ABSTRACT

OBJECTIVE@#To investigate serum thyroid stimulating hormone (TSH) level and its changes with age in apparently healthy Chinese elderly population and analyze the differences between TSH levels detected using Roche and Snibe electrochemiluminescence immunoassay analyzers.@*METHODS@#General clinical data and frozen fasting serum samples were collected from 5451 apparently healthy Chinese elderly individuals (> 60 years) from 10 centers in different geographic regions in China. Thyroid function indexes including TSH level were detected using Roche and Snibe electrochemiluminescence immunoassay analyzer, and the median (2.5% and 97.5% quantiles) TSH level was calculated. The variations of TSH level among the participants with geographic regions, gender, and age (with an interval of 5 years) were analyzed to determine the influence of these factors on TSH level.@*RESULTS@#The reference ranges of serum TSH level established using Roche and Snibe electrochemiluminescence immunoassay analyzers were 0.42-9.47 mU/L and 0.36-7.98 mU/L, respectively, showing significant differences between the two methods (P < 0.001). The TSH levels measured at two centers in Western China were significantly higher than those at the other centers (P < 0.05). In elderly male population, serum TSH level tended to increase with age, which was not observed in elderly female population. At the age of 60-75 years, women generally had higher serum TSH level than men, but this difference was not observed in the population beyond 75 years.@*CONCLUSION@#In elderly population, serum TSH level can vary with geographic region, gender, and age, but there was no need for establishing specific reference ranges for these factors. The differences between different detection methods should be evaluated when interpreting the detection results of TSH level.

ABSTRACT

OBJECTIVE To evaluate the rationality of epinephrine in the treatment of drug-induced anaphylactic shock, and to provide a reference for further standardizing the treatment measures of anaphylactic shock. METHODS According to the relevant data of the reports of severe adverse drug reaction (ADR) of drug-induced anaphylactic shock provided by Chongqing ADR Monitoring Center from 2015 to 2022, the selection of treatment drugs, and the application of epinephrine in anaphylactic shock were analyzed retrospectively; the clinical outcomes of anaphylactic shock with different epinephrine administration methods were investigated. RESULTS A total of 1 415 cases of severe ADR related to drug-induced anaphylactic shock were reported, with a male-to-female ratio of 1.04∶1; the drugs that caused allergic shock mainly included anti-infective drugs (47.92%), TCM injections (9.12%); the patients who suffered from drug-induced anaphylactic shock within 10 min after medication accounted for 43.96%; 97.24% of patients were cured or improved, and 2.76% of patients died or did not been improved. Among 1 415 patients, 63.39% of patients were treated with epinephrine, and the patients who preferred epinephrine treatment accounted for 53.14%; the intramuscular injection, subcutaneous injection, intravenous injection and intravenous drip accounted for 33.78%, 30.32%, 25.75% and 1.23%, respectively. The initial dose range of epinephrine was 0.01-10 mg, and the most frequent single dose was 1 mg (44.70%). Excessive single doses of intramuscular injection, subcutaneous injection and intravenous injection accounted for 51.03% (148 cases), 53.13% (136 cases) and 91.47% (193 cases) respectively, and the risk of overdose in intravenous injection was higher (P<0.05). The patients receiving initial treatment with epinephrine had a higher improvement rate/cure rate than those who did not use epinephrine (98.14% vs. 96.23%, P=0.029); the patients who preferred epinephrine had a higher improvement rate/cure rate than those who did not preferred epinephrine (98.14% vs. 95.17%, P=0.031); the improvement rate/cure rate of patients receiving intramuscular injection of epinephrine was higher than those without intramuscular injection (99.01% vs. 96.69%, P=0.038). CONCLUSIONS There are some unreasonable phenomena in the treatment of drug-induced anaphylactic shock, such as inappropriate selection of drugs, insufficient use of epinephrine, delay of administration, inappropriate route of administration and excessive single dose.

