Right visual double lumen endotracheal tube versus common right double lumen endotracheal tube lung isolation technique: A randomized controlled study

ObjectiveTo compare the clinical efficacy between right visual double lumen tube (VDLT) intubation and right common double lumen tube (DLT) intubation in lung isolation technique. MethodsA total of 57 patients undergoing thoracoscopic surgery with right DLT lung isolation technique in the First People's Hospital of Chenzhou City and West China Hospital from June 2020 to June 2021 were randomly divided into two groups: a DLT group (n=29, 16 males and 13 females, with a mean age of 54.3±13.2 years) and a VDLT group (n=28, 18 males and 10 females, with a mean age of 55.1±13.7 years) at 1 : 1 with random number table generated by the computer. The clinical data of the two groups were compared. ResultsCompared with the DLT group, the catheter positioning time in the VDLT group was statistically shorter (74.9±47.5 s vs. 151.6±88.9 s, P<0.001), the right upper lung occlusion rate (21.4% vs. 51.7%) and the intraoperative re-adjustment catheterization rate (14.3% vs. 48.3%) were lower (P<0.05). The quality of lung collapses immediately after thoracotomy (67.9% vs. 24.1%) and 20 minutes after thoracotomy (100.0% vs. 75.9%) were improved (P<0.05). There was no significant difference in the rate of fiberoptic bronchoscope assistance for positioning, or the incidence of pharynx pain and hoarseness between the two groups (P>0.05). ConclusionCompared with common DLT, VDLT is more efficient, accurate and intuitive in the location of right bronchial intubation.

The Diagnosis and Surgical Treatment of Pulmonary Sequestration

Abstract: Objective To summarize the clinical experiences and surgical treatment of pulmonary sequestration (PS) in order to improve the diagnosis and treatment of PS. Methods Between August 1993 and February 2007, our department enrolled 21 PS patients, 8 male patients and 13 female patients, with the age ranging from 13 to 70 years old. The patients were examined by chest radiography, computerized tomography (CT), computerized tomography angiography (CTA), magnetic resonance imaging (MRI), position emission tomographyCT(PET-CT) before the surgery. Sequestrectomy was performed on patients with extralobar sequestration (ELS) and lobectomy was performed on patients with intralobar sequestration (ILS). There were 10 cases of left lower lobectomy, 3 cases of right lower lobectomy, 4 cases of left sequestrectomy, 3 cases of right sequestrectomy and 1 case of total pneumonectomy. Results Postoperative pathology confirmed all cases of PS, including 7 cases of ELS and 14 cases of ILS. Seven patients were diagnosed to have PS by preoperative diagnostic procedures. During the surgery, we found aberrant supporting arteries from the general circulation in 18 cases among which 11 were supported by the thoracic aorta, 6 by the abdominal aorta and 1 by both the thoracic and abdominal aorta. The diameter of the aberrant artery was between 0.2 cm and 1.1 cm (mean 0.7 cm). Double ligation and transfixion were performed during the operation. In addition, we found venous drainage through the inferior pulmonary vein in 3 patients and double ligation was performed. No perioperative death or complications occurred. Followup was done till January 2009 on all the patients but one with a followup rate of 95.2% (20/21). The followup time ranged from 12 to 67 months. All patients survived well except that 1 died from liver metastasis 2 years after the operation because of lung cancer. Conclusion PS is rare and its symptoms are nonspecific, which can cause misdiagnosis and missed diagnosis. The diagnosis of PS mainly depends on CT, CTA, MRI and selected arteriography. Once diagnosed, PS should be removed by surgery. During the surgery, aberrant vessels should be separated and treated with double ligation and transfixion. As for those big aberrant vessels, transfixion can be performed after vascular decompression.

摘要： 目的 评价升主动脉近端隔离装置（Heartstring和Enclose近端吻合装置）在非体外循环冠状动脉旁路移植术（OPCAB）中的应用效果。 方法 2006年1月至2008年2月收治了150例合并升主动脉近端钙化的冠心病患者，其中男102例，女48例；年龄55～78岁，平均年龄69岁。所有患者在冠状动脉旁路移植术中应用升主动脉近端隔离装置，大隐静脉与升主动脉近端共完成251个吻合口，升主动脉近端吻合口1～3个/例，大隐静脉桥血管完成后应用流量仪进行流量测定。术后观察神经系统并发症的发生情况。 结果 术后死于低心排血量综合征1例（067%）；二次开胸止血2例，其中1例为乳内动脉床渗血，1例为胸骨后出血；其余患者术后24 ｈ胸腔引流量为100～200 ml。所有患者均于术后24～48 ｈ内顺利拔除气管内插管；术后均未出现明确的昏迷、肢体偏瘫、语言障碍及运动不协调等神经系统并发症；大隐静脉桥血流量为28.5～70.1 L/min（53.7± 23.9 L/min）。术后随访145例，随访率97.32%，随访时间3个月～1年；4例失访。随访期间患者未发生迟发性脑出血或脑梗死等神经系统并发症。结论 在OPCAB术中应用Heartstring和Enclose升主动脉近端隔离装置，安全、有效，能有效地降低脑卒中的发生率。

The correlation between post-traumatic stress disorder and perceived stress in suspected COVID-19 patients quarantined in hospital

ObjectiveTo understand the relationship between post-traumatic stress disorder (PSTD) and perceived stress in suspected coronavirus disease 2019 (COVID-19) patients quarantined in hospital.MethodsA cross-sectional study of 93 suspected COVID-19 patients in one of grade-A tertiary hospital in Southwest China was carried out to evaluate the incidence of perceived stress and post-traumatic stress symptoms among these patients using the standardized Perceived Stress Scale-10 (PSS-10) and PTSD Checklist-5 (PCL-5), respectively. Pearson correlation was used to analyze the correlation between PCL-5 and PSS-10 scores.ResultsTotal PSS-10 and PCL-5 scores were 16.7±5.2 and 17.0±11.6 in 93 suspected COVID-19 patients, respectively. Positive correlations between PSS-10 and PCL-5 scores were detected (Pearson’s r=0.722, P=0.000).ConclusionsThe occurrence and development of PSTD of suspected COVID-19 patients have the relationship with the early perceived pressure. It suggests that medical staff should identify and intervene the perceived pressure level of patients who are under quarantine as suspected COVID-19 early and effectively, so as to reduce the occurrence of PTSD.

Giant extralobar pulmonary sequestration with severe pleural effusion in neonatal period: A case report

Giant extralobar pulmonary sequestration in newborns is still relatively rare in pulmonary diseases, and there are few relevant studies published. A neonate with the giant extralobar pulmonary sequestration accompanied by severe pleural effusion was reported here. After 12 days of birth, the diseased lung tissue was surgically extracted. The patient had an uneventful postoperative recovery and was discharged from the hospital. The case shows the advantage of early surgical treatment to extralobar pulmonary sequestration with severe pleural effusion in neonatal period.
