Objective To explore the reliability and safety of continuous monitoring of vital signs in patients using wireless wearable monitoring devices after video-assisted thoracoscopic surgery (VATS) for lung cancer. Methods The patients undergoing VATS for lung cancer in West China Hospital, Sichuan University from May to August 2023 were prospectively enrolled. Both wireless wearable and traditional wired devices were used to monitor the vital signs of patients after surgery. Spearman correlation analysis, paired sample t test and ratio Bland-Altman method were used to test the correlation, difference and consistency of monitoring data measured by the two devices. The effective monitoring rate of the wireless wearable device within 12 hours was calculated to test the reliability of its continuous monitoring. Results A total of 20 patients were enrolled, including 15 females and 5 males with an average age of 46.20±11.52 years. Data collected by the two monitoring devices were significantly correlated (P<0.001). Respiratory rate and blood oxygen saturation data collected by the two devices showed no statistical difference (P>0.05), while heart rate measured by wireless wearable device was slightly lower (=−0.307±1.073, P<0.001), and the blood pressure (=1.259±5.354, P<0.001) and body temperature(=0.115±0.231, P<0.001) were slightly higher. The mean ratios of heart rate, respiratory rate, blood oxygen saturation, blood pressure and body temperature collected by the two devices were 0.996, 1.004, 1.000, 1.014, and 1.003, respectively. The 95% limits of agreement (LoA) and 95% confidence interval of 95%LoA of each indicator were within the clinically acceptable limit. The effective monitoring rate of each vital signs within 12 hours was above 98%. Conclusion The wireless wearable device has a high accuracy and reliability for continuous monitoring vital signs of patients after VATS for lung cancer, which provides a security guarantee for subsequent large-scale clinical application and further research.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Objective    To investigate the short-term quality of life in patients after single-direction video-assisted thoracic surgery (VATS) for lung cancer, and explore the related influencing factors. Methods    Patients who underwent single-direction VATS for lung cancer in the Department of Thoracic Surgery, West China Hospital, Sichuan University from July 2020 to August 2021 were continuously selected. The QLQ-C30 and QLQ-LC13 were used to evaluate the quality of life of the patients after the surgery, and the influencing factors were analyzed. Results    A total of 193 patients were collected. There were 73 males aged 59.44±11.40 years, and 120 females aged 53.73±11.15 years. The QLQ-C30 score of the patients after single-direction VATS for lung cancer was 69.09±20.21 points. Univariate analysis and Pearson correlation analysis showed that age, occupation, anesthesia time, postoperative complications, postoperative antibiotic use time, postoperative hospital stay, insomnia, economic stress, hemoptysis, chest pain, dysphagia, arm or shoulder pain were associated with the quality of life (P≤0.05). The results of multiple regression analysis showed that anesthesia time, economic pressure, insomnia and chest pain had a significant impact on the overall quality of life 30 days after the surgery (P≤0.05). Conclusion    The anesthesia time, economic pressure, insomnia and chest pain are independent influencing factors for the quality of life after the VATS lung cancer surgery.

AIM: To observe and compare the clinical efficacy and safety of remimazolam and propofol alone and in combination in endoscopic retrograde cholangiopancreatography (ERCP) anesthesia. METHODS: A total of 120 patients undergoing elective ERCP were divided into the propofol group (P group), the remimazolam group (R group), and the remimazolam combined with propofol group (RP group) according to a random number table, with 40 patients in each group, and the three groups completed anesthesia according to the designated drug regimen (propofol in group P; remimazolam in group R; and remimazolam combined with propofol in group RP). General information, operation time and awakening time of the patients in the three groups were compared, as well as oxygen saturation (SpO

The effect of general anesthetics (GA) on the developing brain has been a research hotspot in the last two decades. Numerous studies have shown that GA could damage the developing brain and cause long-term cognitive impairment in the preclinical setting, while it remains controversial in the clinical context regarding this topic. In light of the limitations of directly translating the preclinical findings into clinical context, drawbacks of retrospective studies, lack of standard behavioral and mental assessing tools in clinical studies, and other confounding factors, it is difficult to gain an agreement on the issue. To improve the repeatability and persuasion of data in the field of GA-induced developing brain, we tried to integrally analyze the current status and progress of the topic and make it as reference for the related studies in the future.

