ObjectiveTo explore the risk factors for tracheal stenosis caused by tracheotomy or intubation.MethodsFrom July 2010 to July 2020, a total of 44 patients were suffered with tracheal stenosis caused by tracheotomy or intubation at the First Affiliated Hospital of Hunan Normal University as case group (n=44), and 34 patients were suffered tracheotomy or intubation without tracheal stenosis as control group (n=34). The clinical application of intratracheal tube cuff diameter was investigated by univariate comparison, ROC analysis and multivariate logistic regression analysis.ResultsUnivariate analysis showed intratracheal tube cuff diameter (C)/transverse diameter at the level of the clavicle >150%, intubation time>7d, tracheal intubations/tracheostomy ≥2, recurrent respiratory tract infections and replacement of tracheal tube≥ 2 were the influence factors of posttracheostomy tracheal stenosis (PTTS) and postintubation tracheal stenosis (PITS) (P<0.005). Multivariate Logistic regression analysis showed C/T>150% (OR=6.681, 95%CI: 1.164 - 38.363), intubation time>7d (OR=4.723, 95%CI: 1.413 - 15.779), tracheal intubations/tracheostomy ≥2 (OR=4.526, 95%CI: 1.133 - 18.083) and recurrent respiratory tract infections (OR=3.681, 95%CI: 1.177 - 11.513) were positively correlated with PTTS and PITS. The area under the ROC curve (AUC) of C/T>150% was 0.665 with the sensitivity of 0.364 and the specificity of 0.033 (95%CI: 0.555 - 0.775). AUC of intubation time>7 d was 0.717 with the sensitivity of 0.568 and the specificity of 0.133 (95%CI: 0.613 - 0.821). AUC of tracheal intubations/tracheostomy ≥2 was 0.683 with the sensitivity of 0.432 and the specificity of 0.067 (95%CI: 0.574 - 0.791). AUC of recurrent respiratory tract infections was 0.707 with the sensitivity of 0.614 and the specificity of 0.200 (95%CI: 0.603 - 0.811). However, there was no statistically significant difference C/T>150% and those clinical data in Z test (Z=0.839, P=0.402; Z=0.302, P=0.763; Z=0.751, P=0.453).ConclusionIntubation time>7 d, tracheal intubations/tracheostomy ≥2, recurrent respiratory tract infections, replacement of tracheal tube≥ 2 and C/T>150% are risk factors for PTTS and PITS.
Objective To find the most effective treatment for a patient with difficult selective biliary cannulation (DSBC) during endoscopic retrograde cholangiopancreatography (ERCP) by EBM practice. Methods Evidence was retrieved from The Cochrane Library (Issue 1, 2010), ACP online, NGC (1998 to June 2010), PubMed (1950 to June 2010), and CBM (1994 to June 2010). The collected evidence was then graded. Results After preliminary research, we identified 18 relevant articles. The evidence showed that pre-cutting technique could increase cannulation success rates in DSBC and was safe, effective, and time-saving for an experienced endoscopist. Pancreatic duct occupation was easier to perform than pre-cutting technique and could also increase selective cannulation success rates in DSBC. According to the evidence, together with endoscopist’s experience and the preference of the patient and his family, needle-knife precut papillotomy was performed. Successful selective biliary cannulation was accomplished after pre-cutting. Conclusion The current evidence suggests that pre-cutting technique and pancreatic duct occupation could increase selective cannulation success rates in DSBC. Patients’ condition and endoscopist’s experience should be considered properly before the operation.

Objective To summarize the blood supply to the sources and characteristics of advanced breast cancer，and explore the method，efficacy，and clinical applications of preoperative super-selective arterial catheterization chemoembolization under DSA for it. Methods Sixty patients with advanced breast cancer confirmed by the aspiration biopsy from February 2007 to October 2011 in this hospital were selected. Seldinger method was used，distributing of the tumor blood supply artery was identified and intubated the target artery by super-selective arterial catheterization via the femoral artery puncture under the DSA. Then，pirarubicin 60 mg plus paclitaxel 120 mg of two chemotherapy drugs was injected into slowly the target artery and the intervention infusion chemotherapy was performed，finally the tumor blood supply artery was embolizated by gelatin sponge particle. Results A total of 112 conclusive blood supply artery in 60 patients with DSA were found，including eight cases of single blood supply artery，52 cases of multiple blood supply arteries，mainly in the lateral thoracic artery and （or） internal thoracic artery-based. The complete remission rate was 25.0% （15/60），partial remission rate was 73.3% （44/60），stable disease rate was 1.7% （1/60），the total effective rate was 98.3% （59/60）. There was no progression disease. The median remission duration was 19 months，median survival time was 40 months. Conclusions The location of the original foci of breast cancer is closely related to blood supply arteries. The tumor in the lateral of the breast mainly dominates by the lateral thoracic artery blood supply. The tumor in the inner breast mainly dominates by the internal thoracic artery blood supply. The preoperative super-selective arterial catheterization chemoembolization under DSA can obviously improve the therapeutic effect，long-term survival，and the target of interventional chemoembolization.
