Comparison between oral midazolam versus oral ketamine plus midazolam as preanesthetic medication in autism spectrum disorder: double-blind randomized clinical trial

Abstract Background: Conventional dental care is often impossible in patients with Autism Spectrum Disorder (ASD). Non-collaborative behaviors, sometimes associated with aggressiveness, are usual justifications for premedication in this population. Thereby, this research focuses on the effects of oral midazolam versus oral ketamine plus midazolam as preanesthetic medication in ASD. Methods: The sample included 64 persons with ASD, aged 2-59 years, scheduled for dental care under general anesthesia. The primary objective of this study was to compare degrees of sedation between two parallel, double-blinded, equally proportional groups randomized to receive oral midazolam (0.5 mg.kg−1, maximum 15 mg) or oral midazolam (0.5 mg.kg−1) associated with oral S(+)-ketamine (3 mg.kg−1, maximum 300 mg). The secondary outcomes were the need of physical stabilization to obtain intravenous line, awakening time, and occurrence of adverse events. Results: According to the dichotomous analysis of sedation level (Ramsay score 1 and 2 versus Ramsay ≥ 3), oral association of S(+)-ketamine and midazolam improved sedation, with increased probability of Ramsay ≥ 3, Relative Risk (RR) = 3.2 (95% Confidence Interval [95% CI] = 1.32 to 7.76) compared to midazolam alone. Combined treatment also made it easier to obtain venous access without physical stabilization, RR = 2.05 (95% CI = 1.14 to 3.68). There were no differences between groups regarding awakening time and the occurrence of adverse events. Conclusion: The association of oral S(+)-ketamine with midazolam provides better preanesthetic sedation rates than midazolam alone and facilitates intravenous line access in patients with autism.

Introduction: The preanesthetic evaluation, documenting it and maintaining the record is the responsibility of anesthetist. Better documentation practices can improve the patient's outcome. It has the pivotal role in medicolegal aspects. However, the documentation is one of the challenges when it comes to quality of care. The objective of the study was to assess the practice of documentation at preanesthetic evaluation and completeness of Preanesthetic evaluation tools. The descriptive study was conducted in tertiary care hospital. Modied global quality index (GQI) isMethod: used to prepare the Predefined twenty-two indicators. The data analysis is done using SPSS version-20. A total ofResult: 300 pre-anesthetic evaluation tools (PAETs) were reviewed. There was different trend in terms of completion rate for elective and emergency cases. However, there was no PAETs found complete. Indicators with high completion rate (>90%) were signed a consent, past medical history (PMH), history of medication, allergy, surgical procedure, cardiovascular examination, airway examination and respiratory examination. Anesthetic plan, premedication, vital signs, a name, per-oral status and age were found with below average (<50%) completion rate. andConclusion recommendations: Documentation during the preanesthetic visit observed below the standard. Which need to be standardized for uniformity. Use of electronic system with prefilled formats and training of personnel involved in the process is the way forward

Oral preanesthetic medication in children - comparison between midazolam alone and in combination with ketamine: a systematic review and meta-analysis

Abstract Background Up to 60% of pediatric surgical patients develop high levels of preoperative anxiety. This study compared the effects of oral combinations of midazolam and ketamine with oral midazolam alone for pediatric preanesthetic medication. Methods The study protocol was registered in PROSPERO as CRD42020172920. A systematic literature search was conducted using Medline, Cochrane, EMBASE, CENTRAL, and Web of Science for randomized controlled trials comparing oral combinations of midazolam and ketamine with midazolam alone as preanesthetic medication in elective surgical pediatric patients. Meta-analyses included the following outcomes: anxiety and sedation levels, child's behavior during separation from parents, face mask acceptance, and venipuncture. The quality of evidence was assessed using GRADE criteria. Results Twenty studies were included. The following effects (RR (95% CI)) were observed for combinations of ketamine and midazolam relative midazolam alone: anxiolysis (1.2 (0.94-1.52); p= 0.15; I2 = 80%; GRADE = very low); satisfactory sedation (1.2 ( 1.10-1.31); p< 0.001; I2 = 71%; GRADE = very low); behavior during parental separation (1.2 (1.06-1.36); p= 0.003; I2 = 88%; GRADE = very low); facial mask acceptance (1.13 (1.04-1.24); p= 0.007; I2 = 49%; GRADE = very low); behavior during venipuncture (1.32 (1.11-1.57); p= 0.002; I2 = 66%; GRADE = very low). Conclusions While similar probabilities of obtaining anxiolysis were found, adequate sedation, calm behavior during child's separation from parents, low levels of fear during face mask adaptation, and cooperative behavior during peripheral venous cannulation were more likely with midazolam-ketamine combinations.

