Intraoperative Bleeding In Patients Research Articles

Analysis of risk factors for intraoperative bleeding in patients with Siewert type II esophagogastric junction adenocarcinoma treated by two minimally invasive surgeries and its influence on prognosis: a retrospective study.

The present study aimed to analyze the independent risk factors for intraoperative bleeding in Siewert II adenocarcinoma of the esophagogastric junction (AEG) using two minimally invasive surgical approaches, namely, the laparoscopy-assisted abdominal trans-hiatal (LTH) method and transthoracic-laparoscopic esophagectomy (TLE). The clinical data of 100 patients with SiewertII AEG admitted to our hospital from October 2017 to October 2020 were retrospectively analyzed. According to the type of surgery, the patients were divided into LTH approach group and TLE approach group. The differences between the clinical characteristics of the patients in different groups and the differences in the intraoperative bleeding and prognosis between different surgical procedures were analyzed and compared using the t-test and chi-squared test. Multiple linear regression was used to identify the independent risk factors affecting the amount of intraoperative bleeding in patients. The results of this study showed that patients in the LTH group had significantly less intraoperative bleeding and operative time and significantly better postoperative recovery than the TLE group. The results of multivariate linear regression showed that the combined trans-thoracic-abdominal approach (P=0.000), advanced age (P=0.014), larger BMI (P=0.000), and larger tumor diameter (P=0.001) were the independent risk factors influencing the increase in intraoperative bleeding. In addition to the conventional factors that affect intraoperative bleeding, such as the patient's general condition, operation time, and tumor size, LTH surgery is another way to avoid intraoperative bleeding for Siewert type II AEG patients and can significantly improve postoperative recovery.

The Role of Tranexamic Acid (TXA) In Spine Surgery for Patients with Comorbidities in Basra/Iraq

Background: Blood loss occurs frequently and remains a challenge in spinal surgery. As significant intra and postoperative hemorrhage negatively affects patient outcomes by increasing coagulopathy, postoperative hematoma, and anemia. The need for allogenic blood transfusions can lead to potential transfusion reactions and infections, in addition to increasing long-term mortality rates. Although there are many randomized control trials and meta-analysis investigating the role of tranexamic acid (TXA), we could not find any study that investigated the role of TXA in patients with medical comorbidities. Therefore, tackling the role of TXA in patients with single or multiple comorbidities is of valuable outcome to our locality as most of the patients have indeed associated comorbidities. Objectives: to investigate the role of tranexamic acid in decreasing perioperative blood loss in patients with multiple comorbidities as compared to otherwise healthy individuals. Patients and methods: A single center randomized control trial. We included patients that were about to undergo simple decompressive surgeries for lumbar canal stenosis and fixation with decompression for spondylolisthesis. Patients were randomly categorized into cases (who received TXA) and controls who received NS. Patients then were subcategorized according to comorbidities and types of surgeries. Intraoperative blood loss was calculated using the suction drain and the gauze while the post operative bleeding was calculated using the drain output. Results: There was 441.84 ml (49.6 %) decrease in intraoperative bleeding for patients who received TXA as compared to controls regardless the type of surgery and regardless the presence or absence of comorbidities. Hypertensive patients had 52.7 % reduction in intraoperative bleeding when received TXA, Diabetic patients showed 44.4 % reduction in bleeding, Obese patients showed 51.1% reduction and patients with multiple comorbidities showed 51% reduction in intraoperative bleeding while healthy individuals showed 38.9% reduction in intraoperative bleeding. Conclusion: TXA was even more effective in decreasing intraoperative bleeding in patients with multiple comorbidities as compared to healthy individuals.

Effectiveness Of Platelet Markers In Estimating The Amount Of Intraoperative Bleeding In Vertebra Surgery

