Postoperative prophylactic antibiotics in total joint arthroplasty.

ABSTRACT: The Center for Disease Control and Prevention recently released their 2017 Guideline for the Prevention of Surgical Site Infection. One of their recommendations is the ordering of a single dose of preoperative prophylactic antibiotics with no subsequent postoperative dosing; this recommendation includes perioperative antibiotics for patients undergoing total joint arthroplasty. At this time, the American Association of Hip and Knee Surgeons (AAHKS) does not agree with this recommendation vis-a-vis total joint arthroplasty because it contradicts current international standards of care with limited evidence and study. AAHKS still recommends postoperative antibiotics and recommends further research. Both the Board of Counselors and Board of Specialty Societies of the American Academy of Orthopaedic Surgeons have endorsed this AAHKS recommendation through an advisory opinion; the American Academy of Orthopaedic Surgeons Board of Directors adopted that advisory opinion in June 2017. A 2017 Foundation for Arthroplasty Research and Education prospective, randomized study is being undertaken to provide level I evidence for or against single-dose vs 24-hour antibiotic prophylaxis in primary total knee arthroplasty.

Project description:BackgroundPostoperative nausea and vomiting (PONV) after total joint arthroplasty is common and associated with delayed recovery. This study was performed to evaluate the efficacy of three different prophylactic regimens for PONV after total joint arthroplasty under general anesthesia.MethodsPatients undergoing primary total hip or knee arthroplasty were randomized to Group A (ondansetron), Group B (10 mg dexamethasone plus ondansetron and mosapride), or Group C (three doses of 10 mg dexamethasone plus ondansetron and mosapride). The primary outcome was the total incidence of PONV during postoperative 48 h. The secondary outcomes were complete response, rescue antiemetic treatment, opioid consumption, time until first defecation, postoperative appetite score, satisfaction score, length of hospital stay, blood glucose level, and complications.ResultsPatients in Group C experienced a lower incidence of total PONV (29.3%, p = 0.001) and a higher incidence of complete response (70.7%, p = 0.001) than did patients in Group A (51.9%, 48.2%, respectively). Patients in Group C also experienced a lower incidence of severe PONV (4.3%) than patients in Group A (25.9%, p<0.001) and B (20.4%, p<0.001). Moreover, less rescue antiemetic treatment (1.4 ± 0.5 mg Metoclopramide) and postoperative opioid consumption (1.8 ± 0.3 mg Oxycodone, 6.0 ± 1.0 mg Pethidine) was needed in Group C. Additionally, a shorter time until first defecation, shorter length of stay, and better postoperative appetite scores and satisfaction scores were detected in patients in Group C. A slight increase in the fasting blood glucose level was observed in Group C, and the complications were comparable among the groups.ConclusionCombined use of ondansetron, mosapride and three doses of dexamethasone can provide better antiemetic effectiveness, postoperative appetite, bowel function recovery, and pain relief than a single dose or ondansetron only.Trial registration informationThe protocol was registered at the Chinese Clinical Trial Registry (ChiCTR1800015896, April 27, 2018).

Project description:Duplex ultrasound is routinely used to evaluate suspected deep venous thrombosis after total joint arthroplasty. When there is a clinical suspicion for a pulmonary embolism, a chest angiogram (chest CTA) is concomitantly obtained.Two questions were addressed: First, for the population of patients who receive duplex ultrasound after total joint arthroplasty, what is the rate of positive results? Second, for these patients, how many of these also undergo chest CTA for clinical suspicion of pulmonary embolus and how many of these tests are positive? Furthermore, what is the correlation between duplex ultrasound results and chest CTA results?A retrospective chart review was conducted of total joint replacement patients in 2011 at a single institution. Inclusion criteria were adult patients who underwent a postoperative duplex ultrasonography for clinical suspicion of deep venous thrombosis (DVT). Demographic data, result of duplex scan, clinical indications for obtaining the duplex scan, and DVT prophylaxis used were recorded. Additionally, if a chest CTA was obtained for clinical suspicion for pulmonary embolus, results and clinical indication for obtaining the test were recorded. The rate of positive results for duplex ultrasonography and chest CTA was computed and correlated based on clinical indications.Two hundred ninety-five patients underwent duplex ultrasonography of which only 0.7% were positive for a DVT. One hundred three patients underwent a chest CTA for clinical suspicion of a pulmonary embolism (PE) of which 26 revealed a pulmonary embolus, none of which had a positive duplex ultrasound.Postoperative duplex scans have a low rate of positive results. A substantial number of patients with negative duplex results subsequently underwent chest CTA for clinical suspicion for which a pulmonary embolus was found, presumably resulting from a DVT despite negative duplex ultrasound result. A negative duplex ultrasonography should not rule out the presence of a DVT which can embolize to the lungs and thus should not preclude further workup when clinical suspicion exists for a pulmonary embolus.
