ABSTRACT
ABSTRACT BACKGROUND AND OBJECTIVES: Wound complications and pharmacological pain relief methods used at the skin surgical site after cesarean delivery may result in women's physical and emotional burden. Thus, nonpharmacological treatments must be explored to avoid these complications and side effects on maternal health. The objective of this study was to investigate the effects of Combined Ultrasound and Electric Field Stimulation (CUSEFS) on cicatricial pain and functional capacity in immediate cesarean delivery. METHODS: This study has a randomized clinical trial, double-blind, and placebo-controlled design. Thirty women (25.7±5.0 years) in immediate postpartum were randomly assigned to three groups: Control (CG, n:9), CUSEFS (TG, n:11), and Placebo (PG, n:10). CUSEFS was performed once for 20 minutes. Cicatricial pain (McGill Pain Questionnaire) and functional capacity (Functional Capacity Check) was assessed at baseline, after the intervention, and after 30 minutes. Cohen's (d) and Mixed-design analysis of variance were used to compare groups. RESULTS: Immediately after the intervention, TG showed a decrease in cicatricial pain compared with CG in sensory (d:3.8 to 4.0), affective (d:4.0), and total categories (d:3.9). In functional capacity, TG had less difficulty than CG at walking (d:0.6) and lying down (d:1.1), and PG at rest (d: 0.9). CONCLUSION: CUSEFS might be a resource for managing cicatricial pain and functional capacity in immediate cesarean delivery. Further studies with longer duration and different CUSEFS doses/parameters are required.
RESUMO JUSTIFICATIVA E OBJETIVOS: As complicações na ferida e o uso de métodos farmacológicos de alívio da dor no local cirúrgico após a cesariana podem resultar em sobrecarga física e emocional para a mulher. Assim, tratamentos não farmacológicos devem ser explorados para evitar essas complicações e efeitos adversos à saúde materna. O objetivo deste estudo foi investigar os efeitos da terapia combinada de estimulação elétrica por meio do ultrassom (CUSEFS) na dor cicatricial e na capacidade funcional no pós-parto imediato de cesariana. MÉTODOS: Este estudo possui um desenho de ensaio clínico randomizado, duplo-cego e controlado por placebo. Trinta mulheres (25,7±5,0 anos) em pós-parto imediato de cesariana foram distribuídas aleatoriamente em três grupos: Controle (CG, n:9), CUSEFS (TG:11) e Placebo (PG, n:10). O CUSEFS foi realizado uma vez por 20 minutos. A dor cicatricial (Questionário de Dor McGill) e a capacidade funcional (Functional Capacity Check) foram avaliadas no início, após a intervenção e após 30 minutos. As análises de variância de design misto e Cohen (d) foram usadas para comparar os grupos. RESULTADOS: Imediatamente após a intervenção, o TG apresentou diminuição na dor cicatricial em relação ao CG nas categorias sensorial (d:3,8 a 4,0), afetiva (d:4,0) e total (d:3,9). Na capacidade funcional, o TG apresentou menor dificuldade que o CG na marcha (d:0,6) e deitado (d:1,1), e que o PG em repouso (d:0,9). CONCLUSÃO: O CUSEFS pode ser um recurso para o manejo da dor cicatricial e da capacidade funcional imediatamente após a cesariana. Além disso, são necessários mais estudos com maior duração e diferentes doses/parâmetros de CUSEFS.
ABSTRACT
Abstract Objectives: Cluster headache is considered a trigeminal autonomic cephalalgia and may present with characteristic symptoms of sympathetic/parasympathetic activation on the affected side of the face, such as nasal discharge, tearing, and conjunctival injection. Invasive therapies targeting the sphenopalatine ganglion have been performed in these headache syndromes and can have a medication-sparing effect, especially in refractory, difficult-to-manage cases. The gate control theory of pain suggests that electric pulses delivered to nerve tissues can modulate neuronal activity, thus aiding in management of nociceptive or neuropathic pain, and studies have demonstrated the efficacy and safety of sphenopalatine ganglion neurostimulation. Within this context, we sought to assess the feasibility of a new surgical technique for neurostimulation of the sphenopalatine ganglion in a cadaver dissection model. Methods: The technique was developed through dissection of two cadaver heads. We divided the procedure into two stages: an endonasal endoscopic approach to expose the sphenopalatine ganglion and confirm electrode placement, and a cervicofacial approach to introduce the electrode array and position the internal pulse-generator unit. Computed tomography was performed to confirm implant placement at the end of the procedure. Results: The pulse-generator unit was successfully placed through a retroauricular incision, as is already standard for cochlear implant placement. This should reduce the incidence of perioperative sequelae, especially pain and swelling in the oral region, which are a common complication of previous approaches used for this purpose. Control imaging confirmed proper electrode placement. The device used in this study allows the patient to modulate the intensity of the stimulus, reducing or even obviating the need for drug therapy. Conclusion: The novel technique described herein, based on percutaneous access guided by transmaxillary endoscopy, can provide great precision in electrode array positioning and decreased perioperative morbidity, combining the advantages of endoscopic approaches with those of the retroauricular route. Level of evidence: 3.