AIMS: One of the most important steps in perioperative bleeding management is the predetermination of the patient at risk. Even if there is no hemostatic abnormality in vertebral surgery, which is a major surgery, severe bleeding can be encountered and many perioperative blood transfusions might be required. To date, there are no studies in the literature examining platelet markers in terms of predictivity in intraoperative bleeding during vertebral surgeries. In this study; we investigated the effectiveness of preoperative mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT), mean platelet volume lymphocyte count ratio (MPVLR), and platelet count to lymphocyte count ratio (PLR) values in predicting the amount of intraoperative bleeding in patients who will undergo vertebral surgery. 
 METHODS: After the approval from the ethics committee, patients who were planned for vertebral surgery by the neurosurgeon were identified. Patient demographic data such as gender, age, ASA score and body mass index (BMI), MPV, PDW, PCT, MPVLR, and PLR values were recorded. Total surgery time, the number of vertebral transpedicular screwing, and laminectomy levels performed as surgical procedures were recorded. The amount of intraoperative bleeding was determined by calculating the amount of blood accumulated in the aspirator and the amount of blood collected by the sponge during surgery. 
 RESULTS: Of the 63 patients included in the study, 60.3% (n=38) were female and 39.7% (n=25) were male. The mean age of the patients was 54.7 ± 11 years and the mean BMI was 29.6 ± 4.6. No correlation was found between the amount of bleeding and gender, age, MPV, PDW, PCT, MPVLR, or PLR values. A significantly high correlation was found between amount of bleeding and BMI, duration of surgery, and the number of transpedicular screwing segments. 
 CONCLUSION: Platelet markers do not appear to have an effect on the amount of bleeding. However, as the BMI increases, the duration of surgery prolongs and the number of transpedicular screw segments increases for which the amount of bleeding increases.

Possibilities of Transfistula Ultrasound in Predicting Intraoperative Bleeding in Patients with Infected Pancreatic Necrosis

Introduction. Assessing the risk of intraoperative bleeding is of great importance in the treatment of patients with infected pancreatic necrosis.The aim of the study — determine the role of transfistula ultrasound in assessing the risk of intraoperative bleeding in patients with infected pancreatic necrosis.Materials and methods. From 2015 to 2019, 193 people with infected pancreatic necrosis were treated at Regional Clinical Hospital No. 2 (Krasnodar). At stage 1, drains of various diameters were installed in all patients; at stage 2, necrotic tissue was removed using transfistula videoscopic necrosequestrectomy in 48 patients (24.9 %). Before performing instrumental necrosequestrectomy, a developed diagnostic method was used — transfistula ultrasound scanning — to determine the relationship between the location of foci of necrosis in the pancreas and blood vessels in 22 patients (11.4 %; group 1); the method was not used in 26 people (13.5 %; group 2).Results. The number of accesses created into the omental bursa was as follows: 141 patients (73.1 %) had 3 accesses, 52 people (26.9 %) had 2 accesses; into the retroperitoneal space: 102 patients (52.8 %) had 2 accesses, 51 people (26.4 %) had 1 access. Transfistula videoscopic necrosequestrectomy was performed 35 and 37 times in groups 1 and 2, respectively (p > 0.05). Transfistula ultrasound scanning to assess the risk of intraoperative bleeding was used 33 times in patients in group 1. In group 1, intraoperative bleeding was observed in 5 patients (23.8 %), in group 2 — in 7 patients (26.9 %) (p > 0.05). The volume of blood loss was (436.0±83.6) and (887.0±41.8) ml in groups 1 and 2, respectively (p < 0.05). There were no cases of death due to intraoperative bleeding in either group.Discussion. Transfistula ultrasound scanning makes it possible to stratify patients: into a high-risk group (with intimate adjacency of necrosis to vessels), medium (at a distance of up to 15 mm) and low-risk (with a distant location). In this regard, interventions in high-risk patients were carried out in the X-ray operating room to allow for endovascular hemostasis, which made it possible to reduce the volume of blood loss, as well as to create a supply of transfusion media in advance to replenish the volume of blood volume.Conclusion. The developed method of direct transfistula ultrasound scanning makes it possible to assess the risk of intraoperative bleeding in patients with infected pancreatic necrosis to achieve timely hemostasis and compensate for acute blood loss.

Development and validation of a machine learning-based early prediction model for massive intraoperative bleeding in patients with primary hepatic malignancies.

