Randomized Controlled Trial Clinical TrialProlonged placement of spinal catheters does not prevent postdural puncture headache.
To determine whether leaving an intrathecal catheter in place in the postoperative period prevents postdural puncture headache (PDPH). ⋯ Leaving the intrathecal catheter in place in the postoperative period for 12 to 24 hours does not prevent PDPH.

Randomized Controlled Trial Clinical TrialThe effect of continuous interscalene brachial plexus block with 0.125% bupivacaine plus fentanyl on diaphragmatic motility and ventilatory function.
Continuous interscalene brachial plexus block with 0.25% bupivacaine decreases diaphragmatic motility and ventilatory function. The author studied the effects of 0.125% bupivacaine with and without fentanyl. ⋯ Use of 0.125% bupivacaine for continuous interscalene block did not prevent a deterioration of diaphragmatic motility and ventilatory function. Co-infusion of fentanyl did not significantly potentiate the block.

Complications during spinal anesthesia for cesarean delivery: a clinical report of one year's experience.
To evaluate the incidence and causes of complications associated with spinal anesthesia for cesarean delivery. ⋯ Spinal anesthesia proved to be a safe, reliable, and rapid method of anesthesia for cesarean delivery, but, in view of a high incidence of minor complications, careful patient monitoring during spinal anesthesia is necessary to make the outcome optimal for mother and fetus.

Are anesthesia residency programs failing regional anesthesia? The past, present, and future.
A survey of anesthesia training programs in 1980 reported the use of a regional anesthetic technique in 21.3% of cases. Since that time, numerous changes have occurred in anesthesia residency programs. This survey was conducted to assess the impact these changes have had on the use and teaching of regional anesthetic techniques in residency training programs. ⋯ Some training programs continue to fail to provide adequate regional anesthesia exposure to train residents fully in these techniques, despite the overall increased use of regional anesthesia.

Pulse oximeter waveforms from the finger and toe during lumbar epidural anesthesia.
To determine whether lumbar epidural anesthesia affects pulse oximeter signals in the upper or lower extremity, 13 ASA I patients were studied. ⋯ More reliable pulse oximeter signals may be obtained from the toe than the finger during lumbar epidural anesthesia. Furthermore, the increase in the pulse amplitude from the toe may aid in the early detection of successful epidural block.
