Low-dose sufentanil does not potentiate intrathecal morphine for perioperative analgesia after major colorectal surgery.

Purpose: Both intrathecal sufentanil (ITS) and intrathecal morphine (ITM) improve analgesia in obstetrical or cardiac procedures. From a pharmacokinetic standpoint, combining these two opioids may improve perioperative analgesia. We performed a prospective randomized double-blind study to compare the analgesic efficacy of ITM alone vs a mixture of a low dose of ITS plus ITM for perioperative pain relief in colorectal surgery.

Visual recovery after perinatal stroke evidenced by functional and diffusion MRI: case report.

Background: After perinatal brain injury, clinico-anatomic correlations of functional deficits and brain plasticity remain difficult to evaluate clinically in the young infant. Thus, new non-invasive methods capable of early functional diagnosis are needed in young infants.

Case Presentation: The visual system recovery in an infant with perinatal stroke is assessed by combining diffusion tensor imaging (DTI) and event-related functional MRI (ER-fMRI).