ABSTRACT
Abstract Introduction Upper airway stimulation (UAS) with electric activation of the hypo-glossal nerve has emerged as a promising treatment for patients with moderate-to-severe obstructive sleep apnea. Objective To retrospectively analyze objective and subjective outcome measures after long-term follow-up in obstructive sleep apnea patients receiving upper airway stimulation. Methods An observational retrospective single-center cohort study including a consecutive series of patients diagnosed with obstructive sleep apnea receiving upper airway stimulation. Results Twenty-five patients were included. The total median apnea-hypopnea index (AHI) significantly decreased from 37.4 to 8.7 events per hour at the 12-month follow-up (p < 0.001). The surgical success rate was 96%. Adverse events were reported by 28% of the patients. Conclusion Upper airway stimulation is an effective and safe treatment for obstructive sleep apnea in patients with continuous positive airway pressure (CPAP) failure or intolerance. However, it is possible that the existing in and exclusion criteria for UAS therapy in the Netherlands have positively influenced our results.
ABSTRACT
Abstract Introduction Aging reduces functional capacity related to reduced toe plantar flexion strength. The exercise for strengthening the foot's intrinsic muscles can be optimized using electrostimulation. Due to the scarcity of data in the literature on these methods, further studies are necessary. Objective To evaluate and compare the effects of training to strengthen the foot's intrinsic muscles on the risk of falls in older adults. Methods This is a randomized clinical trial with 19 older patients allocated into three groups: control (CG; n = 7), exercise (EG; n = 6), and exercise+electrostimulation (EEG; n = 6). The EG received an exercise protocol for the foot's intrinsic muscles, the EEG received the same protocol with Neuromuscular electrical stimulation (NMES), and the CG received guidance regarding preventing falls. The individuals were evaluated before and after the intervention using the Single-Limb balance test (SLBT), Functional Reach Test (FRT), Timed Up and Go (TUG), and Paper Grip Test (PGT) tests. One and two-way ANOVA was used for the statistical analysis. Statistical significance was set at p < 0.05. Results There was a significant improvement in the TUG test (9.64 ± 1.78 vs. 8.20 ± 1.94) in relation to the EG. With the EEG, there was an improvement both in the TUG (12.68 ± 4.01 vs. 10.61 ± 3.70) and in the FRT (26.37 ± 7.66 vs. 33.14±9.73) with p < 0.05). Conclusion An exercise protocol associated with electrostimulation improves performance in func-tional and dynamic balance tests in older adults.

O exercício de fortalecimento da musculatura intrínseca do pé pode ser otimizado com o uso da eletroestimulação eletro (EENM). Devido à escassez de dados na literatura sobre a utilização desses métodos, torna-se necessário realizar novos estudos. Objetivo Avaliar e comparar os efeitos do treino de fortalecimento da musculatura intrínseca do pé no risco de queda em idosos. Métodos Trata-se de um ensaio clínico randomizado, no qual 19 idosos foram alocados em três grupos: controle (GC; n = 7), exercício (GE; n = 6) e exercício+eletroestimulação (GEE; n = 6). O GE recebeu um protocolo de exercícios para a musculatura intrínseca do pé, o GEE recebeu o mesmo protocolo seguido de EENM e o GC recebeu orientações quanto à prevenção de quedas. Os indivíduos foram avaliados antes e após a intervenção através dos testes de Apoio Unipodal , Teste de Alcance Funcional (TAF), Timed Up and Go (TUG) e Paper Grip Test (PGT). Para a análise estatística, utilizou-se ANOVA 1 e 2 vias. Considerou-se estatisticamente significante um valor de p < 0,05. Resultados Observou-se melhora significativa no teste TUG (9,64 ± 1,78 vs 8,20 ± 1,94) em relação ao GE. Em relação ao GEE, houve melhora tanto no TUG (12,68 ± 4,01 vs 10,61 ± 3,70) quanto no TAF (26,37 ± 7,66 vs 33,14 ± 9,73). Conclusão Conclui-se que um protocolo de exercício associado à eletroestimulação melhora o desempenho nos testes de equilíbrio funcional e equilíbrio dinâmico em indivíduos idosos.
ABSTRACT
ObjectiveTo systematically evaluate the efficacy of electrical stimulation on shoulder-hand syndrome after stroke, and compare the curative effect of different electrical stimulation therapies. MethodsThe randomized controlled trials (RCT) about the effect of electrical stimulation on shoulder-hand syndrome after stroke were retrieved from eight databases, including PubMed, Web of Science, Embase, Cochrane Library, CNKI, CBM, VIP and Wanfang data, from the establishment to February 14th, 2023. Two researchers selected and screened the literature, and evaluated the quality of methodology independently. RevMan 5.4 software and Stata 14.0 software were used for meta-analysis and network meta-analysis, respectively. ResultsA total of 18 RCT were selected, including 1 310 cases. Compared to conventional rehabilitation therapy alone, electrical stimulation combined with conventional rehabilitation therapy could improve the scores of Fugl-Meyer Assessment-Upper Extremities (MD = 8.17, 95%CI 6.90 to 9.45, P < 0.001) and modified Barthel Index (MD = 11.80, 95%CI 10.18 to 13.42, P < 0.001), and reduce the Visual Analogue Score (MD = -1.68, 95%CI -2.03 to -1.32, P < 0.001) and edema score (MD = -0.98, 95%CI -1.18 to -0.79, P < 0.001). The best effect of improving upper limb function followed as intermediate frequency electrotherapy, electroacupuncture, low frequency electrotherapy and routine rehabilitation therapy. The best effect of improving pain followed as electroacupuncture, intermediate frequency electrotherapy, low frequency electrotherapy and routine rehabilitation therapy. ConclusionElectrical stimulation therapy can relieve pain and edema of patients with shoulder-hand syndrome after stroke, and improve upper limb activity and activities of daily living. Intermediate frequency electrotherapy is the best in improving upper limb function, and electroacupuncture is the best in relieving pain.
