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.

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.
