BACKGROUND The use of ultrasound (US) in regional anaesthesia enables a reduction in the local anaesthetic volume. The present study aimed to determine the minimum effective volume (MEV(90)) of 0.5% bupivacaine with epinephrine for interscalene brachial plexus block (ISBPB). METHODS The volume of the anaesthetic was determined using a step-up/step-down(More)
OBJECTIVES Recently, evidence of reduction in mortality due to the use of volatile agents during cardiac surgery led to an increase in their use during cardiopulmonary bypass (CPB). Because this technique could be beneficial to patients, but might present several hazards to new users, the authors decided to perform a systematic review of the main problems(More)
BACKGROUND AND OBJECTIVES The use of the ultrasound to guide the puncture in peripheral nerve blocks has become increasingly more frequent. With the lower probability of promoting vascular damage the ultrasound has become an interesting tool in peripheral nerve blocks especially in patients in use of anticoagulants or with coagulopathies. The objective of(More)
BACKGROUND Renal failure affects the pharmacology of nondepolarizing neuromuscular blockers making recovery of neuromuscular function unpredictable. Sugammadex antagonises rocuronium-induced neuromuscular blockade by encapsulating rocuronium, creating a stable complex molecule that is mainly excreted by the kidneys. Previous studies suggest that sugammadex(More)
BACKGROUND AND OBJECTIVES Studies show the importance of monitoring neuromuscular function in preventing the residual block. However, most anesthesiologists in their daily practice base their evaluation of the recovery of neuromuscular function on clinical data. The aim of this study was to assess the degree of neuromuscular blockade in children undergoing(More)
BACKGROUND AND OBJECTIVES Rocuronium is an intermediate nondepolarizing neuromuscular blocker (NMB) with faster onset and indicated in situations requiring rapid tracheal intubation. Intravenous lidocaine is often used to decrease hemodynamic responses to tracheal intubation. The association of NMB to local anesthetics results in potentiation of NMB(More)
BACKGROUND AND OBJECTIVES The use of volatile anesthetics in cardiac surgery is not recent. Since the introduction of halothane in clinical practice, several cardiac surgery centers started to use these anesthetics constantly. CONTENT In the last years a great number of studies have shown that the volatile anesthetics have a protecting effect against(More)
INTRODUCTION Anesthesia induction through volatile agents is a well-established technique in several fields but not in adult patients undergoing cardiac surgery. Successful inhalation induction requires a poorly soluble, reasonably potent and minimally irritant agent, and the benefits associated to this technique include reduced incidence of hypothermia and(More)
BACKGROUND AND OBJECTIVES Additional neuromuscular blocker doses are in general needed during wall closing after abdominal surgeries. This study aimed at determining during partial pancuronium-induced neuromuscular block recovery, the effect of additional atracurium dose on spontaneous neuromuscular block recovery. METHODS Participated in this study 30(More)
BACKGROUND AND OBJECTIVES Developments in anesthesiology have improved safety indices. Several techniques and agents are used to control the hemodynamic response and minimize adverse effects triggered by surgical stimuli in patients undergoing cardiac procedures. CASE REPORT This is a 70 years old male patient, 1.74 m, 75 kg, ASA III, and NYHA II. The(More)