Surgical resection remains the primary treatment for hepatic malignancies, and intraoperative bleeding is associated with a significantly increased risk of death. Therefore, accurate prediction of intraoperative bleeding risk in patients with hepatic malignancies is essential to preventing bleeding in advance and providing safer and more effective treatment. To develop a predictive model for intraoperative bleeding in primary hepatic malignancy patients for improving surgical planning and outcomes. The retrospective analysis enrolled patients diagnosed with primary hepatic malignancies who underwent surgery at the Hepatobiliary Surgery Department of the Fourth Hospital of Hebei Medical University between 2010 and 2020. Logistic regression analysis was performed to identify potential risk factors for intraoperative bleeding. A prediction model was developed using Python programming language, and its accuracy was evaluated using receiver operating characteristic (ROC) curve analysis. Among 406 primary liver cancer patients, 16.0% (65/406) suffered massive intraoperative bleeding. Logistic regression analysis identified four variables as associated with intraoperative bleeding in these patients: ascites [odds ratio (OR): 22.839; P < 0.05], history of alcohol consumption (OR: 2.950; P < 0.015), TNM staging (OR: 2.441; P < 0.001), and albumin-bilirubin score (OR: 2.361; P < 0.001). These variables were used to construct the prediction model. The 406 patients were randomly assigned to a training set (70%) and a prediction set (30%). The area under the ROC curve values for the model's ability to predict intraoperative bleeding were 0.844 in the training set and 0.80 in the prediction set. The developed and validated model predicts significant intraoperative blood loss in primary hepatic malignancies using four preoperative clinical factors by considering four preoperative clinical factors: ascites, history of alcohol consumption, TNM staging, and albumin-bilirubin score. Consequently, this model holds promise for enhancing individualised surgical planning.

Endovascular occlusion of a persistent stapedial artery prior to stapedotomy: a novel approach.

The stapedial artery is an embryonic artery that transiently supplies the cranial vasculature of the human embryo. Postnatal persistence of the stapedial artery may cause conductive hearing loss and pulsatile tinnitus due to its course through the middle ear. We describe a patient with a persistent stapedial artery (PSA) managed by endovascular coil occlusion prior to stapedotomy. A 48-year-old woman presented with left-sided conductive hearing loss and pulsatile tinnitus. Ten years earlierthe patient had undergone explorative tympanoplasty, which was aborted due to a large PSA. Digital subtraction angiography was performed to confirm the anatomy and endovascular occlusion of the proximal PSA was achieved by deployment of coils. The pulsatile tinnitus improved immediately after the procedure. The size of the artery subsequently decreased and surgery could be performed with only a minor intraoperative bleeding. Successful stapedotomy resulted in postoperative normalization of her hearing with some minor residual tinnitus. Endovascular coil occlusion of a PSA is feasible and safe in patients with favorable anatomy and facilitates middle ear surgery. It decreases the size of the artery and minimizes the risk of intraoperative bleeding in patients with a large PSA. Thefuture role of this novel technique in the management of patients with PSA-related conductive hearing loss and pulsatile tinnitus remains to be determined.

Multi-Port Robotic-Assisted Laparoscopic Myomectomy: A Systematic Review and Meta-Analysis of Comparative Clinical and Fertility Outcomes.

Uterine fibroids are the most frequently diagnosed gynaecological tumours, and they often require surgical treatment (conventional laparoscopic myomectomy-CLM). The introduction and evolution of robotic-assisted laparoscopic myomectomy (RALM) in the early 2000s has expanded the range of minimally invasive options for the majority of cases. This study aims to compare RALM with CLM and abdominal myomectomy (AM). Fifty-three eligible studies adhered to the pre-established inclusion criteria and were subsequently evaluated for risk of bias and statistical heterogeneity. The available comparative studies were compared using surgical outcomes, namely blood loss, complication rate, transfusion rate, operation duration, conversion to laparotomy, and length of hospitalisation. RALM was significantly superior to AM in all assessed parameters other than operation duration. RALM and CLM performed similarly in most parameters; however, RALM was associated with reduced intra-operative bleeding in patients with small fibroids and had lower rates of conversion to laparotomy, proving RALM as a safer overall approach. The robotic approach for surgical treatment of uterine fibroids is a safe, effective, and viable approach, which is constantly being improved and may soon acquire widespread adoption and prove to be superior to CLM in certain patient subgroups.

