To compare the analgesic efficacy and plasma concentration of intramuscular (IM) versus epidural (EP) clonidine, 20 patients recovering from orthopedic or perineal surgery were randomly divided into two groups of ten. Clonidine (2 micrograms/kg) was administered epidurally in group 1 and intramuscularly in group 2. Analgesia was assessed using a visual(More)
The analgesic effect of extradural clonidine was evaluated in a double-blind study. In the recovery room, following orthopaedic or perineal surgery 20 ASA I and II patients were allocated randomly to two groups. The extradural clonidine (EC) group received clonidine 2 micrograms kg-1 in isotonic saline solution 15 micrograms ml-1. The extradural saline (ES)(More)
As suggested by experimental studies, systolic pressure variation (SPV), the difference between maximum and minimum values of systolic blood pressure after a single positive pressure breath, may be a fair indicator of left ventricular preload. SPV was quantified in 21 patients who had undergone abdominal aortic surgery and were sedated under mechanical(More)
This prospective study was conducted to describe the signs on transesophageal echocardiography (TEE) associated with traumatic aortic injury (TAI). Twenty-eight patients with TAI underwent TEE, and they were compared with a control group of 30 thoracic trauma patients without aortic injury. The TEE signs were classified as direct or indirect signs, and the(More)
In order to assess the effect of spinal clonidine on tourniquet pain, 30 patients scheduled to undergo orthopaedic surgery under spinal anaesthesia were allocated randomly to two groups. Patients in group I (n = 15) received 0.5% isobaric bupivacaine 15 mg plus isotonic saline 1 ml. Patients in group II (n = 15) received 0.5% bupivacaine 15 mg plus(More)
BACKGROUND Brain death may induce myocardial dysfunction, the mechanisms of which are not yet fully understood. Circulating cardiac troponin T is considered a highly sensitive and specific marker of myocardial cell injury. METHODS AND RESULTS We prospectively measured circulating cardiac troponin T in 100 brain-dead patients and measured the left(More)
Epidural clonidine produces postoperative analgesia in patients and potentiates opioid analgesia in animals. The aim of the current study was to assess the effect of epidural clonidine on the plasma concentrations and analgesic effect of fentanyl after epidural administration. Twenty ASA physical status 2 or 3 patients recovering from abdominal surgery were(More)
The effect of clonidine, an alpha 2 agonist, on sensory and motor blockade during spinal anesthesia was studied in 44 ASA physical status I II patients scheduled for orthopedic surgery. The patients were randomly allocated into three groups given 15 mg of 0.5% hyperbaric tetracaine (HT), within group I (N = 14) 1 ml isotonic saline, in group II (N = 15) 0.5(More)
The case of a 37-year old woman with no previous pathology who developed liver adenoma and focal nodular hyperplasia after taking various oral contraceptive (OC) combined preparations over 15 years is described. The woman was hospitalized after discovery of a mass in the right hypochondrium. Other clinical findings were normal. During laparotomy 2(More)
