Case Reports[Continuous popliteal block with ropivacaine via a stimulant catheter for postoperative analgesia after foot surgery].
Three patients underwent foot surgery to correct hallux valgus and other toe deformities. Postoperative analgesia was provided by a sciatic nerve block in the popliteal fossa through a 21-gauge 64 mm needle and a 50 cm catheter connected to a nerve stimulator. ⋯ Hallux valgus surgery causes intense postoperative pain that can be prevented by a peripheral nerve block. A continuous popliteal block through a catheter equipped with a nerve stimulator is an easy technique that provides very good pain management after this type of surgery, with few undesirable side effects.

Review[Non-therapeutic intraoperative hypothermia: causes, complications, prevention, and treatment (part I)].
During the first hour of general anesthesia, a patient's body temperature can decrease between 1 and 1.5 degrees C; regional anesthesia also induces central hypothermia. Intraoperative hypothermia interferes with immunological function, particularly with the oxidative capacity of neutrophils. Cutaneous vasoconstriction occurs and blood flow is reduced in tissues subject to surgery. ⋯ Hypothermia increases the likelihood of shivering, and with enhanced central nervous system activation, there is increased cardiovascular morbidity. Currently, these effects can be attenuated or even avoided by applying various warming methods available. The efficacy and mechanisms of action of such methods are described in the second part of this review of the literature.

[Lateral popliteal block: a modification of anatomical references].
To study the efficacy of a lateral approach in performing a sciatic nerve block at the popliteal fossa using modified anatomical references: the intersection of the groove between the lateral vastus and biceps femoris muscles and the axis of the femur, which passes through the upper vertex of the popliteal fossa. ⋯ The proposed approach is easy to implement, involves no remarkable complications, and is particularly useful in patients who have difficulty taking a prone decubitus position.

Randomized Controlled Trial Comparative Study Clinical Trial[Analgesia and sedation in the subarachnoid anesthesia technique: comparative study between remifentanil and fentanyl/midazolam].
To assess the efficacy and safety of remifentanil in comparison with fentanyl-midazolam for analgesia and sedation during subarachnoid anesthesia. ⋯ Remifentanil is more effective for treating pain associated with a subarachnoid block and provides cardiovascular stability with a limited level of sedation per dose, but its use is associated with a high incidence of respiratory depression.
