The frequency of pharmacological pain relief in university neonatal intensive care units

OBJECTIVE: To evaluate the use of drugs to relieve the pain of invasive procedures newborn infants cared for at a university hospital NICU. METHODS: A prospective cohort study of all newborn infants hospitalized in four NICU during October 2001. The following data were collected: demographic data of the hospitalized newborn infants; clinical morbidity; number of potentially painful procedures and frequency of analgesic administration. Factors associated with the use of analgesia in this cohort of patients were studied by multiple linear regression using SPSS 8.0. RESULTS: Ninety-one newborn infants were admitted to the NICU during the study period (1,025 patient-days). Only 25% of the 1,025 patient-days received systemic analgesia. No specific drugs were administered to relieve acute pain during any of the following painful events: arterial punctures, venous, capillary and lumbar punctures or intubations. For chest tube insertion, 100% of newborn infants received specific analgesia. For the insertion of central catheters 8% of the newborn infants received painkillers. Only nine of the 17 newborn infants that underwent surgical procedures received any analgesic dosage during the postoperative period. For 93% of patients under analgesia the drug of choice was fentanyl. The presence of mechanical ventilation increased the chance of newborn infants receiving painkillers by 6.9 times and the presence of chest tube increased this chance by five times. CONCLUSION: It is necessary to train health professionals in order to bridge the gap between scientific knowledge regarding newborn infant pain and clinical practice.OBJETIVO: Verificar a freqüência com que são empregados analgésicos para o alívio da dor desencadeada por procedimentos invasivos em recém-nascidos internados em UTI universitárias e verificar o perfil de uso de medicamentos para o alívio da dor. MÉTODOS: Coorte prospectiva, avaliada entre 1° e 31 de outubro de 2001, de todos os recém-nascidos internados em quatro UTI. Dados coletados: características gerais das unidades; dados demográficos dos recém-nascidos; morbidade clínica e freqüência do emprego de analgésicos. Realizaram-se a análise estatística descritiva e a regressão linear múltipla por meio do SPSS 8.0, para analisar os fatores associados ao uso de analgésicos nesta coorte. RESULTADOS: No período, foram internados 91 recém-nascidos (1.025 pacientes-dia). Apenas 25% dos 1.025 pacientes-dia receberam alguma dose de analgésico por via sistêmica. Não foi administrada nenhuma medicação específica para o alívio da dor aguda durante os seguintes eventos dolorosos: intubações traqueais, punções arteriais, venosas, capilares e lombares. Na inserção de dreno de tórax, 100% dos recém-nascidos receberam analgesia específica e, para a passagem de cateteres centrais, apenas 8%. De 17 recém-nascidos submetidos a procedimentos cirúrgicos, somente nove receberam analgésicos no pós-operatório. O medicamento mais utilizado foi o fentanil (93%). A presença de ventilação mecânica elevou em 6,9 vezes, e a de dreno de tórax em cinco vezes a chance do recém-nascido receber alguma dose de analgésico. CONCLUSÃO: Há necessidade de melhorar a formação dos profissionais de saúde para diminuir a distância entre os conhecimentos científicos existentes a respeito da dor no recém-nascido e a prática clínica.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Disciplina Pediatria NeonatalUniversidade Estadual de Campinas Faculdade de Ciências Médicas Departamento de PediatriaUNICAMP Centro de Atenção Integral à Saúde da MulherUniversidade Estadual Paulista Júlio de Mesquita Filho Faculdade de Medicina Departamento de PediatriaSanta Casa de São Paulo Faculdade de Ciências Médicas Departamento de PediatriaUNIFESP, EPM, Disciplina Pediatria NeonatalSciEL

Sildenafil no tratamento da hipertensão pulmonar após cirurgia cardíaca Sildenafil for pulmonary hypertension treatment after cardiac surgery

OBJETIVO: Relatar o uso do Sildenafil no tratamento da hipertensão pulmonar em recém-nascido após cirurgia cardíaca. DESCRIÇÃO: Recém-nascido de termo, feminino, com diagnóstico de dupla via de saída de ventrículo direito, hipoplasia de pulmonar e comunicação interventricular subaórtica, foi submetido à cirurgia de Blalock na primeira semana de vida. No pós-operatório, evoluiu com hipertensão pulmonar e hipoxemia persistente, não-responsiva ao óxido nítrico, porém com melhora da oxigenação após infusão endovenosa contínua de prostaglandina E1. Depois de várias tentativas malsucedidas de retirada da prostaglandina E1, optou-se pela introdução do Sildenafil via oral. Houve queda da resistência vascular pulmonar, com conseqüente melhora na oxigenação e, 48 horas após, foi possível suspender a infusão de prostaglandina E1. COMENTÁRIOS: O Sildenafil pode ser alternativa terapêutica na hipertensão pulmonar, especialmente quando não houver resposta à terapia convencional.<br>OBJECTIVE: To report on the use of sildenafil for pulmonary hypertension treatment of a newborn patient after cardiac surgery. DESCRIPTION: A female, full term newborn infant with diagnosis of double outlet right ventricle, pulmonary hypoplasia and subaortic ventricular septal defect, was submitted to Blalock surgery in the first week of life. In postoperative the newborn had pulmonary hypertension and persistent hypoxia, without response to nitric oxide, but with improved oxygenation after continuous intravenous infusion of prostaglandin E1. After several failed attempts to discontinue prostaglandin E1, oral sildenafil was used. There was a decrease in pulmonary vascular resistance with consequent oxygenation improvement and 48 hours later it was possible to discontinue prostaglandin E1 infusion. COMMENTS: Sildenafil can be an alternative therapy for pulmonary hypertension, especially when there is no response to conventional therapy

Effects Of Therapeutic Approach On The Neonatal Evolution Of Very Low Birth Weight Infants With Patent Ductus Arteriosus.

