BACKGROUND While many studies have been conducted on sugammadex sodium and neostigmine in patients undergoing general anesthesia, few have explored their effects in patients with interstitial lung diseases (ILDs). MATERIAL AND METHODS Sixty-three patients who underwent transbronchial cryobiopsy under general anesthesia were enrolled in a prospective randomized study. The patients were randomly divided into 2 groups: neostigmine combined with atropine group (group C, n=32) and sugammadex group (group S, n=31).

Non-intubated video-assisted thoracic surgery (NIVATS) can be safely performed in lung volume reduction surgery for patients with severe pulmonary dysfunction. However, there is still no cohort observation on the effects of NIVATS on patients with pulmonary dysfunction undergoing different types of thoracic procedures. This retrospective study aimed to observe the effects of NIVATS for this kind of patients.

Background: The risk factors for postoperative complications in non-intubated video-assisted thoracoscopic surgery (VATS) have not been observed before. Here to develop a simple risk score to predict the risk of postoperative complications for patients who scheduling non-intubated VATS, which is beneficial to guide the clinical interventions.

Methods: A total of 1,837 patients who underwent non-intubated VATS were included from January 2011 to December 2018.

BACKGROUND Nonintubated video-assisted thoracic surgery (NIVATS) has been demonstrated to be safe and effective in patients. However, the risk factors for intraoperative hypoxia are unclear. This retrospective study aimed to identify the risk factors for the development of intraoperative hypoxia in patients undergoing NIVATS.

Objective: Single-stage sequential bilateral video-assisted thoracoscopic surgery (VATS) is a controversial procedure. In the present study, we retrospectively compared the outcomes of single-stage and two-stage VATS.

Methods: This study involved patients who underwent single-stage sequential bilateral VATS (SS-VATS group) or two-stage VATS at a 3-month interval (TS-VATS group) for treatment of non-small cell lung cancer from 2010 to 2018.

BACKGROUND A secondary contralateral thoracic surgery is a challenging procedure and is rarely indicated. We retrospectively compared the perioperative values to find out whether video-assisted thoracoscopic surgery under spontaneous ventilation is feasible for this surgery. MATERIAL AND METHODS Patients were retrospectively collected from January 1, 2015 to December 30, 2018 who underwent secondary contralateral video-assisted thoracoscopic surgeries with mechanical ventilation (MV-VATS group) or spontaneous ventilation (SV-VATS group).

BACKGROUND One-lung ventilation under general anesthesia is necessary for most thoracic surgical procedures. However, adverse effects may derive from mechanical ventilation in emphysema patients. At present, lung volume reduction surgery under spontaneous ventilation may attenuate these adverse effects.

BACKGROUND Most observations of non-intubated anesthesia under spontaneous breathing are small-cohort, non-homogeneous surgery types and lack an intubation control. We therefore retrospectively compared the perioperative conditions and postoperative recovery of non-intubated video-assisted thoracoscopic surgery (NIVATS group) and intubated VATS (IVATS group) with a propensity score-matching analysis. MATERIAL AND METHODS We case-matched 119 patients in the NIVATS group with patients in the IVATS group by a propensity score-matched analysis.

Objective: The aim of this report is to describe a case with Aspergillus vertebral osteomyelitis complicating pulmonary granuloma in an immunocompetent adult.

Clinical Presentation And Intervention: A 53-year-old male patient was found to have lesions on lumbar vertebra 5 months after thoracoscopic resection of pulmonary granuloma that lacked a definite etiology. Three operations on the lumbar lesions were performed successively; however, an Aspergillus infection was not confirmed until hyphae were clearly detected at the last surgery.

Objective: To compare negative expiratory pressure (NEP) technique with conventional test in detecting expiratory flow limitation (EFL) in chronic obstructive pulmonary diseases (COPD) patients.

Methods: EFL was measured with NEP technique and conventional method respectively in 72 COPD patients;EFL was measured with NEP technique in 20 COPD patients who failed to perform conventional test.

Results: EFL was detected in 54 of the 72 COPD patients.

Objective: To explore feasible and reliable methods for estnbolishment and of acute lung injury model in animal models.

Methods: Twenty-four healthy adult mongrel dogs with oleic acid-induced acute lung injury were evaluated for early-stage physiological response to acute lung injury using a balloon catheter system for measuring esophageal and gastric pressure.

Results: In canine models of early-stage oleic acid-induced acute lung injury that sustained spontaneous breathing, in terms of respiratory mechanics, some parameters obviously increased including the respiratory rate (RR), minute ventilation (VE), peak inspiratory volume (Vinsp, peak), mean inspiratory volume (VT/Ti), inspiratory airway resistance (Raw, insp) (P<0.

Objective: To evaluate the effects of different interventional strategies, namely controlled high-concentration oxygen therapy, continuous positive airway pressure (CPAP) and bi-level positive airway pressure (BiPAP) ventilation, on respiratory response and work of breathing (WOB) in canine models of early-stage acute lung injury (ALI).

Methods: After successful duplication of ALI models with oleic acid (diagnostic criteria: Pa(O2)/Fi(O2) View Article and Find Full Text PDF
