RESUMO

OBJECTIVES/HYPOTHESIS: Patients' eligibility for bilateral selective laryngeal reinnervation surgery is evaluated by suspension microlaryngoscopy (SML) examination with laryngeal electromyography (LEMG). Maintaining spontaneous ventilation, with remifentanil sedation/analgesia without endotracheal tube, to allow the patient to phonate with the surgeon during awake, LEMG is a major challenge for the anesthesiologist and the otorhinololaryngologist. The objective of this study was to evaluate the safety and efficacy of a novel anesthesia protocol to manage airway access during awake tubeless SML. STUDY DESIGN: Retrospective study. METHODS: Anesthesia records of patients undergoing awake SML with LEMG were retrospectively analyzed. Procedures were performed with remifentanil sedation/analgesia with targeted controlled infusion (TCI) in combination with local anesthesia. The main outcome was the failure rate of the anesthesia protocol during the procedure. Secondary outcomes were as follows: rate of apnea requiring ventilation, airway bleeding, regurgitation, hemodynamic data as well as vasopressor use, complications, and surgeon satisfaction with the procedure. RESULTS: Data were obtained for 39 patients between November 2017 and September 2019, the mean age was 52 years and 29 (74%) were female. All procedures were completed without complications (0% [0-9]). Three patients (8% [1.6-20.8]) had an intraoperative episode of hypoxemia requiring mask reventilation. There was no airway bleeding, no regurgitation, and no hypotensive episode. Three patients (8% [1.6-20.8]) had noninvasive ventilation for respiratory distress after the end of the procedure. CONCLUSIONS: Our results show that awake tubeless SML allowing phonation during LEMG can be realized under sedation and local anesthesia. However, further data are needed concerning the intraoperative and postoperative safety of the procedure. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2669-E2675, 2021.

RESUMO

Abstract Background and objectives Preoperative use of flurbiprofen axetil (FA) is extensively adopted to modulate the effects of analgesia. However, the relationship between FA and sedation agents remains unclear. In this study, we aimed to investigate the effects of different doses of FA on the median Effective Concentration (EC50) of propofol. Methods Ninety-six patients (ASA I or II, aged 18-65 years) were randomly assigned into one of four groups in a 1:1:1:1 ratio. Group A (control group) received 10 mL of Intralipid, and groups B, C and D received 0.5 mg.kg−1, 0.75 mg.kg−1 and 1 mg.kg−1 of FA, respectively, 10 minutes before induction. The depth of anesthesia was measured by the Bispectral Index (BIS). The "up-and-down" method was used to calculate the EC50 of propofol. During the equilibration period, if BIS ≤ 50 (or BIS > 50), the next patient would receive a 0.5 µg.mL−1-lower (or -higher) propofol Target-Controlled Infusion (TCI) concentration. The hemodynamic data were recorded at baseline, 10 minutes after FA administration, after induction, after intubation and 15 minutes after intubation. Results The EC50 of propofol was lower in Group C (2.32 µg.mL−1, 95% Confidence Interval [95% CI] 1.85-2.75) and D (2.39 µg.mL−1, 95% CI 1.91-2.67) than in Group A (2.96 µg.mL−1, 95% CI 2.55-3.33) (p = 0.023, p = 0.048, respectively). There were no significant differences in the EC50 between Group B (2.53 µg.mL−1, 95% CI 2.33-2.71) and Group A (p > 0.05). There were no significant differences in Heart Rate (HR) among groups A, B and C. The HR was significantly lower in Group D than in Group A after intubation (66 ± 6 vs. 80 ± 10 bpm, p < 0.01) and 15 minutes after intubation (61 ± 4 vs. 70 ± 8 bpm, p < 0.01). There were no significant differences among the four groups in Mean Arterial Pressure (MAP) at any time point. The MAP of the four groups was significantly lower after induction, after intubation, and 15 minutes after intubation than at baseline (p < 0.05). Conclusion High-dose FA (0.75 mg.kg−1 or 1 mg.kg−1) reduces the EC50 of propofol, and 1 mg.kg−1 FA reduces the HR for adequate anesthesia in unstimulated patients. Although this result should be investigated in cases of surgical stimulation, we suggest that FA pre-administration may reduce the propofol requirement when the depth of anesthesia is measured by BIS.