ABSTRACT
Objective:To evaluate the role of autophagy in electroacupuncture (EA)-induced improvement in sepsis-associated encephalopathy (SAE) in mice.Methods:A total of 135 healthy adult male mice, aged 8-12 weeks, weighing 22-25 g, were used in this study. Ten mice were randomly selected to prepare caecal slurry after anesthesia. The remaining 125 mice were divided into 5 groups ( n=25 each) using a random number table method: sham operation group (group Sham), SAE group, SAE+ EA group (group EA), SEA+ EA+ autophagy agonist rapamycin group (group SAE+ EA+ R), and SAE+ EA+ autophagy inhibitor 3-methyladenine group (group SAE+ EA+ MA). SAE was induced by intraperitoneal injection of cecal slurry 200 μl. Bilateral Zusanli (ST36) acupoints were stimulated at 2, 24, 48 and 72 h after surgery in group SAE+ EA, group SAE+ EA+ R and group SAE+ EA+ MA. Autophagy agonist rapamycin 10 mg/kg and autophagy inhibitor 3-methyladenine 15 mg/kg were intraperitoneally injected at 30 min before EA in SAE+ EA+ R group and SAE+ EA+ MA group, respectively. The survival of mice was recorded at 7 days after developing the model. Ten mice were selected from each group at 8-12 days after developing the model, and the learning and memory ability was assessed by Morris water maze test. Five mice from each group were sacrificed after anesthesia, brains were removed, and hippocampal tissues were obtained for determination of contents of interleukin-1beta (IL-1β), IL-18 and tumor necrosis factor-α (TNF-α) (by enzyme-linked immunosorbent assay) and expression of p62, autophagy-related protein 16 like protein 1 (ATG16L1), and nucleotide like receptor protein 3 (NLRP3) (by Western blot). Results:Compared with Sham group, the survival rate at 7 days after developing the model was significantly decreased in the other 4 groups ( P<0.01). There was no significant difference in the survival rate at 7 days after developing the model among SAE group, SAE+ EA group, SAE+ EA+ R group and SAE+ EA+ MA group ( P>0.05). Compared with Sham group, the activity time at the target quadrant was significantly shortened, the escape latency was prolonged, the number of crossing the original platform was reduced, the contents of TNF-α, IL-1β and IL-18 were increased, the expression of ATG16L1 was down-regulated, and the expression of p62 and NLRP3 was up-regulated in SAE group ( P<0.05). Compared with SAE group, the escape latency was significantly shortened, the activity time at the target quadrant was prolonged, the number of crossing the original platform was increased, the contents of TNF-α, IL-1β and IL-18 were decreased, the expression of ATG16L1 was up-regulated, and the expression of p62 and NLRP3 was down-regulated in SAE+ EA group ( P<0.05). Compared with SAE+ EA group, no significant change was found in the parameters of Morris water maze test ( P>0.05), the contents of TNF-α, IL-1β and IL-18 were significantly decreased, the expression of ATG16L1 was up-regulated, and the expression of NLRP3 and P62 was down-regulated in SAE+ EA+ R group, and the expression of ATG16L1 was significantly down-regulated, and the expression of p62 and NLRP3 was up-regulated in SAE+ EA+ MA group ( P<0.05). Conclusions:The mechanism by which EA improves SAE is related to promotion of autophagy in hippocampal neurons, inhibition of NLRP3 inflammasome activation, and alleviation of neuroinflammatory responses in mice.
ABSTRACT
Objective:To investigate the effect of electroacupuncture on calcium homeostasis in hippocampal neurons of mice with sepsis-associated encephalopathy (SAE).Methods:Twenty-four healthy male C57BL/6J mice, weighing 18-22 g, were divided into 4 groups ( n=6 each) using a random number table method: sham operation group (Sham group), SAE group, SAE plus electroacupuncture group (SAE+ EA group), and SAE plus sham electroacupuncture group (SAE+ SEA group). The virus carrying calcium ion (Ca 2+ ) fluorescent probes was injected and then an optical fiber was implanted into the hippocampal CA1 area to record the fluorescence signals of Ca 2+ . SAE was induced by cecal ligation and puncture in anesthetized mice at 3 weeks after administration. Starting from 3 days before surgery, Baihui and bilateral Quchi and bilateral Zusanli acupoints were stimulated for 30 min per day for 7 consecutive days in SAE+ EA group. In SAE+ SEA group, electroacupuncture was performed at the points 0.2 mm lateral to the corresponding acupoints without electrical stimulation. Open field tests were conducted at 5 days after surgery to record the number of rearing and changes in related Ca 2+ signals in hippocampal CA1 neurons. Novel object recognition tests were conducted at 6-7 days after surgery to record the recognition time and changes in related Ca 2+ signals in hippocampal CA1 neurons. Mice were sacrificed after the end of behavioral testing on 7 days after surgery, and brain tissues ipsilateral to the optical fiber implant were obtained and the fluorescence intensity of Ca 2+ in the hippocampal CA1 neurons was acquired using a fluorescent microscope. Results:Compared with Sham group, the number of rearing and amplitudes of related Ca 2+ signals in hippocampal CA1 neurons while rearing were significantly decreased in SAE group and SAE+ SEA group ( P<0.05), and no statistically significant changes were found in the parameters mentioned above in SAE+ EA group ( P>0.05), and the recognition index and amplitudes of related Ca 2+ signals while recognizing were significantly deceased, and the fluorescence intensity of Ca 2+ in hippocampal CA1 neurons was increased in SAE, SAE+ EA and SAE+ SEA groups ( P<0.05). Compared with SAE group and SAE+ SEA group, the number of rearing and amplitudes of related Ca 2+ signals in hippocampal CA1 neurons while rearing were significantly increased, the recognition index and amplitudes of related Ca 2+ signals in hippocampal CA1 neurons while recognizing were increased, and the fluorescence intensity of Ca 2+ in hippocampal CA1 neurons was decreased in SAE+ EA group ( P<0.05). There were no statistically significant differences in the parameters mentioned above between SAE group and SAE+ SEA group ( P>0.05). Conclusions:The mechanism by which electroacupuncture alleviates SAE may be related to regulation of Ca 2+ homeostasis in hippocampal neurons of mice.
