Effect of butorphanol-soaked nasal packing after endoscopic nasal surgery: a double-blind, randomized, placebo-controlled trial

Abstract Objective This study was designed to investigate the effect of butorphanol-soaked nasal packing on analgesia and sleep quality in patients undergoing bilateral endoscopic nasal surgery. Methods Sixty-six patients were enrolled and randomly allocated into three groups: group B1 (butorphanol 0.03 mg/kg), group B2 (butorphanol 0.04 mg/kg) and group N (control group). The primary outcome was postoperative pain scores evaluated by a Visual Analogue Scale (VAS) at 2 h (T1), 8 h (T2), 24 h (T3) and 48 h (T4) after surgery. Secondary outcome was postoperative sleep quality measured using Subjective Sleep Quality Value (SSQV). Results Postoperative VAS scores of butorphanol groups were significantly lower than the control group at T2, T3 and T4. VAS scores at each time point did not differ between groups B1 and B2. On the first and second nights after surgery, SSQV was higher in butorphanol groups than in the control group. There were no significant differences in SSQV1 and SSQV2 between group B1 and group B2. The incidence of respiratory depression, dizziness, agitation and rescue analgesic use did not show difference among three groups. Conclusions Butorphanol-soaked nasal packing can reduce pain and improve sleep quality after bilateral endoscopic nasal surgery without increasing adverse effects. A concentration of 0.03 mg/kg may be appropriate for clinical application. Level of Evidence Level 1B.

Morfina/ketamina versus morfina en el control del dolor postoperatorio de cirugía renal electiva / Morphine/ketamine versus morphine in postoperative pain control for elective renal surgery

Resumen: Introducción: el dolor agudo postoperatorio demora la recuperación funcional del paciente. Objetivo: evaluar utilidad de la ketamina asociada a morfina administrados en bolos intravenosos en el control del dolor agudo postoperatorio de pacientes sometidos a cirugía renal electiva. Material y métodos: realizamos estudio doble ciego en pacientes con dolor postoperatorio moderado-severo sometidos a cirugía renal electiva. Se conformaron dos grupos: grupo MK administramos morfina 0.05 mg/kg más ketamina 0.2 mg/kg y grupo M morfina 0.05 mg/kg más solución salina a 0.9%. Pacientes con dolor de intensidad moderada-severa según escala analógica visual recibieron dosis de morfina cada 20 minutos hasta lograr dolor ligero, registrándose el consumo total de morfina por paciente. La tensión arterial, frecuencia cardíaca y respiratoria, saturación de oxígeno y efectos adversos fueron evaluados con la misma periodicidad. Resultados: el grupo MK mostró menor intensidad del dolor con disminución significativa del consumo de morfina. Ambos grupos resultaron ser similares en cuanto a cifras de tensión arterial, frecuencia cardíaca, frecuencia respiratoria y saturación de oxígeno. Las náuseas y vómitos fueron los efectos adversos de mayor prevalencia, siendo superiores en el grupo morfina. Conclusiones: la asociación morfina-ketamina resultó útil en el control del dolor moderado-severo en pacientes sometidos a cirugía renal electiva.

Abstract: Introduction: acute postoperative pain delays the patient's functional recovery. Objective: to evaluate the utility of ketamine associated with morphine administered in intravenous boluses in the control of acute postoperative pain in patients undergoing elective renal surgery. Material and methods: we conducted a double-blind study in patients with moderate-severe postoperative pain undergoing elective renal surgery. Two groups were formed: group MK administered 0.05 mg/kg morphine plus 0.2 mg/kg ketamine and group M 0.05 mg/kg morphine plus 0.9% saline solution. Patients with pain of moderate-severe intensity according to the visual analogue scale received doses of morphine every 20 minutes until achieving light pain, recording the total consumption of morphine per patient. Blood pressure, heart and respiratory rates, oxygen saturation, and adverse effects were evaluated with the same periodicity. Results: MK group showed lower pain intensity with a significant decrease in morphine consumption. Both groups turned out to be similar in terms of blood pressure, heart rate, respiratory rate and oxygen saturation Figures. Nausea and vomiting were the most prevalent adverse effects, being higher in the morphine group. Conclusions: the morphine-ketamine association was useful in the control of moderate-severe pain in patients undergoing elective renal surgery.

Conclusiones: la infusión de lidocaína es efectiva para el manejo del dolor postquirúrgico inmediato, así como disminución de consumo de opioides y dosis de rescate analgésico, con una baja incidencia de náuseas y vómito, pero se asoció a hipotensión transoperatoria.

Abstract: Introduction: having an effective analgesia in the postoperative period is essential to avoid complications associated with pain in patients undergoing laparoscopic cholecystectomy. Objectives: test the effectiveness of intravenous lidocaine for postoperative pain in cholecystectomized patients by laparoscopy. Material and methods: an experimental, randomized, single-blind study was carried out in patients who underwent laparoscopic cholecystectomy at the No. 1 Regional General Hospital in Obregon, Sonora. They were divided into two groups randomly: group L to whom we applied lidocaine 1.5 mg/k in infusion and group P to whom placebo was applied. A statistical analysis was performed in SPSS v. 22 and a p < 0.05 was considered significant. Results: adequate pain management was observed in patients of group L upon admission to PACU (p = 0.002), lower consumption of transoperative fentanyl without statistical difference against placebo (p = 0.086), lower use of post-surgical rescue analgesia (p = 0.045), but higher incidence of adverse effects such as hypotension and bradycardia (p = 0.024). Conclusions: the infusion of lidocaine is effective for the management of immediate postsurgical pain; as well it decreases opioid consumption and analgesic rescue dose, with a low incidence of nausea and vomiting, but associated with hypotension after surgery.