Resumo Justificativa e objetivos A administração pré‐operatória de Flurbiprofeno Axetil (FA) é amplamente usada para a modulação da analgesia. No entanto, a relação entre FA e fármacos sedativos permanece obscura. Neste estudo, nosso objetivo foi investigar os efeitos de diferentes doses de FA na Concentração Efetiva mediana (CE50) do propofol. Métodos Noventa e seis pacientes (ASA I ou II, com idades de 18-65 anos) foram alocados aleatoriamente em quatro grupos na proporção de 1:1:1:1. Dez minutos antes da indução, o Grupo A (grupo controle) recebeu 10 mL de Intralipid, enquanto os grupos B, C e D receberam FA na dose de 0,5 mg.kg‐1; 0,75 mg.kg‐1 e 1 mg.kg‐1, respectivamente. A profundidade da anestesia foi medida pelo Índice Bispectral (BIS). O método up‐and‐down foi usado para calcular a CE50 do propofol. Durante o período de equilíbrio, se o valor do BIS fosse ≤ 50 ou BIS > 50, o próximo paciente tinha a infusão de propofol ajustada para uma concentração alvo‐controlada 0,5 µg.mL‐1 inferior ou superior, respectivamente. Os dados hemodinâmicos foram registrados no início do estudo, 10 minutos após a administração de FA, após a indução, após a intubação e 15 minutos após a intubação. Resultados A CE50 do propofol foi menor no Grupo C (2,32 µg.mL‐1, Intervalo de Confiança de 95% [95% IC] 1,85-2,75) e D (2,39 µg.mL‐1, 95% IC 1,91-2,67) do que no Grupo A (2,96 µg.mL‐1; 95% IC 2,55-3,33) (p = 0,023, p = 0,048, respectivamente). Não houve diferenças significantes na CE50 entre o Grupo B (2,53 µg.mL‐1, 95% IC 2,33-2,71) e o Grupo A (p > 0,05). Não houve diferenças significantes na Frequência Cardíaca (FC) entre os grupos A, B e C. A FC foi significantemente menor no grupo D do que no grupo A após a intubação (66 ± 6 vs. 80 ± 10 bpm, p < 0,01) e 15 minutos após a intubação (61 ± 4 vs. 70 ± 8 bpm, p < 0,01). Não houve diferenças significantes entre os quatro grupos na Pressão Arterial Média (PAM) em qualquer momento. A PAM dos quatro grupos foi significantemente menor após a indução, após a intubação e 15 minutos após a intubação do que na linha de base (p < 0,05). Conclusão FA em altas doses (0,75 mg.kg‐1 ou 1 mg.kg‐1) reduz a CE50 do propofol, e 1 mg.kg‐1 de FA reduz a FC durante níveis adequados de anestesia em pacientes não estimulados. Embora esse resultado deva ser investigado na presença de estimulação cirúrgica, sugerimos que a pré‐administração de FA pode reduzir a necessidade de propofol durante anestesia cuja profundidade seja monitorada pelo BIS.

RESUMO

Transcatheter aortic valve implantation (TAVI) using a transfemoral approach under local anesthesia with conscious sedation (LACS) is becoming an increasingly common TAVI strategy. However, patients who are awake during the TAVI procedure can experience stress, anxiety, and pain, even when LACS is used. Clinical hypnotherapy is an anxiolytic intervention that can be beneficial for patients undergoing invasive surgery. This study aimed to assess the perioperative outcomes of adjunctive hypnotherapy undergoing transfemoral TAVI with LACS.Consecutive patients (n = 143) with symptomatic severe aortic stenosis who underwent transfemoral TAVI with LACS only (n = 107) or with LACS and hypnotherapy (n = 36) between January 2015 and April 2016 were retrospectively included in the study. The clinical outcomes were compared between the two groups. The LACS with hypnotherapy group had a significantly shorter length of stay in the intensive care unit (ICU; LACS only versus LACS with hypnotherapy: 4.0 (4.0-5.5) days versus 3.0 (3.0-5.0) days, P < 0.01). Moreover, the use of anesthetics (propofol and remifentanil) and norepinephrine was significantly lower in the LACS with hypnotherapy group (e.g., for propofol, LACS only versus LACS with hypnotherapy: 96.4 ± 104.7 mg versus 15.0 ± 31.8 mg, P < 0.001). The multiple regression analysis showed that being male, hypnotherapy, and the composite complication score were independently associated with the length of stay in the ICU.The adjunctive hypnotherapy on LACS among transfemoral TAVI patients may facilitate perioperative management. However, a prospective randomized study is necessary to confirm the efficacy of hypnotherapy among TAVI patients.

