La aplicación de crioterapia en endodoncia consta de la irrigación con solución salina a temperaturas bajas con la finalidad de reducir el dolor post-operatorio en un tratamiento de conducto radicular. El objetivo de este estudio fue comparar la reducción térmica de la superficie radicular externa a través de la crioterapia intracanal según temperatura y tiempo. Materiales y métodos: Se realizó su limpieza y desinfección con hipoclorito de sodio (NaOCl) al 4 %, se procedió con apertura cameral, preparación biomecánica e irrigación final con hipoclorito de sodio (NaOCl) al 2,5 % y EDTA 17 % activándolo manualmente con un cono de gutapercha Nº 40 a 100 ciclos en 1 minuto. Se dividieron los treinta premolares monorradiculares en 3 intervenciones de irrigaciones diferentes usando solución salina a temperatura ambiente para el grupo control (GC), solución salina a temperatura 1.5 C° para el grupo 1 (G1), y solución salina a temperatura 4 C° para el grupo 2 (G2) con registro de temperatura a los 0, 1, 2 y 3 minutos post irrigación final. Resultados: Se encontró reducción térmica significativa en la superficie radicular externa de todos los grupos comparados en los diferentes tiempos y temperaturas criogénicas.
The application of cryotherapy in endodontics consists of irrigation with saline solution at low temperatures with the aim of reducing post-operative pain in root canal treatment. The objective of this study was to compare the thermal reduction of the external root surface through intracanal cryotherapy according to temperature and time. Materials and methods: Cleaning and disinfection was carried out with 4 % sodium hypochlorite (NaOCl), proceeded with chamber opening, biomechanical preparation and final irrigation with 2.5 % sodium hypochlorite (NaOCl) and 17 % EDTA, activating it manually with a gutta-percha cone No. 40 to 100 cycles in 1 minute. The thirty single-root premolars were divided into 3 different irrigation interventions using saline solution at room temperature for the control group (CG), saline solution at a temperature of 1.5 C° for group 1 (G1), and saline solution at a temperature of 4 C° for group 2 (G2) with temperature recording at 0, 1, 2 and 3 minutes after final irrigation. Results: Significant thermal reduction was found in the external root surface of all groups compared at different cryogenic times and temperatures.

Abstract Introduction: Low-dose ketamine infusions have shown analgesic effectiveness for the management of postoperative pain. The impact of low-dose ketamine infusions on cardiovascular response is dose-dependent and requires a better knowledge about its effects on this population. Objective: To conduct a systematic review to describe changes in systolic, diastolic and mean arterial pressure, and heart rate 24, 48 and 72 hours after surgery. Methods: Randomized, controlled trials were reviewed in the Cochrane Library, PubMed, EMBASE, SciELO, Lilacs and grey literature on low-dose ketamine infusions for the study variables. The quality of the studies was assessed using the Cochrane's risk of bias tool. Results: Six randomized, controlled trials with 641 patients were included. Low-quality evidence was found suggestive of a lack of certainty of any significant differences in the systolic blood pressure variables at 24 hours (mean standard deviation -1.00, 95 % CI: -7.27 to 5.27). A statistically significant higher mean heart rate at 24 hours was identified in the low-dose ketamine infusion group, (mean standard deviation 1.64 95 % CI: 0.38 to 2.90) which did not reach clinical significance. A lower pain level and less use of opioids was identified in the low-dose ketamine infusion group. Conclusions: Low quality evidence was found, suggesting that low-dose ketamine infusions are not associated with significant changes in blood pressure or heart rate 24 - 48 hours after surgery. It is important to individualize cardiovascular risk for each case, before initiating treatment.
Resumen Introducción: Las infusiones en dosis bajas de ketamina han mostrado eficacia analgésica en el manejo del dolor posoperatorio. El impacto de las infusiones en dosis bajas de ketamina en la respuesta cardiovascular es dosisdependiente y requiere un mejor conocimiento de sus efectos en esta población. Objetivo: Realizar una revisión sistemática para describir los cambios en la presión arterial sistólica, presión arterial diastólica, presión arterial media, frecuencia cardiaca a las 24, 48 y 72 horas del posoperatorio. Métodos: Se revisaron ensayos controlados aleatorizados en Cochrane Library, PubMed, EM-BASE, SciELO, Lilacs y literatura gris de infusiones en dosis bajas de ketamina para las variables del estudio. La calidad de los estudios se evaluó usando la herramienta de riesgo de sesgos de Cochrane. Resultados: Se incluyeron seis ensayos controlados aleatorizados con 641 pacientes. Se encontró evidencia de baja calidad sugestiva de ausencia de certeza de diferencias significativas en las variables presión arterial sistólica a las 24 horas (diferencia de medias estandarizada -1,00, IC95 %: -7,27 a 5,27). Para las 24 horas se halló una media de frecuencia cardiaca mayor en el grupo de infusiones en dosis bajas de ketamina, estadísticamente significativa (diferencia de medias estandarizada 1,64 IC95 %: 0,38 a 2,90) sin alcanzar significancia clínica. Se encontró menor nivel de dolor y consumo de opioides en el grupo de infusiones en dosis bajas de ketamina. Conclusiones: Se encontró evidencia de baja calidad, sugestiva de que las infusiones en dosis bajas de ketamina no se asocian a cambios significativos en la presión arterial o frecuencia cardiaca a las 24-48 horas en el posoperatorio. Es importante individualizar el riesgo cardiovascular para cada caso previo al inicio del tratamiento.

