RESUMO
STUDY OBJECTIVE: A Bayesian network meta-analysis was performed to compare the analgesic efficacy of the following nerve block techniques: femoral nerve block (FNB), adductor canal block (ACB), infiltration between the popliteal artery and the capsule of the posterior knee (iPACK), and genicular nerve block (GNB) following total knee arthroplasty (TKA). DESIGN: Systematic review and network meta-analysis (NMA). PATIENTS AND MEASUREMENTS: We searched the Web of Science, PubMed, EMBASE, and Cochrane Library databases until September 20, 2022. Patients who were treated by any of the above four nerve block techniques (alone or in combination) after TKA were included. Patients who underwent minimally invasive knee surgery were excluded. The indicators included pain scores during rest and mobilization, opioid consumption after surgery, postsurgical mobilization function (ROM [range of motion], TUG [Timed-Up-and-Go] test) at 24 h and 48 h, and length of hospital stay. The risk of bias was assessed by the Cochrane risk of bias tool. RESULTS: Forty-two studies involving 2857 patients were eligible for this study. This NMA suggested that ACB + iPACK was the most efficacious option for improving ambulation ability and shortening the length of hospital stay. Furthermore, ACB + iPACK was the best regimen for resting-pain and movement-pain relief (78% and 87%, respectively) and for reducing opioid consumption (90%) at 48 h. However, FNB + iPACK was the most efficacious option for relief of resting pain (42%) and reducing opioid consumption (68%) at 24 h; GNB was the most efficacious option for movement pain relief at 24 h (94%). CONCLUSION: Considering both pain control and knee functional recovery, ACB + iPACK may be the optimal analgesic regimen for patients after TKA. At the same time, it significantly reduces pain and opioid consumption at 48 h. However, ACB + iPACK is not the recommended technique for short-term (24 h) pain control. CLINICAL TRIAL REGISTRATION: PROSPERO (CRD42022362322).

PURPOSE: To compare the difference in analgesic effect between femoral triangle block (FTB) and adductor canal block (ACB) during arthroscopic knee surgery. METHODS: Patients who underwent arthroscopic knee surgery were randomized preoperatively to FTB group or ACB group. For each group, 20 mL of 0.1% ropivacaine was injected. PRIMARY OUTCOMES: The numeric rating score (NRS) at 12 h after surgery at rest and during movement. SECONDARY OUTCOME: (1) The NRS at post anesthesia care unit (PACU) and 2, 24 h after surgery at rest and during movement; (2) The quadriceps muscle strength at PACU and 2, 12, 24 h after surgery; (3) Consumption of Rescue analgesia; (4) Incidence of adverse reactions. RESULTS: The NRS at 12 h after surgery at rest and during movement of ACB group were higher than FTB group. Among secondary outcomes, the NRS at PACU at rest and during movement, 2 h after surgery during movement of FTB group lower than ACB group; the quadriceps muscle strength at 2 h after surgery of FTB group stronger than ACB group. After multiple linear regression model analysis, the data showed additional statistically significant reduction NRS at 24 h after surgery at rest (0.757, p = 0.037) in FTB group. Other outcomes were similar between two groups. CONCLUSIONS: The FTB appears to provide superior pain control after knee arthroscopy than ACB, the FTB is superior to the ACB in quadriceps muscle strength at 2 h after surgery. TRIAL REGISTRATION: The trial was registered in the Chinese Clinical Trial Registry (ChiCTR2300068765). Registration date: 28/02/2023.

OBJECTIVES: A single nerve block provides excellent analgesia in a short time, but rebound pain after the nerve block dissipates has attracted researchers' attention. The aim of this study was to evaluate the effect of perineural dexamethasone on rebound pain after sciatic nerve block and femoral nerve block in patients undergoing unicompartmental knee arthroplasty (UKA). METHODS: In a double-blinded fashion, we recruited 72 patients undergoing UKA, each of whom received sciatic and femoral nerve block. Patients were randomly assigned to 2 groups (n=36): X (ropivacaine only) and D (ropivacaine combined with dexamethasone). The primary outcome was the incidence of rebound pain. The secondary outcomes were rebound pain score, the duration of rebound pain, the duration of nerve block, pain score, sufentanil consumption and rescue analgesic, patient-controlled intravenous analgesia, distance walked, sleep quality score, C-reactive protein levels, and adverse effects. RESULTS: Compared with group X, the incidence of rebound pain in group D was higher, the rebound pain score was higher and the duration of the nerve block was prolonged ( P <0.05). At 12, 16, and 20 hours postoperatively, the pain scores at rest in group D were lower. At 32 and 36 hours postoperatively, the pain scores at rest in group D were higher ( P <0.05). Furthermore, patients in group D had lower levels of C-reactive protein after surgery ( P <0.05). DISCUSSION: The addition of dexmedetomidine to ropivacaine for UKA effectively prolonged the duration of nerve block and decreased C-reactive protein levels, but increased the incidence of rebound pain and rebound pain score, and had no beneficial effects on the postoperative analgesia.

