Effectiveness of a campaign to implement chlorhexidine use for newborns in rural Haiti.

BACKGROUND: Chlorhexidine topical cord application is recommended to prevent umbilical cord infections in newborns delivered at home in low-resource settings. A community campaign introducing chlorhexidine for the first time in Haiti was developed. Traditional birth attendants (TBAs) were identified as implementers since they typically cut newborns' cords. TBAs were trained to apply chlorhexidine to the cord and demonstrate this procedure to the mother. Concurrently TBAs explained reasons for using chlorhexidine exclusively instead of traditional cord care practices. The campaign's effectiveness was evaluated 7-10 days post-delivery using a survey administered by community health workers (CHWs) to 198 mothers. RESULTS: Nearly all mothers heard about chlorhexidine use and applied it as instructed. Most mothers did not initially report using traditional cord care practices. With further probing, the majority reported covering the cord but few applied an unhygienic substance. No serious cord infections were reported. CONCLUSION: The campaign was highly successful in reaching mothers and achieving chlorhexidine use. In this study, the concomitant use of traditional cloth coverings or bindings of the cord did not appear harmful; however more research is needed in this area. This campaign provides a model for implementing chlorhexidine use, especially where trained TBAs and CHWs are present.

Short communication: The effect of 4 antiseptic compounds on umbilical cord healing and infection rates in the first 24 hours in dairy calves from a commercial herd.

The objective of this study was to compare the effect of 4 antiseptic compounds on the healing rate and incidence of infection of umbilical cords in newborn calves (n=60). Late gestation Jersey cows were monitored at a commercial farm (Sioux Jersey, Salix, IA) and newborn purebred (n=30) and crossbred (n=30) calves were obtained within 30min after birth. Calves were alternately assigned by birth order to 4 treatment groups: 7% tincture of iodine, 0.1% chlorine created using a novel chlorine disinfectant technology, chlorohexidine gluconate 4.0% wt/vol, and 10% trisodium citrate. Prior to dipping (within 30min of birth), diameter of the umbilical cords (as an indicator of cord drying and healing) were determined using digital calipers. In addition, as an indicator of umbilical infections, surface temperature of the umbilical stump (along with a reference point at the midpoint of the sternum) was determined using a dual-laser infrared thermometer. These measurements were all repeated at 24±1 h of age. All data were analyzed using mixed model methods. All models included fixed effects of breed (Jersey or Jersey cross), sex (bull or heifer), and treatment. Fixed effect interactions were not included in the statistical model due to the relatively small sample size. No treatment differences were noted for healing rate of umbilical cords. Initially, mean umbilical cord diameter was 22.84±3.89mm and cords healed to a mean diameter of 7.64±4.12mm at 24 h of age. No umbilical infections were noted for calves on any treatment during the course of this study. Mean surface temperature of the umbilical stump was 33.1±2.2°C at birth (1.5±1.6°C higher than the sternal reference temperature), and at 24±1 h of age the mean temperature of the umbilical stump was 33.0±4.3°C (0.5±1.8°C lower than the sternal reference temperature). These data suggest that these antiseptic compounds are equally effective for preventing infections and permitting healing of the umbilical cord when used within 30min of birth.

Newborn cord care practices in Haiti.

Newborn cord infections commonly lead to neonatal sepsis and death, particularly in low-resource countries where newborns may receive unhygienic cord care. Topical application of chlorhexidine to the newborn's cord has been shown to prevent infection. Such benefits may be particularly important in Haiti. We explored current cord care practices by conducting a qualitative study using five focus groups among key community stakeholders (mothers of newborns/children under age two years, pregnant women, traditional birth attendants, community health workers, traditional healers) in Petit-Goâve, Haiti. Data collection was guided by the Health Belief Model. Results suggest community stakeholders recognise that infants are susceptible to cord infection and that cord infection is a serious threat to newborns. Long-held traditional cord care practices are potential barriers to adopting a new cord care intervention. However, all groups acknowledged that traditional practices could be harmful to the newborn while expressing a willingness to adopt practices that would protect the newborn. Results demonstrate potential acceptability for altering traditional cord care practices among neonatal caretakers in Haiti. An informational campaign designed to educate local health workers and new mothers to eliminate unhygienic cord applications while promoting chlorhexidine application may be a strong approach for preventing neonatal cord infections.

Two methods of cord care in high-risk newborns: their effects on hydration, temperature, pH, and floras of the cord area.

