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.

Pakistan journal of medical sciences. 2022;38(7):1796-1801
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.

BMC neurology. 2021;21(1):268
Abstract
BACKGROUND Minimally invasive surgery has achieved good results in the treatment of cerebral haemorrhage.However, no large-scale clinical study has demonstrated that surgical treatment of cerebral haemorrhages less than 30 ml can improve the curative effect. Our study explored the efficacy and complication of stereotactic drainage based on the amount of cerebral hemorrhage (15-30 ml) in hypertensive basal ganglia. METHOD Sixty patients with hypertensive basal ganglia haemorrhages were divided into a control group and an experimental group with 30 patients in each group. Patients in the control group were treated conservatively. In contrast, those in the experimental group received stereotactic drainage, and urokinase was injected into the haematoma cavity after the operation. The haematoma volume at admission and 1, 3, 7 and 30 days after treatment and National Institute of Health stroke scale(NIHSS) score data were recorded. Complications after treatment in the two groups of data were compared and analysed. RESULT No significant differences in age, sex, time of treatment after onset, admission blood pressure, admission haematoma volume or admission NIHSS score were noted between these two groups (P > 0.05). After treatment, significant differences in haematoma volume were noted between the two groups on the 1st, 3rd, 7th and 30th days after treatment (P < 0.05). The amount of hematoma of patients in the experimental group was significantly reduced compared with that in the control group, and the NIHSS scores were significantly different on the 3rd, 7th and 30th days after treatment. The neurological deficit scores of patients in the experimental group were significantly reduced compared with those in the control group, and the incidence of pulmonary infection and venous thrombosis in the lower limbs of patients in the experimental group were significantly reduced (P < 0.05). ROC curve analysis showed that stereotactic drainage affected the early neurological function of patients with small and medium basal ganglia haemorrhages. CONCLUSION For patients with small and medium basal ganglia haemorrhages, stereotactic drainage can be used due to the faster drainage speed of haematomas after operation, which is beneficial to the recovery of neurological function and reduce complications.

Abstract
Objective: Chronic subdural hematoma (CSDH) is a common disease. Atorvastatin calcium can increase CSDH absorption. However, whether atorvastatin can increase hematoma absorption and reduce recurrence at high altitudes is not clear. Methods: After burr-hole drainage, CSDH patients were divided into an atorvastatin group and a control group. Follow-up computed tomography (CT) was performed on day 1, months 1, 2, and 3 after surgery. Then, the recurrence rate, poor therapeutic effect, time to recurrence, poor surgical result, recurrence with operation, CSDH volume, and Markwalder grading scale score (MGSS) were calculated, and related risk factors were analyzed. Results: The non-recurrent and recurrent patients in the control group differed significantly in terms of the hemoglobin concentration (HB) [176.24 +/- 16.43 vs. 194.25 +/- 12.34 (g/L), p < 0.01], CT value [41.92 +/- 10.76 vs. 34.12 +/- 8.78 (Hu), p < 0.01], and low-density time [3.88 +/- 1.04 vs. 5.50 +/- 0.87 (d), p < 0.01]. The non-recurrent and recurrent patients in the atorvastatin group differed significantly in terms of the HB [172.66 +/- 16.41 vs. 190.45 +/- 10.23 (g/L), p < 0.01], CT value [38.91 +/- 7.16 vs. 29.50 +/- 8.61 (Hu), p < 0.01], and mixed [2 vs. 4 (n), p < 0.05] and low-density time [4.09 +/- 0.75 vs. 5.45 +/- 1.12 (d), p < 0.01]. The logistic regression analysis showed that HB [odds ratio, 1.14; 95% confidence interval (CI), 1.04-1.25 in the control group, odds ratio, 1.13; 95% CI, 1.03-1.23 in the atorvastatin group] and low-density time (odds ratio, 3.53; 95% CI, 1.42-8.74 in the control group, odds ratio, 2.53; 95% CI, 1.10-5.80 in the atorvastatin group) were possible risk factors for the two groups. The receiver operating characteristic curves showed that the area under the receiver operating characteristic curve values for the HB, CT value (Hu), and low-density time were 0.812, 0.702, and 0.755 for all subjects; 0.812, 0.719, and 0.790 for the control group; and 0.807, 0.682, and 0.756 for the atorvastatin group, respectively. The postoperative follow-up results showed that there was no significant difference in the recurrence rate, poor therapeutic effect, time to recurrence, poor surgical result, recurrence with operation, CSDH volume, or MGSS between the two groups. Conclusion: The effect of atorvastatin was not significant after the operation. The risk factors for CSDH recurrence were the HB and low-density time. The HB was the most specific and sensitive predictor of CSDH recurrence.

