Ética no processo ensino-aprendizagem em enfermagem obstétrica

O estudo objetivou evidenciar ética e solidariedade no processo de ensinar-cuidar da mulher no pré-natal e parto. Adotou-se estudo de caso centrado na pedagogia crítica-reflexiva. Foram entrevistados 39 alunos do curso de Enfermagem da Universidade Federal do Ceará e seis docentes que ministraram aulas teórico-práticas. Os resultados mostraram que alunos e professores têm consciência da necessidade da competência ética e sua aplicabilidade no cuidar e que há necessidade de novas estratégias de ensino para o aluno desenvolver ações interativas, humanas e solidárias. O cuidar carece de metodologias atualizadas que envolvam a mulher como participante do processo e possibilitem o respeito à sua dignidade.

Conceitos de enfermeiros e médicos de um serviço de emergência sobre dor e analgesia no trauma

Analisaram-se os conceitos sobre dor e analgesia no trauma de enfermeiros e médicos de um serviço de emergência. Foram realizadas entrevistas semi-estruturadas com 100% da equipe de enfermeiros (22) e 85% da equipe médica (22) do Pronto-Socorro Cirúrgico do HCFMUSP. A análise dos dados apontou alguns conceitos concordantes e outros discordantes com a literatura. Os profissionais estavam de acordo na maior parte dos conceitos, mas diferiram em alguns. Na opinião dos profissionais, baixa prioridade é dada ao controle da dor no trauma.

Centro de parto normal e a assistência obstétrica centrada nas necessidades da parturiente

Levando em conta os vários estudos e reflexões a respeito do novo modelo de assistência ao parto e nascimento (assistência humanizada), e trabalhando como enfermeira obstétrica em um Centro de Parto Normal, surgiu o questionamento a respeito desse conceito, devido às diversas conotações dadas a esse termo. Este artigo foi produzido com a finalidade de divulgar nossa proposta de substituição da expressão "assistência humanizada ao parto", por "assistência obstétrica centrada nas necessidades da parturiente", e de discorrer como essa assistência é prestada no Centro de Parto Normal do Hospital Geral de Itapecerica da Serra (SP), que segue um protocolo de condutas obstétricas e normas preconizadas pelo Ministério da Saúde.

Relação entre a gravidade do trauma e padrões de analgesia utilizados em acidentados de transporte

Trata-se de um estudo inédito realizado no país, que identificou relações entre o padrão analgésico e a gravidade do trauma. Para tal, analisou-se uma população de 200 acidentados de transporte admitidos para tratamento na unidade de emergência de um hospital referência para o atendimento ao trauma no Município de São Paulo. A gravidade das lesões e do trauma foi caracterizada por índices de gravidade anatômicos. A partir da análise da terapia analgésica encontrada, construíram-se padrões de analgesia, tendo como base a escala analgésica da Organização Mundial de Saúde. Os resultados permitiram identificar associação estatística entre a gravidade do trauma e padrões distintos de analgesia. Espera-se que a divulgação desses achados possa servir de base para a criação de protocolos de analgesia em trauma e melhoria da qualidade da assistência, além de servir de estímulo para o desenvolvimento de estudos em uma área com tantas lacunas de conhecimento em nosso meio.

Crioterapia no pós-parto: tempo de aplicação e mudanças na temperatura perineal

Estudo descritivo com dados de dois ensaios clínicos realizados em 2008 e 2009 em uma maternidade de uma instituição filantrópica da cidade de São Paulo. Teve como objetivo descrever a temperatura perineal após a aplicação de bolsa de gelo no pós-parto normal. Três grupos com 38 puérperas cada (n=114) receberam aplicação perineal de bolsa de gelo entre 2 e 48h após o parto. Os achados indicaram que com 10 min de crioterapia as médias da temperatura perineal atingiram de 13,3 a 15,3oC, com pequena redução de temperatura ao final de aplicações de 15 e 20 minutos (2,4 e 2,7o, respectivamente). Após resfriamento por 10 min., as mulheres referiram frio e alívio e, depois de 15 a 20 min., dormência e anestesia local. Conclui-se que 10 minutos de aplicação foram suficientes para reduzir a temperatura perineal aos níveis recomendados para analgesia (10-15oC).

