Anesthesiology and Intensive Care Unit

Introduction
Perioperative care for cancer patients with limited vital organ function is a major challenge for nesthesiologists as, in general, anesthesia and surgery may further deteriorate physiological functions. Perioperative impairment of vital organ function has traditionally been defined as surgical stress determined quantitatively by measuring the physiological parameters representing the corresponding organs. Recent evidence suggests that such a stress response to surgery involves not only vital organs but also the neuroendocrine- immune system and persists for several days after surgery. Thus, the aim of our anesthetic management is to protect patients from surgical stress by blocking the noxious influences of surgical trauma. This is achieved by regarding the anesthetic management as perioperative care.

Routine Activities　
As stated above, our colleagues (four staff anesthesiologists and one to two residents) are working as anesthetists and intensive care physicians.
In 2001, we performed 1972 anesthetic proce-dures. The annual number of patients admitted to the intensive care unit (ICU) amounted to 1127. Our concern in ICU management is not only postoperative cardiorespiratory care but also the critical care of patients who have developed organ failure after medical or surgical cancer treatment. The cumulative number of patients with organ failure treated in the ICU since the establishment of the National Cancer Center Hospital East is 265.
An outpatient clinic system was introduced in 1997 to improve preoperative evaluation of anesthetic risk in surgical patients and to participate in the management of intractable pain. In 2001, we performed analgesic nerve blocks in 4 cases. This system will further improve patient safety and the quality of pain control.
Daily activity starts with ICU rounds and pre-anesthesia case presentation. ICU rounds are also made every evening after the completion of elective surgical procedures. A journal club is held twice a week to maintain up-to-date knowledge of recent advances in anesthesia and critical care medicine.

New Developments
Ongoing clinical studies are as follows;
1) Establishment of perioperative management for abdominal surgery patients with severely limited pulmonary function.
2) Development of new intraoperative respiratory management for adequate ventilation and oxyge-nation.
3) Establishment of airway and respiratory manage-ment for patients with upper airway obstruction.
Future research activities will be directed toward the establishment of new methods of perioperative care in thefield of surgical oncology.
