Abstract

Geriatric patients with femoral neck fracture (FNF) have unacceptably high rates of postoperative complications and mortality. The purpose of this study was to compare the effects of epidural anesthesia versus peripheral nerve block (PNB) on postoperative outcomes in elderly Chinese patients with FNF. This retrospective study explored mortality and postoperative complications in geriatric patients with FNF who underwent epidural anesthesia or PNB at the Chinese People's Liberation Army General Hospital from January 2008 to December 2012. The electronic database at the Chinese People's Liberation Army General Hospital includes discharge records for all patients treated in the hospital. Information on patient demographics, preoperative comorbidity, postoperative complications, type of anesthesia used, and in-hospital, 30-day, and 1-year mortality after surgery was obtained from this database. Two hundred and fifty-eight patients were identified for analysis. The mean patient age was 79.7 years, and 71.7% of the patients were women. In-hospital, 30-day, and 1-year postoperative mortality was 4.3%, 12.4%, and 22.9%, respectively, and no differences in mortality or cardiovascular complications were found between patients who received epidural anesthesia and those who received PNB. More patients with dementia or delirium were given PNB. No statistically significant differences were found between groups for other comorbidities or intraoperative parameters. The most common complications were acute cardiovascular events (23.6%), electrolyte disturbances (20.9%), and hypoxemia (18.2%). Patients who received PNB had more postoperative delirium (P=0.027). Postoperative acute respiratory events were more common (P=0.048) and postoperative stroke was less common (P=0.018) in the PNB group. There were fewer admissions to intensive care (P=0.024) in the epidural anesthesia group. Key factors with a negative influence on mortality were acute cardiovascular events, dementia, male sex, age, American Society of Anesthesiologists score, acute respiratory events, intensive care admission, and comorbidities. PNB was not associated with lower mortality or lower cardiovascular complication rates when compared with epidural anesthesia in elderly patients with FNF.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 August 2015.
All research outputs
#6,542,416
of 8,610,582 outputs
Outputs from Clinical Interventions in Aging
#823
of 1,026 outputs
Outputs of similar age
#159,199
of 230,593 outputs
Outputs of similar age from Clinical Interventions in Aging
#52
of 68 outputs
Altmetric has tracked 8,610,582 research outputs across all sources so far. This one is in the 13th percentile – i.e., 13% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,026 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.4. This one is in the 7th percentile – i.e., 7% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 230,593 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 68 others from the same source and published within six weeks on either side of this one. This one is in the 2nd percentile – i.e., 2% of its contemporaries scored the same or lower than it.
