Bloqueo interescalénico en el contexto de la recuperación acelerada para artroscopía de hombro: serie de casos / Interscalene block in the context of enhanced recovery for shoulder: A case series

Introducción La aplicación de la recuperación acelerada en cirugía de hombro no ha tenido una aceptación tan favorable. Por ello, el objetivo de este estudio fue presentar y describir el uso de bloqueo interescalénico para favorecer la recuperación acelerada en una serie de pacientes sometidos a cirugía artroscopica de hombro. Métodos Se incluyeron 35 pacientes sometidos a cirugía artroscópica de hombro, en quienes se administró bloqueo interescalénico y sedación. Posteriormente se evaluó la intensidad del dolor, náuseas, vómito, disnea, presencia de síndrome de Horner, visión borrosa, ronquera, tiempo transcurrido hasta el alta, reingresos no planeados, satisfacción del paciente y cumplimiento de los criterios de alta hospitalaria en las primeras 12 horas siguiendo los criterios de una recuperación acelerada. Resultados En total, 27 pacientes (77,1%) tuvieron clasificación de la (ASA) I y 8 pacientes (22,9%) ASA II. Además, 97,1% fueron reparaciones de manguito rotador. Previo al alta, dos pacientes (5,7%) presentaron náuseas. Al momento del alta ningún paciente presentó disnea o visión borrosa, dos pacientes (5,7%) presentaron ronquera y la mediana de intensidad del dolor fue de 1,0 (0,0 a 7,0). Entre las 24 y 48 horas solo un (2,8%) paciente presentó náuseas y la mediana de intensidad del dolor fue de 1,0 (0,0 a 8,0). Todos los pacientes se mostraron satisfechos con disposición a repetir la experiencia. El 100% de pacientes cumplió los criterios médicos de alta a las 12 horas y 30 pacientes (85,7%) se dieron de alta el mismo día. La estancia fue de 12 (11,5 a 12,5) horas y ningún paciente reingresó. Conclusión En pacientes seleccionados, con un equipo quirúrgico-anestésico comprometido, capacitado y con experiencia, hay una alta posibilidad de que el bloqueo interescalénico favorezca la realización de programas de recuperación acelerada en cirugía artroscópica de hombro.

Introduction The application of enhanced recovery in shoulder surgery has not had such a favorable acceptance, therefore, the objective of this study was to present and describe the use of interscalene block to promote enhanced recovery in a series of patients undergoing shoulder arthroscopic surgery. Methods Thirty-five patients undergoing arthroscopic shoulder surgery were included, in whom interscalene blockade and sedation were administered. Subsequently, pain intensity, nausea, vomiting, dyspnea, presence of Horner's syndrome, blurred vision, hoarseness, time elapsed to discharge, unplanned readmissions, patient satisfaction, and compliance with hospital discharge criteria in the first 12 weeks were evaluated, hours following the criteria of an enhanced recovery. Results 27 patients (77,1%) had ASA I and 8 patients (22,8%) ASA II, 97,1% were rotator cuff repairs. Before discharge, two patients (5.7%) had nausea. At discharge, no patient had dyspnea or blurred vision, two patients (5.7%) developed hoarseness, and the median pain intensity was 1.0 (0.0-7.0). Between 24 and 48 hours only one patient (2.8%) presented nausea and the median pain intensity was 1.0 (0.0-8.0). All the patients were satisfied with their willingness to repeat the experience, 100% of the patients met the criteria for medical discharge after 12 hours, 30 patients (85.7%) were discharged the same day, the stay was 12 (11.5 to 12.5) hours, and no patient was readmitted. Conclusion In selected patients with a committed, trained and experienced surgical-anesthetic team, there is a high possibility that the interscalene block will favor the performance of enhanced recovery programs in shoulder arthroscopic surgery.

