OBJECTIVE: To investigate the effect of intraoperative blood salvage autotransfusion on local recurrence and long-term metastasis of patients after carotid body tumor resection. METHODS: We retrospectively reviewed a consecutive series of 61 patients undergoing elective carotid body tumor resection from August 2009 to December 2020. Among them, 14 received intraoperative blood salvage autotransfusion (autotrasfusion group) and 47 did not (non-autotransfusion). Data of general information, surgical status and postoperative follow-up results were collected. RESULTS: The proportion of Shamblin Ⅲ in the autotransfusion group was 85.7%, which was significantly higher than 31.9% in the non-autotransfusion group (P=0.003). The average operation time of the 14 patients in the autotransfusion group was (264±84) min, intraoperative blood loss was 1 200 (700, 2 700) mL, and autologous blood transfusion was 500 (250, 700) mL. Of these, 8 patients (57%) required concomitant allogeneic blood with 400 (260, 400) mL of allogeneic blood. The average operation time of the 47 patients in the non-autotransfusion group was (153±75) min, and the intraoperative blood loss was 300 (100, 400) mL. Of these, 6 (13%) required allogeneic blood transfusion, and 520 (400, 520) mL of allogeneic blood was used. Compared with the non-autotransfusion group, the average operation time in the autologous blood transfusion group was significantly longer (P < 0.001), and the intraoperative blood transfusion volume was larger (P=0.007). Of the 14 patients undergoing autotransfusion, 8 (57%) needed allogeneic blood at the same time; while in the 47 non-autologous transfusion patients, 6 (13%) needed allogeneic blood transfusion. The proportion of autotransfusion group using allogeneic blood at the same time was even higher (P=0.002). The incidence of nerve injury within 30 days after surgery was 29.5%, and there was no significant difference between the two groups. No early deaths occurred. The average follow-up was (76±37) months. One case of local recurrence occurred in the non-autotransfusion group. There was no distant metastasis. There were no tumor-related deaths. The estimated 5-year and 10-year overall survival rates were 96.4% and 83.8%, respectively. There was no significant difference in overall survival between the two groups (P=0.506). CONCLUSION The use of intraoperative blood salvage autotransfusion increased no risk of local recurrence and distant metastasis in patients with carotid body tumor, which is safe and effective in carotid body tumor resection.

OBJECTIVE: To investigate the efficacy and safety of autologous blood transfusion during weaning from venous-arterial extracorporeal membrane oxygenation (VA-ECMO) under controlled rotational speed. METHODS: A retrospective study was conducted, selecting patients who underwent extracorporeal membrane oxygenation (ECMO) and successfully weaned at the emergency and critical care medicine center of Henan Provincial Third People's Hospital from January 2023 to May 2024. General data including gender, age, body mass index (BMI), European system for cardiac operative risk evaluation (EuroScore), and disease types were collected. Vital signs at weaning [heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and peripheral oxygen saturation], parameters before and after weaning [B-type natriuretic peptide (BNP), hemoglobin (Hb), partial pressure of arterial oxygen (PaO₂), partial pressure of arterial carbon dioxide (PaCO₂), arterial lactate, central venous pressure (CVP), inferior vena cava collapsibility index, left ventricular ejection fraction (LVEF), and right heart load], post-weaning inflammatory markers at 1-day and 3-day [body temperature, white blood cell count (WBC), neutrophil percentage (NEU%), C-reactive protein (CRP), procalcitonin (PCT), interleukin-10 (IL-10)], as well as complications (infection, thrombosis, renal failure, gastrointestinal bleeding) and post-weaning blood return status were recorded. Patients were divided into an observation group (with post-weaning blood return) and a control group (without post-weaning blood return) based on the presence of blood return after weaning. The changes in the aforementioned parameters were compared between the two groups. RESULTS: A total of 62 patients were included, with 31 cases in each group. No statistically significant differences were observed between the two groups in baseline characteristics including gender, age, BMI, and EuroScore. At weaning, the observation group exhibited relatively stable vital signs, with no significant differences in heart rate, SBP, DBP, or peripheral oxygen saturation compared to the control group. After weaning, the observation group showed significantly lower levels of BNP, PaCO₂, arterial lactate, CVP, and right heart load compared to pre-weaning values [BNP (ng/L): 2 325.96±78.51 vs. 4 878.48±185.47, PaCO₂ (mmHg, 1 mmHg≈0.133 kPa): 35.23±3.25 vs. 40.75±4.41, arterial lactate (mmol/L): 2.43±0.61 vs. 6.19±1.31, CVP (cmH₂O, 1 cmH₂O≈0.098 kPa): 8.32±0.97 vs. 15.34±1.74, right heart load: 13.24±0.97 vs. 15.69±1.31, all P < 0.05], while Hb, PaO₂, inferior vena cava collapsibility index, and LVEF were significantly higher than pre-weaning values [Hb (g/L): 104.42±9.78 vs. 96.74±6.39, PaO₂ (mmHg): 94.12±7.78 vs. 75.51±4.39, inferior vena cava collapsibility (%): 28±7 vs. 17±3, LVEF (%): 62.41±6.49 vs. 45.30±4.51, all P < 0.05]. No statistically significant differences were found between the observation group and control group in these parameters. At 3 days post-weaning, the observation group demonstrated significantly lower levels of body temperature, WBC, NEU%, CRP, PCT, and IL-10 compared to 1 day post-weaning [body temperature (centigrade): 36.83±1.15 vs. 37.94±1.41, WBC (×10⁹/L): 7.82±0.96 vs. 14.34±2.15, NEU%: 0.71±0.05 vs. 0.80±0.07; CRP (mg/L): 4.34±0.78 vs. 8.94±1.21, PCT (μg/L): 0.11±0.02 vs. 0.26±0.05, IL-10 (ng/L): 8.93±1.52 vs. 13.51±2.17, all P < 0.05], with no significant differences compared to the control group. No statistically significant differences were observed between the two groups in the incidence of complications including infection, thrombosis, renal failure, and gastrointestinal bleeding. CONCLUSION Autologous blood reinfusion during VA-ECMO weaning under controlled rotational speed is safe and effective, without increasing risks of infection or thrombosis.

