Pediatric Anesthesiology Department

Introduction of the department

This department is charge of anesthetic and perioperative management in the Pediatric Medical Center established as a “last defense” in pediatric medicine at Okayama University Hospital. It has worked with many anesthetic cases, including high-risk cardiac anesthesia, as conducted at children hospitals. It has had an increasing number of opportunities to provide state-of-the-art medical care, including many cases of analgesia or sedation and high-risk pediatric anesthesia. The Department of Pediatric Anesthesiology tries to meet the needs as a part of the “last defense” and provides safe and patient-friendly anesthetic care.

Treatment system

The anesthesiologist, sufficiently trained at pediatric specialized hospitals in Japan and overseas, is in charge of sedation, analgesia, anesthesia, and perioperative management, in cooperation with physicians and nurses in the departments of pediatric surgery and medicine and other surgical specialties.

Treatment policy

Using state-of-the-art knowledge and technology to perform anesthesia and perioperative management, this department makes a safe, secure, and patient-friendly offer of prolonged sedation or sufficient analgesia necessary for anesthesia, examination, and treatment necessary for surgeries conducted in the Pediatric Medical Center.


Because this department characteristically responds to requests from other departments, it might be more appropriate to say that it has no field out of its line than that it has some specialties. Keeping safe, reliable and patient-friendly service in mind, it performs perioperative managements to respond to all the cases: MRI and CT examinations; surgeries for abdominal fissure and congenital diaphragmatic hernia; open-heart operation for complex cardiac anomaly including single ventricle and transportation of the great arteries. Additionally, it has many experiences of intensive cares for severe patients including postoperative follow-up management, showing good performance in cooperation with other specialties.

Scope of Target diseases

The department provides anesthetic treatments on a round-the-clock basis, responding to various surgeries and examinations such as general pediatric surgeries, pediatric emergency operations, open-heart operations for congenital cardiac diseases, neonatal surgeries, and cardiac catheter tests. It also provides anesthesia or sedation for MRI and CT examinations.

Description of medical care

Analgesia and sedation

In examinations requiring subtle procedures such as a cardiac catheter tests and MRI and CT examinations, patients must be placed at rest for a certain period to prevent their unexpected body motion. So, it is also necessary for a child patient that analgesia and sedation be performed using drugs. Long rest and sufficient pain alleviation are necessary for examinations and treatments to be provided on a safe, certain, and patient-friendly basis. For patient with severe diseases, respiratory and cardiovascular management are actively performed so that the patients can safely undergo examinations and procedures.

Anesthesia and perioperative management

Pediatric anesthesia has a higher risk of perioperative complication than adult anesthesia. Furthermore, specificities of children themselves and pediatric diseases demand different knowledge and techniques from adult anesthesia, as they do for all physicians of other departments that target children’s diseases. Pediatric anesthesiologists with sufficient knowledge and experience of pediatric anesthesia perform preoperative whole-body management as needed prior to the surgery, give appropriate anesthesa to child patients, who will undergo surgeries in various surgical specialties depending on their disease conditions, and perform postoperative acute whole-body management in severe cases.

Intensive care management

While providing perioperative management for child patients from the departments of pediatric cardiac surgery, pediatric surgery, and pediatric cerebral surgery, a pediatric anesthesiologist experienced in intensive care performs intensive care on a round-the-clock basis for severe patients referred by the various departments of the Okayama University Hospital and other hospitals in cooperation with each department. We perform the whole-body management including specialized treatments such as nitric oxide inhalation therapy nitrogen inhalation therapy, hypothermia, extracorporeal membrane oxygenation (ECMO); continuous blood purification therapy, and peritoneal dialysis for child patients with severe respiratory failure caused by cardiac failure and pneumonia, septic shock, for acute encephalitis and encephalopathy, and hematological malignancy. children after cardiopulmonary arrest.