The effect of intravenous prophylactic administration of dezocine before anesthesia induction on choking during induction period of patients undergoing general anesthesia / 中国医师进修杂志

Objective:To investigate the effect of intravenous prophylactic administration of dezocine before anesthesia induction on choking during induction period in patients undergoing general anesthesia.Methods:A total of 92 patients with tracheal intubation surgery under general anesthesia from November 2020 to May 2021 in the Zhejiang Taizhou Hospital were selected and randomly divided into the observation groupand the control group by random number table, with 46 cases in each group. The observation group was intravenously injected with 0.1 mg/kg dezocine while the control group was intravenously injected with 0.9% sodium chloride 5 ml before anesthesia induction. Anesthesia induction was performed at 10 min after injection in the two groups. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and catecholamine, interleukin-6 (IL-6) levels were recorded at before anesthesia induction (T 0), 1 min before endotracheal intubation (T 1), 1 min after intubation (T 2), and 5 min after endotracheal intubation (T 3). The incidence and degree of choking, the agitation score, visual analog scale (VAS) score, Ramsay sedation score and the incidence of adverse reactions in the two groups were compared. Results:The levels of HR, SBP and DBP at T 0, T 1, T 2 and T 3 in the two groups had no significant differences ( P>0.05). The levels of catecholamine and IL-6 in the control group were higher than those in the observation group: (120.49 ± 15.13) ng/L vs.(113.53 ± 17.14) ng/L, (16.80 ± 2.61) ng/L vs. (13.46 ± 1.55) ng/L, there were statistical differences ( P<0.05). The recovery time to spontaneous breathing in the observation group was shorter than that in the control group: (8.76 ± 2.14) min vs. (9.87 ± 2.09) min, there was statistical difference ( P<0.05). The incidence of choking in the observation group was lower than that in the control group: 2.17%(1/46) vs. 21.74%(10/46), there was statistical difference ( P<0.05). The scores of agitation score and VAS in the observation group were lower than that in the control group, and the scores of Ramsay sedation score was higher than that in the control group: (1.43 ± 0.26) scores vs. (2.11 ± 0.14) scores, (3.55 ± 1.03) scores vs. (4.86 ± 1.15) scores, (3.13 ± 0.76) scores vs. (1.54 ± 0.32) scores, there were statistical differences ( P<0.05). The incidence of adverse reactions in the observation group was lower than that in the control group: 6.52%(3/46) vs. 23.91% (11/46), there was statistical differences ( χ2 = 5.39, P<0.05). Conclusions:For patients with tracheal intubation under general anesthesia, preventive injection of dezocine before anesthesia induction can effectively inhibit the stress response of patients, with little impact on the patients′ circulatory system and respiratory system, and can also effectively reduce the incidence of choking in the induction period.

La valoración preanestésica del paciente pediátrico durante la pandemia por COVID-19 / Preanesthetic assessment of the pediatric patient during the COVID-19 pandemic

Resumen: En la pandemia actual por SARS-CoV-2, poca atención se ha puesto a la población pediátrica debido a su baja morbimortalidad. Debido al amplio espectro de presentación de esta enfermedad en los pacientes pediátricos, es necesario reconocer sus diferentes presentaciones clínicas y la importancia de la valoración preanestésica en procedimientos electivos y de urgencia a fin de evitar la exposición del personal de salud a pacientes contagiados y disminuir la morbilidad perioperatoria en el paciente pediátrico con COVID-19.

Abstract: In the current SARS-CoV-2 pandemic, little attention has been paid to the pediatric population due to its low morbidity and mortality. Due to the wide spectrum of presentation of this disease, in pediatric patients, it is necessary to recognize its different clinical presentations and the importance of pre-anesthetic evaluation in elective and emergency procedures in order to avoid the exposure of health personnel with infected patients and to reduce the perioperative morbidity in the pediatric patient with COVID-19.

