Mindful Kangaroo Care: mindfulness intervention for mothers during skin-to-skin care: a randomized control pilot study

Background

Parents of babies admitted to the Newborn Intensive Care Unit (NICU) undergo considerable stress. There is evidence that mindfulness reduces stress in these parents. Kangaroo Care (KC) is practiced in NICUs across the world and is stress-relieving. Whether mindfulness practiced during KC in the NICU reduces parental distress has not yet been studied. The objective was to explore the feasibility and acceptability of teaching and practicing mindfulness during KC for mothers of premature babies. The objective was also to document preliminary outcomes of Mindful Kangaroo Care (MKC) on maternal stress, anxiety, depression, and mindful awareness.

Methods

In this pilot randomized controlled study, mothers of premature babies who were expected to stay in the NICU for at least four weeks were taught two mindfulness exercises to practice during KC and compared to mothers who received standard care with no mindfulness teaching. Mothers filled out stress, anxiety, depression and mindful awareness scales at recruitment and after four weeks. Acceptability and feasibility questionnaires were also completed.

Results

Fifteen mothers per group completed the study. The MKC group demonstrated a significant within-group reduction in anxiety (p = 0.003), depression (p = 0.02) and stress (p = 0.002), and a significant increase in both the curiosity (p = 0.008) and decentering (p = 0.01) scores of the Toronto Mindfulness Scale, all of which had medium to large effect sizes. Only the increases in curiosity and decentering were significant between groups. Fourteen mothers found the intervention acceptable, one neutral.

Conclusion

MKC was acceptable, feasible and led to a reduction in stress, anxiety and depression in mothers who practiced mindfulness exercises during KC.

Policy change for infants born at the "cusp of viability": a Canadian NICU experience

Resuscitation and life-support treatments for infants born at the "cusp of viability" continue to be subject to clinical and ethical debate. Reported positive outcomes for these infants led our Neonatal Program to critically review our historic practice of discouraging resuscitation of infants born at <24 weeks' gestational age. This practice change required a multifaceted, collaborative approach including neonatal, perinatal, and obstetric efforts. An exceptional experience was the formation of a dedicated working group that included invaluable input from parents who had lived the NICU experience. The inclusion of family members in the development of clinical policy was a novel experience for NICU staff, which we feel ultimately resulted in a more ethically sound approach to the care of these infants and their families. In this article, we explore our experience of the process of policy change, which although detailed and transparent was also complex and challenging in development and implementation.

Ototoxic drugs and sensorineural hearing loss following severe neonatal respiratory failure

AIM

To determine relationships between ototoxic drugs and 4-y sensorineural hearing loss (SNHL) in near-term and term survivors of severe neonatal respiratory failure.

METHODS

All 81 survivors of the Canadian arm of the Neonatal Inhaled Nitric Oxide Study (mortality 32, loss to follow-up 9) received loop diuretics, aminoglycosides, and neuromuscular blockers (NMB), and 50 received vancomycin as neonates. Prospective, longitudinal secondary outcome using audiological tests diagnosed late-onset, progressive SNHL in 43 (53%); not flat (sloping) in 29, flat (severe to profound) in 14. Risk for SNHL was determined.

RESULTS

A combination of duration of diuretic use of >14 d and average NMB dose of >0.96 mg/kg/d contributed to SNHL among survivors (odds ratio 5.2; 95% CI 1.6, 16.7). Markers of illness severity did not contribute. Dosage or duration of aminoglycosides use did not relate to SNHL. Cumulative dosages and duration of use of diuretics; NMB; use of vancomycin; and overlap of diuretics with NMB, aminoglycosides, and vancomycin individually linked to SNHL (p<0.001).

CONCLUSION

Overuse of loop diuretics and/or NMB contributes to SNHL after neonatal respiratory failure; markers of illness severity or the appropriate administration of aminoglycosides do not.

Late-onset, progressive sensorineural hearing loss after severe neonatal respiratory failure

OBJECTIVES

To determine the prevalence of sensorineural hearing loss (SNHL) at the age of 4 years among survivors of severe neonatal respiratory failure with and without congenital diaphragmatic hernia and to document the occurrence of late-onset or progressive SNHL among the survivors.

DESIGN

Prospective, longitudinal secondary outcome study.

SETTING

Multicenter Canadian study in 9 tertiary referral centers.

PATIENTS

Eighty-one (89%) of ninety 4-year-old survivors born from 1994 to 1996 of > or =34 weeks gestation at birth with severe neonatal respiratory failure (2 oxygenation indices > or =25 at least 15 minutes apart).

MAIN OUTCOME MEASURES

Repeated audiologic measurements from birth to the age of 4 years with documentation of the entire cohort at 2 and 4 years of age.

RESULTS

Forty-three (53%) of 81 tested 4-year-old survivors had SNHL; 28 (42%) of 66 without congenital diaphragmatic hernia and 15 (100%) of 15 with congenital diaphragmatic hernia. High-frequency SNHL occurred in 65% of the patients. Of the 43 children with SNHL at 4 years, 30 (70%) had loss at 2 years, and 18 (60%) of these 30 had progressive loss between 2 and 4 years of age. For 13 children with SNHL onset after 2 years of age, the loss was less severe with lesser involvement of the lower frequencies.

CONCLUSION

Survivors of severe neonatal respiratory failure frequently develop late-onset SNHL that may be progressive. Urgent investigation is required to enable further understanding and prevention of this problem. Severe neonatal respiratory failure should be an indication for long-term audiologic surveillance.

Prolonged use of pancuronium bromide and sensorineural hearing loss in childhood survivors of congenital diaphragmatic hernia

Sensorineural hearing loss (SNHL) is a significant neurologic morbidity in survivors of neonatal congenital diaphragmatic hernia (CDH), with a reported incidence of up to 60%. In a historical cohort study of 37 neonates with CDH, we investigated the use of pancuronium bromide (PB) and common ototoxic drugs during the neonatal period and their relationship to SNHL in childhood survivors. Survivors with SNHL (n = 23) had significantly higher cumulative dose of PB administered during the neonatal illness than survivors without SNHL (n = 14). The cumulative dose and duration of PB use significantly correlated (r = 0.66-0.81) and independently predicted (adjusted r (2) = 0.42-0.64) the greatest intensity (in decibels) and the widest band (lowest frequency in hertz) loss of SNHL. No differences were identified between survivors with and without SNHL regarding demographic and neonatal characteristics (including oxygenation and ventilation variables and the cumulative dose and duration of therapy with aminoglycosides, vancomycin, and furosemide), although survivors with SNHL had received a modestly higher cumulative dose of ethacrynic acid than survivors without SNHL. Although we show that prolonged administration of PB during the neonatal period is associated with SNHL in childhood survivors of CDH, further multicenter studies are required to investigate the possible etiologies of SNHL in this high-risk population.
