Description of intervention(s) / exposure
In this study, cerebral palsy patients who applied to our hospital for BoNT-A administration between January 2008 and 2018 were retrospectively included. It was aimed to compare the different anesthesia types and functional results in patients who received repeated BoNT-A (2 units/0.1 ml) (Serial BoNT-A administration method intramuscular injection). A total of 3 doses were administered once every 6 months. Three types of anesthesia methods (intra venous midazolam 0.1 mg/kg, intravenous ketamine 0.5 mg/kg sedation analgesia, general anesthesia with laryngeal mask airway (LMA), general anesthesia with anesthesia mask) were applied to the patients during the procedures. Anesthesia applications were started approximately 5 minutes before the BoNT-A injection and stopped immediately after the injection. Side effects, recovery time and total operation time were compared.

Statistical methods / analysis
When the sampling error is ± 0.05 and the prevalence is 0.0036, the sample size is 53.32.
It is planned to use SPSS package program for statistical analysis. Following descriptive statistics, a comparison will be made between groups in terms of angles showing component placements (t test if the distribution is normal, or Mann Whitney U test if not). The groups will be divided into two subgroups according to the angle of the deformity; Again, comparisons will be made between these groups. Separate groups will be created according to the surgical approach applied and angles will be compared between groups. Depending on whether the distributions are normal or not, appropriate parametric or nonparametric tests will be used.

Summary
Brief summary
In this study, it was aimed to compare the functional outcomes and different anesthesia types applied in patients who received repeated BoNT-A. Serial BoNT-A is now a routine form of application in improving function and movement in children with cerebral palsy, which requires the repetitive anesthesia applications to be reliable and effective.

While repeated BoNT-A application in children with CP provides progress in motor steps, it can be applied safely and effectively under anesthesia. Sedation analgesia application provides easier recovery compared to general anesthesia with LMA and masks only in the first three applications. However, recovery time increases with 4 and more repeated applications as the number of applications increases.
