RESUMO
Introducción: La anestesia para el angiofibroma juvenil es una de las intervenciones más complejas dentro de la otorrinolaringología, pues el sangramiento incoercible causa hipovolemia aguda la cual se produce en un breve período y lleva al shock hipovolémico y a la muerte de no tratarse adecuadamente. Objetivo: Realizar una actualización sobre el perioperatorio de la anestesia en el angiofibroma juvenil. Desarrollo: Se debe minimizar las pérdidas sanguíneas a toda costa. La mejor asociación fue la hipotensión inducida, la hemodilución hipovolémica y el predepósito de sangre autóloga, con la angiografia y embolización arterial selectiva del tumor. Conclusiones: La exéresis quirúrgica del angiofibroma juvenil es una intervención de alto riesgo. El equipo de trabajo constituye un elemento primordial. La asociación de hipotensión inducida, hemodilución hipovolémica y predepósito de sangre autóloga son los pilares fundamentales para la mejor evolución de estos pacientes(AU)
Introduction: Anesthesia for juvenile angiofibroma is one of the most complex interventions within otolaryngology, since incoercible bleeding causes acute hypovolemia, which occurs in a short period and leads to hypovolemic shock and death if not treated properly. Objective: To carry out an update about the perioperative period of anesthesia in juvenile angiofibroma. Development: Blood losses must be minimized at all costs. The best association was induced hypotension, hypovolemic hemodilution, and autologous blood predeposit, with angiography and selective arterial embolization of the tumor. Conclusions: Surgical removal of juvenile angiofibroma is a high-risk intervention. The work team is an essential element. The association of induced hypotension, hypovolemic hemodilution, and autologous blood predeposit are the fundamental pillars for the best evolution of these patients(AU)

Objective To explore the blood-saving and conservation effect and clinical prognosis of extracorporeal circulation circuits designed individually by using medical polymeric materials for adults and infants in cardiac surgical procedures.Methods A total of 41 new extracorporeal circulation circuits designed based on the operation requirements,including 20 for adults and 21 for infants,were applied on adults and infants (body weight less than 10 kg),and the results were compared with that of the conventional circuits on adults (20) and infants (19)respectively.Total priming volume,priming and intraoperative blood products consumption,pump pressure,intraoperative blood hemoglobin (Hb) level,free Hb (f-Hb),platelet (Plt) count,mixed venous oxygen saturation (SvO2),colloid osmotic pressure (COP),lactate (Lac) level,Hb level after modified ultrafiltration,endotracheal intubation time and ICU time were all collected in two groups.Results Priming volume,priming and intraoperative blood consumption and f-Hb level in the blood-saving and conservation circuits group were significantly lower than that of conventional circuits group (P＜0.05).There were no significant differences (P＞0.05) between the two groups in pump pressure,intraoperative blood Hb level,Plt,SvO2,COP,Lac level,Hb level after modified ultrafiltration,endotracheal intubation time and ICU time.Conclusions The minimized blood conservation extracorporeal circulation circuit plays an important role in reducing priming volume and blood transfusion.It maintains a normal level of hemodynamics,oxygenation and tissue perfusion level during cardiopulmonary bypass in cardiac surgery for adults and infants.Red blood cell destruction can be reduced by improving blood compatibility,and physical data are all stabilized intra and post operation.This new circuit is secure,with its better outcome,expected in application.
RESUMO
Objective: To explore the blood-saving effect of autologous platelet-rich plasma (PRP) back-transfusion in patients with Stanford type A aortic dissection surgery. Methods: A total of 59 consecutive patients who received Stanford type A aortic dissection surgery in our hospital from 2013-01 to 2015-10 were studied. The patients were at the age of (50±6) years with mean body weighting at (80±12) kg and were randomly divided into 2 groups: Traditional (T) group,n=31 and Autologous PRP back-transfusion (P) group,n=28. Blood levels of Hb, platelet counts, PT, APTT were measured at pre-induction of anesthesia (T1), before CPB (T2), prior ifnishing of CPB (T3) and at 1 h (T4), 24 h (T5), 48 h (T6) after the operation. The in-operative, 48 h post-operative volumes of allogeneic blood transfusion and the volume of chest tube drainage at 48h after operation were recorded; the complication occurrence at peri-operative period was recorded. Results: In P group, whole blood processing volume was (1269±197) ml, PRP volume was (753±78) ml, PRP separation time was (35±9) min and the separated platelets were about (22±3)% of total platelet counts. Compared with T group, P group had decreased Hb at T2 (131.0±15.0) g/L vs (101.0±10.0) g/L, decreased platelet counts at T3 (115.0±51.0)×109 /L vs (83.0±23.0)×109/L, while increased platelet counts at T4 (103.0±25.0)×109/L vs (151.0±27.0)×109/L, T5 (105.0±25.0)×109 /L vs (147.0±39.0)×109/L and T6 (101.0±26.0) ×109/L vs (149.0±35.0)×109/L, allP<0.05; P group presented reduced PT at T4 (17.6±2.1) s vs (14.1±1.1) s and T5 (17.6±2.7) s vs (13.5±0.8) s, allP<0.05. The in-operative transfusions of platelet, plasma, cold precipitation and post-operative transfusions of red blood cells, platelets, plasma, cold precipitation and the volume of chest tube drainage at 48h after operation were less in P group,P<0.05. Compared with T group, P group had the lower rates of acute post-operative lung injury (32.1% vs 19.4%), shorter mechanical ventilation time (69.1±5.9) h vs (43.1±1.5) h and ICU staying time (8.1±2.8) d vs (5.3±1.1) d, allP<0.05. Conclusion: Autologous PRP back-transfusion could reduce the post-operative bleeding and allogeneic blood transfusion for Stanford A aortic dissection surgery, it has obvious blood-saving effect.
RESUMO
PURPOSE: To compare the extramedullary femoral alignment guide system with the conventional intramedullary alignment guide system for bleeding and transfusion rate after total knee arthroplasty (TKA). MATERIALS AND METHODS: Forty-nine female TKA patients were randomized into two groups: intramedullary (IM) group vs. extramedullary (EM) group. Drained volume of blood, hemoglobin concentration, hemoglobin drop, and transfusion rate were compared between the two groups. Wound problems, bleeding-related problems and thromboembolic complications were collected. RESULTS: The mean drained volume via vacuum drainage was less in the EM group than that in the IM group (482.9 mL vs. 266.8 mL, p=0.001). Hemoglobin at 5 days after surgery was higher in the EM group (9.3 g/dL vs. 9.9 g/dL, p=0.002) than that in the IM group. The drop in hemoglobin after 5 days was smaller in the EM group (3.5 g/dL vs. 2.9 g/dL, p=0.003) than that in the IM group. The EM group had a lower prevalence of allogeneic transfusion (45.0% vs. 20.5%, p=0.026) than that in the IM group. No significant complications developed in either group. CONCLUSIONS: The results suggest that the extramedullary femoral alignment guide technique is an advantageous method that can reduce the drained volume of blood and the allogeneic transfusion rate.