ABSTRACT

BACKGROUND@#Immune checkpoint inhibitors (ICIs) are increasingly used as first-line therapy for patients with advanced non-small cell lung cancer (NSCLC) harboring no actionable mutations; however, data on their efficacy among patients presenting with intracranial lesions are limited. This study aimed to explore the efficacy and safety of ICIs combined with chemotherapy in advanced NSCLC patients with measurable brain metastasis at initial diagnosis.@*METHODS@#Our study retrospectively analyzed clinical data of a total of 211 patients diagnosed with driver gene mutation-negative advanced NSCLC with measurable, asymptomatic brain metastasis at baseline from Hunan Cancer Hospital between January 1, 2019 and September 30, 2021. The patients were stratified into two groups according to the first-line treatment regimen received: ICI combined with chemotherapy ( n = 102) or chemotherapy ( n = 109). Systemic and intracranial objective response rates (ORRs) and progression-free survival (PFS) were analyzed. Adverse events were also compared between the groups.@*RESULTS@#Compared with the chemotherapy-based regimen, the ICI-containing regimen was associated with a significantly higher intracranial (44.1% [45/102] vs . 28.4% [31/109], χ2 = 5.620, P = 0.013) and systemic (49.0% [50/102] vs . 33.9% [37/109], χ2 = 4.942, P = 0.019) ORRs and longer intracranial (11.0 months vs . 7.0 months, P <0.001) and systemic (9.0 months vs . 5.0 months, P <0.001) PFS. Multivariable analysis consistently revealed an independent association between receiving ICI plus platinum-based chemotherapy as a first-line regimen and prolonged intracranial PFS (hazard ratio [HR] = 0.52, 95% confidence interval [CI]: 0.37-0.73, P <0.001) and systemic PFS (HR = 0.48, 95% CI: 0.35-0.66, P <0.001). No unexpected serious adverse effects were observed.@*CONCLUSION@#Our study provides real-world clinical evidence that ICI combined with chemotherapy is a promising first-line treatment option for driver gene mutation-negative advanced NSCLC patients who present with brain metastasis at initial diagnosis.@*CLINICAL TRIAL REGISTRATION@#https://www.clinicaltrials.gov/ , OMESIA, NCT05129202.

ABSTRACT

Objective To study the effects of three ferroptosis inducers Erastin (Era), sulfasalazine (SASP) and artesunate (Art) alone or combined with gemcitabine hydrochloride (hcGEM) on the proliferation inhibition of Human pancreatic cell line PANC -1. Methods The CCK-8 method was used to detect the inhibitory effects of different concentrations of Era, SASP and Art alone or combined with hcGEM on the proliferation of PANC-1, and the combination index (CI) was used to judge whether three ferroptosis inducers combined with hcGEM had synergistic inhibitory effect on PANC-1. Results The three ferroptosis inducers and hcGEM alone or in combination could significantly inhibit the activity of PANC-1. The inhibitory effects were enhanced with the concentration increasing. The CI values of hcGEM-Era 4∶1 or 1∶4 combination group and hcGEM-SASP 1∶400 combination group were less than 1.The CI values of hcGEM-Art 1∶4 or 1∶16 combination group were less than 1 only within a certain concentration range. Conclusion The inhibitory effects of the three ferroptosis inducers and hcGEM alone or in combination were dose-dependent. The combination of hcGEM and three ferroptosis inducers could synergistically inhibit the proliferation of PANC-1.

ABSTRACT

OBJECTIVES@#To study the association between early-life factors (including birth weight, method of birth, gestational age, and history of gestational metabolic disorders) and pubertal timing in girls.@*METHODS@#The stratified cluster sampling method was used to select the girls in grades 2-3 and 7-8 from three primary schools and three middle schools in Guangzhou, China from March to December, 2019, and breast development was examined for all girls. A questionnaire survey was performed to collect the information on early-life factors. The multivariate logistic regression model was used to evaluate the association of gestational metabolic disorders, birth weight, method of birth, and gestational age with pubertal timing in girls. The Bootstrap method was used to assess the mediation effect of body mass index (BMI) (Z score) between high birth weight (≥4 000 g) and pubertal timing.@*RESULTS@#A total of 1 665 girls were enrolled, among whom 280 (16.82%) were judged to have early pubertal timing. The multivariate logistic regression analysis showed that high birth weight was associated with the increased risk of early pubertal timing (OR=2.12, 95%CI: 1.19-3.66, P=0.008). Nevertheless, no significant association was observed between other early-life factors and pubertal timing (P>0.05). The OR for the mediation effect of BMI (Z score) between high birth weight and early pubertal timing was 1.25 (95%CI: 1.09-1.47), accounting for 29.33% of the total effect of high birth weight on early pubertal timing.@*CONCLUSIONS@#High birth weight is associated with the increased risk of early pubertal timing in girls, and overweight/obesity may play a partial mediating role in the association between high birth weight and early pubertal timing in girls.