Siete años de experiencia en pacientes intervenidos por patología proctológica bajo modalidad cirugía mayor ambulatoria y estudio del grado de satisfacción usuaria

Objetivo: Exponer los resultados de 7 años de cirugía proctológica por cirugía mayor ambulatoria (CMA) y determinar el grado de satisfacción usuaria. Material y Método: Se realizó un estudio observacional descriptivo de pacientes sometidos a cirugía proctológica bajo modalidad CMA en el Hospital Regional de Concepción entre los años 2012 y 2019. Se realizó la encuesta telefónica de satisfacción SUCMA-14. Resultados: Se evaluaron a 632 pacientes en el período de estudio. Con diferencias estadísticamente significativas entre patologías para edad, género e IMC. Se aplicó la encuesta a 270 pacientes que contestaron y respondieron. Los resultados mostraron que en general la percepción de los pacientes es positiva salvo puntuales excepciones, como el dolor postoperatorio para condilomas y hemorroides, y las complicaciones postoperatorias para la enfermedad pilonidal. Cuando se realiza el análisis multivariado a los datos correspondientes a la encuesta, no se logran diferencias significativas entre los diagnósticos, pero al aplicarlo a las variables clínico-quirúrgicas se evidencia, claramente, que existe una distinción entre éstas, en especial para la enfermedad pilonidal. Discusión: Las diferencias en términos de tiempos quirúrgicos, complicaciones y re-hospitalizaciones, no necesariamente afectan la percepción que los pacientes tienen de la CMA, ya que ésta depende de otros factores y no solo de los resultados quirúrgicos. Conclusión: Se obtuvieron resultados acorde a la literatura internacional, con peores resultados para enfermedad pilonidal. La satisfacción usuaria fue positiva en general, sin una clara distinción por patologías. Creemos que la CMA es recomendable en patología proctológica tanto por sus resultados, como por la satisfacción que genera en los pacientes.

Objective: To present the results of 7 years of colorectal surgery on mayor ambulatory surgery (MAS) and to determine patient satisfaction. Methods: A descriptive observational study of patients undergoing proctological surgery under the MAS modality was carried out at Regional Hospital of Concepción between 2012 and 2019. The SUCMA-14 satisfaction survey was applied. Results: 632 patients were evaluated in the study period. With statistically significant differences between pathologies for age, gender and BMI. The survey was applied to 270 patients who answered and responded. The results showed that, in general, the perception of the patients is positive, with exceptions, such as postoperative pain for warts and hemorrhoids, and postoperative complications for pilonidal disease. When the multivariate analysis corresponding to the survey is performed, it does not allow distinguishing between the diagnoses, but when applied to the surgical variables, it clearly shows that there is a distinction between them, with a disadvantage for pilonidal disease. Discussion: The differences in terms of surgical times, complications and re-hospitalizations do not necessarily affect the perception that patients have of the MAS, since it depends on other factors and not only on the surgical results. Conclusion: Results were concordant to what is described in the international literature, with worse results for pilonidal disease. Patient satisfaction was positive in general, without a clear distinction by pathology. We believe that MAS is recommended in proctological pathology both for its results and for the satisfaction it generates in patients.

Enxertos compostos de gordura para correção de distrofia facial em caso de esclerodermia localizada / Composite fat grafts for correcting facial dystrophy in a case of localized scleroderma

A esclerodermia localizada (morfeia linear) é uma doença rara que causa distrofia e assimetria faciais em mulheres jovens. É relatado o caso de uma paciente de 20 anos que foi tratada com enxertos compostos de gordura. Após a coleta do lipoaspirado de gordura subcutânea profunda, a microgordura e a nanogordura não filtrada foram processadas separadamente para formar enxertos compostos de gordura. Estes foram meticulosamente transplantados em camadas, para reconstruir o subcutaneo da face da paciente. Após um ano, observou-se boa pega de gordura com correção bem-sucedida da assimetria e restabelecimento do equilíbrio facial.

Localized scleroderma (linear morphea) is a rare disease that causes facial dystrophy and asymmetry in young women. We report the case of a 20-year-old female patient who was treated with novel composite fat grafts. After extracting lipoaspirate from deep subcutaneous fat, the microfat and the unfiltered nanofat were processed separately, and amalgamated, obtaining composite fat grafts. These were meticulously transplanted layer by layer to rebuild the subcutaneous tissue of the patient's face. After one year, a good volume of fat retention was observed with successful correction of asymmetry and restoration of facial balance.

