RESUMO

La lidocaína es el anestésico local más utilizado a nivel mundial para la cirugía de catarata. También se usa de manera común en otras intervenciones quirúrgicas oftalmológicas del segmento anterior, la superficie del globo ocular, los párpados y vías lagrimales, así como en el segmento posterior del ojo. Esta revisión pretende brindar una actualización sobre las principales características, los efectos y vías de administración de la lidocaína usada en la oftalmología. Se realizó una búsqueda sistemática sobre el tema en publicaciones científicas indexadas en bases de datos, cuya información recopilada se resumió en este trabajo. La lidocaína se presenta en múltiples formas farmacéuticas, con variedad en concentración y formulación. Por lo general, para inyección se usan las concentraciones al 0,5 por ciento, 1 por ciento y 2 por ciento, para anestesia tópica en gel al 2 por ciento y en solución oftálmica al 4 por ciento. Su efecto como anestésico local es bien conocido, a nivel ocular se puede conseguir a través de inyecciones perioculares e intraoculares o mediante su aplicación tópica. Este efecto anestésico de la lidocaína ofrece cierta capacidad de dilatación pupilar, el cual se ha estudiado y aprovechado con frecuencia en los últimos años. Hoy día se encuentran en estudio otros efectos de la lidocaína a nivel local y sistémico. Los usos de la lidocaína en la oftalmología actual, están respaldados fundamentalmente por su eficacia y seguridad comprobadas en el tiempo(AU)


Lidocaine is the most widely used local anesthetic worldwide for cataract surgery. It is also commonly used in other ophthalmic surgical procedures of the anterior segment, surface of the eyeball, eyelids and lacrimal ducts, as well as in the posterior segment of the eye. This review aims to provide an update on the main characteristics, effects and ways of administering lidocaine used in ophthalmology. A systematic search on the subject was carried out in scientific publications indexed in databases, the information collected was summarized in this work. Lidocaine comes in multiple pharmaceutical forms, with a variety of concentrations and formulations. Generally, 0.5 percent, 1 percent and 2 percent concentrations are used for injection, 2 percent for topical anesthesia in gel and 4% in ophthalmic solution. Its effect as a local anesthetic is well known, at ocular level it can be achieved through periocular and intraocular injections or by topical application. This anesthetic effect of lidocaine offers some pupillary dilation capacity, which has been frequently studied and exploited in recent years. Other local and systemic effects of lidocaine are currently under study. The uses of lidocaine in ophthalmology today are supported primarily by its time-tested efficacy and safety(AU)

RESUMO

Abstract Objective: To evaluate the efficacy and safety of trans-nasal Sphenopalatine Ganglion (SPG) block over other treatments for Post-Dural Puncture Headache (PDPH) management. Methods: A systematic literature search was conducted on databases for Randomized Controlled Trials (RCTs) comparing trans-nasal SPG blockade for the management of PDPH over other treatment modalities. All outcomes were pooled using the Mantel-Haenszel method and random effect model. Analyses of all outcomes were performed as a subgroup based on the type of control interventions (conservative, intranasal lignocaine puffs, sham, and Greater Occipital Nerve [GON] block). The quality of evidence was assessed using the GRADE approach. Results: After screening 1748 relevant articles, 9 RCTs comparing SPG block with other interventions (6 conservative treatments, 1 sham, 1 GON and 1 intranasal lidocaine puff) were included in this meta-analysis. SPG block demonstrated superiority over conservative treatment in pain reduction at 30 min, 1 h, 2 h, 4 h after interventions and treatment failures with "very low" to "moderate" quality of evidence. The SPG block failed to demonstrate superiority over conservative treatment in pain reduction beyond 6 h, need for rescue treatment, and adverse events. SPG block demonstrated superiority over intranasal lignocaine puff in pain reduction at 30 min, 1 h, 6 h, and 24 h after interventions. SPG block did not show superiority or equivalence in all efficacy and safety outcomes as compared to sham and GON block. Conclusion: Very Low to moderate quality evidence suggests the superiority of SPG block over conservative treatment and lignocaine puff for short-term pain relief from PDPH.