ABSTRACT

Based on GC-MS and network pharmacology, the active constituents, potential targets, and mechanism of essential oil from Gleditsiae Fructus Abnormalis(EOGFA) against cerebral ischemia/reperfusion(I/R) injury were explored, and the effective constituents were verified by experiment. To be specific, GC-MS was used identify the constituents of the volatile oil. Secondly, the targets of the constituents and disease were predicted by network pharmacology, and the drug-constituent-target network was constructed, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the core targets. Molecular docking was performed to investigate the binding affinity between the active constituents and the targets. Finally, SD rats were used for experimental verification. The I/R injury model was established, and the neurological behavior score, infarct volume, and pathological morphology of brain tissue were measured in each group. The content of interleukin-1β(IL-1β), interleukin-6(IL-6), and tumor necrosis factor-alpha(TNF-α) was determined by enzyme-linked immunosorbent assay(ELISA), and the protein expression of vascular endothelial growth factor(VEGF) by Western blot. A total of 22 active constituents and 17 core targets were screened out. The core targets were involved in 56 GO terms and the major KEGG pathways of TNF signaling pathway, VEGF signaling pathway, and sphingolipid signaling pathway. Molecular docking showed that the active constituents had high affinity to the targets. The results of animal experiment suggested that EOGFA can alleviate the neurological impairment, decrease the cerebral infarct volume and the content of IL-1β, IL-6 and TNF-α, and down-regulate the expression of VEGF. The experiment verified the part results of network pharmacology. This study reflects the multi-component, multi-target, and multi-pathway characteristics of EOGFA. The mechanism of its active constituents is related to TNF and VEGF pathways, which provides a new direction for in-depth research on and secondary development of Gleditsiae Fructus Abnormalis.

ABSTRACT

The generation of a tau-V337M point mutation mouse model using gene editing technology can provide an animal model with fast disease progression and more severe symptoms, which facilitate the study of pathogenesis and treatment of Alzheimer's disease (AD). In this study, single guide RNAs (sgRNA) and single-stranded oligonucleotides (ssODN) were designed and synthesized in vitro. The mixture of sgRNA, Cas9 protein and ssODN was microinjected into the zygotes of C57BL/6J mice. After DNA cutting and recombination, the site homologous to human 337 valine (GTG) in exon 11 was mutated into methionine (ATG). In order to improve the efficiency of recombination, a Rad51 protein was added. The female mice mated with the nonvasectomy male mice were used as the surrogates. Subsequently, the 2-cell stage gene edited embryos were transferred into the unilateral oviduct, and the F0 tau-V337M mutation mice were obtained. Higher mutation efficiency could be obtained by adding Rad51 protein. The F0 tau-V337M point mutation mice can pass the mutation on to the F1 generation mice. In conclusion, this study successfully established the first tau-V337M mutation mouse by using Cas9, ssODN and Rad51. These results provide a new method for developing AD mice model which can be used in further research on the pathogenesis and treatment of AD.

ABSTRACT

OBJECTIVE@#To verify the safety of three dimensional printing percutaneous guide plate assisted percutaneous kyphoplasty(PKP) in the treatment of osteoporotic vertebral compression fractures(OVCFs).@*METHODS@#The clinical data of 60 patients with OVCFs treated by PKP from November 2020 to August 2021 were retrospectively analyzed. There were 24 males and 36 females, aged from 72 to 86 years old with an average of (76.5±7.9) years. Routine percutaneous kyphoplasty was performed in 30 cases (conventional group) and three dimensional printing percutaneous guide plate assisted PKP was performed in 30 cases (guide plate group). Intraoperative pedicle puncture time (puncture needle to posterior vertebral body edge) and number of fluoroscopy, total operation time, total number of fluoroscopy, amount of bone cement injection, and complication (spinal canal leakage of bone cement) were observed. The visual analogue scale (VAS) and the anterior edge compression rate of the injured vertebra were compared before operation and 3 days after operation between two groups.@*RESULTS@#All 60 patients were successfully operated without complication of spinal canal leakage of bone cement. In the guide plate group, the pedicle puncture time was(10.23±3.15) min and the number of fluoroscopy was(4.77±1.07) times, the total operation time was (33.83±4.21) min, the total number of fluoroscopy was(12.27±2.61) times;and in the conventional group, the pedicle puncture time was (22.83±3.09) min and the number of fluoroscopy was (10.93±1.62) times, the total operation time was(44.33±3.57) min, the total number of fluoroscopy was(19.20±2.67) times. There were statistically significant differences in the pedicle puncture time, intraoperative number of fluoroscopy, the total operation time, and the total number of fluoroscopy between the two groups(P<0.05). There was no significant difference in amount of bone cement injection between the two groups(P>0.05). There were no significant differences in VAS and the anterior edge compression rate of the injured vertebra at 3 days after operation between two groups(P>0.05).@*CONCLUSION@#Three dimensional printing percutaneous guide plate assisted percutaneous kyphoplasty is safe and reliable, which can reduce the number of fluoroscopy, shorten the operation time, and decrease the radiation exposure of patients and medical staff, and conforms to the concept of precise orthopaedic management.

