Randomized Controlled Trial Clinical Trial[Usefulness of tranexamic acid in cranial remodeling surgery].
To assess the usefulness of tranexamic acid (TA) in pediatric cranial remodeling surgery, by analyzing its effects on bleeding and transfusion requirements, number of days of cranial drainage required, and time spent in the postoperative recovery unit. ⋯ TA can reduce perioperative bleeding in the context of pediatric cranial remodeling surgery. TA-treated patients have less need of transfusion and this may reduce the rate of related complications as well a make care more efficient.

Review[Gastrointestinal tonometry: a new tool for the anesthesiologist].
Intestinal hypoperfusion is among the factors implicated in sepsis and multiorgan failure. Splanchnic blood flow may be sacrificed to maintain supply to vital organs, even when hemodynamic alterations are minor. The sensitivity of invasive hemodynamic monitoring for detecting intestinal hypoperfusion is low. ⋯ We review the pathophysiology of ischemic intestinal lesions, the basis for gastrointestinal tonometry, and the method. Finally we discuss clinical applications (early diagnosis of ischemic colitis and ischemia of the flap after esophageal reconstruction, weaning from mechanical ventilation, abdominal compartment syndrome, liver transplant, heart surgery, prognostic factors and care of the critically ill patient). An adequate understanding of this monitoring technique and management of information it provides can give an early warning of the intestinal hypoperfusion that precedes other serious systemic complications.

Case Reports[3 cases of sedation and analgesia using propofol and remifentanil for labor].
Three women in labor for whom epidural analgesia was contraindicated--2 with sepsis (pylonephritis and chorioamnionitis) and 1 with sacral agenesia--were provided intravenous analgesia with propofol (0.4-1.2 mg/kg/h) and remifentanil (0.033-0.1 microgram/kg/min plus boluses of 20 micrograms controlled by the patient) with oxygen supplementation. Heart rate, noninvasive blood pressure, maternal oxygen saturation and fetal heart rate were monitored. Maternal satisfaction, quality of analgesia, maternal side effects (sedation, depression, breathing, muscle rigidity, nausea, and vomiting) and fetal side effects (heart rate variability and Apgar score) were evaluated. We conclude that in cases where epidural analgesia is contraindicated, intravenous perfusion of low doses of propofol and remifentanil can provide a valid alternative for analgesia during labor.