ABSTRACT
Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.Methods:Sixty-eight pediatric patients of both sexes, aged 3-15 yr, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, undergoing elective lower extremity orthopedic surgery under general anesthesia, were divided into 2 groups ( n=34 each) by the random number table method: TEAS group (group T) and control group (group C). In group T, the bilateral Hegu and Neiguan acupoints were stimulated starting from 10 min before induction of anesthesia until the end of procedure, with the frequency of disperse-dense wave of 2/10 Hz, and the current intensity was gradually adjusted to the maximum intensity (10-15 mA) that children could tolerate. In group C, the electrodes were applied to the same acupoints, but electrical stimulation was not applied. The severity of pain was assessed by the Faces Pain Scale-Revised scale immediately after returning to the ward and at 2, 24 and 48 h after operation. The emergence agitation was evaluated using the Pediatric Anesthesia Emergence Delirium scale. The intraoperative consumption of propofol and remifentanil and time to extubation after stopping administration were recorded. The time to first pressing of patient-controlled analgesia (PCA), effective pressing times of PCA on 1st and 2nd days after surgery and postoperative adverse reactions such as postoperative nausea and vomiting, pruritus, drowsiness, and respiratory depression were recorded. Results:Compared with group C, the Faces Pain Scale-Revised scale scores were significantly decreased immediately after returning to the ward and at 2, 24 and 48 h after operation, the incidence of emergence agitation and intraoperative consumption of remifentanil were decreased, the time to extubation was shortened, the time to first pressing of PCA was prolonged, and the effective pressing times of PCA on 1st and 2nd days after surgery were decreased ( P<0.05). There was no significant difference in the intraoperative consumption of propofol and incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:TEAS can effectively enhance the effect of postoperative patient-controlled intravenous analgesia in pediatric patients undergoing lower extremity orthopedic surgery.
ABSTRACT
Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation with midnight-noon ebb-flow acupoint selection on postoperative delirium (POD) in the patients undergoing radical resection of colorectal cancer.Methods:A total of 93 patients of either sex, aged ≥18 yr, with body mass index <30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ, scheduled for elective radical resection of colorectal cancer under general anesthesia, were divided into 3 groups ( n=31 each) using a random number table method: control group (group C), common TEAS group (group CT), and midnight-noon ebb-flow acupoint selection TEAS group (group MT). The patients received TEAS at bilateral Hegu, Quchi and Shousanli acupoints at 6: 00 in group MT and at 18: 00 in group CT on the day of operation and 1-3 days after surgery, with a frequency of 2/100 Hz, disperse-dense waves, intensity the maximum current that could be tolerated, and each TEAS lasted for 30 min. In group C, only the electrodes were pasted at the same acupoints without electric current at 6: 00 am. The POD was evaluated by the Confusion Assessment Method (CAM) at 1, 3 and 5 days after operation (T 1-3). Blood samples were collected for determination of serum interleukin-1beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α) concentrations at 1 day before operation and at T 1. The time to first flatus and defection and adverse reactions after operation were recorded. Results:Compared with group C, the CAM scores at each time point and incidence of POD were significantly decreased, the concentrations of IL-1β, TNF-a and IL-6 in serum were decreased at T 1, the time to the first flatus and defecation was shortened, and the incidence of abdominal distension after surgery was decreased in MT and CT groups ( P<0.05). Compared with group CT, the CAM scores at T 3 and incidence of POD were significantly decreased, the concentrations of TNF-a and IL-6 at T 1 were decreased, and the time to first defecation after operation was shortened in group MT ( P<0.05). Conclusions:TEAS guided by midnight-noon ebb-flow acupoint selection provides better efficacy than common TEAS in decreasing the risk of POD in the patients undergoing radical resection of colorectal cancer, which is helpful for the early postoperative recovery of patients.
