Insights
Gastrointestinal perforation is a critical threat to extremely low birth weight infants. Sepsis and hemodynamically significant patent ductus arteriosus are key risk factors, while treatments like ibuprofen and blood transfusions improve survival rates.
Area of Science:
- Neonatology
- Pediatric Surgery
- Critical Care Medicine
Background:
- Gastrointestinal perforation (GIP) in extremely low birth weight infants (ELBWI) is a life-threatening condition with high mortality.
- Characterized by rapid onset and severe complications, GIP necessitates understanding its risk factors and management strategies.
Purpose of the Study:
- To investigate the clinical characteristics of pneumoperitoneum in ELBWI.
- To identify risk factors for GIP in very low birth weight preterm infants.
- To share surgical experiences in managing GIP in ELBWI.
Main Methods:
- Retrospective study of ELBWI with GIP (birth weight <1000 g) from 2014-2021.
- Risk factor identification using multiple logistic regression analysis.
- Survival analysis using Kaplan-Meier and Cox multivariate regression models.
Main Results:
- Significant risk factors for GIP in ELBWI include hemodynamically significant patent ductus arteriosus (hsPDA) and sepsis.
- Intraventricular hemorrhage, sepsis, and GIP negatively impact ELBW infant survival.
- Ibuprofen and blood transfusions demonstrate beneficial effects on survival.
Conclusions:
- GIP significantly threatens ELBW infant survival, with hsPDA and sepsis as predisposing factors.
- Distinct clinical characteristics of GIP necessitate tailored surgical interventions.
- Understanding risk factors and survival predictors is crucial for managing GIP in ELBWI.
Background:
Gastrointestinal perforation in extremely low birth weight infants, characterized by its rapid onset, multiple complications, and critical condition, poses a significant risk of infant mortality. The aim of this study was to investigate the clinical characteristics of pneumoperitoneum in extremely low birth weight infants (ELBWI) and explore the risk factors associated with gastrointestinal perforation in very low birth weight preterm infants. Additionally, we shared our surgical experiences in managing gastrointestinal perforation among extremely low birth weight infants.
Methods:
The Department of Neonatology at Chengdu Women and Children's Central Hospital conducted a retrospective study on gastrointestinal perforation in extremely low birth weight infants (birth weight <1000 g) who were admitted between 2014 and 2021. After baseline analysis and comparing it with the control group, we identified the risk factors associated with gastrointestinal perforation in ELBWI by multiple logistic regression analysis. The Kaplan-Meier analysis was performed to assess the adverse effect of gastrointestinal perforation for survival in ELBW infants. Cox multivariate regression analysis was used to evaluate hazard level of different variables for ELBW infants survival.
Results:
Hemodynamically significant patent ductus arteriosus (hsPDA)(p = 0.043, OR = 2.779) and sepsis (p = 0.014, OR = 2.265) were significant risk factors for gastrointestinal perforation in extremely low birth weight infants. The Cox proportional hazard model revealed that intraventricular hemorrhage (HR = 2.854, p<0.001) Sepsis (HR = 1.645, p = 0.015) and gastrointestinal perforation (HR = 1.876, p = 0.008) had detrimental effects on the survival of extremely low birth weight infants; conversely, ibuprofen (HR = 0.304, p<0.001) and blood transfusion (HR = 0.372, p<0.001) are beneficial factors for their survival. The preoperative indicators of infection in infants with spontaneous intestinal perforation (SIP) were significantly better than those in the necrotizing enterocolitis (NEC) group (p < 0.05).
Conclusions:
Gastrointestinal perforation poses a significant threat the survival of extremely low birth weight (ELBW) infants, with hsPDA and sepsis serving as predisposing factors for gastrointestinal perforation. The gastrointestinal perforation caused by various diseases exhibits distinct clinical characteristics, necessitating tailored surgical approaches based on operative conditions.
