Comparative StudySprotte needle for obstetric anesthesia: decreased incidence of post dural puncture headache.
Reports have emphasized the importance of spinal needle tip configuration in the development of post dural puncture headache (PDPH). ⋯ Our data indicate that the Sprotte spinal needle, with its non-cutting tip, results in a significantly lower (p less than 0.05) incidence of PDPH than Quincke cutting-tip needles of smaller gauge.

Venous levels of lidocaine and bupivacaine after midtarsal ankle block.
No data are available on blood levels of local anesthetics after ankle block. ⋯ The low peak level of local anesthesia and the prolonged analgesia confirmed the safety and efficacy of midtarsal ankle block for forefoot surgery and suggest that bupivacaine may be the local anesthetic agent of choice.

Case ReportsBilateral subdural hematomas after dural puncture: delayed diagnosis after false negative computed tomography scan without contrast.
BACKGROUND. Dural puncture secondary to spinal anesthesia or unintentional dural puncture during attempted epidural anesthesia can lead to headaches complicated by bilateral subdural hematomas. ⋯ CONCLUSION. Computed tomography scans with contrast media or magnetic resonance imaging may be necessary to diagnose bilateral subdural hematomas.

Comparative StudyThe effects of epinephrine on the anesthetic and hemodynamic properties of ropivacaine and bupivacaine after epidural administration in the dog.
Ropivacaine is a new local anesthetic that is chemically related to mepivacaine and bupivacaine. Previous laboratory studies have demonstrated that ropivacaine possesses an anesthetic profile similar to that of bupivacaine and has less arrhythmogenic potential. The current study was initiated to compare the hemodynamic and anesthetic effects of epidurally administered 0.75% bupivacaine and 1% ropivacaine, with and without epinephrine (1:200,000), in the dog. ⋯ The addition of epinephrine did not alter onset or duration of sensory or motor block in this animal model. Epinephrine reduced the average anesthetic blood concentration observed in both treatment groups at the various time intervals, but not the time to achieve the mean maximum blood level. No residual adverse effects were observed in any animal.

Temperature monitoring during epidural anesthesia for cesarean delivery.
Tympanic, rectal, and axillary temperatures were measured and compared in 12 ASA Physical Status I and II parturients during epidural anesthesia for cesarean delivery. Measurements were performed before (T0) and at 15 (T1), 30 (T2), 45 (T3), and 60 (T4) minutes after epidural anesthesia. At birth, rectal neonatal and maternal temperatures were measured. ⋯ The relative hypothermia observed in the newborns at birth after regional anesthesia was well correlated with the decrease in maternal temperature. A decrease in tympanic temperature of 1.4 degrees C developed during the course of epidural anesthesia for cesarean delivery. This decrease was underestimated by the measurement of rectal and axillary temperatures.
