Objective:To investigate the occurrence and managements of poor recovery after total endoscopic middle ear surgery. Methods:A total of 302 cases（315 ears） who underwent endoscopic middle ear surgery in our hospital from June 2020 to June 2021 were collected. Follow up by means of endoscopy, pure tone hearing threshold, tympanogram was conducted at 1 month, 3 months, 6 months and 1 year after surgery to analyze the incidence, possible causes, treatment strategies and effects of poor results tympanic membrane healing and hearing recovery. Results:Among 302 patients（315 ears） followed up, there were 28 cases with poor recovery. There were fourteen cases of poor eardrum healing, of which 10 cases achieved healing of eardrum after tympanic membrane patching in the outpatient department, with a success rate of about 71.4%. TM recurrence adhesion occurred in 4 cases after surgeries of cholesteatoma and adhesive otitis media. One case completely recovered after self eustachian tube insufflation, while 2 cases maintained the degree of eardrum subsidence, and one ineffective patient chose resurgical treatment, with an effective rate was 75.0%. Failure in hearing improvement occurred in 8 cases, all of which underwent second surgical exploration, and seven cases were improved after the second surgery, with an effective rate of 87.5%. Among the 8 patients with no improvement or aggravation of hearing loss after surgery, four cases had postoperative B-type or C-type of tympanogram, and the hearing could not improve after self eustachian tube insufflation for secondary surgical exploration. and the hearing improved after the secondary surgery. Incorrect orientation of ossicular prosthesis was accounted for another 2 cases, the hearing was improved after the ossicular orientation adjustment. One patient with lateral healing of TM and failed hearing recovery was corrected by a second operation. One case of tympanosclerosis underwent stapes release surgery, but hearing recovery still failed. One patient had recurrent postoperative cicatricial atresia of external auditory canal, and the patient was reluctant to undergo reoperation. Postoperative delayed facial paralysis occurred in 1 case, and the facial paralysis recovered recovered after conservative treatments. Conclusion:Eardrum patch and eustachian tube autoflation are simple and effective early outpatient treatment for patient with poor recovery. For those who failed with conservative treatments such as eardrum patch or eustachian tube and poor hearing recovery, the second surgical exploration is safe and effective. Regular follow up after endoscopic middle ear surgery is necessary for the managements of poor recovery.

Objective To explore the impact of"knowledge-attitude-practice"(KAP)training mode on head nur-ses' core competency in healthcare-associated infection(HAI)prevention and control in a tertiary first-class general hospital.Methods Head nurses of 113 departments in a tertiary first-class general hospital were taken as the re-search objects.Guided by problems and demands,HAI training was conducted using the KAP training mode.The training was divided into two stages:a stage with problems of infection control and investigation of knowledge de-mands,as well as a stage with KAP training mode implementation.It included theoretical lectures,visits and lear-ning,and supervision on rectification.Scores of theory,supervision,and core competency of head nurses before training,1 month and 6 months after training were compared by the analysis of variance.SPSS 26.0 statistical soft-ware was used for analysis.Results The top three infection control problems in this hospital were hand hygiene,prevention and control of infection with multidrug-resistant organisms,as well as HAI prevention and control in the wards.The top three training modules required urgently by the head nurses were occupational exposure and self-protection,principles of medical waste disposal,as well as prevention and control of HAI in the wards.Both scores of theory and supervision after training were higher than those before training,with statistically significant diffe-rences(both P＜0.01).The core competencies of the head nurses were at a high level.After implementing KAP training mode,the scores of dimensions in critical thought and research,clinical nursing,leadership,and profe-ssional development,as well as the overall score of core competencies were all higher than before training.Diffe-rences were all statistically significant(all P＜0.05).The overall scores of dimensions in legal and ethical practice,education and consultation,as well as interpersonal relationship were all higher than before training,but the diffe-rences were not statistically significant(all P＞0.05).Conclusion KAP training mode can significantly improve the scores of theory,supervision,and core competencies of head nurses,and can be further promoted and applied in head nurses' infection control training.