ABSTRACT

Objective:To analyze the risk factors that affect the occurrence of hypothermia during laparoscopic colorectal cancer surgery, and establish a nomogram warning model, and verify the model.Methods:The clinical data of 275 patients undergoing laparoscopic colorectal cancer surgery in Hainan Branch of Chinese People′s Liberation Army General Hospital from January 2019 to December 2020 were retrospectively selected as the modeling group. The patients were divided into hypothermia group and normal group according to whether hypothermia occurred during the operation, and multivariate Logistic regression analysis was used to screen the risk factors that affect the occurrence of hypothermia during the operation. To use R software to establish a nomogram early warning model, and use Hosmer-Lemeshow (HL), calibration curve, area under the ROC curve and clinical decision curve (DCA) to evaluate the prediction effect of the model. In addition, 60 patients undergoing laparoscopic colorectal cancer surgery in the hospital from January to April 2021 were selected as the verification group for external verification of the model.Results:The incidence of intraoperative hypothermia in 275 patients undergoing laparoscopic colorectal cancer surgery was 42.91% (118/275). In this study, 4 risk factors including anesthesia time >150 min ( OR = 3.939, 95% CI 1.762-8.804), intraoperative blood loss ≥150 ml ( OR = 2.053, 95% CI 1.187-3.550), intraoperative fluid supplement ≥1 500 ml ( OR = 2.084, 95% CI 1.199-3.624), and total CO 2 dosage≥200 L ( OR = 2.707, 95% CI 1.571-4.663) were included to construct an intraoperative hypothermia warning model. Internal verification: the area under the ROC curve was 0.797 (95% CI 0.744-0.851), the HL goodness of fit test of the Logistic regression model with χ2 = 6.27, P = 0.617, the predicted occurrence risk value of the calibration curve was basically the same as the actual occurrence risk value. External validation: the area under the ROC curve of the external validation group of the prediction model was 0.745 (95% CI 0.662-0.628). The 95% CI area of the GiViTI calibration curve did not cross the 45°diagonal bisector ( P = 0.735), and when the DCA threshold range was 0.01-0.97, the nomogram model was reasonable to predict intraoperative hypothermia and the patient could get high net benefit. Conclusions:The nomogram warning model established based on the risk factors of hypothermia during laparoscopic colorectal cancer surgery has good discrimination, consistency and clinical practicability, and can provide a certain reference value for intraoperative medical staff to predict the occurrence of hypothermia.

ABSTRACT

Objective@#To determine the feasibility and safety of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) in hysterectomy and sentinel lymph node (SLN) mapping for endometrial cancer by comparing its SLN detection rate and perioperative outcomes with those of laparoscopic staging. @*Methods@#In this multicenter prospective cohort study, 68 patients with early endometrial cancer between 2020 and 2021 in 2 tertiary referral centers in China were grouped to vNOTES (n=33) or laparoscopy (n=35). All the patients underwent hysterectomy with SLN mapping. @*Results@#The total successful SLN detection was 97.0% in the vNOTES group and 91.4% in the laparoscopy group (p=0.32), whereas the bilateral success rates were 81.8% and 80.0%, respectively (p=0.84). There was no difference in SLN detection observed between the 2 groups regarding the side-specific mapping efficacy quotient (89.4% vs 85.7%; p=0.05). The number of harvested SLNs, the location of SLNs, operative time, estimated blood loss, intraoperative and postoperative complications and hospital cost in the 2 groups were similar (p>0.05), but there were differences in the 2 groups; the one was postoperative exhaust time that was 18 vs. 21 hours (p=0.01), the other was median postoperative hospital stay which was 4 vs. 5 days (p=0.05). @*Conclusion@#This study suggests that lymph node mapping can be completed through the vNOTES procedure. It can ensure effective surgical staging and show the advantages of a fast recovery and good cosmetic effect.