Importancia del anestesiólogo en la prevención del dolor crónico / Importance of the anesthesiologist in the prevention of chronic pain

The development of chronic pain after surgery or persistent postoperative pain is a significant public health problem that affects between 10%-56% of patients undergoing surgical intervention. It produces great restrictions of mobility, limitation of daily activities, dependence on opioids, anxiety, depression, a great alteration of the quality of life and important legal and medical-economic consequences. There is a very close correlation between acute postoperative pain, and persistent postoperative pain. For this reason, pain must be treated effectively in its acute phase to reduce the incidence of chronic pain after surgery. There are risk factors that predispose to its appearance and that must be known by the anesthesiologist. In an individualized and meticulous pre-anesthetic consultation, these risk factors can be detected, as well as the presence of surgical procedures related to chronic pain, with the purpose of the therapeutic approach of the first ones if necessary, and a good planning of the anesthetic and analgesic technique, which reduces the participation of the second, in the chronicity of acute pain. The role of the anesthesiologist in the pre-anesthetic consultation is essential for the planning of preventive and multimodal analgesia that, together with other resources, should reduce the incidence of persistent postoperative pain.

El desarrollo del dolor crónico después de la cirugía o dolor posoperatorio persistente, es un problema de salud pública significativo que afecta entre el 10%-56% de los pacientes sometidos a una intervención quirúrgica. Produce grandes restricciones de la movilidad, limitación de las actividades de vida diaria, dependencia a los opioides, ansiedad, depresión, una gran alteración de la calidad de vida e importantes consecuencias legales y médico-económicas. Hay una correlación muy estrecha entre el dolor agudo posoperatorio, y el dolor posoperatorio persistente. Por esa razón, el dolor debe ser tratado de manera eficaz en su fase aguda para disminuir la incidencia del dolor crónico posterior a la cirugía. Existen factores de riesgo que predisponen a su aparición y que deben ser conocidos por el anestesiólogo. En una consulta pre-anestésica individualizada y minuciosa, se podrán detectar estos factores de riesgo, como también la presencia de procedimientos quirúrgicos relacionados con el dolor crónico, con la finalidad del abordaje terapéutico de los primeros de ser necesario, y una buena planificación de la técnica anestésica y analgésica, que disminuya la participación de los segundos, en la cronicidad del dolor agudo. El rol del anestesiólogo en la consulta pre-anestésica, es fundamental para la planificación de la analgesia preventiva y multimodal que junto a otros recursos deberían disminuir la incidencia del dolor postoperatorio persistente.

Frequência de via aérea difícil em pacientes submetidos à anestesia geral em um hospital do Sul de Santa Catarina / Frequency of difficult airway tract in pacients submitted to general anesthesia in South Santa Catarina hospital

Justificativa e Objetivos: Avaliar via aérea difícil nos pacientes submetidos à ventilação e intubação orotraqueal sob anestesia geral para operações eletivas. Método: Estudo observacional com desenho transversal. Foram estudados um total de 163 pacientes, de 18 a 80 anos submetidos à ventilação sob máscara facial e intubação traqueal em operações com uso de anestesia geral. Os dados foram coletados na consulta pré-anestésica através de questionário que continha os parâmetros antropométricos e clínicos para intubação difícil. Resultados e Conclusões: Foram investigados 163 pacientes. Houve a presença de via aérea difícil em 19% dos pacientes, e a grande maioria não teve complicações. Ainda, houve uma maior frequência de via aérea difícil em pacientes com maior IMC e maior circunferência cervical, sendo ambos estatisticamente significativos. Foi observado também que quanto maior a classe do Mallampati maior a prevalência de encontrar-se uma classe maior que três na classificação de Cormack e Lehane, assim como maior a chance de se ter uma via aérea difícil, sendo significativo. Por fim, a prevalência de via aérea difícil encontrada é baixa, e quando presente geralmente está relacionado com fatores que podem ser prevenidos. As classificações quando utilizadas juntas tem maior chance de prever a via aérea difícil.

