Spinal anesthesia in children: an educational review
Abstract
Despite the well-known benefits of spinal anesthesia (SA), this technique remains underutilized among pediatric anesthesiologists. According to the data from the Pediatric Regional Anesthesia Network, SA accounted for less than 5% of all neuraxial techniques. Some of the factors for underutilization of SA include: Limited duration, unfamiliarity with the technique in younger children, and surgeon preference for general anesthesia. The safe and successful use of SA in children involves recognition of anatomical and physiological differences between adults and children owing to differences in bony structures, spinal cord growth and cerebrospinal fluid physiology. Reports on successful use of SA in children for various surgeries have increased. This educational review summarizes what is known about SA in children, reviews the literature from the last decade and provides suggestions for development of SA in children. Technical considerations, role of ultrasound, guidance on dosing, physiological effects, unexplained aspects of the mechanism of action and combined caudal/SA are discussed.
