Abstract
Objectives: To evaluate changes of Jugular bulb oxygen saturation (SjvO2) during surgery for severe head injured patients. Methods: A prospective study was conducted with 50 severe head injured patients undergoing craniotomy surgery. Preoperative SjvO2 in jugular bulb was measured after anesthesia induction by a catheter connecting to CeVOX monitor. SjvO2 was observed continuously during sugery and recorded at different phrases: before surgery (T1), after craniotomy (T2), after durotomy (T3), after removing hematoma (T4) and in 30 minutes after sugery (T5). Main Results: SjvO2 was in the normal range in 52% of patients, reduced in 32% and increased in 16% of patients. SjvO2 increased significantly during sugery, especially after craniotomy and durotomy compared to preoperative phrase (69.1±13.2% and 70.3±13.1% vs. 61.8±15.6%, p<0.05). SjvO2 did not change significantly in the patients with preoperative SjvO2>75% (85.1±4.9% and 85.3±5.6% vs. 84.4±4.0%, p>0.05). Conclusion: SjvO2 increased significantly after craniotomy and durotomy in severe head ịnjured patients with low or normal preoperative SjvO2 values.