Rationale and Objectives: To evaluate difficult airway in patients submitted to ventilation and orotracheal intubation under general anesthesia for elective operations. Method: Observational study with cross-sectional design. A total of 163 patients, 18 to 80 years old undergoing ventilation under face mask and tracheal intubation in operations using general anesthesia were studied. The data were collected in the pre-anesthetic consultation through a questionnaire that contained the anthropometric and clinical parameters for difficult intubation. Results and Conclusions: 163 patients were investigated. There was a difficult airway presence in 19% of the patients, and the vast majority had no complications. Also, there was a higher frequency of difficult airway in patients with higher BMI and greater cervical circumference, both of which were statistically significant. It was also observed that the higher the Mallampati class the higher the prevalence of finding a class higher than three in the classification of Cormack and Lehane, as well as the greater the chance of having a difficult airway, being significant. Finally, the prevalence of difficult airways found is low, and when present geographically it is related to factors that can be prevented. Classifications when used together have a greater chance of predicting difficult airway.

Effect of pre-anesthetic fasting on gastric emptying and plasma glucose in healthy dogs of different age groups / Efeito do jejum pré-anestésico sobre o esvaziamento gástrico e a glicemia plasmática em cães hígidos de diferentes faixas etárias

Gastric emptying and plasma glucose were evaluated in young and adult dogs, fed with dry and wet food, submitted to different periods of pre-anesthetic fasting (6, 8, and 12 hours). Forty healthy dogs were selected, which were segmented into four groups according to the age group and type of diet. It was evaluated the gastric emptying by ultrasound and serum glycemia. Only 17.5% presented complete gastric emptying, and no significant differences were found between the 6 and 8-hour fasting evaluations, or between the age groups and the diets, considering significance level p<0.05. Mean plasma glucose values from the groups indicated normal glycemia at all times of evaluation. A significant difference was found between the means of glycemia in young and adult dogs, with the 8-hour fasting with wet diet (p=0.03) and with 12 hours with dry diet (p=0.04). Healthy young and adult dogs, in physiological equilibrium, maintain average values of plasma glucose despite prolonged periods of pre-anesthetic fasting, which may be necessary, since 8-hour fasting for solid food is not enough to provide complete gastric emptying.(AU)

Avaliou-se o esvaziamento gástrico e a glicemia plasmática em cães jovens e adultos, alimentados com ração seca e úmida, submetidos a diferentes períodos de jejum pré-anestésico (6, 8 e 12 horas). Foram selecionados 40 cães hígidos, os quais foram segmentados em 4 grupos de acordo com a faixa etária e o tipo de dieta administrada. Foi avaliado o esvaziamento gástrico por ultrassonografia e a glicemia sérica. Apenas 17,5% apresentaram completo esvaziamento gástrico, não sendo encontradas diferenças significativas entre as avaliações com 6 e 8 horas de jejum, ou entre as faixas etárias e dietas, considerando nível de significância p<0,05. Os valores médios da glicose plasmática dos grupos indicaram normoglicemia em todos os momentos de avaliação. Foi encontrada diferença significativa entre as médias da glicemia dos cães jovens e adultos, no período de 8 horas de jejum com dieta úmida (p=0,03) e com 12 horas nos animais com dieta seca (p=0,04). Conclui-se que cães hígidos jovens e adultos, em equilíbrio fisiológico, mantêm valores normais de glicemia plasmática apesar de períodos prolongados de jejum pré-anestésico, os quais podem ser necessários, tendo em vista que 8 horas de jejum alimentar de sólidos não é suficiente para proporcionar completo esvaziamento gástrico.(AU)

A Comparative Study Between Intranasal Midazolam and Ketamine as Premedication in Pediatric Patients

Introduction: Surgery and anesthesia can be a traumatic experience for a child. Stormy induction of anesthesia in children canlead to an increased incidence of post-operative behavioral problems. Thus, sedative premedication may be used in childrento aid smooth induction of anesthesia. Hence, this study was conducted to compare the preanesthetic sedative effects ofintranasal midazolam and ketamine.Materials and Methods: This study was carried out on 60 ASA Grades I and II pediatric patients aged 2–5 years undergoingemergency or elective surgery lasting for 30 min–2 h. The exclusion criteria were established. Patients were included after writteninformed consent of the parent/guardian. They were randomly divided into two groups: Group M and Group K. Pre-operative,intraoperative, and post-operative parameters were observed.Results: Statistically significant tachycardia and increased blood pressure (BP) (both clinically insignificant) were observed inboth the groups (more persistent in the ketamine group). The sedation by both the drugs was adequate in terms of parentalseparation score, acceptance of facemask and response to venipuncture with no statistically significant difference. There werealso no significant side effects (namely, respiratory depression, increased secretions or emergence reaction).Conclusion: Both the drugs midazolam and ketamine provide adequate preanesthetic sedation through intranasal route andare safe to use in pediatric patients without any significant side effects.