RESUMO

La exodoncia de los terceros molares inferiores es uno de los procedimientos clínicos más comunes en el cual el control del dolor mediante el bloqueo anestésico del nervio alveolar inferior, bucal y lingual resulta ser fundament al y la manera más común de hacerlo es mediante la infiltración de soluciones de anestesia local. Entre ellos la lidocaína y articaína son algunos de los más comunes y pueden estar asociado a vasoconstrictores como la epinefrina que puede provocar aumento de la presión arterial y frecuencia cardíaca razón por la cual se hace necesario la monitorización de cambios hemodinámicos durante la cirugía. Describir los cambios hemodinámicos asociados al uso de lidocaína al 2 % y/ o articaína al 4 % en la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en relación a distintos tiempos operatorios. Se realizó una revisión sistemática en las bases de datos de PubMed, SCOPUS, Web of Science y Sciencedirect. Se analizaron 7 ensayos clínicos controlados en los que utilizaron articaína al 4 % y/o lidocaína al 2 % con epinefrina al 1:100,000 y/o 1:200,000 en volúmenes de 1,8 a 5,4 mL, en los cuales evaluaron la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en distintos tiempos de la cirugía. Si bien hubo cambios en PAS, PAD, FC y SPO2, todas se mantuvieron dentro de rangos normales bajo el uso de articaína al 4 % y lidocaína al 2 % con epinefrina 1:100,000 y/o 1:200,000 a volúmenes de 1,8 a 5,4mL medidas a distintos tiempos operatorios.


The extraction of lower third molars is one of the most common clinical procedures in which pain control through anesthetic blockade of the lower alveolar, buccal and lingual nerves turns out to be essential and the most common way to do it is through the infiltration of solutions of local anesthesia. Among them, lidocaine and articaine are some of the most common and may be associated with vasoconstrictors such as epinephrine, which can cause an increase in blood pressure and heart rate, which is why it is necessary to monitor hemodynamic changes during surgery. To describe the hemodynamic changes associated with the use of 2 % lidocaine and/or 4 % articaine in systolic and diastolic pressure, heart rate and partial oxygen saturation in relation to different operative times. A systematic review was carried out in the PubMed, SCOPUS, Web of Science and Sciencedirect databases. Seven controlled clinical trials were analyzed in which 4 % articaine and/or 2 % lidocaine were used with epinephrine at 1:100,000 and/or 1:200,000 in volumes of 1,8 to 5,4 mL, in which systolic pressure was evaluated. and diastolic, heart rate and partial oxygen saturation at different times of surgery. Although there were changes in SBP, DBP, HR and SPO2, all remained within normal ranges under the use of 4 % articaine and 2 % lidocaine with epinephrine 1:100,000 and/or 1:200,000 at volumes of 1,8 to 5 .4mL measured at different operative times.

RESUMO

Abstract Stenting for lower tracheal stenosis is a tricky situation and for the safe conduct of anesthesia, it is imperative to maintain spontaneous respiration. Airway topicalization is routinely recommended for anticipated difficult airway. We report a case of upper airway obstruction following lidocaine nebulization in a patient to be taken for tracheal stenting for lower tracheal stenosis. We would like to highlight that close monitoring of the patient is advisable during airway topicalization to detect any airway obstruction at the earliest and how fiberoptic intubation can play a pivotal role to secure the airway in an emergency scenario.

RESUMO

ABSTRACT Objective: To evaluate the feasibility of posterior maxillary teeth extraction buccal infiltration with or without the use of palatal injection. Material and Methods: A total of 70 patients underwent extraction of bilateral maxillary posterior teeth under 2% lignocaine hydrochloride with 1:2,00000 adrenaline infiltration in this single-centric split-mouth randomized trial. The test side was administered with a buccal infiltration of 2 mL of anesthetic alone. An extended waiting period of 10 minutes was given before the commencement of the procedure. A standard protocol was followed for the control side. A single operator performed all extractions. Results: A total of 140 posterior maxillary teeth were extracted. Patients marked pain perception on a visual analogue scale in three different instances. During the administration of injections for the test side, the pain score was less than that of the control side and was statistically significant. The overall pain during the extraction procedure was comparable and statistically insignificant. The overall success of the method was 90%. Conclusion: Extraction of posterior maxillary teeth was feasible with a single buccal infiltration without palatal injection in most cases using an extended waiting period. Dentists can attempt extraction without palatal injections with optimal success. However, the alternate technique could be used when there is a necessity for rescue palatal anesthesia.

