Effect of recorded mother's voice on emergence delirium in pediatric patients: a systematic review with meta-analysis

Abstract Objective: Emergence delirium is a common complication in children. Recorded mother's voice, as a non-pharmacological measure, is increasingly used to prevent the emergence of delirium in pediatric patients, but sufficient evidence is still needed to prove its efficacy. Methods: Embase, PubMed, Cochrane Library, Web of Science, CINAHL, and Sinomed databases were searched for randomized controlled trials exploring the efficacy of recorded mother's voice in preventing the emergence of delirium in pediatric patients undergoing general anesthesia. The original data were pooled for the meta-analysis with Review Manager 5.4.1. This study was conducted based on the Cochrane Review Methods. Results: Eight studies with 724 children were included in the analysis. Recorded mother's voice reduced the incidence of emergence delirium when compared with either no voice (RR: 0.45; [95 % CI, 0.34 - 0.61]; p < 0.01; I2 = 7 %) or stranger's voice (RR: 0.51; [95 % CI, 0.28 - 0.91]; p = 0.02; I2 = 38 %) without increasing other untoward reactions. In addition, it shortened the post-anesthesia care unit stay time when compared with no voice (MD = -5.64; [95 % CI, -8.43 to -2.58]; p < 0.01, I2 = 0 %), but not stranger's voice (MD = -1.23; [95 % CI, -3.08 to 0.63]; p = 0.19, I2 = 0 %). It also shortened the extubation time and reduced the incidence of postoperative rescue analgesia. Conclusion: The current analysis indicated that recorded mother's voices could reduce the incidence of emergency delirium, shorten post-anesthesia care unit stay time and extubation time, and decrease the incidence of postoperative rescue analgesia in children.

EVALUATION OF INTRAOPERATIVE PAIN OCCURRENCE AND NEED FOR SUPPLEMENTAL ANESTHESIA DURING EMERGENCY DENTAL CARE

Aims: This study aimed to evaluate the intraoperative pain (IOP) occurrence in situations of symptomatic irreversible pulpitis (SIP) and symptomatic apical periodontitis (SAP). Materials and Methods: Patients who sought emergency care presenting a diagnosis of SIP or SAP were included. IOP was measured with a Visual Analogue Scale (VAS) after five minutes of local anesthesia, during access to the pulp chamber, root canal exploration and at the end of procedures. In cases where pain was reported during treatment, supplementary anesthesia was performed. Pain scores were recorded and analyzed using a generalized estimating equation model with posthoc comparisons. Results: 56 patients were included. 35 had a diagnosis of SIP; and 21 a diagnosis of SAP. Mean preoperative pain scores for SAP and SIP were 6.69 (±1.54) and 6.39 (±1.48), respectively (p>0.05). In patients with SIP, significant differences were observed between: preoperative scores and other time points; scores after five minutes of local anesthesia and other time points; scores during pulp chamber access and at the end of procedures; and scores during root canal exploration and at the end of procedures (p<0.05). In patients with SAP, significant differences were observed between preoperative pain scores with all other time points (p<0.05). Chi-square test indicated an association between diagnosis and the need for supplementary anesthesia (p<0.05). Conclusions: In conclusion, there is a strong relationship between reduction of moderate/severe pain after application of local anesthesia. The need for supplemental anesthesia is significantly associated to the diagnosis of symptomatic irreversible pulpitis.

Anesthesia training: Are we doing enough in three years? Cross-sectional study

Introduction: The mínimum number of procedures required to be performed during anesthesia training has not been officially defined in Colombia. Although a number is no guarantee of acquired competencies, it does indicate the level of opportunity offered by the different programs. This study describes the practical training afforded to residents in a graduate anesthesia program in Colombia, and compares its results with international standards. Objective: Describe exposure to procedures performed by residents enrolled in a three-year anesthesia specialization program in Colombia between 2015 and 2020, and compare with the standards proposed by ASCOFAME and ACGME. Methods: Descriptive, cross-sectional study which included residents who did their specialization in a Colombian anesthesia program between 2015 and 2020. Complexity, anesthesia techniques, invasive monitoring and airway approach were described. Finally a descriptive comparison was made with the published references of the Colombian Association of Medical Schools (ASCOFAME) and the Accreditation Council for Graduate Medical Education (ACGME). Results: The results for 10 residents were included. Each resident had a median of 978 cases (IQR 942-1120), corresponding to 25 surgical specialties, the most frequent being general surgery (18%), orthopedics (16%), pediatric surgery (19%), and obstetrics (10.8%). According to the American Society of Anesthesiology (ASA) classification, the majority of patients were ASA II (39.63%) and ASA III (28.4%). Adequate exposure was achieved in 11 of the 15 categories proposed by ACGME and in 6 of the 15 proposed by ASCOFAME. Conclusions: A detailed description of the practice component acquired by the residents during their three years of training was obtained. This baseline provides insight into the national landscape and allows to describe the relationship with international standards.

