Spinal anesthesia in infants: recent developments.
OBJECTIVE
Spinal anesthesia has long been described as a well-tolerated and effective means of providing anesthesia for infants undergoing lower abdominal surgery. Now, spinal anesthetics are being used for an increasing variety of surgeries previously believed to require a general anesthetic. This, along with increasing concerns over the neurocognitive effects of general anesthetics on developing brains, suggests that further exploration into this technique and its effects is essential.


RESULTS
Exposure to spinal anesthesia in infancy has not shown the same suggestions of neurocognitive detriment as those resulting from general anesthesia. Ultrasound guidance has enhanced spinal technique by providing real-time guidance into the intrathecal space and confirming medication administration location, as well as helping avoid adverse outcomes by identifying aberrant anatomy. Spinal anesthesia provides benefits over general anesthesia, including cardiorespiratory stability, shorter postoperative recovery, and faster return of gastrointestinal function.


CONCLUSIONS
Early findings of spinal anesthesia exposure in infancy have shown it to have no independent effect on neurocognitive delay as well as to provide sound cardiorespiratory stability. With safer means of administering a spinal anesthetic, such as with ultrasound guidance, it is a readily available and desirable tool for those providing anesthesia to infants.
