BACKGROUND Acellular dermal matrix (ADM) is commonly used in staged breast reconstruction using tissue expanders (TEs). The literature on human ADM has reported variable outcomes, and there is a paucity of data for xenogenic sources of ADM. The aim of this study is to evaluate the early complications, risk factors and outcomes using SurgiMend™ in staged(More)
BACKGROUND Although the exact cause of dysphagia after cardiac operations is unknown, timely diagnosis is critical to avoid a devastating aspiration event. Accordingly, we sought to generate the risk of dysphagia in cardiac surgery (RODICS) score to identify patients at risk for its development after heart surgery. METHODS All adult heart surgery patients(More)
OBJECTIVE The purpose of this study was to derive and validate a risk score for pneumonia (PNA) after cardiac surgery. METHODS Adults undergoing cardiac surgery between 2005 and 2012 were identified in a single-institution database. The primary outcome was postoperative PNA. Patients were randomly assigned to training and validation sets in a 3:1 ratio. A(More)
In mechanically ventilated patients, head of bed (HOB) elevation above 30° decreases the risk of ventilator-associated pneumonia. The research team studied (a) compliance with proper HOB elevation in their cardiac surgical intensive care unit, (b) the accuracy of HOB angles recorded in the electronic medical record (EMR), and (c) the effect of bed type on(More)
OBJECTIVE We assessed the effectiveness of standardized protocols in decreasing postoperative mechanical ventilation time to <6 hours. METHODS In 2061 patients undergoing coronary bypass, the proportion extubated in <6 hours was calculated for 3 sequential time periods. During period 1 patients were weaned per baseline practices; during period 2, per a(More)
BACKGROUND We sought to quantify the effect of severe postoperative bleeding in hemodynamically stable patients following cardiac surgery. METHODS We reviewed the charts of all cardiac surgery patients operated on at our institution between 2010 and 2014. After excluding patients with tamponade or MAP <60, we propensity matched patients having chest tube(More)
BACKGROUND Harvesting the superior gluteal artery perforator (SGAP) flap involves dissection of vessels through the gluteal muscle, potentially compromising gait and ambulation. We compared patient-reported gait and ambulation problems between SGAP flap and deep inferior epigastric perforator (DIEP) flap reconstructions. METHODS Forty-three patients who(More)
BACKGROUND In specific patients, early postoperative nutrition mitigates malnutrition-related morbidity and mortality. The goal of this study was to develop and validate a prediction score designed to stratify patients immediately after cardiac surgery according to risk for nutrition support (NS). METHODS We identified adult cardiac surgery patients at(More)
BACKGROUND Computed tomographic angiography is often used for preoperative mapping. The authors aimed to systematically assess breast reconstruction outcomes after abdominally based free flaps planned with preoperative computed tomographic angiography versus Doppler ultrasonography. METHODS A search of the PubMed, EMBASE, and Scopus databases and an(More)
