Significance of oliguria in critically ill patients with chronic liver disease.

Unlabelled: Clinical guidelines recommend using Kidney Disease Improving Global Outcomes (KDIGO) criteria for the diagnosis and classification of acute kidney injury (AKI) in patients with chronic liver disease (CLD). Concerns have been raised about the use of urine output (UO) criteria in CLD. We examined the significance of oliguria meeting the urine output criteria for AKI (AKI-UO) and examined its association with clinical outcomes in CLD patients.

LMA supreme versus facemask ventilation performed by novices: a comparative study in morbidly obese patients showing difficult ventilation predictors.

Background: We designed a study to compare ventilation characteristics performed in morbidly obese patients by medical students via the facemask to that via the LMA Supreme.

Methods: This prospective, randomized, crossover study included 31 ASA I-III morbidly patients showing difficult mask ventilation predictors. After induction of anesthesia, ten medical students with no previous clinical experience in airway management, clinically educated to facemask ventilation maneuvers, and theoretically educated to laryngeal mask use were supervised by a senior anesthesiologist during performance of 60 s facemask and LMA Supreme ventilation in a randomly assigned order.

Evidence of pulmonary aspiration during difficult airway management of a morbidly obese patient with the LMA CTrach.

We describe a pulmonary aspiration that occurred during tracheal intubation with the LMA CTrach (SEBAC, Pantin, France) in a male morbidly obese patient (178 cm height, BMI=48 kg m(-2)) admitted for elective gastric banding. Our report suggests that manipulations of the CTrach such as Up-manoeuvre may lead to pulmonary aspiration in the case of regurgitated gastric content.

A comparison of two techniques for inserting the Airtraq laryngoscope in morbidly obese patients.

We postulated that video-controlled tracheal intubation with the Airtraq laryngoscope using the reverse manoeuvre instead of the standard technique of insertion could facilitate the airway management of morbidly obese patients. For the reverse manoeuvre the laryngoscope is inserted 180 degrees opposite to that recommended, and once in place rotated into the conventional pharyngeal position. Eighty (40 lean and 40 morbidly obese) ASA I-III adult patients were randomly allocated to four equal groups to compare the standard technique to the reverse manoeuvre for inserting the Airtraq laryngoscope.
