Randomized Controlled TrialAssessment of Postoperative Analgesic Drug Efficacy: Method of Data Analysis Is Critical.
Pain intensity ratings and opioid consumption (OC) are ubiquitous indicators of pain in postoperative trials of the efficacy of interventional procedures. Unfortunately, consensus on the appropriate statistical handling of these outcomes has not been reached. The aim of this article was, therefore, to reexamine original data obtained from a postoperative analgesic drug trial, applying a collection of standard statistical methods in analgesic outcome assessments. Furthermore, a modified integrated assessment method of these outcomes was evaluated. ⋯ Our analyses demonstrate that the applied statistical method may alter the statistical significance and estimates of effect size of analgesic outcome variables in postoperative pain trials. Our findings underline the importance of defining valid statistical methods for future analgesic drug trials. We propose an integrated assessment of longitudinally measured pain intensity and opioid consumption (PIOC). The method combines two interdependent analgesic outcomes, lowers the risk of mass significance, and provides more accurate representation of the dynamic nature of postoperative pain and analgesic drug efficacy.

Randomized Controlled Trial Multicenter Study Comparative StudyDifferences in Blood Pressure in Infants After General Anesthesia Compared to Awake Regional Anesthesia (GAS Study-A Prospective Randomized Trial).
The General Anesthesia compared to Spinal anesthesia (GAS) study is a prospective randomized, controlled, multisite, trial designed to assess the influence of general anesthesia (GA) on neurodevelopment at 5 years of age. A secondary aim obtained from the blood pressure data of the GAS trial is to compare rates of intraoperative hypotension after anesthesia and to identify risk factors for intraoperative hypotension. ⋯ RA reduces the incidence of hypotension and the chance of intervention to treat it compared with sevoflurane anesthesia in young infants undergoing inguinal hernia repair.
