Patient controlled analgesia with fentanyl or sufentanil in the postoperative period of knee ligament reconstruction: comparative study.
Epidural opioids, associated or not to local anesthetics, have been used for postoperative analgesia in continuous infusion and/or patient controlled boluses. The aim of this study was to compare postoperative analgesia provided by epidural fentanyl or sufentanil, in bolus or continuous infusion, in patients submitted to knee ligament reconstruction. ⋯ Epidural fentanyl or sufentanil in continuous epidural infusion and patient-controlled boluses in the doses used in this study have induced excellent postoperative analgesia. However, sufentanil caused more severe side effects than fentanyl.

Fresh-gas flow sequence at the start of low-flow anesthesia: clinical application of Maplesons theoretical study.
In a theoretical study, Mapleson using a multicompartmental pharmacokinetic model in a standard 40-year old and 70 kg man, has shown that with a fresh gas flow (FGF) initially equal to total pulmonary minute ventilation and then decreased to 1 L min(-1), and with fractional anesthetic administration (F(adm)) set to 3 MAC, the end fractional expired also expressed as alveolar (F(E')=F(A)) may reach 1 MAC in few minutes, according to the solubility of the inhaled agent. The purpose of this study was to clinically apply. ⋯ Results obtained confirm the clinical feasibility of Maplesons theoretical model. This way, a fast FA increase of the inhaled agent was achieved, which reached 1 MAC in 1 to 2 minutes and was maintained within this value with minor variations and low anesthetic consumption.