Thirty-six puerperas who underwent emergency cesarean section at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 24, 2020 to February 9, 2020, who all wore medical surgical masks, were retrospectively included in this study. Anesthesia management was performed under tertiary medical protection measures. A dedicated anesthesia equipment was separately sterilized. Narcotic drugs were used for one patient only, and disposable medical supplies were used for anesthetic supplies. Contact transmission should be avoided when a neonate required resuscitation, and early isolation and nucleic acid testing were provided for the neonates. The rate of suspected cases of novel coronavirus (2019-nCoV) was 11% , and the rate of clinically diagnosed cases was 17% before surgery. The rate of clinically diagnosed cases of 2019-nCoV was 22%, the rate of confirmed cases was 8%, and the total positive rate of diagnosis was 31% after surgery. The rate of neuraxial anesthesia was 86%, the rate of general anesthesia was 14%, the time of spinal puncture was (15±7) min, the time of tracheal intubation under general anesthesia was (2.1±1.3) min, the operation time was (95±36) min, and blood loss was (276±166) ml. The Apgar score of newborns was 8.8 ± 0.5. There was 1 neonate whose mother was diagnosed as having 2019 novel coronavirous disease after operation, an oropharyngeal swab specimen was obtained at 36 h of birth, and the swab was tested positive for 2019-nCoV by nucleic acid testing. As of February 10, 2020, an anesthesiologist involved in the operation was diagnosed to have infection by 2019-nCoV. In conclusion, diagnosis of 2019 novel coronavirous disease during pregnancy is more difficult, it is necessary to perform anesthesia management for cesarean section under tertiary medical protection. Although the difficulty in anesthesia operation is increased under tertiary medical protection, anesthesiologists can carry out standardized anesthesia management and guarantee the safety of maternal and infants and anesthesiologists themselves as long as they are rigorously trained and adhere to protective protocols.

During the epidemic of coronavirus disease 2019 (COVID-19), the infection of the elderly population will bring great challenges to clinical diagnosis and treatment, outcome and management.Combined with the characteristics of anesthesia and the pathophysiological characteristics of COVID-19 on lung function impairment in elderly patients, Chinese Society of Anesthesiology formulated the " Recommendations for anesthesia management and infection control in elderly patients with COVID-19″. This recommendation expounds preoperative visit and infection control, anesthesia management protocol, anesthesia monitoring, anesthesia induction/endotracheal intubation, anesthesia maintenance and infection control, intraoperative lung protection strategy, anti-stress and anti-inflammatory management, hemodynamic optimization, infection control during emergence from anesthesia, and postoperative analgesia in elderly patients with COVID-19, and provides the reference for the safe and effective implementation of anesthesia management in elderly patients during the prevention and control of COVID-19 epidemic.

Tooth enamel is prone to be attacked by injurious factors, leading to a de/remineralization imbalance. To repair demineralized enamel and prevent pulp inflammation caused by biofilm accumulation, measures are needed to promote remineralization and inhibit bacterial adhesion on the tooth surface. An innovative material, poly (aspartic acid)-polyethylene glycol (PASP-PEG), was designed and synthesized to construct a mineralizing and anti-adhesive surface that could be applied to repair demineralized enamel. A cytotoxicity assay revealed the low cytotoxicity of synthesized PASP-PEG. Adsorption results demonstrated that PASP-PEG possesses a high binding affinity to the hydroxyapatite (HA)/tooth surface. In vitro experiments and scanning electron microscopy (SEM) demonstrated a strong capacity of PASP-PEG to induce in situ remineralization and direct the oriented growth of apatite nanocrystals. Energy dispersive X-ray spectroscopy (EDS), X-ray diffraction analysis (XRD) and Vickers hardness tests demonstrated that minerals induced by PASP-PEG were consistent with healthy enamel in Ca/P ratio, crystal form and surface micro-hardness. Contact angle tests and bacterial adhesion experiments demonstrated that PASP-PEG yielded a strong anti-adhesive effect. In summary, PASP-PEG could achieve dual effects for enamel repair and anti-adhesion of bacteria, thereby widening its application in enamel repair.

Objective To investigate the influence of epidural analgesia on labor duration under the new partogram recommendations using quantile regression.Methods In this study,we recruited 300 nulliparous women at full term who were hospitalized in Department of Obstetrics and Gynecology,Tongji Medical College,Huazhong University of Science and Technology from May to September,2018.The participants who were willing to receive epidural analgesia during labor were assigned to the epidural group (n=150),and those who were not to the control group (n=150).Labor duration and delivery outcomes were analyzed by Student's t test,Mann-Whitney U test,Chi-square test and Fisher's exact test.Quantile regression models were also used to investigate the effect of epidural analgesia on labor duration.Results The median durations of first-and second-stage labor in the epidural group were 600(400-840) and 66(45-98) min,respectively,which were significantly longer than those of the control group [420(320-610) and 52(33-87) min] (Z=-4.273,P＜0.001;Z=-3.210,P=0.001).Quantile regression analysis showed that,for the first stage of labor,epidural analgesia was associated with labor prolongation,and had significant effects on all the percentiles (all P＜0.05).The regression coefficients increased (95.630-285.000) correspondingly as the percentiles of the labor duration (from 10th to 90th percentiles) increased.For the second stage of labor,epidural analgesia showed a significant impact on prolongation only between the 25th and 75th percentiles (coefficients:10.000～18.143;all P＜0.05).Although the epidural group had a significant higher episiotomy rate [46.8％(65/139) vs 33.3％(48/144),x2=5.318,P=0.021],more times of urine catheterization during labor [1(0-1) vs 0(0-1),Z=-0.974,P=0.001]and higher rate of oxytocin administration during labor [48.7％(73/150) vs 30.0％(45/150),x2=10.952,P=0.001],when compared with the control group,there was no significant difference in cesarean section rate,assisted vaginal delivery rate and neonatal outcomes between the two groups (all P＞0.05).Conclusions Epidural analgesia may associated with the prolongation of the first and second stage of labor,especially with the first stage of labor,but has no adverse effects on maternal and neonatal outcomes.
