Randomized Controlled Trial
Effect of timing of fluid bolus on reduction of spinal-induced hypotension in patients undergoing elective cesarean delivery.
Spinal-induced hypotension remains the most common complication associated with spinal anesthesia for cesarean delivery. Recent evidence indicates that a 20-mL/kg bolus via pressurized infusion system administered at the time of subarachnoid block (SAB) (coload) may provide better prophylaxis than the traditional administration of a 20-mL/kg crystalloid infusion (preload) approximately 20 minutes before SAB; however, this method raises some concerns. We hypothesized that administering half of the fluid bolus (10 mL/kg) before and half immediately following injection of the SAB would provide benefit. ⋯ No differences in neonatal outcomes were noted between groups. Maternal vital signs were not significantly different between groups; hypotension was treated as it occurred. We recommend replacing standardized prophylactic crystalloid fluid administration with the preload/coload method described herein.

Review Case Reports
Anesthetic considerations for the patient with hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome).
Hereditary hemorrhagic telangiectasia (HHT), Osler-Weber-Rendu Syndrome, is an uncommon disease but may be present in many people who remain undiagnosed. It is an autosomal dominant disorder characterized by multiple arteriovenous malformations (AVMs) and telangiectases that affect multiple organ systems. Hereditary hemorrhagic telangiectasia patients have a propensity for bleeding, especially from the oropharynx, nasopharynx and gastrointestinal tract, as well as from rupture of AVMs of other organ systems. Anesthetic care of patients with HHT involves very specific interventions with regard to control of bleeding, maintaining adequate oxygenation, and balancing hemodynamic values to optimize perfusion without compromising anesthetic depth.

Patients are admitted for surgery while taking a wide array of medications, and nurse anesthetists must evaluate their effectiveness and compatibility with anesthesia. Anesthetists must be familiar with the basic pharmacology of each drug and the potential adverse effects and possible drug interactions that may occur when anesthetic drugs are administered. If a medication requires discontinuation, we must ensure that the patient's disease remains controlled throughout the perioperative period. ⋯ Most medications taken for minor disorders that do not have systemic effects can be safely continued without incident. Some medications may require discontinuation or temporary alteration of the dosing schedule to avoid problems in the perioperative period. This course reviews the current literature regarding the anesthetic management of several commonly encountered drug classes.
