Application value of using a SaCo videolaryngeal mask airway combined with a bronchial blocker in patients undergoing minimally invasive thoracoscopic surgery.

Department of Anesthesiology, Xidian Group Hospital Xi'an 710077, Shaanxi, China.
Objective: To investigate the efficacy of the SaCo videolaryngeal mask airway (VLMA) in combination with a bronchial blocker in patients undergoing minimally invasive thoracoscopic surgery.
Methods: A retrospective analysis was conducted on the clinical data of 120 patients who underwent minimally invasive thoracoscopic surgery from January 2022 to December 2023. Patients were grouped based on their treatment methods: 68 patients who received the SaCo VLMA combined with a bronchial blocker intraoperatively were designated as the L group, while 52 patients who received a tracheal tube combined with a bronchial blocker intraoperatively were designated as the E group.

Article Synopsis
- The study explored the use of electrical impedance tomography (EIT) to evaluate the impact of thoracic epidural blockade (TEB) combined with general anesthesia on lung function during one-lung ventilation (OLV) in patients undergoing thoracic surgery.
- Thirty patients were randomly assigned to either a control group or a TEB group, where EIT measurements and blood gas analysis were performed to assess pulmonary perfusion distribution and ventilation-perfusion (V/Q) matching at different stages of the procedure.
- Results indicated that TEB significantly decreased mean arterial pressure and worsened arterial oxygen levels and shunt percentages during OLV, suggesting it adversely affected respiratory function in these patients.
Impact of intravenous infusion of lidocaine on intrapulmonary shunt and postoperative cognitive function in patients undergoing one-lung ventilation.

Department of Anesthesiology, Affiliated Hospital of Yangzhou University, China.
Background: Intravenous infusion of lidocaine as an anesthesia adjuvant can improve patient outcomes, but its impact on intrapulmonary shunt during one-lung ventilation (OLV) has not been clarified.
Objectives: To determine the effect of intravenous lidocaine infusion on intrapulmonary shunt during OLV and postoperative cognitive function in video-assisted thoracoscopic surgery (VATS).
Material And Methods: Sixty patients who underwent OLV for thoracic surgery were randomized to receive intravenous infusion of lidocaine (lidocaine group, n = 30) or normal saline (control group, n = 30) for anesthesia induction.

Background: Our aim was to evaluate the influence of staged goal directed therapy (GDT) on postoperative pulmonary complications (PPCs), intraoperative hemodynamics and oxygenation in patients undergoing Mckeown esophagectomy.
Methods: Patients were randomly divided into three groups, staged GDT group (group A, n = 56): stroke volume variation (SVV) was set at 8-10% during the one lung ventilation (OLV) stage and 8-12% during the two lung ventilation (TLV) stage, GDT group (group B, n = 56): received GDT with a target SVV of 8-12% During the entire surgical procedure, and control group (group C, n = 56): conventional fluid therapy was administered by mean arterial pressure (MAP), central venous pressure (CVP), and urine volume. The primary outcome was the incidence of postoperative pulmonary complications within Postoperative days (POD) 7.
Repercussions of SARS-CoV-2 infection on intrapulmonary shunt in patients undergoing one-lung ventilation.

Article Synopsis
- The study examines how previous SARS-CoV-2 infections impact intrapulmonary shunt during one-lung ventilation (OLV) in patients undergoing thoracoscopic partial pneumonectomy.
- It included 80 patients divided into four groups: those without SARS-CoV-2 infection and those infected at various intervals post-infection (5-8 weeks, 9-12 weeks, and 13-16 weeks).
- Results showed that patients in the infected groups experienced higher intrapulmonary shunt and lower oxygen levels compared to the non-infected group during different phases of ventilation, suggesting impaired pulmonary function related to the infection.
