Postoperative general medical ward admission following Chiari malformation decompression.

OBJECTIVE: Prior to 2019, the majority of patients at Children's Hospital Colorado were admitted to the pediatric intensive care unit (PICU) following Chiari malformation (CM) decompression surgery. This study sought to identify the safety and efficacy of postoperative general ward management for these patients. METHODS: After a retrospective baseline assessment of 150 patients, a quality improvement (QI) initiative was implemented, admitting medically noncomplex patients to the general ward postoperatively following CM decompression. Twenty-one medically noncomplex patients were treated during the QI intervention period. All patients were assessed for length of stay, narcotic use, time to ambulation, and postoperative complications. RESULTS: PICU admission rates postoperatively decreased from 92.6% to 9.5% after implementation of the QI initiative. The average hospital length of stay decreased from 3.4 to 2.6 days, total doses of narcotic administration decreased from 12.3 to 8.7, and time to ambulation decreased from 1.8 to 0.9 days. There were no major postoperative complications identified that were unsuitable for management on a conventional pediatric medical/surgical nursing unit. CONCLUSIONS: Medically noncomplex patients were safely admitted to the general ward postoperatively at Children's Hospital Colorado after decompression of CM. This approach afforded decreased length of stay, decreased narcotic use, and decreased time to ambulation, with no major postoperative complications.

Vascularized Pericranial Flap as a Method to Prevent Persistent Skull Defects After Craniectomy for Sagittal Synostosis.

ABSTRACT: Some cranial defects resulting from sagittal craniectomy for craniosynostosis never completely close and require cranioplasty. This study evaluates the results of 2 methods to minimize such defects: (1) trapezoidal craniectomy that is narrower posteriorly (2) vascularized pericranial flap that is sewn to the dura under a rectangular craniectomy.Children who underwent primary open sagittal craniectomy with biparietal morcellation (with/without frontal cranioplasty) for single-suture nonsyndromic sagittal synostosis from 2013 through 2018 were included. Children were excluded if there was a dural tear, if they had no 1-year follow-up, or if they had unmeasured and/or uncounted skull defects. Surgeries were divided into (1) standard craniectomy, (2) trapezoidal craniectomy, or (3) craniectomy with pericranial flap. Differences in percentage of children with defects and mean total defect area 1 year postsurgery were compared between the 3 groups.We reviewed 148 cases. After exclusions, 34 of 53 children (64%) who underwent standard craniectomy, 6 of 17 children (35%) who had pericranial flaps, and 5 of 11 children (46%) who underwent trapezoidal craniectomy had defects 1 year postsurgery. The percentage of children with defects (P = 0.0364) but not the defect area was significantly higher in the standard craniectomy than in the pericranial flap group. The percentage of subjects with defects was not significantly different between the standard and the trapezoidal craniectomy groups.Sewing a vascularized pericranial flap to the dura at the craniectomy site may protect against persistent bony defects after sagittal craniectomy for craniosynostosis. Longer follow-up is needed to determine if this technique leads to lower rates of cranioplasty.
