African health sciences. 2023;23(3):514-520
Abstract
BACKGROUND To probe into the influences of different blood conservation techniques on the postoperative coagulation function and prognosis of elderly patients receiving Total Hip Arthroplasty (THA). METHODOLOGY A total of 60 patients were randomly divided into Autologous Blood Transfusion (ABT) group (n=30) and ANH group (n=30). For patients in the ABT group, an autologous blood recovery machine was used to recover, wash and filter the surgical field blood. For those in the Acute Isovolumic Hemodilution (ANH) group, blood was collected preoperatively from the central vein and stored in a citrate anticoagulant blood storage bag, while the same amount of hydroxyethyl starch was injected into the peripheral vein to dilute the blood. After Mai bleeding steps of the operation were completed, the autologous blood of patients was transfused back in both groups. The clinical indicators of patients in each group were observed. RESULTS 48 h after operation, the ANH group obtained a higher level of hemoglobin (Hb), shorter Activated Partial Thromboplastin Time (APTT), and a lower expression rate of platelet activating factor CD62P than the ABT group. CONCLUSION The ANH group exhibits higher content of hemoglobin and fewer platelet (Plt)activating factors produced than the ABT group, while no significant difference in the shortened length of hospital stays is found.

Abstract
OBJECTIVE To explore the effect of acute normovolemic hemodilution (ANH) on the anesthetic effect, plasma concentration, and postoperative recovery quality in elderly patients undergoing spinal surgery. METHODS A total of 60 cases of elderly patients aged 65 to 75 years who underwent elective multilevel spinal surgery were assigned randomly into the ANH group (n = 30) and control group (n = 30). Hemodynamic and blood gas analysis indexes were observed and recorded before ANH (T(1)), after ANH (T(2)), immediately after postoperative autologous blood transfusion (T(3)), 10 min (T(4)), 20 min (T(5)), 30 min (T(6)), 40 min (T(7)), and 50 min (T(8)) after the transfusion, and at the end of the transfusion (i.e., 60 min; T(9)). At T(3 ~ 9), bispectral index (BIS) and train-of-four (TOF) stimulation were recorded and the plasma propofol/cisatracurium concentration was determined. The extubation time and recovery quality were recorded. RESULTS The ANH group presented a lower MAP value and a higher SVV value at T(2), and shorter extubation and orientation recovery time (P < 0.05) compared with the control group. BIS values at T(8) and T(9) were lower in the ANH group than those in the control group (P < 0.05). TOF values at T(7 ~ 9) were lower in the ANH group than those in the control group (P < 0.05). There were no statistically significant differences in the postoperative plasma concentrations of propofol and cisatracurium between the groups (P > 0.05). CONCLUSION During orthopedic surgery, the plasma concentration of elderly patients is increased after autologous blood transfusion of ANH, and the depth of anesthesia and muscle relaxant effect are strengthened, thus leading to delayed recovery of respiratory function and extubation.

Wu, Y., He, J., Han, X., Xu, Q., Dai, H., Wu, J.
The Journal of international medical research. 2023;51(11):3000605231206963
Abstract
OBJECTIVE This study was performed to evaluate the effect of a homemade autotransfusion pressure-control system on the regulation of negative pressure and to clarify the influence of different negative pressures on the recovered erythrocytes. METHODS Fifty patients were randomly divided into five groups, and five different suction-generated negative pressures were applied. Before suction, 6 mL of blood was collected from the surgical field; after suction, 6 mL of blood was collected from the blood storage tank. The hemoglobin, hematocrit, mean corpuscular volume, newly generated standardized plasma free hemoglobin, and change in the hemolysis rate of erythrocytes before and after suction were compared. Additionally, the erythrocyte morphology was observed. RESULTS The hemoglobin and hematocrit were significantly different before and after suction in all five groups. As the suction pressure increased, gradual increases were noted in the number of abnormal erythrocytes in the field of view, the newly generated standardized plasma free hemoglobin, and the change in the hemolysis rate. CONCLUSIONS The destruction rate of erythrocytes increased as the suction-generated negative pressure increased. When using a pressure-control system, a negative pressure of <200 mmHg should be applied to reduce the damage to the autotransfused blood.

Abstract
INTRODUCTION Cell salvaging is well established in the blood management of cardiac patients, but there remain some concerns about its effects on perioperative bleeding and transfusion variables. This randomized controlled study investigated the potential effects of the centrifuged end-product on bleeding, transfusion rates, and other transfusion-related variables in adult cardiac surgery patients submitted to extracorporeal circulation. MATERIALS AND METHODS Patients were randomly chosen to receive (cell-salvage group, 99 patients) or not to receive (control group, 110 patients) the centrifuged product of a cell salvage apparatus. Bleeding and transfusion rates according to the universal definition of perioperative bleeding (UDPB) classification, postoperative hemoglobin, coagulation, and oxygenation indices were recorded and compared between the groups. RESULTS Both groups had almost identical bleeding and transfusion rates (median value: 2 units of red blood cells (RBC) and no units of fresh frozen plasma (FFP) and platelets (PLT) for both groups, p > 0.05). Patients in the cell-salvage group presented slightly higher hemoglobin concentrations (10.6 ± 1.1 vs. 10.1 ± 1.7 g/dL, p < 0.05, respectively) and a tendency towards better oxygenation indices (P(a)O(2)/F(i)O(2): 241 ± 94 vs. 207 ± 84, p=0.013) in the postoperative period albeit with a tendency for prolongation of prothrombin time (INR: 1.31 ± 0.18 vs. 1.26 ± 0.12, p=0.008). CONCLUSION Within the study's constraints, the perioperative use of the cell salvage concentrate does not seem to affect bleeding or transfusion variables, although it could probably ameliorate postoperative oxygenation in adult cardiac surgery patients. A tendency to promote coagulation disturbances was detected.