Impact of the covid-19 pandemic on the surgical treatment of spine pathologies in sus / Impacto da pandemia da covid-19 no tratamento cirúrgico de patologias de coluna no sus / Impacto de la pandemia de covid-19 en el tratamiento quirúrgico de patologías de la columnavertebral enel sus

ABSTRACT Objective: To evaluate the impact of the COVID-19 pandemic on spine surgeries performed by SUS. To identify changes in surgical volume, as well as which procedures and regions of Brazil were most affected. To correlate such changes with literature data. Methods: A retrospective, descriptive study was conductedwith an analysis of the databases available to the public on the performance of spinal surgical procedures by SUS during the period from 2017 to 2021. The databases were created from variables of interest available in the SIH (Hospital Information System) of the SUS Information Technology Department website (DATASUS; http://datasus.saude.gov.br). The procedures were grouped according to type of surgery, topography, and access route for the construction of tables and statistical analysis. Results: In the years of the pandemic, a greater drop in surgical volume was observed, with a total of 13,276 procedures in 2020 and 12,158 in 2021, equivalent to -28.51% and -34.53%, respectively, of the average of the previous period. Conclusions: Given the paramount importance of attention to the fight against the pandemic, maintaining the level of assistance for spinal pathologies proved to be a great challenge, especially in relation to elective surgical pathologies that, when delayed too much, can seriously impact the quality of life and outcomes of future treatments. Level of Evidence: IV; Retrospective, descriptive.

Virtual Reality as a distraction therapy during cystoscopy: a clinical trial / A Realidade Virtual como terapia de distração durante cistoscopias: um ensaio clínico

ABSTRACT Objectives: to investigate whether virtual reality (VR) experience is associated with decreased pain sensation among patients who undergo rigid cystoscopy under local anesthesia. Methods: we performed a prospective, randomized, controlled study of 159 patients who were aleatorily enrolled into two groups: VR and control. VR experience intervention consisted of using a headset with a smartphone adapted to a virtual reality glasses where an app-video was played during the procedure. Main outcomes analyzed were pain, discomfort, heart rate variability, difficulty and duration of the cystoscopy. Statistical analyses were performed using a Student's t test, Mann-Whitney test and Chi-square test. A P<0.05 was considered to be statistically significant. Results: among 159 patients studied (VR group=80 patients; control group=79 patients), the mean age was 63,6 years and 107 (67,3%) were male. There was no statistically significant difference in baseline characteristics between the 2 groups. VR was significantly associated to decreased heart rate variability (6,29 vs 11,09 bpm, P<0,001) and lower duration of the procedure (5,33 vs 8,65 min, P<0,001). Also, when cystoscopies due to double-J extraction were excluded, VR experience was associated with reduced pain on the visual analog score of pain (3,26 vs 4,33 cm, P=0,023). Conclusions: the use of VR as a distraction therapy while performing outpatient cystoscopies is safe, has no side effects, is associated with less pain and discomfort, and reduces length of procedure.

RESUMO Objetivos: investigar se a experiência de realidade virtual (RV) está associada à diminuição da dor em pacientes submetidos à cistoscopia rígida sob anestesia local. Métodos: foi realizado um estudo prospectivo, randomizado e controlado de 159 pacientes que foram alocados aleatoriamente em dois grupos: RV e controle. A intervenção da experiência de RV consistiu no uso de óculos de realidade virtual com smartphone adaptado e fones de ouvido, onde um vídeo foi reproduzido durante o procedimento. Os principais desfechos analisados foram dor, desconforto, variabilidade da frequência cardíaca, dificuldade e duração da cistoscopia. As análises estatísticas foram realizadas com o teste t de Student, o teste de Mann-Whitney e o teste do qui-quadrado. Um P<0,05 foi considerado como estatisticamente significativo. Resultados: entre os 159 pacientes estudados (grupo RV=80; grupo controle=79), a média de idade foi 63,6 anos e 107 (67,3%) eram do sexo masculino. Não houve diferença estatisticamente significativa nas características basais entre os grupos. A RV foi significativamente associada à menor variabilidade da frequência cardíaca (6,29 vs 11,09 bpm, P<0,001) e menor duração do procedimento (5,33 vs 8,65 min, P<0,001). Além disso, quando cistoscopias devido à extração de duplo J foram excluídas, a RV foi associada à redução da dor na escala visual analógica (3,26 vs 4,33cm, P=0,023). Conclusões: o uso da RV como terapia de distração durante a realização de cistoscopias ambulatoriais é seguro, não tem efeitos colaterais, está associado a menos dor e desconforto e reduz a duração do procedimento.

