Nurse-driven pediatric analgesia and sedation protocol reduces withdrawal symptoms in critically ill medical pediatric patients.

BACKGROUND: While several analgesia and sedation guidelines and protocols have been developed and implemented for adults, there is still little evidence of clinical use of analgesia and sedation protocols and the impact on withdrawal symptoms in critically ill children. OBJECTIVE: The aim of this study was to evaluate the effects of a nurse-driven goal-directed analgesia and sedation protocol for mechanically ventilated pediatric patients (pASP) on duration of mechanical ventilation, pediatric intensive care unit (PICU) length of stay, total doses of opioids and benzodiazepines, and occurrence of withdrawal symptoms. PATIENTS AND METHODS: This is a before and after protocol implementation study in a 14-bed medical-surgical-cardiac pediatric intensive care unit at a university children's hospital. A total of 337 medical pediatric patients requiring mechanical ventilation with PICU length of stay for at least 24 h were included. Prior to implementation of the protocol, analgesia and sedation was managed by the attending physician's order. Afterwards, postimplementation, nurses managed analgesia and sedation following a pASP, including COMFORT 'behavioral' Scale, Nurse Interpretation Sedation Scale, and Sophia Observation Withdrawal Symptoms Scale. RESULTS: One hundred and sixty-five patients were included in the 15-month period before and 172 patients were included in the 15-month period after implementation of the pASP. Median duration of mechanical ventilation was 2.02 (0.96-25.0) days in the group preceding protocol implementation and 1.71 (0.96-66.0) days afterwards (P = 0.23). Median PICU length of stay was 5.8 (1-37.75) days in the preimplementation and 5.0 (1-120) days in the postimplementation group (P = 0.14). Total doses of opioids and benzodiazepines were 3.9 mg·kg(-1) ·day(-1) (0.1-70) vs 3.1 mg·kg(-1) ·day(-1) (0.05-56); P = 0.38 and 5.9 mg·kg(-1) ·day(-1) (0-82.0) vs 4.2 mg·kg(-1) ·day(-1) (0-66); P = 0.009 after implementation. Incidence of withdrawal was significantly lower over the postimplementation period (12.8% vs 23.6%; P = 0.005). CONCLUSION: Implementation of a nurse-driven pASP reduced the total dose of benzodiazepines and the occurrence of withdrawal symptoms significantly.

Analysis of sternotomy as treatment option for the resection of bilateral pulmonary metastases in pediatric solid tumors.

BACKGROUND: Radical surgical resection of metastases is an important prognostic factor for survival of patients suffering from solid pediatric tumors. The aim of this study is to evaluate the efficacy of median sternotomy as treatment option for the resection of multiple bilateral lung metastases in children with different tumor entities. Furthermore, the sensitivity of preoperative imaging (CT) was assessed by intraoperative findings. PATIENTS AND METHODS: Between 2002 and 2007, 13 children (4 with sarcoma, 4 with nephroblastoma, 5 with hepatoblastoma) underwent median sternotomy for resection of bilateral lung metastases after R0-resection of the primary tumor. In 6/13 cases, the sternotomy was combined with the primary tumor resection. RESULTS: Median patient age at the first operation was 5 years (range: 11 months to 17 years). The median total number of resected metastases per operation was 9 and ranged from 0 to 65. In 13/16 operations, the intraoperative number of metastases did not agree with the preoperative radiological work-up. Median hospital stay was 14 days (range from 9 to 36 days). Ten out of 13 children are alive after a median follow-up of 13 months (range from 6 to 66 months). CONCLUSION: Median sternotomy is an adequate treatment modality for the resection of bilateral pulmonary metastases as a one-stage procedure. The combination of primary tumor resection with sternotomy should be considered as a treatment option. Complete resection of metastases of solid pediatric tumors should be aimed for in order to increase the survival of these patients.

Insulin tolerance test causes hypokalaemia and can provoke cardiac arrhythmias.

We report the observation and analysis of a new adverse event during the insulin tolerance test (ITT) and propose additional safety procedures. An 8-year-old girl with growth hormone insufficiency had a cardiac arrest due to ventricular flutter when she was tested for growth hormone deficiency by the ITT. Severe hypokalaemia (K+ 2.6 mmol/l) was observed after resuscitation. Ergometry ECG revealed catecholaminergic polymorphic ventricular tachycardia, a hereditary arrhythmogenic disease. Consecutive measurements of serum potassium during ITT in 29 short children (21 boys) with growth failure revealed a mean decrease of serum potassium by 1.1 +/- 0.4 mmol/l with the nadir at 30 min after the insulin bolus. Hypokalaemia (serum potassium < 3.5 mmol/l) occurred in all but one child; severe hypokalaemia (serum potassium < 2.9 mmol/l) was measured in every third child. This observation indicates that acute hypokalaemia which is induced by insulin and catecholamine excess occurs frequently in ITT. The case shows that the combination of acute hypokalaemia and the adrenergic counterregulation in ITT is a strong trigger of cardiac arrhythmias, which can become life-threatening if the child has an arrhythmogenic disease. Therefore, we recommend ECG monitoring during ITT to enhance the detection of cardiac arrhythmias. In addition, in the case of a comatose child during ITT the determination of the glucose and potassium level as well as adequate treatment are necessary.

Risks of mortality in children admitted to the paediatric intensive care unit after haematopoietic stem cell transplantation.

The risk of mortality in children admitted to the paediatric intensive care unit (PICU) after haematopoietic stem cell transplantation is felt to be very high. Life-threatening complications leading to PICU admission are due to organ toxicity caused by conditioning regimes and graft-versus-host disease (GVHD), systemic infections and other organ dysfunctions. Data collected between October 1998 and December 2001 of paediatric patients undergoing haematopoietic stem cell transplantation and thereafter admitted to the PICU were retrospectively analysed in order to reveal the possible causes and risk factors related to death while in the PICU. Twenty-six PICU admissions were recorded. We found a mortality rate of 57.7% and a 6-month survival rate of 23.1%. Univariate analysis identified an oncological paediatric risk of mortality (O-PRISM) score above 10 points, sustained renal failure and a failed negative fluid balance as significant predictors to non-survival.

Molecular diagnostics facilitate distinction between lethal and non-lethal subtypes of junctional epidermolysis bullosa: a case report and review of the literature.

UNLABELLED: The term epidermolysis bullosa (EB) encompasses a heterogeneous group of genodermatoses, characterised by fragility and blistering of the skin, often associated with extracutaneous manifestations. The clinical picture comprises severe subtypes with lethal outcome in the first years of life as well as milder subtypes with localised blistering or minimal symptoms confined exclusively to nail or teeth abnormalities. We present the case of a male infant, who was born with a few bullae and rapidly developed extensive blistering of the skin. The disease was complicated by painful erosions of the oral mucosa, refused ingestion, and recurrent infections. The child died at the age of 4 months because of cardiac failure due to severe sepsis. Antigen mapping of a skin biopsy showed a split within the lamina lucida of the epidermal basement membrane zone and junctional epidermolysis bullosa (JEB) was diagnosed within the first 3 weeks of life. Markedly reduced staining for laminin 5 indicated the Herlitz type of JEB (OMIM 226700), which could be confirmed by mutation analysis in the LAMB3 gene, showing homozygous nonsense mutations. CONCLUSION: early antigen mapping using antibodies against the proteins affected in epidermolysis bullosa, is a useful tool providing early mutation analysis and valuable prognostic information needed for adequate therapeutic strategies. The recently published literature on current diagnostic procedures and the revised classification system for inherited epidermolysis bullosa aim towards a better understanding of the disease.