Bloqueo del músculo erector de la espina como rescate analgésico para control de dolor agudo postoperatorio en fractura de escápula: reporte de caso / Erector spinae plane block as an analgesic rescue to acute control postoperative pain in scapula fracture: case report

Resumen: Introducción: el bloqueo en el plano del músculo erector de la espina (ESPB, por sus siglas en inglés) es un procedimiento seguro, en teoría menos exigente que las técnicas convencionales de anestesia regional torácica. Se utiliza para el tratamiento del dolor agudo y crónico. En la revisión de la literatura, no se encontraron informes de su uso como una técnica única en el dolor agudo de fractura de escápula. Presentación de caso: se reporta un caso clínico de ESPB como técnica experimental para el control del dolor postoperatorio agudo en fracturas de la escápula con aplicación a nivel T2. Se llevó a cabo postoperatorio con disminución de dolor después de 10 minutos de realizado, con una calificación de cero en la escala análoga del dolor. En este caso el ESPB fue realizado en el postoperatorio inmediato, con lo que se logró una disminución total del dolor a los 10 minutos, con posterior control de dolor a las 36 horas. Conclusión: este caso muestra la efectividad de ESPB como técnica experimental para control de dolor postoperatorio en fractura de escápula.

Abstract: Introduction: the erector spine plane block (ESPB) is a safe procedure, technically is less demanding than conventional thoracic regional anesthesia techniques. It is used for the treatment of acute and chronic pain. In the literature review, no reports of its use as a single technique in the acute pain of scapula fracture were found. Case presentation: ESPB is reported in a case as an experimental technique for controlling acute postoperative pain in scapula fractures with an application at the T2 level. It was performed postoperatively with a decrease in pain after 10 minutes and a score of zero on the analog pain scale. In this case, the ESPB was performed in the immediate postoperative period, achieving a total decrease in pain at 10 minutes, with subsequent pain control at 36 hours. Conclusion: this case shows the effectiveness of ESPB as an experimental technique for postoperative pain control in scapula fractures.

Postoperative analgesic efficacy of nefopam after anorectal surgery: a retrospective observational study

Objective: To examine the effectiveness of nefopam on postoperative pain control after anorectal surgeries. Methods: We retrospectively reviewed the electronic medical records of patients who underwent anorectal surgeries from January 2019 to March 2022 at two medical centers. The data were divided into nefopam and conventional groups. The primary outcome was the number of patients who requested additional opioids in the 24-h postoperative period. The secondary outcomes were numeric rating pain scores (NRPS) within a 24-h postoperative period and analgesic drugs-related side effects. Results: Eighty-seven patients in the conventional group and 60 in the nefopam group were recruited. The nefopam group reported less additional opioid consumption than the conventional group in all dimensions of analysis, including overall, adjusted to anesthetic techniques and types of surgery. However, these did not reach statistical significance (P = 0.093). Only patients in the nefopam group who underwent hemorrhoidectomy under TIVA or spinal anesthesia significantly required fewer additional opioids (P = 0.016, 60% mean difference). Similarly, the 24-h postoperative morphine consumption was lower in the nefopam group (mean difference = -3.4, 95%CI: 0.72,6.08). Furthermore, significantly lower NRPS were reported in the nefopam group during the 12-18 h postoperative period (P = 0.009). On the other hand, analgesic drugs related side effects were similar in both groups. Conclusions: The administration of nefopam after major anorectal surgery is beneficially evident in reducing postoperative opioid requirements. (AU)

Delirium and pain in patients in the immediate postoperative period of cardiac surgery: prevalence and associated risk factors / Delirium e dor em pacientes no pós-operatório imediato de cirurgia cardíaca: prevalência e fatores de risco associados

ABSTRACT BACKGROUND AND OBJECTIVES: Delirium is an acute mental status change, with fluctuating course and high incidence in cardiac surgery (CS) post-operative (PO) period. Delirium can lead to short and long-term consequences. The aim of this study was to assess the prevalence of delirium and pain and their risk factors on the 1st PO day after CS. METHODS: This was a cross-sectional analytical research. To determine the presence of PO delirium, the Confusion Assessment Method modified for Intensive Care Unit setting (CAM-ICU) and the Richmond Agitation Sedation Scale (RASS) were used. PO pain was analyzed using the Visual Analogue Pain Scale (VAS) and the presence of neuropathic components was analyzed using the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scale. After bedside analysis, patients were divided into Delirium (D) and Without Delirium (WD) groups. RESULTS: The total number of patients was 79. The prevalence of delirium was 16.5% (95% CI = 9.06 - 26.49%) and the mean number of comorbidities in the preoperative period was a significant risk factor for the occurrence of delirium (D =4.15±2.37 versus WD=2.96±1.78, p: 0.04). Another significant risk factor was the group older than 65 years of age, with the occurrence of delirium 1.45 times higher (PR=1.12-1.88, p: 0.0014). Regarding pain evaluation, 72.15% (95% CI 60.93 - 81.65%) reported it in the 1st PO day. CONCLUSION: The prevalence of delirium was similar to previous studies. The number of previous comorbidities and advanced age were risk factors for delirium. Pain was present predominantly over the sternotomy incision region.