OBJECTIVES: This study aimed to compare the analgesic effects of continuous femoral nerve block (FNB), femoral triangle block (FTB), and adductor canal block (ACB) following total knee arthroplasty (TKA). The goal was to identify the most effective nerve block technique among these. METHODS: Patients undergoing TKA were randomly assigned to 1 of 3 groups: FNB, FTB, or ACB. Nerve blocks were administered preoperatively, with catheters placed for patient-controlled nerve analgesia (PCNA). The primary end point was the Numeric Rating Scale (NRS) score at movement at 24 hours postsurgery. Secondary end points included NRS scores at rest and movement, quadriceps strength, Timed Up and Go (TUG) test performance, range of motion, effective PCNA utilization, and opioid consumption at various postsurgery time points. RESULTS: Of the 94 valid data sets analyzed (FNB: 31, FTB: 31, ACB: 32), significant differences were observed in the primary end point (H=7.003, P =0.03). Post hoc analysis with Bonferroni correction showed that the FNB group had a significantly lower median pain score (3 [2 to 4]) compared with the ACB group (4 [3 to 5], Bonferroni-adjusted P =0.03). Regarding secondary end points, both the FNB and FTB groups had significantly lower NRS scores than the ACB group at various time points after surgery. Quadriceps strength and TUG completion were better in the FTB and ACB groups. There were no statistically significant differences among the groups for the other end points. DISCUSSION: Continuous FTB provides postoperative analgesia comparable to FNB but with the advantage of significantly less impact on quadriceps muscle strength, a benefit not seen with FNB. Both FTB and ACB are effective in preserving quadriceps strength postoperatively.

OBJECTIVES: Despite the use of multimodal analgesia, patients undergoing knee arthroplasty still encounter residual moderate pain. The addition of betamethasone to local anesthetic has been shown to improve postoperative pain. However, it remains uncertain whether the positive effects of perineural or intravenous administration of betamethasone on analgesia outcomes lead to better early mobility and postoperative recovery. METHODS: Between June 2022 and February 2023, a total of 159 patients who were undergoing knee arthroplasty were included in this study. These patients were allocated randomly into three groups: (i) the NS group, received ropivacaine 0.375% and intravenous 3mL 0.9% normal saline; (ii) the PNB group, received ropivacaine 0.375% plus perineural betamethasone (12mg) 3mL and intravenous 3mL 0.9% normal saline; and (iii) the IVB group, received ropivacaine 0.375% and intravenous betamethasone (12mg) 3mL. RESULTS: Both perineural and intravenous administration of betamethasone led to improved median (IQR) numeric rating scale (NRS) scores on the 6-meter walk test, with a score of 1.0 (1.0-2.0) for both groups, compared with 2.0 (1.0-2.0) for the NS group (p = 0.003). Compared to the NS group, both the PNB and IVB groups showed significant reductions in NRS scores at 24 and 36 h after surgery, along with a significant increase in ROM at 24, 36, and 48 h post-operation. Additionally, it exhibited lower levels of cytokine IL-1ß and TNF-α in fluid samples, as well as lower level of HS-CRP in blood samples in the PNB and IVB groups compared to the NS group. CONCLUSION: The administration of perineural and intravenous betamethasone demonstrated an enhanced analgesic effect following knee arthroplasty. Furthermore, it was associated with reduced levels of IL-1ß, TNF-α, and HS-CRP, as well as enhanced knee ROM, which is conducive to early ambulation and postoperative rehabilitation after knee arthroplasty.