The duration-dependent and sex-specific effects of neonatal sevoflurane exposure on cognitive function in rats

Clinical studies have found that neonatal sevoflurane exposure can increase the risk of cognitive dysfunction. However, recent studies have found that it can exhibit neuroprotective effects in some situations. In this study, we aimed to explore the effects of sevoflurane neonatal exposure in rats. A total of 144 rat pups (72 males and 72 females) were assigned to six groups and separately according to sevoflurane exposure of different times on the seventh day after birth. Blood gas analysis and western blot detection in the hippocampus were conducted after exposure. The Morris water maze test was conducted on the 32nd to 38th days after birth. The expression of PSD95 and synaptophysin in the hippocampus was detected after the Morris water maze test. We found that neonatal exposure to sevoflurane promoted apoptosis in the hippocampus, and Bax and caspase-3 were increased in a dose-dependent manner. The 2-h exposure had the greatest effects on cognitive dysfunction. However, with the extension of exposure time to 6 h, the effects on cognitive function were partly compensated. In addition, sevoflurane exposure decreased synaptogenesis in the hippocampus. However, as the exposure time was extended, the suppression of synaptogenesis was attenuated. In conclusion, neonatal sevoflurane exposure exhibited duration-dependent effects on cognitive function via Bax-caspase-3-dependent apoptosis and bidirectional effects on synaptogenesis in rats.

Metahemoglobinemia congénita. Reporte de caso / Congenital Methemoglobinemia. A Case Report

Resumen La metahemoglobinemia ocasionalmente causa cianosis, particularmente cuando es congénita. Debido a sus vías enzimáticas deficientes y a la disminución de la capacidad de transporte de oxígeno, para los pacientes con metahemoglobinemia congénita es importante evitar la exposición a agentes oxidantes. A continuación, presentamos un paciente pediátrico con metahemoglobinemia congénita no diagnosticada preoperatoriamente que fue sometido a cateterismo con diagnóstico probable de hipertensión pulmonar bajo anestesia general. El paciente pediátrico era un niño de 10 años que presentaba una lectura de oximetría de pulso (SpO2) 92% antes de la inducción de la anestesia. La metahemoglobinemia se sospechó intraoperatoriamente por primera vez debido a un desajuste de la SpO2 de la oximetría de pulso digital y la SaO2 (saturación arterial de oxígeno), y luego se confirmó mediante múltiples longitudes de onda con la CO-oximetría. Se discuten la fisiopatología, etiología, manifestaciones clínicas, consideraciones anestésicas y opciones de tratamiento de la metahemoglobinemia.

Abstract Methemoglobinemia occasionally causes cyanosis particularly in congenital methemoglobinemia. Avoidance of exposure to oxidizing agents is important for patients with congenital methemoglobinemia because of their deficient enzymatic pathways and decreased oxygen-carrying capacity. Here, we present a pediatric patient with preoperatively undiagnosed congenital methemoglobinemia who underwent catheterization with probably diagnosis of pulmonar hypertension under general anesthesia. The pediatric patient was a 10-year-old who displayed a low pulse oximetry reading of 92% prior to induction of anesthesia. Methemoglobinemia was first suspected intraoperatively because of a mismatch of SpO2 of finger pulse oximetry and SaO2 of arterial blood, and was later confirmed by multiplewavelength CO-oximetry. The pathophysiology, etiology, clinical manifestations, anesthetic considerations, and treatment options of methemoglobinemia are discussed.