Resumen: Introducción: Aunque existen elementos para guiar la analgesia en el transoperatorio, no hay una herramienta estandarizada que además sea predictora de dolor en el postoperatorio. El Surgical Pleth Index (SPI) podría ser esa prueba diagnóstica. Objetivo: Establecer un valor de corte para SPI para predecir el dolor postoperatorio de moderado a intenso. Material y métodos: Fueron evaluados 60 pacientes, sometidos a cirugía programada con anestesia general balanceada. Las variables analizadas: frecuencia cardíaca, presión arterial media y entropía de estado (SE) se registraron cada dos minutos durante los últimos 10 minutos de la cirugía y al despertar. Durante la recuperación, se midió el dolor postoperatorio mediante la escala numérica análoga (ENA), cada tres minutos durante 15 minutos. Resultados: Se analizaron los datos obtenidos mediante una curva ROC que reveló un valor de corte óptimo intraoperatorio de 36 SPI discriminando entre pacientes sin dolor o dolor leve (ENA = 0-3) vs pacientes con dolor moderado a severo (ENA = 4-10) en el postoperatorio. Para este valor corte, tanto el valor predictivo negativo, como el valor predictivo positivo, fueron altos, (80 y 88.7%, respectivamente). Conclusiones: Un valor de SPI de 36 puede ser un predictor útil de dolor postoperatorio, con mayor efectividad que las variables hemodinámicas analizadas.
Abstract: Introduction: Although there are elements to guide intraoperative analgesia, there is no standardized tool that is also a predictor of postoperative pain. Surgical Pleth Index (SPI) could be that diagnostic test. Objective: To establish a cut-off value for SPI to predict moderate to severe postoperative pain. Material and methods: 60 patients who underwent elective surgery with balanced general anesthesia were evaluated. The analyzed variables: heart rate, mean arterial pressure and state entropy (SE) were recorded every 2 minutes during the last 10 minutes of surgery and upon awakening. During recovery, postoperative pain was measured using the numerical rating scale (NRS) every 3 minutes for 15 minutes. Results: The data obtained were analyzed using a ROC curve that revealed an optimal intraoperative cut-off value of 36 SPI, discriminating between patients without pain or mild pain (NRS = 0-3) vs patients with moderate to severe pain (NRS = 4-10) in the postoperative period. For this cut-off value, both the negative predictive value and the positive predictive value were high (80 and 88.7%, respectively). Conclusions: An SPI value of 36 can be a useful predictor of postoperative pain, with greater effectiveness than the hemodynamic variables analyzed.

Background: Pain in the postoperative period is of particular concern. It is a major barrier in the uptake of circumcision. There are various systemic and local analgesics for the management of postoperative pain. However, data regarding efficacy is scarce. Therefore, the present pilot study was conducted to compare the efficacy of lidocaine and prilocaine spray with oral analgesics for the relief of pain. Methods: After obtaining ethics approval and written informed consent, 100 patients meeting the inclusion and exclusion criteria were included. After circumcision, patients were randomized into group A (Lidocaine and prilocaine spray) and group B (Oral analgesics). Pain was assessed by visual analogue scale (VAS) score and patient reported comfort levels were assessed in the postoperative period till 72 hours. Findings were noted and analysed. Results: Both the groups were similar in terms of demographic characteristics and baseline characteristics. The VAS score was significantly lower in group A and the patient-reported comfort level was significantly more in group A. Conclusions: We recommend that the lidocaine and prilocaine spray is better in relieving pain in the postoperative period following circumcision as compared to oral analgesics.

