BACKGROUND: Postoperative pulmonary complications in orthopedic surgery patients have been associated with worse clinical outcomes. Identifying patients with respiratory risk factors requiring enhanced monitoring and management modifications is an important part of postoperative care. Patients with unanticipated respiratory decompensation requiring transfer to the intensive care unit (ICU) have not been studied in sufficient detail. METHODS: A retrospective case-control study of elective orthopedic surgery patients (knee, hip, shoulder, or spine, n = 51) who developed unanticipated respiratory failure (RF) necessitating transfer to the ICU over a 3-year period was conducted...

BACKGROUND: Ambulatory surgery plays an important role in pediatric anesthesia. However, it is difficult to predict which patients will experience complications. Age >80, ASA class 3 or 4, duration of surgery >3 h, and BMI 30-35 are independent predictors of unanticipated admission in adults. In this study, we retrospectively evaluate risk factors for unanticipated admission, following ambulatory surgery in children. METHODS: All ambulatory patients requiring unanticipated admission between 2005 and 2013 were compared to a random sample of patients not requiring admission in this case-control study...

BACKGROUND: The goal of elective orthopedic surgery is to return patients to their expected level of activity without an increased incidence of postoperative complications. The first step is identifying patient and/or surgical characteristics responsible for these complications. QUESTIONS/PURPOSES: This study sought to identify predictors of a step-up in medical care after non-ambulatory elective orthopedic surgery. METHODS: At a single specialty orthopedic hospital, we identified all in-hospital postoperative patients who were transferred to a higher level of medical care ((PACU) post-anesthesia care unit)...

The obstructive sleep apnea syndrome (OSAS) may affect children, especially those with dentofacial disharmonies. Dentofacial orthopedic (DFO) treatments carried out in those patients must take this condition into account and can, in selected cases, improve or even treat the OSAS. The goal of our work was to report our experience about DFO treatments of children affected by OSAS in the department of maxillofacial surgery of Femme-Mère-Enfant hospital of university hospitals of Lyon, France.

BACKGROUND CONTEXT: Recent studies have shown that prophylactic use of intrawound vancomycin in posterior instrumented spine surgery substantially decreases the incidence of wound infections requiring repeat surgery. Significant cost savings are thought to be associated with the use of vancomycin in this setting. PURPOSE: To elucidate cost savings associated with the use of intrawound vancomycin in posterior spinal surgeries using a budget-impact model. STUDY DESIGN: Retrospective cohort study...

BACKGROUND: Obstructive sleep apnea (OSA) may worsen postoperatively. The objective of this randomized open-label trial is to determine whether perioperative auto-titrated continuous positive airway pressure (APAP) treatment decreases postoperative apnea hypopnea index (AHI) and improves oxygenation in patients with moderate and severe OSA. METHODS: The consented patients with AHI of more than 15 events/h on preoperative polysomnography were randomized into the APAP or control group (receiving routine care)...

BACKGROUND: Systematic screening and treatment of sleep-disordered breathing (SDB) or obstructive sleep apnea (OSA) in presurgical patients would impose a significant cost burden; therefore, it is important to understand whether SDB is associated with worse postoperative outcomes. We sought to determine the impact of SDB on postoperative outcomes in patients undergoing four specific categories of elective surgery (orthopedic, prostate, abdominal, and cardiovascular). The primary outcomes were in-hospital death, total charges, and length of stay (LOS)...

BACKGROUND: Because perioperative complications of unrecognized obstructive sleep apnea (OSA) can be severe, many bariatric surgery programs routinely screen all patients. However, many obese non-bariatric surgery patients do not get screened. We wanted to evaluate the need for routine preoperative OSA screening. METHODS: Morbidly obese patients with a body mass index (BMI) > 40 kg/m(2) undergoing bariatric surgery--all screened for OSA--were compared to morbidly obese orthopedic lower extremity total joint replacements (TJR) patients--not screened for OSA...

BACKGROUND: It is unclear when it is safe to discharge patients with a diagnosis of Obstructive Sleep Apnea (OSA) after ambulatory surgical procedures due to concern for postoperative respiratory compromise and hypoxemia. Our OSA patients undergoing ambulatory-type orthopedic procedures are monitored overnight in the PACU, thus we reviewed patient records to determine incidence of complications. METHODS: Two hundred and six charts of patients with preoperative diagnosis of OSA based on ICD-9 codes were reviewed for outcomes including episodes of hypoxemia...

Treatment of osteosarcoma (OSA) of the proximal humerus poses many difficulties and challenges to the treating team. Between 1993 and 2000, we treated 11 patients (three women, eight men; age range, 17-74 years) suffering from OSA of the proximal humerus by 'composite': massive allografts and long humeral prosthesis. At presentation, 10 patients were at stage 2-B and one at stage 3-B of OSA. One patient presented with a pathologic fracture. All patients except patient No. 6, received preoperative chemotherapy followed by limb salvage surgery and postoperative chemotherapy...

We investigated the frequency of undiagnosed sleep apnea in patients scheduled for elective total joint arthroplasty. Two hundred fifty-four patients were assessed between September 1999 and May 2001. At intake, patients were given a standard systems review with the addition of targeted questions about sleep apnea. Ten patients reported symptoms consistent with undiagnosed obstructive sleep apnea (OSA). The identification of undiagnosed OSA is an issue for orthopedic practice because many patients referred to an arthroplasty service for hip and/or knee surgeries are obese...