Incidence and risk factors of post dural puncture headache after spinal anesthesia in Tripoli Hospitals

Post Dural Puncture Headache (PDPH) remains a prominent clinical concern to the present day and common complication seen in the field of anesthesiology and pain medicine. Identification of such risk factors is a crucial step in the rational modification of anesthetic practice and evaluation of therapeutic interventions. This study was conducted to demonstrate the incidence and risk factors of PDPH in patients after spinal Anesthesia during three days' post operations at general hospital in Tripoli, Libya. In this study certain factors related to patient history, baseline clinical state or anesthetic technique might be associated with an increased risk for this side effect, so it was collected historical, physiologic, and technical data to determine their association with PDPH. Out of total of 100 patients distributed over 5 different hospitals admitted over a period (from November 2020 to April 2021) 27% of them have a PDPH, while 92.5% of cases with PDPH are females, that 55.6% of PDPH cases are between 20 and 25 years old, and this percentage getting smaller as patients get older, most of the operations were caesarean section, at a rate of 58%, followed by lower abdominal surgeries with 19% of cases, and orthopedic surgeries with 17% of cases, while the lowest percentage was for the Urologic surgeries. 55% of cases with PDPH are classified as (case I), and 44% of them are classified as (case II), 81.5% of PDPH cases used noncutting needles. In this study the PDPH remains the most problem in hospitalized patients after spinal Anesthesia at Tripoli hospitals can be caused by variety of risk factors, associated with ASA physical states, nonprofessional technique, the females are more common than males and the percentage increasing in early age group

ObjectiveTo investigate risk factors for postoperative sore throat in patients with double-lumen endotracheal intubation. MethodsThe data used in this post-hoc analysis were prospectively collected from a randomized， controlled trial. Age from 18 to 65 years old， ASAI-Ⅲ patients undergoing general anesthesia with a double-lumen endotracheal tube were enrolled. The perioperative data collected retrospectively were as follows： gender， age， smoking history， endotracheal tube diameter， duration of endotracheal tube， dose of Sufentanil， use of Flurbiprofen Axetil， cough after extubation， etc..Dynamometer was applied to assess extubation force. According to occurrence of postoperative sore throat， patients were divided into two groups： those who experienced sore throats and those who did not. Comparative analysis and multivariate logistic regression analysis were performed to screen the risk factors. ROC curve was used for predicting the predictive value of risk factors. ResultsAmong the 163 patients ， 74 （45.4%） had postoperative sore throat vs 89 （54.6%） not had. Multivariate logistic regression showed female ［OR95%CI=3.83（1.73， 8.50）， P=0.000 1］ and extubation force ［OR95%CI=1.78（1.45， 2.17）， P＜0.001］ were independent risk factors for postoperative sore throat. AUC value showed the extubation force was 0.773［95%CI（0.701， 0.846）， P＜0.001］. Youden index was 0.447， and the cut-off valve of extubation force was 13N. ConclusionFemale and extubation force were risk factors for sore throat in patients with double lumen endotracheal intubation.

Application of Magnetic Resonance Imaging and Transrectal Ultrasound Image Fusion Targeted Transperineal Biopsy Technique Using Electromagnetic Needle Tracking Under Local Anaesthesia / 肿瘤防治研究