ABSTRACT
Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative acute lung injury (ALI) in the pediatric patients undergoing living-related liver transplantation.Methods:Sixty pediatric patients of either sex, aged 4-24 months, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with New York Heart Association (NYHA) class Ⅰ or Ⅱ, with Child-Pugh B or C, scheduled to undergo elective left external lobe piggyback living-related liver transplantation, were divided into 2 groups ( n=30 each) using a computer-generated table of random numbers: control group (group C) and TEAS group (group T). In group T, bilateral Zusanli (ST36), Neiguan (PC6), and Feishu (BL13) acupoints were stimulated with disperse-dense waves at the initial intensity of 0.5 mA and frequency of 2/15 Hz, the current intensity was gradually increased until local slight muscle shaking appeared, and continuous stimulation lasted for 30 min at a 30-min interval (a cycle) until the end of operation. TEAS was performed for 30 min at the same time every day up to 1 week after surgery. Stimulus locations in group C were selected at 0.5 cm lateral to the acupoints, and the electrodes with inert medium were attached to the location, with no effective current output from acupuncture treatment instrument. The peak inspiratory pressure, plateau pressure, and pulmonary compliance were recorded before skin incision (T 0), at 30 min after portal vein occlusion (T 1), at 1 h after portal vein opening (T 2), at the end of operation (T 3), and the difference between peak inspiratory pressure and plateau pressure was calculated. Blood samples from the jugular vein were collected at T 0-3 to determine the levels of plasma club cell protein 16 (CC16), surfactant protein D (SP-D), soluble receptor for advanced glycation end products (sRAGE), tumor necrosis factor-alpha (TNF-α), and interleukin-10 (IL-10) by enzyme-linked immunosorbent assay. Blood samples from the radial artery were collected at T 0-3 for blood gas analysis, PaO 2 and A-aDO 2 were recorded, and oxygenation index (OI) and respiratory index (RI) were calculated. The indwelling time of postoperative tracheal tube and length of ICU stay were also recorded. The lung injury was assessed and scored using ultrasound at 48 h after surgery. The occurrence of ALI within 1 week after operation was also recorded. Results:Compared with baseline at T 0, OI was significantly decreased, RI was increased, and plasma IL-10 concentrations were increased at T 2, 3, and the plasma concentrations of TNF-α, CC16, sRAGE and SP-D were increased at T 1-3 in both groups ( P<0.05). Compared with group C, OI was significantly increased, RI was decreased, the plasma concentrations of sRAGE were decreased, and the plasma concentrations of IL-10 were increased at T 2, 3, and the concentrations of plasma TNF-α, CC16 and SP-D were decreased at T 1-3, the indwelling time of postoperative tracheal tube and length of ICU stay were shortened, the ultrasound score of lung injury was decreased ( P<0.05), and no significant change was found in the incidence of ALI in group T ( P>0.05). Conclusions:TEAS can alleviate ALI in the pediatric patients after living-related liver transplantation.

RESUMO A dismenorreia primária é um distúrbio ginecológico caracterizado por dores cíclicas na lombar e abdômen inferior, com alta prevalência entre jovens, contribuindo para o absenteísmo. O presente trabalho teve como objetivo avaliar os efeitos da eletroterapia de baixa e média frequência em 30 participantes do sexo feminino, entre 18-26 anos, com queixa de dismenorreia primária. As participantes foram divididas em grupos que receberam: corrente TENS (frequência de 100 Hz e duração de pulso de 100 µs), corrente aussie (portadora de 4Khz modulada em 100 Hz com bursts de 4ms) e placebo (colocação dos eletrodos com o aparelho desligado). Todos os grupos eletroestimulados foram tratados com corrente no limiar sensorial e ajuste da intensidade a cada cinco minutos, sendo o tempo total de 30 minutos. Para a avaliação foi coletado a dor durante o ciclo menstrual (EVA), influência da dor nas atividades de vida diária e qualidade do sono (escalas visuais análogas do sono). Após análise estatística, conclui-se que houve redução significativa do quadro álgico em todos os grupos, sendo a corrente superior ao placebo. Em relação às AVD, todos os grupos apresentaram diferença significativa, e o grupo corrente aussie foi o único que obteve melhora nos três dias avaliados, mantendo o efeito analgésico tardio maior em comparação aos demais. A qualidade de sono pouco se alterou após os tratamentos propostos, necessitando de estudos futuros para fundamentar essa variável.
RESUMEN La dismenorrea primaria es un trastorno ginecológico caracterizado por dolores cíclicos en la zona lumbar y bajo abdomen, con alta prevalencia entre los jóvenes, lo que contribuye al absentismo. El presente estudio tuvo como objetivo determinar los efectos de la electroterapia de baja y media frecuencia en 30 participantes femeninas, de 18 a 26 años, con queja de la dismenorrea primaria. Las participantes se dividieron en grupos que recibieron: corriente TENS (frecuencia de 100 Hz y duración del pulso de 100μs), corriente aussie (4Khz modulada a 100 Hz con disparos de 4 ms) y placebo (colocación de electrodos con el dispositivo apagado). Todos los grupos fueron tratados con corriente en el umbral sensorial y ajuste de intensidad cada cinco minutos, con un tiempo total de 30 minutos. El dolor durante el ciclo menstrual (Escala Visual Analógica), la influencia del dolor en las actividades de la vida diaria y la calidad del sueño (escalas visuales análogas del sueño) fueron recogidos para la evaluación. Después del análisis estadístico, se puede concluir que hubo una reducción significativa del dolor en todos los grupos que recibieron intervención, siendo la corriente más alta que el placebo. En cuanto a la influencia del dolor en las actividades de la vida diaria, todos los grupos mostraron una diferencia significativa, pero el grupo aussie fue el único que mejoró en los tres días evaluados. La calidad del sueño cambió poco después de los tratamientos propuestos, requiriendo más estudios para apoyar esta variable.
