Randomized Controlled Trial Clinical TrialReducing the discomfort of lidocaine administration through pH buffering.
A prospective, double-blind study was undertaken to evaluate the effect of using a buffered lidocaine solution on the perception of pain experienced by a patient during its intradermal injection. ⋯ Buffering lidocaine significantly decreased the discomfort associated with its administration as a local anesthetic.

Interventional radiologic placement of Hohn central venous catheters: results and complications in 100 consecutive patients.
Hohn catheters are single- or double-lumen catheters used for intermediate-length central venous access. The authors report their technique, results, and long-term follow-up in a prospective study of their first 100 consecutive patients. ⋯ Technical success, complication, and long-term patency rates for the Hohn catheter are comparable to or better than those in most surgical series involving tunneled external catheters. The Hohn catheter is an excellent alternative for intermediate-length central venous access. Hohn subclavian catheter placement has become a standard part of the authors' interventional radiology service and is easily adaptable to all interventional practices.

Interventional radiologic placement of peripherally inserted central catheters.
This study examines the difference in success between bedside insertions of peripherally inserted central catheters (PICCs) performed by clinicians and fluoroscopically assisted insertions by cardiovascular/interventional (CV/I) radiologists. ⋯ Because of the far greater placement success achieved by CV/I radiologists, all PICCs are now inserted fluoroscopically. The devices complete favorably with surgically placed central catheters with regard to service interval, morbidity, and cost. Use of fluoroscopic techniques enables placement of these devices in virtually all patients, even those with seemingly no peripheral veins.

Randomized Controlled Trial Clinical TrialRandomized double-blind clinical trial of celiac plexus block for percutaneous biliary drainage.
This study was undertaken to determine the efficacy of celiac plexus block (CPB) as a method of providing analgesia for percutaneous biliary drainage (PBD). ⋯ This study indicates that CPB is not an effective means of providing additional visceral pain relief over and above that which can be accomplished with self-administered intravenous medication for patients who undergo PBD.