Objective To explore the effect and safety of magnetic resonance imaging and transrectal ultrasound (mpMRI-TRUS) image fusion targeted transperineal biopsy technique using electromagnetic needle tracking under local anesthesia. Methods We retrospectively analyzed the clinical and pathological data of 81 patients with mpMRI-TRUS image fusion targeted transperineal prostate biopsy using electromagnetic needle tracking under local anesthesia. Visual analog scale (VAS) and visual numeric scale (VNS) were used to evaluate the pain level and satisfaction of patients during prostate biopsy (VAS-1 and VNS-1), one hour after puncture (VAS-2 and VNS-2), and one day after surgery (VAS-3 and VNS-3). The perioperative clinical data and tumor positive rate of postoperative biopsy were recorded. Results The average prostate volume of 81 patients was 53.39±29.46 cm3. The PSA values of patients with PI-RADS scores of 2, 3, 4, and 5 were 9.14±2.31, 9.95±4.10, 14.77±6.36, and 32.17±24.39 ng/ml, respectively. The scores of VAS-1, VAS-2, and VAS-3 were 1.70±0.73, 1.16±0.58, and 0.53±0.55, respectively; the scores of VNS-1, VNS-2, and VNS-3 were 2.74±0.44, 3.69±0.46, and 3.84±0.37, respectively. The average surgical time was 17.47±3.44 minutes. Postoperative pathological results showed that the tumor positive rate of targeted prostate biopsy was 64.20%. According to the PI-RADS score for subgroup analysis, the tumor positive rates of patients with PI-RADS scores of 2, 3, 4, and 5 were 21.43%, 44.44%, 61.11%, and 96.77%, respectively. After transperineal prostate biopsy, gross hematuria occurred in 19.75% patients, and urinary retention occurred in 3.70%. The latter were relieved after symptomatic treatment. All patients did not experience complications, such as perineal puncture area hematoma, urinary tract infection, hematospermia, hematoma in perineal puncture area, urinary tract infection, hematospermia, vagus nerve reaction, or septic shock. Conclusion For suspected prostate cancer patients, mpMRI-TRUS image fusion targeted transperineal biopsy technique using electromagnetic needle tracking under local anesthesia is a feasible and easily tolerated surgical procedure. It has good safety and high tumor positive-detection rate, indicating that this technique is worthy of further clinical promotion and application.

ABSTRACT Objective: The main objective of this study was to compare stress and anxiety levels in children undergoing surgical procedures with or without parental presence at induction of anesthesia by measuring salivary cortisol levels and applying the mYPAS. Method: Quasi-randomized trial with children aged 5-12 year, with ASA physical status I, II, or III, undergoing elective surgery. According to parents' willingness, the pair were defined as accompanied or unaccompanied group. Chi-square, Fisher's exact tests, Student's t test, Mann-Whitney, Hodges-Lehman and Spearman's tests were used for statistical analyzes. Results: We included 46 children; 63% were preschool children mostly accompanied by their mothers (80%). The median mYPAS score was 37.5 (quartile range, 23.4-51.6) in unaccompanied children, and 55.0 (quartile range, 27.9-65.0) in accompanied children, with an estimated median difference of +11.8 (95% CI of 0 to 23.4; p = 0.044). There were no significant differences in the mean salivary cortisol levels. Conclusion: The level of anxiety was higher in accompanied children. There were no differences in salivary cortisol levels between both groups. Brazilian Registry of Clinical Trials (ReBEC):RBR-9wj4qvy.

Introducción: la gastrosquisis congénita (GC) es una patología con creciente demanda asistencial. Atentos a esto, en el Centro Hospitalario Pereira Rossell (CHPR) se implementó un protocolo de cuidados llevado adelante por un equipo multidisciplinario. En este trabajo nos proponemos evaluar el impacto en la sobrevida y morbilidad a partir de su aplicación. Material y método: estudio comparativo tipo antes y después de pacientes portadores de GC (n = 47), 29 de una cohorte histórica (GH) y 18 de una cohorte posaplicación de protocolo (GP). Con edad gestacional ≥ 36 semanas y peso al nacer ≥ 2500 g, asistidos en el CHPR entre los años 2016 y 2021. Resultados: no se observaron diferencias perinatales entre ambos grupos, ni en la incidencia de GQ complicadas. En el GP se observó mayor incidencia de cierre abdominal precoz (p < 0,01), menor necesidad de realización de silo quirúrgico (p < 0,01), menor tiempo de administración de ventilación mecánica (p = 0,03), de uso total de opioides (p < 0,01), de administración de nutrición parenteral (p = 0,03), e inicio más temprano de la alimentación enteral (p = 0,03). Sin diferencias en la sobrevida al egreso hospitalario. Conclusiones: la aplicación de un protocolo estandarizado se asoció a una reducción significativa en el tiempo de cierre abdominal, de ventilación mecánica, nutrición parenteral y de opioides, con inicio más precoz de la nutrición enteral.

