What impact did a Paediatric Early Warning system have on emergency admissions to the paediatric intensive care unit? An observational cohort study

Summary The ideology underpinning Paediatric Early Warning systems (PEWs) is that earlier recognition of deteriorating in-patients would improve clinical outcomes. Objective To explore how the introduction of PEWs at a tertiary children's hospital affects emergency admissions to the Paediatric Intensive Care Unit (PICU) and the impact on service delivery. To compare ‘in-house’ emergency admissions to PICU with ‘external’ admissions transferred from District General Hospitals (without PEWs). Method A before-and-after observational study August 2005–July 2006 (pre), August 2006–July 2007 (post) implementation of PEWs at the tertiary children's hospital. Results The median Paediatric Index of Mortality (PIM2) reduced; 0.44 vs 0.60 (p < 0.001). Fewer admissions required invasive ventilation 62.7% vs 75.2% (p = 0.015) for a shorter median duration; four to two days. The median length of PICU stay reduced; five to three days (p = 0.002). There was a non-significant reduction in mortality (p = 0.47). There was no comparable improvement in outcome seen in external emergency admissions to PICU. A 39% reduction in emergency admission total beds days reduced cancellation of major elective surgical cases and refusal of external PICU referrals. Conclusions Following introduction of PEWs at a tertiary children's hospital PIM2 was reduced, patients required less PICU interventions and had a shorter length of stay. PICU service delivery improved

Pilot Study Comparing Closed Versus Open Tracheal Suctioning in Postoperative Neonates and Infants With Complex Congenital Heart Disease

Objectives: To determine the hemodynamic effect of tracheal suction method in the first 36 hours after high-risk infant heart surgery on the PICU and to compare open and closed suctioning techniques. Design: Pilot randomized crossover study. Setting: Single PICU in United Kingdom. Participants: Infants undergoing surgical palliation with Norwood Sano, modified Blalock-Taussig shunt, or pulmonary artery banding in the first 36 hours postoperatively. Interventions: Infants were randomized to receive open or closed (in-line) tracheal suctioning either for their first or second study tracheal suction in the first 36 hours postoperatively. Measurements and Main Results: Twenty-four infants were enrolled over 18 months, 11 after modified Blalock-Taussig shunt, seven after Norwood Sano, and six after pulmonary artery banding. Thirteen patients received the open suction method first followed by the closed suction method second, and 11 patients received the closed suction method first followed by the open suction method second in the first 36 hours after their surgery. There were statistically significant larger changes in heart rate (p = 0.002), systolic blood pressure (p = 0.022), diastolic blood pressure (p = 0.009), mean blood pressure (p = 0.007), and arterial saturation (p = 0.040) using the open suction method, compared with closed suctioning, although none were clinically significant (defined as requiring any intervention). Conclusions: There were no clinically significant differences between closed and open tracheal suction methods; however, there were statistically significant greater changes in some hemodynamic variables with open tracheal suctioning, suggesting that closed technique may be safer in children with more precarious physiology.

Endotracheal Suctioning of the Critically Ill Child

Endotracheal suctioning is an essential intervention for the care of an intubated child and is one of the most commonly performed interventions in pediatric intensive care. Despite this, much of the research related to endotracheal suctioning is dated and the bulk of it conducted in preterm infants and adults. This paper will review research related to endotracheal suctioning that involves or relates to children in intensive care to provide a current review of the literature in this field. It will conclude with recommendations for practice where possible and identify areas for further research

The effect of nursing interventions on the intracranial pressure in paediatric traumatic brain injury.

The aim of this research was to investigate the effect of five selected intensive care nursing interventions on the intracranial pressure (ICP) of moderate to severe traumatic brain-injured children in intensive care. The physiological effects of many nursing interventions in paediatric intensive care (PIC) are not known. This results in the lack of an evidence base for many PIC nursing practices. Prospective observational cohort study conducted over 3 years in a single tertiary referral paediatric intensive care unit (PICU) in the North West of England. Five selected commonly performed nursing interventions were studied: endotracheal suctioning and manual ventilation (ETSMV), turning via a log-rolling (LR) approach, eye care, oral care and washing. These were studied in the first 72 h after injury. A total of 25 children with moderate to severe traumatic brain injury and intraparenchymal ICP monitoring in intensive care (aged 2-17 years) were enrolled. Both ETSMV and LR were associated with clinically and statistically significant changes in ICP from baseline to maximal ICP (p = 0·001 ETSMV; p = < 0·001 LR) and from maximal post-ICP (p = < 0·001 ETSMV; p = < 0.001 LR). Eye care, oral care or washing did not cause any clinically significant change in ICP from baseline. After decompressive craniectomy, none of the interventions caused significant changes in ICP. Only two of the five nursing interventions, endotracheal suctioning and LR, caused intracranial hypertension in moderate to severe traumatic brain-injured children, and after craniectomy, no care interventions caused any significant change in ICP. Knowledge about the physiological effects of many intensive care nursing interventions is lacking and this is magnified in paediatrics. This study provides a significant addition to the evidence base in this area and allows intensive care nurses to plan, implement and evaluate more effectively their nursing care for brain-injured children