ObjectiveTo investigate the role of proinflammatory cytokines tumor necrosis factor alpha （TNFα） and interleukin-1β （IL-1β） in rostral ventromedial medulla （RVM） in chronic postsurgical pain （CPSP） induced by skin/muscle incision and retraction （SMIR）. MethodsSD rats were randomly divided into 5 groups： ① Sham group； ② SMIR group； ③ SMIR+TNFα/IL-1β neutralizing antibody group； ④ SMIR+TNFα/IL-1β group and ⑤ SMIR+vehicle group. 50% paw mechanical withdrawal threshold （MWT） was measured by the up-down method， immunofluroscence was used to detect the TNFα and IL-1β expression and ELISA for the 5-Hydroxytryptamine （5-HT） level. ResultsSMIR elicited persistent nociceptive sensitization， upregulated TNFα and IL-1β expression in RVM neurons and astrocytes. Microinjection of TNFα or IL-1β neutralizing antibody into RVM inhibited the development of nociceptive sensitization and decreased the level of 5-HT in both RVM and spinal dorsal horn. While microinjection of recombinant TNFα or IL-1β into RVM enhanced the development of nociceptive sensitization and increased the level of 5-HT in both RVM and spinal dorsal horn. ConclusionUp-regulation of proinflammatory cytokines in RVM may contribute to SMIR induced CPSP by promoting 5-HT release.

Abstract Objective We aimed to investigate the effect of bilateral sphenopalatine ganglion blockade (SPGB) on the main postoperative complications in septorhinoplasty operations. Methods In this randomized, controlled, prospective study, 80 cases planned for Septorhinoplasty operations under general anesthesia were included in the study. The cases were divided into two groups; SPGB was performed with 2 mL of 0.25% bupivacaine bilaterally 15 min before the end of the operation in the SPGB group (Group S, n = 40). In the control group (Group C, n = 40), 2 mL of 0.9% NaCl solution was applied into both SPG areas. In the recovery unit after the operation; the pain and analgesic needs of the patients at 0, 2, 6 and 24 h were evaluated. Results There was no statistically significant difference between the groups in terms of hemodynamic parameters (ASA, MBP, HR) (p> 0.05) All VAS values were statistically lower in Group S than in Group C (p< 0.05). In Group S, the need for analgesic medication was found in 5 cases between 0-2 h, whereas in Group C, this rate was found in 17 cases, and it was statistically significant (p< 0.05). Conclusion Bilateral SPGB application was determined to provide better analgesia in the early postoperative period compared to the control group, it was concluded that further studies are needed to say that there are significant effects on laryngospasm and nausea-vomiting. Level of evidence: 2, degree of recommendation B.

SUMMARY OBJECTIVE: Erector spinae plane block is an updated method than paravertebral block, possessing a lower risk of complications. This study aimed to compare erector spinae plane and paravertebral blocks to safely reach the most efficacious analgesia procedure in laparoscopic cholecystectomy cases. METHODS: The study included 90 cases, aged 18-70 years, classified as American Society of Anesthesiologists I-II, who underwent an laparoscopic cholecystectomy procedure. They were randomly separated into three groups, namely, Control, erector spinae plane, and paravertebral block. No block procedure was applied to Control, and a patient-controlled analgesia device was prepared containing tramadol at a 10 mg bolus dose and a 10-min locked period. The pain scores were recorded with a visual analog scale for 24 h postoperatively. RESULTS: The visual analog scale values at 1, 5, 10, 20, and 60 min at rest and 60 min coughing were found to be significantly higher in Control than in paravertebral block. A significant difference was revealed between Control vs. paravertebral block and paravertebral block vs. erector spinae plane in terms of total tramadol consumption (p=0.006). Total tramadol consumption in the first postoperative 24 h was significantly reduced in the paravertebral block compared with the Control and erector spinae plane groups. CONCLUSION: Sonography-guided-paravertebral block provides sufficient postoperative analgesia in laparoscopic cholecystectomy surgery. Erector spinae plane seems to attenuate total tramadol consumption.

