Awake craniotomy with dexmedetomidine during resection of brain tumours located in eloquent regions

Abstract

Radical tumour resection can allow a satisfactory long-term outcome, a long life without tumour recurrence, and a shorter postoperative reconvalescence. Multiparameter intraoperative monitoring, including neuronal potentials, and clinical and psychological intraoperative evaluation of the patient, optimizes the postoperative neurological outcome [1][2][3]. However, radical tumour resection of eloquent brain tumours is associated with the risk of motor, speech, or memory disorders due to the possible injury of an eloquent brain network [4,5].

Reply to the commentary. Risks and tasks of awake craniotomy under conscious sedation

“…Dear Editor, We are responding to the questions raised by our colleagues from Warsaw (commentary by Surówka et al) [1] following the publication of our study "Awake craniotomy with dexmedetomidine during resection of brain tumours located in eloquent regions" [2]. We appreciate this discussion, as it could enhance the management of patients undergoing the awake craniotomy procedure.…”

Commentary on “Awake craniotomy with dexmedetomidine during resection of brain tumours located in eloquent regions”

“…Dear Editor, We read with great interest the recent study "Awake craniotomy with dexmedetomidine during resection of brain tumours located in eloquent regions" presented by Lechowicz-Głogowska et al [1] and the method used to perform awake craniotomy (AC) in the authors' centre. Although AC is considered as a gold standard of management during resection of intra-axial lesions in proximity to eloquent cortical and subcortical regions, until now a uniform consensus on anaesthetic management has not been established, as the authors rightly pointed out.…”
