Puesta al día sobre transfusión masiva / Massive transfusion update / Atualização sobre transfusão maciça

La transfusión masiva plantea desafíos clínicos, organizacionales y logísticos para el personal de la salud en general y los servicios de Medicina Transfusional en particular. No existe una definición universalmente aceptada de transfusión masiva, las definiciones más comúnmente utilizadas se basan en el número de unidades de sangre administradas dentro de un cierto período de tiempo. La mayoría de los eventos de transfusión masiva ocurren en el contexto de hemorragias graves en pacientes quirúrgicos, politraumatizados, con hemorragia gastrointestinal u obstétrica. La reanimación de control de daños y los protocolos de transfusión masiva son las estrategias más utilizadas actualmente para el tratamiento inicial, seguidas de un tratamiento personalizado, dirigido por objetivos, mediante la monitorización de la coagulación en tiempo real mediante estudios viscoelásticos. Existen una serie de controversias alrededor del tratamiento óptimo, incluyendo el uso de sangre total, la relación de hemocomponentes a utilizar, el uso de concentrados de factores de la coagulación, y la indicación óptima del ácido tranexámico. El estudio de los productos ideales para el tratamiento de los pacientes con sangrado masivo se ha convertido en un área de gran interés de la investigación científica. El contexto clínico en el que ocurrió el evento hemorrágico, el número de hemocomponentes transfundidos, la edad del paciente y las comorbilidades son los predictores más importantes de la sobrevida a corto y largo plazo. Esta revisión narrativa explora el estado actual del conocimiento sobre la transfusión masiva, así como los avances que podemos esperar en el futuro cercano.

Massive transfusion poses clinical, organizational and logistic challenges for the health staff in general, and the Transfusion Medicine Services in particular. There is no universally accepted definition for massive transfusion, the most widely used being based on the number of blood units administered in a certain period of time. Most massive transfusion events occur in the context of severe hemorrhage on surgical or multiple-trauma patients or patients with gastrointestinal or obstetric bleeding. Today, damage control resuscitation and massive transfusion protocols are the most common strategies for initial treatment, followed by personalized therapy, goal-directed, my means of monitoring coagulation in real time with viscoelastic studies. There are disputes as to the best surgical treatment, including using whole blood, the relation of blood components to be used, the use of coagulation factor concentrates and the optimal indication of tranexamic acid. The study of ideal products to treat patients with massive hemorrhage has become an area of great interest for scientific research. The clinical context of the hemorrhagic event, the number of blood components transfused, patient's age and comorbilities are the most important predictors for survival in the short and long term. This narrative review explores the current state of affairs on knowledge about massive transfusion, as well as progress to be expected in the near future.

Establishment of a risk model of placental accreta spectrum by ultrasound combined with clinical high risk factors / 中华超声影像学杂志

Objective:To establish a risk model of placenta accreta spectrum(PAS) based on the clinical risk factors and ultrasound signs of patients with placenta accreta, and identify severe placenta accreta prenatal.Methods:A retrospective analysis was performed on 121 PAS patients admitted to Beijing Obstetrics and Gynecology Hospital Affiliated to Capital Medical University from January 2018 to June 2022 who were clinically classified or pathologically diagnosed during delivery. The two groups were divided into light and severe groups according to the implantation type. The clinical risk factors and ultrasound signs between the two groups were compared. A risk model of PAS was established based on the clinical risk factors and ultrasound signs to predict the perinatal complications.Results:A total of 130 cases of PAS were clinically diagnosed or pathologically diagnosed with placenta, 9 cases with incomplete clinical data or irregular ultrasound images were excluded, and the remaining 121 cases were included in the study. Among the 121 patients, 64 cases were placental accreta, 39 cases were placental increta, and 18 cases were placenta percreta. The placental accreta was defined as mild group, and the combination of placental increta and placenta percreta were referred to as severe group. There were no significant differences in placenta previa, and the number of uterine cavity operations (all P>0.05). There were significant differences in the number of cesarean section, myometrium thinning, placental lacunae, abnormal vascularization at the utero-bladder junction, bridging vessels at the utero-bladder junction, placental protuberance and cervical involvement (all P<0.05). Binary logistic regression analysis showed that placental lacunae, abnormal vasculization of the utero-bladder interface and the number of cesarean sections were independent risk factors for severe PAS. Based on this, a risk model was established and the ROC curve of each independent risk factor and risk model was plotted respectively. The AUC of the risk model was 0.826, which had better diagnostic efficacy than other independent risk factors. Conclusions:In the prenatal ultrasound classification diagnosis of high-risk patients with PAS, the placental lacunae, abnormal vascularization of utero-bladder interface and the number of cesarean section are combined to establish the risk model of PAS, which has a good diagnostic efficacy for severe placenta accreta.

