A pilot study to determine if nurses trained in basic neonatal resuscitation would impact the outcome of neonates delivered in Kampala, Uganda.

AIMS AND OBJECTIVES: To determine if a team dedicated to basic neonatal resuscitation in the delivery ward of a teaching hospital would impact the outcome of neonates delivered in Kampala, Uganda. METHODS: A five-member team of nurses, trained in basic neonatal resuscitation attended 1046 deliveries over a thirty-one day pilot period. They were available in the delivery ward twenty-four hours each day. Outcomes studied included the number of stillbirths recorded on the delivery ward, the number of neonates admitted to the special care baby unit (SCBU), the number of babies admitted to SCBU who died and the mortality in the different weight categories. APGAR scores before and after intervention was also compared. Admission diagnoses between the two groups were also compared. Outcome data collected during this pilot period was compared with historic controls from the previous 31 days in the same unit. PATIENTS AND SETTING: A delivery ward, 22,000 deliveries per year. RESULTS: The stillbirth rate and admission rate to the SCBU were unchanged. Basic neonatal resuscitation in this setting decreased the incidence of asphyxia (defined as failure to initiate and sustain breathing or an APGAR score of <7 at 5 min), improved APGARS and a decrease in the mortality of babies weighing more than 2 kg. CONCLUSION: The resuscitation team reduced the incidence of and mortality from asphyxia and improved the outcome of babies greater than 2 kg. This pilot study provides evidence of the beneficial effect of basic neonatal resuscitation in this setting.

Home-based care for orphaned children infected with HIV/AIDS in Uganda.

The primary aim of this paper is to describe an outreach programme from a main state hospital in sub-Saharan Africa, which has been running for three years. This programme is based in Mulago Hospital, Kampala, Uganda and cares for up to 200 children infected with HIV/AIDS in their home. We describe the clinic and how we meet the families and enrol them, the infrastructure of the programme and the personnel involved. Children and their families receive physical, psychological and social care and we describe each aspect of this. The knowledge base about older children with AIDS in Africa is scarce and the secondary aim of this paper is to publish observations that were made while providing care. This includes demographics and the health problems encountered among children living with HIV/AIDS in a resource-poor setting who do not receive antiretroviral medication. Finally, we discuss the strengths and weaknesses of this model of care and the prerequisites to setting up a similar model.

Review of treatment of bronchiolitis related apnoea in two centres.

AIMS: To determine whether the use of negative pressure ventilation (NPV) was associated with a lower rate of endotracheal intubation in infants with recurrent apnoea secondary to acute bronchiolitis. METHODS: Retrospective review of two paediatric intensive care units (PICU) databases and case notes; one PICU offered NPV. RESULTS: Fifty two infants with bronchiolitis related apnoea were admitted to the two PICUs (31 to the NPV centre). There were no significant differences between infants in the two centres in age and weight on admission, gestational age at birth, birth weight, history of apnoea of prematurity or chronic lung disease, days ill before referral, respiratory syncytial virus status, oxygen requirement before support, and numbers retrieved from secondary care centres. Respiratory support was provided to all 31 infants in the NPV centre (23 NPV, 8 PPV), and 19/21 in the non-NPV centre (18 PPV, 1 CPAP); the NPV centre had lower rates of endotracheal intubation rates (8/31 v 18/21), shorter durations of stay (median 2 v 7 days), and less use of sedation (16/31 v 18/21). In the two years after the NPV centre discontinued use of NPV, 14/17 (82%) referred cases were intubated, with a median PICU stay of 7.5 days. CONCLUSIONS: The use of NPV was associated with a reduced rate of endotracheal intubation, and shorter PICU stay. A prospective randomised controlled trial of the use of NPV in the treatment of bronchiolitis related apnoea is warranted.

Classification of child abuse by motive and degree rather than type of injury.

