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.

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.