Analgesic modalities for ambulatory laparoscopic cholecystectomy / 中华普通外科杂志

Objective:To explore the analgesic methods in ambulatory laparoscopic cholecystectomy (LC) patients.Methods:Three hundred patients were randomly divided into six groups receiving different analgesic regimen. VAS scores, postoperative blood pressure, CRP, IL-6, and the occurrence of postoperative adverse effects were recorded at 2, 4, 8, and 12 h postoperatively.Results:The success rate of ambulatory LC in this study was 66.22%. The dynamic VAS scores of patients in each group gradually decreased with time elapsing, with groups B and C being significantly lower than group A at 2 h and 4 h postoperatively ( P<0.05). Groups D, E and F were significantly different from group A at all postoperative time points ( P<0.05). There was a statistically significant difference at 8 h and 12 h postoperatively in group B vs. group D and group C vs. group E (all P<0.05). There was significant difference at the 12 h postoperatively between groups (B and C) compared to group F ( P<0.05). There was a significant difference in CRP and IL-6 between the groups (all P<0.05). Postoperative dizziness, nausea and delayed discharge were significantly higher in patients using analgesic pumps ( P<0.05). Conclusion:Local infiltration of ropivacaine combined with postoperative parecoxib sodium drip is a recommended analgesic regimen.

Efficacy of remimazolam combined with propofol for sedation in pediatric patients undergoing outpatient dental root canal treatment / 中华麻醉学杂志

Objective:To evaluate the effect of remimazolam combined with propofol for sedation in the pediatric patients undergoing outpatient root canal treatment.Methods:Seventy pediatric patients of either sex, aged 2-6 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, with an expected treatment time<1 h, scheduled for elective outpatient root canal treatment, were divided into 2 groups ( n=35 each) using a random number table method: propofol group (P group) and remimazolam plus propofol group (RP group). Induction of anesthesia was as follows: propofol 1-3 mg/kg was intravenously injected until BIS value was less than 60 in group P, and remimazolam 0.2 mg/kg and propofol 1-3 mg/kg were intravenously injected until BIS value was less than 60 in group RP.Anesthesia maintenance was as follows: propofol 6-12 mg·kg -1·h -1 was intravenously infused in group P, and remimazolam 0.3 mg·kg -1·h -1 and propofol 6-12 mg·kg -1·h -1 were intravenously infused in group RP.The BIS value was maintained at 50-70 during operation.Spontaneous breathing was kept, and oxygen was inhaled through a nasal catheter with oxygen flow rate of 2-3 L/min in both groups.The amount of propofol consumed during induction and maintenance periods and the total consumption were recorded.The onset time of sedation, duration of operation, emergence time and duration of post-anesthesia care unit stay were recorded.The adverse reactions such as intraoperative respiratory depression, hypotension, bradycardia, coughing and body movement, emergence agitation and postoperative nausea and vomiting were recorded. Results:Compared with group P, the amount of propofol consumed during induction and maintenance periods and the total consumption were significantly reduced, the onset time of sedation was prolonged, the emergence time and duration of post-anesthesia care unit stay were shorted, the incidence of respiratory depression was decreased ( P<0.05), and no significant change was found in the incidence of duration of operation, hypotension, bradycardia, body movement or emergence agitation in group RP ( P>0.05). No intraoperative coughing or postoperative nausea and vomiting was found in two groups. Conclusions:The combination of remimazolam and propofol provides better efficacy than propofol alone when used for sedation in the pediatric patients undergoing outpatient dental root canal treatment.

