Premedication for neonatal endotracheal intubation: results from the epidemiology of procedural pain in neonates study.

OBJECTIVES: To describe the frequency and nature of premedications used prior to neonatal endotracheal intubation; to confront observed practice with current recommendations; and to identify risk factors for the absence of premedication. DESIGN, SETTING, AND PATIENTS: Data concerning intubations were collected prospectively at the bedside as part of an observational study collecting around-the-clock data on all painful or stressful procedures performed in neonates during the first 14 days of their admission to 13 tertiary care units in the region of Paris, France, between 2005 and 2006. INTERVENTION: Observational study. MEASUREMENTS AND MAIN RESULTS: Specific premedication prior to endotracheal intubation was assessed. Ninety one intubations carried out on the same number of patients were analyzed. The specific premedication rate was 56% and included mostly opioids (67%) and midazolam (53%). Compared with recent guidance from the American Academy of Pediatrics, used premedications could be classified as "preferred" (12%), "acceptable" (18%), "not recommended" (27%), and "not described" (43%). In univariate analysis, infants without a specific premedication compared with others were younger at the time of intubation (median age: 0.7 vs. 2.0 days), displayed significantly more frequent spontaneous breathing at the time of intubation (31% vs. 12%) and a higher percentage of analgesia for all other painful procedures (median values: 16% vs. 6%). In multivariate analysis, no factor remained statistically significant. CONCLUSIONS: Premedication use prior to neonatal intubation was not systematically used and when used it was most frequently inconsistent with recent recommendations. No patient- or center-related independent risk factor for the absence of premedication was identified in this study.

Epidemiology and treatment of painful procedures in neonates in intensive care units.

CONTEXT: Effective strategies to improve pain management in neonates require a clear understanding of the epidemiology and management of procedural pain. OBJECTIVE: To report epidemiological data on neonatal pain collected from a geographically defined region, based on direct bedside observation of neonates. DESIGN, SETTING, AND PATIENTS: Between September 2005 and January 2006, data on all painful and stressful procedures and corresponding analgesic therapy from the first 14 days of admission were prospectively collected within a 6-week period from 430 neonates admitted to tertiary care centers in the Paris region of France (11.3 millions inhabitants) for the Epidemiology of Procedural Pain in Neonates (EPIPPAIN) study. MAIN OUTCOME MEASURE: Number of procedures considered painful or stressful by health personnel and corresponding analgesic therapy. RESULTS: The mean (SD) gestational age and intensive care unit stay were 33.0 (4.6) weeks and 8.4 (4.6) calendar days, respectively. Neonates experienced 60,969 first-attempt procedures, with 42,413 (69.6%) painful and 18,556 (30.4%) stressful procedures; 11,546 supplemental attempts were performed during procedures including 10,366 (89.8%) for painful and 1180 (10.2%) for stressful procedures. Each neonate experienced a median of 115 (range, 4-613) procedures during the study period and 16 (range, 0-62) procedures per day of hospitalization. Of these, each neonate experienced a median of 75 (range, 3-364) painful procedures during the study period and 10 (range, 0-51) painful procedures per day of hospitalization. Of the 42,413 painful procedures, 2.1% were performed with pharmacological-only therapy; 18.2% with nonpharmacological-only interventions, 20.8% with pharmacological, nonpharmacological, or both types of therapy; and 79.2% without specific analgesia, and 34.2% were performed while the neonate was receiving concurrent analgesic or anesthetic infusions for other reasons. Prematurity, category of procedure, parental presence, surgery, daytime, and day of procedure after the first day of admission were associated with greater use of specific preprocedural analgesia, whereas mechanical ventilation, noninvasive ventilation and administration of nonspecific concurrent analgesia were associated with lower use of specific preprocedural analgesia. CONCLUSION: During neonatal intensive care in the Paris region, large numbers of painful and stressful procedures were performed, the majority of which were not accompanied by analgesia.

Epidemiologic investigation of Burkholderia cepacia acquisition in two pediatric intensive care units.

