STUDY OBJECTIVE To identify risk factors for life-threatening critical respiratory events occurring during parenteral analgesic therapy for acute postoperative pain. DESIGN Retrospective, observational, cohort study. SETTING University hospital. MEASUREMENTS The electronic records of patients with sudden-onset, life-threatening critical respiratory(More)
BACKGROUND Perioperative cardiopulmonary arrests are uncommon and little is known about rates and predictors of in-hospital survival. METHODS Using the Get With The Guidelines®-Resuscitation national in-hospital resuscitation registry, we identified all patients aged 18 yr or older who experienced an index, pulseless cardiac arrest in the operating room(More)
BACKGROUND Diagnosing obstructive sleep apnea (OSA) is clinically relevant because untreated OSA has been associated with increased morbidity and mortality. The STOP-Bang questionnaire is a validated screening tool for OSA. We conducted a systematic review and meta-analysis to determine the effectiveness of STOP-Bang for screening patients suspected of(More)
BACKGROUND Obstructive sleep apnea (OSA) is a largely underdiagnosed, common condition, which is important to diagnose preoperatively because it has implications for perioperative management. Our purpose in this study was to identify independent clinical predictors of a diagnosis of OSA in a general surgical population, develop a perioperative sleep apnea(More)
BACKGROUND Superiority of the modified Brice interview over quality assurance techniques in detecting intraoperative awareness with explicit recall has not been demonstrated definitively. METHODS We studied a single patient cohort to compare the detection of definite awareness using a single modified Brice interview (postoperative day 28-30) versus(More)
OBJECTIVE The purpose of this investigation was to examine the association of body mass index (BMI) category with short-term outcomes in minority surgical patients-a relationship that previously has not been well characterized. METHODS Data from the National Surgical Quality Improvement Program were used to calculate the BMI of minority patients(More)
BACKGROUND Carotid endarterectomy surgery can be performed under regional anaesthesia alone or under general anaesthesia. However, there are several types of regional block available and reported complication rates after superficial cervical plexus blocks are significantly lower than deep blocks. It is not known if subcutaneous and intermediate blocks are(More)
BACKGROUND Intraoperative awareness with explicit recall occurs in approximately 0.15% of all surgical cases. Efficacy trials based on the Bispectral Index® (BIS) monitor (Covidien, Boulder, CO) and anesthetic concentrations have focused on high-risk patients, but there are no effectiveness data applicable to an unselected surgical population. METHODS We(More)
