We present a case in which we electively used venovenous extracorporeal membrane oxygenation (VV-ECMO) to facilitate safe resection of a nearly obstructing airway tumor near the carina in a 37-year-old male. The patient was brought to the operating room and underwent bifemoral cannulation for VV-ECMO under light sedation while maintaining spontaneous ventilation. After VV-ECMO was initiated, general anesthesia was induced, and the tumor was resected via rigid bronchoscopy. After resection, the patient was intubated, weaned from ECMO, decannulated, awoken, extubated, and taken to the postanesthesia care unit for recovery...

Between March, 2016 and January, 2017, 53 patients underwent robotic-assisted esophagectomy with triple incisions. All the patients were intubated with Double lumen endotracheal tub with one-lung ventilation and CO2 pneumoperitoneum, and CO2 pneumothorax was used in 7 cases. Most of the patients could tolerate OLV and CO2 pneumoperitoneum, and 4 patients with CO2 pneumothorax had hypoxemia and required double-lung ventilation or high frequency ventilation; 15 patients developed postoperative pulmonary complications and were transferred to ICU...

Tetanus, an almost forgotten but serious disease Tetanus is the systemic consequence of a local infection with Clostridium tetani, that produces toxin which spreads in the systemic circulation. In developed countries, it is extremely rare. Women born before 1950 are a group at risk due to lower prevalence of immunisation. This report describes a case of tetanus. The patient is a previously healthy 82-year-old woman. She presented to primary care with a complaint of stiffness in the neck and jaw. A physical exam and basic laboratory tests were normal apart from a slightly increased blood pressure...

INTRODUCTION: Size 9 and 8 airways for men and women, respectively, have been proposed as most appropriate based on endoscopy. However, a limitation of this guideline is that ventilation was not assessed. METHODS: In this retrospective review of prospectively collected data, 149 patients requiring tracheal intubation for general anesthesia were included. The adequacy for manual and pressure-controlled mechanical ventilation and views at the distal end of each airway was assessed using a fiber-optic bronchoscope with various airway sizes (7, 8, 9, 10, and 11)...

Medical hardware and software device interoperability standards are not uniform. The result of this lack of standardization is that information available on clinical devices may not be readily or freely available for import into other systems for research, decision support, or other purposes. We developed a novel system to import discrete data from an anesthesia machine ventilator by capturing images of the graphical display screen and using image processing to extract the data with off-the-shelf hardware and open-source software...

BACKGROUND: Previous research has suggested correlations between the end-tidal partial pressure of carbon dioxide (PETCO2) and the partial pressure of arterial carbon dioxide (PaCO2) in mechanically ventilated patients, but both the relationship between PETCO2 and PaCO2 and whether PETCO2 accurately reflects PaCO2 in neonates and infants are still controversial. This study evaluated remote sampling of PETCO2 via an epidural catheter within an endotracheal tube to determine the procedure's clinical safety and efficacy in the perioperative management of neonates...

BACKGROUND: During lobectomy in patients with lung cancer, the operated lung is often -collapsed and hypoperfused. Ischemia/reperfusion injury may then occur when the lung is -re-expanded. We hypothesized that remote ischemic preconditioning (RIPC) would decrease oxidative lung damage and improve gas exchange in the postoperative period. METHODS: We conducted a single-center, randomized, double-blind trial in patients with nonsmall cell lung cancer undergoing elective lung lobectomy...

Increasingly complex pediatric patients and improvements in technology warrant reevaluation of the risk associated with anesthesia for diagnostic imaging. Although magnetic resonance imaging is the imaging modality of choice for children given the potentially harmful effects of computerized tomography-associated ionizing radiation, we dare to suggest that certain patients would benefit from the liberalization of our current standard. Incorporating the use of newer computerized tomography technology may improve safety for those that are already at higher risk for adverse events...

INTRODUCTION: Anesthesia machines have evolved to deliver desired tidal volumes more accurately by measuring breathing circuit compliance during a preuse self-test and then incorporating the compliance value when calculating expired tidal volume. The initial compliance value is utilized in tidal volume calculation regardless of whether the actual compliance of the breathing circuit changes during a case, as happens when corrugated circuit tubing is manually expanded after the preuse self-test but before patient use...

Univent tube (UT) and EZ-blocker were used for one-lung ventilation (OLV). UT is a single lumen tube with a small separate lumen containing a bronchial blocker. EZ-blocker differs with its unique y-shaped double-cuffed distal end. We aimed to compare these two airway devices effects on airway pressures, oxygenation, ventilation and haemodynamics during OLV. Patients undergoing elective thoracotomy for the first time were included in this prospective randomized study. Patients were divided into two groups as UT and EZ...

Endotracheal tube displacement or dislocation is a severe complication that can occur in patients who require prone position ventilation. We hypothesized the prone position tube (PPT) would reduce the incidence of displacement of an endotracheal tube in an adult prone operation compared to a traditional tube (TT). A total of 80 adult patients undergoing neurosurgery or spine surgery were recruited. Sixty patients with prone position ventilation were randomly divided into the traditional routine endotracheal tube group (Group TT, n = 30) and the prone position ventilation endotracheal tube group (Group PPT, n = 30)...

BACKGROUND: Low tidal volume (VT) during anesthesia minimizes lung injury but may be associated to a decrease in functional lung volume impairing lung mechanics and efficiency. Lung recruitment (RM) can restore lung volume but this may critically depend on the post-RM selected PEEP. This study was a randomized, two parallel arm, open study whose primary outcome was to compare the effects on driving pressure of adding a RM to low-VT ventilation, with or without an individualized post-RM PEEP in patients without known previous lung disease during anesthesia...

INTRODUCTION: Donation after circulatory death (DCD) is an underused source of donor lungs. Normothermic cellular ex vivo lung perfusion (EVLP) is effective in preserving standard donor lungs but may also be useful in the preservation and assessment of DCD lungs. METHODS: Using a model of DCD and prolonged EVLP, the effects of donor warm ischemia and postmortem ventilation on graft recovery were evaluated. Adult male swine underwent general anesthesia and heparinization...

Many existing metrics, such as Injury Severity Score (ISS), cannot fully describe many trauma patients because of comorbidities. This study developed and evaluated the Need For Trauma Intervention (NFTI) metric as a novel indicator of major trauma. The NFTI metric was developed from an analysis of 2,396 trauma patients at a Level I trauma center. Six commonly recorded registry variables were found to be indicative of major trauma and comprised the NFTI criteria: receiving packed red blood cells within 4 hr; discharge from the emergency department (ED) to the operating room within 90 min; discharge from the ED to interventional radiology; discharge from the ED to the intensive care unit (ICU) with an ICU length of stay (LOS) of 3 or more days; mechanical ventilation outside of procedural anesthesia within 3 days; or death within 60 hr...