Objective:Analyze the influence of blood transfusion therapy under the guidance of thromboelastography on the blood potassium and coagulation indicators and prognosis of patients with post-traumatic hemorrhage.Methods:The clinical data of 73 patients with post-traumatic hemorrhage in Liyang People′s Hospital from March 2018 to February 2021 were retrospectively analyzed. Among them, TEG blood transfusion guidance group (group A) and conventional coagulation indicator guidance group (group B) were divided according to whether TEG test was performed. Repeated measurement analysis of variance and post LSD- t test were used to observe serum potassium, coagulation indexes and prognosis of 2 groups at each time point. Results:The amount of various drugs used in group A was significantly lower than that in group B ( P<0.05). Comparison of serum potassium levels between the two groups before transfusion: (3.94 ± 0.85) mmol/L vs. (3.98 ± 0.71) mmol/L; and on the first day after transfusion: (4.33 ± 0.48) mmol/L vs. (4.57 ± 0.73) mmol/L, there were statistically significant ( P<0.05); on day one. day two and day three after blood transfusion, the indexes of PT and APTT in group A were significantly lower than those in group B: PT: (14.30 ± 1.43) s vs. (16.25 ± 1.74) s, (14.41 ± 1.55) s vs. (16.27 ± 1.48) s, (14.73 ± 1.50) s vs. (16.30 ± 1.45) s; APTT: (32.3 ± 3.6) s vs. (36.7 ± 3.5) s, (32.6 ± 3.4) s vs. (36.8 ± 3.6) s, (32.2 ± 3.2) s vs. (36.3 ± 3.3) s; the above indexes of the two groups before treatment were significantly higher than those at each time point after treatment ( P<0.05). The total effective rate of hemostasis in group A was higher than that in group B: 97.37%(37/38) vs. 80.00%(28/35), P<0.05. Conclusions:Patients with post-traumatic hemorrhage can be recovered by blood transfusion under the guidance of thromboelastography, and the disorder of blood coagulation indicators can be restored, and at the same time, it has a better hemostatic effect.

Predictive value of ultrasound signs of the involvement of the cervix in the adverse pregnancy outcomes of placenta accreta spectrum / 中华超声影像学杂志

Objective:To explore the the predictive value of ultrasound signs of the involvement of the cervix in the clinical grade diagnosis of placenta accreta spectrum(PAS) with placenta previa and adverse pregnancy outcomes.Methods:A retrospective analysis was performed on PAS patients with placenta previa diagnosed during delivery or by cesarean section in Beijing Obstetrics and Gynecology Hospital Affiliated to Capital Medical University from January 2018 to March 2021. According to the signs of cervical involvement on prenatal ultrasound, the patients were divided into cervical involvement group and cervical non-involvement group. Logistic analysis was performed on clinical data between the two groups. The clinical data, hysterectomy rate, intraoperative blood loss and clinical diagnosis were compared between the two groups.Results:There were 1 455 patients with PAS diagnosed by clinical diagnosis or placental pathology, of which 170 were with placenta previa, 24 with incomplete clinical data or non-standard ultrasound images, and the remaining 146 patients were included. In the cervical involvement group, all of 6 cases had placenta percreta. Of the 140 cases in the unaffected cervical group, 89 cases (63.6%) had placental accreta, 48 cases (34.3%) had placental increta, and 3 cases (2.1%) had placenta percreta. There were no significant differences of the age and uterine operation history between the two groups. There was significant difference in the number of cesarean sections between the two groups ( P<0.05). There were significant differences in intraoperative blood loss, hysterectomy rate and placenta accreta grade diagnosis between the two groups(χ 2/ Z=4.203, 11.165, 95.248, all P<0.05). Conclusions:The ultrasonographic signs of cervical involvement have a good predictive value for the pregnancy outcome of PAS.