Analgesia e sedação durante a instalação do cateter central de inserção periférica em neonatos

Objetivou-se caracterizar as estratégias de analgesia e sedação em neonatos submetidos à instalação do cateter central de inserção periférica (CCIP) e relacioná-las ao número de punções venosas, duração do procedimento e posicionamento da ponta do cateter. Estudo transversal com coleta prospectiva de dados, realizado em uma unidade de cuidados intensivos neonatais de um hospital privado na cidade de São Paulo, no período de 31 de agosto de 2010 a 01 de julho de 2011, em que foram avaliadas 254 inserções do CCIP. A adoção de estratégias analgésicas ou sedativas ocorreu em 88 (34,6%) instalações do cateter e não esteve relacionada ao número de punções venosas, duração do procedimento ou posicionamento da ponta do cateter. As estratégias mais frequentes foram a administração endovenosa de midazolam em 47 (18,5%) e fentanil em 19 (7,3%) inserções do cateter. Recomenda-se maior adoção de estratégias analgésicas antes, durante e após o procedimento.

Direct cost of connecting, maintaining and disconnecting patient-controlled analgesia pump

Quantitative research that aimed to identify the mean total cost (MTC) of connecting, maintaining and disconnecting patient-controlled analgesia pump (PCA) in the management of pain. The non-probabilistic sample corresponded to the observation of 81 procedures in 17 units of the Central Institute of the Clinics Hospital, Faculty of Medicine, University of Sao Paulo. We calculated the MTC multiplying by the time spent by nurses at a unit cost of direct labor, adding the cost of materials and medications/solutions. The MTC of connecting was R$ 107.91; maintenance R$ 110.55 and disconnecting R$ 4.94. The results found will subsidize discussions about the need to transfer money from the Unified Health System to hospitals units that perform this technique of analgesic therapy and it will contribute to the cost management aimed at making efficient and effective decision-making in the allocation of available resources.

Patients's satisfaction concerning postoperative analgesia after caesarean section: a comparison of 4 alternative analgesic regimen

Introduction: Different routes of postoperative analgesia may be used after cesarean section: systemic, spinal or epidural [1]. Although the efficacy of these alternative analgesic regimen has already been studied [2, 3], very few studies have compared patients' satisfaction between them. Methodology: After ethical committee acceptation, 100 ASA 1 patients scheduled for an elective cesarean section were randomized in 4 groups. After a standardized spinal anesthesia (hyperbaric bupivacaine 10 mg and fentanyl 20 μg), each group had a different postoperative analgesic regimen: - Group 1: oral paracetamol 4x1 g/24 h, oral ibuprofene 3x600 mg/24 h and subcutaneous morphine on need (0.1 mg/kg 6x/24 h) - Group 2: intrathecal morphine (100 μg) and then same as Group 1 - Group 3: oral paracetamol 4x1 g/24 h, oral ibuprofene 3x600 mg/24 h and PCEA with fentanyl 5 μg/ml epidural solution - Group 4: oral paracetamol 4x1g/24 h, oral ibuprofene 3x600 mg/ 24 h and PCEA with bupivacaine 0.1% and fentanyl 2 μg/ml epidural solution After 48 hours, a specific satisfaction questionnaire was given to all patients which permitted to obtain 2 different scores concerning postoperative analgesia: a global satisfaction score (0-10) and a detailed satisfaction score (5 questions scored 0-10 with a summative score of 0-50). Both scores, expressed as mean ± SD, were compared between the 4 groups with a Kruskall-Wallis test and between each group with a Mann-Whitney test. A P-value <0.05 was considered significant. Results: Satisfaction scores Gr. 1 (n = 25) Gr. 2 (n = 25) Gr. 3 (n = 25) Gr. 4 (n = 25) P-value global (0-10) 8.2 ± 1.2 9.0 ± 1.0 7.8 ± 2.1 6.5 ± 2.5 0.0006 detailed (0-50) 40 ± 6 43 ± 5 38 ± 6 34 ± 8 0.0002 Conclusion: Satisfaction scores were significantly better in patients who received a systemic postoperative analgesia only (Groups 1 and 2) compared to patients who received systemic and epidural postoperative analgesia (Groups 3 and 4). The best scores were achieved with the combination of intrathecal morphine and multimodal systemic analgesia (Group 2) which allowed early ambulation without significant pain. Patients treated with postoperative epidural analgesia with combined local anesthetics and opioids (Group 4) obtained the worse scores (more restrictive nursing with less mobility, frequent asymmetrical block with insufficient analgesia on one side and motor block on the other)