The Influence of Resection Size and Pringle Maneuver on Operating Time and Intraoperative Bleeding in Patients with Colorectal Metastases in the Liver

BACKGROUND: The extent of the resection, whether clamped or non-clamping resection is factor that influences the operating time and intraoperative bleeding, the development of modern techniques for vascular control and resection, and determine of lesser blood loss, morbidity, and mortality. AIM: The aim of this study was to determine the experience of General and Hepatobiliary Surgery Clinic at Aleksandrovska Hospital Sofia, Republic of Bulgaria in the treatment of patients with colorectal metastases in the liver and to compare literature reports on the influence of the extent of resection and Pringle maneuver (IPM) on operating time and perioperative bleeding. MATERIALS AND METHODS: This retrospective study covers the time period from January 01, 2006, until December 31, 2015. A total of 239 patients were included, from which: 179 patients were treated with radical surgery, 5 with palliative intervention, and 55 were subjected on operability exploration. RESULTS: The use of the IPM for vascular control insignificantly influenced the prolonged operative time, while intraoperative blood loss was significantly lower in patients with Pringle &lt;15 min. There was no association between IPM and resection type, while intraoperative blood loss and operating time were significantly greater in patients with major resection. CONCLUSION: Resection size is directly proportional to operating time and perioperative blood loss, but it does not significantly influence perioperative morbidity. The IPM does not influence operating time, while blood loss is significantly lower in the group of patients with Pringle &lt;15 min.

Correlation of Thromboelastography Functional Fibrinogen and Severity of Intraoperative Bleeding in Patients Undergoing Revascularization with Peripheral Artery Disease

Efficacy of Cold Tumescent for Prevention of Intraoperative Bleeding in Patients Undergoing Liposuction: A Double-Blind Randomized Controlled Trial-Half-Side Comparison.

Bleeding, a common intraoperative complication of liposuction, often causes pain and discomfort during recovery. Because of the vasoconstrictive effect of adrenaline in the tumescent solution, bleeding can be reduced; however, reports of postoperative bleeding persist. Cold temperatures also have a vasoconstrictive effect. This study aimed to determine the efficacy of cold tumescent solution in preventing and reducing intraoperative bleeding. This prospective randomized controlled trial was conducted between June 2018 and June 2019. The liposuction areas in each participant were divided into left and right sides; one side received operative room temperature tumescent solution (25 °C), and the other side received low-temperature tumescent solution (4 °C). The areas of ecchymosis, pain scores, and patient and surgeon satisfaction scores were compared and analyzed. Ten patients with 36 pairs of liposuction areas were enrolled in the study. Cold tumescent liposuction resulted in a significantly lower lipocrit than was obtained on the standard tumescent side (1.56 ± 0.69 vs 2.92 ± 0.94; P < .001). The ecchymosis area and pain score were significantly lower in the cold tumescent group on days 2, 4, 7, and 14. The satisfaction evaluation scores did not differ between patients and surgeons at 12 months postoperatively. The use of cold tumescent anesthesia significantly improved liposuction outcomes by reducing the intraoperative blood loss and the postoperative ecchymosis and pain, with no immediate or short-term complications in low-volume liposuction (<1000 mL) procedures. Furthermore, it generated a standard outcome and good patient satisfaction scores.

Association between cervical length and massive intraoperative bleeding in patients with suspected placenta accreta spectrum combined with placenta previa: A retrospective cohort study.

Abnormal placentation is a spectrum disorder that includes creta, increta, and percreta; the term placenta accreta spectrum (PAS) disorders is used as a broad term to describe all of these conditions. PAS can lead to life-threatening hemorrhage. The predictive value of cervical length (CL) in patients with PAS remains controversial. Thus, this study investigated the relationship between CL and the probability of major bleeding in patients with PAS and placenta previa. This retrospective cohort study was conducted at a comprehensive tertiary hospital in Chongqing, China, between January 2018 and December 2020. The target independent and dependent variables were CL and intraoperative massive bleeding, respectively. The covariates included demographic, clinical, and ultrasound characteristics. Logistic regression was used to explore the association between CL and massive bleeding. In total, 317 participants were enrolled, in whom the prevalence of massive bleeding was 41.9% (133/317). The threshold of CL associated with massive bleeding (≥1,000 ml) was 33 mm based on a receiver operating characteristic curve. In the fully adjusted model for each additional unit of CL, the risk of massive bleeding decreased by 7% [95% confidence interval (CI), 0.88-0.98]. The risk of major bleeding was reduced by 44% in patients with a CL greater than 33 mm (95% CI, 0.33-0.97) compared with patients with a CL less than 33 mm. CL was negatively associated with massive intraoperative bleeding in patients with PAS combined with placenta previa. When the CL was greater than 33 mm, the risk of bleeding decreased by 44%. Thus, CL can be used as a standalone parameter to identify the risk of massive intraoperative bleeding in patients with suspected PAS.