RESUMO

Purpose: The primary objective of this study was to compare the WALANT (wide awake, local anesthesia, no tourniquet) technique with local anesthesia associated with sedation in relation to pain intensity for minor hand surgical procedures. The secondary objective was to evaluate the need for analgesic complementation. Methods: A prospective, randomized, comparative, and clinical study was carried out. The sample size in each group was determined after statistical evaluation of the results of a pilot project. The participants were allocated to one of two groups; those in group 1 were submitted to the WALANT technique, and those in group 2, to local anesthesia associated with sedation, for elective surgery. The surgical procedures were carpal tunnel syndrome, De Quervain's tenosynovitis, synovial cyst, finger cyst, and trigger finger. Pain intensity, need for complementation and evolution to complex regional pain syndrome were evaluated. Results: There was no difference between groups in pain intensity after WALANT and need for intraoperative complementation. There was no significant difference in the amount of opioid applied postoperatively between the groups. There was no difference between groups regarding comfort during surgery. There was no difference in adverse effects and complications between the groups. Hematoma was the most frequent adverse event. No severe adverse events were observed. Conclusions: The WALANT technique promoted an analgesic effect similar to that of local anesthesia associated with sedation, without increasing adverse effects.

Background: We present the description of a supramalleolar ankle block technique and our experience using this technique in foot and ankle surgery. Materials and methods: We performed a retrospective observational study of the past 5 years of patients with foot and ankle pathology that had undergone the supramalleolar ankle block. We excluded patients with a history of previous foot surgery, bilateral surgeries, vascular disease, peripheral neuropathy, diabetes, smoking, or active surgical site infection. The supramalleolar ankle block was guided by anatomic landmarks and we used a solution of lidocaine 2% and bupivacaine 0.5%. We evaluated the duration of the ankle block, the visual analog scale (VAS) for pain 24 hrs after surgery, the time until the first analgesic dose, and the level of patient satisfaction. Results:771 patients were included in this study, all of whom had complete analgesia for at least 12 hrs (mean 18 hrs) after surgery. The mean value on the VAS for pain after 24 hrs was 1.4. On average, the first analgesic dose was administered 16 hrs after surgery. The level of satisfaction about the pain perceived in the first 24 hrs after surgery was: very satisfied (89%), satisfied (10%), and dissatisfied (1%). There were no reports of permanent neurological sequelae, systemic toxicity, or surgical site infections. Conclusion: We consider the supramalleolar ankle block a simple, effective, and safe procedure to obtain long-lasting postoperative analgesia. Level of Evidence: IV

RESUMO

Abstract Introduction Burns are a common trauma that cause acute severe pain in up to 80% of patients. The objective of this narrative review is to evaluate the efficacy of opioids, non-steroidal anti-inflammatory drugs, paracetamol, gabapentinoids, ketamine, and lidocaine in the treatment of acute pain in burn victims. Methodology The databases explored were PubMed, Embase, ClinicalTrials, and OpenGrey. The included randomized, controlled clinical trials assessed the analgesic efficacy of these drugs on hospitalized patients, had no age limit, patients were in the acute phase of the burn injury and were compared to placebo or other analgesic drugs. Studies describing deep sedation, chronic opioid use, chronic pain, and patients taken to reconstructive surgeries were excluded. The Jadad scale was used to evaluate quality. Results Six randomized controlled clinical trials (397 patients) that evaluated the analgesic efficacy of fentanyl (n = 2), nalbuphine (n = 1), ketamine (n = 1), gabapentin (n = 1), and lidocaine (n = 1) to treat post-procedural pain were included. Fentanyl, nalbuphine, and ketamine were effective, while lidocaine was associated with a slight increase in reported pain and gabapentin showed no significant differences. Two studies were of high quality, one was of medium high quality, and three were of low quality. No studies on the efficacy of NSAIDs or paracetamol were found. Conclusion Evidence of efficacy is very limited. Fentanyl, nalbuphine, and ketamine seem to be effective for controlling acute pain in burn patients, whereas gabapentin and lidocaine did not show any efficacy.

