Risk Factors of Cai et al for Extubation Failure Following an Infratentorial Craniotomy

 

Patient selection: age > 18 years old, infratentorial craniotomy for tumor resection

 

Outcome: extubation failure

 

Risk factors for extubation failure from multiple logistic regression analysis:

(1) tumor size >= 30 mm

(2) past history of craniotomy (previous)

(3) tumor in the brain stem or compressing the brain stem

(4) preoperative lower cranial nerve dysfunction

(5) large blood pressure change during the operation (based on difference between the highest and lowest record mean arterial blood pressure)

 

where:

• The maximum blood pressure change in patients who were successfuly extubated ranged from 30 to 50 mm Hg. Patients who failed extubation had a maximum blood pressure change that ranged from 36 to 57 mm Hg. For the implementation will use > 50 mm Hg.
