BACKGROUND AND OBJECTIVES Over the past 10 years, several studies have suggested that the addition of certain opiates to the local anesthetic used for brachial block may provide effective, long-lasting postoperative analgesia. One of these studies indicated that the agonist-antagonist, buprenorphine, added to bupivacaine provided a longer period of(More)
BACKGROUND AND OBJECTIVES Buprenorphine added to local anesthetic solutions for supraclavicular block was found to triple postoperative analgesia duration in a previous study when compared with local anesthetic block alone. That study, however, did not control for potentially confounding factors, such as the possibility that buprenorphine was affecting(More)
Brachial plexus blockade is the cornerstone of the peripheral nerve regional anesthesia practice of most anesthesiologists. As part of the American Society of Regional Anesthesia and Pain Medicine's commitment to providing intensive evidence-based education related to regional anesthesia and analgesia, this article is a complete update of our 2002(More)
Head injury is a major factor in the mortality of traumatized patients, accounting for about 50 percent of the resulting fatalities. Alcohol intoxication is frequently (25 to 50 percent) associated with head injuries. This study was undertaken to investigate the effects of alcohol on head trauma in a standardized animal model. Swiss Webster mice (25 ± 2 g)(More)
BACKGROUND A significant number of vascular injuries occur with the use of percutaneous diagnostic and therapeutic procedures. This study was done to indicate the types of these injuries and their management. METHODS Over a 30-month period, 55 patients required operation for vascular complications after percutaneous femoral procedures including infrarenal(More)
BACKGROUND AND OBJECTIVES Major nerves and vessels run alongside each other in a "neurovascular bundle" kept together by connective tissue that is often referred to by anatomists, surgeons, and anesthesiologists as the "sheath." Our goal was to macroscopically demonstrate the brachial plexus sheath in embalmed and fresh cadaver dissections. METHODS(More)
BACKGROUND Ankle blocks typically include the block of 5 nerves, the 4 branches that trace their origin back to the sciatic nerve plus the saphenous nerve (SaN). The sensory area of the SaN in the foot is variable. Based on our clinical experience, we decided to study the sensory distribution of the SaN in the foot and determine whether the block of this(More)
It is becoming increasingly evident that platelets play a significant role in the inflammatory process. Heterogeneity has been demonstrated among platelets, and evidence has been presented that the spleen retains the youngest and hemostatically most effective platelets. The present study was designed to determine what effect splenectomy, by removing a(More)
Prolonged anastomotic and needle hole bleeding from synthetic vascular prostheses is a common surgical problem in heparinized patients and in the patient with a coagulopathy. The relative effectiveness of various hemostatic agents has not previously been determined by controlled comparisons. In this study 6 mm polytetrafluoroethylene (PTFE) vascular(More)