From January 2013 to January 2015, 19 patients of traumatic hemothorax with hemorrhagic shock were treated in our department by thoracoscopic surgery combined with autologous blood transfusion. This study retrospectively analyzed the therapeutic effect and shared our experience. The average amount of blood transfused back was 662.41 ml ± 269.15 ml. None of the patients developed transfusion reaction and were all discharged uneventfully. Thoracoscopic surgery combined with autologous blood trans- fusion is effective in the rescue of patients with progressive hemothorax and hemorrhagic shock. When corresponding indications are well managed, treatment for these patients is quicker, safer, and more effective.

OBJECTIVETo evaluate whether intraoperative autologous donation (IAD) can reduce perioperative blood transfusion for patients underwent mitral valve replacement (MVR).

METHODSA total of 318 patients received implementation of IAD from January 2011 to December 2013 were analyzed retrospectively, and compared with 517 patients of the previous 36-month period (from January 2008 to December 2012). The method of small-volume retrograde autologous priming, strict blood transfusion standard along with IAD together constituted a progressive blood-saving strategy. Statistical methods including Students' t-test, Pearson's χ(2) test, Kruskal-Wallis analysis and multivariate Logistic regression model were used for comparisons of the data.

RESULTSThere were no significant difference between IAD group and non-IAD group considering preoperative patient demographics, characteristics and preoperative comorbidities. However, IAD group significantly reduced number of patients transfused with intra/post-operative packed red-blood cell (PRBC) (55(17.0%) vs. 215 (42.1%), χ(2)=53.0, P=0.000), and had significantly reduced postoperative chest tube output (150(380) ml vs. 700(660) ml, H=195.648, P=0.000), length of stay ((16±6) d vs. (20±8)d, t=9.60, P=0.000). But hematocrit were lower in IAD group (30%±5% vs.33%±4% at end of operation, t=7.76, P=0.000; 30%±4% vs. 32%±5% at discharge, P=0.000, t=3.86). Multivariate logistic aggression analysis revealed that age, IAD and smoking history were factors influencing the probability of intra or postoperative blood transfusion.

CONCLUSIONImplementation of blood conservation strategies based on intraoperative autologous donation in mitral valve replacement surgery can significantly reduce intra/postoperative blood transfusion as well as postoperative complications.

INTRODUCTIONIntraoperative cell salvage (ICS) is an important aspect of patient blood management programmes. An ICS service was introduced at KK Women's and Children's Hospital, Singapore, from 2 May 2011 to 30 April 2013 to aid in the management of massive obstetric haemorrhage.

