Randomized Controlled Trial Clinical Trial
Effects of nilvadipine on the cardiovascular responses to tracheal intubation.
To evaluate the efficacy of nilvadipine given orally in attenuating the hypertensive response to laryngoscopy and intubation. ⋯ Oral administration of nilvadipine before induction of anesthesia is a simple and practical method for attenuating pressor response to laryngoscopy and tracheal intubation after standard elective induction under additional 1% enflurane-N2O anesthesia.

Randomized Controlled Trial Clinical Trial
Partial attenuation of the cardiovascular responses to tracheal intubation with oral nisoldipine.
To evaluate the efficacy and safety of nisoldipine given orally in attenuating the cardiovascular responses to laryngoscopy and tracheal intubation. ⋯ Oral administration of nisoldipine before induction of anesthesia is a simple, practical, and safe method for attenuating pressor response to laryngoscopy and tracheal intubation.

Review Case Reports
Propofol in patients susceptible to malignant hyperthermia: a case report and review of the literature.
Propofol is an intravenous (IV) drug recently introduced into the United States for induction and maintenance of anesthesia. In spite of extensive laboratory evaluation, it is not possible to predict all the potential side effects that might be associated with a new drug. Because malignant hyperthermia (MH) remains a serious and potentially life-threatening complication of anesthesia, all new anesthetic drugs should be considered potential triggering drugs until proven otherwise. We report the use of IV propofol for the induction and maintenance of general anesthesia in an MH patient and review the literature on this subject.

Unilateral phrenic nerve block is common after supraclavicular brachial plexus block techniques, although it is rarely symptomatic in patients without respiratory disease. A 24-weeks-pregnant woman was scheduled for a carpal tunnel release because of intractable pain. ⋯ Respiratory changes produced by pregnancy might compromise ventilatory reserve. Thus, we suggest avoiding supraclavicular approaches to brachial plexus block in pregnant women, since they may be as prone to developing respiratory embarrassment, secondary to phrenic block, as patients with pulmonary pathology.