RESUMO JUSTIFICATIVA E OBJETIVOS: Delirium é uma alteração aguda do estado mental, com curso flutuante e alta incidência no pós-operatório (PO) de cirurgia cardíaca (CC). O delirium pode levar a consequências a curto e longo prazo. O objetivo deste estudo foi avaliar a prevalência de delirium e dor e seus fatores de risco no 1º dia PO após CC. MÉTODOS: Trata-se de um estudo transversal analítico. Para determinar delirium no PO, foram utilizados o Confusion Assessment Method modificado para ambiente de Unidade de Terapia Intensiva (CAM-UTI) e a Richmond Agitation Sedation Scale (RASS). A dor PO foi analisada por meio da Escala Analógica Visual (EAV) e a presença de componentes neuropáticos foi analisada por meio da Escala de Avaliação de Sintomas e Sinais Neuropáticos de Leeds (LANSS). Após análise, os pacientes foram divididos nos grupos Delirium (D) e Sem Delirium (SD). RESULTADOS: Foram estudados 79 pacientes. A prevalência de delirium foi de 16,5% (IC 95%=9,06-26,49%) e o número médio de comorbidades no pré-operatório foi um fator de risco significativo para a ocorrência de delirium (D=4,15±2,37 versus SD=2,96±1,78, p: 0,04). Outro fator de risco foi o grupo com mais de 65 anos, com ocorrência de delirium 1,45 vezes maior (RP=1,12-1,88, p: 0,0014). Em relação à avaliação da dor, 72,15% (IC 95% 60,93-81,65%) a relataram no 1º dia PO. CONCLUSÃO: A prevalência de delirium foi semelhante à de estudos anteriores. O número de comorbidades prévias e a idade avançada foram fatores de risco para delirium. A dor estava presente predominantemente na região da incisão da esternotomia.

POSTOPERATIVE PAIN INCIDENCE AND INTENSITY FOLLOWING ROOT CANAL OBTURATION WITH BIOCERAMIC AND OTHER SEALERS: A SYSTEMATIC REVIEW WITH META-ANALYSIS

Aims: To investigate whether bioceramicsealers induce a lower incidence and intensity of postoperative pain compared to other sealers. Materials and Methods: Six electronic databases were searched for studies published up to April 2022, following the PICOS strategy: (P) adult patients undergoing root canal treatment or retreatment; (I) root canal filling using bioceramic sealer; (C) root canal filling using other types of sealers; (O) Primary: postoperative pain incidence and/or intensity; Secondary: number of medication intake; (S) randomizedclinical trials. Risk of bias assessment was performed with the revised Cochrane risk of bias tools for randomized trials (RoB 2). Overall certainty of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. Results: Ten studies were included. Eight studies had a low risk of bias, and two had some concerns risk. Meta-analyses showed no differences regarding postoperative pain intensity and incidence between bioceramic sealers and AH Plus. Number of medication intake seemed to be associated to the preoperative diagnosis. Zinc oxide-eugenol sealer demonstrated an intense postoperative pain compared to bioceramic sealers and AH Plus. GRADE analysis showed a low certainty of evidence for all outcomes. Conclusions: There seem to be no differences between bioceramic sealers and AH Plus regarding postoperative pain intensity and incidence. Number of medication intake seem to be associated to the preoperative diagnosis. Zinc oxide-eugenol evoked a more pronounced postoperative pain.

Actualización en analgesia preventiva y analgesia multimodal / Update on preventive analgesia and multimodal analgesia

Una deficiente calidad del manejo del dolor post operatorio agudo genera aumento en la morbilidad perioperatoria, disminuye la calidad de vida del paciente, aumenta los reingresos hospitalarios y, finalmente, los costes en salud. La analgesia preventiva y multimodal son dos estrategias que han sido implementadas para tratar de optimizar el manejo del dolor. Si bien en la primera, la evidencia es favorable a su empleo, aún no existe un total consenso en esto. A su vez, la analgesia multimodal, al emplear diferentes fármacos y/o técnicas, ha logrado evidenciar de mejor manera su utilidad y los beneficios al implementarla como terapia. En este artículo, revisamos la evidencia que certifica y avala el uso de éstas. Finalmente, a nuestro parecer, lo más importante en el quehacer del clínico, es lograr individualizar la estrategia que usaremos en el manejo del dolor postoperatorio, adaptándonos a las necesidades y el contexto propio de cada uno de nuestros pacientes.

A poor quality of acute postoperative pain management generates an increase in perioperative morbidity, decreases the quality of life of the patient, increases hospital readmissions and finally, increases health costs. Preventive and multimodal analgesia are two strategies that are implemented to try to optimize pain management. Although in the first, the evidence is favorable to its use, there is still no total consensus. At the same time, multimodal analgesia, by using different drugs and/or techniques, has demonstrated, in a better way, its usefulness and benefits when implemented as a therapy. In this article, we review the evidence that certifies and supports the use of these techniques. Finally, in our opinion, the most important thing in the clinician's task is to be able to individualize the strategy that we will use in postoperative pain management, adapting to the needs and context of each one of our patients.