SUMMARY OBJECTIVE: A new block, namely, modified thoracoabdominal nerves block through perichondrial approach, is administered below the costal cartilage. We sought to compare the analgesic efficacy of the modified thoracoabdominal nerves block through perichondrial approach block with local anesthetic infiltration at the port sites in an adult population who underwent laparoscopic cholecystectomy. METHODS: Patients who will undergo laparoscopic cholecystectomy were randomized to receive bilateral ultrasound-guided modified thoracoabdominal nerves block through perichondrial approach blocks or local anesthetic infiltration at the port insertion sites. The primary outcome was the total amount of tramadol used in the first 12 h postoperatively. The secondary outcomes were total IV tramadol consumption for the first postoperative 24 h and visual analog scale scores. RESULTS: The modified thoracoabdominal nerves block through perichondrial approach group had significantly less tramadol use in the first 12 h postoperatively (p<0.001). The modified thoracoabdominal nerves block through perichondrial approach group's visual analog scale scores at rest (static) and with movement (dynamic) were significantly lower compared with the port infiltration group (p<0.05). CONCLUSION: Patients who received modified thoracoabdominal nerves block through perichondrial approach block had significantly less analgesic consumption and better pain scores than those who received port-site injections after laparoscopic cholecystectomy.

ABSTRACT Introduction: It is not yet clear whether cardiac surgery by mini-incision (minimally invasive cardiac surgery [MICS]) is overall less painful than the conventional approach by full sternotomy (FS). A meta-analysis is necessary to investigate polled results on this topic. Methods: PubMed®/MEDLINE, Cochrane CENTRAL, Latin American and Caribbean Health Sciences Literature (or LILACS), and Scientific Electronic Library Online (or SciELO) were searched for all clinical trials, reported until 2022, comparing FS with MICS in coronary artery bypass grafting (CABG), mitral valve surgery (MVS), and aortic valve replacement (AVR), and postoperative pain outcome was analyzed. Main summary measures were the method of standardized mean differences (SMD) with a 95% confidence interval (CI) and P-values (considered statistically significant when < 0.05). Results: In AVR, the general estimate of postoperative pain effect favored MICS (SMD 0.87 [95% CI 0.04 to 1.71], P=0.04). However, in the sensitivity analysis, there was no difference between the groups (SMD 0.70 [95% CI -0.69 to 2.09], P=0.32). For MVS, it was not possible to perform a meta-analysis with the included studies, because they had different methodologies. In CABG, the general estimate of the effect of postoperative pain did not favor any of the approaches (SMD -0.40 [95% CI -1.07 to 0.26], P=0.23), which was confirmed by sensitivity analysis (SMD -0.02 [95% CI -0.71 to 0.67], P=0.95). Conclusion: MICS was not globally less painful than the FS approach. It seems that postoperative pain is more related to the degree of tissue retraction than to the size of the incision.

Postoperative pain is a frequent complication after root canal treatment. Its management is an important aspect of endodontic practice. Some treatment-related parameters were associated with the development of postoperative pain, including the sealer composition and extrusion. Objective: This systematic review aimed to answer the clinical question: Do root canal sealers composition influence postoperative pain after endodontic treatment of permanent teeth? Material and Methods: Electronic searches were conducted in PubMed, Scopus, Web of Science, Cochrane, LILACS, and grey literature databases until September 2021. The studies were qualitatively assessed using the RoB2 tool (Cochrane) and the certainty of evidence (GRADE). Sensitivity and pooled estimates were calculated using a random-effects model. Twelve articles were included. Results: The risk of bias was high in one study, low in nine, and two had some concerns. Qualitative analyses showed no influence of sealer extrusion on postoperative pain. Meta-analyses showed no significant difference in postoperative pain with moderate to very low levels of certainty between AH Plus and calcium silicate-based sealers, in a 95% confidence interval. Analysis between AH Plus, Zinc Oxide and Eugenol (ZOE), and calcium hydroxide (Ca(OH)2)-based sealers were not performed due to heterogeneity and lack of data. Conclusion: Literature showed contrasting results in postoperative pain between AH Plus and ZOE-based sealers, with low to moderate certainty of evidence. Regarding Ca(OH)2-based sealers, a single study with a low level of certainty concluded that AH Plus presented less postoperative pain than Apexit Plus. Therefore, further studies are needed to assess the influence of these sealers on postoperative pain. Evidence showed no difference in postoperative pain between AH Plus and calcium silicate-based sealers. Sealer extrusion is a variable that requires further studies (AU)
A dor pós-operatória é uma complicação frequente após o tratamento endodôntico. O seu manejo é um importante aspecto na prática endodôntica. Algumas variáveis relacionados ao tratamento foram associados com o desenvolvimento da dor pós-operatória, incluindo a composição e extrusão dos cimentos endodônticos. Objetivo: Esta revisão sistemática objetivou responder a seguinte pergunta clínica: A composição dos cimentos endodônticos podem influenciar a dor pós-operatória de dentes permanentes tratados endodonticamente?Material e Métodos: Buscas eletrônicas foram realizadas nas bases de dados no PubMed, Scopus, Web of Science, Cochrane, LILACS, e literatura cinzenta até setembro de 2021. Os estudos foram avaliados qualitativamente usando a ferramenta RoB2 (Cochrane) e a certeza de evidência (GRADE). A sensibilidade e as estimativas agrupadas foram calculadas usando um modelo de efeitos aleatórios. Doze artigos foram incluídos. Resultados: O risco de viés foi alto em um estudo, baixo em nove e dois tiveram algumas preocupações. A análise qualitativa mostrou que não há influência da extrusão do cimento na dor pós-operatória. A meta-análise mostrou que não houve diferença estatisticamente significante na dor pós-operatória entre o AH Plus e os cimentos a base de silicato de cálcio com moderada a muito baixa certeza de evdência. Análises entre os cimentos AH Plus, óxido de zinco e eugenol (OZE) e hidróxido de cálcio não foram realizados devido a heterogeneidade e falta de dados. Conclusão:A literatura sugere resultados contrastantes com relação a dor pós-operatória e entre os cimentos AH Plus e OZE, com baixa a moderada certeza de evidência. Já os cimentos a base de hidróxido de cálcio, um único estudo com baixa certeza de evidência concluiu que o AH Plus apresentou menos dor pós tratamento endodôntico do que o Apexit Plus. Portanto,mais estudos são necessários para avaliar a influência desses tipos de cimentos na dor pós-operatória. Com relação ao cimento AH Plus e os cimentos a base de silicato de cálcio não houve diferença estatística entre eles e a dor. A extrusão dos cimentos é uma variável que requer mais estudos (AU)