Short-term clinical outcomes of outpatient total hip arthroplasty / 中华骨科杂志

Objective:To investigate the safety, economic effect, and short-term clinical efficacy of ambulatory total hip arthroplasty (THA) in the treatment of hip osteopathy within.Methods:This study retrospectively reviewed patients who underwent 48-hour outpatient THA and conventional primary THA from July 2020 to July 2021. Gender, age, body mass index (BMI), clinical diagnosis, place of resident, length of hospital stay, duration of the surgery, hemoglobin, albumin, C-reactive protein (CRP) and D-dimer before and 1 day after surgery, the visual analogue scale (VAS) was obtained postoperative day 2, hip joint modified Harris score before and 1 month after surgery, readmission and reoperation within 1 month after operation as the data of evaluations were extracted and compared in this study.Results:A totally of 150 cases were involved in this study, which including 75 cases with 48-hour outpatient primary THA and 75 cases with conventional primary THA. There was no significant difference between the two groups in terms of age, sex, BMI, education level, preoperative diagnosis, and preoperative Harris score ( P>0.05), but a significant difference was found in term of residence (χ 2=6.29, P=0.043), that the patients in the outpatient group were all from Zhejiang Province and 48% (36/75) of them were from Hangzhou City. While, in the conventional group, 6 patients were from other provinces. The length of stay was 2.13±0.52 days and operation time was 59.73±18.91 minutes in the outpatient group, which were both shorter than those (6.71±1.44 days and 66.91±22.40 min) in the conventional group ( t=25.91, P<0.001 for the length of hospital stay; t=2.12, P=0.036 for operation time). Compared with the conventional group, outpatient group saved the average hospital cost (4.60±0.44 vs. 5.20±0.72 ten thousand yuan, t=6.16, P<0.001). The VAS on the second day after surgery 3.45±0.75 was higher in the outpatient group than in the conventional group (3.45±0.75 vs. 3.16±0.94 points, t=2.09, P=0.039). The modified Harris score was without statistical significance ( t=0.42, P=0.677) 1 month after surgery in both groups. 75 patients in the outpatient group, 7 patients delayed discharge (were not discharge within 48 hours), and the rate of delayed discharge was 9.3%. Reasons for delayed discharge included poor pain control in two cases, one case had postoperative nausea and vomiting, one case had failed to meet rehabilitation standards, hypotension in one case, the intraoperative infection in one case and postoperative fever within 48 hours in one case. Conclusion:Outpatient THA can reduce the length of hospital stay, operative time and total cost of hospitalization. It has similar safety and early clinical efficacy as conventional THA. However, a small proportion of patients would delay discharge.

Planejamento e marcação simplificados de mastopexia e mamoplastia redutora: o padrão circunvertical "Matryoshka" / Simplified planning and marking of mastopexy and reduction mammoplasty: the circumvertical "Matryoshka" pattern

■ RESUMO Introdução: Como a maioria dos outros procedimentos estéticos, particularmente em órgãos pareados para os quais a simetria é crítica, o resultado bem-sucedido da mastopexia e mamoplastia redutora é amplamente determinado pelo planejamento pré-operatório. Ao considerar cuidadosamente o desenho da ressecção da pele e escolher e desenhar um pedículo apropriado, a necrose da pele, cicatrizes inestéticas e distorção da forma podem ser minimizadas. Métodos: Apresentamos uma técnica original de marcação de pele que combina as vantagens do uso de um template Wise como base para marcação de pele com aquelas do padrão de mamoplastia vertical junto com uma excisão periareolar limitada de pele para encurtar a cicatriz vertical subareolar. Resultados: O design de marcação circunvertical da pele que propomos imita a silhueta de uma boneca russa, a "Matryoshka". Conclusão: Incorporar uma marcação pré-operatória mensurável e com base geométrica certamente oferece um grande grau de controle e consistência.

■ ABSTRACT Introduction: Like most other aesthetic procedures, particularly in paired organs for which symmetry is critical, the successful outcome of mastopexy and reduction mammoplasty is greatly determined by pre-operative planning. By carefully considering the design of the skin resection and choosing and designing an appropriate pedicle, prevention of skin necrosis, unsightly scars, and shape distortion can be minimized. Methods: We present an original skin marking technique that combines the advantages of using a Wise template as the basis for skin marking with those of the vertical mammoplasty pattern together with a limited circumareolar skin excision to shorten the subareolar vertical scar. Results: The circumvertical skin marking design we propose mimics a Russian doll silhouette, the "Matryoshka." Conclusion: Incorporating a geometrically based and measurable pre-operative marking certainly offers a great degree of control and consistency.

