Background: Conventional single indicators have low sensitivity and specificity for predicting weaning from mechanical ventilation in pediatric patients, necessitating the establishment of a combined prediction model for predicting weaning outcomes.Objectives: To explore the combined predictive value of PaO₂/FiO₂ Ratio (P/F ratio), diaphragm excursion-rapid shallow breathing index (DE-RSBI), diaphragm thickening fraction-rapid shallow breathing index (DTF-RSBI), and Pediatric Critical Illness Score (PCIS) in weaning from mechanical ventilation in pediatric patients.Methods: Sixty critically ill pneumonia pediatric patients requiring mechanical ventilation treatment from July 2022 to June 2023 at the Second Affiliated Hospital of Jiaxing University were selected. They all underwent a spontaneous breathing trial (SBT) and were divided into the weaning success group (42 cases) and weaning failure group (18 cases) based on the weaning outcome. Parameters including total duration of illness, mechanical ventilation duration, heart rate (HR), P/F ratio, diaphragm excursion (DE), DE-RSBI, diaphragm thickening fraction (DTF), DTF-RSBI, and PCIS were included in univariate and multivariate logistic regression analyses to determine independent factors affecting pediatric weaning success. Receiver operating characteristic (ROC) curves were plotted to evaluate the predictive value of P/F ratio, DE-RSBI, DTF-RSBI, PCIS alone or in combination for weaning success.Results: Comparing P/F ratio, DE, DE-RSBI, DTF, DTF-RSBI and PCIS, there were statistically significant differences (P < 0.05). Through collinearity analysis and binary logistic regression analysis,P/F ratio [OR = 0.777, 95% CI (0.641,0.941)], DE-RSBI [OR = 1.694, 95% CI (1.172, 2.447)], DTF-RSBI [OR = 1.057, 95% CI (1.002, 1.114)], and PCIS [OR = 0.661, 95% CI (0.445, 0.982)] were identified as independent factors affecting successful weaning(P < 0.05).The regression equation was: LogitP = 73.299–0.253 P/F ratio + 0.525DE-RSBI + 0.055DTF-RSBI-0.43PCIS.The sensitivity of the combined indicator Logit(P) in predicting successful weaning from mechanical ventilation in pediatric patients was 88.9%, with a specificity of 95.2% (optimal cutoff value of 0.511), and the area under the ROC curve (AUC) was 0.960 [95% CI (0.915, 1.000)]. The AUC of the combined prediction model for predicting pediatric weaning was greater than that of P/F ratio, DE-RSBI, DTF-RSBI and PCIS alone (Z values = 9.129, 2.061, 2.075, 8.326, P < 0.05).Conclusions: In mechanically ventilated pediatric patients, the combined prediction model has better predictive value for weaning success compared to using P/F ratio, DE-RSBI, DTF-RSBI, or PCIS alone.

Maintaining normothermia during the perioperative period is crucial for preventing complications, such as surgical site infections, prolonged hospital stays, and adverse cardiovascular events. This study aimed to elucidate methods of perioperative temperature management by integrating Western and traditional Chinese medicine (TCM) approaches. By combining advanced techniques of Western medicine with holistic and preventative practices of TCM, we aimed to provide a comprehensive strategy for effective perioperative thermal regulation. And a comprehensive literature review was conducted to analyze the causes of perioperative hypothermia and methods of perioperative temperature management from both Western and traditional Chinese medicine (TCM) perspectives. Special emphasis was placed on evaluating the underlying factors contributing to perioperative hypothermia, as well as the effectiveness, selection criteria, indications, contraindications, adverse reactions, and potential complications associated with various temperature management techniques. Effective prevention and management strategies include preoperative risk assessment, physical warming measures, environmental temperature control, pharmacological interventions, perioperative temperature monitoring, comprehensive warming protocols, and postoperative warming and monitoring. Integrating traditional Chinese medicine provides additional methods to enhance overall effectiveness and patient outcomes. By combining these approaches, healthcare providers can significantly reduce the incidence of inadvertent perioperative hypothermia (IPH) and its associated complications, improving patient safety and recovery. For IPH, a complex and challenging medical condition, both traditional Chinese medicine and Western medicine have established their own theoretical bases and developed corresponding prevention and treatment methods. However, it is important to note that although each of these methods has unique value and potential, they also have specific indications and unavoidable limitations. Therefore, by integrating and combining the complementary strengths and resources of traditional Chinese medicine and Western medicine, we can achieve a more comprehensive and effective prevention of IPH, ultimately improving the health and well-being of those affected.

Neuropathic pain (NP) affects approximately 6.9–10% of the world’s population and necessitates the development of novel treatments. Mitochondria are essential in the regulation of cell death. Neuroimmune mechanisms are implicated in various forms of cell death associated with NP. However, the specific involvement of mitochondrial dysfunction and disulfidptosis in NP remains uncertain. Further research is required to gain a better understanding of their combined contribution. Our comprehensive study employs a variety of bioinformatic analysis methods, including differential gene analysis, weighted gene co-expression network analysis, machine learning, functional enrichment analysis, immune infiltration, sub-cluster analysis, single-cell dimensionality reduction and cell-cell communication to gain insight into the molecular mechanisms behind these processes. Our study rationally defines a list of key gene sets for mitochondrial dysfunction and disulfidptosis. 6 hub mitochondrial genes and 3 disulfidptosis-related genes (DRGs) were found to be associated with NP. The key genes were predominantly expressed in neurons and were lowly expressed in the NP group compared to SHAM. In addition, our macrophages used the APP (Amyloid precursor protein)-CD74 (MHC class II invariant chain) pathway to interact with neurons. These results suggest that NP is interconnected with the mechanistic processes of mitochondrial dysfunction and disulfidptosis, which may contribute to clinically targeted therapies.

