[Anesthesia management for laparoscopic prostatectomy and open prostatectomy]

For anesthetic management of traditional open prostatectomy, preparation for hemorrhage is necessary. However, it has been considered that the amount of bleeding under laparoscopic prostatectomy is less than that of traditional open surgery.

The amount of bleeding and autologous blood preparation, fluid balance, and anesthetic management were investigated in patients who had undergone laparoscopic or open prostatectomy at the Nippon Medical School Hospital between June, 2004 and November, 2005, retrospectively. The difference of these aspects between the two surgical method groups was evaluated.

Thirty-two patients underwent prostatectomy in the investigation period. In these patients, 4 patients were excluded due to incomplete anesthesia record or change of surgical method. The amount of bleeding, and both amount of autologous blood preparation and transfusion in the laparoscopic surgery were less than those in the open surgery. There were no significant differences in the fluid balance and amount of urine output between the two groups.

We conclude that preparation of autologous blood transfusion is necessary for the traditional open prostatectomy, but not for the laparoscopic prostatectomy.
