Safety of Open Cranial Vault Surgery for Single-Suture Craniosynostosis: A Case for the Multidisciplinary Team.

INTRODUCTION: Single Suture Craniosynostosis (SSC) occurs in 1 in 2,500 live births and is the most common type of craniosynostosis treated in most centers. Surgical treatment has evolved over the past century and open techniques are tailored to the specific suture type. Additionally, the concept of multi-disciplinary team care has proliferated and is becoming the standard of care for SSC. The combination of these evolutions, we believe, has improved the safety of cranial vault surgery for SSC. METHODS: A retrospective review of patients participating in the Infant Learning Project at Seattle Children's Hospital who underwent cranial vault surgery for treatment of SSC between 2002 and 2006 was performed. Pre-operative assessment, surgical techniques, anesthetic and intraoperative events and both intra-operative and post-operative adverse events were analyzed. RESULTS: Eighty eight patients fulfilled the inclusion criteria (42 sagittal, 23 metopic, 19 unicoronal, 4 lambdoid). Length of procedure varied (FOA 5.2 hrs, modified pi 2.5 hrs, total vault 4.9 hrs and switch cranioplasty 4.6 hrs), as did transfusion amount (FOA 385 mL, modified pi 216 mL, total vault 600 mL, switch cranioplasty 207 mL) although 99% of patients received a transfusion of some sort. There were no deaths and no major intraoperative complications. Minor events include; ET tube malposition (1), desaturation (1), acidosis (1), hypothermia (9), coagulopathy (2), Hct < 25 (55). Average hospital stay was 3.4 days with no major post-operative complications. One patient was readmitted to the ICU and 1 had a scalp hematoma, but no patients returned to the operating room within 6 months after surgery. DISCUSSION: The surgical treatment of SSC has evolved from lengthy, risky procedures to become almost routine at most craniofacial centers. Additionally, the care for patients with SSC has evolved from a single provider to a multidisciplinary team concept based around protocols for workup, delivery of anesthesia, streamlined surgical procedures and post-operative care and assessment. This evolution has given open cranial vault surgery for SSC an acceptable safety profile.

CT-guided percutaneous lung biopsy under general anesthesia: a pediatric case series and literature review.

We describe 14 consecutive children who received computed tomography-guided percutaneous lung biopsy (CT-PLB) under general anesthesia over an 18-month period at our institution. Pulmonary hemorrhage (occurring in 36%) and pneumothorax (29%) were the two most common complications; the overall complication rate was 64%. When complications did occur, immediate airway management was facilitated by the presence of an endotracheal tube (ETT). We conclude as follows: (i) CT-PLB in our series is associated with a high risk of both overall and severe complications; (ii) risk of complications is increased by both patient and procedure-related factors; (iii) airway management with ETT may be preferable should a complication arise; (iv) severe complications may necessitate ICU admission, which should be available before proceeding.

Duration of exposure to cranial vault surgery: associations with neurodevelopment among children with single-suture craniosynostosis.

OBJECTIVE: To evaluate associations between neurodevelopment and exposure to surgery and anesthetic agents in children with single-suture craniosynostosis (SSC). BACKGROUND: Young children with SSC have unexplained neurodevelopmental delays. The possible contributions of factors related to cranial vault surgery - including anesthesia - have not been previously examined. METHODS/MATERIALS: Two anesthesiologists reviewed the surgical records of 89 infants (70 had complete data). Primary exposures were duration of surgery and anesthesia and total duration of inhaled anesthesia (at age 6 months on average). Outcomes were the cognitive and motor scores from the Bayley Scales of Infant Development-II and language scores from the Preschool Language Scale, 3rd edition, given at age 36 months. Linear regression using robust standard error estimates was performed, adjusting for age at surgery and suture site. RESULTS: Anesthesia duration ranged from 155 to 547 min. For every 30-min increase in anesthesia duration, the estimated average decrease in developmental test scores ranged from 1.1 to 2.9 (P ranged from <0.001 to 0.30). Similar, but weaker findings were observed with surgery duration and total duration of inhaled anesthesia. Inverse relations between exposure amounts and neurodevelopment were stronger in children with nonsagittal synostosis. CONCLUSIONS: Average neurodevelopmental scores were lower among children experiencing longer surgeries and higher exposures to inhaled anesthesia. These associations may be due to anesthesia exposure, nonspecific effects of surgery, or unmeasured variables that correlate with surgery duration. Further study of potential causal mechanisms is warranted.
