Predictors of Outcomes in 900 Alveolar Bone Grafts

Background: Significant discrepancies exist in the reported variables influencing alveolar bone graft outcomes. The purpose of this study was to evaluate graft success and identify outcome predictors in a large patient cohort using an objective cone beam computed tomography assessment tool. Methods: Consecutive patients with cleft lip/palate who underwent alveolar bone grafting by 1 surgeon were included. Predictor variables were age at graft, oronasal fistula, canine position, concurrent premaxillary osteotomy, size of cleft, presence of bony palatal bridge, history of failed graft, location of primary repair, and surgeon experience. The outcome variable was graft success, determined using a cone beam computed tomography assessment tool and defined as a score of 3 or 4 (out of 4) in the following domains: vertical bone level, labiopalatal thickness, and nasal piriform symmetry. Results: The sample included 900 alveolar cleft sites (median graft age, 9.9 years). The success rate was 94.6%. Presence of an erupted canine, large cleft defect, or premaxillary osteotomy were independent predictors of graft failure; presence of a bony palatal bridge was associated with graft success (P &lt; 0.05). Conclusions: Presence of an erupted canine, large bony defect, or premaxillary osteotomy increase the risk of failure, and a bony palatal bridge portends success. Age 12 years or older, visible oronasal fistula, history of failed graft, primary cleft repaired at outside institution, and surgeon experience were associated with higher graft failure, but were not independent predictors when controlling for covariates. Surgeons should be aware that these factors in combination increase the odds of graft failure. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.</p

Neurological outcome after extracorporeal cardiopulmonary resuscitation for in-hospital cardiac arrest: a systematic review and meta-analysis

BACKGROUND: In-hospital cardiac arrest (IHCA) is a major adverse event with a high mortality rate if not treated appropriately. Extracorporeal cardiopulmonary resuscitation (ECPR), as adjunct to conventional cardiopulmonary resuscitation (CCPR), is a promising technique for IHCA treatment. Evidence pertaining to neurological outcomes after ECPR is still scarce. METHODS: We performed a comprehensive systematic search of all studies up to December 20, 2019. Our primary outcome was neurological outcome after ECPR at any moment after hospital discharge, defined by the Cerebral Performance Category (CPC) score. A score of 1 or 2 was defined as favourable outcome. Our secondary outcome was post-discharge mortality. A fixed-effects meta-analysis was performed. RESULTS: Our search yielded 1215 results, of which 19 studies were included in this systematic review. The average survival rate was 30% (95% CI 28-33%, I2 = 0%, p = 0.24). In the surviving patients, the pooled percentage of favourable neurological outcome was 84% (95% CI 80-88%, I2 = 24%, p = 0.90). CONCLUSION: ECPR as treatment for in-hospital cardiac arrest is associated with a large proportion of patients with good neurological outcome. The large proportion of favourable outcome could potentially be explained by the selection of patients for treatment using ECPR. Moreover, survival is higher than described in the conventional CPR literature. As indications for ECPR might extend to older or more fragile patient populations in the future, research should focus on increasing survival, while maintaining optimal neurological outcome