Cirugía de mano con anestesia local con técnica WALANT. Experiencia con una serie de casos / Hand surgery with local anesthesia with WALANT technique. Experience with a cases series

Resumen Introducción: Los procedimientos en cirugía de mano requieren el uso de torniquete para evitar el sangrado y, generalmente, utilizan sedación por anestesiología para controlar el dolor e incomodidad del torniquete. Hace una década se viene usando en cirugía de mano anestesia local sin torniquete ni sedación, como una opción segura y eficiente para las intervenciones quirúrgicas; esta técnica es conocida como WALANT (en inglés). El objetivo del trabajo es evaluar una serie prospectiva de pacientes intervenidos con técnica de WALANT en cirugía de mano. Métodos: Es una serie de casos que caracteriza el desempeño de una técnica anestésica local para procedimientos en cirugía de mano sin sedación y sin torniquete. Se evaluaron tiempo de cirugía, dolor intra- y posoperatorio y nivel de satisfacción. Este trabajo es aceptado por el comité de ética. Resultados: Se operaron 96 pacientes, 73 fueron cirugías de partes blandas y 23 de partes óseas. 92 pacientes (96 %) refirieron estar satisfechos y sin dolor posoperatorio. En 4 casos fue necesaria sedación intraoperatoria. Ningún paciente requirió torniquete. No fue necesario usar volúmenes mayores a 40 ml, sin embargo, estos varían según el tipo de intervención. Conclusiones: Este estudio muestra que la técnica funciona muy bien, y es de gran utilidad en cirugías de tendones, donde se requiere que el paciente esté despierto para evaluar el funcionamiento intraoperatorio. Los costos de cirugía son más baratos y es una técnica reproducible, con un desempeño satisfactorio.

Abstract Introduction: Procedures in hand surgery require tourniquet use to control bleeding and generally sedation by anesthesiology to manage the pain and discomfort of the tourniquet. A decade ago, local anesthesia without tourniquet or sedation was used in hand surgery as a safe and efficient option for surgical interventions, known as WALANT (Wide Awake Local Anesthesia with No Tournique) technique. The aim of the study is to evaluate a prospective series of patients who have undergone surgery with the WALANT technique in hand surgery. Methods: Consecutive series of cases that show the performance of a local anesthetic technique for procedures in hand surgery without sedation and without tourniquet. Surgery time, intra and postoperative pain and satisfaction level were evaluated. This study was accepted by the ethics committee. Results: Ninety-six patients underwent surgery, seventy-three were soft tissue surgery and twenty-three bone surgery. Ninety-two patients (96%) reported being satisfied and without postoperative pain. In four cases, intraoperative sedation was necessary. No patient required a tourniquet. It was not necessary to use volumes greater than 40 ml; however, these vary according to the type of intervention. Conclusions: This study shows that the technique works very well and is very useful in tendon surgeries, where the patient is required to be awake to evaluate intraoperative functioning. Surgery costs are cheaper, and it is a reproducible technique with satisfactory performance.

En respuesta a esta situación se diseñaron propuestas asistenciales (un modelo teórico-asistencial, un manual para la organización procedimental y un modelo de historia clínica) en etapas investigativas anteriores. Objetivo: evaluar la satisfacción y calidad percibida por pacientes y familiares con la aplicación de un modelo asistencial, un manual de procedimientos y un modelo de historia clínica para el perfeccionamiento asistencial en cirugía mayor ambulatoria y cirugía de corta estadía. Métodos: desde el 4 de enero de 2016 hasta el 28 de diciembre de 2017 se efectuó un estudio cuasi-experimental para evaluar la satisfacción y calidad percibida por pacientes sin experiencia en cirugía mayor ambulatoria o de corta estadía y un familiar acompañante en cada caso. Se aplicó un diseño con un grupo experimental y otro de control solo con post-prueba para pacientes y familiares. Los grupos experimentales estuvieron constituidos por 50 pacientes y 50 familiares respectivamente y los grupos de control por 67 pacientes y 67 familiares. La satisfacción y calidad percibida fueron evaluadas mediante escalas ascendentes de 1 hasta 5 puntos. Resultados: se obtuvieron niveles más favorables en la satisfacción y percepción de la calidad en los pacientes y familiares de los grupos experimentales. Conclusiones: la aplicación de las propuestas asistenciales contribuyó al logro de elevados niveles de satisfacción y calidad percibida en los usuarios.

