Factors associated with place of death for children in South Yorkshire: a retrospective cohort study.

OBJECTIVES: Place of death (POD) is considered a key quality indicator for adult end of-life care, but paediatric evidence is limited. Data from Child Death Overview Panel (CDOP) databases provides an opportunity to describe trends in POD as regional paediatric palliative medicine (PPM) options have increased. Aims were to identify and describe trends in POD for children in South Yorkshire. METHODS: Retrospective cohort study. Anonymised data extracted from five CDOP databases 2008-2015. Data included age, gender, ethnicity, postcode (outward code only), POD, classification and category of death. Descriptive statistical analysis using χ2 test was used to assess intergroup differences. RESULTS: 748 deaths were notified from 2008 to 2015. Neonatal deaths were excluded, 46% (n=345). Of non-neonatal deaths (n=403), 58% (n=232) were 'expected'. Of expected deaths (n=232), 19% (n=45) died in home, 19% (n=45) died in hospice and 61% (n=141) died in hospital. This was significantly different from comparable national data which showed considerably more hospital deaths. There was no significant change in POD over time. CONCLUSION: Hospital remains the POD for most children, whether deaths are 'expected' or not, suggesting specialised PPM should be expanded into the hospital setting. More research is needed regarding preference for POD. This study may help inform future service planning for PPM and hospice development.

Educational impact of paediatric palliative simulation study days.

BACKGROUND: The use of simulation-based medical/nursing teaching is increasingly widespread. Simulation-based teaching offers an immersive learning experience where professionals can practice communication and practical skills in a safe, authentic environment. We designed a paediatric palliative simulation study day primarily aimed at nursing staff who manage these patients in the community/hospice. We believe this is the first of its kind in the UK. AIMS: To establish whether attendance at a paediatric palliative simulation study day improved confidence and knowledge in management of common and/or difficult situations in palliative care. METHOD: Health professionals working at local paediatric hospices or in associated specialties to palliative care were invited to attend the free 1-day course. 5 scenarios were developed by experienced health professionals working in paediatric palliative care. On the day, participants were asked to complete a questionnaire to check basic demographic data, confidence levels and knowledge (50 true/false questions). Following participation/observation of 5 scenarios, they again completed the same questionnaire regarding confidence levels and knowledge. Results were analysed with Excel and XLStat using basic demographic data and Wilcoxon signed rank two-tailed test. RESULTS: 57 healthcare workers participated in 5 study days. 81% (n=47) professionals described themselves as working primarily in palliative care. Only 35% (n=20) had previously experienced simulation. Based on confidence questions, attendees felt more confident in managing specific palliative scenarios (p<0.0001). Based on true/false questions prestudy and poststudy day, 86% (n=49) of participants improved their knowledge. The median improvement score for the cohort was 3 (p<0.0001). CONCLUSIONS: The study demonstrated a significant improvement in confidence and knowledge following the simulation course. This supports further time/financial investment in developing this type of study day. Simulation is a useful teaching adjunct in paediatric palliative care. The course also provides a valuable opportunity for professionals to network and discuss/share experiences.

Paediatric palliative care: intravenous methylnaltrexone relieves constipation.

Methylnaltrexone, a peripheral opioid µ-receptor antagonist is licensed for subcutaneous administration for the treatment of severe opioid-induced constipation in adults. We describe the use of intravenous methylnaltrexone in a 3-year-old boy receiving a subcutaneous diamorphine infusion for palliation from widely metastatic alveolar rhabdomyosarcoma. The patient, who had not opened his bowels for 3 weeks despite use of regular conventional laxatives, was given a 150 mcg/kg dose via indwelling central venous catheter. Constipation was relieved within minutes of the injection. There were no side effects noted during or following injection, and no clinically apparent reduction in analgesia. Intravenous methylnaltrexone may provide a valuable additional treatment option in paediatric palliative care, especially for those with an oncological diagnosis, the majority of whom will have indwelling central venous access devices.

Family involvement in end-of-life care in a paediatric intensive care unit.