RESUMO

Abstract Background: Acute postoperative pain is associated with poor quality of recovery after surgery. Perioperative use of intravenous lignocaine or dexmedetomidine have demonstrated better pain control, early return of bowel function, and effects on quality of recovery. Methods: Ninety-six women planned for elective robotic abdominal hysterectomy were randomized into four groups. Groups received lignocaine infusion (1.5 mg.kg−1 loading, 2 mg.kg−1.h−1 infusion) (Group I), dexmedetomidine infusion (1 µg.kg−1 loading, 0.6 µg.kg−1.h−1 infusion) (Group 2), lidocaine (1.5 mg.kg−1 loading, 2 mg.kg−1.h−1 infusion), and dexmedetomidine infusions (1 µg.kg−1 loading, 0.5 µg.kg−1.h−1 infusion) (Group 3), and normal saline 10 mL loading, 1 mL.kg−1.h−1 infusion) (Group 4). Primary outcome was visual analogue pain scores at 1, 2, 4, 12, and 24 hours after surgery. Secondary outcomes included postoperative fentanyl requirement, time of return of bowel sounds and flatus, QoR15 score on day 1, 2, and discharge. Results The VAS was significantly lower in Groups 2 and 3 compared to Groups 1 and 4. Total postoperative fentanyl consumption in the first 24 hours was 256.25 ± 16.36 mcg (Group 1), 177.71 ± 16.81 mcg (Group 2), 114.17 ± 16.19 mcg (Group 3), and 304.42 ± 31.26 mcg (Group 4), respectively. Time to return of bowel sounds and passage of flatus was significantly shorter in Groups 2 and 3 (p < 0.01). QoR15 scores after surgery were higher in Group 3 compared to Groups 1, 2, and 4, (p < 0.01) respectively. Conclusion: Combined infusion of lignocaine and dexmedetomidine significantly decreased postoperative pain, fentanyl consumption, and improved quality of recovery score after surgery in patients undergoing Robotic abdominal hysterectomy.

RESUMO

Introducción: La cirugía de la hernia inguinal constituye uno de los procederes más comunes a nivel mundial. Se estima que el 80 por ciento son realizados con anestesia regional o general, y un 20 por ciento con local en contra de la recomendación de las sociedades internacionales que aceptan que la mayor parte de los enfermos son candidatos para este método. Objetivos: Describir la técnica de anestésica local aplicada por el propio cirujano, exponiendo sus ventajas y desventajas apoyadas en la evidencia relevante disponible. Métodos: Se realizó una revisión híbrida de tipo narrativa. Se describió el método anestésico empleado por nuestro grupo. Paralelamente, se realizó una búsqueda en las principales bases de datos para la identificación de las investigaciones que sostienen y defienden los aspectos técnicos y decisiones clínicas tomadas. Desarrollo: No existen contraindicaciones absolutas para la selección de la anestesia local, en su mayoría son relativas. El anestésico a emplear es lidocaína, aunque adjuvantes pueden ser tenidos en cuenta. La sedación pre o transoperatoria no se recomienda. El método anestésico involucra la fase subcutánea con una técnica de bloqueo de campo y fase incisional profunda con infiltración tumescente. Conclusiones: El empleo de anestesia local para la cirugía de hernia inguinal por vía anterior puede ser considerado de primera elección. Es más económica y las complicaciones urinarias y cardiovasculares se reducen. Para lograr una cirugía de igual calidad a otro método de anestesia es importante dominar la técnica anestésica(AU)