OBJECTIVES: To investigate and describe an outbreak of Burkholderia cepacia in a neonatal intensive care unit (NICU) and a pediatric intensive care unit (PICU), and to report the interventions leading to the cessation of the outbreak. DESIGN: We conducted an epidemiologic investigation of an outbreak of B. cepacia colonization or infection in two clinical wards during a 35-month period (December 1998 to October 2001). SETTING: A 500-bed, university hospital-affiliated, tertiary-care pediatric institution in Paris, France, with a 22-bed PICU and 31-bed NICU. METHODS: Ribotyping was used to determine the genotypes of B. cepacia isolates. Procedures for the maintenance and disinfection of respiratory therapy devices were reviewed. RESULTS: Thirty-two children were colonized (n = 14) or infected (n = 18) by B. cepacia in 2 wards (28 in the PICU and 4 in the NICU). In the PICU, a single ribotype was found among the isolates obtained from all of the patients except 1, and from the 6 isolates obtained from respiratory therapy devices (ie, heated humidifier water). In the NICU, the isolates obtained from the patients harbored a single ribotype unrelated to that of the epidemic strain isolated in the PICU; no environmental source of infection was found. CONCLUSION: Two different outbreaks appeared to be associated with 2 ribotypes, 1 of which was linked to patient-to-patient transmission via respiratory therapy devices. Complete elimination of the outbreak was achieved only when disposable, sterilizable, or easy-to-disinfect materials were used in the PICU. The source of infection in the NICU was not found.

Whole-body cooling after perinatal asphyxia: a pilot study in term neonates.

In order to test the practicability and safety of whole-body cooling in term neonates with moderate-to-severe hypoxic-ischaemic encephalopathy (HIE) and to report outcomes, a prospective pilot study was carried out in 25 term infants (median postmenstrual age 38 weeks, range 36 to 41 weeks; 20 males, five females). Whole-body cooling, to a target core temperature of 33 to 34 degrees C, started within 6 hours of birth and was maintained for 72 hours. Of the 25 newborn infants (19 Sarnat II and six Sarnat III, 18 outborn), 18 survived, including 13 (72%) with normal cerebral signal by MRI. Temperature instability occurred during cooling in 15 infants, but neither severe haemodynamic instability nor renal failure was seen. Thrombocytopenia developed in 12 infants, including seven with biological disseminated intravascular coagulation. One patient had hypoxaemia with right-to-left shunting through the ductus arteriosus, and seven had limited meningeal or subdural bleeding. Whole-body cooling is feasible in term neonates, with no life-threatening adverse events. Improvements are needed to obtain stable hypothermia for 72 hours.

Separate-lung ventilation strategy for reimplantation of esophageal bronchus.

IMPLICATIONS: We describe an original ventilation method designed to optimize lung recruitment and gas exchanges during surgery in a newborn with congenital esophageal atresia and ectopic esophageal implantation of the left mainstem bronchus. This strategy ensured constant adaptation of the mechanical ventilatory regimen to the surgical procedure-linked constraints.

Amniotic fluid inflammatory proteins and digestive compounds profile in fetuses with gastroschisis undergoing amnioexchange.

OBJECTIVE: In gastroschisis, an inflammatory process related to the presence of digestive compounds may be involved in intestinal damage. We measured the amniotic fluid concentrations of total protein, ferritin and amylase, lipase, gamma-glutamyl transferase and bile acids before each amnioexchange performed in women whose infants had gastroschisis. We estimated the correlation among total proteins, ferritin and digestive compounds and postnatal outcome. DESIGN: All women whose infants had gastroschisis in our fetal medicine unit are offered repeated amnioexchange during the third trimester of pregnancy to improve the quality of the exteriorised bowel at birth. Amniotic fluid was sampled at the beginning of each amnioexchange and total proteins, ferritin and digestive compounds were assayed. SETTING: This study was conducted in the Department of Perinatology of the University Hospital Robert Debré in Paris. POPULATION: Thirty pregnant women with a gastroschisis affected fetus diagnosed antenatally. METHODS: The biological results were expressed as multiples of the median with respect to a control population. MAIN OUTCOME MEASURE: Gestational age at delivery and the outcome of the infants were recorded and correlated with amniotic fluid total proteins, ferritin and digestive compounds. RESULTS: There was a positive correlation (P < 0.01) between digestive compounds (except amylase at the final amnioexchange) and ferritin on the one hand, and all digestive compounds and total proteins concentration at the final amnioexchange on the other. In addition, among total proteins amylase and lipase, lipase concentrations were related with parameters of short term outcome (P < 0.05). CONCLUSION: Amniotic total proteins and ferritin are elevated in fetuses presenting with gastroschisis as a consequence of an inflammatory process. Inflammation may be induced by the presence of digestive compounds in the amniotic fluid. The concentrations of which may constitute a marker of short term outcome of the newborn infant.
