Glass ampoules have been widely used in packaging injection drugs. Glass has important characteristics that allow it to be widely used in fabrication of recipients for drugs and other sterile substances. However, contamination of solutions with glass microparticles on breaking open glass ampoules, the presence of metals, percutaneous injury, and biological contamination justify the need of educational materials to orient the manipulation of ampoules. ⋯ Team training and information provided by the pharmaceutical industry on the use of ampoules are fundamental in the prophylaxis of accidents and contaminations. The search for safer materials to replace glass is also important.

Clinical evaluation of two Ke0 in the same pharmacokinetic propofol model: study on loss and recovery of consciousness.
The constant equilibrium between the plasma and effect site (ke0) is used by pharmacokinetic models to calculate a drug concentration in its site of action (Ce). It would be interesting if Ce of propofol was similar at loss and recovery of consciousness. The objective of this study was to evaluate the clinical performance of two different ke0 (fast = 1.21 min(-1), and slow = 0.26 min(-1)) in relation to Ce during loss and recovery of consciousness using Marsh pharmacokinetic model. ⋯ Clinically, the slow ke0 (0.26 min(-1)) incorporated in the Marsh pharmacokinetic model showed better performance than the fast ke0 (1.21 min(-1)), since the calculated concentration of propofol at the effect site on loss and recovery of consciousness was similar.

Ross procedure is one of the surgical procedures for correction of severe congenital aortic insufficiency. Intraoperative transesophageal echocardiography is essential for optimal surgical evaluation. Furthermore, it is able to assess the blood volume profile and the need for administration of vasoactive drugs during surgery. ⋯ Ross procedure is one of the techniques for correction of congenital aortic insufficiency in which transesophageal echocardiography guides the surgeon precisely on the physiological and anatomical status of vascular grafts.

Case Reports[Post-dural headache with seven months duration: case report].
Post-dural puncture headache is a possible and expected complication in a small percentage of cases after spinal anesthesia. The objective of the current report was to describe the therapeutic conduct in a case of post-dural puncture headache with seven months of evolution. ⋯ This case demonstrated that the epidural blood patch was effective in the treatment of chronic post-dural puncture headache in a case with seven-month evolution.

Randomized Controlled Trial Comparative Study[Postoperative analgesia: comparing continuous epidural catheter infusion of local anesthetic and opioid and continuous wound catheter infusion of local anesthetic].
Continuous wound infusion has been investigated as a method of postoperative pain control and its efficacy has been demonstrated when compared to saline infusion. The objective of this study was to compare the quality of postoperative analgesia, the use of opioids as rescue analgesia, patient satisfaction, and the incidence of complications between epidural catheter infusion of local anesthetic and opioids and continuous wound infusion of local anesthetic. ⋯ Postoperative analgesia with opioids and local anesthetics via PCEA was superior to the patient-controlled local anesthetic infusion into surgical wound. The incidence of side effects was similar in both groups.