Ultrasound regional blockade emerged that blocks the branches of the femoral nerve, obturator and accessory obturator that innervate the anterior hip capsule, the PENG block (group of pericapsular nerves), which by its Recent description does not have enough evidence in medical practice. To verify the analgesic effect of the PENG block in patients with hip fracture and its analgesic permanence during the first 10 hours after the block in patients admitted with a diagnosis of hip fracture, at the General Interzonal Hospital of Acute "Dr Oscar E Alende "From Mar del Plata, Argentina, in the months of May to November 2019. A prospective descriptive observational study was carried out with a total of 53 patients, hospitalized patients with a diagnosis of hip fracture, with standardized intravenous analgesic scheme and who have not yet undergone hip surgery. Pain was evaluated with the EVA scale (visual analog scale) prior to the blockage, and then at 30 min and 10 hours after the blockade, 15 ml of 1% lidocaine and 15 ml of bupivacaine at 0 were used. 25%, convex or linear ultrasound probe according to patient weight and 100 mm needle. In order to reproduce and evaluate the pain, the patients had a 30º flexion of the hip. Prior to the blockade, 66% of the patients had severe pain and 34% moderate pain, none presented mild pain or absence, both at thirty minutes and ten hours after the blockade, no patient presented severe pain and all patients presented analgesia with a decrease in more than three points on the VAS scale, in some cases reaching a decrease of 10 points on that scale. The PENG block is a regional anesthesia technique that provides very good analgesia to patients with hip fractures, therefore, it is an excellent saving strategy for systemic analgesics. Knowing the analgesia provided by the blockade at 30 min and at 10 h, it could be performed both in the preoperative period for the transfer and mobilization of the patient, as well as in the postoperative period, which could save the use of opioids and decrease hospital stay.
INTRODUCCIÓN La fractura de cadera es una emergencia ortopédica común en ancianos asociada a gran morbimortalidad, una adecuada analgesia regional perioperatoria determina un ahorro en el uso de analgésicos sistémicos. Recientemente, en el año 2018, surgió un nuevo bloqueo regional ecoguiado muy prometedor que bloquea las ramas del nervio femoral, obturador y obturador accesorio que inervan la capsula anterior de la cadera, el bloqueo PENG (grupo de nervios pericapsulares), el cual por su reciente descripción no cuenta con la suficiente evidencia en la práctica médica. OBJETIVOS: Comprobar el efecto analgésico del bloqueo PENG en pacientes con fractura de cadera y su permanencia analgésica durante las 10 primeras horas posteriores al bloqueo en los pacientes internados con diagnóstico de fractura de cadera, en el Hospital Interzonal General de Agudos "Dr. Oscar E Alende" de Mar del Plata, Argentina, en los meses de mayo a noviembre del 2019. MATERIALES Y MÉTODOS: Se realizó un estudio observacional descriptivo prospectivo con un total de 53 pacientes, se incluyeron pacientes internados con diagnóstico de fractura de cadera, con esquema analgésico endovenoso estandarizado y que aún no hayan sido sometido a cirugía de cadera. Se evaluó el dolor con la escala EVA (escala análoga visual) previo al bloqueo, y luego a los 30 min y a las 10 Hs de haber realizado el bloqueo, para este se utilizaron 15 ml lidocaína 1% y 15 ml de bupivacaína al 0,25%, sonda ecográfica convexa o lineal según el peso del paciente y aguja 100 mm. Para reproducir y evaluar el dolor se les realizo a los pacientes una flexión de 30º de la cadera. RESULTADOS: Previo al bloqueo el 66% de los pacientes tuvieron dolor severo y 34% dolor moderado, ninguno presentaba dolor leve o ausencia del mismo, tanto a los treinta minutos como a las diez horas posteriores al bloqueo ningún paciente presento dolor severo y todos los pacientes presentaron analgesia con una disminución en más de tres puntos en la escala de EVA, llegando en algunos casos a una disminución de 10 puntos de dicha escala. CONCLUSIONES: El bloqueo PENG es una técnica de anestesia regional que brinda muy buena analgesia a los pacientes con fractura de cadera, por consiguiente, es una excelente estrategia ahorradora de analgésicos sistémicos. Conociendo la analgesia que brinda el bloqueo a los 30 min y a las 10 h de realizado, se podría realizar dicho bloqueo tanto en el preoperatorio para el traslado y movilización del paciente, como en el post-operatorio, lo que podría ahorrar el uso de opioides y disminuir la estancia hospitalaria.

