RESUMO
Resumen: Introducción: Los tumores pulmonares congénitos son patologías poco frecuentes; asimismo, cuando requieren intervención quirúrgica, el médico anestesiólogo se enfrenta a un reto en el manejo de estos pacientes. Presentación del caso: En este artículo describimos el caso y el manejo anestésico de un recién nacido de 37.5 semanas de gestación (SDG) y 26 días de vida extrauterina, programado para toracotomía posterolateral izquierda más lobectomía inferior izquierda y colocación de catéter venoso central bajo anestesia combinada (anestesia general balanceada más bloqueo caudal con bupivacaína y morfina). Conclusiones: Las consideraciones anestésicas para los procedimientos quirúrgicos en neonatos y/o pacientes pediátricos se convierten en un reto para el anestesiólogo, debido a la inmadurez de algunos de los sistemas, se considera que la técnica anestésica idónea para el adecuado manejo de los pacientes neonatales sigue siendo la técnica combinada. El anestesiólogo debe mantener en mente dicha técnica así como los eventos y/o efectos secundarios que se puedan derivar de la misma y de este modo instaurar de manera oportuna el tratamiento pertinente.
Abstract: Introduction: Congenital lung tumors are rare pathologies, likewise when surgical intervention is required, the anesthesiologist faces a challenge in the anesthetic management of these patients. Presentation of the case: The following article describes the case of a 26-day-old newborn child scheduled for left posterolateral thoracotomy plus lower left lobectomy and central venous catheter placement under combined anesthesia (balanced general anesthesia plus caudal block with bupivacaine and morphine). Conclusions: Anesthetic considerations for surgical procedures in neonates and/or pediatric patients become a challenge for the anesthesiologist, due to the immaturity of some of the systems, thus considering that the ideal anesthetic technique for the proper management of in neonatal patients, the combined technique continues, with epidural blocks for the management of peri- and postoperative pain. The anesthesiologist must keep in mind this technique as well as the events and/or side effects that may derive from it, thus establishing the pertinent treatment in a timely manner.
RESUMO
Abstract Background: Surgery generates a neuroendocrine stress response, resulting in undesirable hemodynamic instability, alterations in metabolic response and malfunctioning of the immune system. Objectives: The aim of this research was to determine the effectiveness of caudal blocks in intra- and postoperative pain management and in reducing the stress response in children during the same periods. Methods: This prospective, randomized clinical trial included 60 patients scheduled for elective herniorrhaphy. One group (n = 30) received general anesthesia and the other (n = 30) received general anesthesia with a caudal block. Hemodynamic parameters, drug consumption and pain intensity were measured. Blood samples for serum glucose and cortisol level were taken before anesthesia induction and after awakening the patient. Results: Children who received a caudal block had significantly lower serum glucose (p < 0.01), cortisol concentrations (p < 0.01) and pain scores 3 h (p = 0.002) and 6 h (p = 0.003) after the operation, greater hemodynamic stability and lower drug consumption. Also, there were no side effects or complications identified in that group. Conclusions: The combination of caudal block with general anesthesia is a safe method that leads to less stress, greater hemodynamic stability, lower pain scores and lower consumption of medication.
Resumo Justificativa: O estresse cirúrgico causa resposta neuroendócrina, resultando em instabilidade hemodinâmica indesejável, modificações na resposta metabólica e disfunção no sistema imune. Objetivos: O objetivo deste estudo foi avaliar, em pacientes pediátricos, a eficácia do bloqueio peridural caudal no controle da dor intra e pós-operatória e na redução da resposta ao estresse nesses períodos. Métodos: Estudo clínico prospectivo randomizado que incluiu 60 pacientes submetidos à herniorrafia eletiva. Um grupo (n = 30) recebeu anestesia geral e o outro (n = 30), anestesia geral combinada a bloqueio caudal. Foram medidos os parâmetros hemodinâmicos, o consumo de medicamentos e a intensidade da dor. Amostras de sangue para medir glicemia e cortisol plasmático foram obtidas antes da indução e após o despertar dos pacientes. Resultados: As crianças que receberam bloqueio peridural caudal apresentaram valores significantemente mais baixos para glicemia (p < 0,01), concentração de cortisol (p < 0,01) e escores de dor de 3 horas (p = 0,002) e 6 horas (p = 0,003) após a cirurgia, maior estabilidade hemodinâmica e menor consumo de medicamentos. Além disso, não foram observados efeitos colaterais ou complicações nesse grupo. Conclusões: O bloqueio peridural caudal combinado à anestesia geral é uma técnica segura e que se associa a menor estresse, maior estabilidade hemodinâmica, redução nos escores de dor e baixo consumo de medicamentos.

