Impact of temperature change from admission to day one on neonatal mortality in a low-resource setting

Polyethylene bags before cord clamping in very preterm infants: a randomised controlled trial

OBJECTIVE

Hypothermia on admission to the neonatal intensive care unit (NICU) is associated with an increased risk of death in preterm infants. There are currently no evidence-based recommendations for thermal care before cord clamping (CC). We wished to determine whether placing very preterm infants in a polyethylene bag (PB) before CC, compared with after CC, results in more infants with a temperature in the normal range on NICU admission.

DESIGN

Randomised controlled trial.

SETTING

Tertiary maternity hospital.

PATIENTS

Inborn infants<32 weeks' gestational age (GA).

INTERVENTIONS

Infants were randomly assigned to have a PB placed before or after CC.

MAIN OUTCOME

Rectal temperature within the normal range (36.5°C-37.5°C) on NICU admission.

RESULTS

Between July 2020 and September 2022, 198/220 (90%) eligible infants were enrolled in this study; 99 (44 (44%) girls) were randomly assigned to BEFORE and 99 (53 (54%) girls) to AFTER. Median (IQR) GA 29 (27-31) vs 29 (27-31) weeks, mean (SD) birth weight 1206 (429) vs 1138 (419) g, respectively. The proportion of infants who had normal temperature on NICU admission did not differ between the groups (BEFORE 54/99 (55%) vs AFTER 55/98 (56%), p 0.824). The proportion of infants with a temperature outside of the normal range was similar between the groups; hypothermia (BEFORE 34/99 (34%) vs AFTER 33/98 (34%), hyperthermia (BEFORE 10/99 (10%) vs AFTER 10/98 (10%)).

CONCLUSIONS

Placing a PB before CC did not increase the proportion of preterm infants with normal temperature on NICU admission. A large proportion of preterm infants had abnormal temperature. Further studies on thermoregulation before CC are needed.

Admission Hypothermia and Factors Associated with Mortality among Admitted Hypothermic Preterm Neonates in Neonatal Intensive Care Units of Public Hospitals of Addis Ababa, Ethiopia

Background

Limited knowledge on the proportion of admission hypothermia and factors of death in hypothermic preterm neonates is hindering early and appropriate interventions in Ethiopia. Thus, studies on the proportion of admission hypothermia and factors of death in hypothermic preterm neonates are critical to enhancing preterm infants' survival.

Methods

Hospital-based cross-sectional study was conducted on 398 participants using the systematic sampling method from October 10, 2021, to December 15, 2022. A pretested data extraction tool was used to collect data. EpiData version 4.6 and STATA version 16 were used for data entry and analysis. Multivariable logistic regression analysis evaluated the association between independent and outcome variables with a 95% confidence interval (CI). Hosmer and Lemeshow test and variance inflation factor were assessed to check model fitness and collinearity, respectively. Pvalue < 0.05 was considered statistically significant.

Result

Of the 398 admitted preterm neonates, 331(83.2%) had hypothermia at admission. Factors that were significantly associated with mortality included outborn babies [Adjusted hazard ratio (AOR) = 2.18 : 95% CI (1.03-4.62)], GA less than 32 weeks [AOR = 6.64 : 95% CI (1.87-13.58)], weight less than 1500 gram [AOR = 7.91 : 95% CI (1.21-15.38)], thrombocytopenia [AOR = 3.36 : 95% CI (1.49-7.58)], and kangaroo mother care [AOR = 0.38 : 95% CI (0.16-0.88)].

Conclusion

The proportion of admission hypothermia was high. Outborn babies, birth weight less than 1500 gram, gestational age < 32 weeks, being thrombocytopenic, and lack of kangaroo mother care were identified as risk factors for hypothermic preterm neonatal mortality. Preterm labor prevention, improved inborn delivery, and kangaroo mother care may alleviate the high proportion of admission hypothermia and related mortalities in preterm neonates.

Survival and Predictors of Mortality Among Neonates Admitted to Neonatal Intensive Care Unit at Bombe Primary Hospital, Southern Ethiopia: Institution-Based Retrospective Cohort Study

Background

Neonatal mortality includes all deaths of neonate occurring before the 28th day of life. Neonatal mortality has been declining over two decades in Sub-Saharan Africa, including Ethiopia. The foremost causes of death are preventable and treatable. Regardless, recognizing the predictors may be a crucial step in lowering neonatal mortality. However, evidences on the survival status of neonates and/or neonatal death predictors were limited in Ethiopia, particularly in the study area. Thus, this study aimed to answer these questions.