Abstract
OBJECTIVES To compare the clinical efficacy of robot of stereotactic assistant (ROSA) and frame-assisted stereotactic drilling and drainage for intracerebral hematoma in hypertensive intracerebral hemorrhage (HICH). METHODS A total of 142 patients with HICH treated in Baoding First Central Hospital from January 2018 to January 2020 were selected and divided into two groups using a random number table. The ROSA group was treated with a robot of stereotactic assistant, while the frame group underwent frame-assisted stereotactic drilling and drainage for intracerebral hematoma. Surgical duration, postoperative extubation time and complications were compared between the two groups. Venous blood (5 mL) was collected before and three days after surgery. The levels of inflammatory factors [tumor necrosis factor-α (TNF-α), high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6)], as well as neurological function indexes [neuron-specific enolase (NSE), nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF)] were detected by enzyme-linked immunosorbent assay. RESULTS The surgical duration, postoperative extubation time, and incidences of infection and postoperative rehemorrhage in the ROSA group were lower than those in the frame group (P < 0.05). In the ROSA group, postoperative TNF-α, hs-CRP, IL-6 and NSE levels were significantly lower while NGF and BDNF levels were higher than those in the frame group (all P < 0.05). CONCLUSION Compared with frame-assisted stereotactic drilling and drainage for intracerebral hematoma, ROSA in HICH treatment shortens the surgical duration and postoperative extubation time, reduces the risks of infection and rehemorrhage and decreases inflammatory level, which is helpful for the recovery of neurological function.

Scientific reports. 2022;12(1):881
Abstract
Suction drainage after primary total hip arthroplasties (THA) offers no benefits. Revision hip arthroplasties (RHA) are more demanding procedures and associated with greater blood loss compared to primary cases. There is still a lack of literature regarding the application of drainage in RHA. A total of 40 patients who underwent RHA were included in this prospective study. Simple randomization with an allocation ratio 1:1 was performed. Primary outcomes: total blood loss, hemoglobin drop, joint hematoma size in USG, infection. Secondary outcomes: blood transfusion rate, soft tissue hematomas, C-reactive protein levels, Visual Analogue Scale before and on 3rd day after surgery, Harris Hip Score before and 6 weeks after surgery. An intention to treat analysis was performed, with a 2-year follow up. Statistically significant differences between groups was in blood loss: drainage 1559.78 ml, non-drainage 1058.27 ml, (p = 0.029) and hemoglobin level on 1st day after surgery: drainage 10.58 g/dl, non-drainage 11.61 g/dl (p = 0.0496). In terms of the other analyzed parameters, statistical differences were not found. Our study revealed that the use of suction drainage may lead to higher blood loss in the early postoperative period. Further studies are needed to evaluate our results.

Annals of cardiac anaesthesia. 2022;25(2):133-140
Abstract
OBJECTIVE The study aimed to evaluate the effect of mild and moderate hemodilution during CPB on the neurocognitive dysfunction in patients undergoing coronary artery bypass grafting. DESIGN A randomized clinical study. SETTING Cardiac center. PATIENTS 186 patients scheduled for cardiac surgery with cardiopulmonary bypass. INTERVENTION The patients were classified into 2 groups (each = 93), Mild hemodilution group: The hematocrit value was maintained >25% by transfusion of packed-red blood cells plus hemofiltration during CPB. Moderate hemodilution group: the hematocrit value was maintained within the range of 21-25%. MEASUREMENTS The monitors included the hemofiltrated volume, number of transfused packed red blood cells, and the incidence of postoperative cognitive dysfunction. MAIN RESULTS The hemofiltrated volume during CPB was too much higher with mild hemodilution compared to the moderate hemodilution (p = 0.001). The number of the transfused packed red blood cells during CPB was higher with mild hemodilution compared to the moderate hemodilution (p = 0.001), but after CPB, the number of the transfused packed red blood cells was lower with the mild hemodilution group than the moderate hemodilution (p = 0.001). The incidence of total postoperative neurological complications was significantly lower with the mild hemodilution group than moderate hemodilution (p = 0.033). The incidence of neurocognitive dysfunction was significantly lower with mild hemodilution group than moderate hemodilution (p = 0.042). CONCLUSIONS The mild hemodilution was associated with a significant decrease in the incidence of neurocognitive dysfunction compared to moderate hemodilution in patients undergoing coronary artery bypass grafting. Also, the transfused packed red blood cells increased during CPB and decreased after CPB with the mild hemodilution than moderate hemodilution.