Purpose: Ultrasound-guided modified thoracolumbar fascial plane block (MTLIP) has been reported effective for postoperative pain control following lumbar surgery. Although trauma of the Tianji robot-assisted lumbar internal fixation is reduced, the degree of pain cannot be ignored.MTLIP may improve operation efficiency and reduce puncture complications.This study aimed to explore whether MTLIP is not inferior to thoracolumbar fascial plane block (TLIP) in the treatment of lumbar internal fixation. Methods: This prospective double-blinded, non-inferiority randomized trial enrolled patients underwent Tianji robot-assisted lumbar internal fixation between April and August 2022 to either MTLIP or TLIP. The primary outcome was an effective dermatomal block area after 30 min. Secondary outcomes included the numeric rating scale (NRS) scores, nerve block operation time, puncture times, image clarity, patient satisfaction, intraoperative opioid consumption, complications/adverse reactions, and Oswestry Disability Index (ODI). Results: Sixty participants were randomized to MTLIP (n=30) and TLIP (n=30). The effective dermatomal block area 30 min after block was non-inferior in the MTLIP group (283.6 ± 62.6 cm²) compared with the TLIP group (261.4± 53.2 cm²) (P=0.145; estimated mean difference: − 22.17, 95% CI: − 52.19, 7.85; smaller than the non-inferiority margin of 39.5). Compared with TLIP, MTLIP showed shorter operation time, smaller puncture times, and better target definition and satisfaction scores (all P< 0.001). Sufentanil amount, remifentanil amount, PCIA sufentanil dosage, parecoxib amount, NRS scores (increased with time in the two groups but without inter-group differences), and complications were not significantly different between the two groups (all P> 0.05). Conclusion: This non-inferiority trial supports the hypothesis that MTLIP yields a non-inferior effective dermatomal block area compared with TLIP for Tianji robot-assisted lumbar internal fixation.

Purpose: Trauma, particularly extremity trauma, poses a considerable challenge in healthcare, especially among young adults. Given the severity of patient pain and the risks associated with excessive opioid use, managing acute pain in trauma centers is inherently complex. This study aims to investigate the application and benefits of ultrasound-guided nerve blocks for early pain management in patients with extremity trauma positioned supine. Methods: A comprehensive literature review was conducted to assess the effectiveness and advantages of ultrasound-guided peripheral nerve blocks in the acute pain management of extremity trauma patients in the supine position. Special emphasis was placed on evaluating the selection criteria, indications, contraindications, adverse reactions, and potential complications associated with these nerve block techniques. Results: Ultrasound-guided nerve blocks represent a safer and more precise option for managing pain in extremity trauma patients placed in the supine position. These techniques offer significant advantages in terms of reducing healthcare expenses, diminishing reliance on opioid medications, and mitigating opioid-related complications. Nonetheless, challenges may arise due to the necessity for patient cooperation during specific nerve block procedures. Conclusion: Ultrasound-guided nerve blocks present a promising avenue for early pain management in extremity trauma patients positioned supinely. Their implementation can lead to improved patient outcomes by alleviating pain severity, reducing opioid consumption, and cutting down healthcare costs. Further research and clinical integration of these techniques is imperative to enhance pain management protocols in trauma centers.

Background: To evaluate the effect of perioperative subanesthetic dose of esketamine on the postoperative recovery quality in patients undergoing laparoscopic gastrointestinal surgery. Methods: A total of 144 patients undergoing elective surgery for gastrointestinal tumors were selected and randomly assigned to either the esketamine group or the control group, with 72 patients in each group. Based on the standardized general anesthesia protocols, the esketamine group received an intravenous injection of esketamine at a dose of 0.2 mg/kg during the induction of anesthesia and an additional 0.2 mg/kg 30 minutes before the end of the surgery. Patient-controlled intravenous analgesia (PCIA) was administered for 48 hours, the esketamine group was treated with sufentanil (0.04 μg/kg/h) combined with esketamine (0.02 mg/kg/h) and sufentanil (0.04 μg/kg/h) was used as the control group. The scores of 40-items Quality of Recovery Scale (QoR-40) were recorded one day before surgery, one day after surgery, three days after surgery, and five days after surgery. Numerical Rating Scale (NRS) pain scores were recorded at postoperative intervals of 6 hours, 24 hours, 36 hours, and 48 hours. Levels of interleukin-6 (IL-6), tumor necrosis factor (TNF-α), and brain-derived neurotrophic factor (BDNF) in venous blood were analyzed prior to entering the operating room, upon arrival at the recovery room, and on the second postoperative day. Results: A total of 140 patients completed this study. Compared to the control group, the QoR-40 scores in the esketamine group were significantly higher at 1, 3, and 5 days post-surgery (Z = − 10.080, Z = − 8.178, Z = − 4.139, P < 0.05). In addition, the resting NRS scores were significantly lower at 6 hours, 24 hours, 36 hours, and 48 hours post-surgery in the esketamine group (Z=− 6.322, Z=− 5.736, Z=− 6.563, Z=− 5.920, P < 0.05). Conclusion: This study found that the perioperative use of subanesthetic esketamine improved early postoperative recovery quality and reduced postoperative pain levels in patients undergoing laparoscopic gastrointestinal surgery.
