Brief Summary:
This study aims to investigate the association between hyperlactatemia and neurological disability, length-of-stay and mortality in patients who undergo tumorcraniotomy. The risk factors that induce lactat accumulation will also be explored.

Condition or disease Intervention/treatment
Hyperlactatemia Brain Tumor Surgery Anesthesia Other: Serum-lactate < 2,2 mmol/L Other: Serum-lactate >/= 2,2 mmol/L

Detailed Description:

Hyperlactatemia is a frequent occurrence in brain tumor surgery. The existing studies, however, are all retrospective, reporting varying effects on clinical outcome. One study reported new neurological deficitis, some found an association with extended hospital stay, while others found no association with outcome. It is therefore important to conduct a prospective study of hyperlactatemia in this patientgroup.

Participants in this study will follow the standard treatment protocol for tumorcraniotomy, aside from 2-3 additional, perioperative blodgas analyses and 2 standardized measurements of neurological disability.

Group/Cohort Intervention/treatment
Tumorcraniotomy patients Other: Serum-lactate < 2,2 mmol/L
Bloodgas analysis every hour from start surgery until recovery ward discharge

Other: Serum-lactate >/= 2,2 mmol/L
Bloodgas analysis every hour from start surgery until recovery ward discharge

Primary Outcome Measures :
  1. Neurological disability [ Time Frame: Change from baseline mRS at 30 days after surgery ]
    Modified Rankin Scale (Scoring 0-6, high scores meaning worse outcome)

Secondary Outcome Measures :
  1. Length of hospital stay [ Time Frame: 1 year ]
    In days from admission to discharge.

  2. Mortality [ Time Frame: After 30 days, 6 months and 5 years ]
