山东省多中心儿童重症监护室镇静镇痛治疗及管理状况调查

目的了解山东省三级甲等医院儿童重症监护室(PICU)镇静镇痛治疗及管理状况,为镇静镇痛治疗方案的改进提供依据。方法本研究为一项多中心回顾性研究,山东省6家三级甲等医院的PICU参与了本研究。收集2016年1月至2018年12月入住这6家PICU的1340例患儿,调阅病历资料,统计患儿的年龄、性别、入院24 h小儿死亡风险评分Ⅲ、是否接受机械通气、是否接受镇静和(或)镇痛治疗、是否监测镇静和(或)镇痛情况、住院病死率等。依据是否接受镇静治疗和(或)镇痛治疗,将患儿分为单纯镇静组(798例)、镇静+镇痛组(120例)及非镇静镇痛组(422例),比较各组的病种、机械通气比例、低血压发生率、平均住PICU天数及院内病死率。结果1340例患儿的平均年龄为(13.3±6.4)个月,其中男786例(58.7%)。6家PICU均已开展镇静治疗,其中5家PICU进行常规镇静评估;已开展镇痛治疗的PICU有4家,其中仅有2家进行常规疼痛评估。共有918例(68.5%)患儿接受了镇静治疗和(或)镇痛治疗,咪达唑仑是最常用的镇静药物,其次是右美托咪定。526例(57.3%)患儿进行了镇静评估监测,最常用的评估方法是Richmond躁动镇静量表。120例(9.0%)患儿接受了镇静联合镇痛治疗,芬太尼是最常用的镇痛药物,38例(31.7%)患儿接受了常规疼痛评估。3组患儿年龄和性别差异无统计学意义。镇静+镇痛组外科疾病的比例最高,该组机械通气患儿的比例也最高(100.0%,120/120),非镇静镇痛组机械通气患儿的比例最低(11.4%,48/422),两组比较差异有统计学意义(P<0.01)。镇静+镇痛组的平均机械通气时间略短于单纯镇静组,但组间比较差异无统计学意义(P>0.05)。镇静+镇痛组低血压发生率最高,非镇静镇痛组低血压发生率最低[21.7%(26/120)比2.1%(9/422),P<0.01]。院内病死率和平均住PICU天数3组间比较差异无统计学意义。结论苯二氮类药物仍是目前山东省PICU中主要使用的镇静药物,右美托咪定的应用逐渐增加,但镇痛剂应用的比例很低。目前镇痛镇静治疗主要用于外科术后及接受机械通气治疗的患儿,镇痛镇静治疗虽未增加患儿的院内病死率及平均住PICU天数,但增加了低血压的发生率。山东省PICU的镇静镇痛治疗和监测仍欠规范,主要体现在镇痛治疗以及对镇静和疼痛水平的评估未受到重视。     

PICU常用镇痛镇静药物特点及使用方法

在PICU中实施恰当的镇痛镇静可改善患儿的生命质量,避免常见的ICU治疗不良反应.针对每一例患儿均需制定个体化镇痛镇静计划、定期评估镇痛镇静效果并及时调整治疗计划.本文系统介绍了目前我国PICU常用镇痛镇静药物的特点及使用方法,并对一些可能具有应用前景的药物亦作了简单介绍.同时,本文还对镇痛镇静过程中可能出现的不良反应及其预防治疗措施作了系统的阐述.     

Incidence of iatrogenic withdrawal syndrome and associated factors in surgical pediatric intensive care