Summary: Introduction: congenital gastroschisis is an increasingly demanded pathology, therefore a care protocol was implemented at the Pereira Rossell Pediatric Hospital (CHPR), and it has been carried out by a multidisciplinary team. In this paper, we aim at assessing the morbidity and mortality impact of survival and morbidity of this application. Materials and Methods: comparative before and after study of a historical cohort (GH, n=29) versus a post-protocol application cohort (GP, n=18), in patients with a gestational age ≥36 weeks and birth weight ≥2500 grams assisted in CHPR between 2016-2021. Results: no perinatal differences were observed between both groups or in the incidence of complicated GQ. In the GP, a higher incidence of early abdominal closure was decreased (GH 3.4% vs GP 67%, p<0.01), less need to perform a surgical silo (GH 100% vs GP 33%, p<0.01 ), shorter mechanical ventilation administration time (GH 2 days vs GP 0.5 days, p=0.03), total use of opioids (GH 3.5 days vs GP 7 days, p<0.01) , of administration of parenteral nutrition (GH 24.5 days vs GP 20 days, p=0.03), and earlier start of enteral feeding (GH 11 days vs GP 7 days, p=0.03). No differences in survival after hospital discharge (93% vs 89%, p=0.63). Conclusions: the application of a standardized protocol was linked to a significant reduction in the time of abdominal closure, mechanical ventilation, parenteral nutrition, and opioids, with earlier initiation of enteral nutrition.

General anesthesia versus conscious sedation in mechanical thrombectomy for patients with acute ischemic stroke: systematic review and meta-analysis / Anestesia geral versus sedação consciente na trombectomia mecânica para pacientes com AVC isquêmico agudo: revisão sistemática e metanálise

Abstract Background After recently published randomized clinical trials, the choice of the best anesthetic procedure for mechanical thrombectomy (MT) in acute ischemic stroke (AIS) due to large vessel occlusion (LVO) is not definite. Objective To compare the efficacy and safety of general anesthesia (GA) versus conscious sedation (CS) in patients with AIS who underwent MT, explicitly focusing on procedural and clinical outcomes and the incidence of adverse events. Methods PubMed, Embase, and Cochrane were systematically searched for randomized controlled trials (RCTs) comparing GA versus CS in patients who underwent MT due to LVO-AIS. Odds ratios (ORs) were calculated for binary outcomes, with 95% confidence intervals (CIs). Random effects models were used for all outcomes. Heterogeneity was assessed with I2 statistics. Results Eight RCTs (1,300 patients) were included, of whom 650 (50%) underwent GA. Recanalization success was significantly higher in the GA group (OR 1.68; 95% CI 1.26-2.24; p < 0.04) than in CS. No significant difference between groups were found for good functional recovery (OR 1.13; IC 95% 0.76-1.67; p = 0.56), incidence of pneumonia (OR 1.23; IC 95% 0.56- 2,69; p = 0.61), three-month mortality (OR 0.99; IC 95% 0.73-1.34; p = 0.95), or cerebral hemorrhage (OR 0.97; IC 95% 0.68-1.38; p = 0.88). Conclusion Despite the increase in recanalization success rates in the GA group, GA and CS show similar rates of good functional recovery, three-month mortality, incidence of pneumonia, and cerebral hemorrhage in patients undergoing MT.

Resumo Antecedentes A trombectomia mecânica (TM) é o padrão de tratamento para pacientes com acidente vascular cerebral isquêmico agudo (AVCI) devido à oclusão de grandes vasos (OGV). No entanto, ainda não está claro qual é o procedimento anestésico mais benéfico para a TM. Objetivo Nosso objetivo foi comparar a eficácia e a segurança da anestesia geral (AG) versus sedação consciente (SC) em pacientes com AVCI submetidos à TM, focando especificamente nos resultados procedimentais e clínicos, bem como na incidência de eventos adversos. Métodos Foram realizadas buscas sistemáticas nas bases PubMed, Embase e Cochrane por ensaios clínicos randomizados (ECRs) comparando AG versus SC em pacientes submetidos à TM devido a AVCI por OGV. Razões de chances (ORs) foram calculadas para desfechos binários, com intervalos de confiança de 95% (ICs). Modelos de efeitos aleatórios foram usados para todos os resultados.