Efficacy of low extra-abdominal aortic block in cesarean section for placenta accreta spectrum disorders and its effect on the expression of MDA and SOD.

Placenta accreta spectrum disorders (PAS) refers to a group of abnormalities in placental adhesion and invasion, which may lead to serious complications such as intractable postpartum hemorrhage. The use of low-level extra-abdominal aortic temporary block during cesarean section may reduce intraoperative bleeding in patients with PAS, but it may also cause ischemia-reperfusion injury. In this study, we intend to investigate the efficacy of low extra-abdominal aortic block in cesarean section for placental implantation disease and its effect on malondialdehyde (MDA) level and superoxide dismutase (SOD) activity, and analyze the severity of ischemia-reperfusion injury caused by them. Pregnant women with invasive placenta accreta spectrum disorders who delivered in the Department of Obstetrics and Gynecology of the Third Xiangya Hospital of Central South University from July 2017 to July 2021, were selected, and they were divided into 2 groups. Group A consisted of those who underwent low extra-abdominal aortic block during cesarean section (n=15) and group B consisted of those who did not undergo extra-abdominal aortic block (n=15). The intraoperative bleeding, blood transfusion, hysterectomy and complication rate, postoperative hospital stay and hospitalization expenses were compared between the 2 groups to analyze the efficacy of abdominal aortic block. The biochemical indexes related to ischemia-reperfusion, MDA content and total superoxide dismutase (T-SOD) activity, were measured at the corresponding time points in both groups. The time points of each test were: in group A, before the block of the low extra-abdominal aorta after delivery (A0), 0 h (A1, when the myometrium was started to be sutured), 0.5 h (A2), 2 h (A3), and 4 h (A4) after the open block; in group B, after delivery of the fetus (B0), 0 h (B1), 0.5 h (B2), 2 h (B3), and 4 h (B4) after the myometrium was started to be sutured. Total duration of abdominal aortic block in group A was also recorded. Both groups were observed for sings of edema, ischemia, necrosis and infection in the limbs after surgery. The severity of ischemia-reperfusion injury caused by abdominal aortic block were determined by detecting the relevant biochemical indexes at different moments of reperfusion. The intraoperative bleeding and blood transfusion in group A were less than those in group B, and the difference was statistically significant (P<0.05). There was no significant difference in postoperative hospital stay and hospitalization expenses between the 2 groups (P>0.05). Surgical complications: in group A, the uterus was preserved in all cases, there was 1 bladder injury and 2 pelvic infections; while in group B, there was 1 hysterectomy, 3 bladder injuries, and 3 pelvic infections. Changes in T-SOD and MDA values: compared with A0 before block, the MDA level was significantly elevated in blood at time points A1, A2, and A3, while SOD activity was significantly decreased (P<0.05), and the 2 observed indexes basically returned to A1 level (ischemic period) at 4 h after open block (A4). There was no significant difference in the changes of T-SOD and MDA in group B (P>0.05). Comparison of T-SOD and MDA levels between group A and B: the difference of the 2 indexes was not statistically significant between A0 and B0 (P>0.05), MDA level was not statistically significant between A1 and B1, T-SOD activity at A1 was lower than B1, the difference was statistically significant, at the rest of the same time point, MDA level in group A were higher than that in group B, T-SOD activity in group A were lower than that in group B, the difference was statistically significant (P<0.05). No postoperative limb edema, ischemia, necrosis, or infection occurred in both groups. Low-level extra-abdominal aortic block effectively reduces bleeding and transfusion during cesarean section for placenta accreta spectrum disorders, resulting in a transient MDA elevation and a decrease of SOD activity, which means causing transient ischemia-reperfusion injury without complications such as limb edema, ischemia, necrosis, and infection.