BackgroundIatrogenic withdrawal syndrome (IWS) is a complication of prolonged sedation/analgesia in pediatric intensive care unit (PICU) patients. The epidemiology of IWS is poorly understood, as validated diagnostic tools are rarely used. The main objective of our study was to use the WAT-1 score to assess the incidence of IWS in our unit. The secondary objectives were to evaluate the consequences of IWS, associated factors, and management modalities.Material and methodsFrom July 2018 to January 2019, 48 children receiving endotracheal ventilation and sedation/analgesia by continuous infusion (>48 h) of benzodiazepines and/or opioids were included. As soon as sedation/analgesia was decreased and until 72 h after its complete discontinuation, the WAT-1 score was determined every 12 h. Substitution therapy was used for 98% of patients upon opioid and/or benzodiazepine withdrawal. IWS was defined as a WAT-1 score ≥3. Factors associated with IWS were assessed by univariate analysis.ResultsIWS occurred in 25 (52%) patients. IWS was associated with a higher number of ventilator-associated pneumonia episodes (17 [68%] vs. one [4%]) and a longer PICU stay (13 [7; 25] vs. 9.0 [5.0; 10.5]) (p<0.001). Overall, 11 patients developed IWS after less than 5 days of sedation/analgesia. Severe head injury was associated with IWS (p = 0.03). Neither sedation discontinuation nor IWS prevention was standardized.ConclusionThe high incidence and adverse consequences of IWS require improved prevention. Risk groups should be defined and a standardized withdrawal protocol established. The occurrence of IWS should be monitored routinely using a validated score.     

Sedation, analgesia, and neuromuscular blockade in the pediatric intensive care unit: survey of fellowship training programs.

OBJECTIVE: To survey current sedation, analgesia, and neuromuscular blockade practices in pediatric critical care fellowship training programs in the United States. DESIGN: Questionnaire survey sent by all program directors. The survey could be submitted either via a Web site, fax, or mail. SETTING: University school of medicine. SUBJECTS: Fifty-nine pediatric critical care fellowship training program directors in the United States, listed on the Accreditation Council for Graduate Medical Education Web site. INTERVENTIONS: Survey. MEASUREMENTS AND MAIN RESULTS: The response rate was 59.3% (35 questionnaires). Midazolam, lorazepam, morphine, and fentanyl are the most frequently used drugs in pediatric intensive care units for analgesia and sedation. Most pediatric intensive care units surveyed have a written sedation policy (66%). The majority of units responding to the survey (85.7%) routinely use a scoring system to assess agitation and pain in children, with the most common being the COMFORT score. All of the pediatric intensive care units surveyed reported weaning drugs slowly to try to prevent drug withdrawal. Movement disorders related to prolonged sedation and analgesia seem to be more common than is reported in the literature, with 65.7% of units reporting cases. There is good consensus on the indications for neuromuscular blockade, with vecuronium being the most popular drug. CONCLUSIONS: When compared with a similar survey from 1989, this survey suggests that pediatric critical care units with fellowship training programs have made some changes in their approach to sedation and analgesia over the past decade. More fellowship directors report the use of sedation protocols and better recognition, prevention, and management of drug withdrawal. Similar analgesic, sedative, and neuromuscular blocking drugs are being used but some more commonly than a decade ago.     

Prevalence and functional status of children with complex chronic conditions in Brazilian PICUs during the COVID-19 pandemic

ObjectiveThe proportion of children with complex chronic conditions is increasing in PICUs around the world. We determined the prevalence and functional status of children with complex chronic conditions in Brazilian PICUs during the COVID-19 pandemic.MethodsThe authors conducted a point prevalence cross-sectional study among fifteen Brazilian PICUs during the COVID-19 pandemic. The authors enrolled all children admitted to the participating PICUs with complex chronic conditions on three different days, four weeks apart, starting on April 4^th, 2020. The authors recorded the patient's characteristics and functional status at admission and discharge days.ResultsDuring the 3 study days from March to June 2020, the authors enrolled 248 patients admitted to the 15 PICUs; 148 had CCC (prevalence of 59.7%). Patients had a median of 1 acute diagnosis and 2 chronic diagnoses. The use of resources/devices was extensive. The main mode of respiratory support was conventional mechanical ventilation. Most patients had a peripherally inserted central catheter (63.1%), followed by a central venous line (52.5%), and 33.3% had gastrostomy or/and tracheostomy. The functional status score was significantly better at discharge compared to admission day due to the respiratory status improvement.ConclusionsThe prevalence of children with CCC admitted to the Brazilian PICUs represented 59.7% of patients during the COVID-19 pandemic. The functional status of these children improved during hospitalization, mainly due to the respiratory component.     