Comparison of the effect of adding midazolam versus fentanyl to intrathecal levobupivacaine in patients undergoing cesarean section: double-blind, randomized clinical trial

Abstract Background: Many adjuvants are added to prolong the effects of spinal analgesia. We investigated the postoperative analgesic efficacy of the addition of midazolam or fentanyl to intrathe-cal levobupivacaine in women undergoing cesarean delivery. Methods: Eighty patients were randomly assigned to two groups (n = 40). Group M received 10 mg of 0.5% levobupivacaine plus 2 mg of midazolam. Group F received 10 mg of 0.5% levobupivacaine plus 25 μg of fentanyl. Assessments included motor and sensory block, APGAR score, time to first request for analgesia, postoperative pain score, total consumption of rescue analgesics, and adverse effects. Results: Sensory blockade was prolonged in Group M compared with Group F (215.58 ± 27.94 vs. 199.43 ± 19.77 min; p = 0.004), with no differences in other characteristics of the spinal block in intraoperative hemodynamics or APGAR score. The mean time to first request for rescue analgesia was longer in Group M (351.45 ± 11.05 min) than in Group F (268.83 ± 10.35 min; p = 0.000). The median total consumption of rescue analgesics in the first 24 hours postoperatively was 30 mg in Group M vs. 60 mg in Group F (p = 0.003). The median Visual Analog Scale (VAS) scores were lower in Group Ethan in Group F from the 8th to the 12th hour postoperatively, with no differences between the groups at other time points. The incidence of adverse effects was higher in Group F than in Group M. Conclusion: Intrathecal midazolam (2 mg) was superior to intrathecal fentanyl (25 μg) in increasing the duration of the sensory blockade and postoperative analgesia with lower postoperative pain scores and decreasing the incidence of adverse effects.

Influence of exogenous opioids on the acute inflammatory response in the perioperative period of oncological surgery: a clinical study

Abstract Background: Recently, opioids have been related to trigger changes in cytokine release and tumor angiogenesis processes, influencing tumor growth, metastasis, and recurrence. Methods: This is a prospective randomized clinical study to test whether if exogenous opioids used in the anesthesia during cancer surgery can affect the systemic inflammatory and immunological patterns. Patients were randomly allocated to the OP (opioid-inclusive) or OF (opioid-free) anesthesia group. A total of 45 patients were selected, being carriers of prostate, stomach, pancreas, bile ducts, breast, colon, lung, uterus, kidneys, or retroperitoneum tumors. Plasma levels of IL-4, IL-12, IL-17A, and TNF-α, and their oxidative stress profile before and after surgery were evaluated in both groups. In vitro tests were performed by using healthy donor blood incubated with each isolated drug used in patients' anesthesia for 1 hour, the same cytokines were measured in plasma. Results: There was a significant reduction in lipid peroxidation in both groups. Patients from OF group had a significant consumption of IL-12 in the perioperative period. The other cytokines evaluated did not vary. It was also observed a significant correlation between IL-12 and TNF-α levels in the OF-post group. Except for atracurium, all tested drugs led to a reduction in IL-12 levels. Conclusions: This study demonstrated that there is a reduction of IL-12 in the OF-post patients, suggesting acute consumption and that this seems to be a general mechanism of anesthetic drugs, as demonstrated in vitro. Also, these findings bring us to reflect if IL-12 changes may influence the disease progression and recurrence.

Recommendations from the Brazilian Society of Anesthesiology (SBA) for difficult airway management in pediatric care

Abstract Difficult airway management in pediatrics during anesthesia represents a major challenge, requiring a careful approach, advanced technical expertise, and accurate protocols. The task force of the Brazilian Society of Anesthesiology (SBA) presents a report containing updated recommendations for the management of difficult airways in children and neonates. These recommendations have been developed based on the consensus of a panel of experts, with the objective of offering strategies to overcome challenges during airway management in pediatric patients. Grounded in evidence published in international guidelines and expert opinions, the report highlights crucial steps for the appropriate management of difficult airways in pediatrics, encompassing assessment, preparation, positioning, pre-oxygenation, minimizing trauma, and, paramountly, the maintenance of arterial oxygenation. The report also delves into additional strategies involving the use of advanced tools, such as video laryngoscopy, flexible intubating bronchoscopy, and supraglottic devices. Emphasis is placed on the simplicity of implementing the outlined recommendations, with a focus on the significance of continuous education, training through realistic simulations, and familiarity with the latest available technologies. These practices are deemed essential to ensure procedural safety and contribute to the enhancement of anesthesia outcomes in pediatrics.