BACKGROUND: Caudal and penile blocks are the most popular regional anesthetic techniques used in infants and children undergoing urological surgery. A recent report has suggested that penile venous pooling resulting from caudal blocks could affect surgical outcomes after hypospadias operations. OBJECTIVE: The aim was to report our experience in patients with distal hypospadias undergoing repair with caudal versus penile block. STUDY DESIGN: A retrospective clinical database was constructed for patients who underwent distal hypospadias repair by a single surgeon (M.P.B.) at our sponsoring institutions for the time period 2008-2013 (n = 192). Collected data included hypospadias classification (glanular, coronal, subcoronal), chordee status, perioperative anesthesia (caudal vs. penile), and assessment of postoperative complications (fistula and meatal stenosis). RESULTS: Risk ratio (RR) analysis for all distal hypospadias cases revealed that there is a higher risk of developing complications in patients who underwent caudal anesthesia than in patients who underwent penile block RR for a complication was 3.70 (95% CI 1.05-13.03; p < 0.04) (Figure). DISCUSSION: Similar to other papers in the literature, we found that patients who underwent caudal anesthesia had more complications than those who underwent penile block. The limitations of this study include not adjusting the results according to the severity of hypospadias. CONCLUSION: The main goal of this study was accomplished by demonstrating that, in our series, caudal anesthesia is associated with a higher risk of fistula formation after undergoing distal hypospadias repair than penile block.

BACKGROUND AND OBJECTIVES: Emergence agitation is a common postanaesthetic problem in children after sevoflurane anaesthesia. We aimed to compare the effects of ketamine and midazolam administered intravenously, before the end of surgery, for prevention of emergence agitation in children who received caudal block for pain relief under sevoflurane anaesthesia. METHODS: 62 American Society of Anesthesiologists patient classification status I children, aged 2-7 years, scheduled for inguinal hernia repair, circumcision or orchidopexy were enrolled to the study. Anaesthesia was induced with sevoflurane 8% in a mixture of 50% oxygen and nitrous oxide. After achieving adequate depth of anaesthesia, a laryngeal mask was placed and then caudal block was performed with 0.75mLkg(-1), 0.25% bupivacaine. At the end of the surgery, ketamine 0.25mgkg(-1), midazolam 0.03mgkg(-1) and saline were given to ketamine, midazolam and control groups, respectively. Agitation was assessed using Paediatric Anaesthesia Emergence Delirium scale and postoperative pain was evaluated with modified Children's Hospital of Eastern Ontario Pain Scale. RESULTS AND CONCLUSIONS: Modified Children's Hospital of Eastern Ontario Pain Scale scores were found higher in control group than in ketamine and midazolam groups. Paediatric Anaesthesia Emergence Delirium scores were similar between groups. Modified Children's Hospital of Eastern Ontario Pain Scale and Paediatric Anaesthesia Emergence Delirium scores showed a significant decrease by time in all groups during follow-up in postanaesthesia care unit. The present study resulted in satisfactory Paediatric Anaesthesia Emergence Delirium scores which are below 10 in all groups. As a conclusion, neither ketamine nor midazolam added to caudal block under sevoflurane anaesthesia did show further effect on emergence agitation. In addition, pain relief still seems to be the major factor in preventing emergence agitation after sevoflurane anaesthesia.

