Identifying intraoperative events in a simulated laparotomy video: a multinational study of inattentional blindness among anesthesiologists.

Purpose: Medical errors may be occasionally explained by inattentional blindness (IB), i.e., failing to notice an event/object that is in plain sight.

Preoperative variables associated with transfusion requirements in orthotopic liver transplantation.

Background: Patients with end-stage chronic liver disease (CLD) and submitted to orthotopic liver transplantation (OLT) usually require blood transfusion during the procedure or in the post-operative period due to hemorrhage. Risk factors for transfusion need are not fully known. This study aimed to identify the factors associated with blood components requirements.

Can joint analysis of postoperative MELD, base excess and blood lactate levels be used as an index of postoperative outcome for patients submitted to liver transplantation?

Purpose: The objective of the present study was to evaluate the postoperative levels of classical or pure MELD and changes in lactate or base excess (BE) levels as possible predictive factors of the type of outcome of patients submitted to orthotopic liver transplantation (OLT).

Methods: The study was conducted on 60 patients submitted to OLT at the University Hospital, Faculty of Medicine of Ribeirão Preto, USP, between October 2008 and March 2012. The 30 latest survivor (S) and non-survivor (NS) cases were selected.

Prospective analysis of 44 consecutive liver transplants performed at a university hospital.

Purpose: To analyze the intraoperative and immediate postoperative biochemical parameters of patients submitted to orthotopic liver transplantation.

Methods: Forty four consecutive orthotopic liver transplants performed from October 2009 to December 2010 were analyzed. The patients (38 male and eight female) were divided into two groups: group A, survivors, and group B, non-survivors.

Analysis of 83 consecutive liver transplants performed at a tertiary care reference hospital in the interior of the state of Sao Paulo.

Purpose: To analyze pre-, intra- and immediate postoperative parameters of patients submitted to liver transplantation.

Methods: Eighty-three consecutive orthotopic liver transplants performed from January 2009 to July 2011 were analyzed. The patients were divided into 2 groups: A, survivors (MELD between 9 and 60) and B, non-survivors (MELD between 14 and 40), with 30.
