Randomized Controlled Trial Multicenter StudyPosttraumatic stress disorder in aware patients from the B-aware trial.
The long-term consequences of an awareness episode vary. Some patients do not have any long-term disability, whereas others develop psychological problems that may be severe and persistent. In this study, we compared the incidence of posttraumatic stress disorder (PTSD) in patients with and without confirmed awareness who were randomized in the B-Aware Trial. ⋯ PTSD was common and persistent in the confirmed awareness patients of the B-Aware Trial. Strategies to prevent awareness in patients under general anesthesia are justified.

Case ReportsPerioperative analgesia for forequarter amputation in a child: a dual paravertebral approach.
We describe the management of postoperative pain for a 10-year-old girl who underwent forequarter amputation for osteosarcoma of the left humerus. Because the brachial plexus itself was divided and resected during surgery, and the main body part innervated by the nerves from this plexus (the entire upper limb including the scapula and clavicle) was removed, providing analgesia via a brachial plexus block alone would probably not have provided adequate coverage. Because the tissue not resected with this surgery was innervated via the cervical and brachial plexuses and some upper thoracic nerve roots, we elected to combine a perioperative high continuous cervical paravertebral block at the C5 level with a continuous thoracic paravertebral block at the T2 level for postoperative analgesia. Our patient experienced excellent postoperative analgesia and required no narcotics during the immediate postoperative period.

Randomized Controlled Trial Comparative StudyA simple approach to the sciatic nerve that does not require geometric calculations or multiple landmarks.
Blockade of the sciatic nerve is necessary for complete analgesia of the lower extremity using peripheral nerve blocks. We identified the sciatic nerve in relation to the ischial tuberosity in fresh cadaver dissections as well as in patients to compare sciatic nerve blockade using the conventional approach versus our experimental approach. Specifically, we tested the hypothesis that in patients in the prone position, our novel approach (changing the point of needle insertion to 3 cm lateral from the ischial tuberosity) requires fewer needle passes and less time. ⋯ We describe a landmark that is more effective for identifying the location of the sciatic nerve than that used for the prone subgluteal approach.