Justificativa e objetivos: A incidência de agitação é um problema pós-anestésico comum em crianças após a anestesia com sevoflurano. Nosso objetivo foi comparar os efeitos de cetamina e midazolam administrados por via intravenosa, antes do término da cirurgia, para prevenir a incidência de agitação em crianças submetidas ao bloqueio caudal para alívio da dor sob anestesia com sevoflurano. Métodos: Foram inscritos no estudo 62 pacientes pediátricos, entre 2-7 anos, estado físico classificado de acordo com a Sociedade Americana de Anestesiologistas (ASA: I), programados para correção de hérnia inguinal, circuncisão ou orquidopexia. A anestesia foi induzida com sevoflurano a 8% em uma mistura de oxigênio (50%) e óxido nitroso (50%). Depois de atingir a profundidade adequada da anestesia, uma máscara laríngea foi colocada e, em seguida, o bloqueio caudal foi feito com bupivacaína a 0,25% (0,75 mL kg−1). No fim da cirurgia, cetamina (0,25 mg kg−1), midazolam (0,03 mg kg−1) e solução salina foram administrados aos grupos cetamina, midazolam e controle, respectivamente. A incidência de agitaçio foi avaliada com a escala Paediatric Anaesthesia Emergence Delirium (PAED) e a dor no período pós-operatório avaliada com a escala modificada Children's Hospital of Eastern Ontario Pain Scale (mCHEOPS). Resultados e conclusões: Os escores de dor da escala modificada mCHEOPS foram maiores no grupo controle do que nos grupos cetamina e midazolam. Os escores PAED foram semelhantes entre os grupos. Os escores dessas duas escalas mostraram uma diminuição significativa do tempo em todos os grupos durante o acompanhamento em sala de recuperação pós-anestesia. O presente estudo resultou em escores satisfatórios da escala PAED, que ficaram abaixo ...

A sacrum with five pairs of foramina is an anatomical variant resulting from sacralisation of lumbar vertebra at cranial end or sacralisation of coccyx vertebra at caudal end. An unusual gross variation nurtures interest of anatomists and causes concern for clinicians when it mimics pathology. A sacrum with fifth anomalous pair of sacral foramina has been observed which prompted the author to examine the available sacra in the osteology lab of Department of Anatomy KG Medical University Lucknow, UP, India. Of the total sixty six observed sacra, those with five pairs of sacral foramina due to sacralisation of lumbar vertebra were found in eleven cases (16.6%) while those due to sacralisation of coccygeal vertebra were observed in nine cases (13.6%). These sacralisations were classified in five categories to systematise the anatomical study, causes and clinical complications. Sacralisation of lumbar vertebra may compress the fifth sacral nerve causing sciatica and back pain. It may also cause herniation of disc above sacralisation. Sacralisation of coccygeal vertebra may influence the caudal block anaesthesia in surgical procedures and also results in prolonged second stage of labor and perineal tears.
Un sacro con cinco pares de forámenes es una variante anatómica que resulta de la sacralización de la vértebra lumbar al extremo craneal o sacralización de la vértebra coxis al extremo caudal. Esta variación inusual es de interés para los anatomistas como también motivo de preocupación para los médicos al asemejar una patología. Un sacro con un quinto par anómalo de forámenes fue observado, por lo que se examinaron otros sacros del laboratorio de osteología del Departamento de Anatomía Médica de la Universidad de Lucknow, India. De un total de 66 sacros estudiados, en 11 casos (16,6%) se observaron cinco pares de forámenes sacros, debido a la sacralización de la vértebra lumbar; mientras que en 9 casos (13,6%), se observó la sacralización de la vértebra caudal. Estos fueron clasificados en cinco categorías para sistematizar el estudio anatómico, sus causas y complicaciones clínicas. La sacralización de la vértebra lumbar puede comprimir el quinto nervio, causando ciática sacra y dolor de espalda. También puede causar una hernia discal superior a la sacralización. La sacralización de la vértebra caudal, puede influir en la anestesia de bloqueo caudal en procedimientos quirúrgicos y también dar lugar a una prolongada etapa del trabajo de parto y desgarros perineales.
