RESUMO
Abstract Introduction Spinal infusions of either fentanyl or sufentanil have been reported in international reports, articles, and scientific events worldwide. This study aimed to determine whether intrathecal fentanyl or sufentanil offers safety in mortality and perioperative adverse events. Methods MEDLINE (via PubMed), EMBASE, CENTRAL (Cochrane library databases), gray literature, hand-searching, and clinicaltrials.gov were systematically searched. Randomized controlled trials with no language, data, or status restrictions were included, comparing the effectiveness and safety of adding spinal lipophilic opioid to local anesthetics (LAs). Data were pooled using the random-effects models or fixed-effect models based on heterogeneity. Results The initial search retrieved 4469 records; 3241 records were eligible, and 3152 articles were excluded after reading titles and abstracts, with a high agreement rate (98.6%). After reading the full texts, 76 articles remained. Spinal fentanyl and sufentanil significantly reduced postoperative pain and opioid consumption, increased analgesia and pruritus. Fentanyl, but not sufentanil, significantly reduced both postoperative nausea and vomiting, and postoperative shivering; compared to LAs alone. The analyzed studies did not report any case of in-hospital mortality related to spinal lipophilic opioids. The rate of respiratory depression was 0.7% and 0.8% when spinal fentanyl or sufentanil was added and when it was not, respectively. Episodes of respiratory depression were rare, uneventful, occurred intraoperatively, and were easily manageable. Conclusion There is moderate to high quality certainty that there is evidence regarding the safety and effectiveness of adding lipophilic opioids to LAs in spinal anesthesia.

OBJECTIVE: Assess patients submitted to elective cesarean section under spinal anesthesia, and the efficacy of different doses of fentanyl associated with bupivacaine. METHODS: The study included 124 pregnant women randomly distributed into 4 groups (n = 31) according to different doses of fentanyl (15 µg, 10 µg, 7.5 µg), Groups I, II, and III, respectively, and control group IV, associated with 0.5% hyperbaric bupivacaine (10 mg). An epidural catheter was inserted in case epidural top-up was required. We assessed the anesthetic blockage characteristics, negative maternal and neonatal outcomes, and maternal side effects. Statistical analysis was performed using Kruskal-Wallis, Fisher's exact and chi-square tests. The level of significance was 5% (p < 0.05). RESULTS: The quality of analgesia, time for the first complaint of pain and motor block recovery time were significantly better for groups that received fentanyl in comparison to controls (p < 0.001). None of the groups had negative maternal-fetal outcomes. Nausea was significantly more frequent in patients in Groups II (10 µg) and III (7.5 µg) when compared to Groups I (15 µg) and IV (no fentanyl). Vomiting was more frequent in Group III than in Group I (p = 0.006). The incidence of pruritus was significantly higher in the groups receiving fentanyl (p = 0.012). CONCLUSIONS: Among the solutions studied, the spinal anesthesia technique using 15 µg of fentanyl associated with 10 mg of hyperbaric bupivacaine provided satisfactory analgesia and very low incidence of adverse effects for patients submitted to cesarean section.

