Effectiveness of an ERAS-based exercise-nutrition management model in enhancing postoperative recovery for thoracoscopic radical resection of lung cancer: A randomized controlled trial.

BACKGROUND: To analyze the effect of an exercise-nutrition management model based on the Enhanced Recovery After Surgery (ERAS) concept on patients undergoing thoracoscopic radical surgery for lung cancer. METHODS: From June 2019 to December 2022, 85 lung cancer patients who underwent thoracoscopic radical lung cancer surgery were randomly divided into 2 groups. The control group, consisting of 42 patients, received routine nursing care during the perioperative period. The study group, comprising 43 patients, implemented an exercise-nutrition management model based on the ERAS concept during the perioperative period. We compared general data, perioperative indicators, compliance, and complications between the 2 groups. Additionally, we assessed the nutritional status using the patient-generated subjective global assessment (PG-SGA), albumin (ALB), prealbumin (PA), and hemoglobin (Hb), as well as lung function, including forced expiratory volume in the first second (FEV1) and maximum voluntary ventilation (MVV), in the patient population following the Piper intervention. RESULTS: In the study group, the times to first defecation and getting out of bed, the duration of thoracic drainage tube indwelling, and the length of hospital stay were shorter than those in the control group. The VAS scores on the 2nd and 3rd postoperative days were lower in the study group than in the control group (P < .05). Medication compliance was higher in the study group compared to the control group (P < .05). Post-intervention, the PG-SGA scores in the study group were lower, while PA, ALB, and Hb levels were higher than those in the control group (P < .05). The MVV, FEV1, and FVC values were higher in the study group than in the control group after the intervention (P < .05). The PFS and mMRC scores were lower in the study group compared to the control group after the intervention, and the QLQ-C30 scores were higher (P < .05). The incidence of complications was 6.98% in the study group, which was not significantly different from 11.90% in the control group (P > .05). CONCLUSION: The exercise-nutrition management model, based on the ERAS concept, exhibits significant perioperative effects in patients undergoing thoracoscopic radical resection of lung cancer, improving their nutritional status and reducing complications.

Effect of perioperative "Internet + rehabilitation guidance" based on IKAP theory on short-term prognosis of patients with esophageal cancer.

OBJECTIVE: The aim of the study was to investigate the "Internet + rehabilitation guidance" under the theory of Information-Knowledge-Attitude-Practice (IKAP) in patients with esophageal cancer during the perioperative period and to analyze the influence on the short-term prognosis of patients with esophageal cancer. PATIENTS AND METHODS: From April 2022 to February 2023, 118 patients who underwent radical esophagectomy in the First Hospital of Huai'an Affiliated Hospital of Nanjing Medical University were enrolled using the convenience sampling method. They were divided into the IKAP group (59 cases) and the Control Group (Group C) (59 cases), according to the random number table method. The conventional intervention was performed during the perioperative period, and the IKAP group was also given "Internet + rehabilitation guidance" based on IKAP theory. The first postoperative defecation time, exhaust time, feeding time, discharge time, and postoperative complication rate of the two groups were compared. Meanwhile, blood samples were collected before surgery and 1, 3, 7, and 30 days after surgery (at outpatient review) for the detection of inflammatory factor indexes and nutritional indexes. RESULTS: Patients within the IKAP group showed a shorter first postoperative exhaust and defecation time, eating time, and hospital compared to the control group (p<0.05). Before surgery, there was no significant difference in serum inflammatory factors and nutritional indexes between the two groups (p>0.05). Comparing the levels of serum inflammatory factors in the two groups after surgery, the levels of CRP and IL-6 in the IKAP group were lower than those in the control group on days 1, 3, and 7 after surgery. After 30 days, the serum CRP level was found to be lower than the control group, but no statistical difference with the control level of serum IL-6 (p<0.05) was found. Compared with the serum nutritional index levels in the two groups: 1 d after surgery, the serum HGB, PA, and TRF levels were not different (p>0.05). The serum ALB level in the IKAP group was higher than that in the control group (p<0.05). Postoperative 3 d, 7 d, the serum levels of HGB, ALB, PA, and TRF in the IKAP group were higher than those in the control group (p<0.05). After 30 d, there was no statistical difference in serum HGB levels between the two groups (p<0.05); Serum ALB, PA, and TRF levels in the IKAP group were higher than those in the control group (p<0.05). From preoperative to 30 days after surgery, serum CRP and IL-6 levels in 2 groups were first increased and then decreased, while serum HGB, ALB, PA, and TRF levels were first decreased and then increased. After surgery, the IKAP group showed a greater incidence of complications in patients than in controls (p<0.05). CONCLUSIONS: In patients with esophageal cancer, perioperative "Internet + rehabilitation guidance" based on IKAP theory can effectively shorten the postoperative gastrointestinal function recovery time and rapidly reduce the inflammatory response, improving the nutritional status of the body, thereby reducing the risk of short-term postoperative complications.

