Objective To explore the clinical application of the Shikani optical style(SOS)in guiding nasal tracheal intubation.Methods A retrospective analysis was made on clinical data of 60 patients who underwent selective operation under general anesthesia through nasal tracheal intubation from January 2017 to December 2022.According to the guidance methods of nasal tracheal intubation,the patients were divided into three groups with 20 cases in each group:video laryngoscope guided nasal tracheal intubation group(group V),fiberoptic bronchoscopy guided nasal tracheal intubation group(group F),and SOS guided nasal tracheal intubation group(group S).The grading of glottis exposure and epistaxis during tracheal intubation were recorded,as well as the success rate,completion time,and incidence of postoperative complications related to nasal tracheal intubation.Results The glottis exposure in the group F and group S were both grade Ⅰ.Among the group V,there were 7 cases of gradeⅠ,10 cases of gradeⅡ,and 3 cases of grade Ⅲ.The glottis exposure effect of patients in the group F and S was significantly better than that of the group V(Z =-4.274,P = 0.000;Z =-4.274,P = 0.000).There were 15 and 14 patients in the group F and the group S without epistaxis,and 5 and 6 patients with mild epistaxis,respectively.There were no patients with severe epistaxis in the group F and the group S.In the group V,there were 7 patients without epistaxis,10 patients with mild epistaxis,and 3 patients with severe epistaxis.The degree of epistaxis in the group F and the group S was significantly less than that in the group V(Z =-2.678,P =0.007;Z =-2.402,P =0.016).The median time for tracheal intubation in the group S was 37.5(34.3,41.5)s,significantly shorter than 45.0(39.8,72.5)s in the group V and 89.0(76.0,102.5)s in the group F(Z =15.703,P =0.013;Z =32.050,P =0.000),with the group V being significantly shorter than the group F(Z =-16.347,P =0.009).The nasal tracheal intubation failed in 2 cases in the group V,while was all successfully completed in the group F and the group S.The difference of success rate was not statistically significant among the three groups(P>0.05).There were no statistically significant differences in the rates of postoperative nasopharyngeal pain and nasal congestion among the three groups(P>0.05).Conclusion The method of SOS-guided nasal tracheal intubation can provide good glottis exposure and achieve a satisfactory success rate of tracheal intubation without increasing the risk of adverse reactions,which can be regarded as a safe and effective method of nasal tracheal intubation.

Objective To explore the safety and feasibility of single-segment paravertebral nerve block(PVNB)in elderly patients undergoing inguinal hernioplasty.Methods A retrospective analysis was made on clinical data of 58 elderly patients who underwent open tension-free inguinal hernioplasty from January 2016 to December 2022.According to the anesthesia method,they were divided into two groups with 29 cases in each:single-segment PVNB group(P group)and single subarachnoid block group(S group).Patients in the P group were given L1 single-segment PVNB guided by ultrasound combined with peripheral nerve stimulators or simple peripheral nerve stimulators by using 0.4%ropivacaine 20 ml.Patients in the S group underwent puncture in the interspinous space between L3/4 and received 0.5%bupivacaine 10 mg.The mean arterial pressure and heart rate before anesthesia(T0),at the time of skin incision(T1),at the time of hernia sac dissection(T2),and at the time of wound closure(T3)were recorded,and the block levels,anesthetic effect,remedial rate of fentanyl,local anesthetic toxicity,peripheral nerve injury,urinary retention,delirium,and nausea and vomiting of the patients were recorded.The patient's satisfaction with anesthesia was followed up.Results All the 58 patients underwent surgery smoothly.The difference in block levels was statistically significant between the two groups of patients(Z =-4.144,P =0.000),while the differences in the remedial rate of fentanyl,anesthesia effect,and anesthesia satisfaction were not statistically significant(χ2 =0.269,P =0.604;Z =-1.430,P =0.153;Z =-1.395,P =0.163).There were no statistically significant differences in mean arterial pressure and heart rate changes between the two groups at different time points(F =0.002,P = 0.960;F =0.260,P =0.612).The rate of urinary retention in the P group was significantly lower than that in the S group(0.0%vs.24.1%,Fisher's test,P =0.010).There were no statistically significant differences in rates of dilirium and nausea and vomitting(P>0.05).All the patients did not experience local anesthetic toxicity or peripheral nerve injury during the perioperative period.Conclusion Single-segment PVNB can provide comprehensive anesthesia and analgesia for elderly patients undergoing inguinal hernioplasty,helping to maintain the stability of intraoperative hemodynamics and reducing the risk of postoperative adverse reactions.

