Comparison of Olive Oil and Dry-Clean Keeping Methods in Umbilical Cord Care as Microbiological

The impact of umbilical cord care education given to Primiparous mothers on cord separation time: A randomized controlled study

PURPOSE

This study aims to determine the impact of umbilical cord care education given to primiparous mothers on cord separation time.

DESIGN AND METHODS

This randomized controlled trial was conducted according to the Consolidated Standards of Reporting Trials (CONSORT) guidelines. The mothers constituting the research sample were divided into two groups, the control group and the education group, and cord care and cord separation times were measured.

RESULTS

The mean age of the mothers was 28.72 ± 4.86 years (min. 20 years, max. 40 years). There was no difference in age, gestational week of the baby, birth weight of the baby, gender of the baby and mode of delivery of the mother between the mothers in the control and education groups. While the cord separation time was 10.97 ± 0.320 days in the babies in the control group, it was 6.60 ± 0.177 days in the babies in the education group. A statistically significant difference was found between the duration of cord separation of the babies in the control and education groups.

CONCLUSIONS

This study showed that giving umbilical cord care education to primiparous mothers reduces umbilical cord separation time.

PRACTICE IMPLICATIONS

It is recommended that pediatric nurses provide education on umbilical cord care and the goals and methods of application of care practices, especially to primiparous mothers.

CLINICAL REGISTRATION

This study was registered at the U.S. National Library of Medicine Clinical Trials (code: NCT05573737).

Bathing or Not Bathing: Which Is Better for Umbilical Cord Separation Time and Bacterial Colonization in Neonates?

Background: Sepsis is the third cause of death in the first month of life, and the umbilical cord is an important source for sepsis Objectives: We compared the effects of bathing or not bathing on bacterial colonization and cord separation time. Methods: A quasi-experimental study assessed term newborns at Golestan hospital, Tehran, Iran, from 2019 to 2020 in three groups. Bath (B) group included neonates who were bathed with tub water every two days (n = 90). Clean product (CP) group neonates were bathed with cleaners every two days (n = 87). Dry care cord (D) group neonates were not bathed during the first 10 days (n = 63). Periumbilical cord swabs were collected on the 10th day and cultured in blood agar and Eosin methylene blue agar. Bacterial sensitivity tests were done by disk diffusion. Results: The average time to cord separation was 8.2 ± 1.74 days (group B: 9.1 ± 2.1 days, group CP: 8.7 ± 1.82 days, group D: 6.8 ± 1.3 days), which was shorter in group D (P= 0.048). The positive culture rates were 77.8% in group B, 78.1% in group CP, and 74.6% in group D, which were not significantly different between the groups (P = 0.073). Staphylococcus aureus was the most common isolated species. Staphylococcus epidermis and Escherichia coli were the other most common species. Conclusions: Bathing with or without cleaners is safe. No-bath and water bath with or without cleaners had no difference in the rate and type of bacterial culture in umbilical cord but the cord separation time was shorter in the no-bath group. Therefore, in the first week, if a mother does not believe in bathing her baby, she should not be denounced and told that she did something wrong with cord hygiene.

Umbilical Cord Care in the Newborn Infant

Postpartum infections remain a leading cause of neonatal morbidity and mortality worldwide. A high percentage of these infections may stem from bacterial colonization of the umbilicus, because cord care practices vary in reflection of cultural traditions within communities and disparities in health care practices globally. After birth, the devitalized umbilical cord often proves to be an ideal substrate for bacterial growth and also provides direct access to the bloodstream of the neonate. Bacterial colonization of the cord not infrequently leads to omphalitis and associated thrombophlebitis, cellulitis, or necrotizing fasciitis. Various topical substances continue to be used for cord care around the world to mitigate the risk of serious infection. More recently, particularly in high-resource countries, the treatment paradigm has shifted toward dry umbilical cord care. This clinical report reviews the evidence underlying recommendations for care of the umbilical cord in different clinical settings.

Umbilical cord antiseptics for preventing sepsis and death among newborns

BACKGROUND

The umbilical cord is a structure made of blood vessels and connective tissue that connects the baby and placenta in utero. The umbilical cord is cut after birth, which separates the mother and her baby both physically and symbolically. Omphalitis is defined as infection of the umbilical cord stump. Tracking of bacteria along the umbilical vessels may lead to septicaemia that can result in neonatal morbidity and mortality, especially in developing countries.