Perioperative considerations for robotic-assisted thoracic surgery.

Robotic-assisted thoracic surgery is being offered to more patients because it has a number of potential benefits. Awareness of the challenges that this type of surgery brings will allow teams to manage these patients safely in the perioperative period.

Safety of antiplatelet therapy during the perioperative period of revascularization surgery for moyamoya disease patients with ischemic onset.

For patients with moyamoya disease, antiplatelet agents are often used during the perioperative periods of revascularization surgeries to prevent ischemic events. However, antiplatelet therapy is associated with the risk of hemorrhagic complications. Further, the influence of antiplatelet therapy on perioperative ischemic or hemorrhagic complications has not been investigated. This study aimed to determine the impact of antiplatelet agents on adult moyamoya disease patients with ischemic onset during the perioperative period. From January 2016 to December 2020, 183 consecutive combined (direct and indirect) revascularization surgeries for moyamoya disease patients were performed. Among these surgeries, 96 consecutive combined revascularization surgeries for adult moyamoya disease patients with ischemic onset were analyzed and perioperative ischemic and hemorrhagic complications were reviewed. Antiplatelet agents were continued during the perioperative period including on the day of surgery and the day after the surgery. Among 96 surgeries, no hemorrhagic complications occurred postoperatively. Infarction occurred in five cases (5.2%). Among the five cases, neurological deficits persisted in two cases and improved in three. The median value of bleeding volume was 112.5 mL (interquartile range, 80.0 - 200.0). Twenty-five cases (26.0%) needed blood transfusion. The modified Rankin Scale score deteriorated in two cases due to cerebral infarction. The incidence of hemorrhagic and ischemic complications after combined revascularization surgery in patients with ischemic moyamoya disease under antiplatelet therapy was low, indicating the safety of continued antiplatelet therapy.

Recombinant porcine factor VIII in patients with congenital haemophilia A with inhibitors undergoing surgery: Phase 3, single-arm, open-label study.

INTRODUCTION: Recombinant porcine factor VIII (rpFVIII; susoctocog alfa) is predicted to provide functional FVIII activity in patients with congenital haemophilia A with inhibitors (CHAWI). AIMS: To evaluate the efficacy and safety of rpFVIII in patients with CHAWI undergoing invasive procedures. METHODS: This phase 3, multicentre, single-arm, open-label study (NCT02895945) enrolled males aged 12-75 years with severe/moderately severe CHAWI who required surgical/invasive procedures. Patients received a loading dose of rpFVIII 1-2 h before surgery. The primary outcome was the proportion of all procedures with a 'good' or 'excellent' response (treatment success) on the global haemostatic efficacy assessment score. RESULTS: Of the eight dosed patients, five completed the study. Six of seven surgeries (85.7%; 95% confidence interval, 42.1-99.6) achieved treatment success; five were rated 'excellent', one was rated 'good'. Seven surgery-related bleeding episodes occurred in three patients during the study, with none requiring additional surgical intervention. Overall, six of eight patients experienced 17 treatment-emergent adverse events. Three patients developed de novo inhibitors to rpFVIII. Five patients reported anamnestic reactions, three to both human (h) FVIII (i.e., alloantibodies to exogenous FVIII detected with anti-hFVIII assays) and rpFVIII, and two to hFVIII only. Four serious adverse events were considered related to rpFVIII (three anti-rpFVIII antibody positive; one anamnestic reaction to hFVIII and rpFVIII). CONCLUSION: Good haemostasis was achieved with rpFVIII during the immediate perioperative period. The study was terminated early because the study sponsor and health authorities determined that the risk of anamnestic reactions outweighs the benefits in this study population.

