Randomized Controlled Trial Comparative Study Clinical TrialSufentanil is preferable to etomidate during rapid-sequence anesthesia induction for aortocoronary bypass surgery.
To evaluate rapid-sequence anesthetic induction techniques for aortocoronary bypass grafting, 20 patients scheduled for elective surgery were randomly assigned to receive bolus injections of either etomidate, 0.4 mg/kg, intravenously (IV), or sufentanil, 5 micrograms/kg, IV, with succinylcholine, 1 mg/kg, IV. Patients in the two groups had similar demographic characteristics and baseline (preinduction) hemodynamic values. ⋯ No sufentanil patient demonstrated either ischemia or infarction. It is concluded that sufentanil-succinylcholine provides more stable hemodynamics and fewer ischemic myocardial events than etomidate-succinylcholine in patients undergoing myocardial revascularization surgery.

Randomized Controlled Trial Clinical Trial
Topical skin anesthesia for venous, subcutaneous drug reservoir and lumbar punctures in children.
A new topical anesthetic ointment (EMLA, "eutectic mixture of prilocaine and lidocaine was studied in a double-blind, placebo-controlled trial to evaluate its efficiency in alleviating pain associated with venous, subcutaneous drug reservoir and lumbar punctures in children. Pain intensity was scored by the children themselves, using a visual analogue scale in which 0 corresponded to absence of sensation and 10 to the worst imaginable painful sensation. ⋯ In lumbar punctures (14 children studied, 5.5 to 15.3 years of age), EMLA cream was again associated with less pain (1.9 +/- 1.9) than was placebo (5.6 +/- 3.0, P less than .01). It was concluded that the use of EMLA cream substantially reduces pain caused by venous, subcutaneous drug reservoir, and lumbar punctures in children and may therefore be offered to young patients, particularly those repeatedly submitted to such procedures.

Randomized Controlled Trial Clinical Trial
Isoproterenol is an effective marker of intravenous injection in laboring women.
The purpose of this randomized, double-blind study was to determine if isoproterenol 5 micrograms iv produces a consistent, noticeable tachycardia in healthy, laboring women. Maternal heart rate, fetal heart rate, and uterine contractions were continuously recorded and maternal blood pressure was measured every minute for 10 min before and after each patient received either normal saline (NS group; n = 10) or isoproterenol 5 micrograms (ISO group; n = 10) iv. The data-collecting investigator and a nurse palpating the patient's radial artery determined which solution they thought had been administered. ⋯ Diastolic and mean blood pressures did not change. No fetal distress occurred. Isoproterenol 5 micrograms is an effective marker of intravascular injection in laboring women; however, the safety and efficacy of epidural isoproterenol must be demonstrated in animals before isoproterenol can be incorporated in an epidural anesthesia test dose.
