Abstract:
Objective To investigate the immune cell population change during the anesthesia process in patients undergoing craniotomy surgery. Methods A total of 18 patients undergoing craniotomy who had an inhalational general anesthetic were selected as our subjects. Blood samples were collected before anesthesia (T0)and 30 min(T1),45 min(T2),60 min(craniotomy operated,T3),120 min(tumor resected,T4)and 240 min(T5)after anesthesia. Blood cell counts including neutrophils,monocytes and lymphocytes were determined along with lymphocyte subpopulations( T cells,inducer and helper T cells,suppressor and cytotoxic T cells,NK cells,B cells ). Data were analyzed by SPSS 13. 0 software. Results In terms of the immune cell during neuroanesthesia,induction neutrophils,monocytes and lymphocytes decreased significantly from( 4. 50 ± 2. 00 ) × 109/L(,0. 51 ± 0. 22)× 109/L,(1. 90 ± 0. 70)× 109/L to(3. 10 ± 1. 50)× 109/L,(0. 32 ± 0. 17)× 109/L, (1. 10 ± 0. 50)× 109/L at the 30 min after anesthesia,and the differences were significant( P﹤0. 05). It also showed that Ts and NK cells decreased significantly from( 0. 55 ± 0. 29 )× 109/L,( 0. 32 ± 0. 14 )× 109/L to (0. 33 ± 0. 22 )× 109/L,( 0. 10 ± 0. 08 )× 109/L at the 30 min after anesthesia,and the differences were significant( P﹤0. 05 ). Conclusion Special and non special immune system are inhibited during craniotomy, especially at the early anesthesia. Among the inhibited immune cells,neutrophils recover early and followed Ts and NK cells.