This randomized clinical study explored the effects of two cord care methods on hydration, temperature, pH, and floras at the cord area in high-risk newborns. One group used the water method; and the other group used the alcohol method. Seventy-two newborns, including premature newborns, in the neonatal intensive care unit (NICU) of a university-affiliated hospital in South Korea were enrolled from August 2011 to May 2012. Hydration, temperature, pH, and floras were measured daily until the cords fell off. The results showed no difference between the groups in hydration, temperature, pH, and the colonization of floras, but cord detachment in the alcohol group took 2 days longer (12.8 [5.7] days) than in the water group (10.9 [4.1] days). Our findings suggest that the clean-and-dry method of cord care, which uses water, could be sufficient, possibly even better than alcohol in maintaining the physiologic surface milieu of the cord area with less chance of infection and manipulation in NICUs with optimal infection control.

Topical application of chlorhexidine to neonatal umbilical cords for prevention of omphalitis and neonatal mortality in a rural district of Pakistan: a community-based, cluster-randomised trial.

BACKGROUND: Umbilical cord infection (omphalitis) is a risk factor for neonatal sepsis and mortality in low-resource settings where home deliveries are common. We aimed to assess the effect of umbilical-cord cleansing with 4% chlorhexidine (CHX) solution, with or without handwashing with antiseptic soap, on the incidence of omphalitis and neonatal mortality. METHODS: We did a two-by-two factorial, cluster-randomised trial in Dadu, a rural area of Sindh province, Pakistan. Clusters were defined as the population covered by a functional traditional birth attendant (TBA), and were randomly allocated to one of four groups (groups A to D) with a computer-generated random number sequence. Implementation and data collection teams were masked to allocation. Liveborn infants delivered by participating TBAs who received birth kits were eligible for enrolment in the study. One intervention comprised birth kits containing 4% CHX solution for application to the cord at birth by TBAs and once daily by family members for up to 14 days along with soap and educational messages promoting handwashing. One intervention was CHX solution only and another was handwashing only. Standard dry cord care was promoted in the control group. The primary outcomes were incidence of neonatal omphalitis and neonatal mortality. The trial is registered with ClinicalTrials.gov, number NCT00682006. FINDINGS: 187 clusters were randomly allocated to one of the four study groups. Of 9741 newborn babies delivered by participating TBAs, factorial analysis indicated a reduction in risk of omphalitis with CHX application (risk ratio [RR]=0·58, 95% CI 0·41-0·82; p=0·002) but no evidence of an effect of handwashing (RR=0·83, 0·61-1·13; p=0·24). We recorded strong evidence of a reduction in neonatal mortality in neonates who received CHX cleansing (RR=0·62, 95 % CI 0·45-0·85; p=0·003) but no evidence of an effect of handwashing promotion on neonatal mortality (RR=1·08, 0·79-1·48; p=0·62). We recorded no serious adverse events. INTERPRETATION: Application of 4% CHX to the umbilical cord was effective in reducing the risk of omphalitis and neonatal mortality in rural Pakistan. Provision of CHX in birth kits might be a useful strategy for the prevention of neonatal mortality in high-mortality settings. FUNDING: The United States Agency for International Development.

Comparison of olive oil and dry-clean keeping methods in umbilical cord care as microbiological.

The application of olive oil is one of the traditional practices used in umbilical cord care in Turkey. The study was conducted experimentally, so as to compare microbiologically the efficacy of olive oil use and keeping the stump dry. Data were obtained using a personal information form and an omphalitis follow-up form, as well as from cultures taken from the infants' umbilical cords. Cultures were taken from the neonates' umbilical cords at three different times. The Pearson chi-square test, student t test, percentages, and averages were used for statistical data analysis. The average time for separation is 9.46 days. For the control group, this period is 9.8 days, while for the study group, it is 9.1, lacking a statistically significant difference between the two groups (P > 0.05). However, when the cut-off point for umbilical cord detachment is set at 10 days, the cords of 71.6% of the neonates in the study group, compared with 55.6% of the control group, are observed to have separated before 10 days, representing a significant difference between the groups (P < 0.05). In all of the cultures collected, growth was noted in 35.9% of the study group and 33.3% of the control group. The correlation between the method used for the care of the cord and the total culture results was not statistically significant (P > 0.05). Olive oil can be used in the umbilical cord care of neonates under appropriate conditions; we recommended that this investigation be repeated on expanded sample groups.

Impact of clean delivery-kit use on newborn umbilical cord and maternal puerperal infections in Egypt.

This cross-sectional cohort study explored the impact of the use of clean delivery-kit (CDK) on morbidity due to newborn umbilical cord and maternal puerperal infections. Kits were distributed from primary-care facilities, and birth attendants received training on kit-use. A nurse visited 334 women during the first week postpartum to administer a structured questionnaire and conduct a physical examination of the neonate and the mother. Results of bivariate analysis showed that neonates of mothers who used a CDK were less likely to develop cord infection (p = 0.025), and mothers who used a CDK were less likely to develop puerperal sepsis (p = 0.024). Results of multiple logistic regression analysis showed an independent association between decreased cord infection and kit-use [odds ratio (OR) = 0.42, 95% confidence interval (CI) 0.18-0.97, p = 0.041)]. Mothers who used a CDK also had considerably lower rates of puerperal infection (OR = 0.11, 95% CI 0.01-1.06), although the statistical strength of the association was of borderline significance (p = 0.057). The use of CDK was associated with reductions in umbilical cord and puerperal infections.

