BACKGROUND The minimum local analgesic concentration (MLAC) has been defined as the median effective local analgesic concentration in a 20-ml volume for epidural analgesia in the first stage of labor. The aim of this study was to assess the relative analgesic potencies of epidural bupivacaine and ropivacaine by determining their respective minimum local(More)
BACKGROUND In this systematic review, we evaluated the evidence for seven strategies which have been proposed to minimize the incidence of epidural vein cannulation during lumbar epidural catheter placement in pregnant women. METHODS Multiple databases were searched to identify prospective, randomized, controlled trials between December 1966 and October(More)
BACKGROUND The minimum local analgesic concentration has been defined as the median effective local analgesic concentration (EC50) in a 20-ml volume for epidural analgesia in the first stage of labor. The aim of this study was to assess the relative analgesic potencies of epidural levobupivacaine and ropivacaine by determination of their respective minimum(More)
BACKGROUND Although obstetric patients are generally healthy, population risk is increasing because of increases in maternal age, obesity, and rates of multifetal pregnancies, and complications may occur in the immediate postoperative period. In this study, we sought to identify the current level of recovery care for obstetric patients in North American(More)
BACKGROUND Studies of urban parturient populations demonstrate increasing prevalence of obesity, which contributes to difficult epidural catheter placement. The aim of this study was to characterize the relationship between lumbar epidural space depth and body mass index in United States parturients from Michigan. METHODS We studied the records of 2009(More)
OBJECTIVE To establish the normal maternal range in healthy pregnant women for each component of the systemic inflammatory response syndrome (SIRS) criteria and compare these ranges with existing SIRS criteria. DATA SOURCES PubMed, Embase, and ClinicalTrials.gov databases were searched to identify studies of healthy parturients from the first trimester(More)
Hypertension is the most common medical disorder of pregnancy in the United States, affecting 6% to 8% of pregnant women. It is also a leading cause of maternal and fetal morbidity and mortality worldwide1; approximately 63,000 women die every year because of the maternal hypertensive syndromes preeclampsia and eclampsia.2 Hypertensive disorders also result(More)
BACKGROUND Maternal Mortality Surveillance has been conducted by the State of Michigan since 1950, and anesthesia-related maternal deaths were most recently reviewed for the years 1972-1984. METHODS Records for pregnancy-associated deaths between 1985 and 2003 were reviewed to identify 25 cases associated with a perioperative arrest or major anesthetic(More)
BACKGROUND The minimum local analgesic concentration (MLAC) has been defined as the median effective local analgesic concentration in a 20-ml volume for epidural analgesia in the first stage of labor. The aim of this study was to determine the local anesthetic-sparing efficacy of epidural sufentanil by its effect on the MLAC of bupivacaine. METHODS In(More)