Premedication with midazolam in low-risk surgery in children does not reduce postoperative delirium. Prospective cohort study

Introduction: Pediatric postoperative delirium is a frequent complication for which preventive pharmacological measures have been suggested. The use of midazolam as a prophylactic strategy has not yet been thoroughly assessed. Notwithstanding the fact that it is used in pediatric presurgical separation anxiety, its role in delirium is yet to be established. Objective: To quantify the incidence of pediatric postoperative delirium in patients undergoing low risk surgical interventions, exposed to oral midazolam-based premedication and to explore the protective and risk factors associated with the development of delirium. Methods: Prospective, analytical observational study with a cohort design. Children were conveniently selected in accordance with the daily list of surgical procedures in the operating rooms. The inclusion criteria were children between 2 and 10 years old, ASA I-II, undergoing low risk surgeries. Concurrent and longitudinal follow-up was then conducted upon admission to the post-anesthesia care unit (PACU) for the first hour. Results: A total of 518 children were included. The overall incidence of delirium was 14.4 % (95 % CI: 11.4 %-17.5 %). In the subgroup exposed to midazolam, 178 children were analyzed, with an incidence of delirium of 16.2% (95% CI of 10,8 %-21,7). These patients exhibited a higher tendency to delirium with the use of sevoflurane or fentanyl, and/orwhen presenting with severe postoperative pain. Patients exposed to propofol and/or remifentanil showed lower incidences. Conclusions: No reduction in the incidence of emergency pediatric delirium associated with the use of pre-surgical oral midazolam in low risk surgical procedures. Prospective controlled trials and additional research are required to study the effectiveness and safety of this intervention.

Introducción: El delirio pediátrico posoperatorio es una complicación frecuente para la cual se han sugerido medidas farmacológicas de prevención. El uso de midazolam como estrategia profiláctica aún no ha sido suficientemente evaluado. A pesar de que se emplea para la ansiedad de separación pediátrica prequirúrgica, su papel en delirio aún no se ha establecido. Objetivo: Cuantificar la incidencia de delirio pediátrico posoperatorio en pacientes sometidos a cirugías de bajo riesgo quirúrgico, expuestos a premedicación basada en midazolam oral y adicionalmente, explorar los factores protectores y de riesgo asociados a la ocurrencia. Materiales y métodos: Estudio observacional analítico prospectivo con un diseño de cohorte. Se seleccionaron niños por conveniencia de acuerdo con la lista quirúrgica diaria en salas de cirugía. Como criterios de inclusión se tomaron sujetos entre 2 y 10 años de edad, ASA 1-11, sometidos a cirugías de bajo riesgo quirúrgico. Posteriormente se realizó seguimiento concurrente y longitudinal al ingreso a la unidad de recuperación posanestésica (UCPA) durante la primera hora de estancia. Resultados: Se incluyeron 518 niños. La incidencia global de delirio fue del 14,4 % (IC 95 %;11,4 %-17,5 %). En el subgrupo expuesto a midazolam se analizaron 178 niños, quienes presentaron una incidencia de delirio del 16,2 % (IC 95 %;10,8 %-21,7 %). Estos pacientes presentaron una mayor tendencia a delirio con el uso de sevofluorano o fentanilo, y/o cuando presentaron dolor severo posoperatorio. Pacientes con exposición a propofol y/o remifentanilo exhibieron incidencias inferiores. Conclusiones: No se encontró una reducción en la incidencia de delirio pediátrico de emergencia asociada al empleo de midazolam oral prequirúrgico en cirugías de bajo riesgo. Se requieren estudios prospectivos controlados e investigación adicional para el estudio de la efectividad y seguridad de esta intervención.

Effect of preoperative anxiety level on postoperative pain, analgesic consumption in patients undergoing laparoscopic sleeve gastrectomy: an observational cohort study

Abstract Backgraund: This prospective observational cohort study aimed to investigate the relationship between preoperative anxiety levels and postoperative pain and analgesic requirement in patients undergoing laparoscopic sleeve gastrectomy. Methods: Forty two female patients with body mass index ≥ 35, who underwent laparoscopic sleeve gastrectomy for treatment of obesity were included in the study. Spielberger's state and trait anxiety scales were used in this study. Demographic data of the patients, anesthetic and analgesic drugs during the surgery, pain levels measured with verbal analog scale at the postoperative 1st, 4th, 12th, and 24th hour, sedation levels measured with the Ramsay sedation scale, and the amount of analgesic consumed were recorded. Anesthesiologist, surgeon, and patient were not informed of the anxiety level results. The relationship between preoperative anxiety and postoperative pain and analgesic consumption was evaluated by Spearman's correlation analysis. Stepwise multiple linear regression analysis was applied. Normal Distribution control was performed by applying the Shapiro-Wilk test to residual values obtained from the final model. Results: There was no relationship between trait anxiety level and postoperative pain and analgesic consumption. A correlation was found between state anxiety level and pain level up to 24 hours and analgesic consumption (p < 0.05). According to the obtained model it had been observed that the university graduates consumed more analgesic compared to other education level groups. Conclusion: In this study, a relationship was found between preoperative state anxiety level and 24-hour pain scores and analgesic consumption in patients who underwent laparoscopic sleeve gastrectomy under general anesthesia.

