To evaluate the clinical use of a new ECG-guided central venous catheter with regard to positioning in the superior vena cava (SVC). ⋯ Use of this wire-conducted intravascular ECG signal is a reliable tool for positioning the central venous catheter via various insertion sites. The technique proved to be an inexpensive, easy, and clear method. When a p-atriale is seen, uncomplicated insertions do not require radiologic guidance to control catheter tip position.

Randomized Controlled Trial Comparative Study Clinical Trial
Pretreatment with sedative-hypnotics, but not with nondepolarizing muscle relaxants, attenuates alfentanil-induced muscle rigidity.
To evaluate and compare the efficacy of various pretreatment agents to attenuate or prevent opioid-induced muscle rigidity using a well-established, previously described clinical protocol. ⋯ This study suggests that benzodiazepine pretreatment is frequently, but not always, effective in preventing opioid-induced muscle rigidity.

Review Case Reports
Administration of high-dose aprotinin during nonprimary cardiovascular surgery: case reports and review of the literature.
The perioperative management of two patients undergoing complex "redo" cardiac surgical procedures are presented. The management of both patients included the prophylactic administration of aprotinin via a "compassionate use" protocol. ⋯ In late December 1993, the Food and Drug Administration approved aprotinin for administration to cardiac surgical patients considered at high risk for post-cardiopulmonary bypass coagulopathies. Indications for the administration of aprotinin, as well as a brief review of the literature relating to the perioperative administration of aprotinin, are included.