Abstract
BACKGROUND To evaluate and analyze the therapeutic effect of stereotactic soft channel puncture and drainage on hypertensive cerebral hemorrhage. METHODS Sixty patients with hypertensive cerebral hemorrhage admitted to our hospital from September 2014 to September 2019 were selected for study and randomly divided into study group (n=30) and routine group (n=30) according to admission number. Two groups of patients were given basic treatment after admission, while routine group patients were given small bone window hematoma removal, study group patients were given stereotactic soft channel puncture and drainage, and the clinical effects of the two groups were analyzed. RESULTS The total effective rate of the study group was 96.67%, which was significantly higher than that of the routine group (80.00%), and the difference was statistically significant (P<0.05). The level of independent living in the study group was significantly higher than that in the conventional group, and the level of neurological deficit was lower than that in the conventional group, with statistically significant difference (P<0.05). Before treatment, there was no significant difference in the hematoma volume between the two groups (P>0.05). after treatment for 1, 2 and 4 weeks, the hematoma volume of the two groups decreased, and the hematoma volume of the study group was significantly less than that of the conventional group, with significant difference (P<0.05). There was no difference in CD3+ positive cell rate and CD8+ positive cell rate between the two groups before treatment (P>0.05). After treatment, the CD8+ positive cell rate in the study group was lower than that in the conventional group, and the CD3+ positive cell rate was higher than that in the conventional group, with statistically significant difference (P<0.05). The incidence of postoperative complications such as pulmonary infection, urinary tract infection, liver and kidney dysfunction in the study group was lower than that in the conventional group, and the difference was statistically significant (P<0.05). CONCLUSIONS Stereotactic soft-channel puncture and drainage has the advantages of less trauma, less bleeding, fewer complications and rapid postoperative recovery. It can be used for the treatment of hypertensive cerebral hemorrhage, promote the recovery of neurological function of patients, improve independent living standard and effectively improve prognosis.

Endoscopic Surgery for Thalamic Hemorrhage with Intraventricular Hemorrhage: Effects of Combining Evacuation of a Thalamic Hematoma to External Ventricular Drainage
Shimizu Y, Tsuchiya K, Fujisawa H
Asian journal of neurosurgery. 2019;14(4):1112-1115
Abstract
Objectives: Intraventricular hemorrhage (IVH) caused by thalamic hemorrhage leads to hydrocephalus, increased intracranial pressure, and reduced levels of consciousness. The aim of this study was to investigate the efficacy and compare the results of endoscopic surgery for the evacuation of a thalamic and intraventricular hematoma against those of external ventricular drainage (EVD) surgery. Materials and Methods: From January 2010 to December 2018, 68 patients with IVH caused by thalamic hemorrhage were treated in our department. Our study was approved by the Institutional Ethics Committee. The included patients were randomly divided into an EVD group and an endoscopic surgery group. The outcome was measured after 3 months using a 30-day mortality rate, pneumonia onset rate, ventriculoperitoneal (VP) shunt dependency rate, and Glasgow Outcome Scale (GOS) score. Results: Thirty-eight of the 68 patients were randomly assigned to the endoscopic surgery group and 30 were assigned to the EVD group. Patients treated with endoscopic surgery had significantly less drainage dependency on day 30 (P = 0.00014 < 0.00005) in comparison to those treated with EVD. The difference in the functional outcomes between the two groups of patients was mainly dependent on the onset of pneumonia and the consciousness level at the time of admission. The onset rate of aspiration-related pneumonia until day 30 was 11% in the endoscopic surgery group and 45% in the EVD group. The VP shunt rates were 27.8% in the endoscopic surgery group and 60% in the EVD group. The endoscopic surgery group had a significantly lower VP shunt rate compared with the EVD group. Intracerebral hemorrhage evacuation late was found to be associated with shunt-dependent rate and hospitalization. Conclusions: Endoscopic surgery was found to be associated with a lower GOS score and lower onset rates for shunt-dependent hydrocephalus and aspiration-related pneumonia in comparison to EVD. High evacuation rate was associated with lower shunt-dependent rate and short hospitalization.