Oral versus intramuscular midazolam for paediatric preanaesthetic medication

Background: The need for effective preanesthetic medication in children is obvious and midazolam has proven to be one reliable choice. The aim of the present study was to compare the efficacy, acceptability and reliability of the oral and intramuscular routes of administration of midazolam towards paediatric preanesthetic medication at various doses.Methods: Hundred eligible patients in the age group of 1 to 10 years undergoing ambulatory or routine planned, minor or major surgery during study period were allocated to one of the four groups of 25 participants each, formed on the basis of premedication they received. Haemodynamic parameters, level of sedation and anxiety and induction score were noted before premedication and after each 15 minutes interval for next 45 minutes in all the four groups. Postoperative assessment included sleep level, anterograde amnesia, picture recall and occurrence of complications.Results: The sedative and anxiolytic effects were observed to be maximum at 45 minutes after premedication in all the four groups and better sedation, anxiolysis and quality of induction were achieved with higher doses for both oral as well as intramuscular routes. Postoperatively, the sleep level did not increase with higher dose and 64% patients were awake with 0.75 mg/kg oral midazolam. The sleep level was more with higher dose with the Intramuscular route, with 60% patients feeling drowsy with 0.1mg/kg dose. 0.75 mg/kg dose showed better anterograde amnesia (64%) than 0.5 mg/kg (28%), while it was present in 64% participants premedicated with 0.8 mg/kg intramuscular does and 72% in 0.1 mg/kg intramuscular dose.Conclusions: Intramuscular midazolam at 0.1 mg/kg dose seems to be the ideal dose and route for paediatric preanesthetic medication, with oral midazolam at 0.75 mg/kg to be considered an effective and acceptable alternative.

Preoperative education reduces preoperative anxiety in cancer patients undergoing surgery: Usefulness of the self-reported Beck anxiety inventory / A informação no pré-operatório reduz a ansiedade pré-operatória em pacientes com câncer submetidos à cirurgia: utilidade do Inventário Beck de Ansiedade

Abstract Background and objectives: Preoperative instruction is known to significantly reduce patient anxiety before surgery. The present study aimed to investigate the effects of preoperative education on the level of anxiety of cancer patients undergoing surgery using the self-reported Beck anxiety inventory. Methods: This study is a short-term observational study, including 72 female patients with a diagnosis of endometrial cancer who were scheduled to undergo surgical treatment under general anesthesia. During the pre-anesthetic consultation 15 days before surgery, one group of patients (Group A, n = 36) was given comprehensive information about their scheduled anesthetic and surgical procedures, while the other group of patients (Group B, n = 36) did not receive any information pertaining to these variables. The Beck anxiety inventory, blood pressure and heart rate were evaluated before and after the preoperative education in Group A. In Group B, these parameters were evaluated at the beginning and at the end of the consultation. Results: The hemodynamic values were lower in the group that received preoperative education, in comparison with the group that did not receive preoperative education. Educating the patients about the procedure resulted in a reduction in the levels of anxiety from mild to minimum, whereas there was no change in the group that did not receive the preoperative education. This latter group kept the same level of anxiety up to the end of pre-anesthetic consultation. Conclusions: Patient orientation in the preoperative setting should be the standard of care to minimize patient anxiety prior to surgery, especially for patients with cancer.