OBJECTIVES

To determine the effect of application of antimicrobials on newborn's umbilical cord versus routine care for prevention of morbidity and mortality in hospital and community settings.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (1 October 2012). In addition, we also searched LILACS (1982 to 11 October 2012) and HERDIN NeON (October 2012)

SELECTION CRITERIA

We included randomized, cluster-randomized and quasi-randomized controlled trials of topical cord care compared with no topical care, and comparisons between different forms of care.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion, trial quality and subsequently extracted data. Data were checked for accuracy.

MAIN RESULTS

The search identified 77 trials. We included 34 trials in the review involving 69,338 babies, five studies are awaiting classification and there are two ongoing community trials. Included studies were conducted in both developed and developing countries. Among the 34 included trials, three were large, cluster-randomized trials conducted in community settings in developing countries and 31 studies were conducted in hospital settings mostly in developed countries. Data for community and hospital studies were analyzed separately. The three trials conducted in community settings contributed 78% of the total number of children included in this review. Of the trials conducted in hospital settings, the majority had small sample sizes. There were 22 different interventions studied across the included trials and the most commonly studied antiseptics were 70% alcohol, triple dye and chlorhexidine.Only one antiseptic, chlorhexidine was studied in community settings for umbilical cord care. Three community trials reported data on all-cause mortality that comprised 1325 deaths in 54,624 participants and combined results showed a reduction of 23% (average risk ratio (RR) 0.77, 95% confidence interval (CI) 0.63 to 0.94, random-effects, T² = 0.02, I² = 50%) in the chlorhexidine group compared with control. The reduction in omphalitis ranged from 27% to 56% depending on the severity of infection. Cord separation time was increased by 1.7 days in the chlorhexidine group compared with dry cord care (mean difference (MD) 1.75 days, 95% CI 0.44 to 3.05, random-effects, T² = 0.88, I² = 100%). Washing of umbilical cord with soap and water was not advantageous compared with dry cord care in community settings.Among studies conducted in hospital settings, no study reported data for mortality or tetanus. No antiseptic was advantageous to reduce the incidence of omphalitis compared with dry cord care in hospital settings. Topical triple dye application reduced bacterial colonization with Staphylococcus aureus compared with dry cord care (average RR 0.15, 95% CI 0.10 to 0.22, four studies, n = 1319, random-effects, T² = 0.04, I² = 24%) or alcohol application (average RR 0.45, 95% CI 0.25 to 0.80, two studies, n = 487, random-effects, T² = 0.00, I² = 0%). There was no advantage of application of alcohol and triple dye for reduction of colonization with streptococcus. Topical alcohol application was advantageous in reduction of colonization with Enterococcus coli compared with dry cord care (average RR 0.73, 95% CI 0.58 to 0.92, two studies, n = 432, random-effects, T² = 0.00, I² = 0%) and in a separate analysis, triple dye increased the risk of colonization compared with alcohol (RR 3.44, 95% CI 2.10 to 5.64, one study, n = 373). Cord separation time was significantly increased with topical application of alcohol (MD 1.76 days, 95% CI 0.03 to 3.48, nine studies, n = 2921, random-effects, T² = 6.54, I² = 97%) and triple dye (MD 4.10 days, 95% CI 3.07 to 5.13, one study, n = 372) compared with dry cord care in hospital settings. The number of studies was insufficient to make any inference about the efficacy of other antiseptics.

AUTHORS' CONCLUSIONS

There is significant evidence to suggest that topical application of chlorhexidine to umbilical cord reduces neonatal mortality and omphalitis in community and primary care settings in developing countries. It may increase cord separation time however, there is no evidence that it increases risk of subsequent morbidity or infection.There is insufficient evidence to support the application of an antiseptic to umbilical cord in hospital settings compared with dry cord care in developed countries.

Topical umbilical cord care for prevention of infection and neonatal mortality

Umbilical cord care varies often reflecting community or health-worker beliefs. We undertook a review of current evidence on topical umbilical cord care. Study quality was assessed using the Grading of Recommendations, Assessment, Development and Evaluation system, and a meta-analysis was conducted for comparable trials. Available moderate-quality to high-quality evidence indicate that cord cleansing with 4% chlorhexidine may reduce the risk of neonatal mortality and sepsis (omphalitis) in low-resource settings.