RESUMO

BACKGROUND: The aepEXplus monitoring system, which uses mid-latency auditory evoked potentials to measure depth of hypnosis, was evaluated in pediatric patients receiving desflurane-remifentanil anesthesia. METHODS: Seventy-five patients, 1-18 years of age (stratified for age; 1-3, 3-6, 6-18 years, for subgroup analyses), were included in this prospective observational study. The aepEX and the bispectral index (BIS) were recorded simultaneously, the latter serving as a reference. The ability of the aepEX to detect different levels of consciousness, defined according to the University of Michigan Sedation Scale, investigated using prediction probability (Pk), and receiver operating characteristic (ROC) analysis, served as the primary outcome parameter. As a secondary outcome parameter, the relationship between end-tidal desflurane and the aepEX and BIS values were calculated by fitting in a nonlinear regression model. RESULTS: The Pk values for the aepEX and the BIS were, respectively, .68 (95% CI, 0.53-0.82) and .85 (95% CI, 0.73-0.96; P = .02). The aepEX and the BIS had an area under the ROC curve of, respectively, 0.89 (95% CI, 0.80-0.95) and 0.76 (95% CI, 0.68-0.84; P = .04). The maximized sensitivity and specificity were, respectively, 81% (95% CI, 61%-93%) and 86% (95% CI, 74%-94%) for the aepEX at a cutoff value of >52, and 69% (95% CI, 56%-81%) and 70% (95% CI, 57%-81%) for the BIS at a cutoff value of >65. The age-corrected end-tidal desflurane concentration associated with an index value of 50 (EC50) was 0.59 minimum alveolar concentration (interquartile range: 0.38-0.85) and 0.58 minimum alveolar concentration (interquartile range: 0.41-0.70) for, respectively, the aepEX and BIS (P = .69). Age-group analysis showed no evidence of a difference regarding the area under the ROC curve or EC50. CONCLUSIONS: The aepEX can reliably differentiate between a conscious and an unconscious state in pediatric patients receiving desflurane-remifentanil anesthesia.

RESUMO

Background/aim: To examine the effects of active and passive smoking on perioperative anesthetic and analgesic consumption. Materials and methods: Patients were divided into three groups: group S, smokers; group PS, passive smokers; and group NS, individuals who did not have a history of smoking and were not exposed to smoke. All patients underwent the standard total intravenous anesthesia method. The primary endpoint of this study was determination of the total amount of propofol and remifentanil consumed. Results: The amount of propofol used in induction of anesthesia was significantly higher in group S compared to groups PS and NS. Moreover, the total consumption of propofol was significantly higher in group S compared to groups PS and NS. The total propofol consumption of group PS was significantly higher than that of group NS (P = 0.00). Analysis of total remifentanil consumption showed that remifentanil use was significantly higher in group S compared to group NS (P = 0.00). Conclusion: The amount of the anesthetic required to ensure equal anesthetic depth in similar surgeries was higher in active smokers and passive smokers compared to nonsmokers.

RESUMO

CONTEXT: One of the most common complications of a Caesarean section (C-section) is postoperative inflammation as well as operative and postoperative pain associated with the surgery. The control and mitigation of pain after surgery is the main goal of anesthesiologists. OBJECTIVES: This study aimed to compare the effects of intravenous apotel and remifentanil on postoperative pain control in women undergoing an elective C-section. DESIGN: The research team designed a single-blinded, randomized clinical trial. SETTING: The study was performed at the Taleghani Hospital (Arak, Iran). PARTICIPANTS: Potential participants were 70 patients undergoing an elective C-section. INTERVENTION: Participants were divided randomly into 2 groups, the apotel (A) and remifentanil (R) groups, with 35 participants in each group. The participants in the A group received an infusion of 1 g of apotel to 200 cc of normal saline for 20 min, after anesthesia, the removal of their fetuses, and the clamping of their umbilical cords. The same procedure was followed for the R group (ie, the participants received an infusion of 0.5 µg of remifentanil per kg of body weight per minute after anesthesia), removal of their fetuses, and clamping of their umbilical cords. OUTCOME MEASURES: Pain scores were measured 3 times using a visual analogue scale during the recovery period (from anesthesia and pain scores) and at 4 and 12 h after surgery after surgery. Participants' use of narcotics during the 24 h after surgery was recorded. Data analysis was done using SPSS (version 16) statistical software. RESULTS: The pain scores of the R group were lower than those of the A group during the recovery period and a statistically significant difference existed between the pain scores of the 2 groups during that period (P = .01). No statistically significant difference existed between the groups in participants' mean use of narcotic drugs during the 24 h of surgery. Moreover, no statistically significant differences were found between the groups in participants' blood pressures or heart rates during the recovery period or at 4 and 12 h after surgery (P ≥ .05). CONCLUSION: Remifentanil can provide better postoperative pain control than apotel immediately after surgery.