Resumo: Justificativa e objetivos: A informação transmitida no pré-operatório é conhecida por reduzir de modo significativo a ansiedade do paciente antes da cirurgia. O presente estudo teve como objetivo investigar os efeitos da orientação pré-operatória sobre o nível de ansiedade de pacientes com câncer submetidos à cirurgia, utilizando o inventário Beck de ansiedade. Métodos: Estudo observacional de curto prazo, incluindo 72 pacientes do sexo feminino com diagnóstico de câncer endometrial, programadas para receber tratamento cirúrgico sob anestesia geral. Durante a consulta pré-anestésica, 15 dias antes da cirurgia, um grupo de pacientes (Grupo A, n = 36) recebeu informações abrangentes sobre seus procedimentos anestésicos e cirúrgicos, enquanto o outro grupo de pacientes (Grupo B, n = 36) não recebeu qualquer informação referente a essas variáveis. O inventário Beck de ansiedade, a pressão arterial e a frequência cardíaca foram avaliados antes e após a transmissão de informações ao Grupo A. No Grupo B, esses parâmetros foram avaliados no início e no final da consulta. Resultados: Os valores hemodinâmicos foram menores no grupo que recebeu informação pré-operatória, em comparação com o grupo que não recebeu informação pré-operatória. Informar os pacientes sobre o procedimento resultou em uma redução dos níveis de ansiedade de leve a mínimo, enquanto não houve mudança no grupo que não recebeu informação pré-operatória. Esse último grupo manteve o mesmo nível de ansiedade até o final da consulta pré-anestésica. Conclusões: A orientação do paciente no período pré-operatório deve ser o atendimento padrão para minimizar a ansiedade dos pacientes antes da cirurgia, especialmente os pacientes com câncer.

Classificação anestésica do estado físico e mortalidade anestésico-cirúrgica em cães / Anesthetic classification of the physical status and surgical-anesthetic mortality in dogs

A classificação de estado físico ASA (Sociedade Americana de Anestesiologistas) é uma ferramenta importante para a avaliação pré-anestésica do paciente. Assim, é utilizada em diversos estudos por possuir estreita relação com a morbidade e a mortalidade anestésica. Realizou-se tal classificação em 243 pacientes caninos submetidos a procedimentos cirúrgicos em um Hospital Veterinário Universitário. Os resultados obtidos foram os seguintes: ASA I (38; 15,64%), ASA II (53; 21,81%), ASA II emergencial (E) (2; 0,82%), ASA III (78; 32,10%), ASA III E (23; 9,46%), ASA IV (11; 4,53%), ASA IV E (36; 14,81%) e ASA V (2; 0,82%). Verificou-se que a maior parte dos pacientes foram classificados como ASA III (doença sistêmica moderada), o que demonstra que, no serviço analisado, a maioria dos animais submetidos à cirurgia são portadores de enfermidades. A mortalidade foi de 2,46%, com a maioria dos óbitos ocorridos no pós-operatório e em pacientes com emergências. Concluiu-se que, no serviço analisado, os maiores riscos estão relacionados aos pacientes com categorias ASA de maior gravidade, em cirurgias emergenciais e, especialmente, no período pós-operatório.(AU)

The classification ASA (American Society of Anesthesiologists) is an important tool for assessing a patient's pre anesthetic. Thus, it is used in many studies because it has close relation with anesthetic morbidity and mortality. This classification was performed on 243 canine patients undergoing surgical procedures at the Veterinary Teaching Hospital. The results obtained were as follows: ASA I (38, 15.64%), ASA II (53; 21.81%), ASA II Emergency (E) (2; 0.82%), ASA III (78; 32.10%), ASA III E (23; 9.46%), ASA IV (11; 4.53 %), ASA IV E (36; 14.81%), and ASA V (2; 0.82%). Most patients were ASA III (moderate systemic disease), demonstrating that in the analyzed service the most operated animals are carriers of disease. The mortality rate was 2.46%, with most deaths occurring postoperatively and in patients with an emergency. The greatest risks are related to patients with more severe categories of the classification ASA, in emergency surgery, and especially in the postoperative period.(AU)

Method Cross-sectional descriptive study with 491 patients undergoing elective surgery, treated at APA/HUGG Clinic from March to December 2014. The following variables were assessed: sex, age, BMI, smoking status, associated diseases, classification of MET's and ASA, presence of decompensated disease, medical associated appointments interconsultation, specialty and surgical risk, history of prior anesthetic-surgical procedure, and complications. Results There was a predominance of female (64.8%) and overweight patients (55.9%), aged 18-59 years. The prevalence of associated diseases was high (71.3%), with hypertension pressure prevailing (50.1%). Most patients had clinically compensated morbidity (96.3%) and long-term use of medication (77.4%). Regarding the surgical characteristics, the most frequent specialty was general and medium risk surgeries. The analysis of the characteristics by age showed that the elderly have more associated diseases and long-term use of medication, in addition to predominance of ASA II-III. Conclusion The epidemiological profile of surgical patients seen at the APA/HUGG was female, age 18-59 years, overweight, with associated diseases, long-term use of medication, without clinical decompensation, ASA II and MET's ≥4. Knowledge of the clinical characteristics of surgical patients is critical to schedule the perioperative care, allowing the improvement of quality and safety in anesthesia and surgery.