Since the start of the COVID-19 pandemic, several anesthetic societies have generated clinical recommendations for the perioperative management of these patients, including the Chilean Society of Anesthesiology. Among these recommendations, the advantages of regional anesthesia have been highlighted. In this article, we report and discuss the case of a 59-year-old patient with diabetes mellitus II, Chronic Arterial Hypertension, Gout, and Stage IV Chronic Renal Failure admitted with a multifocal septic condition characterized by suppurative collections including a large subcutaneous lumbar abscess recently drained. The patient evolved with left knee septic arthritis and was scheduled for arthroscopic irrigation and debridement. As per protocol a SARS-COV2 PCR was tested and resulted positive. It was decided to proceed to surgery under anesthetic ultrasound-guided femoral and sciatic nerve blocks using an adrenalized (2.5 ug/mL) solution of 0.33% Levobupivacaine- 0.66% Lidocaine (15 mL each). Fifteen minutes later, the knee was mobilized passively without pain. Surgery started after 30 minutes. The surgical and anesthetic conditions were described as adequate by the surgeon and the patient, respectively. The postoperative evolution was satisfactory without presenting respiratory symptoms and the patient was discharged 17 days after under oral antibiotic treatment.
Desde el comienzo de la pandemia de COviD-19, varias sociedades de anestesia han generado recomendaciones clínicas para el tratamiento perioperatorio de estos pacientes, incluida la Sociedad Chilena de Anestesiología. Entre estas recomendaciones, se han destacado las ventajas de la anestesia regional. En este artículo, reportamos y discutimos el caso de un paciente de 59 años con diabetes mellitus tipo 2, hipertensión arterial, gota e insuficiencia renal crónica en etapa IV, admitido por una sepsis multifocal caracterizada por colecciones supurativas que incluyen un gran absceso lumbar subcutáneo drenado recientemente. El paciente evolucionó con artritis séptica de rodilla requiriendo de una exploración y aseo artroscópico. Por protocolo perioperatorio COviD-19, se solicitó PCR para SARS-COv2 con un resultado positivo. Se decidió proceder a la cirugía bajo bloqueos anestésicos guiados por ultrasonido de nervios femoral y ciático utilizando una solución adrenalizada (2,5 ug/mL) de levobupivacaína al 0,33% lidocaína al 0,66% (15 mL en cada uno). Quince minutos después, la rodilla se movilizó pasivamente sin dolor. La cirugía se inició tras media hora empleando una ligera sedación con propofol. Las condiciones quirúrgicas y anestésicas fueron descritas como adecuadas por el cirujano y el paciente. Este último evolucionó favorablemente, sin síntomas respiratorios y fue dado de alta 17 días después con tratamiento antibiótico oral.

Justificativa e Objetivos: Winnie e col descreveram a técnica do bloqueio do nervo lateral cutâneo da coxa, femoral e obturador através de injeçäo única de anestésico local no conduto fascial muscular englobando o nervo femoral. O objetivo deste estudo foi avaliar a eficácia da injeçäo única de bupivacaína 0,25 por cento através do bloqueio "3 em 1" identificado pelo estimulador de nervos periféricos ou pela perda da resistência à punçäo, na analgesia pós-operatória de 100 pacientes de cirurgia ortopédicas submetidos à raquianestesia. Método: Cem pacientes escalados para cirurgia ortopédicas sob raquianestesia receberam o bloqueio "3 em 1" de acordo com a técnica de Winnie, identificando o nervo femoral com estimulador de nervos periféricos ou através do teste da perda da resistência, para analgesia pós-operatória de 100 pacientes de cirurgia ortopédicas sob raquianestesia receberam o bloqueio "3 em 1" de acordo com a técnica de Winnie, identificando o nervo femoral com estimulador de nervos periféricos ou através do teste da perda da resistência, para analgesia pós-operatória, sendo injetados 40 ml de bupivacaína 0,25 por cento sem epinefrina. Foi avaliado o bloqueio nos nervos lateral cutâneo, femoral e obturador às 4, 8, 12, 16, 20 e 24 horas. A quantidade de opióides administrada em cada paciente foi anotada nas primeiras 24 horas. Em alguns pacientes foi avaliada a dispersäo do anestésico através de estudo radiográfico com contraste iodado näo iônico. Resultados: O bloqueio "3 em 1" foi obtido em 93 por cento dos pacientes. Näo ocorreu diferença significativa na incidência dos bloqueios nos três nervos durante as primeiras 24 horas. O tempo médio de analgesia foi significativamente maior com o cateter (17,64 horas) quando comparado com o estimulador de nervos (14,06 horas). O bloqueio reduziu a quantidade de opióides administrados após a cirurgia, sendo que 43 por cento dos pacientes näo necessitaram de complementaçäo analgésica no pós-operatório. Näo ocorreu diferença na necessidade de doses complementares de analgésicos nos dois grupos nas primeiras 24 horas. Näo foram observados sinais e sintomas clínicos de toxicidade da bupivacaína nem seqüelas associadas ao bloqueio dos nervos. A dispersäo do anestésico no estudo radiográfico foi praticamente a mesma com ambas as formas de bloqueio