A UK and Irish survey of enteral nutrition practices in paediatric intensive care units

The aim of the present study was to describe the present knowledge of healthcare professionals and the practices surrounding enteral feeding in the UK and Irish paediatric intensive care unit (PICU) and propose recommendations for practice and research. A cross-sectional (thirty-four item) survey was sent to all PICU listed in the Paediatric Intensive Care Audit Network (PICANET) database (http://www.picanet.org.uk) in November 2010. The overall PICU response rate was 90 % (27/30 PICU; 108 individual responses in total). The overall breakdown of the professional groups was 59 % nursing staff (most were children's nurses), 27 % medical staff, 13 % dietitians and 1 % physician assistants. Most units (96 %) had some written guidance (although brief and generic) on enteral nutrition (EN); 85 % of staff, across all professional groups (P= 0·672), thought that guidelines helped to improve energy delivery in the PICU. Factors contributing to reduced energy delivery included: fluid-restrictive policies (60 %), the child just being 'too ill' to feed (17 %), surgical post-operative orders (16 %), nursing staff being too slow in starting feeds (7 %), frequent procedures requiring fasting (7 %) and haemodynamic instability (7 %). What constituted an 'acceptable' level of gastric residual volume (GRV) varied markedly across respondents, but GRV featured prominently in the decision to both stop EN and to determine feed tolerance and was similar for all professional groups. There was considerable variation across respondents about which procedures required fasting and the duration of this fasting. The present survey has highlighted the variability of the present enteral feeding practices across the UK and Ireland, particularly with regard to the use of GRV and fasting for procedures. The present study highlights a number of recommendations for both practice and research

An evaluation of enteral feeding practices in critically ill children

Establishing and sustaining enteral feeding in critically ill children is challenging and has met with many problems. The aim of this study was to investigate (a) how actual calorie intake compared with estimated caloric requirements and (b) whether feeding guideline adherence resulted in improved nutritional intake. A prospective observational study was undertaken over 1 month in a tertiary referral paediatric intensive care unit (PICU) in the northwest of England. Forty-seven children were studied, with a wide range of diagnoses in a 1-month period. Only 47% of the children had enteral feeds started within our 6 h post-admission target. Over half (55%) of the children received less than half of their estimated calorie requirements, but if feeding guidelines were followed, this resulted in a significantly higher (p = 0.004) delivery of the child's estimated requirements. This study found that many children are not receiving adequate nutrition in PICU and that the use of feeding guidelines significantly improves calorie delivery in PICU patients. This paper highlights the dearth of research related to enteral feeding in critically ill children. We found that the use of feeding guidelines improved calorie delivery and so units should be encouraged to develop their own guidelines based on the best evidence available

The prognostic ability of early Braden Q Scores in critically ill children

Background: Pressure ulcer (PU) risk assessment tools are an important component of good nursing care; however, it is essential that these tools offer a good sensitivity and specificity, in addition to clinical utility in the population being assessed. Objectives: The aim of this study was to examine how the lowest Braden Q score recorded in the first 24h of paediatric intensive care unit admission related to the risk of PU development in an English PICU (paediatric intensive care unit). Methods: A retrospective cohort study was undertaken over 12months in a single PICU in the North West of England. 891 critically ill children with a Braden Q score were evaluated. The lowest Braden Q score within the first 24h of PICU admission was matched to reported PU development and grade. Results: The Braden Q score was found to perform well in children aged 3weeks to 8years without congenital heart disease (CHD), which is the population it was validated on. At a cut off score of ≤16 it yielded a sensitivity of 100% specificity of 73.1%, positive predictive value (PPV) 2.56 and a negative predictive value (NPV) of 100 and an area under the curve (AUC) of 0.87(0.75-0.98). When used in other age groups and when it included children with CHD, it performed less well with lower AUC and wider confidence intervals, but it performed moderately well in the group of term to 14years with a sensitivity of 75% specificity of 72.6%, PPV 1.5 and a NPV of 99.8 and AUC of 0.74 (0.49-0.98). Conclusion: Our results in a heterogeneous UK PICU population found the Braden Q score performed well in the specific population it was validated for (PICU children aged 3weeks to 8years without CHD), however, it performed moderately well in the more heterogonous PICU population of term to 14years including children with CHD