Effects of preanesthetic dexmedetomidine on hemodynamic responses to endotracheal intubation in elderly patients undergoing treatment for hypertension: a randomized, double-blinded trial / 대한마취과학회지

BACKGROUND: Dexmedetomidine is an alpha-2 adrenergic agonist with sedative, anxiolytic, and analgesic properties. This study was designed to evaluate the inhibitory effects of preoperative administration of 0.5 µg/kg dexmedetomidine on hemodynamic responses caused by endotracheal intubation in elderly patients undergoing treatment for hypertension. METHODS: Forty elderly (≥ 65 years old) patients who had been receiving hypertension treatment, had American Society of Anesthesiologists physical status II, and were scheduled to undergo elective noncardiac surgery were randomly selected and assigned to 2 groups. Group C received normal saline and group D received 0.5 µg/kg dexmedetomidine intravenously over 10 min just before endotracheal intubation. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR) were recorded preoperatively in the ward, immediately after study drug administration, and at 1, 3, and 5 min after endotracheal intubation. RESULTS: Compared to group C, group D showed significantly lower SBP and MAP at 1, 3, and 5 min as well as significantly lower DBP and HR at 3 and 5 min after endotracheal intubation. CONCLUSIONS: In elderly patients receiving hypertension treatment, a single preanesthetic dose of dexmedetomidine (0.5 µg/kg) effectively suppressed the hemodynamic responses to endotracheal intubation.

A avaliação pré-anestésica para cirurgia oftalmológica em idosos é realmente necessária? A realidade de um hospital público / The pre-anesthetic evaluation for ophthalmic surgery in the elderly is really necessary? The reality of a public hospital

RESUMO Objetivos: A avaliação pré-anestésica (APA) e a realização de exames laboratoriais são questionadas para cirurgias oftalmológicas ambulatoriais por acrescentarem custos e retardarem a cirurgia. Estas são de baixo risco, mas os pacientes são idosos e com várias comorbidades. O objetivo deste estudo foi determinar se a APA é realmente necessária nestes pacientes em um hospital público. Métodos: Foi conduzido um estudo retrospectivo em 297 prontuários contendo a APA de pacientes para cirurgias oftalmológicas em um hospital público. Foram avaliados através da história, exame clínico e exames complementares, a proporção de pacientes que apresentaram na APA doenças desconhecidas ou não controladas e alterações dos exames complementares. Resultados: A média de idade dos pacientes foi de 71,5 anos, com 95,28% tendo pelo menos uma doença crônica. A doença mais prevalente foi hipertensão arterial sistêmica (62,96%), que em 7,7% dos pacientes estavam sem controle adequado; 2.3% não tinham diagnóstico de HAS. O diabetes mellitus tipo 2 apareceu em segundo (22,22%), com 5,3% sem controle adequado. Glicemia acima de 100 mg.dl-1 foi encontrada em 25,92%, sem diagnóstico conhecido. Do total, 84,8% tomavam pelo menos um medicamento. Somente 73,4% dos pacientes foram liberados para a cirurgia na primeira consulta. Conclusão: A APA em oftalmologia é capaz de detectar doenças não diagnosticadas, ou condições clínicas instáveis, e exerce um papel não só de otimização do paciente para a cirurgia como de atendimento primário, desempenhando papel importante na saúde global da população e, portanto, considerada necessária nos pacientes idosos do sistema público de saúde.

