PURPOSE The purpose of this randomized control trial was to determine the performance of a novel rule-based adaptive closed-loop system for propofol administration using the bispectral index (BIS(R)) and to compare the system's performance with manual administration. The effectiveness of the closed-loop system to maintain BIS close to a target of 45 was(More)
BACKGROUND This prospective, randomized, observer-blinded study compared ultrasound-guided supraclavicular (SCB), infraclavicular (ICB), and axillary (AXB) brachial plexus blocks for upper extremity surgery of the elbow, forearm, wrist, and hand. METHODS One hundred twenty patients were randomly allocated to receive an ultrasound-guided SCB (n = 40), ICB(More)
BACKGROUND Volatile anesthetics provide myocardial protection during cardiac surgery. Sevoflurane and desflurane are both efficient agents that allow immediate extubation after off-pump coronary artery bypass grafting (OPCABG). This study compared the incidence of arrhythmias after OPCABG with the two agents. MATERIALS AND METHODS Forty patients(More)
BACKGROUND AND OBJECTIVES This prospective, randomized, observer-blinded study compared single- and double-injection, ultrasound-guided supraclavicular brachial plexus block for upper extremity surgery. METHODS Ninety-two patients were randomly allocated to receive a single-injection (n = 46) or double-injection (n = 46), ultrasound-guided supraclavicular(More)

BACKGROUND A recent study showed that the removal of a bladder catheter is safe in presence of thoracic epidural analgesia (TEA). However, the ability to void satisfactorily can be affected. The aim of this investigation is to determine whether patients with TEA are able to recover the micturition process. METHODS On the morning after the surgery patients(More)
BACKGROUND The objective of this prospective study is to determine cognitive dysfunction after thoracic surgery. METHODS Seventy-six patients undergoing thoracic surgery with single-lung ventilation (SLV) of an expected duration of >45 min were enrolled. Monitoring consisted of standard clinical parameters and absolute oximetry (S(ct)O(2)). The(More)
BACKGROUND AND OBJECTIVES It is common practice to catheterize the bladder in the presence of epidural analgesia and to leave the bladder catheter in situ to avoid postoperative urinary retention. However, bladder catheterization carries the risk for urinary tract infection (UTI). The objective of this randomized control trial was to assess whether the(More)
Editor—Cerebral oximetry has become a standard monitoring in cardiac surgery and some studies have shown its usefulness in non-cardiac surgery. 2 In the future, it may become widely used for routine monitoring. There are two different technologies used, absolute and relative oximetry. Absolute oximetry uses fibreoptic laser light of four different(More)
BACKGROUND In this pilot study, we tested a novel automatic anesthesia system for closed-loop administration of IV anesthesia drugs for cardiac surgical procedures with cardiopulmonary bypass. This anesthesia drug delivery robot integrates all 3 components of general anesthesia: hypnosis, analgesia, and muscle relaxation. METHODS Twenty patients scheduled(More)
