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 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.

RÉSUMÉ
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.

OBJECTIVE: Patients with chronic neuropathic pain (CNP) have a higher incidence to develop depression. However, its pathogenesis has not yet been fully elucidated. Here we aimed to investigate the role of inflammatory cytokines in CNP-related anhedonia, which is a core symptom of depression, and to explore the effects of ketamine and parecoxib on pain and anhedonia. METHODS: A rat model of spared nerve injury (SNI) was constructed to mimic CNP. Hierarchical cluster analysis of sucrose preference test (SPT) was applied to classify the SNI rats into anhedonia susceptible and unsusceptible. Inflammatory cytokines in medial prefrontal cortex (mPFC) of brain, serum and L2–5 spinal cord were measured. Moreover, effects of ketamine or parecoxib on mechanical withdrawal test (MWT) and SPT in anhedonia susceptible rats were detected. RESULTS: Tumor necrosis factor (TNF)-α was increased in mPFC, serum and and spinal cord of anhedonia susceptible rats. Furthermore, anhedonia susceptible and unsusceptible rats both increased the interleukin (IL)-1β level in mPFC, serum and spinal cord. IL-6 was altered in serum and spinal cord, but not in mPFC. IL-10 was significantly altered in mPFC and serum, but not in spinal cord. Additionally, ketamine treatment significantly attenuated the decreased results of MWT and SPT in anhedonia susceptible rats, and that parecoxib significantly improved the MWT score, but failed to alter the result of SPT. CONCLUSION: These findings suggest that abnormalities in inflammatory cytokines confer susceptible to anhedonia in a rat model of SNI. Ketamine, a fast-acting antidepressant, has pharmacological benefits to alleviate pain and anhedonia symptoms.

Objective To evaluate the relationship between silent information regulator 1 ( SIRT1)-extracellular-regulated kinase1∕2 ( ERK1∕2) pathway and chikusetsu saponin IVa-induced reduc-tion of isoflurane-elicited neurotoxicity in fetal rats in an in vitro experiment. Methods The hippocampal neurons isolated from rats at 16-18 days of gestation were primarily cultured for 7 days and divided into 3 groups ( n = 6 each) using a random number table method: control group ( Con group) , isoflurane group (Iso group) and chikusetsu saponin IVa plus isoflurane group (ChIV+Iso group). Hippocampal neurons were cultured routinely for 6 h in Con group. Hippocampal neurons were exposed to 1. 8％ isoflurane for 6 h in an incubator in Iso group. Chikusetsu saponin IVa 25μg∕ml was added to the culture medium, and hipp-ocampal neurons were incubated for 6 h and then exposed to 1. 8％ isoflurane for 6 h in an incubator in ChIV+Iso group. The supernatant was collected for determination of the amount of lactic dehydrogenase ( LDH) released, neuronal viability ( by CCK-8) and expression of SIRT1, ERK1∕2 and phosphorylated ERK1∕2 ( p-ERK1∕2) ( by Western blot) . Results Compared with Con group, the neuronal viability was significantly decreased, the amount of LDH released was increased, and the expression of SIRT1 and p-ERK1∕2 was down-regulated in Iso group ( P<0. 05) . Compared with Iso group, the neuronal viability was significantly increased, the amount of LDH released was decreased, and the expression of SIRT1 and p-ERK1∕2 was up-regulated in ChIV+Iso group ( P<0. 05) . Conclusion The mechanism by which chikuset-su saponin IVa reduces isoflurane-elicited neurotoxicity is related to activating SIRT1-ERK1∕2 pathway in fe-tal rats in an in vitro experiment.