End-of-life care (ELC) on a paediatric intensive care unit (PICU) is a fundamental aspect of clinical practice and yet often remains a highly emotive and challenging issue. Every year, many children die in PICU often following the withdrawal of life-sustaining treatment, and as health professionals we have a duty to provide ELC that meets the needs of the dying child and their family. To achieve this, there is a growing emphasis on incorporating parental views on withdrawal of intensive care especially in time and place. Home care of the dying child enables the child to die at home in familiar surroundings and with the people who love them the most. This service is essentially child centred and acknowledges the unique and pivotal position that parents have in their child's life by empowering them to have control over the time and place of death. This is a vitally important aspect of end-of-life in PICU and underpins the ethos of this area of practice. We present a series of case reviews of patients cared for within a 12-month period, where intensive care was withdrawn distant from the PICU environment and address the challenges and considerations surrounding this area of practice.

Consensus guidelines for sustained neuromuscular blockade in critically ill children.

BACKGROUND: The United Kingdom Paediatric Intensive Care Society Sedation, Analgesia and Neuromuscular Blockade Working Group is a multidisciplinary expert panel created to produce consensus guidelines on sedation, analgesia and neuromuscular blockade in critically ill children and forward knowledge in these areas. Neuromuscular blockade is recognized as an important element in the care of the critically ill and adult clinical practice guidelines in this area have been available for several years. However, similar clinical practice guidelines have not previously been produced for the critically ill pediatric patient. METHODS: A modified Delphi technique was employed to allow the Working Group to anonymously consider draft recommendations in up to three Delphi rounds with predetermined levels of agreement. This process was supported by a total of four consensus conferences and once consensus had been achieved, a systematic review of the available literature was carried out. RESULTS: A set of consensus guidelines was produced including six key recommendations. An evaluation of the existing literature supporting these recommendations is provided. CONCLUSIONS: Multidisciplinary consensus guidelines for maintenance neuromuscular blockade in critically ill children (excluding neonates) have been successfully produced and are supported by levels of evidence. The Working Group has highlighted the paucity of high quality evidence in these important clinical areas and this emphasizes the need for further randomized clinical trials in this area.

Continuous venovenous hemofiltration with or without extracorporeal membrane oxygenation in children.

OBJECTIVES: We report the frequency of usage, patient demographics, and outcomes in children treated with continuous venovenous hemofiltration (CVVH) in three pediatric intensive care units (PICUs), with one unit providing combined extracorporeal membrane oxygenation (ECMO) and CVVH. DESIGN: Prospective database analysis. SETTING: Three regional PICUs in the Trent Haemofiltration Network with two general PICUs admitting 450-500 patients annually and the other providing regional cardiac support and a supraregional service for ECMO (600-650 admissions annually with 50 ECMO patients). PATIENTS: Children who underwent CVVH alone or in combination with ECMO or other therapies between January 2000 and December 2002. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: There were 115 children (58 male) treated, with a median age of 18 months (range 1 day to 17 yrs) and median weight of 12 kg (range 1.8-119 kg). In the two PICUs without ECMO, CVVH was undertaken in 2.5% of admissions annually compared with 3% of annual admissions to the PICU with an ECMO service. Fifty-five patients received CVVH alone (group 1), while 53 patients underwent CVVH in conjunction with ECMO (group 2). In addition, five patients received plasmafiltration followed by CVVH, and two patients were treated with combined CVVH and molecular adsorbents recirculating system. Mean duration of therapy in group 1 was 142 hrs (1-840 hrs) and in group 2,231 hrs (3-1104 hrs). Overall patient survival was 43% with 29 of 55 (53%) CVVH patients surviving and 18 of 53 (34%) of those treated with ECMO plus CVVH. CONCLUSIONS: Performing CVVH in a heterogeneous population with large age and weight ranges poses significant clinical and technical challenges. The low frequency of CVVH use, as well as the use of other extracorporeal therapies, also raises problems with maintaining nursing skills. Objective clinical and biochemical markers for commencing CVVH alone or in combination with ECMO remain to be defined.

Consensus guidelines on sedation and analgesia in critically ill children.