Methods

An institution-based retrospective cohort study was done among 380 Neonates admitted to the Neonatal Intensive Care Unit at Bombe Primary Hospital from January 1, 2018, to December 31, 2019. Bivariable and multivariable Cox regression analyses were conducted to identify predictors of mortality. Association was summarized using adjusted hazard ratio (AHR), and statistical significances were declared at 95% CI and P-value <0.05. Proportionality assumption was tested by a global test based on Schoenfeld residuals analysis.

Results

The overall incidence of neonatal mortality was 20.8 (95% CI: 15.2, 28.5) per 1000 neonatal days. Late initiation of early breastfeeding (EBF) after 1 hr. [AHR: 2.9; 95% CI: 1.32, 6.37], 5th min APGAR score <5 [AHR: 3; 95% CI: 1.32; 6.88], low birth weight [AHR: 2.59; 95% CI: 1.1,6.26], hypothermia [AHR: 2.6; 95% CI: 1.1, 6.22] and mothers’ time of rupture of membrane >12 hours before delivery [AHR: 2.49; 95% CI: 1.25, 4.97] were increased the risk of neonatal mortality, while cesarean section delivery 91.6% [AHR= 0.084; 95% CI: 0.10, 0.65] and antenatal care (ANC) utilization 61% [AHR: 0.39; 95% CI: 0.15–0.91] decreased the risk of neonatal mortality.

Conclusion

The incidence of neonatal mortality rate was high at the Bombe primary hospital. Therefore, to improve neonatal survival, it is recommended that complications and low birth weight be managed, that early exclusive breastfeeding be initiated, that service quality be improved, and that a continuum of care be ensured.

Risk factors for mortality among neonates admitted to a special care unit in a low-resource setting

Background

Although under-5 mortality has decreased in the last two decades, neonatal mortality remains a global health challenge. Despite achieving notable progress, Ethiopia has still one of the highest neonatal mortality rates worldwide. We aimed to assess the risk factors for mortality among neonates admitted to a special care unit in a referral hospital in rural Ethiopia.

Methods

This was a retrospective observational study including all 4182 neonates admitted to the special care unit of the St. Luke Wolisso Hospital (Ethiopia) from January 2014 to December 2017. Data were retrieved from hospital charts and entered in an anonymized dataset. A logistic regression model was applied to identify predictors of mortality and effect sizes were expressed as odds ratios with 95% confidence intervals.

Results

Proportion of deaths was 17% (709/4182 neonates). Neonates referred from other health facilities or home (odds ratio 1.52, 95% confidence interval 1.21 to 1.91), moderate hypothermia at admission (odds ratio 1.53, 95% confidence interval 1.09 to 2.15) and diagnosis of late-onset sepsis (odds ratio 1.63, 95% confidence interval 1.12 to 2.36), low birthweight (odds ratio 2.48, 95% confidence interval 2.00 to 3.09), very low birthweight (odds ratio 11.71, 95% confidence interval 8.63 to 15.94), extremely low birthweight (odds ratio 76.04, 95% confidence interval 28.54 to 263.82), intrapartum-related complications (odds ratio 4.69, 95% confidence interval 3.55 to 6.20), meconium aspiration syndrome (odds ratio 2.34, 95% confidence interval 1.15 to 4.43), respiratory distress (odds ratio 2.25, 95% confidence interval 1.72 to 2.95), other infections (odds ratio 1.92, 95% confidence interval 1.31 to 2.81) or malformations (odds ratio 2.32, 95% confidence interval 1.49 to 3.57) were associated with increased mortality. Being admitted in 2017 vs. 2014 (odds ratio 0.71, 95% confidence interval 0.52 to 0.97), and older age at admission (odds ratio 0.95, 95% confidence interval 0.93 to 0.97) were associated with decreased likelihood of mortality.

Conclusions

The majority of neonatal deaths was associated with preventable and treatable conditions. Education on neonatal resuscitation and postnatal management, and the introduction of an on-call doctor for high-risk deliveries might have contributed to the reduction in neonatal mortality over time.