Objective To investigate the effect of ketamine on the mitochondrial function of rat neurons subjected to anoxia. Methods Primarily cultured rat hippocampal neurons were seeded in culture dishes (35 mm in diameter) at the density of 5×105-1×106 cells∕ml, and divided into 3 groups (n=11 each) using a random number table: control group, anoxia group and ketamine group. The neurons were exposed to 90% N2 plus 10% CO2 50 ml∕min for 5 min in anoxia group. In ketamine group, ketamine was added to the culture medium with the final concentration of 20 μmol∕L at 1 h before anoxia, and then the neurons were exposed to 90% N2 plus 10% CO2 50 ml∕min for 5 min. After the end of treatment in each group, the dead neurons were detected using trypan blue staining, the ATP content was determined by ATP bioluminescence assay, and mitochondrial membrane potential was measured by rhodamine 123 staining. Results Compared with control group, the mortality rate of hippocampal neurons was significantly in?creased, and the ATP content and mitochondrial membrane potential were significantly decreased in anoxia group and ketamine group ( P<0.05) . Compared with anoxia group, the mortality rate of hippocampal neu?rons was significantly decreased, and the ATP content and mitochondrial membrane potential were signifi?cantly increased in ketamine group (P<0.05). Conclusion The mechanism by which ketamine amelio?rates anoxia?induced damage to rat neurons is related to improved mitochondrial function.

Objective To compare the effects of a single injection of palonosetron and tropise-tron to prevent postoperative nausea and vomiting (PONV ) in gynecological surgeries. Methods Sixty patients undergoing elective major gynecological surgeries with general anesthesia (Apfel score ≥ 3 ) were included and randomized to group P (palonosetron ) and group T (tropisetron),30 patients in each group.All patients received general anesthesia with tracheal intuba-tion,and palonosetron 0.25 mg or tropisetron 5 mg were injected before anesthesia respectively in two groups.Intravenous hydromorphine was delivered for postoperative analgesia in all patients. PONV were evaluated and followed up for 72 hours.The degree of PONV was recorded and the com-plete response rate (CR)and complete control rate (CC)were calculated.Results The degree of PONV in 0-24 h and 24-48 h was milder in group P than in group T (P <0.05),while in 48-72 h the degree of PONV was similar between the two groups.In group P,5 patients had vomiting postopera-tively with the failure period of treatment of (1 9.6±9.4)h,and no patients needed rescue treatments. While in group T,1 9 patients suffered from vomiting with the failure period of treatment of (20.6± 4.5)h,and rescue treatments were delivered 3 times in total.The CR and CC of preventing PONV in 0-24 h,24-48 h and 0-72 h were significantly higher in group P than in group T (P <0.05).The CR and CC of the two groups were comparable in 48-72 h postoperatively.Conclusion A preoperative single dose of palonosetron 0.25 mg is better than tropisetron 5 mg in preventing PONV within 48hours after gynecological surgery.

Objective To evaluate Effects of general anesthesia combined with thoracic paraver-tebral block(TPVB)on postoperative recovery after thoracoscopic pulmonary lobectomy. Methods Eighty patients were randomized into the general anesthesia group( G group)and general anesthesia combined TPVB group(GT group). Under the guidance of ultrasound,patients in the GT group received 20ml of 0. 5% ropivacaine for TPVB,and sevoflurane and propofol for combined anesthesia. Patients in the G group received sevoflurane,propofol and remifentanil for combined anesthesia. Extubation time,postoperative vis-ual analogue scale(VAS),quality of recovery(QoR)score,and adverse reaction were all recorded. Results Patients in the GT group had less extubation time and earlier ambulation time compared to the G group. Postoperatively,at the 1st,24th and 48th hour,patients in the G group had significantly higher VAS values both at rest and on movement than GT group(P < 0. 05). The opioid consumptions in GT group were lower than the G group(P < 0. 05). The QoR values of GT group at 24th and 48th hour[(152 ± 21)min and (175 ± 17)min]were significantly higher than the G group[(134 ± 25)min and(162 ± 20)min]respec-tively. There were significant differences in hospitalization expenses,the hospitalization stay and the inci-dence of complications between the two groups. Conclusion The ultrasound-guided paravertebral block can improve the quality of recovery in patients undergoing thoracoscopic pulmonary lobectomy.
