Patterns of treatment of osteoradionecrosis with hyperbaric oxygen therapy in the United Kingdom.

We aimed to find out the number of patients with osteoradionecrosis (ORN) being treated by hyperbaric chambers in the UK during 2006-07, and the protocols that were being used. We did a telephone survey of 76 chambers to find out whether they treated patients with ORN, how many patients they treated in 2006-07, what chamber pressure they used, the duration of each session, and the total number of sessions/patient. A total of 25 chambers treated 273 patients with ORN in 2006-07; 10 were listed by the British Hyperbaric Association (BHA) and 15 were at multiple sclerosis (MS) centres. MS centres treated 23 (8%) of patients with ORN with a variable number of sessions of shorter duration and lower pressures than the chambers listed by the BHA. Most BHA chambers treated patients at 2.2 ATA for 90 min/session with 30 preoperative and 10 postoperative sessions/patient.

The duration of intrathecal bupivacaine mixed with lidocaine.

Abstract: Although spinal bupivacaine may have too long duration to be useful in the ambulatory setting, recent animal data suggest that lidocaine added to spinal bupivacaine may reduce the duration of bupivacaine spinal anesthesia. We explored whether lidocaine added...

Oxygen therapy in stroke: past, present, and future.

Abstract: Oxygen is frequently administered to patients with suspected stroke. However, the role of oxygen therapy in ischemic stroke remains controversial in light of the failure of three clinical trials of hyperbaric oxygen therapy to show efficacy, and the fear of...
