International Consensus Statement on Obstructive Sleep Apnea.

Background: Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA).

Methods: Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidence-based review with recommendations (EBR-R) formats.

A One-Year Institutional View of Resident Physician Burnout.

Objectives: This prospective study explores the prevalence, associated characteristics, and trajectory of burnout over one academic year in a multidisciplinary sample of resident physicians using a relatively new burnout survey instrument.

Methods: All residents from a U.S.

Morphine versus fentanyl patient-controlled analgesia for postoperative pain control in major hepatic resection surgeries including living liver donors: A retrospective study.

Background: Liver resection surgery results in significant postoperative pain. However, it is still not clear which opioids used by patient-controlled analgesia (PCA) provides the best pain control and results in the least side effect in a patient with impaired liver function. Our hypothesis was that fentanyl is a better choice than morphine as it is a potent analgesic that its elimination half-life does not depend on the hepatic uptake and metabolism.

Intraoperative Hypotension During Second Stage of Deep Brain Stimulator Placement: Same Day versus Different Day Procedures.

Background: We evaluated blood pressure management associated with implantable pulse generator (IPG) procedure on same day (SD) versus different day (DD) from deep brain stimulation (DBS) placement.

Methods: A retrospective chart review of 99 records for vasopressors given during IPG using a negative binomial regression model was performed. An association between SD versus DD, cumulative vasopressor dose, and minimum and maximum mean arterial pressure (MAP) were sought.

Factors predicting incremental administration of antihypertensive boluses during deep brain stimulator placement for Parkinson's disease.

Hypertension is common in deep brain stimulator (DBS) placement predisposing to intracranial hemorrhage. This retrospective review evaluates factors predicting incremental antihypertensive use intraoperatively. Medical records of Parkinson's disease (PD) patients undergoing DBS procedure between 2008-2011 were reviewed after Institutional Review Board approval.

Ultrasound-guided supraclavicular brachial plexus block: single versus triple injection technique for upper limb arteriovenous access surgery.

Background: Although ultrasound-guided supraclavicular block has a good success rate, it remains unclear whether multiple injections are superior to single injection (SI). We compared the sensory block success rate of SI versus triple injection (TI).

Methods: In this randomized double-blind study, 96 end-stage renal disease patients undergoing arteriovenous fistula creation or superficialization were randomly allocated to receive either SI or TI.

Some epidurographic explanations for incomplete epidural analgesia coverage in the absence of a catheter.

Study Objective: To determine the impact of the plica mediana dorsalis (PMD) on injected contrast media spread in the epidural space.

Design: Prospective interventional study.

Setting: Academic medical center.