ABSTRACT Background: difficulties have been evidenced in the coordination between the primary and secondary health levels in the process of caring for patients in major outpatient surgery and short-stay surgery. In answer to this situation, healthcare proposals (a theoretical-healthcare model, a manual for procedural organization and a clinical history model) were designed in previous research stages. Objective: to evaluate the satisfaction and quality perceived by patients and relatives with the application of a care model, a procedure manual and a clinical history model for major outpatient surgery and short-stay surgery improvement of care. Methods: from January the 4th, 2016 to December the 28th, 2017, a quasi-experimental study was carried out to evaluate the satisfaction and quality perceived by patients with no experience in major outpatient or short-stay surgery and a companion relative in each case. A design was applied with an experimental group and a control group only with post-test for patients and relatives. The experimental groups consisted of 50 patients and 50 relatives respectively and the control groups of 67 patients and 67 relatives. Satisfaction and perceived quality were evaluated using ascending scales from 1 to 5 points. Results: more favorable levels of satisfaction and perception of quality were obtained in patients and relatives of the experimental groups. Conclusions: the application of the healthcare proposals contributed to the achievement of high levels of satisfaction and perceived quality in the users.

Analgesia para cirugía pediátrica ambulatoria / Pain management for pediatric ambulatory surgery

INTRODUCTION: Outpatient pediatric surgery is very frequent. However, sometimes analgesia is insufficient. Implementation of regional anesthesia reduces consume of systemic analgesics, especially opioids. The objective of this article is to review available evidence regarding pain management in pediatric ambulatory surgery, in order to contribute to better care of these patients in this field of medicine. A search was made on Pubmed, ProQuest, and EMBASE databases obtaining a total of 973 articles. The titles of articles found were reviewed, of which 152 merited greater review. Finally, a total of 40 articles to be included in this review were selected. RESULTS: Acetaminophen and nonsteroidal anti-inflammatory drugs are safe in children. Opioid use has de- creased to avoid potential adverse events. Advances in ultrasound technology have contributed to safer and efficient peripheral nerve blocks, comparable to neuroaxial techniques, decreasing the use of systemic analgesia, adverse events and allowing early discharge. CONCLUSIÓN: A multimodal approach handle perioperative pain adequately and minimize perioperative complications. With the use of ultrasound, regional anesthesia is a safe technique that offers multiple advantages in ambulatory surgical proce- dures, ensuring an early discharge. More evidence is needed to recommend the use of adyuvant drugs and continuos peripheral nerve blocks in children.

INTRODUCTION: La cirugía pediátrica es realizada frecuentemente en forma ambulatoria, sin embargo, la analgesia al alta es inadecuada en algunos casos. El uso de analgesia regional ha permitido disminuir el consumo de analgésicos sistémicos, particularmente opioides. El objetivo de este trabajo es revisar la evidencia disponible respecto a técnicas de manejo del dolor pos-operatorio en contexto de cirugía pediátrica ambulatoria, de manera de contribuir al mejor cuidado de estos pacientes en esta área de la medicina. Se realizó una búsqueda en Pubmed, Embase y ProQuest, encontrándose un total de 973 trabajos. Se revisaron los títulos, encontrando 152 de interés para mayor revisión. Se seleccionaron finalmente 40 trabajos para ser incluidos en esta revisión. RESULTADOS: Paracetamol y antiinflamatorios no esteroidales son seguros de usar en niños. El uso de opioides es cada vez menos frecuente dado su perfil de efectos adversos. Con el uso de ecografía los bloqueos de nervio periférico son cada vez más usados, logrando analgesia similar a las técnicas neuroaxiales, disminuyendo el consumo de analgésicos, efectos adversos y logrando un alta precoz. CONCLUSIÓN: La analgesia multimodal permite un adecuado manejo del dolor, reduciendo los efectos adversos. Gracias a la amplia disponibilidad de ultrasonido, la analgesia regional es cada vez más segura y eficaz, ofreciendo ventajas en el contexto de cirugía ambulatoria al permitir un alta precoz. Es necesaria más evidencia para recomendar el uso de adyuvantes y bloqueos continuos de nervio periférico en contexto de cirugía pediátrica ambulatoria.
