Understanding neonatal bowel obstruction: building knowledge to advance practice

Abdominal Wall Movements Predict Intra-Abdominal Pressure Changes in Rats: A Novel Non-Invasive Intra-Abdominal Pressure Detection Method

(1) Background: As increases in intra-abdominal pressure (IAP) result in irreversible tissue damage, monitoring IAP in critically ill patients using the common urinary bladder catheter method is essential. However, this method can result in complications and is not suitable for very low birth weight neonates. The aim of this study was to establish a non-invasive and accurate method to detect IAP changes using an animal model. (2) Methods: IAP changes via intra-abdominal air application (up to 20 mmHg) were measured in 19 Wistar rats via an intra-abdominally placed intracranial pressure probe. Concurrently, abdominal surface tension was measured using a Graseby capsule (GC). (3) Results: A high correlation between abdominal wall distension and IAP (r = 0.9264, CI 0.9249-0.9279) was found for all subjects. (4) Conclusions: IAP changes in rats can be detected non-invasively using a GC. However, further studies are necessary to assess whether IAP changes can be measured using a GC in the neonatal population.

The nursing care of the surgical neonate

In the last two decades, advancement in neonatal surgery, anesthesia, and intensive care have improved the outcome not only for neonates with complex surgical conditions but also for those preterm infants with combined medical and surgical issues. Infants with surgical problems may remain in the neonatal care setting for weeks or months, and providing ongoing nursing care can be challenging but rewarding. In this article, the authors outline the immediate preoperative management, stabilization, and subsequent postoperative nursing care of the surgical neonate.

Trends in neonatal intestinal obstruction in a developing country, 1996-2005

BACKGROUND

Despite the advances in neonatal surgery, the outcome of neonatal intestinal obstruction (NIO) in many developing countries has been reported to be poor. This study describes the trends in NIO, including the contributory factors in southeast Nigeria.

METHODS

We performed a comparative analysis of 128 consecutive NIO managed from January 1996 to December 2005 at the University of Nigeria Teaching Hospital, Enugu, in southeast Nigeria.

RESULTS

Fifty-five (43.0%) neonates were managed in the first 5 years (group A) and 73 (57.0%) in the last 5 years (group B). Etiology of obstruction did not vary significantly in the two groups. Average duration of symptoms before presentation fell from 5.9 days (group A) to 4.7 days (group B). With exception of Hirschsprung's disease (HD), all other cases required operative treatment. In HD, colostomy rate declined from 44.4% (group A) to 26.7% (group B). More neonates in group B were managed with general anesthesia and perioperative third-generation cephalosporin antibiotics (p < 0.01). While complication rate did not vary significantly in the two groups (group A, 42%; group B, 40.3%), survival improved (group A, 61.8%; group B, 72.6%). Earlier presentation, improved manpower, and use of potent antibiotics may have contributed to the improved outcome. Challenges in the form of lack of neonatal intensive care facilities and dearth of qualified personnel persist.

CONCLUSION

There is a trend toward earlier presentation and increased survival of babies with NIO in our setting. Improving the existing facilities and trained manpower, and establishing collaboration with centers that have excellent results may further encourage the trend.
