Prevalence and predictors of myocardial ischemia by preoperative myocardial perfusion single photon emission computed tomography in patients undergoing noncardiac surgery.

Background: The prevalence and predictors of myocardial ischemia before noncardiac surgery are unknown. In addition the predictive value of myocardial perfusion single-photon emission computed tomography (SPECT) before noncardiac in individual patients is uncertain.

Objective: Evaluate the prevalence and predictors of myocardial ischemia before noncardiac surgery, and determine the postoperative cardiac outcome based on results of myocardial perfusion SPECT.

Ephedrine requirements during spinal anesthesia for cesarean delivery in Jordanian parturients: association with b2 adrenoceptor gene variants.

Background: Maternal hypotension after spinal anesthesia for cesarean delivery is common. Many studies performed on the b2-adrenoceptor (b2AR) gene variants and their association with vasopressor requirements during and after neuroaxial block have contradictory conclusions.

Objectives: The aim of the study was to evaluate the influence of the b2AR in codons 16 and 27 on the incidence of maternal hypotension and ephedrine consumption after spinal anesthesia for cesarean delivery in an Arab ethnic group.

Iatrogenic water intoxication in healthy parturient causing convulsions and fractured mandible.

We report a case of a mandibular dentoalveolar fracture caused by severe iatrogenic hyponatremia-induced grand mal seizure in a 31-year-old pregnant lady who underwent normal vaginal delivery. She had oxytocin augmentation of her labor, and the seizure happened in the immediate postpartum period. The seizure was thought to be because of severe hyponatremia and prompt management controlled the metabolic disorder.
