Analgesia por láser de baja potencia en pacientes con tratamiento ortodóncico / Low power laser analgesia in patients with orthodontic treatment i: en

Introducción: El dolor es el síntoma más común luego de la primera activación de la aparatología ortodóncica. El tratamiento analgésico más utilizado es el paracetamol; sin embargo, su uso inhibe la actividad de la ciclooxigenasa y la síntesis de prostaglandinas, lo que puede afectar el mecanismo del movimiento dental y el remodelado óseo. Objetivo: Evaluar la efectividad del láser de baja potencia para el alivio del dolor en pacientes con tratamiento ortodóntico. Métodos: Se realizó un estudio cuasiexperimental de intervención terapéutica, desde enero hasta diciembre de 2020, en 40 pacientes atendidos en la consulta de ortodoncia del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, en quienes se aplicaría fuerza ortodóncica por primera vez. Estos fueron distribuidos de forma aleatoria en 2 grupos de 20 integrantes cada uno: el de estudio, tratado con láser de baja potencia, y el de control, que recibió medicación convencional (paracetamol). Para la validación estadística de la información se emplearon el porcentaje y la prueba de la t de Student para muestras independientes, con 95 % de confiabilidad. Resultados: Luego de tres sesiones terapéuticas, 90,0 % del grupo de estudio refirió no presentar dolor o sentirlo de forma leve, mientras que del grupo de control solo 10,0 % de los pacientes fue ubicado en cualquiera de las dos categorías anteriores. Existió diferencia significativa entre ambos grupos (p=0,00). Conclusiones: Se demostró que el láser, como terapia alternativa, fue más efectivo que el paracetamol.

Introduction: Pain is the most common symptom after the first activation of orthodontic appliance. The most widely used analgesic treatment is paracetamol; however, its use inhibits cyclooxygenase activity and prostaglandin synthesis, which can affect the mechanism of tooth movement and bone remodeling. Objective: To evaluate the effectiveness of low power laser for pain relief in patients with orthodontic treatment. Methods: A quasi-experimental study of therapeutic intervention was carried out, from January to December 2020, in 40 patients treated at the orthodontic clinic of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, in whom orthodontic force was applied for the first time. These were randomly distributed into 2 groups of 20 members each: the study group, treated with low-power laser, and the control group, that received conventional medication (paracetamol). For statistical validation of data, the percentage and the Student's t test for independent samples were used, with 95 % confidence interval. Results: After three therapeutic sessions, 90.0% of the study group reported not presenting pain or feeling it slightly, while only 10.0% of patients in control group were put in any of the two previous categories. There was a significant difference between both groups (p=0.00). Conclusions: Laser, as an alternative therapy, was shown to be more effective than paracetamol.

Application of white noise therapy on the alleviation of hospital procedural pain of colostomy newborns / 中国实用护理杂志

Objective:To investigate the application value of white noise therapy on the alleviation of procedural pain of colostomy newborns.Methods:By a prospective, randomized and controlled trial, a total of 88 colostomy newborns in Hunan Children′s Hospital from January 2018 to January 2020 divided into experimental group (44 cases) and control group (44 cases) according to the random number table method. The control group received routine nursing; based on thesis, the experimental group played white noise intervention therapy on the basis of routine nursing. The intervention effect was assessed byNeonatal Infant Acute Pain Assessment Scale (NIAPAS), the first crying time and the duration of first crying, the first painful face and the duration of first painful face as well as heart rate and blood oxygen saturation.Results:The first crying time and the duration of first crying, the first painful face and the duration of first painful face were (28.05 ± 7.39) s, (46.18 ± 13.29) s, (32.89 ± 6.79) s, (52.75 ± 10.71) s in the experimental group, significantly shorter than in the control group (35.79 ± 5.81) s, (35.79 ± 5.81) s, (38.64 ± 10.53) s, (59.79 ± 13.52) s, the difference was statistically significant ( t values were 2.71-5.47, all P<0.05). During and after the procedure, the scores of NIAPAS were (6.32 ± 1.62) points, (4.18 ± 1.06) points in the experimental group, significantly lower than that in the control group (7.43 ± 1.78) points, (4.79 ± 1.34) points ( t=3.06, 2.38, both P<0.05); the heart rate were (152.82 ± 13.25) times/min and (147.84 ± 12.37) times/min in the experimental group, significantly lower than in the control group (166.11 ± 13.79) times/min and (155.77 ± 12.84) times/min ( t=4.61, 2.95, both P<0.05); the blood oxygen saturation were 0.979 8 ± 0.009 5 and 0.980 9 ± 0.012 4 in the experimental group, significantly higher than in the control group 0.969 1 ± 0.014 9, 0.972 3 ± 0.017 8, the difference was statistically significant ( t=4.01, 2.65, both P<0.05). Conclusions:White noise therapy can effectively alleviate procedural pain and stabilizing vital signs of colostomy newborns.

