Randomized Controlled TrialThe Effect of Adding Subarachnoid Epinephrine to Hyperbaric Bupivacaine and Morphine for Repeat Cesarean Delivery: A Double-Blind Prospective Randomized Control Trial.
Spinal anesthesia has become the most common type of anesthetic for cesarean delivery. The major limitation to spinal anesthesia is that the duration of the anesthetic may not be adequate in the event of a prolonged surgery. Some practitioners add epinephrine to hyperbaric bupivacaine to increase the duration, although its effect has not been fully studied. We therefore aimed to evaluate whether adding epinephrine to the spinal medication prolongs the duration of action of the resultant block in women presenting for repeat cesarean delivery. ⋯ In this single center, prospective, double-blind, randomized control trial, the addition of epinephrine 200 µg to hyperbaric bupivacaine and preservative-free morphine for repeat cesarean delivery prolonged the duration of the sensory blockade. Motor blockade was similarly prolonged and block quality may have been enhanced.

A Device for the Quantification of Oxygen Consumption and Caloric Expenditure in the Neonatal Range.
The accurate measurement of oxygen consumption (VO2) and energy expenditure (EE) may be helpful to optimize the treatment of critically ill patients. However, current techniques are limited in their ability to accurately quantify these end points in infants due to a low VO2, low tidal volume, and rapid respiratory rate. This study describes and validates a new device intended to perform in this size range. ⋯ This device can measure VO2, VCO2, and EE with sufficient accuracy for clinical decision-making within the neonatal and pediatric size range, including in the setting of tachypnea or hyperoxia.

Comparative StudyRates of Perioperative Respiratory Adverse Events Among Caucasian and African American Children Undergoing General Anesthesia.
Perioperative respiratory adverse events (PRAEs) account for the major cause of morbidity and mortality in children undergoing general anesthesia. In our institutional clinical practice, we suspected that African American children experienced untoward respiratory events more frequently than other racial groups. Identification of high-risk groups can guide decision making in the perioperative period, and aggressive optimization of specific care can enhance safety and improve outcomes. ⋯ In a multivariable logistic analysis, African American pediatric patients were shown to have significantly higher odds of PRAEs when compared with the Caucasian group.