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.

Abstract Pain is the most common complaint reported to orthopedists in the outpatient clinic, emergency room, or booth. Numerous publications report the inadequate management of both acute and chronic pain by health professionals. This updated article aims to provide information about musculoskeletal pain, its classification, evaluation, diagnosis, and the multimodal therapeutic approach for each case. For acute pain, adequate control allows for earlier rehabilitation to work and reduces the rates of pain chronification. For chronic pain, the goal is to reduce its intensity and improve the quality of life. Currently, some procedures are increasingly used and aided by imaging tests for diagnostic and therapeutic purposes.
Resumo A dor é a queixa mais comum recebida pelo ortopedista no ambulatório e/ou emergência. Inúmeras publicações relatam o manejo inadequado tanto da dor aguda quanto da dor crônica pelos profissionais da saúde. O objetivo desse artigo de atualização é trazer informações sobre a dor musculoesquelética, sua classificação, avaliação, diagnóstico e abordagem terapêutica multimodal para cada situação. Desta maneira, nas dores agudas seu controle adequado possibilita um trabalho de reabilitação mais precoce, bem como diminui os índices de cronificação da dor. Nas dores crônicas sua abordagem além da diminuição de sua intensidade, visa também melhorar a qualidade de vida. Atualmente alguns procedimentos estão sendo cada vez mais utilizados com auxílio de aparato de imagem com objetivo diagnóstico e terapêutico.

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.

Resumen: Introducción: contar con una analgesia efectiva en el postoperatorio es fundamental para evitar complicaciones asociadas a dolor, en pacientes sometidos a colecistectomía laparoscópica. Objetivos: evaluar la efectividad de la lidocaína en infusión transoperatoria para el control de dolor postoperatorio en pacientes sometidos a colecistectomía laparoscópica. Material y métodos: se realizó un estudio experimental, aleatorizado, ciego simple, en pacientes sometidos a colecistectomía laparoscópica en el Hospital General Regional No. 1 en Obregón. Se dividieron en dos grupos de forma aleatoria, al grupo L se le aplicó lidocaína 1.5 mg/k en infusión, al grupo P se le aplicó placebo. Se realizó un análisis estadístico en SPSS v. 22 y se consideró significativa una p < 0.05. Resultados: se observó un adecuado manejo del dolor en los pacientes del grupo L a su ingreso a la Unidad de Recuperación Postanestésica (URPA) (p = 0.002), menor consumo de fentanyl transoperatorio sin diferencia estadística contra placebo (p = 0.086), menor uso de analgesia de rescate postquirúrgica (p = 0.045). 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.