"Massive hemoptysis" and shock after fever and cough / 中国当代儿科杂志

A boy, aged 11 years, was admitted due to intermittent fever for 15 days, cough for 10 days, and "hemoptysis" for 7 days. The boy had fever and cough with left neck pain 15 days ago, and antibiotic treatment was effective. During the course of disease, the boy developed massive "hemoptysis" which caused shock. Fiberoptic bronchoscopy revealed a left pyriform sinus fistula with continuous bleeding. In combination with neck and vascular imaging examination results, the boy was diagnosed with internal jugular vein injury and thrombosis due to congenital pyriform sinus fistula infection and neck abscess. The boy was improved after treatment with temperature-controlled radiofrequency ablation for the closure of pyriform sinus fistula, and no recurrence was observed during the follow-up for one year and six months. No reports of massive hemorrhage and shock due to pyriform sinus fistula infection were found in the searched literature, and this article summarizes the clinical features, diagnosis, and treatment of this boy, so as to provide a reference for the early diagnosis of such disease and the prevention and treatment of its complications.

Study of thrombocytopenia in pregnancy: clinical presentation and outcome at tertiary care rural institute

Background: Platelet count below 1.5 lakh/cumm is called as thrombocytopenia. After anaemia it is the second most common haematological disorder in pregnancy. It affects nearly 6 to 15%; on an average 10% of all pregnancies. Gestational thrombocytopenia is a clinically benign thrombocytopenic disorder usually occurring in late pregnancy. It resolves spontaneously after delivery.Methods: It is a hospital based prospective observational study over a period of 1 year. All pregnant women who attended OPD at the department of obstetrics and gynecology, UPUMS, Saifai for antenatal checkup were included for the study and blood sample was withdrawn.Results: Out of 263 cases enrolled for study, 90 women were found to have thrombocytopenia, and 173 had normal platelet count. Thus, incidence of thrombocytopenia was 34%. Gestational thrombocytopenia accounted for majority of cases of thrombocytopenia in pregnancy (50%) followed by hypertensive disorders (22.4%). It was further followed by ITP (11.11%) and dengue (5.5%).Conclusions: Gestational thrombocytopenia is the most common cause of thrombocytopenia during pregnancy (50%), but other underlying causes must be considered as well. A thorough history and physical examination will rule out most causes.

Diagnostic Effects and Influence Factors of Emergency Colonoscopy in Patients with Acute Lower Gastrointestinal Massive Hemorrhage / 昆明医科大学学报

Objective To analyze the diagnostic effects and influence factors of emergency colonoscopy in patients with acute lower gastrointestinal massive hemorrhage. Methods 56 cases of patients with acute lower gastrointestinal massive hemorrhage treated in our hospital from May 2016 to May 2017 were selected and treated with emergency colonoscopy. The causes of acute lower gastrointestinal massive hemorrhage were analyzed and the emergency colonoscopy completion conditions in patients with different bowel preparation methods and different degrees of bleeding were compared. According to the results of emergency colonoscopy, the patients were divided into the successful test group and the failed test group, and the clinical data of the two groups were compared, and the influencing factors of the emergency colonoscopy were analyzed. Results The causes of acute lower gastrointestinal massive hemorrhage were colon cancer, colonic polyps,colon diverticulum and so on. There was no significant difference in the rebleeding or bleeding aggravation rate of different intestinal preparation methods (P＞0.05), and the detection rate of active bleeding in the severe hemorrhage group was higher than that in the mild hemorrhage group and the moderate hemorrhage group (P＜0.05) . In the emergency colonoscopy group, the number of patients in the successful test group, who were females, aged more than 45 years old, with a appendectomy history, a short walking time during the medication, an inadequate intestine preparation, unfinished lustramentum before examination, intestinal anatomical abnormalities and a non-standard physician operation,were lower than those in the failed test group (P＜0.05) . Logistic regression analysis showed that being female, aged over 45, inadequate bowel preparation and intestinal anatomical abnormalities were the independent risk factors for emergency colonoscopy failure in patients with acute lower gastrointestinal massive hemorrhage (P＜0.05) .Conclusions Emergency colonoscopy has important diagnostic significance for acute lower gastrointestinal massive hemorrhage especially the moderate to severe hemorrhage. Female, aged more than 45 years old, inadequate intestinal preparation and intestinal anatomical abnormalities are the independent influencing risk factor for diagnostic effects.