Outcome of pars plana vitrectomy with pre-operative intra vitreal bevacizumab in diabetic patients with vitreous haemorrhage

Background: Intravitreal bevacizumab causes regression of retinal neo vessels in proliferative diabetic retinopathy as it is anti-vascular endothelial growth factor (anti VEGF). So this study was done to observe the effect of pre-operative intravitreal bevacizumab on intra operative outcome when administered in patients with vitreous hemorrhage undergoing pars-plana vitrectomy (PPV).Patients and methods: This quasi-experimental trial was carried out in the Department of Ophthalmology Services Hospital Lahore from June 2020 to December 2020. Fifty seven diabetic patients with vitreous hemorrhage were selected who were eligible for PPV. Patients with recurrent hemorrhage were not included. Demographics were recorded and all patients were given intravitreal bevacizumab (1.25 mg/0.05 ml) one week prior to vitrectomy and intra-operative bleeding was noted. Intra-operative bleeding was graded as No, Mild and Severe bleeding.Results: The mean age of patients undergoing PPV was 55.36 ± 4.62 years. There were 35 (61%) males and 22 (39%) females. The mean duration of diabetes was 10.35±1.92 years. Out of 57 eyes, 36 (63.15%) had no bleeding, 11 (19.29%) had mild and 10 (17.54%) had severe intra-operative bleeding.Conclusion: Intravitreal bevacizumab prior to PPV is quite effective in reducing the risk of intra-operative bleeding in patients with vitreous hemorrhage.

Analysis of risk factors for massive intraoperative bleeding in patients with placenta accreta spectrum

BackgroundTo analyze relevant factors for massive postpartum hemorrhage in women with placenta accreta spectrum in order to improve the ability to identify those at risk for intraoperative bleeding and improve outcome.MethodsThis study is a retrospective study and based on data from Hospital electronic medical record. Placenta accreta patients who delivered by cesarean section at Peking University Third Hospital from September 2017 to December 2019 were selected and included. According to the amount of intraoperative bleeding, they were categoried into the massive bleeding group (bleeding volume ≥ 2000 mL, 68 cases) and non-massive bleeding group (bleeding volume < 2000 mL, 99 cases). Univariate analysis and multivariate logistic regression were used to analyze the correlations between related risk factors or ultrasound imaging characteristics and the severity of bleeding during operation.Results(1) There were statistically significant differences in gravidity, parity, number of prior cesarean deliveries and placenta accreta ultrasound scores (P < 0.05) between the two groups of patients.(2) Among the ultrasonographic indicators, the disappearance of the post-placental clear space, the emergence of cross-border blood vessels in the region of subplacental vascularity, interruption or disappearance of the bladder line, and the presence of the cervical blood sinus had the most significant correlation with hemorrhage during PAS (P < 0.05).ConclusionThe presence of cervical blood sinus, interruption or disappearance of bladder line, the disappearance of the post-placental clear space and abnormal subplacental vascularity are independent risk factors for massive hemorrhage during PAS. We should pay more attention to these indicators in prenatal ultrasound examination in order to reduce the intraoperative bleeding and improve maternal outcomes.

The use of intranasal glucocorticosteroids in patients with chronic rhinosinusitis in the preoperative period

Introduction. Chronic rhinosinusitis is a disease that occurs everywhere, characterized by inflammation of the mucous membrane of the paranasal sinuses and nasal cavity. If it is impossible to eliminate the causes of the recurrent disease with medical therapy, the use of surgical treatment help to recover the normal functioning of the ostium, including the ostiomeatal complex to improve ventilation and drainage of the paranasal sinuses and recover nasal breathing to relieve chronic inflammation.Purpose of the study. Assessment of the degree of intraoperative bleeding in patients with chronic rhinosinusitis.Materials and methods. On the basis of the FGBU SPB Research Institute of ENT of the Ministry of Health of the Russian Federation in the period from 2020 to 2021. the study of the effect of local intranasal glucocorticosteroids (INGKS) in the intraoperative period in patients with chronic polypous rhinosinusitis was carried out. The total amount of blood loss during surgery for chronic polypous rhinosinusitis in patients who used mometasone furoate preoperatively and in patients not taking topical hormonal drugs was analyzed.Results. In the study group, the average blood loss per operation was 257 ml, in the control group – 401 ml. In patients who took intranasal glucocorticosteroids during surgery, the intensity of bleeding is less pronounced. Undoubtedly, there are many reasons that affect the intensity of bleeding in general, however, a decrease in the inflammatory response in the nasal cavity and a decrease in inflammatory metabolites have a beneficial effect on the state of the nasal mucosa.Conclusion. The use of intranasal glucocorticosteroids in the preoperative period has a positive effect on reducing the inflammatory process in the nasal cavity, which helps to reduce the intensity of intraoperative bleeding.