The protection of children may be enhanced if ill treatment is classified by motive and degree rather than by type of injury. Four categories are proposed: A, abuse: premeditated ill treatment undertaken for gain by disturbed, dangerous, and manipulative individuals; B, active ill treatment: impulsively undertaken because of socioeconomic pressures, lack of education, resources, and support, or mental illnesses; C, universal mild ill treatment: behaviour undertaken by all normal caring parents in all societies; and D, neglect: defined here as an unintentional failure to supply the child's needs. Such a classification could clarify the procedures for investigation and protection, and support the creation of a Special Interagency Taskforce on Criminal Abuse (SITCA) for those suspected of abuse (category A).

How to distinguish between neglect and deprivational abuse.

Neglect is a major cause of inadequate childcare in all societies and should be differentiated from abuse. "Neglect" is defined here, as the "neglectful" failure to supply the needs of the child, including emotional needs. It does not include the deliberate and malicious withholding of needs, which is a form of abuse. Neglect has its roots in ignorance of a child's needs and competing priorities; it is passive and usually sustained. The carer is without motive and unaware of the damage being caused. Malnutrition is a prime example of neglect; the stigma associated with the term abuse should never be applied to the poor struggling or uneducated mother whose child, that she loves dearly, becomes malnourished. Education of the mother and society and relief from the vicissitudes of poverty are required to alleviate most neglect of the world's children.

Negative extrathoracic pressure in infants with cystic fibrosis and respiratory failure.

Respiratory support using negative extrathoracic pressure or high-frequency chest wall oscillation was used to treat 3 infants with cystic fibrosis and respiratory failure who had not responded to maximal medical therapy. Beneficial clinical effects were noted in all three cases. Pulmonary function testing was performed in 2 cases, and measures of compliance increased.

Oxygen saturation during the first 24 hours of life.

AIM: To determine normative data for arterial oxygen saturation, measured by pulse oximetry (SpO2), in healthy full term infants throughout their first 24 hours of life. METHODS: Long term recordings of SpO2, pulse waveform, and breathing movements were made on 90 infants. Recordings were analysed for baseline SpO(2), episodes of desaturation (SpO2 </= 80%), apnoeic pauses of >/= four seconds, and periodic apnoea (>/= three apnoeic pauses, each separated by </= 19 breaths). RESULTS: Median baseline SpO(2) was 98. 3% (range 88.7-100). Longitudinal analysis at four hour intervals showed that SpO2 remained stable until 20-24 hours of age, when it became significantly lower (p < 0.03). Episodic desaturations were identified in 23 recordings. Nine prolonged desaturations (SpO2 </= 80% for >/= 20 seconds) were identified in six recordings. Four desaturations fell to </= 60%. Periodic apnoea was identified in 60% of recordings. CONCLUSION: The range of SpO2 during the first 24 hours of life is similar to that found previously during the first month of life. The clinical significance of the prolonged episodes of desaturation observed justifies further investigation.

The Child-Friendly Healthcare Initiative (CFHI): Healthcare provision in accordance with the UN Convention on the Rights of the Child. Child Advocacy International. Department of Child and Adolescent Health and Development of the World Health Organization (WHO). Royal College of Nursing (UK). Royal College of Paediatrics and Child Health (UK). United Nations Children's Fund (UNICEF).

OBJECTIVE: Although modern medical technology and treatment regimens in well-resourced countries have improved the survival of sick or injured children, most of the world's families do not have access to adequate health care. Many hospitals in poorly resourced countries do not have basic water and sanitation, a reliable electricity supply, or even minimal security. The staff, both clinical and nonclinical, are often underpaid and sometimes undervalued by their communities. In many countries there continues to be minimal, if any, pain control, and the indiscriminate use of powerful antibiotics leads to a proliferation of multiresistant pathogens. Even in well-resourced countries, advances in health care have not always been accompanied by commensurate attention to the child's wider well-being and sufficient concerns about their anxieties, fears, and suffering. In accordance with the United Nations Convention on the Rights of the Child,(1) the proposals set out in this article aim to develop a system of care that will focus on the physical, psychological, and emotional well-being of children attending health care facilities, particularly as inpatients. DESIGN OF THE PROGRAM: To develop in consultation with local health care professionals and international organizations, globally applicable standards that will help to ensure that practices in hospitals and health centers everywhere respect children's rights, not only to survival and avoidance of morbidity, but also to their protection from unnecessary suffering and their informed participation in treatment. Child Advocacy International will liase closely with the Department of Child and Adolescent Health and Development of the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) in the implementation of the pilot scheme in 6 countries. In hospitals providing maternity and newborn infant care, the program will be closely linked with the Baby Friendly Hospital Initiative of WHO/UNICEF that aims to strengthen support for breastfeeding.

