Importance of scientific ocean drilling was becoming more widely known in the Japanese scientific community, based upon the results of DSDP/IPOD/ODP by late 80s. Many scientific and engineering discussions took place domestically and internationally, and finally those discussions led the Japanese government to decisively move forward with the construction of D/V Chikyu. Finally, Chikyu was delivered to the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) in July 2005. Chikyu was designed and built as a scientific ocean drilling vessel capable of riser drilling in water depths of 2,500 m (future target is 4,000 m class). Chikyu can drill in deeper water and to deeper sub sea floor depths than any other scientific drilling platforms. Chikyu’s large hull makes it possible for a large onboard laboratory, with space for large analytical instruments and facilities. Since the first scientific operation conducted in the Nankai Trough in 2007, Chikyu made significant scientific achievements by IODP Expeditions. Those results are briefly introduced and show a future operation challenge with introducing Chikyu’s general features.

The present study used data from anesthetic records to analyze variables of intracranial pressure (ICP) during brain tumor surgery or in the early postoperative period as prognostic indicators in dogs. Data from 17 dogs which were scheduled to undergo elective craniotomy for brain tumor surgery from 2009 to 2012 were included. Of these, five (29.4%) died during 14 days after the surgery because of respiratory failure following pneumonia (n=2), euthanasia due to difficulty in treatment of status epilepticus (n=1), tumor-bed hematoma (n=1), and unknown reason (n=1). In the 12 surviving dogs, neurological signs were improved or resolved at discharge. All dogs were administered midazolam and droperidol-fentanyl as premedication. General anesthesia was induced using propofol maintained on isoflurane and oxygen. Direct ICP was obtained via a Codman Microsensor strain gauge transducer. ICP hypertension (>13 mmHg) measured after 15 min of recovery from the moment after discontinuation of anesthesia by turning off the vaporizer dial was associated with poor prognosis (odds ratio, 20.00; 95% confidence interval, 1.39−287.60, P=0.028). This suggests that intracranial pressure influences the postoperative mortality rate in dogs undergoing brain tumor surgery.