Analysis of Application of Massive Transfusion Protocol for Trauma Patients at a Single Tertiary Referral Hospital / 대한수혈학회지

BACKGROUND: Massive hemorrhage due to trauma is one of the major causes of death in trauma patients, and the quick supply of appropriate blood products is critical in order to reduce the mortality rate. We introduced a massive transfusion protocol (MTP) for safe and rapid transfusion of trauma patients. Using records collected since its adoption, we compared the characteristics of MTP applied group (MTP group) and MTP not applied group (non-MTP group) to determine whether there is an indicator for predicting patients to be treated with MTP. METHODS: We retrospectively reviewed the electronic medical records and laboratory findings of patients who received massive transfusions in the trauma emergency room of a single tertiary hospital from February to August 2018. We analyzed various laboratory test results, the amount and ratio of the transfused blood products, and the time required for blood products to be released for the MTP group and the non-MTP group. RESULTS: Of the 54 trauma patients who received massive transfusions, 31 were in the MTP group and 22 in the non-MTP group. There was no significant difference in initial vital signs (except blood pressure) and laboratory test results. Also there was no difference in the amount and ratio of blood products, but the time required for blood product release was shorter in the MTP group. CONCLUSION: There was no significant difference in clinical findings such as initial vital signs and laboratory test results between the MTP and non-MTP groups, but required blood products were prepared and released more quickly for the MTP group.

Development and application of disposable constant volume and negative pressure drainage device / 中华危重病急救医学

The common negative pressure drainage bottle used in the vacuum sealing drainage (VSD) cannot quantitative and automatically cut off. Excessive drainage damages the negative pressure source, causes drainage interruption, so once drainage was continuously performed, medical staff need to closely observe drainage bottle calibration. It was also important to known whether there was a large amount of fresh blood sucked out during continuous drainage because it could lose too much blood. To solve these two problems, we designed a kind of negative pressure drainage device, which volume was constant, with the function of automatic cutting off continuous drainage. It can not only prevent drainage fluid flowing back to the negative pressure source and cause drainage interruption, but also prevent massive blood loss from continued drainage after the hemorrhage. We could benefit from this device, which possess many advantages, such as simple structure, security and reliability. It is worthy promoting in the clinical work.

Coagulopatía Aguda Traumática y hemorragia masiva: una relación que debemos conocer / Acute traumatic coagulopathy and massive hemorrhage: a relationship that we should know

Los traumatismos y accidentes ocupan una proporción relevante de las causas de muerte para el grupo de edad que abarca desde la primera infancia hasta la cuarta década de la vida. En los últimos diez años la mortalidad mundial por traumatismos se incrementó en el 20 por ciento. En esos casos se estima que las hemorragias aportan entre el 30 y 70 por ciento de la mortalidad. Además, la hemorragia masiva es conocida por ser una de las principales causas de muerte intraoperatoria en pacientes sin traumatismos, sobre todo en aquellos sometidos a intervenciones que implican lesiones tisulares importantes. En alrededor de un tercio o más de esos pacientes se desarrolla una coagulopatía aguda asociada al trauma o coagulopatía aguda traumática, que obedece a mecanismos fisiopatogénicos complejos, superpuestos y dependientes en gran medida de la naturaleza del evento que originó la pérdida sanguínea. Esta coagulopatía se define básicamente como una reducción funcional de la fortaleza del coágulo con cambios mínimos en los tiempos de coagulación. Su aparición incrementa el riesgo de sangrado masivo, la utilización de mayores volúmenes de componentes sanguíneos e implica una mayor probabilidad de fallecer por hemorragia. Su identificación temprana mediante técnicas de evaluación hemostáticas como el TP/INR, y pruebas viscoelásticas (tromboelastometría rotacional y tromboelastografía), modifica los riesgos y aporta un blanco terapéutico factible que constituye la base de las nuevas estrategias transfusionales en el enfrentamiento a los sangrados masivos(AU)