Effect of exposure to 15% oxygen on breathing patterns and oxygen saturation in infants: interventional study.

OBJECTIVE: To assess the response of healthy infants to airway hypoxia (15% oxygen in nitrogen). DESIGN: Interventional study. SETTINGS: Infants' homes and paediatric ward. SUBJECTS: 34 healthy infants (20 boys) born at term; mean age at study 3.1 months. 13 of the infants had siblings whose deaths had been ascribed to the sudden infant death syndrome. INTERVENTION: Respiratory variables were measured in room air (pre-challenge), while infants were exposed to 15% oxygen (challenge), and after infants were returned to room air (post-challenge). MAIN OUTCOME MEASURES: Baseline oxygen saturation as measured by pulse oximetry, frequency of isolated and periodic apnoea, and frequency of desaturation (oxygen saturation < or = 80% for > or = 4 s). Exposure to 15% oxygen was terminated if oxygen saturation fell to < or = 80% for > or = 1 min. RESULTS: Mean duration of exposure to 15% oxygen was 6.3 (SD 2.9) hours. Baseline oxygen saturation fell from a median of 97.6% (range 94.0% to 100%) in room air to 92.8% (84.7% to 100%) in 15% oxygen. There was no correlation between baseline oxygen saturation in room air and the extent of the fall in baseline oxygen saturation on exposure to 15% oxygen. During exposure to 15% oxygen there was a reduction in the proportion of time spent in regular breathing pattern and a 3.5-fold increase in the proportion of time spent in periodic apnoea (P < 0.001). There was an increase in the frequency of desaturation from 0 episodes per hour (range 0 to 0.2) to 0.4 episodes per hour (0 to 35) (P < 0.001). In 4 infants exposure to hypoxic conditions was ended early because of prolonged and severe falls in oxygen saturation. CONCLUSIONS: A proportion of infants had episodes of prolonged (< or = 80% for > or = 1 min) or recurrent shorter (< or = 80% for > or = 4 s) desaturation, or both, when exposed to airway hypoxia. The quality and quantity of this response was unpredictable. These findings may explain why some infants with airway hypoxia caused by respiratory infection develop more severe hypoxaemia than others. Exposure to airway hypoxia similar to that experienced during air travel or on holiday at high altitude may be harmful to some infants.

Small airway patency in infants with apparent life-threatening events.

UNLABELLED: A reduction in specific airway conductance has been reported in infants with a history of an apparent life-threatening event (ALTE). It is unclear, however, whether this reflects upper or lower airway narrowing. We performed a controlled study to determine small airway patency in infants with ALTE. Lung function tests were performed in 26 infants with a history of ALTE and 27 healthy controls. Partial expiratory flow-volume curves were obtained during quiet sleep using the rapid chest compression technique; thoracic gas volume (TGV) and expiratory airway resistance (RAW) were measured by whole body plethysmography. Compliance of the respiratory system (Crs) was measured using the single breath occlusion technique. The median maximal flow at functional residual capacity (VmaxFRC) was 85 ml/s (range 10-198 ml/s) in patients and 123 (range 47-316 ml/s) in controls (P = 0.003). VmaxFRC corrected for TGV was 0.5 s(-1) (range 0.06-1.3 s[-1]) and 0.9 s(-1) (range 0.4-1.8 s[-1]), respectively (P = 0.001). TGV, RAW and Crs were not significantly different between patients and controls. CONCLUSION: Reduced small airway patency may play a role in the pathogenesis of ALTE.

Covert video recordings of life-threatening child abuse: lessons for child protection.

