Abstract Background: A patient's ability to move his/her fingers during hand surgery may be helpful to surgeons because it allows the effectiveness of the intervention evaluation and prediction of hand function in the postoperative period. The purpose of this case series is to demonstrate the efficacy of an ultrasound-guided peripheral nerve block technique to maintain the hand flexor and extensor muscles motor...
Abstract Background and objectives: To investigate, describe, and assess the phenomenon of “rebound pain” as a clinically relevant problem in anesthetic practice. Content: The phenomenon of “rebound pain” has been demonstrated and described as a very severe pain, which occurs after a peripheral nerve block resolution with the recovery of sensitivity. The incidence of rebound pain is unknown. Usually, it occurs ...
Abstract Introduction Randomized prospective study comparing two perivascular techniques with the perineural technique for ultrasound-guided axillary brachial plexus block (US-ABPB). The primary objective was to verify if these perivascular techniques are noninferior to the perineural technique. Method 240 patients were randomized to receive the techniques: below the artery (BA), around the artery (AA) or perin...
Abstract Introduction: The risk of systemic bupivacaine toxicity is a persistent problem, which makes its pharmacokinetic study fundamental for regional anesthesia safety. There is little evidence of its influence on plasma peak at different concentrations. The present study compares two bupivacaine concentrations to establish how the concentration affects this drug plasma peak in axillary brachial plexus block...
Abstract Background and objectives: The advent of ultrasound has brought many benefits to peripheral nerve blocks. It includes both safety and effectiveness, given the possibility of visualizing the neurovascular structures and the needle during the procedure. Despite these benefits, there is no consensus in the literature on the use of this technique in anticoagulated patients or with other coagulation disorde...
INTRODUCTION: The use of ultrasound in regional anesthesia allows reducing the dose of local anesthetic used for peripheral nerve block. The present study was performed to determine the minimum effective concentration (MEC90) of bupivacaine for axillary brachial plexus block. METHODS: Patients undergoing hand surgery were recruited. To estimate the MEC90, a sequential up-down biased coin method of allocation wa...
Justificativa e objetivo: o uso do ultrassom para acompanhar o correto posicionamento da agulha e a dispersão do anestésico local permitiu a redução do volume de anestésico local necessário para o bloqueio de nervos periféricos. Existem poucos trabalhos sobre o volume mínimo efetivo de anestésico local para o bloqueio do plexo braquial via axilar (BPVA). Este estudo foi conduzido com o objetivo de determinar o ...
JUSTIFICATIVA E OBJETIVOS: Hipertermia maligna (HM) é doença farmacogenética, com reação hipermetabólica anormal a anestésicos halogenados e/ou relaxantes musculares despolarizantes. Desde 1991 há um serviço hotline de atendimento telefônico para HM no Brasil, disponível 24 horas por dia, em São Paulo. Este artigo analisa a atividade do serviço brasileiro de hotline para HM em 2009. MÉTODOS: Análise prospectiva...
