[Frequency of bacterial contamination of epidural and plexus catheters in postoperative analgesia].
There is little available information regarding contamination of perineural catheters. Incidence ranges from 5% to 57%, depending on the location of the catheter. The objective of this prospective study was to evaluate the incidence and predisposing factors of bacterial contamination of these catheters. ⋯ Although infection of perineural catheters is exceptional when they are placed for 2 or more days, contamination is very common. Epidemiological studies are required to evaluate the variables involved.

Randomized Controlled Trial[Paresthesia in various spinal anesthesia techniques for cesarean section].
To determine the incidence of paresthesia with different spinal puncture techniques using a 27-gauge Whitacre needle. ⋯ Combined epidural-subarachnoid puncture leads to a higher incidence of paresthesia in comparison with simple spinal puncture, probably because the lumbar puncture is performed on a dural sac that has been previously deformed due to the "tent effect" caused by the epidural needle. Fewer cases of paresthesia occur when the subarachnoid puncture is slow and steady and the introducer needle is withdrawn millimeters before it reaches the dural sac.

Randomized Controlled Trial Comparative Study[Cellular immune response to 3 anesthetic techniques for simple abdominal hysterectomy].
The effect of surgery and anesthesia on the immune response may have a significant effect on perioperative tumor surveillance. The aim of this study was to characterize the cellular immune response of patients undergoing simple abdominal hysterectomy under 3 types of anesthesia. ⋯ Combined general-epidural anesthesia seems to lower the counts of natural killer cells that are involved in tumor surveillance and destruction.

Review[Applications for bronchial blockers in thoracic surgery].
One-lung ventilation is commonly used to facilitate visualization of the field during thoracic surgery. New devices for performing this technique that have become available over the past 2 decades include the Univent bronchial blocker incorporated in a single-lumen tube, the Arndt endobronchial blocker, and the Cohen endobronchial blocker. ⋯ The literature search was performed on MEDLINE through PubMed using the keywords bronchial blockers and thoracic surgery. The search span started with 1982-the year the first modern bronchial blocker was described - and ended with February 2006.

Clinical Trial[Utility of monitoring with the PiCCO system during lung resection surgery].
To evaluate the practical utility of the PiCCO system for monitoring cardiac output and its derived variables during lung resection surgery. ⋯ The results suggest that using the PiCCO system during lung resection surgery is of limited utility, given that problems developed in relation to 53% of the catheters. This makes the technique unreliable in the event of its being required.
