[ XXXX after turning to the prone position].

@entity1 @entity6358 @entity75 @entity1875 @entity5433 @entity551 @entity3575
@entity551 after positioning is sometimes seen especially in @entity1 with cervical spinal lesion operated on under prone position. @entity1 with spinal lesion and those with @entity75 are compared in the frequency of @entity551 after positioning to prone. Sixty-one cases operated on with prone position were studied. Ages ranged from 40 to 82 (mean 61) years and ASA grade was 1 or 2 in each case. Cervical laminoplasty (group C) or craniotomy (group B) are performed in 40 and 21 @entity1 , respectively. @entity6358 was administrated when the systolic blood pressure decreased under 80 mmHg and the frequency of @entity6358 use was compared. There were no differences in age and sex distribution between group C and B. The induction doses of @entity1875 and @entity3575 in group B were larger than those of group C, but ephedrine use in group C was more frequent than in group B. In T2-weighted image of the cervical cord, high signal intensity areas were depicted in cases with @entity551 . The sympathetic flow descends in the medial part in the lateral funiculus. Damage of this pathway would cause @entity5433 in @entity1 with cervical spinal lesion and strict monitoring is necessary during positioning to prone.
