC) (skin-to-skin contact) on breastfeeding status in mother–preterm infant dyads from postpartum through 18 months. Design: Randomized, controlled trial. The control group received standard nursery care; in the intervention group, unlimited KC was encouraged. Sample: A subsample of 66 mothers and their preterm infants (32–36 completed weeks gestation, 1,300–3,000 g, 5 minute Apgar ≥6) who intended to breastfeed. Main Outcome Variables: Breastfeeding status at hospital discharge and at 1.5, 3, 6, 12, and 18 months as measured by the Index of Breastfeeding Status. Results: KC dyads, compared to control dyads, breastfed significantly longer (5.08 months vs 2.05 months), p = .003. KC dyads also breastfed more exclusively at each measurement, p = .047. More KC dyads than control dyads breastfed at full exclusivity (100 percent breast milk, index of breastfeeding status levels 1 or 2) at discharge and at 1.5, 3, and 6 months. Mean KC contact per day was 4.47 hours.