Accidents and different kind of injuries account for a relevant proportion of death causes from childhood to the fourth decade of life. Death from injury has increased by 20 percent over the last decade. Hemorrhages are estimated to cause between 30 to 70 percent of those deaths. Massive bleeding is also known for being one of the main causes of death during surgery in cases with extensive tissue damage from not traumatic origin. In around one third or more of such patients an acute traumatic coagulopathy or trauma associated coagulopathy is developed. This phenomenon obeys to complex, overlapping mechanisms which would be in its major part dependent on the event that caused the blood lost. This kind of coagulopathy can be defined as a functional reduction in clot strength with only minimal changes in clotting times. Its presence increases the risk of a massive bleeding, the use of larger volumes of blood components and the likelihood of dying by the hemorrhage. The early identification of acute traumatic coagulopathy through hemostatic tests such as TP/INR and viscoelastic assays as thrombelastography or rotational thrombelastometry modifies those risks since it brings a feasible therapeutic target to aim at, becoming the cornerstone for the newer transfusional strategies while facing massive bleedings(AU)

Damage control resuscitation of massive hemorrhage: The key to saving the combat casualties / 解放军医学杂志

Combat casualties can be divided into two types,i.e.,non-survivable (NS) and potentially survivable (PS).According to the data of US army,massive hemorrhage constituted 90.98％ of the potentially survivable casualties,and the most important thing to improve the ability of casualty care is hemorrhage control.In this article,the strategies and techniques of damage control resuscitation like surgical hemorrhage control techniques of non-compressive hemorrhage (NCH) in torso and junctional area,the damage control identification of the injured,field transfusion process and fresh whole blood infusion in tactical level and emergency phase were comprehensively illustrated.

Aberrant right subclavian artery-esophageal fistula: massive upper gastrointestinal hemorrhage secondary to prolonged intubation / Fístula de artéria subclávia direita anômala com esôfago - hemorragia digestiva alta maciça secundária a intubação gástrica prolongada

ABSTRACT Aberrant right subclavian artery-esophageal fistula is a rare but potentially fatal complication. It may be associated with procedures, such as tracheostomy and tracheal or esophageal intubation, and yields massive upper gastrointestinal bleeding difficult to identify and to control. A high index of suspicion is essential for early diagnosis and better prognosis. We report a rare case of a patient who survived after emergent surgical procedure for massive upper gastrointestinal bleeding secondary to aberrant right subclavian artery-esophageal fistula after prolonged intubation.

RESUMO A fístula de artéria subclávia direita anômala com o esôfago é uma complicação rara, mas potencialmente fatal. Pode estar associada a procedimentos como traqueostomia e intubação traqueal ou esofágica e originar hemorragia digestiva alta maciça, de difícil identificação e controle. Um elevado índice de suspeição é essencial para o diagnóstico precoce e a melhoria do prognóstico. Relatamos caso raro de doente que sobreviveu após intervenção cirúrgica emergente por hemorragia digestiva alta maciça secundária a fístula de artéria subclávia direita anômala com esôfago, após intubação gástrica prolongada.