Propofol versus midazolam/ketamine for procedural sedation in pediatric oncology

Different pharmacologic agents have been used for sedation in children undergoing invasive procedures. The authors prospectively compared the efficacy, the occurrence of adverse effects, cardiovascular parameters, oxygen saturation and induction, and recovery time in propofol with or without morphine versus midazolam/ketamine sedation for procedural sedation in children with malignancies and hematologic disorders. Fifty children received either propofol with or without morphine or ketamine/midazolam sedation for invasive procedures. Intravenous sedation consisted of 0.1 mg midazolam/kg and 1.0 mg ketamine/kg or 2 mg propofol/kg with or without 0.1 mg morphine/kg. Incremental dosages of ketamine or propofol were given, if necessary, to achieve or to maintain adequate sedation levels. Systolic and diastolic blood pressure, heart rate, oxygen saturation, time to induce sedation, recovery time, and adverse effects were recorded. All invasive procedures were successfully completed, with satisfactory sedation levels in all 25 patients in the propofol group and 23 of the 25 patients in the ketamine group. In 14 of the 25 procedures in the propofol group and 4 of the 25 procedures in the ketamine group, sedation was associated with side effects, the most common being oxygen desaturation. There was a significant increase in diastolic blood pressure after ketamine medication and a significant decrease in systolic and diastolic blood pressure and heart rate in the propofol group. Induction and recovery times in the propofol group were significantly shorter. Both regimens for procedural sedation are efficacious in achieving satisfactory sedation levels for invasive procedures. Propofol offers a quicker onset of sedation and a faster, smoother recovery but is associated with a higher rate of side effects. Considering the substantial rate of adverse effects, these procedural sedations should be performed only by physicians trained in advanced airway management and life support.     

Recurrence risk after withdrawal of antiepileptic drugs in children with epilepsy: A prospective study

AimTo study recurrence risk after withdrawal of antiepileptic drugs in children with epilepsy.MethodsAll children younger than 14 with two or more unprovoked seizures 24 h apart who were seen at our Hospital between 1994 and 2004 were included consecutively and prospectively followed. Patients previously examined in other centres were excluded. All patients who entered a remission were proposed to stop medication and were followed.ResultsThree hundred and fifty three children with two or more unprovoked seizures were attended. A total of 238 entered a remission period and were proposed to stop medication, 216 accept. Mean seizure-free time before medication withdrawal was 2.2 years. Kaplan-Meier estimate of recurrence risk was 23% at 2 years (95% CI: 17–29) and 28% at 5 years (95% CI: 22–34). A remote symptomatic etiology, various seizure types and a history of prior febrile seizures or prior neonatal seizures were associated with a significant increase in recurrence risk in univariable and multivariable analyses using Cox proportional hazards model. Recurrence risk at 2 years was 17% (95% CI: 11–23) for idiopathic/cryptogenic epilepsies and 41% (85% CI: 28–54) for remote symptomatic epilepsies. Recurrence risks at 2 years by epileptic syndrome were West syndrome (0%), benign rolandic epilepsy (10%), epilepsy without unequivocal partial or generalized seizures (11%), benign infantile seizures (13%), absence epilepsy (16%), cryptogenic partial epilepsies (20%), symptomatic partial epilepsies (45%), symptomatic generalized epilepsies (54%).ConclusionsRecurrence risk after withdrawal of antiepileptic treatment in children is low. Etiology and syndromic diagnosis are the main predictive factors.     

Therapeutic approach to pediatric patients with acute chest syndrome: national multicenter survey of non invasive ventilation (NIV) and transfusion

BackgroundIntensive care units (ICUs) have seen a spike in the use of noninvasive ventilation (NIV) for many medical conditions. We sought to investigate the attitudes and clinical practice regarding the management of acute chest syndrome (ACS) with a focus on NIV in pediatric ICUs.MethodMembers of the French Group for Pediatric Intensive Care Emergencies (GFRUP) were asked to complete an online survey on physicians’ attitudes toward children with ACS admitted to the PICU during 2015.ResultsThe survey was answered by teams from 17 PICUs (240 beds). In total, 15 centers (88%) had a local transfusion unit and 14 (82%) worked in connection with a sickle cell disease (SCD) reference center.During 2015, 360 patients with SCD were managed (median: 7 per center; 21) of whom 137 (38%) for an ACS (median: 4 ACS per center; 8). The median length of PICU stay for ACS was 5 days (3.1).Among the 137 patients who presented with ACS, 73 (53%) received simple blood transfusion and 16 (12%) received exchange transfusion. For patients who required noninvasive ventilatory support, NIV with bilevel pressure (BiPAP) was the most frequent method (n = 68, 50%), followed by continuous positive airway pressure (CPAP) (n = 23, 17%) and high-flow oxygen (n = 21, 15%). The proportion of patients on BiPAP was up to 71% in the centers most frequently managing ACS patients.ConclusionBiPAP is commonly used in PICUs for SCD patients with ACS, especially in trained centers. Future physiological studies and randomized controlled trials might help to choose the best ventilatory support for ACS.     

