To facilitate electrocardiography (ECG)-guided central venous catheter placement by observing the shape and size of the P wave at specific locations of a central venous catheter (CVC) tip. ⋯ During ECG-guided central venous catheterization, the tallest peaked P wave may be used to place the CVC tip at the SVC/RA junction, the normally-shaped P wave identifies the mid to upper SVC, and biphasic P waves identify RA localization.

Mivacurium-induced neuromuscular block in adult patients suffering from Charcot-Marie-Tooth disease.
The response to non-depolarizing neuromuscular blocking drugs is variable in patients with Charcot-Marie-Tooth (CMT) disease. We speculated that CMT involvement of the monitored muscle may be partially responsible for this inconsistency. We therefore investigated the response to a standard dose of mivacurium simultaneously assessed at adductor pollicis (AP) and orbicularis oculi (OO) muscles in five patients with CMT. ⋯ The onset and recovery characteristics associated with mivacurium-induced neuromuscular block were similar at the AP and OO muscle groups. A near normal response to mivacurium was observed in this small series of patients with CMT disease.

Comparative Study
Analgesic effects of systemic midazolam: comparison with intrathecal administration.
Midazolam has antinociceptive effects when administered intrathecally, while its effects associated with systemic administration remain controversial. In the present study, the antinociceptive properties of systemically vs intrathecally administered midazolam were investigated in a rat model of thermal and inflammatory pain. ⋯ Systemically administered midazolam induced antinociception for inflammatory pain only, while intrathecal administration elicited antinociceptive effects on both acute thermal and inflammatory-induced pain.

To establish Canadian guidelines for training in adult perioperative transesophageal echocardiography (TEE). ⋯ The Canadian guidelines for training in adult perioperative TEE reflect the unique Canadian practice profile in perioperative TEE and address the training requirements to obtain expertise in this field.
