Risk prediction model for respiratory complications after lung resection: An observational multicentre study.

Background: Patients undergoing lung surgery are at risk of postoperative pulmonary complications (PPCs). Identifying those patients is important to optimise individual perioperative management. The Clinical Prediction Rule for Pulmonary Complications (CPRPCs) after thoracic surgery, developed by the Memorial Sloan-Kettering Cancer Center, might be an ideal predictor.

Ephedrine shows synergistic motor blockade when combined with bupivacaine or lidocaine for spinal anesthesia in a rat model.

Background: Ephedrine is a direct/indirect vasoactive drug. In addition, it also possesses intrinsic local anesthetic properties, mainly due to its sodium-channel blockage. We investigated whether ephedrine demonstrates a synergistic effect with bupivacaine and lidocaine when injected via a spinal catheter into the spinal space of rats.

Risks factors and regression model for risk calculation of anesthesiologic intervention in topical and intracameral cataract surgery.

Purpose: To determine risk factors for anesthesiologist intervention during routine cataract surgery performed with topical and intracameral anesthesia and establish a regression model to identify high-risk patients.

Setting: Department of Ophthalmology, Clínica Universidad de Navarra, Pamplona, Spain.

Design: Prospective case series.

External validation and comparison of three scores to predict renal replacement therapy after cardiac surgery: a multicenter cohort.

Purpose: Cardiac surgery-associated acute kidney injury requiring renal replacement therapy (RRT) is independently associated with mortality. Several risk scores have been developed to predict the need for RRT after cardiac surgery. We have compared and verified the external validity of the three main available scores for RRT prediction after cardiac surgery: the Thakar score, the Mehta tool, and the Simplified Renal Index.

Timing of renal replacement therapy after cardiac surgery: a retrospective multicenter Spanish cohort study.

Background: The optimal time to initiate renal replacement therapy (RRT) in cardiac surgery-associated acute kidney injury (CSA-AKI) is unknown. Evidence suggests that the early use of RRT in critically ill patients is associated with improved outcomes. We studied the effects of time to initiation of RRT on outcome in patients with CSA-AKI.

Cardiac-surgery associated acute kidney injury requiring renal replacement therapy. A Spanish retrospective case-cohort study.

Background: Acute kidney injury is among the most serious complications after cardiac surgery and is associated with an impaired outcome. Multiple factors may concur in the development of this disease. Moreover, severe renal failure requiring renal replacement therapy (RRT) presents a high mortality rate.

Impact of prealbumin levels on mortality in patients with acute kidney injury: an observational cohort study.

Objective: We evaluated the prognostic value of prealbumin (transthyretin) levels in patients with acute kidney injury (AKI).

Study Design: This was a longitudinal, single-center, observational cohort study.

Setting: The setting was a university-affiliated hospital.

Serum C-reactive protein on the prognosis of oncology patients with acute renal failure: an observational cohort study.

Background: We undertook this study to evaluate the significance of the C-reactive protein level (CRP) as a prognostic factor in oncology patients with acute renal failure (ARF) during nephrology consultation.

Methods: The study was comprised of a cohort of 375 consecutive oncology patients who had been admitted to a university-affiliated hospital between March 1998 and April 2006 and had been diagnosed with ARF. One hundred and fifty nine patients with ARF who matched at least one of the RIFLE criteria on increased serum creatinine were included for subsequent analysis.

Karnofsky performance score in acute renal failure as a predictor of short-term survival.

Background: Karnofsky Performance Scale Index (KPS) is a measure of functional status that allows patients to be classified according to their functional impairment. We aim to assess if the prior KPS may predict the risk of death among patients with acute renal failure (ARF).

Methods: A cohort of 668 consecutive patients who had been admitted in an university-affiliated hospital between June 2000 and June 2006, and had been diagnosed with ARF, were studied.

Prognosis and serum creatinine levels in acute renal failure at the time of nephrology consultation: an observational cohort study.

Background: The aim of this study is to evaluate the association between acute serum creatinine changes in acute renal failure (ARF), before specialized treatment begins, and in-hospital mortality, recovery of renal function, and overall mortality at 6 months, on an equal degree of ARF severity, using the RIFLE criteria, and comorbid illnesses.

Methods: Prospective cohort study of 1008 consecutive patients who had been diagnosed as having ARF, and had been admitted in an university-affiliated hospital over 10 years. Demographic, clinical information and outcomes were measured.