Introduction: Inguinal hernia surgery is one of the most common procedures worldwide. 80 percent of them are estimated to be performed under regional or general anesthesia; while 20 percent are performed under local anesthesia, contrary to the recommendation of international societies, which accept that most of the patients are candidates for this method. Objectives: To describe the local anesthetic technique applied by the surgeon himself, exposing its advantages and disadvantages supported by the relevant evidence available. Methods: A hybrid narrative review was carried out. The anesthetic method used by our group was described. At the same time, a search was performed in the main databases to identify the research supporting and defending the technical aspects and the taken clinical decisions. Development: There are no absolute contraindications for the selection of local anesthesia; most of them are relative. The anesthetic to be used is lidocaine, although adjuvants can be taken into account. Pre- or intraoperative sedation is not recommended. The anesthetic method involves the subcutaneous phase with a field block technique and the deep incisional phase with tumescent infiltration. Conclusions: The use of local anesthesia for inguinal hernia surgery though an anterior approach can be considered as the first choice; it is more economical, while urinary and cardiovascular complications are reduced. To achieve a surgery of equal quality to another method of anesthesia, it is important to master the anesthetic technique(AU)

RESUMO

Aim: To investigate the precipitate formed from the interaction between 2% lidocaine hydrochloride with adrenaline (LA) with 2.5% sodium hypochlorite (NaOCl) and 0.2% chitosan nanoparticles on root canal dentin, using scanning electron microscopy (SEM). Material and Methods: Sixty mandibular premolars were decoronated, and the root length standardised. The specimens were randomly distributed into the following groups: Group 1 (control): 2% LA mixed with sterile water without root canal instrumentation, Group 2: 2% LA with 2.5% NaOCl in water without root canal instrumentation, and Group 3: 2% LA with 0.2% chitosan nanoparticles in water without root canal instrumentation. Teeth specimens were split and subjected to SEM analysis at cervical, middle, and apical root thirds. On observing precipitate formation in Group 2, 10 premolars were decoronated and treated with 2% LA and 2.5% NaOCl and subjected to root canal instrumentation. Results: Group 1 and Group 3 showed patent dentinal tubules and no precipitate formation. Group 2 showed precipitate blocking dentinal tubules in all the three sections, and the precipitate could not be removed completely after cleaning and shaping. Conclusion: NaOCl forms an insoluble precipitate on interaction with local anaesthetic solution that cannot be removed after chemo-mechanical preparation. Chitosan nanoparticles do not form any such precipitate and show patent dentinal tubules. Hence, chitosan can be used as a flushing irrigant.


Objetivo: Investigar el precipitado formado a partir de la interacción entre el clorhidrato de lidocaína al 2% con adrenalina (LA), el hipoclorito de sodio al 2,5% (NaOCl) y nanopartículas de quitosano al 0,2% en la dentina del conducto radicular, mediante microscopía electrónica de barrido (SEM). Material y Métodos: Se decoraron 60 premolares mandibulares y se estandarizó la longitud de la raíz. Los especímenes se distribuyeron aleatoriamente en los siguientes grupos: Grupo 1 (control): 2% la que fue mezclado con agua estéril sin instrumentación del conducto radicular, Grupo 2: 2% LA con 2,5% de NaOCl sin instrumentación del conducto radicular y Grupo 3: 2 % LA con 0,2% de nanopartículas de quitosano sin instrumentación del conducto radicular. Las muestras de dientes se dividieron y se sometieron a análisis SEM en los tercios radiculares cervical, medio y apical. Al observar la formación de precipitado en el Grupo 2, 10 premolares fueron decorados y tratados con LA al 2% y NaOCl al 2,5% y sometidos a instrumentación de conductos radiculares. Resultado: El Grupo 1 y el Grupo 3 mostraron túbulos dentinarios permeables y sin formación de precipitados. El grupo 2 mostró precipitado que bloqueaba los túbulos dentinarios en las tres secciones, y el precipitado no se pudo eliminar por completo después de limpieza y conformación. Conclusión: el NaOCl forma un precipitado insoluble al interactuar con la solución anestésica local que no se puede eliminar después de la preparación quimiomecánica. Las nanopartículas de quitosano no forman ningún precipitado de este tipo y muestran túbulos dentinarios permeables. Por lo tanto, el quitosano se puede utilizar como irrigante para el lavado.