Effects of different hemostasis methods in laparoscopic ovarian cyst surgery on postoperative pain and sex hormone levels / 中华内分泌外科杂志

Objective:To study the effect of different hemostasis methods on postoperative pain and sex hormone levels in patients undergoing laparoscopic ovarian cystectomy.Methods:A total of 118 patients with ovarian cysts admitted to our hospital from Jun. 2018.6 to Aug. 2020 were collected and grouped by digital table method into electrocoagulation hemostasis group (59 cases, electrocoagulation hemostasis) and suture hemostasis group (59 cases, suture hemostasis). Pain at time points, serum inflammatory factors and sex hormone levels in the two groups were measured, and the incidence of complications was counted 12 weeks after surgery.Results:The VAS scores of suture hemostasis group at 6, 12 and 24 h after operation (3.33±0.93, 3.63±1.02, 3.01±0.94) were significantly lower than those of the electrocoagulation hemostasis group (4.16±1.05, 4.61±1.17, 3.72±1.05) ; there was no significant difference in serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) levels between the preoperative suture hemostasis group and the electrocoagulation hemostasis group. The serum levels of IL-6 and TNF-α in the group (37.64±4.82ng/L, 39.67±4.71ng/L) were lower than those in the electrocoagulation hemostasis group (45.96±5.25ng/L, 48.96±5.14ng/L) ( P<0.05) .) ; there was no significant difference in serum follicle-stimulating hormone (FSH), estradiol (E 2) or luteinizing hormone (LH) levels between preoperative electrocoagulation hemostasis group and suture hemostasis group ( P>0.05) ; There was no significant difference in the three indexes in the suture hemostasis group 3 months after operation compared with those before treatment ( P>0.05). The serum FSH and LH [ (6.59±0.91) mIU/ml, (5.24±0.77) mIU/ml] in the suture hemostasis group were lower than those in the electrocoagulation hemostasis group [ (7.39±1.02) mIU/m, (5.97±0.89) mIU/m], E 2 in suture hemostasis group [ (51.08±6.09) pg/ml] was higher than that in electrocoagulation hemostasis group [ (46.88±5.59) pg/ml] ( P<0.05). In terms of the complication rate at 3 months after operation, the suture hemostasis group (32.20%) was significantly lower than electrocoagulation hemostasis (13.56%) ( P<0.05). After 1 year of follow-up, the pregnancy success rate of the suture hemostasis group (72.88%) was significantly higher than that of the electrocoagulation hemostasis group (52.54%) ( P<0.05). There was no significant difference in pregnancy outcomes ( P>0.05) . Conclusions:Suture hemostasis in patients undergoing laparoscopic ovarian cystectomy is beneficial to relieve postoperative pain, improve postoperative inflammatory response, protect their ovarian function, avoid complications such as abnormal ovulation and excessive menstrual flow, and improve the success rate of pregnancy. The overall application effect is better than electrocoagulation hemostasis.

Introducción: La electroacupuntura induce la liberación de encefalina y b- endorfina. Objetivo: Evaluar la efectividad y seguridad de la electroacupuntura auricular para la analgesia posoperatoria en los pacientes electivos con diagnóstico quirúrgico de cáncer de piel. Métodos: Se realizó un estudio cuasi- experimental de intervención terapéutica en los pacientes electivos con diagnóstico de cáncer de piel, en el Hospital Provincial Docente de Oncología "María Curieˮ de Camagüey, en el período comprendido de enero de 2019 a enero de 2022. El universo fue de 200 pacientes, se constituyeron dos grupos, el grupo experimental integrado por 81 pacientes a los que se les aplicó electroacupuntura auricular preoperatoria y el grupo control formado por 119 pacientes a los que se les aplicó el tratamiento convencional. Resultados: Se observó predominio de la edad entre 55 a 59 años para ambos grupos de pacientes. Con la prueba estadística se planteó con un 95 % de confiabilidad que la intensidad del dolor posoperatorio cambio en relación al tratamiento empleado. La mayor parte de los pacientes tratados previamente con electroacupuntura auricular no presentó dolor en el posoperatorio (p = 0,000). El tratamiento impuesto guarda relación estadística significativa con la presencia de complicaciones posoperatorias relacionadas con el dolor, p ≤ 0,05. Se demostró la efectividad analgésica de la electroacupuntura (p = 0,000). Conclusiones: La electroacupuntura auricular para la analgesia posoperatoria en pacientes operados electivos de cáncer de piel, es eficaz y segura.

Introduction: Electroacupuncture induces enkephalin and b-endorphin release. Objective: To assess the effectiveness and safety of auricular electroacupuncture for postoperative analgesia in elective patients with a surgical diagnosis of skin cancer. Methods: A quasiexperimental study of therapeutic intervention was carried out in elective patients with skin cancer diagnosis, at María Curie Provincial Teaching Oncology Hospital of Camagüey, from January 2019 to January 2022. The study universe was two hundred patients. Two groups were made up: the experimental group, integrated by 81 patients, to whom preoperative auricular electroacupuncture was applied; and the control group, made up of 119 patients, to whom conventional treatment was applied. Results: Predominance of age between 55 and 59 years was observed for both groups of patients. The statistical test showed, with a reliability of 95 %, that the intensity of postoperative pain changed in relation to the used treatment. Most of the patients previously treated with auricular electroacupuncture did not present postoperative pain (p = 0.000). The employed treatment was statistically significant with respect to the presence of postoperative pain-related complications (p ≤ 0.05). The analgesic effectiveness of electroacupuncture was demonstrated (p = 0.000). Conclusions: Auricular electroacupuncture for postoperative analgesia in elective operated patients with skin cancer is effective and safe.