A rational approach to the prevention ofthromboembolic complications in the surgical treatment of complicated forms ofcholelithiasis in patients with liver cirrhosis

Background. It is known from scientific sources that a significant proportion of complications of liver cirrhosis is associated with negative impact of this pathology on the coagulation system. According to many scientists, liver cirrhosis in most cases poses a risk of developing both thrombotic and hemorrhagic complications. Objective: to identify a rational approach to the prevention of thromboembolic complications in the surgical treatment of complicated forms of cholelithiasis in patients with cirrhosis. Materials and methods. We retrospectively analyzed the hospital records of 62 patients who were treated for complicated forms of cholelithiasis with verified liver cirrhosis for the period from 2005 to 2018. The distribution of patients by nosology was as follows: acute calculous cholecystitis— 48 patients, Mirizzi syndrome— 7, choledocholithiasis— 7. Results. Based on a comparative analysis of two groups, the risk of intraoperative bleeding in patients with preoperative prophylaxis was higher (3cases— 8.1 %), with a blood loss of more than 400 ml. Hematomas of postoperative wounds were observed in 5 cases in group 1 and in one case in group 2. In the group of preoperative prophylaxis, portal vein thrombosis (n = 1), thrombosis of small branches of the pulmonary artery (n = 1), and deep vein thrombosis of the leg (n = 1) developed. No such complications were observed in the group with postoperative prophylaxis. Conclusions. The decision on the prevention of thromboembolic complications in this category of patients should be balanced and include an assessment of the risks of developing both hemorrhagic disorders and complications associated with thrombosis.

Application of supraomohyoid neck dissection via retroauricular hairline incision in patients with oral cancer

ObjectiveTo explore the application of supraomohyoid neck dissection via retroauricular hairline incision in patients with oral cancer, thereby providing a basis for the surgical treatment of patients with oral cancer in clinical practice. MethodsA total of 68 patients with oral cancer who met the inclusion criteria and exclusion criteria were included in our hospital from August 2018 to June 2020. According to the random number table method, they were divided into the experimental group (34 cases), in which patients underwent supraomohyoid neck dissection via retroauricular hairline incision, and control group (34 cases), in which patients received neck dissection. ResultsThe operation time was significantly longer and the intraoperative bleeding was significantly less in the experimental group compared with those in the control group (both P < 0.05). No significant differences in postoperative drainage, number of detected lymph nodes and length of hospital stay were detected between the two groups. One month after surgery, the scores of pains, muscle strength, range of motion and daily activities were significantly higher in the experimental group than those in the control group (all P < 0.05). Three months after surgery, the scores of pains, muscle strength, range of motion and daily activities were higher compared with those at one month after surgery in both groups, and these scores in the experimental group were higher than those in the control group (all P < 0.05). In addition, the scores of shoulder function, language, deglutition, chew, work, entertainment, activity of daily living, facial features, pain and degree of satisfaction to the scars in the experimental group were significantly higher than those in the control group one month after surgery (all P < 0.05). ConclusionSupraomohyoid neck dissection via retroauricular hairline incision can reduce the amount of intraoperative bleeding in patients with oral cancer, is beneficial to the recovery of shoulder joint function, improves the patient's quality of life and the degree of satisfaction to the scars, reduces the occurrence of related complications. It has relatively high safety and is worthy of clinical application and promotion.

Assessment of laboratory tests and intraoperative bleeding in patients with liver cirrhosis undergoing tooth extractions

The objective of this study was to quantify intraoperative bleeding in patients with cirrhosis and correlate it with clinical characteristics and laboratory coagulation tests. A case-control study was carried out with 74 patients with cirrhosis who were submitted to preoperative coagulation tests (complete blood count, platelet count, prothrombin time/international normalized ratio, thrombin time, activated partial thrombin time, platelet aggregation, fibrinogen, protein C, protein S, antithrombin, and von Willebrand factor level and activity). The levels of nitrogen compounds that can affect the platelet function were determined in saliva and blood by using automated enzymatic-colorimetric assays. Patients with cirrhosis had changes in almost all coagulation tests. The average volumes of intraoperative bleeding and blood lost per minute in the study group (5.36 mL/min and 0.19 mL/min, respectively) were greater than those in the control group (3.05 mL/min and 0.11 mL/min, respectively; P < .05). In the control group, ascites (P=.012) and presence of periapical lesion (0.034) were positively correlated with bleeding (mL/min). With regard to coagulation tests and nitrogen compounds, only a positively moderate correlation with the platelet aggregation test was observed. No patients had hemorrhagic events and it was not possible to correlate a greater amount of bleeding with coagulation tests or nitrogen compounds in the study group.

