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.

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.