Abstract
Secondary spontaneous pneumothorax (SSP) patients sometimes have a persistent air leak (PAL) that leads to increased morbidity and increased hospital stay. Further, these patients also need pleurodesis to prevent a recurrence. Autologous blood patch pleurodesis (ABPP) has been successfully tried in post lobectomy air leak cases. However, its utility in SSP patients with PAL has not been widely established. In this context, we performed a non-blinded randomized control study to compare the efficacy of ABPP vs doxycycline pleurodesis in the closure of air leak in SSP patients. This study was a non-blinded randomized control study done in 38 SSP patients with PAL. They were randomized into doxycycline arm and ABPP arm. Post pleurodesis air leak was assessed every 12 hours for cessation. Success was considered when there was a complete cessation of air leak. Post-procedural complications were noted and patients were followed up for 28 days to look for recurrence. The median time for closure was 24 hours [interquartile range (12.24)] for ABPP and 36 hours [interquartile range (24.72)] for doxycycline pleurodesis. Success rate of ABPP vs doxycycline pleurodesis is 94.7% vs 84.2% (p=0.6). Post-procedure pain was more in doxycycline group (15% vs 73%) (p<0.01). On visual analogue scale, ABPP had a lesser pain as compared to doxycycline pleurodesis (average visual analogue scale value of 2 vs scale of 7). The recurrence rate was equal in both groups (5%). Though ABPP and doxycycline have similar success rates, ABPP has an early closure of air leak and greater patient tolerability. ABPP can be tried as an alternative to doxycycline pleurodesis in SSP patients with persistent air leaks.

Abstract
BACKGROUND AND OBJECTIVES Transfusion-associated circulatory overload (TACO) is a major cause of severe transfusion-related morbidity. Transfusion of red blood cells (RBCs) has been shown to induce hydrostatic pressure overload. It is unclear which product-specific factors contribute. We set out to determine the effect of autologous RBC transfusion versus saline on pulmonary capillary wedge pressure (PCWP) change. MATERIALS AND METHODS In a randomized crossover trial, patients who had undergone coronary bypass surgery were allocated to treatment post-operatively in the intensive care unit with either an initial 300 ml autologous RBC transfusion (salvaged during surgery) or 300 ml saline infusion first, followed by the other. Primary outcome was the difference in PCWP change. Secondary outcome measures were the difference in extra-vascular lung water index (EVLWI) and pulmonary vascular permeability index (PVPI). RESULTS Change in PCWP was not higher after autologous RBC transfusion compared to saline (ΔPCWP 0.3 ± 0.4 vs. 0.1 ± 0.4 mmHg). ΔEVLWI and ΔPVPI were significantly decreased after autologous RBC transfusion compared to saline (ΔEVLWI -1.6 ± 0.6 vs. 0.2 ± 0.4, p = 0.02; ΔPVPI -0.3 ± 0.1 vs. 0.0 ± 0.1, p = 0.01). Haemodynamic variables and colloid osmotic pressure were not different for autologous RBC transfusion versus saline. CONCLUSION Transfusion of autologous RBCs did not result in a more profound increase in PCWP compared to saline. RBC transfusion resulted in a decrease of EVLWI and PVPI compared to saline. Our data suggest that transfusing autologous RBCs may lead to less pulmonary oedema compared to saline. Future studies with allogeneic RBCs are needed to investigate other factors that may mediate the increase of PCWP, resulting in TACO.

Annals of cardiac anaesthesia. 2021;24(4):427-433
Abstract
BACKGROUND Although conventional cardiopulmonary bypass (cCPB) is still the most widely used method in open heart surgery, methods such as retrograde autologous priming (RAP) are increasingly popular in terms of limiting hemodilution. Our hypothesis is that the use of the RAP method in aortic surgery may result in a limitation of hemodilution and a decrease in fHb levels. For this purpose, plasma free hemoglobin (fHb) levels were investigated in adult open aortic arch repair with axillary artery cannulation patients using cCPB and rRAP methods. MATERIALS AND METHODS In this study, a total of 36 patients undergoing aortic surgery using rRAP and standard cCPB were investigated. Measurements were performed at five time points: After induction of anesthesia, 5(th) minute of CPB, 10(th) minute of antegrade cerebral perfusion, 30(th) minute after declamping of aorta, and at sternum closure. Besides hemodynamic variables, arterial blood gas analysis and postoperative variables, patients were assessed for fHb levels. RESULTS The rRAP group had a significantly lower increase in fHb levels in T3, T4, and T5 time points, when compared to the cCPB group (p = 0.002, 0.047, 0.009, respectively). There was no significant difference between the rRAP and cCPB groups in other intraoperative, and postoperative variables. Also, it was observed that rRAP did not make a difference in terms of blood and blood product transfusion. CONCLUSION In this study, in patients undergoing aortic surgery, a reduction in the increase of fHb was observed with the rRAP method which is a simple procedure that does not require high cost or advanced technology.