Objetivo: Avaliar a associação entre as doses de fentanil utilizadas nos primeiros dez dias de vida de neonatos submetidos à correção cirúrgica de gastrosquise e as complicações respiratórias e gastrointestinais comumente associadas à essa faixa etária e defeito congênito. Métodos: O presente estudo avaliou de forma retrospectiva a coorte de recém-nascidos portadores de gastrosquise operados no IFF no período de janeiro de 2016 até junho de 2021. Dados demográficos dos neonatos e gestantes, das intervenções cirúrgicas, dos procedimentos anestésicos e dos cuidados perioperatórios em unidade de terapia intensiva neonatal foram coletados de prontuários. Os principais desfechos avaliados foram o tempo de intubação orotraqueal e de ventilação mecânica (IOT/VM), tempo de uso de NPT e data de início de dieta enteral. Foram descritos, tempo para dieta oral plena, tempo de internação em unidade de cuidados intensivos neonatais, diagnóstico de sepse, diagnóstico de apnéia, estridor, pneumonia e taxa de mortalidade. Nos primeiros dez dias de vida dos bebês, as doses de fentanil utilizadas no intraoperatório e periopratório, em bolus ou infusão contínua, foram quantificadas. Assim como, fez-se uma análise descritiva das abordagens cirúrgicas, das técnicas anestésicas e das complicações clínico-cirúrgicas apresentadas durante o período de internação na UTI. Por meio de modelagem estatística, o impacto do aumento das dose de fentanil sobre as complicações respiratórias e gastrointestinais foi avaliado. Resultados: No período do estudo 184 crianças receberam correção cirúrgica do defeito de parede no IFF e a taxa de mortalidade foi de 8,69%. Os dados de 176 neonatos foram coletados e 94% desses pacientes foram indentificadas como gastrosquise simples. Nossa coorte de 144 pacientes foi avaliada e os eventos mais frequentemente relacionados ao uso de maiores doses de fentanil foram aumento do tempo de ventilação mecânica, aumento do tempo total de uso de NPT e retardo para início da dieta enteral. Conclusão: O estudo mostrou piores desfechos respiratórios e gastrointestinais nos pacientes que receberam doses maiores de fentanil.
Objective: To evaluate the association between doses of fentanyl used in the first ten days of life in neonates undergoing surgical correction of gastroschisis and the respiratory and gastrointestinal complications commonly associated with this age group and congenital defect. Methods: This study evaluated retrospectively the cohort of newborns with gastroschisis operated at IFF between January 2016 and June 2021. Demographic data of newborns and pregnant women, surgical interventions, anesthetic procedures and perioperative care in the neonatal intensive care unit were collected from medical records. The main outcomes evaluated were time of orotracheal intubation and time on mechanical ventilation (TI/MV), time of use of PN, time to start enteral nutrition, time to full oral diet, length of stay in the neonatal intensive care unit, sepsis diagnosis, diagnosis of apnea,stridor, pneumonia and mortality rate. In the first ten days of the babies' lives, the doses of fentanyl used in the intraoperative and perioperative, in bolus or continuous infusion, were quantified. As well, a descriptive analysis of surgical approaches, anesthetic techniques and the clinical-surgical complications presented during the ICU stay was made. Through statistical modeling, the impact of increasing fentanyl doses on respiratory and gastrointestinal complications was evaluated. Results: During the study period, 184 children received surgical correction of the wall defect at IFF and the mortality rate was 8.69%. The data from 176 neonates were collected and 94% of these patients were identified as simple gastroschisis. Our cohort of 144 patients was evaluated and the most frequently related events to the use of fentanyl in higher doses were increased time on mechanical ventilation, increased total time of PN use, and delay in starting enteral feeding. Conclusion: The study demontrated worse respiratory and gastrointestinal outcomes in the neonates that received higher doses of fentanyl.

OBJECTIVE: To establish the prevalence of delirium and its subsyndrome in intensive care and to associate it with the use of sedative and analgesia, severity and mortality. METHOD: Carried out in two intensive care units of adult patients, this is a quantitative and transversal study, with 157 patients, using the Richmond Agitation-Sedation Scale to assess the level of sedation and the Intensive Care Delirium Screening Checklist for delirium. The T test and Chi-square test were applied for statistical analysis. RESULTS: The prevalence of delirium was 22.3%, and 49.7% of the subsyndrome. Associations of the use of midazolam with the presence of delirium (p=0.05) and subsyndromal delirium (p<0.01), use of clonidine with the appearance of delirium (p<0.01) and of fentanyl with subsyndromal delirium (p=0.09). There were no significant differences between the mortality of patients with delirium (p=0.40) and subsyndromal delirium (p=0.86), as well as association with the mortality score. CONCLUSION: The use of sedoanalgesia is associated with the presence of delirium and subsyndromal delirium. No significant statistical associations were found between the severity and mortality scores.

