Estudio observacional sobre las técnicas de punción del bloqueo axilar para cirugía de mano en pacientes ambulantes en un hospital universitario: Aportes a la ecografía / No disponible

Objetivos: Valorar el aporte de la ecografía para la realización de bloqueos axilares en cirugía mayor ambulatoria con tres tipos de técnicas. Material y métodos: Estudio observacional, prospectivo en pacientes programados para cirugía de manos. Se construyó una base con datos demográficos, el tipo y eficacia de la técnica en cuanto al bloqueo motor y sensitivo, dolor posoperatorio, el grado de satisfacción y complicaciones asociadas. Las tres técnicas estudiadas fueron el uso de neuroestimulador, el uso de la ecografía y la combinación de ambas. Resultados: Se recogieron 151 casos. 77(51 %) se realizaron con NS solo, 36 (24 %) combinando la técnica de NS con Eco, y 38 (25 %) con Eco solo. 15 (20 %) pacientes puncionados con NS requerían un refuerzo de anestesia local versus 14 (38,9 %) en el grupo NS + Eco y 1 (2,6 %) en el grupo Eco solo (p < 0,001). La técnica combinada NS + Eco ha permitido bajar más el volumen de anestésico local comparado con la técnica Eco sola (NS + Eco: 26,2 ± 7,3; Eco solo: 31,4 ± 5,6; p = 0,001). En las 24 primeras horas posoperatorias, no hubo diferencias significativas en el consumo de analgésicos (p = 0,59). El índice de satisfacción era alto y comparable entre los tres grupos (NS: 8,4 ± 1,7/10; NS + Eco: 8,5 ± 1,9/10; Eco: 9,0 ± 1/10; p = 0,17). No hubo complicaciones ni reingresos a las 24 horas de la realización del bloqueo. Conclusión: La técnica ecográfica es segura y permite aumentar la seguridad del bloqueo con una eficacia equivalente o mejor a la técnica neuroestimulada. En cambio, la combinación de las 2 técnicas, da peores resultados, por lo que no recomendamos su uso (AU)

Objective: Asses the role of ultrasound guided axillary block in hand day case surgery with three different techniques. Materials and methods: we design a prospective, observational study in patients scheduled for day case hand surgery. Demographics data, type and efficiency of technique regarding sensitive and motor block, postoperative pain, satisfaction survey and complications were recorded. Block using neurostimulator (NS), ultrasound guide (US) and the combination of both was evaluated (NS+US). Results: 151 patients were included. 77 (51 %) were performed only by NS, 36 (24 %) using both techniques and 38 (25 %) with US solely. 15 (20 %) patients blocks by NS required an extra dose of local anesthetic in relation to 14 (38.9 %) in NS + US group and only 1 patient (2.6 %) block using US (p < 0.001). The combination technique allow to reduce total volume of local anesthetic used respect US guide block (NS + US: 26.2 ± 7.3; US: 31.4 ± 5.6; p = 0.001). In the first postoperative day, no different in analgesic consumption between three groups was found (p = 0.59).The satisfaction was high and comparable in all patients regardless of the technique used (NS: 8.4 ± 1.7/10; NS + US: 8.5 ± 1.9/10; US: 9.0 ± 1/10; p = 0.17). No complications and readmission was reported. Conclusion: US guided are a safe technique and make possible to increase block safety and efficiency. Nevertheless, the combination technique gives worse results and we should avoid their use (AU)

[General anaesthesia and obstetric bleeding in caesarean section. One year's experience in a university hospital]. / Anestesia general y hemorragia obstétrica con transfusión en la cesárea. Experiencia durante un año en un hospital universitario.

