Management of neonatal hypoglycaemia in a tertiary maternity unit-A multidisciplinary quality improvement project

AIM

Improved identification and treatment of infants at risk of hypoglycaemia using evidence-based guidelines.

METHODS

Design: Prospective, multidisciplinary quality improvement project (QIP).

SETTING

Tertiary maternity hospital, Dublin (2016-2023).

SUBJECTS

Infants at risk for neonatal hypoglycaemia.

INTERVENTION

Plan-Do-Study-Act methodology. A hospital-wide survey and ongoing audit informed our initiatives including staff education, antenatal maternal education and standardisation of equipment. Our guidelines were continually evaluated and updated based on emerging evidence.

MAIN OUTCOME MEASURES

Neonatal unit (NNU) admissions, adherence to guidelines and use of glucose gel.

RESULTS

NNU admissions decreased by 70%, from 3% (118/3883) to 0.9% (34/3806 infants). The number requiring an IV glucose bolus reduced from 25% (29/118) to 6% (2/34). Improved antenatal education, antenatal expression of colostrum and early and frequent feeding also contributed to a reduction in glucose gel use of 94% (1009 tubes in 2018-v-62 in 2022). There were no adverse side effects related to hypoglycaemia.

CONCLUSION

Our QIP resulted in a significant reduction in NNU admissions leading to significant cost reductions and NNU workload. More importantly, this resulted in less maternal-infant separation and potentially less parental anxiety and a more supportive environment for breastfeeding. These low-cost initiatives can be implemented in other tertiary maternity hospitals to improve maternity and newborn care.

Youngest survivor of perinatal infection by Eikenella corrodens : case analysis and literature review highlighting the merits of placental swab culture

Eikenella corrodens has been noted as a causative organism in both neonatal and perinatal sepsis. Positivity of blood cultures at birth among preterm infants may be influenced by the maternal use of peripartum antimicrobials and a normal C-reactive protein result within the first 24 hours need not always reflect the absence of fetal invasion by the highly pathogenic organisms. For these reasons, supportive and adjunctive approaches such as appropriately collected placental swabs for culture would be of value in optimizing the antimicrobial choice for sick preterm infants during the early neonatal period. Fetal infection by E. corrodens detected by placental swab culture influencing antimicrobial management of an extremely premature infant with sepsis is described. Management of the youngest premature survivor with the lowest birthweight among the reported cases in English language of neonatal E. corrodens infection is summarized and literature is reviewed. The value of placental swab, which is often underused, is highlighted in this review.

A quick and efficient system for antibiotic-free expression of heterologous genes in tobacco roots

Requirement for antibiotic-resistance selection markers and difficulty in identifying transgenes with the highest expression levels remain the major obstacles for rapid production of recombinant proteins in plants. An alternative approach to producing transgenic plants free of antibiotic-resistance markers is the phenotypic-based selection with root-proliferation genes (rol genes) of Agrobacterium rhizogenes. By using Agrobacterium tumefaciens harboring the pRYG transformation vector with a cluster of rol genes linked to a heterologous gene of interest, we have developed a rapid transformation tool using hairy root formation as a selection marker. The expression of beta-glucuronidase in newly induced transgenic tobacco roots could be detected as early as 12 days after inoculation. Higher levels of transgene expression in the roots correlated positively with the rates of root elongation on hormone-free medium and thus could be used for positive selection. When tobacco plants were transformed with pRYG harboring the expression cassette for secreted alkaline phosphatase (SEAP), the release of SEAP from roots of the fully regenerated transgenic plants could be quantified at rates as high as 28 microg/g root dry weight per day.

An audit of subcutaneous syringe drivers in a non-specialist hospital

The use of syringe drivers as a method of drug delivery to control symptoms in palliative care is a common and accepted practice, but one which has evolved rather than been subject to close multiprofessional scrutiny and guideline formation. There is evidence that adverse incidents may arise as a result of syringe driver use (Medical Devices Agency (MDA), 1998), for example, errors in drug calculations, drug stability, equipment failure (including disconnection) and the wrong rate of infusion. Inadequate user training, poor servicing of equipment and inadequate documentation and record keeping are all thought to be contributing factors (MDA, 1998). In the hospital where this audit was carried out, syringe drivers are used to administer drugs to patients with cancer during the palliative phase of illness. The purpose of this clinical audit was to establish the standard of current practice in wards where syringe drivers were being used. A retrospective study of 13 cases of syringe driver use is presented. The results highlight many areas of unregulated practice with regard to setting up, monitoring and maintenance of syringe drivers. The choice of drugs and doses prescribed, evaluation of treatment responses and review of treatment regimens were also areas of concern. Guidelines for the use of syringe drivers in non-specialist hospitals are put forward.