Remifentanil improves left ventricular diastolic parameters in patients with impaired diastolic function: a prospective clinical study.

BACKGROUND: Left ventricular diastolic dysfunction has a significant impact on perioperative morbidity and mortality, and its incidence is high in elderly individuals. Anesthetic agents may impair diastolic function, which may increase the incidence of perioperative complications. The aim of this prospective, clinical, phase 4 study was to investigate the effects of remifentanil on left ventricle (LV) diastolic function in patients with diastolic dysfunction. The study was performed on 30 spontaneously breathing subjects (aged 60-80 years) with diastolic dysfunction. METHODS: Thirty patients (aged 60-80 years) with diastolic dysfunction scheduled for surgery were recruited between November 2019 and March 2023. Left ventricle function was evaluated once the intravenous remifentanil infusion reached a target-controlled concentration of 2 ng/ml with transthoracic echocardiography. Analysis of systolic function focused on left ventricular ejection fraction and mean mitral annular S velocity (Sm), whereas diastolic function focused on changes in transmitral peak flow (E), E/A, mitral septal and lateral e' waves, E/e' ratios and left atrial volume index following remifentanil infusion. RESULTS: Diastolic function measures of LV (mitral E/e', septal and lateral e' waves) statistically significantly improved (E/e' from 10.6 ± 2.9 cm.sn- 1 to 9.5 ± 2.2 cm.sn- 1; p = 0.006) following remifentanil infusion. Left atrial volume index decreased following remifentanil infusion without statistical significance (from 55 ± 14.4 ml.cm- 2 to 51.6 ± 13.3 ml.cm- 2; p = 0.1). Systolic function (ejection fraction and Sm) did not change following remifentanil infusion. CONCLUSIONS: Remifentanil improves left ventricular diastolic parameters in patients with preexisting diastolic dysfunction. Our study suggests that remifentanil at a plasma concentration of 2 ng.ml- 1 might be used safely in patients with left ventricular diastolic dysfunction.

Application on perioperative ERAS concept in elderly lung cancer patients undergoing surgery.

Investigating the applying effects of the enhanced recovery after surgery (ERAS) in the perioperative period of elderly lung cancer patients undergoing the surgery. We randomly selected 98 elderly patients with lung cancer who were admitted to our hospital and underwent surgery from January 2022 to September 2023 as study subjects. The control group received conventional care during the perioperative period, and the intervention group received ERAS-guided care measures. The differences in perioperative-related indices, pulmonary function, pain level, inflammatory factors, and postoperative complication rates between these 2 groups were compared. The postoperative extubation time, the activity time since getting out of bad and hospital stay were lower in the observation group than those in the control group (P < .05). At 3 days postoperatively, the FEV1, forced vital capacity and maximum ventilation volume of these 2 groups were lower than those of their same groups before surgery, and those of the observation group were higher than those of the control group (P < .05). At 3 days postoperatively, the numerical rating scale in both groups were lower than those of their same groups at 6 hours postoperatively, and the numerical rating scale of the observation group was lower than that of the control group (P < .05). At 3 days postoperatively, tumor necrosis factor-α, IL-6, and CRP in both groups were higher than those in their same groups before surgery, and those of the observation group was lower than those of the control group (P < .05). The incidence of postoperative complications in the observation group was lower than that in the control group (P < .05). ERAS applied in the perioperative period of elderly lung cancer patients undergoing surgery can shorten the hospital stay, promote the postoperative recovery on pulmonary function, alleviate inflammation, and reduce the risk of postoperative complications.

Development of an Evaluation System for the Prophylactic Use of Antimicrobial Drugs in the Perioperative Period of Class I Surgical Incisions in Neurosurgery.