Efficacy of hypnosis in the management of non-procedural pain: systematic review / Eficácia da hipnose no manejo da dor não procedimental: revisão sistemática

ABSTRACT BACKGROUND AND OBJECTIVES: Pain has great impact on public health and presents a social cost which transcends the financial aspect. Hypnosis is a focal, quick and low-cost resource with effective change possibilities in pain management. The objective of this study was to identify evidence of the efficiency of hypnosis in pain management. CONTENTS: This study consists of a systematic literature review held in February 2020. Search was carried out in the Pubmed, Cochrane, LILACS, Scielo and PsycInfo platforms, using the keywords "clinical trials", "hypnosis", "pain management", "pain intensity", and "quality of life", totalizing 18 studies after peer review. Most articles are randomized, controlled by comparing hypnosis to standard treatment or other integrative practices, and focus mainly on the aspects of intensity, quality and interference of pain as an outcome variable. Six studies mention quality of life and only two refer catastrophization as an important intervening variable. CONCLUSION: Hypnosis is an effective technique for pain management, considering that there was an improvement in pain management with the improvement of at least one aspect, be it intensity, interference or quality of pain. However, it's necessary to highlight important limitations of the studies, such as the small sample size and the complexity of systematizing subjective techniques, which highlights the need for more clinical trials, including multicentric studies, so that larger samples can be obtained.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor tem um amplo impacto na saúde pública, apresentando um custo social que extrapola o financeiro. A hipnose mostra-se como recurso focal, breve e de baixo custo, com possibilidades efetivas de mudança no manejo da dor. O objetivo deste estudo foi verificar a eficácia da hipnose no manejo da dor não procedimental. CONTEÚDO: Trata-se de uma revisão sistemática da literatura realizada em fevereiro de 2020. As buscas foram realizadas nas plataformas Pubmed, Cochrane, LILACS, Scielo e PsycInfo, utilizando-se os descritores "ensaio clínico", "hipnose", "manejo de dor", "intensidade de dor" e "qualidade de vida", totalizando 18 estudos após a avaliação de pares. A maioria dos estudos era randomizada, controlada por comparação da hipnose com tratamento padrão ou outra prática integrativa e centrava-se principalmente nos aspectos de intensidade, qualidade e interferência da dor como variável desfecho. Seis estudos fazem menção à qualidade de vida e apenas dois se referem à catastrofização como variável interveniente importante. CONCLUSÃO: A hipnose é uma técnica eficaz no manejo da dor, considerando que houve melhora no manejo da dor a partir da melhora em, pelo menos, um aspecto, seja intensidade, interferência ou qualidade da dor. No entanto, é preciso ressaltar importantes limitações dos estudos, como o tamanho reduzido das amostras e a complexidade de sistematização das técnicas subjetivas, o que evidencia a necessidade de mais ensaios clínicos, inclusive multicêntricos, de modo a garantir amostras maiores.

Non-pharmacological Management of Procedural Pain in Children: Health Worker’s Approach at a Tertiary Health Facility, Southern Nigeria

Introduction: Pain is one of the most recurrent complaints obtainable in paediatric settings especially while carrying out procedures. The emergency section is averytaskingplaceforchildren. Hence itisimportant for health care workers to follow a child focussed or individual methods in their assessment and management of pain and painful procedures.Aim:To determine health workers’ approach towards non-pharmacological management of procedural pain in children at the University of Port Harcourt Teaching Hospital (UPTH). Methods: Thisdescriptive cross-sectional study was carried out between November 2019 and January 2020. A semi-structured questionnaire was used to retrieve information on biodata, knowledge and practice of non -pharmacological management of procedural pain in children. Data was entered into Microsoft Excel spread sheet and analysed using Statistical Package for Social Sciences version 21.Results: Respondents in this study included 25(24.8%) physicians and 61(60.4%) nurses. Forty-four respondents (43.5%) had more than 10 years’ workexperience. Self-development 59 (58.4%) was the most common source of knowledge of paediatric pain management. Fourteen(13.9%) respondents knewthe appropriate time of applying non-pharmacological measures of which distraction was the most common strategy mentioned (n=85, 84.2%) and used (36%). Nurses were significantly more knowledgeable about non-pharmacological methods of pain management in children (p= .000).Conclusion: There are gaps in knowledge and practice of clinicians concerning use of non-pharmacological interventions in the management of procedural pain in children. Development of a standard protocol would be an asset. There is need for necessary tools, and institutional commitment to adequate pain relief for children in our institution

