Hyperchloremia after noncardiac surgery is independently associated with increased morbidity and mortality: a propensity-matched cohort study.

TLDR
A retrospective cohort trial demonstrates an association between hyperchloremia and poor postoperative outcome and additional studies are required to demonstrate a causal relationship between these variables.
Abstract
BACKGROUND:The use of normal saline is associated with hyperchloremic metabolic acidosis. In this study, we sought to determine the incidence of acute postoperative hyperchloremia (serum chloride >110 mEq/L) and whether this electrolyte disturbance is associated with an increase in length of hospita

Guidelines for perioperative care in elective colonic surgery: Enhanced recovery after surgery (ERAS®) society recommendations

TL;DR: Based on the evidence available for each item of the multimodal perioperative care pathway, the Enhanced Recovery After Surgery (ERAS) Society, International Association for Surgical Metabolism and Nutrition (IASMEN) and European Society for Clinical Nutrition and Metabolicism (ESPEN) present a comprehensive evidence-based consensus review of peri operative care for colonic surgery.

Intravenous Fluids and Acute Kidney Injury

TL;DR: In the setting of established acute kidney injury, fluid management can be challenging, and impaired capacity of urine output and urine concentration and dilution should be taken into consideration when designing fluid therapy.

Association of intraoperative hypotension with acute kidney injury after elective noncardiac surgery.

TL;DR: Postoperative AKI is associated with sustained intraoperative periods of MAP less than 55 and less than 60 mmHg, which provides an impetus for clinical trials to determine whether interventions that promptly treat IOH and are tailored to individual patient physiology could help reduce the risk of AKI.

Prediction of Creatinine Clearance from Serum Creatinine

Donald W. Cockcroft, +1 more
- 01 Jan 1976 - 
TL;DR: A formula has been developed to predict Creatinine clearance from serum creatinine (Scr) in adult males: Ccr = (140 – age) (wt kg)/72 × Scr (mg/100ml) (15% less i).

Coding algorithms for defining comorbidities in ICD-9-CM and ICD-10 administrative data.

TL;DR: A multistep process to develop ICD-10 coding algorithms to define Charlson and Elixhauser comorbidities in administrative data and assess the performance of the resulting algorithms found these newly developed algorithms produce similar estimates ofComorbidity prevalence in administrativeData, and may outperform existing I CD-9-CM coding algorithms.

An Introduction to Propensity Score Methods for Reducing the Effects of Confounding in Observational Studies

TL;DR: The propensity score is a balancing score: conditional on the propensity score, the distribution of observed baseline covariates will be similar between treated and untreated subjects, and different causal average treatment effects and their relationship with propensity score analyses are described.

The environment and disease: association or causation?

TL;DR: This paper contrasts Bradford Hill’s approach with a currently fashionable framework for reasoning about statistical associations – the Common Task Framework – and suggests why following Bradford Hill, 50+ years on, is still extraordinarily reasonable.

Rapid saline infusion produces hyperchloremic acidosis in patients undergoing gynecologic surgery

TL;DR: Infusion of 0.9% saline, but not lactated Ringer's solution, caused a metabolic acidosis with hyperchloremia and a concomitant decrease in the strong ion difference and the amount of weak plasma acid.