BACKGROUND: This study aimed to establish a precise preoperative high-risk factor scoring system and algorithm for antibiotic prophylaxis decision-making, provide guidance for the judicious use of AMP, refine interventions, and ensure the appropriate application of AMP for class I incisions in neurosurgery. METHODS: According to PRISMA guidelines, literature searches, study selection, methodology development, and quality appraisal were performed. The quality of evidence across the study population was assessed using the Newcastle-Ottawa Scale. A two-round Delphi expert consultation method involved 15 experts from leading tertiary hospitals in China. Establishing an algorithm of SOPs for perioperative antimicrobial prophylaxis in Class I neurosurgical incisions. RESULTS: Thirteen studies, encompassing 11,936 patients undergoing clean neurosurgical procedures, were included. 791 patients experienced SSI, resulting in an average incidence of 6.62%. Identified risk factors significantly associated with an increased incidence of postoperative SSI (P < 0.05) included emergency surgery, preoperative hospitalization ≥7 days, intraoperative blood loss ≥300 mL, operation time ≥4 hours, diabetes mellitus, cerebrospinal fluid leakage, and repeat surgery. Sensitivity analysis demonstrated robust results for emergency surgery, intraoperative blood loss ≥300 mL, operation time ≥4 hours, cerebrospinal fluid leakage, and repeat surgery. Established a risk assessment system for Class I neurosurgical incisions by the Delphi method. Additionally, we have formulated an algorithm of SOPs for perioperative antimicrobial prophylaxis in Class I neurosurgical incisions. CONCLUSIONS: The established index for AMP utilization and SOPs in the preoperative period of class I neurosurgical incisions proves valuable, contributing to improved patient outcomes in neurosurgical procedures.

Cases of pleural effusion possibly due to clinical pleuroperitoneal communication in the perioperative period of emergency gynecologic surgery: Case series and literature review.

Pleuroperitoneal communication poses a respiratory failure risk due to pleural fluid accumulation with thoracic migration of ascites. Here, we discuss the following cases: Case 1: A woman was diagnosed with a ruptured ovarian tumor with right pleural fluid and ascites, without respiratory failure. Ovarian cystectomy was performed with inadequate removal of ascites. Postoperatively, respiratory failure occurred, and thoracentesis detected pleural fluid resembling ascites. Case 2: A woman was diagnosed with a ruptured ectopic pregnancy with right pleural fluid and ascites without respiratory failure. A diagnosis of clinical pleuroperitoneal communication was considered based on computed tomography findings. During laparoscopic salpingectomy, high-pressure ventilation was performed to push the pleural fluid back into the abdominal cavity; a negative-pressure drain was inserted, and the ascites was completely removed. Postoperative radiography revealed the absence of pleural fluid. Therefore, a preoperative diagnosis of clinical pleuroperitoneal communication and appropriate intraoperative techniques can prevent postoperative respiratory failure.

Construction of a predictive model for blood transfusion in patients undergoing total hip arthroplasty and identification of clinical heterogeneity.

A precise forecast of the need for blood transfusions (BT) in patients undergoing total hip arthroplasty (THA) is a crucial step toward the implementation of precision medicine. To achieve this goal, we utilized supervised machine learning (SML) techniques to establish a predictive model for BT requirements in THA patients. Additionally, we employed unsupervised machine learning (UML) approaches to identify clinical heterogeneity among these patients. In this study, we recruited 224 patients undergoing THA. To identify factors predictive of BT during the perioperative period of THA, we employed LASSO regression and the random forest (RF) algorithm as part of supervised machine learning (SML). Using logistic regression, we developed a predictive model for BT in THA patients. Furthermore, we utilized unsupervised machine learning (UML) techniques to cluster THA patients who required BT based on similar clinical features. The resulting clusters were subsequently visualized and validated. We constructed a predictive model for THA patients who required BT based on six predictive factors: Age, Body Mass Index (BMI), Hemoglobin (HGB), Platelet (PLT), Bleeding Volume, and Urine Volume. Before surgery, 1 h after surgery, 1 day after surgery, and 1 week after surgery, significant differences were observed in HGB and PLT levels between patients who received BT and those who did not. The predictive model achieved an AUC of 0.899. Employing UML, we identified two distinct clusters with significantly heterogeneous clinical characteristics. Age, BMI, PLT, HGB, bleeding volume, and urine volume were found to be independent predictors of BT requirement in THA patients. The predictive model incorporating these six predictors demonstrated excellent predictive performance. Furthermore, employing UML enabled us to classify a heterogeneous cohort of THA patients who received BT in a meaningful and interpretable manner.