Comparison of Three Tonsillectomy Techniques: Cold Dissection, Monopolar Electrocautery, and Coblation

Abstract Introduction Tonsillectomy is among the most common otolaryngological surgeries. Objective To evaluate and compare three tonsillectomy techniques: cold steel dissection (CSD), monopolar electrocautery (MEC), and coblation. Methods The present study retrospectively reviewed the medical records of patients who underwent tonsillectomy between January 2014 and January 2016. Postoperative visual analog scale (VAS) pain scores, analgesic use, surgical duration, time to return to normal activity, and postoperative bleeding status were noted. Results The CSD group had less analgesic use and shorter return to normal activity than the MEC group (p =0.037 and p < 0.001, respectively). The coblation group had lower VAS pain scores than the MEC group only at 1 hour to 4 hours postsurgery (p <0.016). The postoperative bleeding rate was similar in all groups (p = 0.096). Conclusion Cold steel dissection tonsillectomy is associated with less postoperative pain and shorter recovery than MEC. Coblation is better than MEC in terms of postoperative pain at 1 hour to 4 hours only, whereas CSD is associated with less postoperative pain than coblation at 2 days to 7 days.

Analgesia after tonsillectomy with controlled intravenous morphine - overdue or exaggerated?

Abstract Objective: To assess the value of a morphine Patient Controlled Intravenous Analgesia (PCIA) after Tonsillectomies (TE). Methods: 30 adult patients were treated with oral analgesics (protocol group) and compared to 30 patients treated with a morphine PCIA for the first 3 Postoperative Days (PODs) after TE. Average and maximum pain severities (Numeric Rating Scale - NRS: 0-10) on PODs 1-3, analgesic score, quality of life, patient satisfaction and side effects were defined as outcome measures. Results: Average pain severities of the protocol and the PCIA group were of similar magnitude (NRS) (POD1: 4.48 vs. 4.71 [p = 0.68], POD2: 4.75 vs. 4.22 [p = 0.32] and POD3: 4.44 vs. 4.25 [p = 0.71]). Maximum pain intensities on POD1 (p = 0.92), POD2 (p = 0.51) and POD3 (p = 0.36) were also comparable between both groups. Patients with a PCIA consumed significantly more opioids (p = 0.001) without significant more side-effects. Conclusion: The PCIA did not provide a superior pain control compared to oral analgesics. In view of the considerable effort and the high opioid consumption, it cannot be recommended as a standardized application for pain control after TE.

Facteurs favorisant la douleur postopératoire aiguë après césarienne au Centre Hospitalier Universitaire Androva, Mahajanga, Madagascar / Risk factors for acute postoperative pain after caesarean section at the Androva University Hospital, Mahajanga, Madagascar

Une douleur aiguë postopératoire peut être source de complications à court voire à long terme si elle est sous-évaluée et sous traitée. Plusieurs facteurs interviennent à l'exacerbation de cette douleur. Notre objectif était de déterminer les facteurs cliniques influençant la sévérité de la douleur post opératoire immédiate après une césarienne. Méthodes : Une étude type cas-témoin portant sur les patientes césarisées était réalisée en salle de soins post-interventionnels du Centre Hospitalier Universitaire Professeur Zafisaona Gabriel Mahajanga allant de janvier 2019 au décembre 2019. L'étude statistique a été réalisée avec le logiciel Epi-Info® 3.5.4 de l'Organisation Mondiale de la Santé Genève et CDC Atlanta. Les mesures d'association ont été mesurées par le calcul d'Odds ratio. Le seuil de signification statistique (p) a été fixé à une valeur < 0,05. Résultats : Nous avons retenu 32 cas pour 64 témoins. La population d'étude était jeune et la majorité appartenait dans la tranche d'âge de 16 à 29 ans. Les facteurs qui interviennent sur l'intensité de la douleur postopératoire étaient surtout des facteurs liés à la patiente tels que le jeune âge (OR= 3,46 [1,17 - 10,18]; p=0,009), la gestité en l'occurrence la primigestité et la paucigestité (OR=2,77 [1,33 - 5,79]; p=0,002), la primiparité et la pauciparité (OR=5,67 [2,16 - 14,94]; p=< 0,001), l'anxiété préopératoire (OR=5,04 [1,99 - 12,74]; p=0,0003) et l'appartenance à la classe 2 selon la classification de l'American Society ofAnesthesiologists (OR=4,2 [1,49 - 11,76]; p=0,004). Conclusion : La connaissance de ces fac

Ketamine pour la gestion de la douleur post hystérectomie au CHU Professeur Zafisaona Gabriel Mahajanga Madagascar / Ketamine for the management of post-hysterectomy pain at the Professor Zafisaona Gabriel University Hospital, Mahajanga, Madagascar

