In conclusion, major complications after neuraxial techniques are rare but can be devastating to the patient and the anesthesiologist. Prevention and management begin during the preoperative visit with a careful evaluation of the patient's medical history and appropriate preoperative discussion of the risks and benefits of the available anesthetic techniques. Alternative anesthetic techniques, such as peripheral regional techniques or general anesthesia, should be considered for patients at increased risk for neurologic complications following neuraxial block. ⋯ Efforts should also be made to decrease neural injury in the operating room through careful patient positioning. Postoperatively, patients must be followed closely to detect potentially treatable sources of neurologic injury, including expanding spinal hematoma or epidural abscess, constrictive dressings, improperly applied casts, and increased pressure on neurologically vulnerable sites. New neurologic deficits should be evaluated promptly by a neurologist, or neurosurgeon, to document formally the patient's evolving neurologic status, arrange further testing or intervention, and provide long-term follow-up.

Ambulatory surgery is increasing at unprecedented rates with more complex procedures being performed. This article reviews the benefits of the use of regional anesthesia during ambulatory surgeries. Regional anesthesia, by putting the anesthetic at the surgical site, provides ideal conditions for ambulatory surgery and provides a smooth, predictable post-operative course.

Lower extremity nerve blocks have not become as popular as upper extremity blocks for anesthesia; however, the use of lower extremity nerve blocks will become more widespread, as teaching programs are now providing more regional anesthesia experiences for their trainees so that the anesthesia provider will have the familiarity to use these blocks. To increase the enthusiasm among our surgical colleagues, we must begin to use these blocks for surgery, and if the block must be supplemented with local anesthetic or a light general anesthetic, we must educate them that the block is not a failure but a success, as it will provide analgesia after surgery in a method of multimodal pain control. ⋯ Because the block may be placed in an induction room, there is no induction or emergence in the operating room. Patients may be discharged without the need for pain medications, thus lowering the incidence of nausea postoperatively and decreasing PACU and discharge times.

ReviewNew developments in epidural anesthesia and analgesia.
Several recent advances in epidural anesthesia and analgesia have been reviewed. Perhaps the most exciting area of anticipated future developments relates to the continued development of novel analgesic agents and new epidural delivery systems. There appears to be some movement toward an increased use of intrathecal or peripheral neural blockade techniques for some clinical situations where epidural anesthesia and analgesia have been previously used; however, the ability to provide anesthesia and analgesia to relatively large areas of the body with a single injection or continuous catheter technique without the associated risks of dural puncture and intrathecal catheter placement will continue to assure epidural anesthesia and analgesia techniques a prominent role in anesthesia and pain management.

The practice of administration of labor analgesia has undergone dramatic changes this decade. This is largely attributable to unparalleled interest in the field by many dedicated and capable investigators around the world. Through their efforts, this decade has witnessed the introduction of new techniques (pencil point needles, CSE, PCEA, ultradilute epidural regimens) that have permitted us to come closer than ever to realizing the goal of complete relief from the pain and suffering of labor while safeguarding the well-being of mother and child and minimizing effects on the labor process. Neuraxial anesthetic techniques and modern multimodal analgesic approaches to postoperative pain relief now minimize the effects of cesarean delivery on maternal satisfaction and participation in the birth process.