INTRODUCTION: Obstetric haemorrhage is an important worldwide cause of morbidity and mortality. General anaesthesia for caesarean section is rarely used. Our goal is to analyse the incidence, causes and risk factors associated with general anaesthesia for caesarean section, and the prevalence of obstetric haemorrhage (HO), its risk factors and predictors of post-caesarean HO together with the use of blood in our hospital population. METHODS: A retrospective study was conducted on all caesarean section discharge reports from PACU in 2008. RESULTS: General anaesthesia was required in 12.4% of the patients. Epidural catheter failure as a cause of general anaesthesia was infrequent (2.8%) and within the recommended standards. CONCLUSIONS: The most frequent indications for caesarean section under general anaesthesia included mainly life-threatening emergencies, and the most important risk factors for general anaesthesia, including coagulation disorders, bleeding in the third trimester, foetal distress and severe pre-eclampsia. General anaesthesia is a risk factor for transfusion, as is abruptio placentae, placenta previa and pre-eclampsia.

[Estimating the angle of left lateral decubitus position during cesarean section: observational study of anesthesiologists' estimates and of midwives and nurses' level of understanding]. / Estimación del decúbito lateral en cesáreas: estudio observacional entre anestesiólogos y conocimiento de matronas y personal de enfermería obstétrica.

OBJECTIVES: To determine the difference between the estimated and measured values of the left lateral decubitus (LLD) angle in the positioning of patients for scheduled cesarean section; to determine whether the accuracy of estimates differs between staff anesthesiologists and residents; and to assess the angle estimates of midwives and surgical nurses as well as their level of knowledge with respect to the utility of the LLD position. METHODS: This was a prospective, observational, double-blind study comparing staff anesthesiologists working in obstetrics to residents in their second, third, or fourth-year of training. We also presented a task and questions to midwives and surgical nurses who assisted during categories 3 and 4 cesarean sections (elective and scheduled procedures) according to the classification system of he National Institute of Clinical Excellence. The anesthesiologist was asked to place the patient in LLD position after onset of anesthesia and to estimate the LLD angle. A second anesthesiologist measured the angle. The midwives and nurses were asked to place a vacant surgical table at approximately 15 degrees; the angle was then measured. Patient variables (weight, height, anesthetic technique) and staff variables (position, understanding of the purpose of the maneuver, estimated DLL angle, and measured angle) were recorded. RESULTS: Of 55 women who underwent cesarean sections (98.18% under regional anesthesia), 25 were assessed by staff anesthesiologists and 30 by residents. A total of 14 midwives and 10 surgical nurses participated in the surgical table positioning task and answered questions. The mean (SD) DLL angle estimate of the anesthesiologists was 12.4 degrees (3.4 degrees); the mean measured angle was 7.8 degrees (3.1 degrees). The estimates of staff anesthesiologists were significantly more accurate (P < .001). All the midwives understood the reason for using the DLL position in cesarean section, while only 1 nurse (10%) did (P < .05). CONCLUSION: The DLL position angle is overestimated by resident anesthesiologists and midwives. It seems that the use and understanding of DLL positioning could be improved.

Ahorro de sangre en la artopalstia total de rodilla / No dsiponible

La hemorragia en el postoperatorio de artroplastia total de rodilla y la necesidad de transfusión son frecuentes. La transfusión de sangre homóloga (TSH) ha pasado a considerarse un procedimiento que conlleva mínimos riesgos proporcionando una mejor oxigenación a los tejidos. Sin embargo, la TSH puede ir acompañada de complicaciones como infecciones, reacciones de incompatibilidad, lesión pulmonar aguda, inmunodepresión, mayor tiempo de ingreso y un incremento de la mortalidad. El objetivo de este trabajo es revisar todas aquellas técnicas alternativas que tenemos a nuestro alcance para minimizar la hemorragia perioperatoria y optimizar la transfusión de forma individualizada en cada paciente en la cirugía protésica de rodilla(AU)

Postoperative bleeding in total knee arthroplasty and the need for transfusion are frequent. Homologous blood transfusion (TSH) is considered actually a procedure with minimal risks, providing a better tissue oxygenation. However, TSH may be accompanied by complications such as infections, incompatibility reactions, acute lung injury, immune suppression, increased length of hospital stay and increased mortality. Our goal is to review all the available techniques to minimize perioperative bleeding and transfusion optimization for each patient individually in knee prosthetic surgery(AU)