ABSTRACT Objectives: Pre-anesthetic assessment (PAA) and laboratory tests are questioned for ophthalmic procedures due to their additional costs and surgery delays. These are lower risks, nonetheless, patients are elderly and suffer from multiple comorbidities. The aim of this study was to determinate if it is really necessary in a public hospital. Method: a retrospective study on 297 medical records containing the pre-anesthetic questionary from ophthalmic surgery patients in a public hospital was leaded. By the anamnesis, clinical examination and laboratory tests, the rate of patients who came up with unknown or uncontrolled diseases for the pre-anesthetic evaluation among with unsettled lab tests were analyzed. Results: The patients's mean age was 71.5 years old. 95.28% of them suffer from at least one chronic disease. The most prevailer illness was systemic arterial hypertension (SAH) (62.96%), which in 7.7% of were uncontroled. Also 2.3% had no diagnosis of SAH. The DM2 appeared in second (22.22%), with 5.3% without proper management. Glycaemia above 100 mg.dl1 was found in 25.92%, undiagnosed; 84.8% of the total were taking at least one medication. Only 73.4% of patients were released for surgery in the first moment. Discussion: To sum up, PAA in ophthalmology surgery is able to bring up undiagnosed diseases, or unstable medical conditions, and it plays a role not only in optimize the patient for surgery, but also as primary care. It can be an important deal to improve population's health, therefore, considered necessary in elderly patients in the public health system.

Analysis of pre-operative aspartate aminotransferase and alanine aminotransferase in 14,185 pediatric patients

BACKGROUND: The aim of this study was to investigate the efficacy of routine pre-anesthetic aspartate aminotransferase (AST) and alanine aminotransferase (ALT) tests for detection of hepatic abnormalities and usefulness in perioperative management. METHODS: The laboratory findings of 14,185 pediatric patients younger than 18 years from October 2004 to December 2010 were investigated by retrospective review of medical records. All of the patients had undergone preoperative AST and ALT screening. RESULTS: Among the 14,185 patients, 221 patients experienced elevation of both AST and ALT. However, only 21 patients were suspicious for hepatic disease defined as persistent elevation of AST and ALT preoperatively. Among the 221 patients with elevation of both AST and ALT, 20 patients were examined by additional abdominal ultrasonography and hepatic abnormalities were detected in 13 of these patients (65%) and 40 patients were consulted to the department of pediatrics or internal medicine. CONCLUSIONS: In this single-center, retrograde study, the usefulness of preoperative routine AST and ALT testing was shown to be limited for detection of hepatic abnormalities in pediatric patients undergoing general anesthesia. Further multi-center, large-scale investigation would be required.

Recent knowledge of preoperative evaluation and preanesthetic management in infants

Preoperative assessment and optimization of a patient's condition are important components of anesthesia practice. Improvements in evaluation and management can potentially reduce adverse events, improve patient and caregiver satisfaction, and reduce costs. Although routine preoperative laboratory tests are ordered in many institutions, history taking and physical examination provide more information about patients than laboratory tests do. Therefore, history taking and physical examination should be used to direct test ordering, and a test should be ordered only if the results will impact the decision to proceed with the planned procedure or alter the care plans. Preoperative laboratory tests without specific indications lack clinical usefulness and may actually lead to patient injury because of unnecessary interventions, delay of surgery, anxiety, and even inappropriate therapies. After sufficient discussion between anesthesiologists and surgeons in each institution, diagnostic testing guidelines for the preoperative evaluation should be developed to improve patient care, standardize clinical practice, improve efficiency, and reduce costs. For preoperative management for infants, preoperative evaluation is similar to that for the adult, but reducing anxiety of patients and their parents is especially important. Although many nonpharmacologic methods are used to reduce anxiety, the pharmacologic methods are more effective than nonparmacologic methods. The administration of sedative premedication to infants who are about to undergo anesthesia and surgery can result in beneficial effects during the preoperative and postoperative periods by decreasing anxiety, increasing cooperation during anesthesia induction, and reducing negative postoperative behavioral responses.

Medications or food before anesthesia to note taking

Decisions about stopping or continuing medications perioperatively should be based on withdrawal potential, the potential for disease progression if therapy is interrupted, and the potential for drug interactions with anesthesia. In general, most medications are tolerated well through surgery and do not interfere with anesthetic administration. Therefore, most drugs should be continued through the morning of surgery. However, some medications are known to influence surgical risk or surgical decisions (e.g., antiplatelet agents, anticoagulants, some hormonal therapies, and herbal remedies), so it is important to obtain a complete medication list from the patient and to advise adjusting doses or discontinuing certain potentially complicating medications in advance of surgery. This article reviews general recommendations for perioperative management of a number of common medication classes.