RESUMO

Introducción: En los últimos años la anestesia local sin torniquete y con el paciente despierto, técnica conocida por WALANT (por sus siglas en inglés), ha ganado mucha popularidad en las cirugías de la mano y la muñeca. Objetivo: Reportar nuestra experiencia con el uso de la técnica WALANT, a fin de prescindir del uso del torniquete en las cirugías de la mano. Métodos: En noviembre del 2020 fueron intervenidos 30 pacientes por diversas enfermedades ortopédicas, entre las que figuraron: dedos en resorte, síndrome del túnel carpiano, tenovaginitis estenosante del pulgar, gangliones del carpo y amputación del tercer radio por rigidez en extensión postraumática, entre otras. Para la evaluación de la técnica tuvimos en cuenta: tiempo quirúrgico, magnitud del sangrado, dolor durante la infiltración anestésica, la intervención, y en las primeras 24 horas del postoperatorio, la necesidad de refuerzo anestésico, uso de isquemia, complicaciones y nivel de satisfacción del paciente. Resultados: Los resultados obtenidos con esta técnica anestésica son semejantes a otras, con las ventajas que el sangrado es leve, no hay que utilizar isquemia, el tiempo quirúrgico es menor y el efecto anestésico duró entre 10 y 12 horas en todos los pacientes. En ninguno de los pacientes hubo necesidad de refuerzo anestésico. Conclusiones: Se demuestra la efectividad de la técnica WALANT en las cirugías de mano. Con ella se disminuye el gasto de materiales para el acto quirúrgico, así como de personal, es de fácil aplicación y disminuyen las sensaciones desagradables y los peligros del uso de isquemia en los pacientes(AU)


Introduction: Currently, the use of local anaesthetic with no tourniquet and wide awake patient (Wide Awake Local Anaesthetic No Tourniquet - WALANT) has gained popularity in surgeries of the hand and wrist. Objective: To report our experience in the use of WALANT technique in order to discard the use of tourniquet in hand surgeries. Method: In November 2020, thirty patients underwent surgery due to different orthopaedic conditions, among them trigger fingers, carpal tunnel syndrome, stenosing tenovaginitis of the thumb, carpal ganglion and amputation of the third radius due to post trauma stiffness, among others. In order to assess this technique, we considered surgical time, volume of bleeding, pain during anesthetic infiltration, intervention and the need for additional anesthetic during the first 24 hours after surgery; we considered also ischemia, complications and level patient´s satisfaction. Results: This technique had similar results to others; however, the bleeding is mild, there is no need for ischemia, the surgical time is lesser and the anesthetic effect lasted 10 to 12 hours in all patients. None of them required additional anesthetic. All subjects felt the initial infiltration but none complained of pain during the rest of the anesthetic injection or during the surgical act. There were no complications. Conclusions: The effectiveness of WALANT technique in hand surgeries is shown. The cost of materials for the surgical act is reduced with it, as well as the surgical staff, it is easy to use and unpleasant sensations and dangers of the use of ischemia in patients are reduced(AU)

RESUMO

Abstract Introduction: The use of intravenous lidocaine infusion has increased over the past decade as part of a multimodal approach to analgesia in adults; however, information about its safety and tolerability in the pediatric population is limited. Methods: Acute pain management using lidocaine infusion in eleven patients treated in the pediatric intensive care unit. Results: Five cases of postoperative abdominal pain and six cases of non-operative abdominal pain. Two cases were cancer patients affected by neutropenic colitis. Analgesic control achieved was good. Conclusion: Lidocaine infusions are apparently a safe option for the management of acute pain, either post-operative or not, in the pediatric population.