Pain in neonates: pharmacological treatment]

Pain causes numerous physiological changes in neonates. All invasive procedures induce undesirable stress responses; theses responses can, however, be eliminated or reduced by a judicious use of analgesia. Even though a large number of analgesics and sedatives are currently available, most of them have not been studied in the neonate. At present, a precise understanding of the pharmacological mechanisms of analgesics is difficult because many interactions still remain unknown in the term and premature neonate. This article describes the main analgesics and sedative agents used in the neonate: morphine, fentanyl, sufentanil, alfentanil, nalbuphine, ketamine, midazolam, propofol, acetaminophen, and Emla cream. After a review of the literature regarding these drugs, some practical advices and suggestions for the treatment of procedure-induced pain, and background sedation/analgesia for ventilated neonates are given. It is also stated in this article that the best way to soothe pain in neonates is to combine non pharmacological and pharmacological strategies. At the national level, written guidelines should be prepared in order to improve pain management in the neonate.     

Procedural sedation and analgesia for paediatric patients in the emergency department

Children presenting to the emergency department (ED) often require sedation for brief procedures such as fracture and dislocation reductions, laceration repairs, and imaging procedures that are painful, anxiety provoking or both. This article presents three cases of paediatric patients who require sedation and/or analgesia, and summarizes important aspects of procedural sedation for the primary care practitioner in the emergency setting. Presedation assessment and monitoring equipment are detailed. Discussion of routes of administration and different agents including barbiturates, opiates, benzodiaxepines, the ‘cardiac coctail’, ketamine, propofol, nitrous oxide, and etomidate follow. Emphasis is placed on indications, contraindications, dosing, timing and advantages and disadvantages of each. Reversal agents are mentioned, and discharge criteria are outlined.     

Sedation and analgesia for critically ill children

Effective analgesia and sedation in the paediatric intensive care unit (PICU) encompasses the provision of physical comfort and caring for the psychological well-being of critically ill children. In the UK the most commonly used sedative and analgesic agents for critically ill children are midazolam and either morphine or fentanyl. Consensus clinical practice guidelines for the provision of sedation and analgesia in critically ill children were published in 2006 by the UK Paediatric Intensive Care Society, and an ESPNIC position statement on clinical recommendations for pain, sedation, withdrawal and delirium assessment in critically ill infants and children was published in 2016: Despite this, considerable variation in practice persists. Pain experienced early in life may result in long-term changes in neurosensory function and there are also concerns that sedative and analgesic agents may themselves be associated with developmental neurotoxicity, particularly amongst neonates, and adverse psychological outcomes in survivors of critical care. Validated tools for assessment of withdrawal syndrome and delirium are available and this article will briefly discuss these and how to use them in clinical practice. The most important single factor in reducing avoidable psychological morbidity in survivors of PICU is to minimize the administered doses of sedative and analgesic agents.     

Procedural pain in children: education and management. The approach of an Italian pediatric pain center

Pain management should be warranted for all children in every situation. Italian legislation proposes a model for pain assistance based on specialized tertiary centers which provide direct clinical management for complex cases and assure continuous cooperation with hospitals and family pediatricians for managing painful conditions every day. The Procedural Pain Service of the University of Padua Department of Pediatrics applies such model for procedural pain management. We describe activities of Service since January 1, 2006 on two levels: education and training for territorial services and sedation-analgesia when required for invasive and painful procedures. Since 2006 to date, the Service team produced an internal protocol for procedural sedation, developed two master courses, and organized a training program for procedural pain management in the territorial context. Procedural sedation-analgesia service provided overall 10,832 sedations to perform 14,264 procedures for 3,815 patients, median age of 6 years old. The most frequently performed procedures were lumbar puncture and bone marrow aspiration, followed by gastroscopy and bronchoscopy. Most frequently administered drug combinations were local analgesia + intravenous midazolam alone or midazolam and propofol or midazolam and propofol and ketamine; most frequently used non-pharmacological methods were distraction using cartoons and bubbles. Minor adverse events were recorded in 281 cases (2.5%), the most common being desaturation (2.1%). In conclusion, our model functions on two integrated levels, and it can be considered generally applicable as a solution for pain management.     

