Official title
Pilot Study: Relationship Between Anesthetic Regimen and Bone Cement Implantation Syndrome
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The annual incidence of geriatric hip fractures in the United States is 325,000 and is projected to rise given the aging population.1 The mainstay of treatment is cemented hip hemiarthroplasty. Bone cement implantation syndrome (BCIS) is a serious perioperative complication unique to cemented arthroplasty characterized by hypoxia, hypotension, cardiac arrhythmias, and in severe cases, cardiac arrest. BCIS is associated with significantly higher rates of unplanned intubation, vasopressor use, prolonged hospitalization, and 30-day mortality. Given the rising incidence of hip fractures, the identification of readily modifiable risk factors for BCIS such as anesthetic regimen is crucial to reduce morbidity and mortality. However, a prospective study comparing the rate of BCIS development between general and neuraxial anesthesia is currently lacking. Additionally, no studies have examined how the anesthetic regimen affects histamine and complement levels. Therefore, this pilot study aims to investigate the effect of anesthetic regimen on BCIS development as well as on histamine and complement levels in patients undergoing cemented hemiarthroplasty for hip fracture. The investigators hypothesize that neuraxial anesthesia will be associated with lower rates of BCIS as well as lower histamine and complement levels compared to general anesthesia. The primary objective of this pilot study is to compare the effect of general and neuraxial anesthesia on the incidence and severity of BCIS in patients undergoing cemented hemiarthroplasty for hip fracture. Secondary objectives include examining postoperative outcomes associated with BCIS, such as cardiac arrhythmias, unplanned intubation, hypoxia necessitating supplemental oxygen, altered mental status, and in-hospital mortality. Additional objectives include comparing histamine and complement levels between anesthetic regimens as well as between patients with and without BCIS
