Randomized Controlled Trial Comparative Study Clinical Trial[Comparison of two 27-G-caliber needles for spinal anesthesia. Study of 1,555 patients].
The purpose of this study was to compare two 27-gauge anesthesia needles with different points (a Whitacre-type point and a Quincke-type point) and to assess the incidences of postdural puncture headache (PDPH), puncture difficulty and failed anesthesia. ⋯ When a 27-gauge Whitacre-point needle is used, fewer cases of PDPH develop and the puncture is easier to accomplish than when a Quincke-point needle is used. The number of failed anesthetic procedures is similar with both needles. Whitacre-point 27-gauge needles are preferable to Quincke-point 27-gauge needles.

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.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial[Ephedrine shortens the onset of action of rocuronium but not atracurium].
Ephedrine increases blood flow to muscles and may shorten the onset of action of rocuronium and atracurium. ⋯ Premeditation with 10 mg of ephedrine decreases the time until onset of action of rocuronium but does not affect the timing of atracurium.

Review[Non-therapeutic intraoperative hypothermia: prevention and treatment (part II)].
General and regional anesthesia alter the physiological mechanisms of thermoregulation, and unintentional intraoperative hypothermia develops during most surgical procedures that last more than 1 hour. Monitoring of central temperatures among other vital signs is advisable in such interventions in order to detect temperature changes and check the efficacy of measures to prevent or treat hypothermia. ⋯ The most often used are forced-air or warm water circulation devices. When large volumes of fluids must be infused intravenously, they must be warmed to body temperature to avoid heat loss.