Características clínicas da doença de Parkinson associadas à dor ao tratamento odontológico / Clinical characteristics of Parkinson's disease associated with dental treatment-related pain

Resumo Introdução A Doença de Parkinson (DP) resulta em condições clínicas desfavoráveis para a saúde bucal e não existe estudo publicado sobre dor ao tratamento odontológico em pacientes com DP. Objetivo Pesquisar associação entre características clínicas da DP e a intensidade de dor em decorrência de tratamentos odontológicos. Material e método Foi utilizada uma amostra consecutiva de 70 pacientes com DP, nos quais foram realizados 217 procedimentos odontológicos invasivos. Tempo de DP foi coletado do prontuário odontológico; estágio da DP foi definido por meio da escala de Hoehn e Yahr; défice cognitivo, por meio do Mini Exame do Estado Mental; depressão, por meio do Inventário de Depressão de Beck; e comprometimento motor, por meio da escala UPDRS/AVD. Os pacientes foram questionados se no último mês sentiram alguma sensação de dormência, formigamento, queimação ou dor bem como dificuldade para sentir cheiros ou gostos. A dor relacionada ao tratamento foi coletada por meio de uma escala numérica de dor com valores de 0 a 10. Resultado O nível de dor percebida pelos pacientes durante o tratamento odontológico não apresentou associação significativa com tempo de DP, estágio da DP, comprometimento motor nem ocorrência de depressão. Maior nível de dor foi estatisticamente mais frequente entre aqueles com défice cognitivo e aqueles que relataram a presença de maior número de sintomas sensitivos, sobretudo dormência e queimação. Conclusão A dor ao tratamento odontológico em pacientes com DP está associada aos sintomas não motores desses pacientes, especificamente o défice cognitivo e a presença de sintomas sensitivos.

Abstract Introduction Parkinson's disease (PD) results in unfavorable clinical conditions for oral health and there is no published study on pain during dental treatment in PD patients. Objective To investigate association between clinical characteristics of PD and the intensity of pain due to dental treatments. Material and method A consecutive sample of 70 patients with PD was used, in which 217 invasive dental procedures were performed. PD duration was collected from dental records; PD stage was defined using the Hoehn and Yahr scale; cognitive deficit, using the Mini Mental State Examination; depression, using the Beck Depression Inventory; and motor impairment, using the UPDRS-AVD scale. Patients were asked whether in the last month they felt any numbness, tingling, burning or pain sensation; as well as difficulty in smelling or tasting. Treatment-related pain was collected using a Numerical Pain Scale with values ranging from 0 to 10. Result the level of pain perceived by patients during dental treatment was not significantly associated with PD duration, PD stage, motor impairment or occurrence of depression. The frequency of patients who reported a higher level of pain was statistically higher among those with cognitive impairment and those who reported the presence of a greater number of sensory symptoms, especially numbness and burning. Conclusion Pain related to dental treatment in PD patients is associated with non-motor symptoms of these patients, specifically the cognitive impairment and the presence of sensory symptoms.

The Effect of Behavioral Relaxation Training on Distress and Cancer Screening Intention of Patients with Upper Gastrointestinal Endoscopy / 한국간호교육학회지

PURPOSE: This study evaluates the effect of behavioral relaxation training on distress and cancer screening intention of patients with upper gastrointestinal endoscopy.METHODS: The research was conducted in a non-equivalent control group posttest design. Data were collected from endoscopy subjects in B city from October to November of 2018. Fifteen minutes of behavioral relaxation training were provided to the experimental group (n=40) and traditional relaxation therapy methods were provided to the control group (n=40). Outcome measures were distress and cancer screening intention of patients with upper gastrointestinal endoscopy. Data were analyzed with a χ²-test, independent t-test, Fisher's exact test with SPSS/PC version 23.0.RESULTS: The objective discomfort (t=8.81, p<.001) of the experimental group was lower than that of the control group; there were no significant differences in the subjective discomfort (t=1.73, p=.088). The cancer screening intention (t=−5.85, p<.001) of the experimental group was significantly higher than that of the control group.CONCLUSION: Behavioral relaxation training was effective in heightening cancer screening intention. Therefore it can be usefully applied to increase cancer screening intention.

