ObjectiveThe aim of this study was to evaluate pre-, intra-, and postoperative anesthetic parameters in endoscopic strip craniectomy in order to improve anesthesiological care.Materials And MethodsThis is a retrospective patient cohort study of our first 121 patients treated by endoscopic strip craniectomy. Preoperative as well as intra- and postoperative anesthesiological and neurological parameters were analyzed. Furthermore, the need for intensive care unit admission, blood loss, and blood transfusion rate were measured.ResultsThe mean age of patients was 3.9 months (standard deviation = 1) at a mean weight of 6.3 kg (standard deviation = 1.3). Comorbidity was registered in 13 (11%) patients of which 5 had syndrome-related comorbidities. Mean duration of anesthesia was 131 minutes (standard deviation = 32) . One hundred and sixteen patients were induced by mask induction with sevoflurane and 5 patients were induced intravenously. In 10 patients, mild intraoperative hypothermia (between 35 and 36 degrees Celsius) occurred. The mean estimated blood loss was 35.4 mL (standard deviation = 28.9) and blood transfusion rate was 21.5%. Brief and small intraoperative oxygen saturation drops were common during this study. No indication for venous air embolism was found based on endtidal CO2 . Postoperative temperature above 38 degrees Celsius occurred 16 times and benign deviations in postoperative cardiopulmonary parameters occurred in 17 patients. Postoperative pain management was mainly established by paracetamol and low-dose morphine when necessary. No postoperative neurological symptoms were reported and no deaths occurred.ConclusionThese patients had a relatively short intraoperative course with stable vital parameters during surgery. We report a low incidence of significant venous air embolism, a blood transfusion rate of 21% and only minor perioperative disturbances in vital parameters.© 2018 The Authors.
