44 of the patients in the AAA approach of Hansen et al. experienced arterial hypertension [33], but this refers only to the test phase. During the pinning, craniotomy and tumour resection there were only 5 patients with 10?0 increase in blood pressure. Additional analyses. The analysis of the composite outcome, including AC failure, intraoperative seizure and mortality was based on forty-one studies (S1 Fig) [10,17?6,28?0,32,34?41,43,46?2]. Of note, intraoperative seizure events, which concurrently led to an AC failure, were counted only once for this composite outcome. The total proportion was estimated to be 8 [95 CI: 6?1], with 8 [95 CI: 6?2] in the MAC group and 8 [95 CI: 5?2] in the SAS group. Logistic meta-regression did not show a difference of the event rate depending on the technique (MAC/ SAS). The OR was 0.9 [95 CI: 0.47?.76] and the residual heterogeneity I2 = 80 .PLOS ONE | DOI:10.1371/journal.pone.0156448 May 26,32 /Anaesthesia Management for Awake CraniotomyFig 4.