Epidemiology of painful procedures in premature and influencing factors in intensive care unit / 中国小儿急救医学

Objective To report epidemiological data on neonatal pain collected from a geographi-cally defined region,and analyze its influencing factors. Methods We prospectively collected data on all painful procedures from the first 3 days of admission from 106 premature by using self-made questionnaire. Results One hundred and six premature infants experienced 8 167 first-attempt procedures during the first 3 days of admission,26 painful procedures per premature per day. The top seven were respectively plaster re-moval 1 661(20. 3%),nasal aspiration 1 416(17. 3%),blood sugar testing 982(12. 0%),foil removal 833 (10. 2%),intravenous cannula 806(9. 9%),removal of intravenous line 803(9. 8%),arterial puncture 696 (8.5%); 640(7.8%)supplemental attempts were performed. Arterial puncture 274(42.8%)and intrave-nous cannula 235 (36. 7%) were the top two painful procedures easily failed. Non-invasive ventilation,me-chanical ventilation,neonatal respiratory distress syndrome and low weight were the risk factors of painful procedures. Conclusion In neonatal intensive care unit,large number of painful procedures are performed in the first 3 days of admission. Healthcare providers should develop individualized measures to promote the man-agement of premature pain.

Clinical management of procedural pain in the neonate:policy statement of prevention and management of procedural pain in the neonate by American Academy of Pediatrics Committee on Fetus and New-born and Section on Anesthesiology and Pain Medicine / 中国小儿急救医学

Neonatal pain is a common phenomenon. For a long time neonatal pain had not been focus on properly and managed appropriately. American Academy of Pediatrics Committee on Fetus and Newborn and Section on Anesthesiology and Pain Medicine published policy statement to emphasize the necessity of neonatal pain assessment,and summarize the neonatal operability pain assessment method,drug and non-drug control measures,also update prevention and management of procedural pain in the neonate in 2016. Until today the guideline for neonatal pain management has not yet been released in China. As the reference for clinicians in domestic,the content of policy statement will be reorganized and introduced.

Carbon Dioxide versus Air Insufflation in Gastric Endoscopic Submucosal Dissection: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) with air insufflation is commonly used for the staging and treatment of early gastric carcinoma. However, carbon dioxide (CO2) use has been shown to cause less post-procedural pain and fewer adverse events. The objective of this study was to compare the post-procedural pain and adverse events associated with CO₂ and air insufflation in ESD. METHODS: A systematic search was conducted for randomized control trials (RCTs) comparing the two approaches in ESD. The Mantel-Haenszel method was used to analyze the data. The mean difference (MD) and odds ratio (OR) were used for continuous and categorical variables, respectively. RESULTS: Four RCTs with a total of 391 patients who underwent ESD were included in our meta-analysis. The difference in maximal post-procedural pain between the two groups was statistically significant (MD, -7.41; 95% confidence interval [CI], -13.6 – -1.21; p=0.020). However, no significant differences were found in the length of procedure, end-tidal CO2, rate of perforation, and postprocedural hemorrhage between the two groups. The incidence of overall adverse events was significantly lower in the CO2 group (OR, 0.51; CI, 0.32–0.84; p=0.007). CONCLUSIONS:: CO2 insufflation in gastric ESD is associated with less post-operative pain and discomfort, and a lower risk of overall adverse events compared with air insufflation.

Expressed Breast Milk vs 25% Dextrose in Procedural Pain in Neonates: A Double Blind Randomized Controlled Trial.

Objective: To compare the effect of expressed breast milk (EBM), 25% dextrose (25 D) and sterile water (SW) on procedural pain in neonates as assessed by the premature infant pain profile (PIPP), changes in heart rate (HR), oxygen saturation (SpO2) and duration of crying. Design: Prospective, double blind, randomized controlled trial. Setting: Postnatal ward of a tertiary-care hospital. Participants: 210 babies who required venipuncture for blood sampling and who were on oral feeds were recruited into the study after parental informed consent. Methods: The enrolled babies were randomized into intervention groups (EBM, 25% dextrose) and control group (sterile water). Two ml of test solution was given to baby by paladay (a traditional cup with a spout) 2 min before venipuncture. The face and crying of baby were video graphed by an independent, blinded observer. The facial response to pain (brow bulge, eye squeeze, nasolabial furrow) was analysed from the video. Maximum HR and minimum SpO2 were recorded during, and 1, 3 and 5 min after venipuncture by another blinded observer. Outcome variable: :PIPP score, HR, SpO2 and crying time at 0/ 1/3/5 min after sampling. Results: 160 babies were considered for final analysis with 50 in 25 D, 62 in EBM and 48 in SW group. The mean PIPP score in the 3 groups were 5.22, 6.84 and 11.22 at 0-30 sec after venipuncture; 4.52, 6.34, and 10.88 at 1-1 ½ min; 3.96, 6.15 and 9.35 at 3-3 ½ min; and 3.12, 4.68 and 7.83 at 5-5 ½ min; respectively (P< 0.001). The median crying time was 10 ,37.5 and 162 seconds in 25 D, EBM and SW groups, respectively (P< 0.001). Conclusions: EBM significantly reduces procedural pain in neonates though to a lesser extent as compared to 25% dextrose.