Analysis of Massive Transfusion for Trauma Patients and Non-Trauma Patients in a Tertiary Hospital / 대한수혈학회지

BACKGROUND: Management of patients with massive hemorrhage often requires the massive blood transfusions. However, few studies have investigated the effects of massive transfusions on non-traumatic patients. Therefore, this study analyzed mortality and descriptive data for patients receiving massive transfusion, including non-trauma patients and trauma patients. METHODS: We reviewed a retrospective audit of massive transfusions to investigate the major causes, patient characteristics, ratio of the blood components, and the mortality of massively transfused patients. The analysis was performed using electronic medical records collected from January 2010 to December 2013. Patients who had received a massive transfusion (≥10 units of RBCs within 24-hours) were categorized into trauma and non-trauma patients. We calculated the ratio of blood components and investigated the relationship between ratio and mortality. Descriptive statistics were used to characterize the patients and the indications. RESULTS: A total of 532 massive transfusions were performed, including 187 trauma and 345 non-trauma patients. The overall mortality rate was 32.0%, encompassing 36.4% of the trauma patients and 29.6% of the non-trauma patients. The mortality in trauma patients was significantly reduced (P<0.001) within the first 48-hours compared with that in non-trauma patients, which was due to the high FFP: RBC ratio transfusion. The annual FFP: RBC ratio in trauma patients showed an increasing trend. Non-trauma patients showed no relationship between mortality and procedure indication/blood component ratio. CONCLUSION: We report clinical data pertaining to massive transfusions. Annual increasing FFP: RBC ratio in trauma patients was associated with a decreasing mortality. Non-trauma patients showed heterogeneous characteristics and a lower FFP: RBC ratio than trauma patients.

Anesthetic review of emergency peripartum hysterectomy following vaginal and cesarean delivery: a retrospective study / 대한마취과학회지

BACKGROUND: The purpose of this study was to review incidence, indications, complications, and the anesthetic management of emergency obstetric hysterectomies. METHODS: This was a retrospective study of the cases of emergency obstetric hysterectomies performed at the Woman's Hospital over a 3 year period between January 2008 and December 2010. The indication for surgery, anesthetic management, operating time, estimated blood loss, pre- and postoperative hemoglobin and hematocrit values, need for blood transfusion, and perioperative complications were obtained. RESULTS: During the study period there were 46 emergency obstetric hysterectomies for 20147 deliveries, giving an incidence of 2.28/1000 deliveries. The number of emergency hysterectomies was significantly higher with the cesarean deliveries than with the vaginal deliveries. The most common indication for emergency obstetric hysterectomy was placenta accreta. Postoperatively, Dissemimated Intravascular Coagulation (DIC) was the most common complication. CONCLUSIONS: Abnormal placenta has been an main indication of emergency hysterectomy. Anesthesiologists should be eligible to aware of high risk of emergency hysterectomy and deal with massive hemorrhage.

Increased intracranial pressure after massive blood loss: A case report

A 4-year old boy with supravalvular ascending aortic stenosis underwent sliding aortoplasty. After cardiopulmonary bypass weaning, aorta suture site was torn accidentally and the patient was in hypovolemic shock. Emergency cardiopulmonary bypass was reinstituted and the aorta was repaired. After removal of the aortic clamp, bradycardia and hypertension were noted. We suspected increased intracranial pressure due to hypoxic brain damage after massive blood loss and the patient was treated to lower the intracranial pressure. Physicians should be aware of the significance of the hemodynamic change associated with increased intracranial pressure to prevent further neurologic damage.

A Case of Delayed Massive Hemorrhage after Endoscopic Resecting a Rectal Carcinoid Tumor / 대한소화기내시경학회지

Endoscopic resection is currently accepted as a standard therapy for colon polyp because of its safety and efficiency. The indications for endoscopic resection have been expanded to treat mucosal colon cancer and submucosal tumor. The major complications of endoscopic resection are hemorrhage, perforation and post- polypectomy coagulation syndrome. Hemorrhage is the most common complication, and this can occur immediately following colonoscopic polypectomy or it can be delayed after completion of the procedure. Delayed hemorrhage usually occurs within 7 days and this can stop by itself or the hemorrhage can be controlled endoscopically in the majority of patients, with only the unusual and serious cases requiring transfusion, angiography and surgery. We experienced a case of delayed massive hemorrhage with hypotension that required transfusion 12 days after performing endoscopic resection for rectal carcinoid tumor. We report here on this case to provide a good example and to place emphasis on delayed massive hemorrhage after endoscopic resection.
