Comparative Study Clinical Trial
Comparison of epidural butamben to celiac plexus neurolytic block for the treatment of the pain of pancreatic cancer.
To compare pain relief in metastatic pancreatic cancer patients between neurolytic celiac plexus block (NCPB) and epidural 5% butamben suspension (EBS), a material-based delivery system of a local anesthetic that produces a long-lasting differential nerve block. ⋯ EBS appears to be a safe and effective alternative to NCPB in the treatment of pancreatic cancer pain.

Six patients with severe neuropathic pain caused by a Pancoast tumor were treated with the continuous administration of local anesthetics. These patients had not responded to any other treatment, including nonsteroidal anti-inflammatory drugs, opioids, dexamethasone, tricyclic antidepressants, anticonvulsants, ketamine, and transcutaneous electric nerve stimulation. ⋯ We conclude that neuropathic pain may be treated by local anesthetics administered through an axillary catheter placed in the brachial plexus. This technique is reversible and is preferable to destructive procedures such as cordotomy.

Clinical Trial
Penile prosthesis surgery under local penile block anaesthesia via the infrapubic space.
The aim of this study was to evaluate the effectiveness and patient tolerance to local penile block anaesthesia via the infrapubic space with penile prosthesis implantation. Local anaesthesia was administered using a 23-guage 1.5-inch needle. A 50-50 mixture of 0.5% bupivicaine (Marcaine) and 0.5% lidocaine (Xylocaine) without adrenaline was injected into the infrapubic space with additional subcutaneous penile ring infiltration at the level of the penile root. ⋯ In 148 (93%) patients, no booster sedation was needed; eight (5%) patients needed a boost of the pre-operative sedative during crural dilatation; three (1.8%) patients required general anaesthesia owing to insufficiently effective local anaesthesia and unexpectedly difficult dilatation. It is concluded that local anaesthesia was effective and safe to produce a pain-free procedure in 93% of cases. However, as the need for booster sedation or general anaesthesia exists, the procedure should be performed under monitored anaesthetic care and pre-operative evaluation should be performed as for general anaesthesia.

Postoperative analgesia for the ambulatory surgery patient is frequently inadequate. Continuous regional analgesia improves outcome and patient satisfaction in hospitalized patients. This paper describes the successful use of continuous regional analgesia following orthopedic surgery in the ambulatory setting.

We present a case of a rapid onset reversible phrenic nerve block following vertical infraclavicular blockade of the brachial plexus. Five minutes after injection of local anaesthetics the SpO2 fell to 80%. ⋯ The postoperative X-ray showed an elevated diaphragm of the ipsilateral side. After five hours oxygen supply could be terminated, an X-ray control the next day showed normal bilateral diaphragm position.