RESUMO

Transcutaneous electrical acupoint stimulation (TEAS) is a emerging treatment which combines transcutaneous electrical nerve stimulation with traditional acupoint therapy. The present study was aimed to evaluate the effect of TEAS on the effective concentration (EC50) of remifentanil suppressing tracheal extubation response in elderly patients.Fifty-three patients undergoing spine surgery were randomly divided into 2 groups: control group (group C, n = 26) and transcutaneous electrical acupoint stimulation group (group TEAS, n = 27). The EC50 values for remifentanil TCI were determined using sequential method and probit analysis.The remifentanil EC50 of that suppressed responses to extubation during anesthetic emergence was 1.20 ng/mL in group TEAS, a value that was significantly lower than the 1.64 ng/mL needed by patients in group C.The TEAS can enhance the efficacy of remifentanil on suppressing responses to tracheal extubation in elderly patients, the EC50 of remifentanil can reduce approximately 27% compared with group C.

RESUMO

Abstract Background and objectives: The conscious patient cooperation during neurological procedures has become necessary for the delimitation of areas to be managed by a neurosurgeon, with better results in the treatment of tumor lesions, vascular or epileptic foci, and lesser sequelae. The need for perioperative awareness (responsiveness to commands) challenges anesthesiologists to further ensure patient safety during the procedure. Several techniques have been described for this purpose. Case report: In this case, interaction with the patient during brain tumor resection enabled a broad approach of the tumor lesion, limited by deficits in speech and naming observed during surgical manipulation, avoiding major consequences. The chosen technique was deepening of general anesthesia during surgical times of most painful stimulus with intraoperative awakening of the patient. Conclusions: Patient selection, an exhaustive explanation of the procedure to him, and the selection of drugs are crucial for a successful procedure. Laryngeal mask is useful in times requiring greater depth and anesthetic ventilation control, primarily in situations where endotracheal intubation may be hindered by the position. The continuous infusion of remifentanil and adjuncts in the awake period associated adequate analgesia and full consciousness.


Resumo Justificativa e objetivos: A colaboração consciente do paciente durante procedimentos neurológicos tem se tornado necessária para delimitar áreas a serem abordadas pelo neurocirurgião, com melhores resultados no tratamento de lesões tumorais, vasculares ou focos epiléticos e minimização de sequelas. A necessidade de consciência perioperatória e responsividade a comandos desafia o anestesiologista a garantir ainda a segurança do paciente durante o procedimento. Várias técnicas têm sido descritas para esse fim. Relato de caso: No presente caso, a interação com paciente durante ressecção de tumor cerebral possibilitou abordagem ampla de lesão tumoral, limitada por déficits de fala e de identificação notados à manipulação cirúrgica, e evitou sequelas maiores. A indução de anestesia geral em tempos cirúrgicos de maior estímulo doloroso com despertar intraoperatório do paciente foi a técnica escolhida. Conclusões: A seleção do paciente, seu exaustivo esclarecimento e a seleção das drogas são de fundamental importância para o sucesso do procedimento. A máscara laríngea é instrumento útil em tempos que exigem maior profundidade anestésica e controle da ventilação, primariamente em situações em que a intubação endotraqueal pode estar dificultada pelo posicionamento. A infusão contínua de remifentanil e coadjuvantes no período desperto associou analgesia adequada e consciência plena.

RESUMO

INTRODUCTION: Healthcare associated infections (HAI) are the most frequent complication of hospitalized patients. The aim of this study was to describe the clinical and epidemiological characteristics of critically ill post-surgical patients with a diagnosis of healthcare associated infections, after a pattern of sedoanalgesia of at least 4 days. METHODS: All patients over 18 years of age with a unit admission of more than 4 days were consecutively selected. The study population was the one affected by surgical pathology where sedation was based as analgesic the opioid remifentanil for at least 96 hours in continuous perfusion. Patients who died during admission to the unit and those with combined analgesia (peripheral or neuroaxial blocks) were excluded. Data analysis was performed using the statistical package Stata version 7.0. RESULTS: The patients admitted to the Post-Surgical Critical Care Unit (PCU) during study were 1789 and the population eligible was comprised of 102 patients. 56.86% of patients suffered IACS. The most frequent IACS was pneumonia associated with mechanical ventilation (30.96 per 1000 days of mechanical ventilation), Pseudomonas aeruginosa being the most frequently isolated germ. The germs with the greatest involvement in multiple drug resistance (MDROs) were enterobacteria, mainly Klebsiella pneumoniae resistant to extended-spectrum beta-lactamases (ESBL). CONCLUSIONS: Pneumonia associated with mechanical ventilation is the most prevalent HAI and Pseudomonas aeruginosa is the main etiological agent. The groups of antibiotics most frequently used were cephalosporin and aminoglycosides. It is necessary to implement the prevention strategies of the different HAI, since most of them are avoidable.
