Midazolam versus diazepam para tratamento de estado de mal epiléptico em emergência pediátrica =Midazolam versus diazepam for the treatment of status epilepticus in pediatric emergency
Portela, Janete de Lourdes,Piva, Jefferson Pedro
Scientia Medica , 2011,
Abstract: Objetivos: realizar uma revis o da literatura avaliando o uso de midazolam administrado por diversas vias e do diazepam administrado por via endovenosa e retal no tratamento do estado de mal epiléptico. Fonte de Dados: a pesquisa bibliográfica foi feita nas bases de dados Google Acadêmico, LILACS, PubMed e SciELO, usando os descritores status epilepticus, seizures, benzodiazepines, midazolam, diazepam, children. Síntese dos Dados: o tratamento rápido do estado de mal epiléptico está associado com melhores resultados. Diazepam endovenoso tem sido o tratamento de primeira linha nos últimos 30 anos, apesar da conhecida dificuldade de pun o venosa em crian as pequenas. Midazolam parece representar um avan o importante para o tratamento convulsivo rápido em emergência, pela facilidade de administra o e rapidez de a o. A droga ideal e a via de administra o para o controle das crises nessas situa es permanecem incertas. Conclus es: se o acesso intravenoso n o estiver disponível, há evidências de que o midazolam por via intramuscular, bucal ou nasal pode ser a alternativa ao diazepam endovenoso ou retal, para tratamento de convuls o em emergência pediátrica. Aims: To conduct a review article evaluating midazolam administered by different routes as well as diazepam administered through intravenous and rectal route for treating status epilepticus in children. Source of Data: Bibliographic search was conducted on Google Scholar, LILACS, PubMed and SciELO databases, using the key words status epilepticus, seizure, benzodiazepines, midazolam, diazepam, children. Summary of Findings: Rapid onset treatment of status epilepticus is associated with better results. Diazepam has been the first-line treatment in the last 30 years, despite of known difficulties of venipuncture in infants. Midazolam appears to be an important advance for the quick seizure emergency treatment for its ease administration and rapid action. The ideal drug and route of administration for seizure control in these situations remain uncertain. Conclusions: If intravenous access is not available, there is evidence that intramuscular, oral or nasal midazolam can be an alternative to diazepam (rectal or intravenous) for treatment of seizures in pediatric emergency.
Dexmedetomidine in anesthesia of children submitted to videolaparoscopic appendectomy: a double-blind, randomized and placebo-controlled study
Smania, Maria Cristina;Piva, Jefferson Pedro;Garcia, Pedro Celiny R;
Revista da Associa??o Médica Brasileira , 2008, DOI: 10.1590/S0104-42302008000400015
Abstract: objectives: to evaluate the hemodynamic responses to nociceptive stimuli in children submitted to videolaparoscopic appendectomy under balanced anesthesia with isoflurane and dexmedetomidine. methods: randomized, double-blind and placebo-controlled study involving 26 children submitted to videolaparoscopic appendectomy carried out at hospital s?o lucas (pucrs) between may 2004 and february 2005. patients were assigned to two groups: (a) dexmedetomidine group (n=13): infusion of 1μg/kg over 10 minutes and maintenance dose of 0.5μg/kg/h) as an adjuvant to inhaled isoflurane anesthesia; (b) control group (n=13): normal saline infusion at a similar rate and volume of the dexmedetomidine infusion. during the different surgical and anesthetic periods, groups were compared regarding heart rate, systolic and diastolic arterial blood pressures as well as need of supplemental fentanyl infusion. student's t test, anova, and finner's procedure were used for statistical analysis. results: during the strongest nociceptive stimuli (airway access and abdominal catheter placement), the heart rate and systolic blood pressure increased significantly (p<0.001) in the control group compared to the dexmedetomidine group. compared to baseline levels, the hemodynamic responses to nociceptive stimuli were more stable when dexmedetomidine was used in combination with inhaled isoflurane anesthesia. the need for supplemental doses of fentanyl and the hemodynamic parameters were similar for both groups. conclusion: dexmedetomidine combined with inhaled isoflurane for anesthesia of children submitted to videolaparoscopic appendectomy, efficiently blocks the hemodynamic responses to nociceptive stimuli. when compared to placebo, the use of dexmedetomidine did not change the need for supplemental doses of fentanyl for maintenance of hemodynamic parameters during the intraoperative period.

Gatiboni, Silvia,Piva, Jefferson Pedro,Garcia, Pedro Celiny Ramos
Scientia Medica , 2008,
Abstract: Objetivos: apresentar os tipos de umidificadores mais utilizados em circuitos de ventila o mecanica, principalmente em pacientes pediátricos, e analisar suas vantagens e desvantagens. Fonte de dados: revis o da literatura científica através de artigos pertinentes incluídos na base de dados PubMed/Medline, enfatizando as palavras umidifica o, ventila o mecanica, crian as, umidificadores aquecidos e trocadores de calor e umidade. Também foram incluídos capítulos de livros sobre o assunto. Síntese dos dados: durante a ventila o mecanica, a umidifica o e o aquecimento dos gases inspirados s o necessários para prevenir os efeitos do frio e dos gases secos no epitélio traqueobr nquico. Os dispositivos mais utilizados s o os Umidificadores Aquecidos e os Filtros Trocadores de Calor e Umidade. Conclus es: n o existe consenso quanto ao melhor dispositivo para aquecimento e umidifica o dos gases inspirados, principalmente em pediatria, porém observamos a tendência ao uso de filtros trocadores de calor e umidade, pela facilidade e menor custo. Novas pesquisas s o necessárias para otimizar os filtros trocadores de calor e umidade, diminuindo a resistência e o espa o morto e aumentando a eficácia dos mesmos. Aims: To present the more utilized types of humidifiers in mechanical ventilation circuits, mainly in pediatric patients, and to analyze their advantages and disadvantages. Source of data: Review of the scientific literature through a PubMed/Medline search, emphasizing the words humidification, mechanical ventilation, children, heated humidifiers and heat and moisture exchangers. Also included were book chapters about the subject. Summary of the findings: During mechanical ventilation, humidification and warming of inspired gases are required to prevent the effects of cool and dry gases on the tracheobronquial epithelium. The most used devices are heated humidifiers and heat and moisture exchangers. Conclusions: There are no consensus about the better device to humidification and warming of gases, mainly in pediatrics, but we observed the trend to use the heat and moisture exchangers, because of simplicity and low expense. New research is needed to optimize the heat and moisture exchangers, reducing the resistance and dead-space and increasing their efficacy.