Objective To investigate the application of permissive hypercapnia in the thoraco-scopic surgery of neonates with congenital esophageal atresia.Methods Thirty newborns with con-genital esophageal atresia,seventeen males,thirteen females,aged 1-5 days,weighing 1.42-3.28 kg, ASA physical status Ⅱ or Ⅲ,undergoing the thoracoscopic surgery,were randomly divided into group P and group C,n =1 5 in each group.The newborns were intratracheally intubated and adopted intravenous anesthesia combining inhalational anesthesia.FiO 2 100%,fresh gas flow 2 L/min,then adjusted the respirator parameters according to the results of airway pressure and arterial blood gas a-nalysis.Group P maintained PaCO 2 ranging at 60-80 mm Hg,group C maintained PaCO 2 ranging at 35-45 mm Hg.Arterial blood gas analysis was conducted respectively before artificial pneumothorax (T0 ),1 5 min after foundation of artificial pneumothorax (T1 ),30 min after foundation of artificial pneumothorax (T2 ),60 min after foundation of artificial pneumothorax (T3 )and 1 5 min after artifi-cial pneumothorax (T4 ).Two hours after surgery,a chest X ray photograph was taken to observe pneumothorax.The time from the end of the surgery to the ventilator weaning was recorded. Results At T1-T3 ,the PET CO 2 [(73.93 ± 3.53 )mm Hg vs.(41.53 ± 1.59 )mm Hg,(73.46 ± 3.04)mm Hg vs.(41.30±1.29)mm Hg,(74.13±2.85)mm Hg vs.(41.67 ±1.35)mm Hg]in group P were greatly higher than those in group C (P <0.05);the arterial blood pH value of group P (7.25±0.02 vs.7.38 ± 0.03,7.24 ± 0.01 vs.7.37 ± 0.03,7.25 ± 0.01 vs.7.38 ± 0.02 )were greatly lower than those in group C (P <0.05);PaCO 2 [(74.80±2.45)mm Hg vs.(41.93±1.39) mm Hg,(75.33±2.1 9)mm Hg vs.(42.01±1.31)mm Hg,(75.20±2.08)mm Hg vs.(42.13± 1.1 9)mm Hg ] were greatly higher than those in group C (P < 0.05 ).The incidence of pneumothorax of group P was obviously lower than that of group C (6.7% vs.40.0%,P <0.05 ). There was no statistically significant difference of the time from the end of surgery to the ventilator weaning [(3.6±0.6)d vs.(3.5 ±0.6)d]between the two groups.Conclusion Permissive hyper-capnia significantly reduces the incidence of pneumothorax in the thoracoscopic surgery of neonates with congenital esophageal atresia.Permissive hypercapnia (PaCO 2 60-80 mm Hg)can be safely ap-plied to the thoracoscopic surgery of neonates with congenital esophageal atresia.

Objective To investigate the clinical efficacy ofHejie Fenxiao Decoction on damp-heat patients with acute kidney injury (AKI).Methods Totally 68 patients were divided into the control group and the treatment group according to the patients’ willings. Both groups were given treatment, such as elimination of the incentives and symptomatic treatment. Besides, patients of the treatment group acceptedHejie Fenxiao Decoction for 30 days. The changes of renal function indexes, such as serum creatinine (SCr), blood urine nitrogen (BUN), uric acid (UA), albumin (ALB) and integral of TCM syndrome, were observed, and recovery ratio and clinical endpoints were compared.Results SCr and eGFR of both group were improved on day 14 (P<0.05). After treatment, the renal function recovery ratio and renal replacement ratio in the two groups showed obvious differences (P<0.05);although survival rate of treatment group was higher than control group, it showed no statistical significance (P>0.05);clinical endpoints analysis of the two groups showed statistical significance (P<0.05). The difference of integrals of TCM syndrome between the two groups showed statistical significance (P<0.05) on day 14.ConclusionHejie Fenxiao Decoction combined with basic regular Western medicine can better improve the clinical symptom, recover the renal function, and decrease the rate of renal replacement and death of AKI damp-heat patients.