ABSTRACT Primary dysmenorrhea is a gynecological disorder characterized by a cyclic pain in the lower back and abdomen, with a high prevalence among young women, which contributes to absenteeism. This study aimed to assess the effects of low and medium frequency electrotherapy in 30 women, aged from 18 to 26 years, who suffer from primary dysmenorrhea. Participants were divided into groups that received the transcutaneous electrical nerve stimulation current (frequency of 100Hz and 100μs pulses), Aussie current (4kHz carrier frequency, modulated at 100Hz, and 4ms bursts), and placebo (electrodes placed with the machine turned off). All treated groups received electrical current at the sensory threshold and its intensity was adjusted every five minutes. The treatment lasted 30 minutes. For the evaluation, pain during the menstrual cycle (via VAS), pain interference in activities of daily living (ADL), and sleep quality (via VAS sleep quality) were collected. After statistical analysis, pain reduced significantly in all groups evaluated, with better outcomes for the currents than for the placebo. Although all groups showed significant difference regarding ADL, the Aussie group was the only one that improved pain in all days evaluated. Sleep quality changed little after treatment, thus, further studies are required to assess this variable.
ABSTRACT
ABSTRACT BACKGROUND AND OBJECTIVES: Neuromuscular electrical stimulation (NMES) is one of the resources that can be used in the treatment of patients with chronic low back pain. It is possible that issues related to the stimulation parameters may affect the results obtained with the use of these currents. Therefore, the aim of this review was to investigate the effects of NMES on aspects of lumbopelvic muscle function in individuals with chronic low back pain. CONTENTS: The study is a systematic review that used 10 databases for the search through a comprehensive combination of descriptors that met the research question. The selection criteria based on the PICOT strategy were population - individuals with chronic low back pain (specific and/or non-specific); intervention - NMES; outcomes - paravertebral and/or abdominal muscle changes (muscle power and endurance). The articles were selected by two independent reviewers, who developed the tools for data extraction. Four articles were included in this review. In three of them, there was a significant increase in muscle strength and endurance, as well as muscle cross-sectional area in the group that received NMES compared to the control group. CONCLUSION: NMES showed positive effects in optimizing aspects of muscle function in individuals with chronic low back pain. However, the methods employed are very heterogeneous, which made it impossible to perform a quantitative analysis.
RESUMO JUSTIFICATIVA E OBJETIVOS: A estimulação elétrica neuromuscular (EENM) é um dos recursos que podem ser utilizados no tratamento de pacientes com dor lombar crônica. É possível que questões relacionadas aos parâmetros de estimulação possam afetar os resultados obtidos com o uso dessas correntes. Portanto, o objetivo deste estudo foi investigar os efeitos da EENM em aspectos da função muscular da região lombopélvica em indivíduos com dor lombar crônica. CONTEÚDO: Trata-se de uma revisão sistemática que utilizou 10 bases de dados para a busca por meio da combinação abrangente de descritores que atendessem a pergunta da investigação. Os critérios de seleção com base na estratégia PICOT foram: população - indivíduos com dor lombar crônica (específica e/ ou não específica); intervenção - EENM; desfechos - alterações musculares de paravertebrais e/ou abdominais (potência e resistência muscular). A seleção dos artigos foi feita por dois revisores independentes que elaboraram as ferramentas para extração dos dados. Ao todo, quatro artigos foram incluídos nesta revisão. Em três deles, houve aumento significativo de força e resistência muscular, assim como da área de secção transversa muscular no grupo que recebeu EENM, em relação ao controle. CONCLUSÃO: A EENM apresentou efeitos positivos na otimização dos aspectos da função muscular em indivíduos com dor lombar crônica. Porém, os métodos empregados são muito heterogêneos, o que impossibilitou a realização da análise quantitativa.
ABSTRACT
Avaliar os efeitos de diferentes frequências moduladas em amplitude (AMF-100Hz e AMF-10Hz) da corrente interferencial (CI) sobre o sistema nervoso autônomo (SNA) de voluntários saudáveis. Trinta voluntários saudáveis (23,7±2,7 anos) foram randomizados em intervenções placebo (desligado), CI com AMF-100Hz e CI com AMF-10Hz. As intervenções foram aplicadas na região ganglionar paravertebral por 30 minutos. O SNA foi avaliado pela variabilidade da frequência cardíaca antes e imediatamente após as intervenções. A intervenção em 10Hz reduziu a atividade simpática em 6% e aumentou a parassimpática em 6%. A intervenção de 100Hz aumentou 12% para a atividade simpática e diminuiu 12% para a atividade parassimpática. A CI altera o equilíbrio autonômico em voluntários saudáveis. 10Hz reduz a atividade simpática e aumenta parassimpático, embora o 100Hz tenha resultados opostos. A CI a 10Hz melhora o equilíbrio autonômico e apresenta efeitos potenciais a serem testados em pacientes hipertensos.
