Tranexamic acid (TXA) is known to decrease the risk for postoperative blood transfusion in total hip arthroplasty (THA) patients. However, non-human studies have observed correlations between TXA exposure and increased pain as well as decreased periarticular cell viability and cell death. A new study explored how TXA affects early pain outcomes by comparing THAs that did and did not include TXA exposure.This comparison included a consecutive series of 213 THAs without TXA exposure and 169 THAs that included topical TXA, all performed by a single surgeon. All operations included the same perioperative medical and pain control protocols. Data collection included inpatient pain scores, time to first opioid, and opioid consumption in morphine milligram equivalents; the relationship between these data and TXA use and 10 additional covariates was examined.Mean 24-hour pain scores were higher in patients whose surgeries included topical TXA compared to patients who were not given topical TXA (P=0.006). The topical TXA patients also asked for opioids significantly sooner than non-TXA patients (mean 152 minutes vs. 246 minutes; P=0.033). For patients who did receive topical TXA, average morphine milligram equivalents consumed during the first 24 hours after post-anesthesia care unit was 56.07, compared to 31.26 among patients who did not receive topical TXA (P&lt;0.001).&ldquo;Topical TXA use was associated with greater early postoperative pain and opioid consumption in primary THA patients,&rdquo; the study authors concluded. &ldquo;Findings were supported by the magnitude of observed effects and the likelihood of clinical relevance. Replication and consideration of potential adverse consequences of TXA use in elective settings is encouraged.&rdquo;The findings appeared in <a href="https://www.arthroplastyjournal.org/article/S0883-5403(20)30106-6/fulltext?rss=yes">The Journal of Arthroplasty</a>.<h2>THA Pain: &lsquo;Worse Than Death?&rsquo;</h2>The present study observed significantly higher pain in THA patients who received topical TXA than those who did not. <a href="https://www.docwirenews.com/docwire-pick/rheumatology-picks/worse-than-death-hip-arthroplasty/">A previous study</a> found that about 20% of all patients waiting to undergo THA are in significant pain and describe it as &ldquo;worse than death (WTD).&rdquo;The study included 2,073&nbsp;<a href="https://www.docwirenews.com/abstracts/orthopedic-abstracts/rates-and-risk-factors-for-revision-hip-arthroscopy/">THAs</a>&nbsp;performed in 2,073 patients (mean age, 67.4 years; mean body mass index [BMI], 28.5 kg/m2; 60% were female). Researchers evaluated any association between a EuroQol five-dimension (EQ-5D) questionnaire score &lt; 0 and the following variables: age, body mass index (BMI), sex, deprivation quintile, comorbidities, and functional outcomes measured by the&nbsp;<a href="https://www.docwirenews.com/abstracts/orthopedic-abstracts/undersedation-during-total-hip-arthroplasty-reduction-results-in-worse-patient-outcomes/">Oxford Hip Score (OHS)</a>. One year postoperatively, 1,555 THAs underwent EQ-5D and OHS again.In total, 391&nbsp;<a href="https://www.docwirenews.com/abstracts/orthopedic-abstracts/outpatient-total-hip-arthroplasty-performed-at-an-ambulatory-surgery-center-versus-hospital-outpatient-setting-complications-revisions-and-readmissions/">THA</a>&nbsp;patients (19%) were WTD prior to surgery. Factors associated with WTD included preoperative OHS, deprivation, and chronic obstructive pulmonary disease, EQ-5D scores significantly improved one year after surgery; the WTD rate fell to 35 (2%). Preoperative WTD had significantly poorer one-year OHS and satisfaction rates compared to patients who were not WTD before surgery.