Use of Ketofol for procedural sedation and analgesia in children with hematological diseases

Background: The aim of this study was to evaluate the effectiveness and safety of intravenous ketamine–propofol admixture (“ketofol”) in the same syringe for procedural sedation and analgesia in children undergoing bone marrow aspiration. Methods: This was a prospective, observational pilot study. Patients aged between 4 and 12 years requiring sedation for bone marrow aspiration were included. Ketofol (1 : 1 mixture of ketamine 10 mg/mL and propofol 10 mg/mL) was given intravenously in 0.5 mg/kg aliquots each with a 1‐min interval and titrated to reach sedation levels of 3 or 4 (Ramsay score). The primary outcome was patient satisfaction with the degree of sedation. Secondary outcomes included injection pain, total sedation time, recovery time, hemodynamic and respiratory parameters, and adverse events. Results: A total of 20 patients were enrolled in the study. The median total dose of ketofol administered was 1.25 mg/kg each of propofol and ketamine (95%CI 0.77–2 mg/kg). The median score on the visual analog scale was 0 (extremely comfortable) (0–1.5; 95%CI 0.2–2.2). Median recovery time was 23 min (20.5–28 min; 95%CI 17.1–51.2). The incidence of injection pain was 2/20. Two patients had transient diplopia and one child reported dreams. No patients had hypotension, vomiting or required airway intervention. Conclusion: Ketofol provided effective sedation, which was reflected in the high degree of satisfaction recorded by children requiring procedural sedation and analgesia for bone marrow aspiration. We also observed rapid recovery and no clinically significant complications. A large number of patients is required to evaluate and validate these findings.     

Caring for intubated newborns: analgesia and sedation. Collaborative discussions between the Ospedale Pediatrico Bambino Gesú and the Mayo Clinic

Pain relief and sedation are essential for critically ill newborns. Unfortunately, assessment of pain and need for sedation remain difficult. The collaborative discussions in 2007 between the Ospedale Paediatrico Bambino Gesù and the Mayo Clinic provided us with an opportunity to compare and contrast the assessment of pain, assessment of need for sedation and measures used to relieve pain/provide sedation. We began our session with a review of pain assessment tools in newborns and current options for pain relief and sedation. We discussed a pilot audit of analgesia use in the newborn intensive care unit at the Mayo Clinic and the challenges of escalating opiate doses in certain patients. Dr Marina Cuttini from Ospedale Paediatrico Bambino Gesù provided European perspectives. Discussions considered how to improve our bedside nursing assessment of newborn pain. A potential for future collaboration may be to compare analgesia doses for intubated newborns in Rome with doses used in Rochester, either by retrospective chart review or in a prospective study. We might also compare the management of opiate withdrawal in newborns. Research into non-opiate analgesia for newborns may give us new options to avoid opiate side-effects.     

Sedation and analgesia for brief diagnostic and therapeutic procedures in children

The number of diagnostic and therapeutic procedures done outside of the operating room and the intensive care unit has increased substantially in recent years. In parallel, the management of acute pain and anxiety in children undergoing therapeutic and diagnostic procedures has developed considerably in the past two decades. The primary goal of procedural sedation and analgesia is the safe and efficacious control of emotional distress and pain. The availability of non-invasive monitoring, short-acting opioids and sedatives has broadened the possibilities of sedation and analgesia in children in diverse settings. While most of these procedures themselves pose little risk to the child, the administration of sedation or analgesia may add substantial risk to the patient. This article reviews the current status of sedation and analgesia for invasive and non-invasive procedures in children providing an evidence-based approach to several topics of importance, including patient assessment, personnel requirements, equipment, monitoring, and drugs.     

