Clinical Trial
Heart rate, heart rate variability, and blood pressure during perioperative stressor events in abdominal surgery.
To define the behavior of power spectral heart rate variability (PSHR) during potentially stressful events in the perioperative period, and relate it to changes in blood pressure (BP) and heart rate (HR). ⋯ On anesthetic induction, preoperative, but not intraoperative, spectral indices were predictive of BP changes. Power spectral analysis of HR may provide information about the autonomic state that is not evident from BP or HR. The HR power spectrum, in particular, indicated a striking autonomic imbalance immediately after the induction of anesthesia despite stable HR and BP. LFA and LFA/RFA ratio appeared to track sympathetic autonomic activation during abdominal surgical stimulation, but not during other perioperative stressor events.

Sarcoidosis, a rare multisystem disease, often occurs in women of childbearing age. The disease, which may be improved or exacerbated by pregnancy, presents unique considerations to the anesthesiologist. These considerations are illustrated by the case presented here of complicated sarcoidosis in a parturient who underwent cesarean section.

Randomized Controlled Trial Comparative Study Clinical Trial
Postoperative analgesia and intraoperative inhalational anesthetic requirements during umbilical herniorrhaphy in children: postincisional local infiltration versus preincisional caudal epidural block.
To determine the postoperative analgesic efficacy of, and the effects on, intraoperative inhalational anesthetic requirements of preincisional caudal epidural block versus postincisional infiltration of local anesthetic following umbilical herniorrhaphy in children. ⋯ Preincisional caudal epidural block is more effective in controlling pain following umbilical herniorrhaphy than is postincisional local infiltration.