PURPOSE: To associate medications, anesthetic techniques, and clinical conditions that interfere in the time of patient approval in the safety protocol for thirst management. DESIGN: A quantitative, analytical, and longitudinal study conducted in Southern Brazil. METHODS: A nonprobabilistic sample, of 203 adult patients in the immediate postoperative period, evaluated every 15 minutes for 1 hour. FINDINGS: A general prevalence of thirst of 67.7%, and mean intensity of 6.38. Fentanyl, morphine, rocuronium, and sevoflurane increased lack of approval in the protocol within 30 minutes (P < .05). General anesthesia (P < .0001) and level of consciousness (95.4%) presented the highest nonapproval rates. CONCLUSIONS: Anesthetics and general anesthesia delayed protocol approval; however, after 30 minutes, 75.4% of patients had been approved. Level of consciousness was the main criterion of disapproval. The protocol identified crucial clinical conditions that made it impossible for the patient to receive thirst relief strategies and demonstrated that thirst can be satiated precociously with safety.

BACKGROUND AND OBJECTIVES: Fentanyl addition is a common practice when administering spinal anesthesia. Intrathecal fentanyl has been associated to increased postoperative pain and increase morphine consumption, but considered to be related to acute opioid tolerance. This prospective, randomized, blind study evaluates the effect of intrathecal fentanyl in the development of secondary hyperalgesia, measured with Von Frey filaments, in patients undergoing anterior cruciate ligament repair. METHODS: 46 patients having anterior cruciate ligament repair, received intrathecal hyperbaric bupivacaine 13.5 mg with fentanyl 20 mcg or no fentanyl addition. Light touch pain threshold was measured with von Frey filaments before anesthesia, at 6 and 24 hours post anesthesia in the non-operated thigh and in the forearm. Visual analogue pain scores and morphine consumption were also measured at the same time. RESULTS: Baseline thresholds to mechanical stimuli were similar in both groups. In the forearm, analysis showed a decreased threshold for the non-fentanyl group at 24 h p = 0.036. In the lower extremity, control and treatment group showed lower thresholds (secondary hyperalgesia) p = 0.002 but no difference between them p = 0.795. VAS score and morphine consumption did not differ among groups. CONCLUSIONS: Spinal fentanyl added to hyperbaric bupivacaine showed no evidence of an augmented state of hyperalgesia after ACL repair, neither by pain threshold modification nor clinical outcomes. On the contrary, at 24 h, fentanyl may have a protective effect at levels above the spinal block.
ANTECEDENTES Y OBJETIVOS: El uso de fentanilo es una práctica común en la administración de anestesia espinal. Su aplicación se ha asociado a un aumento del dolor post operatorio y a un aumento en el uso de morfina; por otro lado, se ha vinculado a una tolerancia aguda a opioides. El siguiente estudio prospectivo, randomizado y ciego, evalúa los efectos del fentanilo intratecal en la aparición de hiperalgesia secundaria, medida a través de filamentos Von Frey, en pacientes operados de ligamento cruzado anterior. METODOLOGÍA: Se incluyeron a 46 pacientes operados de ligamento cruzado anterior (LCA) con una dosis intratecal de bupivacaína hiperbárica de 13,5 mg; con y sin la adición de fentanilo de 20 mcg. Se midió el umbral del dolor mecánico, a través de filamentos Von Frey, antes de la anestesia, a las 6 y 24 horas postanestesia en el muslo no operado y en el antebrazo. Al mismo tiempo, se midió la puntuación del dolor en la escala verbal numérica (EVN) y el consumo de morfina. RESULTADOS: Los umbrales basales ante la estimulación mecánica resultaron similares en ambos grupos. En el antebrazo, el análisis mostró una disminución del umbral en el grupo de pacientes sin fentanilo, a las 24 h, p = 0,036 comparado con uso de fentanilo. En el muslo, el grupo control y tratamiento mostró umbrales más bajos (hiperalgesia secundaria) p = 0,002; no obstante, no se mostraron diferencias entre ellos. No se mostraron diferencias entre las puntuaciones de la EVN y el consumo de morfina en los dos grupos. CONCLUSIÓN: No hay evidencia que la adición de fentanilo espinal, a la dosis de bupivacaína hiperbárica, haya contribuido a un aumento en la hiperalgesia tras la reparación del LCA, medido por la modificación del umbral del dolor, ni en los resultados clínicos. Al contrario a las 24 h fentanilo puede tener un efecto protector de la hiperalgesia secundaria sobre el nivel del bloqueo espinal.