To evaluate the effects of different amplitude-modulated frequency (AMF-100Hz and AMF-10Hz) of the interferential current (IC) on autonomic nervous system (ANS) in healthy volunteers. Thirty healthy volunteers (23.7 ±2.7 years old) were randomized into placebo interventions (turned off), IC with AMF-100Hz and IC with AMF-10Hz. Interventions ware applied in the paravertebral ganglionar region for 30 minutes. ANS evaluated by the heart rate variability before and immediately after the interventions. 10Hz intervention reduced the sympathetic activity in 6% and an increase in the parasympathetic in 6%. 100Hz intervention increased 12% to sympathetic activity and decreased 12% to parasympathetic activity. IC changes the autonomic balance in healthy volunteers. 10Hz reduces the sympathetic activity and increases parasympathetic, although the 100Hz has opposite results. The IC at 10Hz improves the autonomic balance and presents potential effects to be tested in hypertensive patients.
ABSTRACT
Resumo Fundamento A estimulação ventricular direita convencional aumenta o risco de fibrilação atrial e insuficiência cardíaca em portadores de marca-passo.

Conclusão A estimulação cardíaca do sistema de condução His-Purkinje por meio da estimulação do ramo esquerdo é uma técnica segura e factível. Nesta casuística, apresentou alta taxa de sucesso, foi realizada com tempo de procedimento e fluoroscopia baixos e obteve medidas eletrônicas adequadas.
Abstract Background Conventional right ventricular pacing increases the risk of atrial fibrillation and heart failure in pacemaker patients. Stimulation of the left bundle branch (LBB) of the His-Purkinje system can prevent the unwanted outcomes of right ventricular pacing. Objective To retrospectively analyze the intraoperative outcomes, electrocardiographic and clinical data from the initial follow-up of patients submitted to stimulation of the LBB. Methods The electronic parameters of the implant and of possible early complications of 52 consecutive patients submitted to stimulation of the conduction system were evaluated. The adopted significance level was 0.05. Results Fifty-two patients underwent left bundle branch stimulation, with 50 successful procedures; 69.2% of the patients were male, and the median and interquartile range of age at the time of implantation was 73.5 (65.0-80.0) years. The pre-implant QRS duration was 146 (104-175) ms and 120 (112-130) ms after the procedure. The left ventricle activation time was 78 (70-84) ms. The R-wave amplitude was 12.00 (7.95-15.30) mV, with a stimulation threshold of 0.5 (0.4-0.7) V x 0.4 ms and impedance of 676 (534-780) ohms. The procedure duration was 116 (90-130) min, and the fluoroscopy time was 14.2 (10.0-21.6) min. Conclusion Cardiac stimulation of the His-Purkinje conduction system through the stimulation of the left bundle branch is a safe and feasible technique. In this study, it showed a high success rate, with low procedure and fluoroscopy periods, achieving adequate electronic measurements.

Resumo Fundamento A estimulação cardíaca artificial (ECA) por captura direta ou indireta do feixe de His resulta em contração ventricular sincrônica (ECA fisiológica). Objetivos Comparar sincronia cardíaca, características técnicas e resultados de parâmetros eletrônicos entre duas técnicas de ECA indireta do feixe de His: a não seletiva e a parahissiana. Métodos Intervenção experimental (novembro de 2019 a abril de 2020) com implante de marca-passo definitivo (MPd) DDD em pacientes com fração de ejeção ventricular esquerda > 35%. Foram comparadas a sincronia cardíaca resultante mediante algoritmo de análise eletrocardiográfica da variância espacial do QRS e as características técnicas associadas a cada método entre ECA hissiana não seletiva (DDD-His) e parahissiana (DDD-Var). Resultados De 51 pacientes (28 homens), 34 (66,7%) foram alocados no grupo DDD-Var e 17 (33,3%), no grupo DDD-His, com idade média de 74 e 79 anos, respectivamente. No grupo DDD-Var, a análise da variância espacial do QRS (índice de sincronia ventricular) mostrou melhora após o implante de MPd (p < 0,001). Ao ECG pós-implante, 91,2% dos pacientes do grupo DDD-Var mostraram padrão fisiológico de ECA, comprovando ativação similar à do DDD-His (88,2%; p = 0,999). O eixo do QRS estimulado também foi similar (fisiológico) para ambos os grupos. A mediana do tempo de fluoroscopia do implante foi de 7 minutos no grupo DDD-Var e de 21 minutos no DDD-His (p < 0,001), favorecendo a técnica parahissiana. A duração média do QRS aumentou nos pacientes do DDD-Var (114,7 ms pré-MPd e 128,2 ms pós-implante, p = 0,044). A detecção da onda R foi de 11,2 mV no grupo DDD-Var e de 6,0 mV no DDD-His (p = 0,001). Conclusão A ECA parahissiana comprova recrutamento indireto do feixe de His, mostrando-se uma estratégia eficaz e comparável à ECA fisiológica ao resultar em contração ventricular sincrônica similar à obtida por captura hissiana não seletiva.
