ReviewCombined use of neuraxial and general anesthesia during major abdominal procedures in neonates and infants.
With the advent of ultrasound and improvements in equipment, the applications of regional anesthesia in the pediatric population have continued to expand. Although frequently used for postoperative analgesia or as a means of avoiding general anesthesia in patients with comorbid conditions, the adjunctive use of regional anesthesia during general anesthesia may effectively decrease the intraoperative requirements for intravenous and volatile agents, thereby providing a more rapid awakening and earlier tracheal extubation. ⋯ Several authors have demonstrated the potential utility of combining a neuraxial technique (spinal or epidural anesthesia) with general anesthesia in neonates and infants undergoing intraabdominal procedures. We review the literature regarding the combined use of neuraxial and general anesthesia in neonates and infants during major abdominal surgery, discuss its potential applications in this population, and review the techniques of such practice.

Randomized Controlled TrialThe effect of fentanyl and clonidine on early postoperative negative behavior in children: a double-blind placebo controlled trial.
Early negative postoperative behavior (e-PONB) is common in children and manifests itself as emergence agitation (EA), emergence delirium (ED), and pain. The objective of this prospective double blind, randomized, placebo-controlled trial was to determine whether IV clonidine or IV fentanyl prior to surgery modifies e-PONB in children. ⋯ IV fentanyl before surgery but not IV clonidine modifies e-PONB in children undergoing lower abdominal surgery under general anesthesia supplemented with regional anesthesia. The use of fentanyl in this population was also associated with reduced pain scores after awakening but with significantly greater incidence of PONV.

Determination of optimum time for intravenous cannulation after induction with sevoflurane and nitrous oxide in children premedicated with midazolam.
It has been shown that early placement of an intravenous line in children administered sevoflurane anesthesia increased the incidence of laryngospasm and movement. However, the optimal time for safe cannulation after the loss of the eyelash reflex during the administration of sevoflurane and nitrous oxide is not known. ⋯ We recommend waiting 2 min for attempting intravenous placement following the loss of the eyelash reflex in children sedated with midazolam and receiving an inhalation induction with sevoflurane and nitrous oxide.

Randomized Controlled TrialProlonged perioperative infusion of low-dose ketamine does not alter opioid use after pediatric scoliosis surgery.
Opioid consumption after posterior spinal fusion is known to be high and often exceeds those reported in other major surgical procedures. A number of clinical trials provide evidence that the perioperative use of subanesthetic doses of ketamine reduces pain and opioid requirements in some surgical procedures, but the effect of prolonged perioperative low-dose ketamine infusion in patients undergoing posterior spinal fusion for pediatric scoliosis surgery is unknown. ⋯ These findings do not support the use of perioperative low-dose ketamine to decrease opioid use in children with scoliosis undergoing posterior spinal fusion.
