Reliability and benefit of estimated continuous cardiac output measurement using shunt-side SpO monitor in hemodialysis.

Introduction: Estimated continuous cardiac output (esCCO) is a novel technology that enables non-invasive and continuous monitoring of cardiac output. We compared the concordance in accuracies among esCCO measurements in the shunt limb and non-shunt limb.

Methods: In this single-center prospective observational study, we include Japanese patients who underwent dialysis at our center between April 27, 2021, and February 28, 2023.

Divided method of intercostal nerve block reduces ropivacaine dose by half in thoracoscopic pulmonary resection while maintaining the postoperative pain score and 4-h mobilization: a retrospective study.

Purpose: This study investigated whether the divided method of multi-level intercostal nerve block (ML-ICB) could reduce the ropivacaine dose required during thoracoscopic pulmonary resection, while maintaining the resting postoperative pain scores.

Methods: This retrospective, single-cohort study enrolled 241 patients who underwent thoracoscopic pulmonary resection for malignant tumors between October 2020 and March 2022 at a cancer hospital in Japan. ML-ICB was performed by surgeons under direct vision.

Life-threatening massive bleeding in the pulmonary trunk adjacent to the right ventricular outflow tract during the resection of a large mediastinal germ cell tumor: proposed safety measures in the absence of cardiovascular surgeons: a case report.

This report presents an unusual case of life-threatening massive bleeding in the pulmonary trunk adjacent to the right ventricular outflow tract during resection of a large primary mediastinal nonseminomatous germ cell tumor (PMNSGCT) in the absence of cardiovascular surgeons. The patient was a 21-year-old male whose large mediastinal tumor was diagnosed as an extragonadal PMNSGCT, which was a mixture of a yolk sac tumor and an immature teratoma. Generally, chemotherapy causes extensive peripheral tumor necrosis of PMNSGCTs, thus enabling their complete resection.

Intraoperative Multimodal Approach for Pain After Thoracoscopic Pulmonary Resection.

Background: The optimal preemptive analgesia for thoracoscopic surgery remains unclear. We evaluated the utility of intraoperative intravenous analgesia on postoperative pain and the postoperative course in patients who underwent thoracoscopic lobectomy.

Methods: We retrospectively reviewed 228 consecutive patients who underwent single-lobe thoracoscopic lobectomy for malignant pulmonary tumors between October 2017 and December 2019.

Risk factors for postoperative nausea and vomiting after thoracoscopic pulmonary wedge resection: pitfalls of an increased fentanyl dose.

Background: Thoracoscopic pulmonary wedge resection (TPWR) is a surgical procedure that can maintain lung function and is less physically invasive to a patient. However, the risk factors for postoperative nausea and vomiting (PONV) following TPWR remain unknown. We aimed to evaluate multiple risk factors of PONV after TPWR and the impact of PONV on postoperative outcomes.
