Preoperative comorbidities and relationship of comorbidities with postoperative complications in patients undergoing transurethral prostate resection.

Purpose: We retrospectively identified preoperative comorbidities and analyzed the relationship of the comorbidities to postoperative complications in patients treated with transurethral prostate resection.

Materials And Methods: We reviewed the surgical and clinical records of 1,878 patients who underwent transurethral prostate resection at a single university hospital between January 2006 and December 2009. Variables included preoperative comorbidities, intraoperative data and postoperative complications, including mortality.

Changes of dorsalis pedis artery flow pattern after caudal block in children: observational study using a duplex sonography.

Objective: To evaluate the changes of the flow velocity, the volume flow, and the diameter of dorsalis pedis artery using a duplex ultrasonography after caudal block with sevoflurane anesthesia in children.

Aim: To know the acute change in peripheral arterial flow patterns of sympathetically blocked lower limbs in anesthetized children.

Background: Caudal analgesia in combination with general anesthesia may affect the circulatory hemodynamics due to sympatholytic vasodilating effects.