Hasan MS, Choe NC, Chan CYW, Chiu CK, Kwan MK
Journal of Orthopaedic Surgery (Hong Kong). 2017;25((2)):2309499017718951.
Abstract
BACKGROUND Massive blood loss during posterior spinal fusion for adolescent idiopathic scoliosis remains a significant risk for patients. There is no consensus on the benefit of acute normovolemic hemodilution (ANH) or intraoperative cell salvage (ICS) in scoliosis surgery. METHODS Patients were randomized to one of two groups. Group A received ANH and ICS during operation, while group B received only ICS. Patients' age, sex, height, weight, body blood volume, number of fusion level, Cobb angle, number of screws, duration of surgery, and skin incision length were recorded. Hemoglobin and hematocrit levels were obtained preoperatively and postoperatively (0 h and 24 h). RESULTS There were 22 patients in each group. There was no significant difference in total blood loss. The perioperative decrease in hemoglobin levels between preoperation and postoperation 24 h (group A 2.79 +/- 1.15 and group B 2.76 +/- 1.00) showed no significant difference ( p = 0.93). Group A observed a larger decrease in hemoglobin levels at postoperative 0 h relative to preoperative level (2.57 +/- 0.82 g/dl), followed by a smaller decrease within the next 24 h (0.22 +/- 1.33 g/dl). Group B showed a continued drop in hemoglobin levels of similar magnitude at postoperation 0 h (1.60 +/- 0.67 g/dl) and within the next 24 h (1.16 +/- 0.78 g/dl). One patient from group B received 1 unit of allogenic blood transfusion ( p = 0.33). CONCLUSIONS The addition of ANH to ICS in posterior spinal fusion surgery for AIS resulted in a similar decrease in hemoglobin levels between preoperative values and at 24 h postoperatively.

Abstract
The aim of this study was to evaluate the safety of acute normovolemic hemodilution (ANH) for patients undergoing intracranial meningioma resection.Eighty patients (aged 48-65 years) with American Society of Anesthesiologists physical status I-II undergoing intracranial meningioma resection were included in this prospective observational study. The patients were randomly divided into group A (ANH group), which underwent a combination of ANH and intraoperative cell salvage (ICS), and group B (control group), which underwent ICS alone. The study parameters were recorded as baseline values before blood drainage (T0), after blood drainage (T1), and before (T2) and after (T3) retransfusion in group A. Whereas in group B, the same parameters were measured 10 minutes after anesthesia induction (T0), before surgery (T1), and before (T2) and after (T3) transfusion of autologous blood.When intraoperative blood loss was <2000 mL, the mean volume of homologous blood transfused in group A patients was 100.8 +/- 82.3 mL, compared with the 190.0 +/- 91.8 mL in group B. Reduction in homologous blood used in group A was statistically significant (P < .05). In group B, 15.1% patients received homologous blood, whereas only 5.9% patients received homologous blood in group A. The difference in heart rate between both groups at different time points was statistically nonsignificant (P > .05). The mean hemoglobin and hematocrit levels at T1 and T2 in group A were lower than in group B (P < .05). The prothrombin time and activated partial thromboplastin time in both groups were prolonged significantly after T2 (all P < .05), but were all within normal range. There were no significant differences in postoperative hospital stay, mortality, and postoperative infection between the 2 groups.For patients undergoing excision of intracranial meningioma, ANH is an effective procedure to reduce the need for allogeneic transfusions.