ABSTRACT

OBJECTIVES@#To investigate whether evidence-based standardized nutrition protocol can facilitate the establishment of full enteral nutrition and its effect on short-term clinical outcomes in very preterm/very low birth weight infants.@*METHODS@#A retrospective analysis was performed on the medical data of 312 preterm infants with a gestational age of ≤32 weeks or a birth weight of <1 500 g. The standardized nutrition protocol for preterm infants was implemented in May 2020; 160 infants who were treated from May 1, 2019 to April 30, 2020 were enrolled as the control group, and 152 infants who were treated from June 1, 2020 to May 31, 2021 were enrolled as the test group. The two groups were compared in terms of the time to full enteral feeding, the time to the start of enteral feeding, duration of parenteral nutrition, the time to recovery to birth weight, the duration of central venous catheterization, and the incidence rates of common complications in preterm infants.@*RESULTS@#Compared with the control group, the test group had significantly shorter time to full enteral feeding, time to the start of enteral feeding, duration of parenteral nutrition, and duration of central venous catheterization and a significantly lower incidence rate of catheter-related bloodstream infection (P<0.05). There were no significant differences between the two groups in the mortality rate and the incidence rate of common complications in preterm infants including grade II-III necrotizing enterocolitis (P>0.05).@*CONCLUSIONS@#Implementation of the standardized nutrition protocol can facilitate the establishment of full enteral feeding, shorten the duration of parenteral nutrition, and reduce catheter-related bloodstream infection in very preterm/very low birth weight infants, without increasing the risk of necrotizing enterocolitis.

ABSTRACT

Objective:To explore the prognostic factors of epithelial ovarian carcinoma (EOC), construct a nomogram model, and evaluate the prognosis of EOC patients.Methods:A retrospective analysis was performed on clinicopathological data of 208 cases of EOC patients who received initial treatment in the First Affiliated Hospital of Army Medical University from August 11, 2016 to July 11, 2018, including age, preoperative ascites, preoperative neoadjuvant chemotherapy, surgical method, pathological type, pathological differentiation degree, surgical pathology stage, preoperative and post-chemotherapy serum cancer antigen 125 (CA 125) level, human epididymal protein 4 (HE4) level, platelet count and platelet/lymphocyte number ratio (PLR). The univariate and multivariate Cox risk ratio models were used to analyze the related factors affecting progression free survival (PFS) in EOC patients, and the prediction nomogram of PFS in EOC patients was established to evaluate its efficacy in predicting PFS. Results:Univariate analysis showed that preoperative neoadjuvant chemotherapy, pathological type, pathological differentiation degree, surgical pathology stage, serum CA 125 and HE4 level before operation and after chemotherapy, platelet count and PLR before operation and after chemotherapy were significantly correlated with PFS in EOC patients (all P<0.05). Multivariate analysis showed that surgical pathology stage, preoperative PLR, serum CA 125 and HE4 level after chemotherapy were independent prognostic factors affecting PFS of EOC patients (all P<0.01). The index coefficient of the prediction model for the prognosis of EOC patients established by this method was 0.749 (95% CI: 0.699-0.798), which had good prediction ability, and could help clinicians to more accurately evaluate the prognosis of EOC patients. Conclusion:The nomogram model constructed based on surgical pathology stage, preoperative PLR, serum CA 125 and HE4 level after chemotherapy could effectively predict the PFS of EOC patients after initial treatment, could help clinicians to screen high-risk patients, provide individualized treatment, and improve the prognosis of EOC patients.

