We evaluated the results of hemodialysis performed with 106 double lumen catheters in 87 patients (mean age 52, range 10-82). 46 patients had chronic and 38 acute renal failure; 2 had respiratory distress syndrome and one refractory heart failure. Catheter flow ranged from 100 to 250 ml/min (mean 207) and effective clearance from 64 to 171 ml/min (mean 125). Only one catheter was used in 75 patients (86%), 2 in 7 and more than 2 in 5. Causes of failure included inadequate flow (9), coagulation (6) and displacement (4). In nine instances, severe complications developed: sepsis (3), local infection (4), hematoma (1) and vagal reaction (1). Three patient with catheters located in the subclavian vein developed vein stenosis, requiring angioplasty in 2 and graft in 1. Thus, double lumen catheter is easy to place and helps preserve future vascular sites in chronic hemodialysis.

One-lung ventilation is commonly used in lateral open chest surgery; however, it can increase pulmonary vascular resistance, which negatively affects Fontan circulation. Nevertheless, one-lung ventilation has a positive indication in post-Fontan patients. It allows surgery with lateral minimally invasive thoracotomy, which does not require a median sternotomy.

Background: Nonocclusive mesenteric ischemia (NOMI), a subtype of acute mesenteric ischemia, is primarily caused by mesenteric arterial vasoconstriction and decreased vascular resistance, leading to impaired intestinal perfusion.Commonly observed after cardiac surgery, NOMI affects older patients with cardiovascular or systemic diseases, accounting for 20-30% of acute mesenteric ischemia cases with a mortality rate of ∼50%. This review explores NOMI's pathophysiology, clinical implications in aortic dissection, and the unmet needs in diagnosis and management, emphasizing its prognostic significance.

: The development of microsurgical techniques has enabled reconstructive versatility in various clinical scenarios. Supermicrosurgery is an advanced microsurgical technique ensuring precise reconstructions by operating on small-caliber vessels and nerves, with applications in reconstructive surgeries. : This study aims to compare the effectiveness of four low-cost training models, thereby improving surgical precision and reducing the learning curve for novice surgeons.

We report a case of a 74-year-old female with a retrosternal goiter undergoing video-assisted thoracic surgery (VATS) for a left lung lower lobectomy, necessitating one-lung ventilation (OLV). We encountered a highly unusual complication: contralateral tension pneumothorax. Forty-five minutes into the surgical procedure, a sudden cardiovascular collapse occurred.

Department of Anesthesiology, The Second Hospital, Cheeloo College of Medicine, Shandong University, Jinan, 250033, People's Republic of China.
Background: Postoperative sore throat (POST) is a significant adverse effect after endotracheal intubation, especially with double-lumen endotracheal tubes (DLTs). Ultrasound-guided internal branch of the superior laryngeal nerve block (US-guided iSLNB) presents a potential intervention for POST. In this first randomized controlled trial to date, we aimed to investigate the effects of US-guided iSLNB, with or without perineural dexmedetomidine, on the incidence and severity of POST following DLTs.
