Randomized Controlled Trial Comparative Study Clinical Trial[Hemodynamic effects of levosimendan following cardiac surgery].
The hemodynamic effect of levosimendan was compared to that of dobutamine in a trial enrolling 30 adults undergoing scheduled cardiac surgery with cardiopulmonary bypass. Fifteen patients were randomly assigned to receive levosimendan in a single dose of 18 microg x kg(-1) followed in 15 to 20 minutes by start of infusion at a rate of 0.2 microg x kg(-1) min(-1) for 24 hours (levosimendan group). Another 15 randomized patients received dobutamine infused at a rate of 7.5 microg x kg(-1) min(-1). ⋯ We found that mean arterial pressure and both systemic and pulmonary vascular resistance decreased significantly in the levosimendan group (P < 0.05), but not in the dobutamine group. On the other hand, both heart rate and cardiac index increased in the levosimendan group only (P < 0.05). We conclude that levosimendan improves hemodynamic stability in patients who have undergone cardiac surgery and that it is a good alternative for treating postoperative low cardiac output syndrome.

A large part of the success of epidural anesthesia rests on correct identification of the epidural space. The last hundred years have seen the description of numerous techniques for locating the space in the most straightforward, effective, safe, and reliable manner. To evaluate the advantages and disadvantages of these approaches and the complications associated with each, we carried out a MEDLINE search using the following key words: "epidural analgesia," "epidural anesthesia," "epidural space," "identification," and "loss of resistance" (LOR). ⋯ LOR with air, with isotonic saline, or a combination of both were the techniques shown to be simplest and safest. With respect to safety, LOR with air led to the greatest number of complications (pneumocephalus, air embolism, insufficient analgesia, higher incidence of dural puncture, nerve root compression, subcutaneous emphysema). When a small air bubble is created inside the syringe, LOR with saline solution is reliable and teachable, as well as safe and effective.

Case Reports[Intubation with the GlideScope videolaryngoscope in a man with severe cervical spondylolisthesis].
We describe a new videolaryngoscopic device designed for use in cases of difficult airway. The device consists of a plastic blade with a video camera located halfway along its length. A mounted light source assembly means that bleeding ocurring in the airway will not obstruct the view. ⋯ We report the case of a 56-year-old man who underwent surgery for severe cervical spondylolisthesis. We describe a modified approach to managing the videolaryngoscope that facilitated maneuvering and intubation and that offers an effective alternative to techniques with other devices. The advantages and disadvantages reported in the literature are reviewed.

[Intrathecal baclofen for children with chronic pain related to severe spasticity: advantages of tunneling the catheter in the testing phase].
To document the effectiveness and safety of intrathecal baclofen administered through a tunneled catheter during a diagnostic procedure, prior to implantation of a subcutaneous pump, in children with chronic pain due to severe spasticity. ⋯ Performing a trial of increasing doses of intrathecal baclofen therapy in continuous perfusion through a tunneled catheter facilitated selection of patients for whom chronic administration of intrathecal baclofen is effective and free of complications.

Case Reports[Neuraxial hematoma after combined regional anesthesia: conservative resolution].
Epidural hematoma is a rare but serious neurological complication of neuraxial anesthesia. We report the case of a woman in whom this complication presented after knee replacement surgery under combined neuraxial anesthesia. No adverse events occurred during surgery. ⋯ Surgery was ruled out in favor of conservative treatment. Neurological symptoms resolved slowly over the following days and the patient was discharged partially recovered 51 days after surgery and recovery was complete within 6 postoperative months. We discuss the prevalence, etiology, and treatment of neuraxial hematoma related to local or regional anesthesia.