Resumen Introducción: El uso de la infusión de lidocaína endovenosa ha aumentado en la última década como parte de un enfoque analgésico multimodal en los adultos; sin embargo, se dispone de información limitada sobre su seguridad y tolerabilidad en la población pediátrica. Métodos: Se presentan once casos de manejo de dolor agudo con lidocaína en infusión tratados en unidad de cuidado intensivo pediátrico. Resultados: Cinco casos fueron postoperatorio abdominal y seis casos tenían dolor abdominal no postoperatorio. Dos pacientes tenían cáncer y cursaban con colitis neutropénica. El control analgésico alcanzado fue bueno. Conclusión: Las infusiones de lidocaína parecen ser una opción segura para el manejo del dolor agudo ya sea posquirúrgico o no en la población pediátrica.

RESUMO

Objetivo: Evaluar la seguridad ocular y sistémica de una combinación de lidocaína 2 por ciento y fenilefrina 1 por ciento administrada por vía intracameral para provocar midriasis intraoperatoria en la cirugía de catarata. Métodos: Se realizó un estudio prospectivo de serie de casos en 70 ojos de igual número de pacientes sometidos a facoemulsificación con implante de lente intraocular. El grupo midriasis intraoperatoria en la cirugía lo conformaron 35 pacientes dilatados con una inyección intracameral de lidocaína y fenilefrina antes de la cirugía, mientras otros 35 ojos se dilataron de manera tradicional, con un colirio midriático previo. Para la seguridad ocular se evaluaron múltiples parámetros del examen oftalmológico pre- y posoperatorio. Resultados: La presión intraocular, el espesor corneal central, la densidad celular del endotelio corneal y el edema corneal posoperatorio como hallazgo del segmento anterior se comportaron de manera similar en ambos grupos de estudio. Se reportó una complicación transoperatoria en el grupo de manera tradicional y un caso con edema quístico macular posoperatorio en el grupo midriasis intraoperatoria en la cirugía que no representaron diferencias significativas. Conclusión: La inyección de lidocaína más fenilefrina intracameral es una opción segura tanto ocular como sistémica para provocar midriasis durante la facoemulsificación(AU)


Objective: Evaluate the ocular and systemic safety of a combination of 2 percent lidocaine and 1 percent phenylephrine administered intracamerally to achieve intraoperative mydriasis in cataract surgery. Methods: A prospective study was conducted of a case series of 70 patients (70 eyes) who underwent phacoemulsification with intraocular lens implantation. The intraoperative mydriasis group was composed of 35 patients dilated with an intracameral injection of lidocaine and phenylephrine before surgery, whereas another 35 eyes were dilated by the conventional method, with mydriatic eye drops. Ocular safety evaluation was based on the analysis of a wide variety of pre- and postoperative ophthalmological examination parameters. Results: Intraocular pressure, central corneal thickness, corneal endothelial cell density and postoperative corneal edema as an anterior segment finding, behaved in a similar manner in both study groups. An intraoperative complication was reported in the conventional method group and a case with postoperative cystoid macular edema in the intraoperative mydriasis group group, neither of them exhibiting significant differences. Conclusion: Intracameral lidocaine plus phenylephrine injection is a safe ocular and systemic option to achieve mydriasis during phacoemulsification(AU)