OBJECTIVE: The United Kingdom Paediatric Intensive Care Society Sedation, Analgesia and Neuromuscular Blockade Working Group is a multi-disciplinary expert panel created to produce consensus guidelines on sedation and analgesia in critically ill children and forward knowledge in these areas. Sedation and analgesia are recognised as important areas of critical care practice and adult clinical practice guidelines in these fields remain amongst the most popular of those produced by the Society of Critical Care Medicine. However, similar clinical practice guidelines have not previously been produced for the critically ill paediatric patient. DESIGN: A modified Delphi technique was used to allow the Working Group to anonymously consider draft recommendations in three Delphi rounds with predetermined levels of agreement. This process was supported by a total of four consensus conferences. Once consensus had been reached, a systematic review of the available literature was carried out. OUTCOME: A set of consensus guidelines was produced including 20 key recommendations, 10 relating to the provision of analgesia and 10 relating to the sedation of critically ill children. An evaluation of the existing literature supporting these recommendations is provided. CONCLUSIONS: Multi-disciplinary consensus guidelines for maintenance sedation and analgesia in critically ill children have been successfully produced and are supported by levels of evidence (excluding sedation and analgesia for procedures and excluding neonates). The working group has highlighted the paucity of high-quality evidence in these important clinical areas and this emphasises the need for further randomised clinical trials in this area.

Severe lactic acidosis complicating metformin overdose successfully treated with high-volume venovenous hemofiltration and aggressive alkalinization.

OBJECTIVE: In this report of a near-fatal metformin ingestion successfully treated with alkalinization and high-volume hemofiltration, we discuss the management of severe lactic acidosis and demonstrate that early aggressive intervention resulted in a positive outcome. DESIGN: Case report. SETTING: A tertiary pediatric intensive care unit. PATIENT: The patient was a healthy 14-yr-old female found by a sibling following a seizure of unknown duration, thought to be secondary to hypoglycemia as a consequence of a self-ingestion of metformin, atenolol, and diclofenac. She responded well to advanced resuscitation but progressively developed severe lactic acidosis, bradycardia, and hypotension in addition to persistent hypoglycemia. The peak lactate level was 37.5 mmol/L with an albumin corrected anion gap of 65 mmol/L. INTERVENTIONS: She was treated with high-volume venovenous hemofiltration and aggressive alkalinization therapy. The latter facilitated control of severe acidosis, whereas the hemofiltration removed the ingested drugs in addition to endogenously produced lactate precipitated by metformin. CONCLUSIONS: In this case, early and aggressive treatment of the acidosis and cardiovascular compromise with inotropes, venovenous hemofiltration, and large doses of sodium bicarbonate in metformin overdose resulted in a successful outcome even in the presence of severe acidosis and very high lactate levels.

Amylin is associated with delayed gastric emptying in critically ill children.

OBJECTIVES: Amylin is a novel 37 amino acid that is secreted together with insulin from the pancreas in response to enteral nutrient intake. As a potent inhibitor of gastric motility it plays an important role in the control of carbohydrate absorption. In this study we aimed to determine the relationship between amylin levels and gastric emptying in critically ill children. DESIGN: Prospective interventional study. SETTING: Tertiary paediatric intensive care unit. PATIENTS: Twenty-three patients were studied following admission to a paediatric intensive care unit. The median age (25th-75th centiles) was 5.8 years (1.5-11.6) and weight 20 kg (12.8-47.5). INTERVENTIONS: Patients were defined as feed-intolerant on the basis of gastric residual volume greater than 125% 4 h after a feed challenge. Three objective measures of gastric emptying were then calculated from a 6 h paracetamol absorption test. Blood glucose, serum insulin and amylin levels were averaged across the paracetamol absorption test period. MEASUREMENTS AND RESULTS: Eight patients were classified as feed-intolerant (nTOL) and 15 as feed-tolerant (TOL) [median gastric residual volumes 321% (261-495) and 4% (0-6), respectively]. Gastric emptying was delayed in the feed-intolerant group as assessed by all paracetamol absorption test parameters ( p< or =0.01). The median serum amylin concentration was significantly higher in the feed-intolerant group [nTOL 47.0 (37.7-54.8) versus TOL 22.7 (13.6-26.7) pmol/l, p<0.0001]. A positive correlation between serum amylin and insulin was observed ( r=0.46, p=0.02) but not between amylin and glucose ( r=0.25, p=0.23). CONCLUSIONS: The use of gastric residual volumes to define feed intolerance is justified in critically ill children. High serum amylin levels are associated with delayed gastric emptying in these patients. The correlation between serum amylin and insulin levels indicates a degree of preservation of pancreatic hormonal co-release.