Neonatal tetanus--Montana, 1998.

Neonatal tetanus (NT) is a severe, often fatal disease caused by a toxin of Clostridium tetani, a ubiquitous spore-forming bacterium found in high concentrations in soil and animal excrements. NT is associated with nonsterile delivery and umbilical cord-care practices for newborns of mothers with antitoxin levels insufficient to protect the newborn by transplacental transfer of maternal antibody. In 1997, NT accounted for an estimated 277,400 deaths worldwide but is rare in the United States. During 1995-1997, of 124 tetanus cases reported in the United States, only one occurred in a neonate. This report summarizes the investigation in March 1998 of an NT case by the Missoula City-County Health Department (MCCHD) and the Montana Department of Health and Human Services (MDHHS). The findings indicated that tetanus in a newborn of an unvaccinated mother occurred after application of nonsterile clay to the umbilical cord.

The efficacy of different umbilical cord care regimens: an in vitro study on their drying and antimicrobial effect.

BACKGROUND: Topical regimens have been used for umbilical cord care for different purposes, but their drying efficacy has rarely been statistically analyzed. We designed an in vitro study with six regimens to determine which one can achieve the best drying and antimicrobial effects in umbilical cord care. METHODS: Twenty-seven umbilical cords were resected when babies were born. Each cord was cut into seven segments in appropriate length and randomly labeled to seven groups. Six regimens including 75% alcohol, 90% alcohol, tincture povidone-iodine, aqua povidone-iodine, Chinese herbs, and one powder agent (M) were used topically on six groups of umbilical cords once daily. The control group received no treatment. Daily weight of the cords was recorded for 7 days, and bacterial culture was performed on the sixth day. RESULTS: All study groups presented similar algebraic functional relationship between weight change and time. The drying effect occurred mostly within the first 3 days (weight loss 88.6%), especially on the first day (62.1%). Mean ratio of the final weight/initial weight was 10.2%. Significant day-by-day weight loss was noted from day 1 to day 5 (p < 0.001). Both aqua and tincture povidone-iodine groups showed not only satisfied drying effect but also significantly better antimicrobial effect than other groups. CONCLUSIONS: Povidone-iodine has both good drying and antimicrobial effects in umbilical cord care. As the topical use of povidone-iodine has been reported to relate to transient neonatal hypothyroidism, we suggest it to be used only as a good substitute if there are signs of umbilical cord infection.

Risk factors of neonatal tetanus in Senegal.

A case-control study for evaluating the risk factors of neonatal tetanus was conducted in a rural area of Senegal under demographic surveillance (Niakhar). Some 45 neonatal tetanus deaths that occurred in the study area between March 1983 and March 1986 were investigated. They were matched with 187 controls. Neonatal tetanus accounted for one-third of all neonatal deaths; mortality from neonatal tetanus was 16/1000 livebirths. The effect of various demographic, socioeconomic, epidemiological and behavioural factors was investigated in a multivariate analysis using linear logistic regression. There was no difference associated with socioeconomic factors between cases and controls. Factors associated with the skill and behaviour of birth attendant and mother were highly significant and were associated with high odds ratio (OR) and included whether the hands of the person cutting the cord were washed with soap (OR = 5.22; p = 0.001); whether the person who dressed the cord was skilled (OR = 4.71; p = 0.012); whether the age of the mother was less than 18 years (OR = 7.03; p = 0.027) and whether the birth attendant arrived before delivery (OR = 4.15, p = 0.023). Conversely, the type of tool used to cut the cord did not have a significant effect (p = 0.239). Data analysis suggests that a main source of Clostridium tetani may be the hands of the birth attendant and that the main mode of contamination may be the dressing of the wound stump. Results suggest that teaching mothers and birth attendants simple hygienic principles and basic techniques may have a significant impact on neonatal tetanus mortality.

Neonatal tetanus: mode of infection, prevalence, and prevention in southern Sudan.

Neonatal tetanus affects 1 in every 82 and kills 1 in every 110 infants born in the town of Juba, southern Sudan. It is also an important cause of death in adult life both in southern Sudan and in many other regions of the developing world. One vehicle of infection could be the fine string-like roots used to tie the cord. To prevent neonatal tetanus governments and aid-giving agencies should distribute to women and midwives kits containing a sterile blade, a sterile ligature, two or three sterile adhesive dressings for the umbilical stump, and two or three sterile swabs.