ObjectiveTo investigate the application value of noninvasive ventilation (NIV) performed in patients with unplanned extubation (UE) in intensive care unit (ICU).MethodsThis was a retrospective analysis. The clinical data, application of NIV, reintubation rate and prognosis of UE patients in the ICU of this hospital from January 2014 to December 2018 were reviewed, and the patients were assigned to the control group or the NIV group according to the application of NIV after UE. The data between the two groups were compared and the application effects of NIV in UE patients were evaluated.ResultsA total of 66 UE patients were enrolled in this study, including 44 males and 22 females and with an average age of (64.2±16.1) years. Out of them, 41 patients (62.1%) used nasal catheter or mask for oxygenation as the control group, 25 patients (37.9%) used NIV as the NIV group. The Acute Physiology andChronic Health EvaluationⅡ score of the control group and the NIV group were (18.6±7.7) vs. (14.8±6.3), P=0.043. The causes of respiratory failure in the control group and the NIV group were as follows: pneumonia 16 patients (39.0%) vs. 7 patients (28.0%), postoperative respiratory failure 7 patients (17.1%) vs. 8 patients (32.0%), chronic obstructive pulmonary disease 8 patients (19.5%) vs. 6 patients (24.0%), others 5 patients (12.2%) vs. 4 patients (16.0%), heart failure 3 patients (7.3%) vs. 0 patients (0%), nervous system diseases 2 (4.9%) vs. 0 patients (0%), which showed no significant difference between the two groups. Mechanical ventilation time before UE were (12.5±19.8) vs (12.7±15.2) d (P=0.966), PaO2 of the control group and the NIV group before UE was (114.9±37.4) vs. (114.4±46.3)mm Hg (P=0.964), and oxygenation index was (267.1±82.0) vs. (257.4±80.0)mm Hg (P=0.614). Reintubation rate was 65.9% in the control group and 24.0% in the NIV group (P=0.001). The duration of mechanical ventilation was (23.9±26.0) vs. (21.8±26.0)d (P=0.754), the length of stay in ICU was (34.4±36.6) vs. (28.5±25.8)d (P=0.48). The total mortality rate in this study was 19.7%. The mortality rate in the control group and NIV group were 22.0% and 16.0% (P=0.555).ConclusionPatients with UE in ICU may consider using NIV to avoid reintubation.
ObjectiveTo investigate the feasibility and safety of non-intubation anesthesia in thoracic surgery.MethodsFrom September 2017 to December 2019, 296 patients were operated at department of thoracic surgery in our hospital. There were 167 males and 129 females with an average age of 50.69±12.95 years, ranging from 16 to 76 years. The patients were divided into two groups according to whether they were intubated: 150 patients were in a non-intubation group, including 83 males and 67 females with an average age of 49.91±13.59 years, ranging from 16 to 76 years, and 146 patients were in an intubation group including 84 males and 62 females with an average age of 51.49±12.26 years, ranging from 16 to 74 years. Intraoperative data, postoperative recovery, inflammatory response of the two groups were compared.ResultsThere was no statistical difference between the two groups in operation time, blood loss, the lowest oxygen saturation or other indicators (P>0.05). But the highest partial pressure of carbon dioxide of the non-intubation group was higher than that of the intubation group (P=0.012). The non-intubation group was superior to the intubation group in postoperative recovery and inflammatory response (P<0.05).ConclusionThe non-intubation anesthesia is safe and maneuverable in thoracic surgery, and it has some advantages in accelerating postoperative rehabilitation.
