ABSTRACT
To evaluate the application of blood salvage techmque in spine orthopaedic operation. 26 cases of spine orthopaedic operations were divided into two groups. Group A received homologous blood transfusion. Group B received intraoperative blood salvage by cell saver in spine orthopaedic operations. No complications of transfusion and dysfunciton were found in all pateints. The results showed that blood salvage technique can decrease effectively the need of homologous blood transfusion in spine orthopaedic operation and can be used safely in clinical practice.

Objective To provide anatomical basis for endoscopic endonasal transsphenoidal surgery for excision of sellar tumors. Methods The relationship between ostia of sphenoidal sinus and sellar areas of 25 heads of adult cadavers, and the structure of pituitary fossa and the relationship of the anterior-posterior clinoid processes of 21 heads of adult cadavers were observed and measured. At the same time, structure of 9 fresh heads of adult cadavers were observed with the operating endoscope. Results The distance between the ostia of the sphenoidal sinus to the tuberculum sellae, internal carotid artery, optic nerve and dorsum sellae were 14.6?3.0mm, 13.7?2.2mm, 11.6?1.8mm, and 22.6?3.2mm, respectively. The sagittal diameter of the pituitary fossa was 10.2?1.5mm. The transverse diameter of the pituitary fossa was 1.4?2.4mm. The distance between two anterior clinoid processes was 25.0?3.0mm. The distance between two posterior clinoid processes was 15.8?3.3mm. The distance between anterior clinoid process and ipsilateral posterior clinoid process was 7.8?1.7mm. The distance between anterior clinoid process to contralateral posterior clinoid process was 21.8?2.4mm. Conclusion These results would provide the surgeons a stereoscopic image about sellar areas, so that the operative field could be accurately defined in endoscopic endonasal transsphenoidal surgery for the excision of sellar tumors.