Influence of CYP2D6 activity on pre-emptive analgesia by the N-methyl-D-aspartate antagonist dextromethorphan in a randomized controlled trial of acute pain.

BACKGROUND: There is some evidence that dextromethorphan (DM) is effective as a pre-emptive analgesic agent.  DM is mainly metabolized to dextrorphan (DOR) by CYP2D6 whose activity can be inhibited by pharmacologic intervention. OBJECTIVES: To investigate the efficacy of DM as a pre-emptive analgesic agent and describe the population pharmacokinetics in the presence of normal and poor CYP2D6 metabolism in acute post-operative pain. STUDY DESIGN: Double blind, randomized, placebo-controlled trial SETTING: Post-surgical analgesic consumption after knee ligament surgery, a setting of acute pain. METHODS: Forty patients were randomized to a single oral dose of 50 mg quinidine or placebo, administered 12 hours before 50 mg DM. Patients were genotyped for the major CYP2D6 and ABCB1 variants and phenotyped for CYP2D6 using urine DM/DOR metabolic ratios and blood samples for population pharmacokinetic modeling. RESULTS: Quinidine was effective in inhibiting CYP2D6 activity, with 2-fold reduction of DM to DOR biotransformation clearance, prolonged DM half-life, and increased DM systemic availability. Patients in the quinidine group required significantly less often NSAIDs than patients in the placebo group (35.3% vs. 75.0%, P = 0.022). The odds ratio for NSAID consumption in the placebo vs. quinidine group was 5.5 (95% confidence interval (CI) 1.3 - 22.7) at 48 hours after surgery. LIMITATIONS: While this study shows an impact of DM on pre-emptive analgesia and is mechanistically interesting, the findings need to be confirmed in larger trials. CONCLUSION: CYP2D6 inhibition by quinidine influenced the pre-emptive analgesic effectiveness of DM confirming that CYP2D6 phenotypic switch increases the neuromodulatory effect of oral dextromethorphan.

Efecto de la hidratación endovenosa con Hidroxietil almidón 6% (Voluven®) versus Ringer Lactato previa a la analgesia epidural en la incidencia de hipotensión durante el trabajo de parto

En pacientes gestantes durante trabajo de parto, la fluidoterapia endovenosa es fundamental en la prevención de la hipotensión tras la analgesia epidural y mantener el bienestar materno-fetal. El tipo de fluidoterapia administrada (coloides o cristaloides) puede influir en la incidencia y grado de dicha hipotensión. El objetivo de nuestro estudio fue evaluar la incidencia de hipotensión tras la administración de un coloide (Hidroxietil almidón 6%, 250 ml) o un cristaloide (Ringer Lactato 750 ml), evaluando también la posible repercusión fetal. Hasta la fecha hemos incluido 60 gestantes, mostrando una tendencia a una mejor hemodinámica en el grupo coloides

Sedation and analgesia for colonoscopy: patient tolerance, pain, and cardiorespiratory parameters.