Hemodynamic impact of increasing time between fentanyl and propofol administration during anesthesia induction: a randomised, clinical trial

Abstract Background and objective: Anesthesia induction can produce severe propofol dose-dependent hypotension. Fentanyl coadministration reduces the catecholaminergic response to orotracheal intubation allowing propofol dose reduction. The aim of this study is to determine whether the hemodynamic response is improved by increasing the time between fentanyl and propofol administration and reducing the dose of the latter without increasing the time to achieve optimal hypnosis. Methods: After approval by the Research Ethics Committee, patients undergoing non-cardiac surgery with endotracheal intubation were randomized by a computer-generated table into six time-dose groups (1 or 2 minutes/1, 1.5, or 2mg.kg-1 of propofol). Patients with high bronchoaspiration risk, a difficult airway, hemodynamic instability, or anesthetic allergies were excluded. After giving intravenous fentanyl (2 μg.kg-1 ), each group received different doses of propofol after 1 or 2 minutes. Non-invasive blood pressure (BP) and heart rate (HR) were measured at pre-induction, pre-intubation, and post-intubation. Time to hypnosis (bispectral index < 60) was also recorded. Results: Of the 192 recruited patients, 186 completed the study (1 min group n = 94; 2 min group n = 92). It was observed that HR and BP decreased after propofol administration and increased after intubation in all groups (p<0.0001). In patients over 55 years, the 2 min - 2 mg.kg-1 group showed the greatest systolic BP reduction (36 ± 12%) at pre-intubation, while the 1 min - 1.5 mg.kg-1 group showed the least hemodynamic alteration between pre- and post-intubation (-4 ± 13%). No significant differences were found in younger patients or in the time to reach hypnosis between the six groups. While no cases of severe bradycardia were recorded, 5,4% of the sample required vasopressors. Conclusion: Increasing the time between the administration of fentanyl and propofol by up to two minutes results in greater hypotension in patients over 55 years.

Ultrasound-guided pericapsular nerve group and obturator nerve phenol neurolysis for refractory inpatient hip cancer metastasis pain: a case report

Abstract Introduction: Bone cancer metastasis may produce severe and refractory pain. It is often difficult to manage with systemic analgesics. Chemical neurolysis may be an effective alternative in terminally ill patients. Case report: Female terminally ill patient with hip metastasis of gastric cancer in severe pain. Neurolytic ultrasound-guided blocks of the pericapsular nerve group and obturator nerve were performed with 5% phenol. This led to satisfactory pain relief for 10 days, until the patient's death. Discussion: This approach may be effective and safe as an analgesic option for refractory hip pain due to metastasis or pathologic fracture in terminally ill patients.

Accuracy of closed-loop and open-loop propofol delivery systems by bispectral index monitoring in breast surgery patients: a prospective randomized trial

Abstract Background: This randomized and controlled prospective study tested the hypothesis that closed-loop Target-Controlled Infusion (TCI) of propofol would be associated with better system performance when compared with open-loop controlled delivery of propofol. Methods: Patients scheduled for elective breast surgery were randomly assigned to two groups: a closed-loop group, in which propofol infusion was performed by a closed-loop TCI system that used the Bispectral Index (BIS) as a feedback parameter to titrate the rate of propofol infusion, and an open-loop group, in which propofol infusion was performed manually and guided by the bispectral index. Results: A total of 156 patients were recruited for this study (closed-loop group n = 79; open-loop group n = 77). The Global Score (GS) of the closed-loop group was lower than that of the open-loop group (34.3 and 42.2) (p = 0.044). The proportions of time with a BIS value between 40 and 60 were almost identical in the closed-loop group and the open-loop group (68.7 ± 10.6% and 66.7 ± 13.3%) (p = 0.318). The individuals in the closed-loop group consumed more propofol compared with those in the open-loop group (7.20 ± 1.65 mg.kg−1.h−1 vs. 6.03 ± 1.31 mg.kg−1.h−1, p < 0.001). No intraoperative recall, somatic events or adverse events occurred. No significant difference in heart rate was observed between the two groups (p = 0.169). Conclusion: The closed-loop protocol was associated with lower BIS variability and lower out-of-range BIS values, at the cost of a greater consumption of propofol when compared to the open loop group.