Abstract Background Artificial cardiac pacing by direct or indirect His bundle capture results in synchronous ventricular contraction (physiological pacing). Objectives To compare cardiac synchronization, technical characteristics, and electronic parameters between two techniques of indirect His-bundle pacing: non-selective (NS-HBP) vs para-Hisian pacing (PHP). Methods The experimental intervention (between November 2019 and April 2020) consisted of implanting a DDD pacemaker in patients who had left ventricular ejection fraction (LVEF) > 35%. The resulting cardiac synchronization was compared using an electrocardiographic algorithm that analyzed QRS variation and the technical characteristics of non-selective Hisian pacing (DDD-His) and para-Hisian pacing (DDD-Var). Results Of 51 total patients (men: 28), 66.7% (34) were allocated to the DDD-Var group and 33.3% (17) to the DDD-His group. The mean ages in each group were 74 and 79 years, respectively. In the DDD-Var group, QRS variation (ventricular synchrony) improved after implantation (p < 0.001). In post-implantation ECG, 91.2% of the DDD-Var group presented a physiological pacing pattern, which was similar to the DDD-His group (88.2%; p = 0.999). The paced QRS axis was also similar (physiological) for both groups. Intraoperative fluoroscopy time (XRay) during implantation was lower for the para-Hisian technique (median 7 min in the DDD-Var group vs 21 min in the DDD-His group, p < 0.001). The mean QRS duration increased in the DDD-Var group (114.7 ms pre-implantation vs 128.2 ms post-implantation, p = 0.044). The mean post-implantation R-wave amplitude was 11.2 mV in the DDD-Var group vs 6.0 mV in the DDD-His group, p = 0.001. Conclusion Para-Hisian pacing appears to indirectly recruit the His bundle, which would make this an effective and comparable strategy for physiological pacing, resulting in synchronous ventricular contraction similar to that of non-selective Hisian pacing.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on emergence agitation in the patients undergoing thoracoscopic surgery.Methods:Eighty patients of both sexes, aged 25-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, undergoing elective thoracoscopic surgery under general anesthesia, were divided into 2 groups ( n=40 each) by a random number table method: TEAS group (group T) and control group (group C). In group T, the Hegu (L14), Zusanli (ST36) and Sanyinjiao (SP6) were stimulated starting from 30 min before induction of anesthesia until the end of operation, with a frequency of 2/100 Hz and disperse-dense waves.The intensity of stimulation was the maximum current that patients could tolerate.In group C, stimulating electrodes were placed at the same acupoints before induction, but no electrical stimulation was applied.Ramsay sedation score and VAS score were recorded.and emergence agitation was assessed using RSS agitation score.Blood samples from the median cubital vein or internal jugular vein were collected before anesthesia induction (T 1), at the end of surgery (T 2), immediately after removal of tracheal tube (T 3) and at 15 min after removal of tracheal tube (T 4) for determination of serum interleukin-6 (IL-6) and IL-10 concentrations by enzyme-linked immunosorbent assay.The intraoperative consumption of propofol, remifentanil and sufentanil was recorded.Adverse reactions such as tachycardia, bradycardia, hypertension, hypotension, respiratory depression, delay of awakening and nausea and vomiting were recorded after operation. Results:Compared with group C, the amount of intraoperative remifentanil consumed was significantly decreased, serum IL-6 concentrations were decreased, and the serum IL-10 concentration was increased T 2-4, Ramsay sedate score was increased, and the incidence of agitation was decreased in group T ( P<0.05). There was no significant difference in VAS score and incidence of postoperative adverse reactions between the two groups ( P>0.05). Conclusions:TEAS can reduce the development of emergence agitation in the patients undergoing thoracoscopic surgery, which is related to inhibition of inflammatory responses.
ABSTRACT
Objective:To evaluate the effect of electroacupuncture (EA) on gastric emptying in patients undergoing hepatobiliary surgery with preoperative fasting and drinking under the enhanced recover after surgery (ERAS) protocol.Methods:Seventy-six patients of both sexes, aged 18-75 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, who underwent elective laparoscopic hepatectomy or cholecystectomy from January 2019 to December 2020, were divided into 2 groups ( n=38 each) using a random number table method: control group (group C) and EA group.Both groups used the ERAS strategy of fasting and drinking before operation.Solid food was forbidden after 20: 00 the night before surgery, and 12.5% preoperative oral carbohydrate drinks 800 ml was taken orally from 20: 00 to 22: 00, and preoperative oral carbohydrate drinks 400 ml was taken orally from 5: 30 to 6: 00 on the morning of surgery.The bilateral Zusanli, Zhongwan, Neiguan, and Taichong were stimulated at 7: 30 in group EA, while sham acupoints were stimulated in group C. All the patients underwent ultrasonography of the gastric antrum at 8: 00 for measurement of the cross-sectional area (CSA) in the supine and right lateral decubitus positions (right-lat CSA), gastric volume (GV), ratio of gastric volume to weight (GV/W), and ratio of right-lat CSA to weight (CSA/W) were measured, and Perlas A semi-quantitative grating was performed.After induction of anesthesia, the level of mucous pepsin at the esophageal entrance was quantitatively determined by enzyme-linked immunosorbent assay, and positive expression was recorded.The adverse reactions such as nausea, vomiting and aspiration during induction of anesthesia were recorded. Results:Compared with group C, the supine CSA, right-lat CSA, GV, right-lat CSA/W, GV/W, Perlas A semi-quantitative grading, positive rate of pepsin and incidence of nausea were significantly decreased in group EA ( P<0.05). Conclusions:EA can promote gastric emptying in the patients undergoing hepatobiliary surgery with preoperative fasting and drinking under ERAS protocol.