Une analgésie multimodale est incontournable pour la prise en charge de la douleur post opératoire. L'objectif de notre étude était de montrer l'intérêt de l'utilisation de la kétamine, avec son effet analgésique, parmi les différentes molécules disponibles. Méthodes : Il s'agit d'une étude prospective monocentrique en simple aveugle de 31 cas d'hystérectomie programmée sur une période de 6 mois (mai­octobre 2016) divisée en deux groupes soumis au même protocole anesthésique : un groupe recevant de la kétamine en bolus suivi d'une perfusion continue peropératoire et sur les premières 24 heures et un groupe contrôle sans kétamine. En période post opératoire les deux groupes bénéficient d'une analgésie multimodale. L'analyse statistique a été faite par le test de Student. Résultats : Les scores de douleur diffèrent peu en moyenne sur les 24 heures de surveillance, tandis qu'une épargne morphinique importante est notée dans le groupe kétamine de l'ordre de 50% avec une valeur de p<0,001 fortement significative. A côté nous n'avons constaté aucun effet indésirable notable. Conclusion : L'adjonction de kétamine même de brève durée dans la prise en charge de la douleur post opératoire a permis de baisser considérablement la consommation morphinique

Analgesic effect of buccal acupuncture on patients after lumbar spinal fusion: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the effect of buccal acupuncture on pain after lumbar spinal fusion.@*METHODS@#Sixty patients undergoing lumbar spinal fusion were randomly divided into an observation group (30 cases, 1 case dropped off) and a control group (30 cases, 1 case was eliminated). The patients in the control group were treated with routine anesthesia. On the basis of the control group, the patients in the observation group were treated with buccal acupuncture at bilateral back point, waist point, and sacral point for 30 min per treatment. The first acupuncture was given before anesthesia induction, and then once a day postoperation for two days, totally 3 treatments. The dosage of sufentanil, the number of remedial analgesia, and the incidence of nausea and vomiting within 48 h after surgery were compared between the two groups; rest and motion visual analogue scale (VAS) scores at 2 (T1), 8 (T2), 12 (T3), 24 (T4), and 48 (T5) h after surgery were observed; the quality of recovery-15 scale (QoR-15) at 24 and 48 h after surgery were evaluated.@*RESULTS@#The dosage of sufentanil and the number of remedial analgesia within 48 h after surgery in the observation group were lower than those in the control group (P<0.01). There was no significant statistically difference in rest and motion VAS scores between the two groups in T1, T2, T3, T4 and T5 (P>0.05). The QoR-15 scores in the observation group at 24 and 48 h after surgery were higher than those in the control group (P<0.01). The incidence of nausea in the observation group was lower than that in the control group (P<0.05).@*CONCLUSION@#Buccal acupuncture could reduce the amount of postoperative analgesic drugs of patients after lumbar spinal fusion, and promote early postoperative recovery.

Application of wireless analgesic system in pain management after thoracoscopic lung resection: A retrospective cohort study with large sample / 中国胸心血管外科临床杂志

@#Objective     To investigate the effect of intravenous analgesia with a wireless or traditional analgesia pump system in thoracoscopic lung resection. Methods     Patients who used the patient-controlled intravenous analgesia after thoracoscopic lung resection between June 2016 and June 2021 were enrolled in the study. They were allocated into a wireless pump group (a ZigBee-based wireless analgesia pump system collecting data automatically) and a traditional analgesia pump group. Perioperative analgesia management followed the routine standard operation protocol of Shanghai Chest Hospital. The patients’ numeric rating scale (NRS) for pain and postoperative nausea and vomiting (PONV) scores were collected for analysis from the Anesthesia Information Record System. The incidence of postoperative analgesia insufficiency (defined as NRS≥4 points) within 48 h, the incidence of PONV within 24 h, and the 48 h completion rate of analgesia pump infusion were compared. Results    A total of 59 431 patients were collected, including 24 855 males and 34 576 females, 17 209 patients in the wireless pump group, and 42 222 patients in the traditional analgesia pump group. The incidence of analgesia insufficiency within 48 h after operation (3.75% vs. 4.98%, P=0.007), the incidence of PONV within 24 h after operation (13.60% vs. 16.70%, P=0.030) in the wireless pump group were lower than those in the traditional analgesia pump group. The 48 h completion rate of analgesia pump infusion in the wireless pump group was higher than that in the traditional analgesia pump group (83.40% vs. 71.90%, P<0.001). The wireless pump group could monitor the pressing times and use of the analgesia pump, while the traditional analgesia pump group could not record the relevant data. Conclusion    Compared with the traditional analgesia pump, the wireless analgesia management system may be convenient for timely, accurate and individualized management, and has good analgesic effect and low incidence of adverse reactions, and may be more suitable for perioperative analgesia management.