To analyze the effects of treatment approach on the outcomes of newborns (birth weight [BW] < 1,000 g) with patent ductus arteriosus (PDA), from the Brazilian Neonatal Research Network (BNRN) on: death, bronchopulmonary dysplasia (BPD), severe intraventricular hemorrhage (IVH III/IV), retinopathy of prematurity requiring surgical (ROPsur), necrotizing enterocolitis requiring surgery (NECsur), and death/BPD. This was a multicentric, cohort study, retrospective data collection, including newborns (BW < 1000 g) with gestational age (GA) < 33 weeks and echocardiographic diagnosis of PDA, from 16 neonatal units of the BNRN from January 1, 2010 to Dec 31, 2011. Newborns who died or were transferred until the third day of life, and those with presence of congenital malformation or infection were excluded. Groups: G1 - conservative approach (without treatment), G2 - pharmacologic (indomethacin or ibuprofen), G3 - surgical ligation (independent of previous treatment). Factors analyzed: antenatal corticosteroid, cesarean section, BW, GA, 5 min. Apgar score < 4, male gender, Score for Neonatal Acute Physiology Perinatal Extension (SNAPPE II), respiratory distress syndrome (RDS), late sepsis (LS), mechanical ventilation (MV), surfactant (< 2 h of life), and time of MV. death, O2 dependence at 36 weeks (BPD36wks), IVH III/IV, ROPsur, NECsur, and death/BPD36wks. Student's t-test, chi-squared test, or Fisher's exact test; Odds ratio (95% CI); logistic binary regression and backward stepwise multiple regression. Software: MedCalc (Medical Calculator) software, version 12.1.4.0. p-values < 0.05 were considered statistically significant. 1,097 newborns were selected and 494 newborns were included: G1 - 187 (37.8%), G2 - 205 (41.5%), and G3 - 102 (20.6%). The highest mortality was observed in G1 (51.3%) and the lowest in G3 (14.7%). The highest frequencies of BPD36wks (70.6%) and ROPsur were observed in G3 (23.5%). The lowest occurrence of death/BPD36wks occurred in G2 (58.0%). Pharmacological (OR 0.29; 95% CI: 0.14-0.62) and conservative (OR 0.34; 95% CI: 0.14-0.79) treatments were protective for the outcome death/BPD36wks. The conservative approach of PDA was associated to high mortality, the surgical approach to the occurrence of BPD36wks and ROPsur, and the pharmacological treatment was protective for the outcome death/BPD36wks

Risk factors for infection with coagulase-negative staphylococci in newborns from the neonatal unit of a brazilian university hospital

Coagulase-negative staphylococci (CoNS) are one of the most frequent causative agents of neonatal nosocomial infections, especially in premature and low-weight newborns. Risk factors for infection include extracellular polysaccharide production and consequent biofilm formation that permit adhesion to the smooth surface of catheters and other medical devices. The objective of this study was to identify CoNS strains isolated from 105 newborns admitted to the Neonatal Unit of our hospital, and to evaluate the association of biofilm production and host risk factors with the occurrence of infection. CoNS isolates were identified and classified as significant or contaminant based on clinical and laboratory data of the newborn medical records. Perinatal risk factors for infection, neonatal clinical evolution, and antibiotic treatment were analysed. In addition, the presence of genes (icaA, icaC and icaD) responsible for biofilm production in CoNS was investigated. Among the 130 CoNS strains studied, 66 (50.8%) were classified as clinically significant and 64 (49.2%) as contaminant. There was no difference in the detection of biofilm-specific genes between CoNS strains isolated from newborns with (81.8%) and without infection (84.3%), although 11 (91.7%) of the 12 children whose death was related to CoNS were infected with strains that were positive for these genes. Forty-five (83.3%) of the 54 newborns infected with CoNS were premature and 33 (61.1%) had a birth weight ≤ 1,500 g. Most newborns infected with CoNS had been submitted to invasive procedures, including catheter use (85.2%), parenteral nutrition (61.1%), and mechanical ventilation (57.4%). S. epidermidis was the most frequently isolated species (81.5%) and was more related to infection (86.3%) than to contamination (76.5%). Most newborns infected with CoNS presented factors that contributed to the colonization and development of infection with these microorganisms, including a birth weight ≤ 1,500 g, catheter complications, use of a drain, and previous antibiotic treatment. The fact that most children who died of CoNS-related infection carried strains positive for biofilm-specific genes indicates the importance of this virulence factor for the outcome of staphylococcal infections