RESUMO

Introducción: El estudio y tratamiento del dolor ha sido una de las preocupaciones más importantes en los últimos 30 años en el ámbito médico mundial. Desde hace varias décadas a nivel internacional se realizan estudios sobre el efecto del tramadol y la lidocaína como analgésicos intraoperatorio, con el fin de obtener una adecuada analgesia durante el procedimiento quirúrgico y el periodo posoperatorio inmediato. Objetivo: Comparar el efecto analgésico del tramadol y la lidocaína durante el período transoperatorio en caninos programados para intervención quirúrgica. Método: Se realizó un estudio prospectivo, comparativo, con animales programados para tratamiento quirúrgico por presentar tumores periféricos. Se incluyeron 10 animales divididos en 2 grupos. El grupo control (G-C) que recibió lidocaína sin preservo (lidocaína SP) en infusión continua durante el procedimiento quirúrgico y el grupo 1 (G-1) que se le administró tramadol endovenoso previo al acto quirúrgico. Se evaluaron variables hemodinámicas y de oxigenación como indicadores indirectos de dolor transoperatorio. Resultados: La muestra fue homogénea para la edad y el sexo. El comportamiento de las variables hemodinámicas resultó más estable durante la infusión de lidocaína. La saturación periférica de oxígeno fue similar con ambos medicamentos, así como la temperatura. Conclusiones: La infusión intravenosa de lidocaína SP durante el periodo transoperatorio en caninos oncológico demostró una mejor efectividad analgésica en comparación con el tramadol aplicado preoperatoriamente, según los parámetros evaluados(AU)


Introduction: Study and treatment of pain has been one of the most important concerns in the last thirty years in the worldwide medical field. For several decades, international studies have been carried out on the effect of tramadol and lidocaine as intraoperative analgesics, in order to achieve adequate analgesia during surgical procedures and the immediate postoperative period. Objective: To compare the analgesic effect of tramadol and lidocaine during the intraoperative period in canines scheduled for surgical intervention. Method: A prospective, comparative study was carried out with animals scheduled for surgical treatment due to peripheral tumors. Ten animals were included, divided into two groups: the control group, which received lidocaine without preservation in continuous infusion during the surgical procedure, and group 1, which was administered intravenous tramadol prior to the surgical act. Hemodynamic and oxygenation variables were assessed as indirect indicators of intraoperative pain. Results: The sample was homogeneous for age and sex. The behavior of the hemodynamic variables was more stable during the lidocaine infusion. Peripheral oxygen saturation was similar in both drugs, as well as temperature. Conclusions: Intravenous infusion of lidocaine without preservation during the intraoperative period in oncological canines showed better analgesic effectiveness compared to tramadol applied preoperatively, according to the parameters assessed(AU)

RESUMO

El bloqueo del nervio peri prostático con lidocaína, proporciona un buen alivio del dolor en la realización de la biopsia prostática guiada por ultrasonido, pero el dolor post-procedimiento, puede llegar a ser significativo, la adición del supositorio de diclofenac, podría proporcionar alivio adicional. Se asignaron al azar pacientes en 2 grupos el grupo 1 bloqueo con lidocaína del plexo peri prostático + supositorio de diclofenac sódico y el grupo 2 bloqueo con lidocaína del plexo peri prostático + supositorio de placebo, realizando biopsia doble sextante, el dolor a varios intervalos después del procedimiento se registró en una escala visual análoga (EVA) de 0 a 10. Los 2 grupos fueron similares en cuanto a edad, volumen de próstata, antígeno prostático específico, diagnóstico histopatológico. Los pacientes que recibieron diclofenac tuvieron puntajes de dolor significativamente más bajos que los que recibieron placebo (2 frente a 3,35) p 0,02. La administración rectal de diclofenac antes de la realización de la biopsia de próstata es un procedimiento simple que alivia significativamente el dolor experimentado sin aumento en la morbilidad(AU)


The peri-prostatic nerve block with lidocaine, provides good pain relief in performing ultrasoundguided prostate biopsy, but the postprocedure pain can be significant, the addition of diclofenac suppository, could provide additional relief. Patients were randomly assigned in 2 groups to group 1 blockade with lidocaine of the prostatic peri plexus + suppository of diclofenac sodium and group 2 blockade with lidocaine of the prostatic peri plexus + placebo suppository, performing double sextant biopsy, pain at several intervals after the procedure was recorded on a visual analog scale (EVA) from 0 to 10. Thee 2 groups were similar in terms of age, prostate volume, prostate-specific antigen, histopathological diagnosis. Patients who received diclofenac had pain scores significantly lower than those who received placebo (2 vs. 3.35) p 0.02. Rectal administration of diclofenac before performing a prostate biopsy is a simple procedure that relieves significantly pain experienced without increased morbidity(AU)