国内28家PICU床旁脑功能监护设备调查

目的：通过对国内28家PICU的床旁脑功能监护设备和使用情况进行调查,了解国内危重病患儿的脑功能监护情况。方法采用问卷调查的方式,对国内28家PICU的床旁脑电监护仪、经颅多普勒超声仪、诱发电位仪、脑部血氧饱和度监护仪、医用控温仪系统和有创颅内压监护仪拥有情况进行调查,对结果进行总结和分析。结果截至2015年9月,22(78.6％)家PICU拥有脑电监护仪,15(53.6％)家PICU拥有经颅多普勒超声仪,5(17.9％)家PICU拥有肌电诱发电位仪,10(35.7％)家PICU拥有脑部血氧饱和度监护仪,25(89.3％)家PICU拥有医用控温仪系统,7(25％)家PICU拥有有创颅内压监测仪。2(7.1％)家 PICU 拥有全部6项设备;3(10.7％)家 PICU 拥有其中5项设备;6(21.4％)家PICU拥有其中4项设备;7(25％)家PICU拥有其中3项设备;3(10.7％)家PICU拥有其中2项设备;6(21.4％)家PICU仅拥有其中1项设备;1(3.6％)家PICU所有设备全无。结论除医用控温仪系统外,其余5项设备在PICU中均配备不足,需进一步推广和普及。     

Propofol Does Not Modify the Hemodynamic Status of Children with Intracardiac Shunts Undergoing Cardiac Catheterization

Immobility and cardiovascular stability are required for cardiac catheterization. Pediatric patients need a type of sedation that also allows spontaneous ventilation without supplemental oxygen. Propofol has been adequate in hemodynamically stable patients with congenital heart disease undergoing cardiac catheterization. However, mild systemic hypotension caused by propofol may increase a preexisting right-to-left shunt. The aim of this study is to evaluate, in pediatric patients scheduled for cardiac catheterization, the effects of propofol on systemic and pulmonic circulations. Fifteen patients aged 18 months to 9 years were studied. After a fast of 4-6 hours for solid food, the patient arrived at the cardiac catheterization suite, where an IV catheter was placed. Usual monitoring was used. For sedation, without supplemental oxygen, patients received 1 mg/kg of fentanyl followed by propofol (1-2 mg/kg) titrated to immobility during preparation of the groin. A continuous infusion of propofol (100 mg/kg/min) was also started to obtain immobility during the procedure. Hemodynamic data, including systemic venous, pulmonary artery and vein, aortic saturations, and pressures, were recorded; Qp and Qs were calculated. The same set of data was re-corded 4 minutes after discontinuation of propofol and when the patient was responding to tactile stimuli. Despite lower pressures during propofol infusion, as compared with those pressures measured after discontinuation of propofol, the extent of the intracardiac shunt remained unchanged. Propofol seems to be an adequate sedative agent for pediatric patients undergoing cardiac catheterization, including those with intracardiac shunts.     

Sedation for pediatric diagnostic imaging: use of pediatric and nursing resources as an alternative to a radiology department sedation team

OBJECTIVE: To develop a pathway to provide safe, effective, and efficient sedation for pediatric diagnostic imaging studies using non-radiology personnel. MATERIALS AND METHODS: A multidisciplinary team considered manpower and training requirements and national sedation standards before designing a sedation pathway, which included scheduling, pre-sedation history and physical, medication protocols, and monitoring. Oral and IV medication protocols were developed based on patient age and weight. Sedation delays were defined as >15 min (IV) or >30 min (PO) from start of sedation to start of imaging. A sedation failure resulted in an incomplete diagnostic imaging study. Failure rates of 124 sedations before and 388 sedations after the pathway were compared. RESULTS: The sedation failure rate for 7 months prior to pathway initiation was 15% (19/124). In the first 25 months after pathway initiation, failures were significantly reduced to 1.5% (6/388) ( P<0.0001). Three (50%) of the six failures after pathway initiation were long examinations (>55 min). Deviation from the recommended medication protocol accounted for most of the 115 delays. Only minor adverse events were seen (12/388, 3.1%). CONCLUSION: Implementing a pediatric sedation pathway significantly decreases the sedation failure rate. Pediatric residents and nurses can safely, effectively and efficiently sedate pediatric patients for routine diagnostic imaging procedures without the need for a radiology department sedation team in a department with a small-to-moderate volume of pediatric patients.