OBJECTIVE: To describe historic markers and clinical observations of life-threatening child abuse as diagnosed using covert video surveillance (CVS). DESIGN: A descriptive, retrospective, partially controlled case study. SETTING: Two hospitals (in London and North Staffordshire, UK) receiving referrals for the investigation of apparent life-threatening events (ALTE), with the availability of CVS. PATIENTS: A total of 39 children (age range at CVS, 2 to 44 months; median, 9 months) in whom hospital CVS was used to investigate suspicions of induced illness. Thirty-six were referred for investigation of ALTE, one with suspected epilepsy, one with failure to thrive, and one with suspected strangulation. A control group consisted of 46 children with recurrent ALTE proven on physiologic recordings to be attributable to a natural medical cause (9 attributable to epileptic seizures, and 37 attributable to respiratory problems). INTERVENTION: Collection of historic details from medical, social service, and police records; interagency collaboration in planning, investigations, and management; development and use of CVS as a clinical tool in the investigation of patients in whom there was suspicion of induced illness. OUTCOME: Confirmation of attempted suffocation or other child abuse from CVS. RESULTS: CVS revealed abuse in 33 of 39 suspected cases, with documentation of intentional suffocation observed in 30 patients. Poisonings (with disinfectant or anticonvulsant), a deliberate fracture, and other emotional and physical abuse were also identified under surveillance. The first ALTE occurred at a median age corrected for the expected date of delivery of 3.6 months in the CVS patients and of 0.3 months in controls. Three CVS patients and 27 of the control children (including 20 at <32 weeks' gestation) were born prematurely. Bleeding from the nose and/or mouth was reported in 11 of the 38 patients with ALTE undergoing CVS but in none of the 46 controls. Four patients who had been subjected to recurrent suffocation before CVS had permanent neurologic deficits and/or required anticonvulsant therapy for epileptic seizures resulting from hypoxic cerebral injury. The 39 patients undergoing CVS had 41 siblings, 12 of whom had previously died suddenly and unexpectedly. Eleven of the deaths had been classified as sudden infant death syndrome but after CVS, four parents admitted to suffocating eight of these siblings. One additional sibling who had died suddenly with rotavirus gastroenteritis was reinvestigated after CVS of her sister revealed poisoning, and death was found to be caused by deliberate salt poisoning. Other signs of abuse were documented in the medical, social, and police records of an additional 15 of the siblings. In the 52 siblings of the 46 controls, 2 had died: one from hypoplastic left heart at 5 days and the other suddenly and unexpectedly (classified as sudden infant death syndrome) at 7 weeks. Twenty-three of the abusive parents were diagnosed by a psychiatrist as having personality disorders. CONCLUSIONS: Induced illness is a severe form of abuse that may cause death or permanent neurologic impairment. It may be accompanied by other severe forms of abuse, may result in behavioral disorders, and may be accompanied by immeasurable suffering. Detection of this abuse requires careful history-taking; thorough examination of the health, social, and police records; and close and focused collaboration between hospital and community child health professionals, child psychiatrists, social workers, and police officers. CVS may help investigate suspicions and ensure that children are protected from additional abuse. When parents have failed to acknowledge that they have deceived health professionals, partnership with them in seeking to protect their children may be neither safe nor effective.

Temporal relationship between pauses in nasal airflow and desaturation in preterm infants.

Physiological recordings were undertaken to study the temporal relationship between apnea, defined as pauses in nasal airflow (PNA), and desaturation in preterm infants. Seventeen infants with a history of apnea of prematurity were studied on 21 occasions. Median (range) birthweight was 1,180 g (575-2,475) and gestation was 30 weeks (26-33). Median age at time of study was 10 days (range, 2-52). Arterial beat to beat oxygen saturation (SaO(2)), photoplethysmographic waveform, electrocardiogram, abdominal and ribcage breathing movements, and nasal airflow were recorded. Falls in SaO(2) > or = 3% occurring during or after a PNA > or = 4 seconds were recorded. Episodes of periodic breathing were excluded from this analysis. Four hundred and sixteen episodes of PNA and desaturation were analyzed. Application of a definition of "outliers" for non-parametric data suggested an association when the desaturation occurred up to 7.20 seconds after the end of the PNA for infants nursed in air. For infants on oxygen treatment, a temporal association was suggested when desaturation occurred up to 9.76 seconds after the end of PNA.