METHODSWith support from the Ministry of Health's Healthcare Quality Improvement and Innovation Fund, a workgroup comprising obstetricians, anaesthetists and nursing staff was formed to develop training requirements, clinical guidelines and protocols for implementing ICS using the Haemonetics Cell Saver 5. Pregnant women with an anticipated blood loss of > 1,000 mL during Caesarean delivery, a baseline haemoglobin level of < 10 g/dL, rare blood types and who had refused donor blood were recruited to the service after obtaining informed consent.

RESULTSA total of 11 women were recruited to the ICS service; the primary indications were placenta praevia and placenta accreta. Median blood loss in these 11 patients was 1,500 (range 400-3,000) mL. In four patients, adequate autologous blood was collected to initiate processing and salvaged, processed blood was successfully reinfused (mean 381.3 [range 223.0-700.0] mL). Median blood loss among these four patients was 2,000 (range 2,000-3,000) mL. No adverse event occurred following autologous transfusion. Mean immediate postoperative haemoglobin level was 8.0 (range 7.1-9.4) g/dL.

CONCLUSIONThe implementation of an obstetric ICS service in our institution was successful. Future studies should seek to address the cost-effectiveness of ICS in reducing allogeneic blood utilisation.

OBJECTIVETo study the effect of autologous drained blood reinfusion on hidden blood loss and limb swelling following rivaroxaban anticoagulation for primary total hip arthroplasty.

METHODSFrom May, 2011 to October, 2012, 98 patients undergoing primary unilateral total hip arthroplasty received rivaroxaban therapy for prevention of deep venous thrombosis (DVT). Forty-five of the patients used a drained blood reinfusion device (group A) and 53 patients did not (group B). Hidden blood loss and the maximal changes of postoperative circumferential length of the mid-thigh were measured and compared between the two groups.

RESULTSThe mean total blood loss, the hidden blood loss, and the maximal changes of postoperative thigh circumference were 1591.1∓337.3 ml, 1591.1∓337.3 ml, and 5.1∓2.8 cm in group A, as compared to 1374.5∓317.3 ml, 467∓96.8 ml, 3.9∓1.4 cm in group B, respectively. The two groups showed a significant difference in the maximal changes of postoperative mid-thigh circumference (P<0.01) but not in hidden blood loss (P>0.05).

CONCLUSIONReinfusion of autologous drained blood does not affect hidden blood loss but can increase limb swelling following primary total hip arthroplasty with rivaroxaban anticoagulation.

Here, we report a large, overhanging cystic bleb that compromised vision and induced a foreign body sensation in a patient who underwent a trabeculectomy surgery with anti-metabolite therapy 4 years prior. Ultrasound biomicroscopy revealed multiple loculations with thin septa inside the bleb and a high risk of damage to the bleb was anticipated with a straight forward surgical excision. We injected autologous blood and placed a compression suture 6 weeks prior to surgical excision of the overhanging portion of the bleb. The operation was successful in preserving excellent bleb function, restoring visual acuity, and alleviating symptoms in our patient with up to 9 months of follow-up.

OBJECTIVETo explore the feasibility of intraoperative autologous transfusion in modified total hepatic vascular exclusion under normal temperature for extracapsular resection of giant hepatic hemangioma.

METHODSThe clinical data of 32 patients undergoing hepatic resection with total hepatic vascular exclusion requiring intraoperative autologous transfusion were analyzed retrospectively. The tumors in these cases involved the proximal hepatic veins and inferior vena cava, with hemangioma volume ranging from 12 cm x 15 cm to 18 cm x 40 cm.

RESULTSThe hemangioma were completely resected in all patients, who all recovered smoothly. In one case, hemangioma rupture occurred during dissociation of the liver, resulting in massive hemorrhage which required blood transfusion of 6000 ml. Four patients received blood transfusion of 400-800 ml, and the other 27 had no blood transfusion. Only 8 patients underwent pringle maneuver with resection, whereas the other 27 underwent total hepatic vascular exclusion during liver resection for 5-30 min (mean 16 min).

CONCLUSIONIntraoperative autologous transfusion in modified total hepatic vascular exclusion under normal temperature is feasible and safe for extracapsular resection of huge hepatic hemangioma adjacent to the major arteries.
