Carina resection and reconstruction is required when a tracheal tumor invades the tracheal carina. It is a relatively complicated surgical procedure that requires complex reconstruction to maintain airway continuity. The technical difficulty lies in minimizing the influence of anesthetic endotracheal intubation and maintaining good ventilation function during surgery by establishing appropriate ventilation channels, which are contradictory in many cases. Therefore, in order to achieve the optimal surgical outcome, we performed intratracheal tumor resection and carina reconstruction with the help of extracorporeal membrane oxygenation.

Background: Hypoxaemia in post-surgical patients of esophageal cancer (EC) is common in thoracic departments. However, few studies have investigated the role of high-flow nasal cannula (HFNC) compared with conventional oxygen therapy (COT).Methods: A retrospective study was implemented to enroll hypoxemic patients after esophagectomy who were treated by HFNC or COT immediately after extubation between January 2019 and December 2019.We compared the effect of HFNC or COT in patients regarding the vital signs and arterial blood gases, the incidence of anastomotic leakage, postoperative pulmonary complications (PPCs), sore throat/nose, and reintubation, length of stay, and sputum production. We also 3D reconstructed the postoperative chest CT, and compared the amount of lung volume loss caused by PPCs (pneumothorax, atelectasis, pulmonary consolidation and pleural effusion) between the two groups.Results: Compared to patients in COT group, sore throat/nose in HFNC group was lower, the sputum production was higher, and the total hospital stay was shorter. Compared to COT, HFNC treatment decreased systolic blood pressure (SBP) at day 1, diastolic blood pressure (DBP) at day 1-4, and heart rate (HR) at day 2-4, increased arterial partial pressure of oxygen (PaO 2 ) at day 1-4, and arterial oxygen saturation (SaO 2 %) at day 1-2. In addition, the rate of PPCs and anastomotic leakage in HFNC group were lower than those in COT group. Compared to COT, HFNC treatment significantly decreased the amount of lung volume loss caused by PPCs.Conclusions: HFNC can improve the hypoxemia of patients after esophagectomy, increase the flow of sputum, reduce the incidence of PPC and anastomotic leakage.

Objective. Pregnancy loss has negative impacts on both the physical and the mental health of expectant mothers, which calls for an in-depth investigation. In this study, we examined the effects of case management on patients with pregnancy loss after in vitro fertilization and embryo transfer (IVF-ET). Methods. 100 participants that had suffered pregnancy loss after IVF-ET-assisted pregnancy from January 2019 to March 2020 were divided into routine care and case management groups, each with 50 cases. For the routine care group, a doctor led the diagnostic and treatment processes and a nurse assisted with the treatment. For the case management group, a nurse led the patient diagnostic and treatment processes and a doctor controlled the diagnosis and treatment plan formulation. Case management models were established according to the comprehensive peripregnancy loss care of patients with pregnancy loss after IVF-ET-assisted pregnancy. The participants’ outcomes (satisfaction, anxiety, and depression) were assessed at the time of pregnancy loss and 1 and 3 months after pregnancy loss during follow-up of the routine care and case management groups. Results. There was no statistical difference between the patients in the two groups with regard to their general information statistics ( P > 0.05 ) or their satisfaction, anxiety, and depression at the time of pregnancy loss ( P > 0.05 ). One month after pregnancy loss, there was no statistical difference in anxiety between the two groups ( P > 0.05 ), but satisfaction was greater and depression was significantly reduced in the case management group compared with the routine care group ( P < 0.05 ). Conclusion. Case management care can have a positive effect on improving the satisfaction, anxiety, and depression of patients that have had pregnancy loss after IVF-ET.

Background How to maximally improve the drainage of intracranial and upper body venous and to reduce neurological complications during thoracic tumor‐causedsuperior vena cava replacement are still clinical problems to be solved. Methods We have innovatively used the bilateral jugular vein‐left femoral vein ECMO shunting to perform mediastinal tumor resection and superior vena cava replacement in a 50‐year‐old woman. Results During the operation, this technique maintained the patient's hemodynamic stability, improved the cerebral oxygen saturation and reduced the cerebral ischemia, hypoxia as well as the neurological complications. Conclusion It is indicated for patients with superior vena cava replacement who are unable to perform venous bypass (such as innominate vein to right atrial bypass) or venous shunting (such as differential pressure drainage from internal jugular vein to femoral vein).