Meta-synthesis of qualitative studies on patient perceptions and requirements during the perioperative period of robotic surgery.

This research undertakes a comprehensive evaluation and amalgamation of patient experiences and requirements during the perioperative period of robot-assisted surgery (RS), with the goal of enriching clinical practice with patient-centered insights. A meta-synthesis was performed and reported according to the preferred reporting Items for systematic reviews and meta-analyses and the enhancing transparency in reporting the synthesis of qualitative research statement. A rigorous literature search was conducted across multiple Chinese and English databases, namely PubMed, CINAHL (EBSCO), Embase, Web of Science, Scopus, China Biomedical Literature Database (CBLD), China National Knowledge Infrastructure (CNKI), Wanfang Data, and VIP Information. This study incorporated ten qualitative studies, the outcomes were classified into three overarching themes: personalized patient requirements related to RS; the psychological and physiological experiences of patients; and the divergent perceptions of male and female patients regarding RS. Greater emphasis needs to be placed on patient comprehension of RS, augmenting focus on patient psychological experiences, recognizing unique patient needs at various stages of RS, and providing patients with specialized knowledge and technical support.

Perioperative hypersensitivity in children: A prospective multidisciplinary study.

BACKGROUND: There are few studies of perioperative hypersensitivity reactions in children. The diagnosis of perioperative hypersensitivity reactions may be under estimated because it is difficult to recognize the reactions. Anaphylaxis may go unnoticed because of patient unconsciousness. Urticaria may be missed due to sterile drapes. The aim of this study was to prospectively evaluate perioperative hypersensitivity reactions. METHODS: In this prospective study, patients with suspected perioperative hypersensitivity reactions aged 0-18 years who underwent surgery at the Department of Pediatric Surgery, Cerrahpasa Faculty of Medicine, between 2019 and 2021 were investigated. Suspected reactions in the perioperative period were graded according to the Ring and Messmer scale. Patients with suspected reactions were examined 4-6 weeks after the reaction. If necessary, specific IgE and basophil activation tests were performed. Reactions of grades III-IV were considered anaphylaxis. If one test modality was strongly positive and there was a relevant time point or repeated allergic reactions, or at least two test modalities were positive, hypersensitivity was confirmed. In all patients, serum tryptase levels were analyzed at the time of the reaction, 2 h after the reaction, and 4-6 weeks after the reaction as part of the allergic evaluation. RESULTS: A total of 29 patients (8 female, 21 male) suspected of having an intraoperative reaction during the study were included in the analysis. Perioperative hypersensitivity reactions were noted in 1 patient. The incidence of perioperative hypersensitivity reactions was reported to be 0.03% (n = 1/2861). While anaphylaxis was confirmed in 1 patient, 5 patients were considered possible anaphylaxis cases. CONCLUSION: Perioperative hypersensitivity reactions can be life-threatening and may recur with further administration. Collaboration between pediatric surgeons, anesthesiologists, and allergists can prevent further reactions. All suspected cases should be evaluated by an experienced allergist soon after the initial reaction.

Anaesthetic management of a child with Fontan heart undergoing laparoscopic cholecystectomy: A case report.

The Fontan procedure is a staged palliative surgery performed in children with congenital univentricular heart defects. These individuals are predisposed to a variety of issues due to their altered physiology. Through this article, we would like to describe the evaluation and anaesthetic management of a 14-year-old boy with Fontan circulation who underwent an uneventful laparoscopic cholecystectomy. The key to successful management was a multidisciplinary approach throughout the perioperative period as these patients pose a unique set of problems.

Blood Product Transfusions for Children in the Perioperative Period and for Critically Ill Children.