Difference of Anxiety of Parents: before & after the VCUG

PURPOSE: The voiding cystourethrogram (VCUG) is the investigation of choice in detecting the vesicoureteral reflux in urinary tract infections in children. As it is a potentially distressing and invasive test, most of the parents are so concerned about the child's stress. In this study, we compared the difference of the state of anxiety of parents before and after the VCUG. METHODS: We divided 68 parents whose children underwent VCUG into 2 groups; who have given an explanation about VCUG in detail using pictures (group 1) Vs. who have given an oral explanation only (group 2). All the parents submitted the same questionnaire 2 times before and after the VCUG, which consisted of State-Trait-Anxiety-Inventory X-I (STAI-X-I) and visual analog scale (VAS) on the perception of worry, anxiety, confusion and pain. RESULTS: Before VCUG, the perception of pain was higher in group 1 (P < 0.05). After VCUG, the anxiety and confusion were significantly higher in group 2 than group 1 (P < 0.05). In group 1, STAI-X-I scores, the perception of worry and anxiety were significantly decreased after the VCUG (P < 0.05). In group 2, the confusion and pain were increased after VCUG (P < 0.05). CONCLUSION: It showed that doctor's explanation on the procedure in advance may raise the perception of pain and the possibility of refusal by parents. But the STAI-X-I, worry, anxiety after VCUG were significantly decreased in group 1, while the confusion and pain were increased in group 2. Therefore we suggest that prior and sufficient explanation about invasive procedure like VCUG can be helpful in ameliorating the anxiety of the parents.

Dolor en el trauma térmico / Pain in thermal trauma

La máxima agresión física que puede sufrir un ser humano son las quemaduras. Actualmente, en Chile se hospitalizan alrededor de 9.000 personas al año por quemaduras, con una tasa de mortalidad que ha ido en disminución en los últimos 20 años, por lo tanto la cantidad de pacientes sobrevivientes va en aumento. La IASP (Internacional Association for Study of Pain) definió el dolor en quemados como: "un dolor agudo y grave, que se produce al sufrir una quemadura y luego continuo con exacerbaciones que declinan gradualmente". El dolor en el trauma térmico está siempre presente, es de intensidad severa y prolongada en el tiempo, con una alta prevalencia de dolor crónico. Se sabe que el aumento en la intensidad se debe a que las quemaduras dañan gran cantidad de nociceptores, produciéndose una amplificación de la respuesta al dolor. Los opioides son el principal pilar en el tratamiento farmacológico. Es fundamental el buen manejo del dolor, para evitar el dolor patológico que aumentará el dolor crónico y con ello el desmedro de la vida personal de nuestros pacientes. Desafortunadamente el subtratamiento es una realidad, produciendo directamente un retraso en la recuperación de sus quemaduras y en la inserción social y laboral.

Burns are the greatest physical aggression that a human being can experience. In Chile, approximately 9000 patients are hospitalized annually due to burns, with a mortality rate that has decreased progressively in the last 20 years, which means that the amount of survivors is increasing. The IASP (International Association for Study of Pain) has defined pain in the burn patient as "an acute and severe pain produced by a burn that later continues with exacerbations that gradually decline". Pain in thermal trauna is always present, of severe intensity and prolonged in time, with a high prevalence of chronic pain. It is Known that the increase in intensity of pain is due to the damage of a great number of nociceptors, that produces an amplification of the response to pain. Opioids are the mainstay of pharmacologic treatment. Appropriate management of pain is fundamental to avoid pathologic pain that will increase the chronic pain and deteriorate the quality of life of our patients. Unfortunately undertreatment is a reality, retarding the healing of the burn wound, and the social and workplace reintegration.