Placenta previa with posterior extrauterine adhesion: clinical features and management practice

BackgroundA diagnostic sign on magnetic resonance imaging, suggestive of posterior extrauterine adhesion (PEUA), was identified in patients with placenta previa. However, the clinical features or surgical outcomes of patients with placenta previa and PEUA are unclear. Our study aimed to investigate the clinical characteristics of placenta previa with PEUA and determine whether an altered management strategy improved surgical outcomes.MethodsThis single institution retrospective study examined patients with placenta previa who underwent cesarean delivery between 2014 and 2019. In June 2017, we recognized that PEUA was associated with increased intraoperative bleeding; thus, we altered the management of patients with placenta previa and PEUA. To assess the relationship between changes in practice and surgical outcomes, a quasi-experimental method was used to examine the difference-in-difference before (pre group) and after (post group) the changes. Surgical management was modified as follows: (i) minimization of uterine exteriorization and adhesion detachment during cesarean delivery and (ii) use of Nelaton catheters for guiding cervical passage during Bakri balloon insertion. To account for patient characteristics, propensity score matching and multivariate regression analyses were performed.ResultsThe study cohort (n = 141) comprised of 24 patients with placenta previa and PEUA (PEUA group) and 117 non-PEUA patients (control group). The PEUA patients were further categorized into the pre (n = 12) and post groups (n = 12) based on the changes in surgical management. Total placenta previa and posterior placentas were more likely in the PEUA group than in the control group (66.7% versus 42.7% [P = 0.04] and 95.8% versus 63.2% [P < 0.01], respectively). After propensity score matching (n = 72), intraoperative blood loss was significantly higher in the PEUA group (n = 24) than in the control group (n = 48) (1515 mL versus 870 mL, P < 0.01). Multivariate regression analysis revealed that PEUA was a significant risk factor for intraoperative bleeding before changes were implemented in practice (t = 2.46, P = 0.02). Intraoperative blood loss in the post group was successfully reduced, as opposed to in the pre group (1180 mL versus 1827 mL, P = 0.04).ConclusionsPEUA was associated with total placenta previa, posterior placenta, and increased intraoperative bleeding in patients with placenta previa. Our altered management could reduce the intraoperative blood loss.

Effects of perioperative magnesium sulfate infusion on intraoperative blood loss and postoperative analgesia in patients undergoing posterior lumbar spinal fusion surgery: A randomized controlled trial

ObjectiveMany studies have suggested the anti-nociceptive role for magnesium either as an adjunct for postoperative pain. Although several studies have been carried out to evaluate the anti-nociceptive effect of magnesium, there is still considerable uncertainty. Patients and MethodsEighty patients who underwent posterior spinal fusion were randomly divided into two groups (magnesium and saline). Changes in cell count, magnesium concentration and coagulation status were assessed one hour after operation at both group and compared to baseline. At recovery room, their pain score was assessed according to 10 points visual analogue scale (VAS). Morphine consumption was evaluated at regular times after the surgery by patient controlled analgesia (PCA) device. ResultsVAS scores were significantly lower in the magnesium group. Cumulative PCA morphine consumption after the surgery was significantly lower in the magnesium group. Pre and postoperative values for haemoglobin, platelet count, Prothrombin Time (PT), fibrinogen were not significantly different. There was a significant increase in activated Partial Thromboplastin Time (aPTT), International Normalized Ratio (INR), and bleeding time (BT), one hour after the operation in the magnesium group but intraoperative blood loss was similar in both groups. ConclusionsPerioperative magnesium sulfate infusion improves the postoperative analgesia, decreases the amount of morphine consumption after the operation and does not change the intraoperative bleeding in patients undergoing posterior spinal fusion surgery.