BACKGROUND: Approximately 1% to 2% of all hospitalized children receive a transfusion of blood products, in Germany as in other countries. High-quality scientific evidence on transfusions in children is scarce. The available evidence is discussed in this review. METHODS: This review is based on publications on blood product transfusions in children that were retrieved by a literature search, including clinical studies, international guideline recommendations, the recommendations of the German cross-sectional guideline, and results of other recent, relevant publications. RESULTS: A restrictive transfusion strategy is recommended for all children, including those who are critically ill. Randomized controlled trials have shown that a restrictive strategy for erythrocyte concentrate transfusion in the intensive care unit is safe for children, including neonates. No robust data are available to enable the definition of a suitable threshold for the intraoperative administration of red blood cell concentrates in children undergoing extracardiac surgery. On the basis of studies from pediatric intensive care units, transfusions for hemodynamically stable children with a hemoglobin concentration of more than 7 g/dL are recommended only in exceptional cases. Therapeutic plasma is not recommended as volume replacement, except in massive transfusion. Platelet concentrate transfusions are indicated in case of active hemorrhage, and only rarely for prophylaxis. CONCLUSION: There is a broad lack of evidence from randomized controlled trials concerning the indications for transfusions in children. A restrictive transfusion strategy, which has been found safe in the intensive-care setting, is favored by the guidelines in the perioperative setting as well. Further studies are needed to evaluate transfusion triggers and indications for all types of blood products, especially therapeutic plasma. Until more evidence is available, physicians should be aware of what the current evidence supports, and blood products should be given restrictively, and not prophylactically.

[Low Output Syndrome:Points to Consider for Intraoperative Myocardial Protection and Treatment Methods].

Low cardiac output syndrome (LOS) is a condition that causes low perfusion and perfusion failure of the entire body's tissues due to a decline in heart contractile strength, posing a significant challenge in cardiothoracic surgical perioperative management. Appropriate myocardial protection is crucial to prevent ischemia-reperfusion injury during open-heart surgery and prevent LOS. The integrated myocardial protection method, proposed by Buckberg et al., is one technique employed for this purpose. In the treatment of LOS, interventions are made in the parameters of stroke volume and heart rate, structural abnormalities are excluded and dealt with, and mechanical assistance is utilized when necessary. With the aging and increasing severity of surgical patients, the risk of postoperative LOS is on the rise. Therefore, the application of appropriate myocardial protection and treatment methods leads to improved prognosis. It's worth noting that ensuring optimal myocardial protection during surgery and the correct application of medication and devices for intervention can significantly improve patient outcomes. With the rise in high-risk surgical cases due to aging and an increase in severe conditions, the importance of these interventions cannot be overstated.

Coagulation parameters correlate to venous thromboembolism occurrence during the perioperative period in patients with spinal fractures.

BACKGROUND: Venous thromboembolism (VTE) is one of the leading causes of mortality in hospitalized patients. However, whether the coagulation-related parameters of the hospitalized patients could be used to predict the occurrence of VTE in patients with spinal injury surgery remained unclear. METHOD: The patients with spinal fractures who met the inclusion and exclusion criteria were enrolled to be analyzed using a retrospective analysis approach. The association of risk factors of enrolled patients and operations to VTE occurrence were analyzed. The activated partial thromboplastin time, prothrombin time, thrombin time, D-dimer (D-D), fibrinogen (FIB) and fibrinogen degradation products (FDP) were detected. ROC and HR analysis were applied to evaluate the correlation of coagulation-related parameters and other parameters to VTE occurrence. RESULT: The indicators of D-D, FIB and FDP were significantly elevated in VTE patients compared to non-VTE patients. The multivariate analysis of OR showed that six risk factors, including age ≥ 60, spinal cord injury, postoperative bedtime over 5 days, plasma D-dimer ≥ 0.54 mg/L, plasma fibrinogen ≥ 3.75 g/L and plasma FDP ≥ 5.19 mg/L, were positively correlated to VTE. CONCLUSION: The six risk factors, including D-D, FIB, FDP, age ≥ 60, spinal cord injury, and postoperative bedtime over 5 days, could be used to predict the occurrence of VTE.

Assessment of dyspnea, ADL, and QOL in the perioperative period in lung cancer patients treated with minimally invasive surgery.