ABSTRACT

Objective:To summarize the suspected cases of pertussis, to explore the pathogen, and to analyze the clinical features of pertussis.Methods:A retrospective study was conducted to analyze the clinical data of suspected pertussis cases who visited the Department of Infectious Diseases in the Children′s Hospital Affiliated to Capital Institute of Pediatrics from June 2015 to May 2019.Results:(1) The PCR test for respiratory secretions of Bacillus pertussis was completed in 400 cases, with 198 cases positive (49.5%). (2) Among the 198 cases, 158 cases with pertussis were less than 1 year old (79.8%), 113 cases had a clear history of close contact with cough patients (57.1%), and 162 cases were not vaccinated or did not complete full diphtheria and tetanus toxoids and pertussis(DTP) vaccination (81.8%). The incidence of spasmodic cough was 73.7%(146/198 cases); the duration from onset to diagnosis was (17.2±12.3) d; the incidence of cyanosis after cough was 31.3%(62/198 cases), cough with vomiting 17.7% (35/198 cases), inspiratory croup 12.1%(24/198 cases); other concomitant symptoms included wheezing, runny nose, fever, diarrhea, etc.(3) All the patients were divided into the pertussis group (198 cases), other pathogen group (104 cases), and unknown pathogen group (98 cases). Comparison of the clinical symptoms of the three groups showed the highest incidence of cyanosis after cough in pertussis group ( χ2=15.334, P<0.001), and the highest incidence of wheezing, dyspnea, fever, pulmonary rales and stridor in other pathogen group ( χ2=79.208, 38.214, 16.709, 44.794, 42.480, all P<0.001). The percentages of white blood cells, lymphocytes and platelets in the pertussis group were higher than those in the other two groups ( F=15.812, 18.198, 10.819, all P<0.001). Conclusions:Suspected cases of pertussis are infected with various pathogens.Improving the pertussis nucleic acid detection and respiratory virus detection can help to make a clear diagnosis.Pertussis is more common in infants under 1 year of age and in those who have not completed vaccination.The most prominent clinical symptom is spasmodic cough, and the incidence of cyanosis after cough is higher than that of patients infected with other pathogens.

ABSTRACT

Objective:To summarize the clinical characteristics of neonates with Pierre-Robin sequence (PRS) who received mandibular distraction osteogenesis (MDO), in order to provide a basis for perioperative evaluation and management.Methods:Data of neonates diagnosed with PRS and receiving MDO in the Department of Neonatology, Guangzhou Women and Children′s Medical Center between December 2016 and December 2019 were collected for a retrospective study.According to the types of respiratory support needed before surgery, they can be categorized into 3 groups: the invasive ventilation group, the noninvasive ventilation group, the oxygen therapy/positioning therapy group.According to the usage of sedative and analgesic drugs after surgery, they were categorized into 2 groups: the sedative-analgesic group(Fentanyl Citrate and Midazolam) and the single sedative group(Midazolam alone).Results:A total of 31 children were admitted, 22 cases of whom received MDO at an age of (22.09±8.42) d, including 11 cases in the invasive ventilation group, 5 cases in the non-invasive ventilation group, and 6 cases in the therapy/positioning therapy group before surgery; there was statistical significance in severe respiratory distress (81.8% vs.60.0% vs.0) and feeding difficulties (100.0% vs.80.0% vs.50.0%) among the 3 groups (all P<0.05), while there was no difference in laryngomalacia rate(63.6% vs.20.0% vs.33.3%), non-gain in weight before surgery(81.8% vs.80.0% vs.66.7%), postoperative ventilation duration[(7.5±3.4) d vs.(7.2±5.3) d vs.(6.9±4.1) d]and hospital stay[(36.3±9.3) d vs.(34.1±0.3) d vs.(33.8±7.5) d] (all P>0.05). Among these 22 patients, there were 9 cases in the sedative-analgesic group, and 13 cases in the single sedative group.Compared with the single sedative group, cases in the sedative-analgesic group had significantly lower extubation rate (0 vs.15.4%) and shorter hospital stay[(32.3±5.2) d vs.(39.8±7.3) d], and the difference were statistically significant (all P<0.05). Besides, there were no differences in postoperative ventilation duration[(7.4 ± 3.9) d vs.(7.6 ± 4.2) d]between both groups ( P>0.05). The postoperative remission rate of airway obstruction was 100%. Conclusions:MDO in children in their neonatal period could achieve favorable efficacy.The duration of postoperative ventilator support and hospital stay in children with severe airway obstruction could not be prolonged compared with children with mild obstruction, and postoperative sedation and analgesic management can reduce the extubation rate.