Noradrenalina na terapêutica do choque: recomenda es atuais e novas perspectivas
Alquati, Tamila,Piva, Jefferson Pedro,Garcia, Pedro Celiny Ramos
Scientia Medica , 2008,
Abstract: Objetivos: revisar os principais aspectos do uso de noradrenalina no tratamento do choque, em especial nos pacientes pediátricos. Fonte de dados: revis o bibliográfica no banco de dados MEDLINE, utilizando os termos norepinefrina/ noradrenalina, sepse, choque e uso precoce. Síntese dos dados: a noradrenalina vem sendo utilizada como tratamento adjuvante do choque em pacientes nos quais a resposta à ressuscita o volumétrica n o seja satisfatória. Estudos experimentais da última década apontaram para o uso precoce dessa droga no tratamento do choque, com resultados satisfatórios no que diz respeito à melhor perfus o de órg os e menor necessidade de volume para manter a fun o renal. Conclus es: restam muitas dúvidas acerca da repercuss o clínica do uso precoce de noradrenalina no choque, principalmente na popula o pediátrica. S o necessários mais estudos sobre o assunto, em especial prospectivos e randomizados. Contudo, já há evidências sobre a seguran a do uso dessa droga, que n o aumenta o risco de isquemia renal. Objectives: To review the main aspects of the use of norepinephrine for treatment of shock, especially in children. Source of data: Bibliographic review in the database MEDLINE using the terms norepinephrine, shock, sepsis and early use. Summary of the findings: Norepinephrine has been used as complementary treatment of shock, in patients in whom the response to the volumetric expansion was not satisfactory. Experimental studies from the last decade have encouraged the early use of this drug for shock treatment, with satisfactory results concerning the best perfusion of organs and lesser need of fluids to maintain renal function. Conclusions: Many doubts remain about the clinical utility of the early use of norepinephrine in shock, especially in the pediatric population. More studies are requested, in special prospective and randomized trials. Nevertheless, there is already evidence about the security of the use of norepinephrine, which do not increase the risk of renal ischemia.
Inseguran?a e produ??o de subjetividade no Brasil contemporaneo
Reishoffer, Jefferson Cruz;Bicalho, Pedro Paulo Gastalho de;
Fractal : Revista de Psicologia , 2009, DOI: 10.1590/S1984-02922009000200015
Abstract: the present article aims to put into analysis the subjectification processes that are taking place in contemporary brazil, using as an analytical vector the unsecurity issue. the guattari and rolnik's concept of subjectivity production is used, articulating the context of public insecurity, in the neoliberal order, with the three functions of "capitalistic subjectivity" propounded by the authors: to lay the blame, to segregate and to infantilize. the sensation of insecurity is strengthened by subjectification processes that make the spread of uncertainty the main element of the social control, as well as by the repression of some specific social groups there are seen as "dangerous classes" in a society that works on the consolidation of democracy.

Rotta, Jefferson;Minatti, Edson;Barreto, Pedro Luiz Manique;
Ciência e Tecnologia de Alimentos , 2011, DOI: 10.1590/S0101-20612011000200026
Abstract: in this work, the structural, mechanical, diffractometric, and thermal parameters of chitosan-hydroxypropylmethylcellulose (hpmc) films plasticized with sorbitol were studied. solutions of hpmc (2% w/v) in water and chitosan (2% w/v) in 2% acetic acid solution were prepared. the concentration of sorbitol used was 10% (w/w) to both polymers. this solutions were mixed at different proportions (100/0; 70/30; 50/50; 30/70, and 0/100) of chitosan and hpmc, respectively, and 20 ml was cast in petri dishes for further analysis of dried films. the miscibility of polymers was assessed by x-ray diffraction, scanning electronic microscopy (sem), differential scanning calorimetry (dsc), and thermal gravimetric analysis (tga). the results obtained indicate that the films are not fully miscible at a dry state despite the weak hydrogen bonding between the polymer functional groups.
Psicologia e seguran?a pública: inven??o de outras máquinas de guerra
Bicalho, Pedro Paulo Gastalho de;Kastrup, Virginia;Reishoffer, Jefferson Cruz;
Psicologia & Sociedade , 2012, DOI: 10.1590/S0102-71822012000100007
Abstract: the article discusses the entry of 'professional psy' in the field of public security. for this study we examine key definitions of social control, seeking to link the escalation of insecurity with the advent of the new social order proposed by the neoliberal model, and the reissue of positivist criminology proposals that support policies designed to curb thephenomenon of crime. it also gathers three analyzers, the 'caveir?o', search warrants, and the collective case of resistance, which precipitated a balance of power that strengthens the criminalization of poverty and the adoption of extermination as an official policy of public security. with the prospect of exposing the "make-psychological," puts in question the construction of 'war machines' and the introduction of processes of singularity.