BACKGROUND: Colonoscopy is generally performed with the patient sedated and receiving analgesics. However, the benefit of the most often used combination of intravenous midazolam and pethidine on patient tolerance and pain and its cardiorespiratory risk have not been fully defined. METHODS: In this double-blind prospective study, 150 outpatients undergoing routine colonoscopy were randomly assigned to receive either (1) low-dose midazolam (35 micrograms/kg) and pethidine (700 micrograms/kg in 48 patients, 500 micrograms/kg in 102 patients), (2) midazolam and placebo pethidine, or (3) pethidine and placebo midazolam. RESULTS: Tolerance (visual analog scale, 0 to 100 points: 0 = excellent; 100 = unbearable) did not improve significantly more in group 1 compared with group 2 (7 points; 95% confidence interval [-2-17]) and group 3 (2 points; 95% confidence interval [-7-12]). Similarly, pain was not significantly improved in group 1 as compared with the other groups. Male gender (p < 0.001) and shorter duration of the procedure (p = 0.004), but not amnesia, were associated with better patient tolerance and less pain. Patient satisfaction was similar in all groups. Oxygen desaturation and hypotension occurred in 33% and 11%, respectively, with a similar frequency in all three groups. CONCLUSIONS: In this study, the combination of low-dose midazolam and pethidine does not improve patient tolerance and lessen pain during colonoscopy as compared with either drug given alone. When applying low-dose midazolam, oxygen desaturation and hypotension do not occur more often after combined use of both drugs. For the individual patient, sedation and analgesia should be based on the endoscopist's clinical judgement.

Effects of epidural analgesia on pelvic floor function after spontaneous delivery : a longitudinal retrospective study

Abstract: The aim of the study was to assess the effects of epidural analgesia on pelvic floor function. Eighty- two primiparous women (group 1, consisting of 41 given an epidural, and group 2 of 41 not given an epidural) were investigated during pregnancy and at 2 and 10 months after delivery by a questionnaire, clinical examination, and assessment of bladder neck behavior, urethral sphincter function and intravaginal/intra-anal pressures. The prevalence of stress urinary incontinence was similar in both groups at 2 months (24% vs. 17%, P = 0.6) and 10 months (22% vs. 7%, P = 0.1), as was the prevalence of decreased sexual vaginal response at 10 months (27% vs. 10%, P= 0.08). Bladder neck behavior, urethral sphincter function and intravaginal and intra-anal pressures showed no significant differences between the two groups. Ten months after spontaneous delivery, there were no significant differences in the prevalence of stress urinary incontinence and decreased sexual vaginal response, or in bladder neck behavior, urethral sphincter function and pelvic floor muscle strength between women who had or had not had epidural analgesia.

Intrathecal analgesia and restrictive perioperative fluid management within enhanced recovery pathway: hemodynamic implications.

BACKGROUND: Intrathecal analgesia and avoidance of perioperative fluid overload are key items within enhanced recovery pathways. Potential side effects include hypotension and renal dysfunction. STUDY DESIGN: From January 2010 until May 2010, all patients undergoing colorectal surgery within enhanced recovery pathways were included in this retrospective cohort study and were analyzed by intrathecal analgesia (IT) vs none (noIT). Primary outcomes measures were systolic and diastolic blood pressure, mean arterial pressure, and heart rate for 48 hours after surgery. Renal function was assessed by urine output and creatinine values. RESULTS: One hundred and sixty-three consecutive colorectal patients (127 IT and 36 noIT) were included in the analysis. Both patient groups showed low blood pressure values within the first 4 to 12 hours and a steady increase thereafter before return to baseline values after about 24 hours. Systolic and diastolic blood pressure and mean arterial pressure were significantly lower until 16 hours after surgery in patients having IT compared with the noIT group. Low urine output (<0.5 mL/kg/h) was reported in 11% vs 29% (IT vs noIT; p = 0.010) intraoperatively, 20% vs 11% (p = 0.387), 33% vs 22% (p = 0.304), and 31% vs 21% (p = 0.478) for postanesthesia care unit and postoperative days 1 and 2, respectively. Only 3 of 127 (2.4%) IT and 1 of 36 (2.8%) noIT patients had a transitory creatinine increase >50%; no patients required dialysis. CONCLUSIONS: Postoperative hypotension affects approximately 10% of patients within an enhanced recovery pathway and is slightly more pronounced in patients with IT. Hemodynamic depression persists for <20 hours after surgery; it has no measurable negative impact and therefore cannot justify detrimental postoperative fluid overload.
