BACKGROUND Current knowledge of the risk for postoperative pulmonary complications (PPCs) rests on studies that narrowly selected patients and procedures. Hypothesizing that PPC occurrence could be predicted from a reduced set of perioperative variables, we aimed to develop a predictive index for a broad surgical population. METHODS Patients undergoing(More)
BACKGROUND AND OBJECTIVE Intraoperative Doppler ultrasound can be used to measure cardiac output by transoesophageal echocardiography. Recently, its reliability, when compared to the thermodilution technique, has been questioned. The purpose of this study was to compare intraoperative changes in cardiac output measured by echo-Doppler and by thermodilution(More)
New direct oral anticoagulant agents (DOAC) are currently licensed for thromboprophylaxis after hip and knee arthroplasty and for long-term prevention of thromboembolic events in non-valvular atrial fibrillation as well as treatment and secondary prophylaxis of venous thromboembolism. Some other medical indications are emerging. Thus, anaesthesiologists are(More)
BACKGROUND AND OBJECTIVES Damage to peripheral nerves provokes chronic neuropathic pain that lasts beyond the duration of the nerve injury. The presence of pain signs have been reported in areas other than those attributed to the injured nerve, i.e., in contralateral regions. We evaluated the presence, magnitude, and chronology of mechanical and cold(More)
BACKGROUND Reversal of the residual effect of rocuronium or cisatracurium by neostigmine may be slow and associated with side-effects. This randomized, safety-assessor-blinded study compared the efficacy of sugammadex, a selective relaxant binding agent for reversal of rocuronium-induced neuromuscular block, with that of neostigmine for reversal of(More)
STUDY OBJECTIVES To evaluate the intraoperative evolution of patients with COPD during lung resection and to test whether exercise testing could be helpful in the prediction of the intraoperative course. DESIGN Prospective study. SETTING University teaching hospital. PATIENTS Forty patients (mean [+/- SD] age, 65 +/- 9 years) with COPD (ie, FEV(1), 55(More)
Epidural anaesthesia using the loss of resistance to saline technique, without air, was successfully performed in a 65-year-old man scheduled for elective vascular surgery of the right leg. Epidural catheterisation was uneventful. Fifteen minutes after the initial dose of plain 0.5% bupivacaine, the patient experienced severe pain in his lower abdomen and(More)
Epidural analgesia is the most effective and innocuous technique for obstetrics. Pain relief is its main indication but maternal diseases that might be decompensated by labour and delivery are also accepted indications. Low doses of long-acting local anaesthetics alone or in combination with low doses of fentanyl or sufentanil provide good quality analgesia(More)
BACKGROUND Standard radiographs are primary means of evaluation of therapy-induced changes of the skeletal structure in patients with breast cancer metastatic to the bone, but objective quantitation has been difficult to standardize. MATERIALS AND METHODS Serial radiographs of therapy-induced changes in the structure of bone metastases secondary to breast(More)
Two homogeneous groups of 20 healthy women submitted to elective gynaecological surgery, who presented after anaesthesia with peripheral vasoconstriction and shivering, were included in a randomized, double-blind study. The first group received 10 mg ketanserin, a new pure antagonist of serotoninergic S2 receptors. The second group received 10 ml saline as(More)