Objective To analyze the awareness of retinopathy of prematurity (ROP) among medical workers in Neonatal Intensive Care Unit (NICU) and obstetrical department, and parents of premature infants in Xiangyang area of Hubei Province. Methods This study used a questionnaire survey to select 115 parents of premature infants who underwent ROP screening from October 2020 to October 2022 and 85 neonatologists and obstetricians in NICU and obstetrics departments of Xiangyang Central Hospital in Hubei Province. The basic situation of premature infants was recorded, and the questionnaires were used to investigate the cognitive status of parents of premature infants, neonatologists, and obstetricians on ROP-related knowledge, and the results were recorded. Results A total of 115 valid questionnaires were collected from parents. Fifty-four parents (46.96%) had heard of ROP, and 61 parents (53.04%) had never heard of ROP. Among all parents who had heard of ROP, 10 parents (18.52%) learned through online queries or friends, 41 parents (75.93%) learned through NCIU doctors, and 1 guardian learned through NCIU nurses, 1 through obstetricians, and 1 through obstetric nurses. There were significant differences in the ways parents heard about ROP (χ²=122.709, P < 0.001). A total of 95 valid questionnaires were collected from medical staff, and only 7 medical staff could correctly write the ROP screening criteria, all of whom were NICU doctors. The NICU doctors had a higher rate of informing parents of premature infants about ROP than NICU nurses, obstetricians, and obstetric nurses (P < 0.05). Conclusion Parents of premature infants who undergo ROP screening in Xiangyang, Hubei Province have a serious lack of knowledge about ROP-related knowledge, and education level is an important factor influencing parents' understanding of ROP-related knowledge. Medical staff in relevant departments should also strengthen their learning of ROP-related knowledge. NICU doctors play the most important role in promoting ROP, and the publicity of ROP-related knowledge should be strengthened.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

The accreditation results of 38 tertiary general hospitals in Jiangsu province from 2018 to 2020 showed that there were weaknesses existing in the development of hospitals, including the radiosity and influence of tertiary hospitals, patient service mode, construction of medical technology capabilities and disciplines, medical quality and safety, nursing quality management and specialized nursing, and information construction. The author suggested that hospitals should return to functional positioning, improve the service quality, strengthen construction of hospital disciplines and technical projects, consolidate the foundation of quality and safety management, improve the level of information technology construction, for references for promoting the high-quality sustainable development of tertiary general hospitals.

Ultrasound-guided thoracic nerve block plays an important role in anesthesia and analgesia, but it is not easy to be mastered. This article discusses the application value of flipped classroom combined with 3D Body anatomy software for anesthesia specialty residents to learn ultrasound-guided thoracic paravertebral nerve block. This innovative education model includes three parts: before class, during class and after class. Before class, the teachers study the syllabus and make teaching micro-videos, and the cross-sectional anatomy added into the 3D Body anatomy software helps the residents understand. During class, teachers divide the residents into groups to report and exchange their learning experience, organize discussions, and finally give them comments. After class, the instructor will assign homework, assess the residents, and evaluate their satisfaction. This teaching model helps residents master the ultrasound-guided thoracic nerve block, and obtains satisfactory evaluation from the trainees, which is helpful for promotion.

