1 Influence of Body Size and Composition on Response to Hydromorphone in ED Patients With Acute Pain

Pain is the most common complaint for patients presenting to the emergency department (ED). Inadequate pain relief is also a common problem in ED. Patients' pain perceptions and responses to intravenous opioids vary widely and are influenced by multiple factors. The objective of the current study is to examine the association between total body weight, BMI (body mass index) and clinical response to a fixed dose of intravenous hydromorphone.

Conditions
  1. Pain
Interventions
  1. Drug: Hydromorphone

The mean and inter-quantile ranges of pain intensity reduction post-treatment were compared among patients by Kruskal-Wallis test.. Effects of Single-nucleotide Polymorphisms of Opioid Metabolism (UGT2B7, -G840A) on the Correlation Between TBW and Change in Pain Intensity. --- G840A ---

Clinical responses to hydromorphone could be affected by the single-nucleotide polymorphisms (SNPs) in gene involving opioid metabolism (UGT2B7, -G840A). --- G840A ---

Primary Outcomes

Description: Participants were asked to rate their pain levels from 0 (=no pain) to 10 (= worst pain). The change in pain intensity was determined by subtracting the intensity reported before treatment from the intensity reported 30 minutes after treatment. Pearson correlation was used to assess the correlation between change in pain intensity and total body weight (TBW). The reported value represents the correlation coefficient.

Secondary Outcomes

Description: Participants were asked to rate their pain levels from 0 (=no pain) to 10 (= worst pain).