Abstract
Study Design Systematic review. Objective Determine whether closed suction wound drains decrease the incidence of postoperative complications compared with no drain use in patients undergoing spine surgery for lumbar degenerative conditions. Methods Electronic databases and reference lists of key articles were searched up through January 22, 2015, to identify studies comparing the use of closed suction wound drains with no drains in spine surgery for lumbar degenerative conditions. Outcomes assessed included the cumulative incidence of epidural hematoma, superficial and deep wound infection, and postoperative blood transfusion. The overall strength of evidence across studies was based on precepts outlined by the Grades of Recommendation Assessment, Development and Evaluation Working Group. Results Five heterogeneous studies, three randomized controlled trials, and two cohort studies form the evidence basis for this report. There was no difference in the incidence of hematoma, superficial wound infection, or deep infection in patients with compared with patients without closed suction wound drains after lumbar surgery. The upper bounds of the 95% confidence interval for hematoma ranged from 1.1 to 16.7%; for superficial infection, 1.0 to 7.3%; and for deep infection, 1.0 to 7.1%. One observational study reported a 3.5-fold increase in the risk of blood transfusion in patients with a drain. The overall strength of evidence for these findings is considered low or insufficient. Conclusions Conclusions from this systematic review are limited by the quality of included studies that assessed the use of closed suction wound drains in lumbar spine surgeries for degenerative conditions. We believe that spine surgeons should not routinely rely on closed suction wound drains in lumbar spine surgery until a higher level of evidence becomes available to support its use.

Tamai K, Terai H, Toyoda H, Suzuki A, Yasuda H, Dozono S, Nakamura H
Scoliosis. 2015;10((Suppl 2)):S11.
Abstract
BACKGROUND It is critically important for AIS patients to avoid perioperative allogeneic blood transfusions. Toward this aim, many institutes use autologous blood storage to perform perioperative transfusions. However, there is no standard timeline for collecting blood for storage. Therefore, the objective of this prospective cohort study was to compare the outcome of two different schedules for collecting autologous blood before operation in adolescent idiopathic scoliosis (AIS) patients. METHODS Inclusion criteria are AIS patients, younger than 20 years old, female, operated between 2009 and 2013 with posterior spinal fusion and instrumentation who had 1600 mL autologous blood collected before operation. A total of 61 patients were participated in this study. They were randomly divided into 2 groups based on the storage interval. Weekly group (1W-G) consisted of 30 patients with a total of 1600mL blood collected weekly beginning 4 weeks before the operation. Biweekly group (2W-G) consisted of 31 patients with a total of 1600 mL blood collected biweekly beginning 8 weeks before the operation. The instrumented levels, total bleeding, complications during blood transfusion, and hematological examinations (RBC, Hb, Hct, MCH, MCV, MCHC) were evaluated. A hematological examination was performed before blood collection, before the operation, and on postoperative days 1, 3, and 7. Vasovagal reflex (VVR) was evaluated as complications during blood drawing. RESULT Mean age, height, and weight did not differ significantly between the 2 groups. There were no significant differences in instrumented levels, bleeding during operation, after operation, and collected blood during operation. With the autologous blood, allogeneic blood transfusion was completely avoided. VVR was more frequent in the biweekly group significantly (1W-G 4.2% vs 2W-G 15.3%). In terms of hematological examination, all values showed no significant differences between two groups in the pre-drawing and the pre-operation stage. However, the postoperative Hb and Hct values were higher in the weekly group. Also, MCV and MCHC showed the same behavior with higher values in the weekly group. CONCLUSION A weekly schedule of autologous blood storage is better than a biweekly storage schedule.