To investigate the clinical features and influencing factors for new-onset atrial fibrillation (AF) early after coronary artery bypass grafting. Methods    The clinical data of 339 patients undergoing coronary artery bypass grafting in our hospital from January 2012 to January 2019 were retrospectively analyzed. There were 267 males and 72 females with an average age of 37-83 (58.03±8.90) years. The clinical features and influencing factors for new-onset AF after surgery were investigated. Results    There were 234 patients of off-pump coronary artery bypass grafting (OPCABG), with 36 (15.4%) new-onset AF patients after operation, among whom 16.1% were males and 12.5% were females. There were 105 patients of on-pump coronary artery bypass grafting (CABG), with 39 (37.1%) new-onset AF patients, among whom 40.7% were males and 25.0% were females. The incidence was higher after the CABG surgery than that after the OPCABG surgery (37.1% vs. 15.4%, P<0.05). There was no statistical difference in the incidence rate between males and females (P>0.05). The incidence of new-onset AF after surgery was higher in ≥60 years patients for both  operations (18.9% and 45.8%), which was significantly higher than that in <45 years patients (P<0.05). For both operations, the incidence of new-onset AF after surgery was high on the second day (24-48 h) after surgery, and most of the AF lasted for 1 day (P<0.05). The hypertension (OR=4.983, P=0.036), frequent premature atrial contraction or atrial tachycardia (OR=17.682, P=0.002), postoperative creatine kinase isoenzyme MB (CKMB) (OR=0.152, P=0.042), left anterior and posterior diameters (OR=17.614, P<0.001) and preoperative ejection fraction (OR=7.094, P=0.011) were influencing factors for new-onset AF after OPCABG. Diabetes (OR=11.631, P=0.020), other cardiac malformations (OR=29.023, P=0.002), frequent premature ventricular contraction or ventricular tachycardia (OR=0.047, P=0.001), and postoperative CKMB (OR=3.672, P=0.040) were influencing factors for new-onset AF after CABG. Conclusion    The incidence of new-onset AF after CABG is higher than that after OPCABG, and it increases with age increasing. There is no difference in the incidence between males and females. The influencing factors for the two operations are different.

Residency training is an indispensable part in the standardized training system of residents. The anesthesiology department of Peking University Third hospital launched the tutorial system in this residency training project as an initial exploration. Our study explored the concrete way of implementation of the tutorial system in the residency training program, including clarifying selection of the tutor, teachers' responsibilities, requirements for the residency, training contents and ways. Preliminary practice shows that tutorial system can enhance responsibilities of teachers, sense of belong of residents, and the quality of training.

Case-oriented Workshop training mode is a professional training method which has been highly praised by anesthesiologists in recent years. It is of great significance to stimulate the participation of anesthesiologists and strengthen the application of the extended focused assessment with sonography for trauma (EFAST) in perioperative anesthesia management. The training of EFAST is divided into two stages: the first stage is about the relevant knowledge of EFAST and watching standardized operations on site, and the second stage is for each trainee to practice the operations under the guidance of the teacher until they can complete them independently. The EFAST adopts Workshop training mode, and the trainees can complete the target area scanning in about 90 seconds on average. It can maximize the training effectiveness and comprehensively improve the trainees' mastery of knowledge and skills in an all-round way. It is a training mode worthy of promotion in anesthesiology department.

Objective:To analyze clinical outcomes of myocardial incision and tearing for the treatment of myocardial bridge.Methods:A retrospective cohort study was conduct to review the clinical date of 29 patients who underwent surgical myotomy from January 2014 to January 2018 in the Second Hospital of Lanzhou University. A total of 11 patients(incision group) were experienced traditional myotomy on myocardial bridge that the myocardium was longitudinally incised along the direction of the coronary artery, while 18 patients(tearing group) were treated by myocardial incision combined with tearing that longitudinally incised myocardium and deeply tissue tearing. The operation time of surgical myotomy, the amount of bleeding, the number of branches of vascular injury and the number of ventricular ruptures during operation were compared between the two groups. After followed up half a year to one year, the clinical symptoms of angina pectoris, myocardial ischemia by electrocardiogram suggested, and coronary stenosis by coronary CT suggested were collected.Results:The operation time of surgical myotomy, the amount of bleeding patients and the number of branches of vascular injury during operation in the incision group were higher than those in the tearing group( P<0.05). There was no significant difference for the number of ventricular ruptures during operation( P>0.05). After followed up half a year to one year, there was no significant difference in the clinical symptoms of angina pectoris, myocardial ischemia by electrocardiogram suggested, and coronary stenosis by coronary CT suggested( P>0.05). Conclusion:Myocardial incision combined with tearing is a surgical procedure with short operation time and low bleeding risk, which is more beneficial than the traditional longitudinally incised for the myocardial bridge.