Acute and chronic pain after subxiphoid versus transcostal thoracoscopic extended thymectomy: A propensity score matching study / 中国胸心血管外科临床杂志

@#Objective     To compare and analyze the occurrence of acute and chronic pain after subxiphoid and transcostal thoracoscopic extended thymectomy. Methods    A retrospective analysis was performed on 150 patients who underwent thoracoscopic extended thymectomy in our hospital from July 2020 to June 2022, among whome 30 patients received subxiphoid video-assisted thoracic surgery, and 120 patients received transcostal video-assisted thoracic surgery. The patients were matched by the propensity score matching method. Postoperative pain was evaluated by numeric rating scale (NRS). The intraoperative conditions and postoperative pain incidence were compared between the two groups. Results    After matching, 60 patients were enrolled, 30 in each group, including 30 males and 30 females with an average age of 50.78±12.13 years. There was no difference in the general clinical data between the two groups (P>0.05), and no perioperative death. There were statistical differences in the intraoperative blood loss, postoperative drainage volume, postoperative catheter duration, postoperative hospital stay, postoperative pain on 1 d, 2 d, 3 d, 7 d, 3 months and 6 months after the surgery (P<0.05), but there was no statistical difference in the operation time or the postoperative 14 d NRS score (P>0.05). Further univariate and multivariate analyses for postoperative chronic pain showed that surgical method and postoperative 14 d NRS score were risk factors for chronic pain at the 3 months and 6 months after the surgery (P<0.05). Conclusion     The subxiphoid thoracoscopic extended thymectomy has advantages over transcostal thoracoscopic surgery in the postoperative acute and chronic pain.

The use of erector spinae versus transversus abdominis blocks in ovarian surgery: A randomized, comparative study / Uso del bloqueo del plano erector de la espina versus el plano transverso abdominal en cirugía de ovario: un estudio aleatorizado comparativo

Abstract Introduction: Inadequate pain control after major surgery can lead to significant complications. Ultrasound (US) guided plane blocks account for significant progress in regional anesthesia. Objective: This study explored the analgesic superiority of ultrasound-guided erector spinae (ESPB) and transversus abdominis (TAPB) plane blocks in patients undergoing major ovarian cancer surgery under general anesthesia. There have been no previous studies comparing their efficacy under these circumstances. Methods: This double-blind randomized comparative study included 60 patients undergoing major ovarian cancer surgery under general anesthesia. The ESPB group (n=30), received preoperative ultrasound-guided ESPB and the TAPB group (n=30), received preoperative low TAPB. Opioid consumption, HR, MAP, visual analogue scale (VAS) and adverse events were documented over 24 hours after surgery. Results: There was a highly significant difference in tramadol consumption between the two groups, with (95% CI: 16.23 to 50.43) and (95% CI: 59.23 to 95.43) for ESPB and TAPB groups, respectively. A significant difference (P < 0.01) was shown in intraoperative fentanyl consumption with (95% CI: 113 to 135.6) and (95% CI: 141.8 to 167.6) for ESPB and TAPB groups, respectively. A highly significant longer time to first analgesic request was recorded in the ESPB group (95% CI: 5.5 -15.3) (P < 0.001). VAS had a median of 2 (1-3) and 4 (2-6) for ESPB and TAPB groups, respectively, with F(1)=18.15, P=0.001 between groups. Postoperative HR and MAP in the TAPB group were significantly higher with more incidence of PONV. Conclusions: ESPB provided a more reliable analgesia versus TAPB in patients undergoing ovarian cancer surgery.

Resumen Introducción: El control inadecuado del dolor posterior a cirugía mayor puede generar complicaciones importantes. El bloqueo de los planos guiado por ecografía representa un avance significativo en anestesia regional. Objetivo: En el presente estudio se explora la superioridad analgésica de los bloqueos guiados por ecografía del plano erector de la espina (BPEE) y del plano transverso abdominal (BPTA) en pacientes sometidas a cirugía de cáncer de ovario bajo anestesia general. No se han hecho estudios previamente que comparen su eficacia bajo tales circunstancias. Métodos: Este estudio doble ciego, aleatorizado, comparativo, incluyó a 60 pacientes sometidas a cirugía mayor por cáncer de ovario, bajo anestesia general. El grupo del BPEE (n=30), recibió un BPEE guiado por ecografía, mientras que el grupo de BPTA (n=30), recibió un BPTA preoperatorio bajo. El consumo de opioides, la FC, la PAM, la escala visual analógica (EVA) y los eventos adversos, se documentaron durante las 24 horas posteriores a la cirugía. Resultados: Hubo una diferencia estadísticamente significativa en el consumo de tramadol entre los dos grupos, con un IC del 95% de 16,23 a 50,43 y un IC del 95% de 59,23 a 95,43 para los grupos de BPEE y de BPTA respectivamente. Se demostró una diferencia estadísticamente significativa (P < 0,01) en el consumo de fentanilo con un IC del 95%: 113 a 135,6 y un IC de 95%: 141,8 a 167,6 para los grupos de BPEE y BPTA, respectivamente. El tiempo transcurrido hasta la primera solicitud de analgésico en el grupo de BPEE fue significativamente más prolongado (IC 95%: 5,5 -15,3) (P < 0,001). La escala visual analógica - EVA - tuvo una mediana de 2 (1-3) y 4 (2-6) para los grupos del BPEE y BPTA, respectivamente, con F(1)=18,15, P=0,001 entre grupos. La FC y la PAM postoperatorias en el grupo de BPTA fueron significativamente superiores, con una mayor incidencia de nausea y vómito postoperatorios. Conclusiones: El BPEE proporcionó una analgesia más confiable que BPTA, en pacientes sometidas a cirugía de cáncer de ovario.