OBJECTIVE: Patients with lung cancer generally undergo minimally invasive surgery, such as video-assisted thoracoscopic surgery (VATS). This study examined the changes in health conditions and symptoms of patients with lung cancer using the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC QLQ) C-30 questionnaires after surgery. METHODS: This was a longitudinal descriptive study. One hundred and three patients with lung cancer who underwent lung resection at Tokushima University Hospital between 2012 and 2021 were eligible. They completed EORTC QLQ-C30, QLQ-LC13, the Cancer Dyspnea scale (CDS), and pulmonary-ADL (P-ADL) before and 1, 3, and 6 months after surgery. RESULTS: Regarding functional scale scores, impairments in physical and role functions persisted for 6 months after surgery. In symptom scale scores, fatigue, pain, dyspnea, and appetite loss continued for 6 months after surgery. In CDS, sense of effort, discomfort, and total dyspnea scale scores were elevated for 6 months after surgery. In P-ADL, most ADL were impaired 1 month after surgery, but recovered by 3 months. The dyspnea index of ADL was lower for 6 months after surgery. CONCLUSIONS: Impairments in health conditions and symptoms persisted for 6 months after surgery despite its minimally invasive nature.

[The predictive values of platelet mitochondrial mass and quantity during the perioperative period in elderly patients on the occurrence of postoperative delirium].

Objective: To investigate the changes of platelet mitochondrial mass and quantity during perioperative period in elderly patients, and assess their predictive values on the occurrence of postoperative delirium (POD). Methods: In this prospective study, 162 elderly patients scheduled for abdominal surgery under general anesthesia were enrolled from November 2021 to January 2022 in Nanjing Drum Tower Hospital Affiliated to Nanjing University Medical School. Among them, 20 patients [10 males, 10 females, aged (71.4±6.8) years] developed POD within 3 days after surgery (POD group), and another 20 patients[12 males, 8 females, aged (67.7±5.3) years] who did not develope POD were selected as controls (control group) using propensity score matching method. Blood samples were collected preoperatively, at the end of surgery and on the first postoperative day. Platelets were extracted and mitochondrial mass was detected with flow cytometry. Transmission electron microscopy was used to determine mitochondrial quantity. The receiver operating characteristic (ROC) curve was drawn to analyze the value of mitochondrial mass and quantity in predicting the occurrence of POD. Results: The mean fluorescence intensities of platelet mitochondrial mass were 193±46, 236±61, 264±53 preoperatively, at the end of surgery and on the first postoperative day in the POD group, respectively. The corresponding values were 209±61, 191±67 and 201±56 in the control group. The platelet mitochondrial mass of patients in the POD group was significantly increased on the first postoperative day compared to preoperative levels (P<0.001). In contrast, there was no significant difference in the control group (P=0.410). Patients in the POD group had higher platelet mitochondrial mass than patients in the control group on the first postoperative day(P=0.002). Meanwhile, platelets from patients in the POD group showed significantly higher number of mitochondria than platelets from patients in the control group [3 (2, 4) vs 2 (1, 2), P<0.001]. According to the ROC curve of platelet on the first postoperative day, at a mitochondrial mass cut-off value of>275.35, the sensitivity, specificity and area under the ROC curve to detect the occurrence of POD were 55%, 90% and 0.800 (95%CI: 0.666-0.934, P<0.001). At a mitochondrial quantity cut-off value of>2, the sensitivity, specificity and area under the ROC curve to detect the occurrence of POD were 53%, 78% and 0.680 (95%CI: 0.584-0.776, P<0.001). Conclusions: Patients who developed POD show higher platelet mitochondrial mass after surgery compared to preoperative levels. The mitochondrial mass of platelets on the first postoperative day has good predictive value on the occurrence of POD.

[Use of tamsulosin for a prevention of acute urinary retention in the perioperative period in patients undergoing to surgical procedures].

The perioperative management of patients involves multiple aspects. Acute urinary retention (AUR) is one of the possible postoperative complications. Alpha-adrenoblockers are commonly used for treatment and prevention of AUR. Tamsulosin is the most often prescribed drug; there are a lot of studies devoted to its use in different patient subgroups. The aim of our study was to evaluate the efficiency of perioperative use of tamsulosin for the prevention of postoperative AUR. A literature review from January 2013 to June 2023 in Scopus and PubMed databases was carried out. According to the results, tamsulosin results in a significant reduction in the risk of postoperative AUR. A personalized approach allows to overcome difficulties in the perioperative management of patients and significantly improve their quality of life/satisfaction from treatment.
