Transcutaneous carbon dioxide measurements in anesthetized apneic patients with BMI > 35 kg/m.

Transcutaneous carbon dioxide measurement (TcCO) offers the ability to continuously and non-invasively monitor carbon dioxide (CO) tensions when end-tidal monitoring is not possible. The accuracy of TcCO has not been established in anesthetized apneic patients with obesity. In this secondary publication, we present a methods comparison analysis of TcCO with the gold standard arterial PCO, in adult patients with body mass index (BMI) > 35kg/m who were randomized to receive high flow or low flow nasal oxygenation during post-induction apnea.

The effect of transnasal humidified rapid-insufflation ventilator exchange (THRIVE) versus nasal prongs on safe apnoea time in paralysed obese patients: a randomised controlled trial.

Background: Evidence is lacking regarding the efficacy of Optiflow transnasal humidified rapid-insufflation ventilator exchange (THRIVE™) in obese patients. We compared the impact of this technique at 70 L min with 4 L min oxygen via nasal prongs on safe apnoea times of paralysed obese patients.

Methods: We randomised adults with a BMI >35 kg m undergoing elective bariatric surgery.

ClearSight™ finger cuff versus invasive arterial pressure measurement in patients with body mass index above 45 kg/m.

Background: Measuring blood pressure in patients with obesity is challenging. The ClearSight™ finger cuff (FC) uses the vascular unloading technique to provide continuous non-invasive blood pressure measurements. We aimed to test the agreement of the FC with invasive radial arterial monitoring (INV) in patients with obesity.

Perioperative Blood Pressure Monitoring in Patients With Obesity.

Blood pressure monitoring plays a key part in the preoperative, intraoperative, and postoperative care of all patients. In patients with obesity, hypertension indicates increased metabolic and surgical risk and may signal the presence of significant medical comorbidities, including obstructive sleep apnea. Avoidance of hypertension postoperatively is necessary to minimize bleeding risk after surgery.

Vascular response and mechanical integrity of the new biodegradable polymer coated sirolimus-eluting PROLIM stent implanted in porcine coronary arteries.

Background: Although durable polymer coated drug-eluting stents (DES) are standard care in percutaneous coronary interventions, new stent platforms employing biodegradable polymer based drug delivery are increasingly being used in clinical practice.

Aim: To evaluate the short- (28 days) and medium-term (90 days) vascular effects of the new biodegradable polymer coated sirolimus-eluting stent - the PROLIM stent.

Methods: The objectives of the study were evaluated using standard angiographic and histological methods.
