There are abundant cases of obstetric emergencies demanding prompt intervention. Emergency cesarean sections are classified into stable, urgent and immediate surgeries, although there is significant overlap between three groups. Stable emergency cesarean sections are performed in patients with stable maternal and fetal physiology, but who need surgery before unstability occurs. ⋯ In the event of sustained fetal bradycardia caused by placental abruption, cord prolapse, uterine rupture etc, delivery by immediate cesarean section within 25 minutes improve long-term neonatal neurologic outcome. Although cardiopulmonary arrest in pregnancy is very uncommon, peripartum cesarean section should be considered within 5 minutes not only for maternal resuscitation but for neonatal survival. Only a well-coordinated teamwork of all involved specialities will guarantee optimal prognosis of mother and fetus.

The annual incidence of aneurysmal subarachnoid hemorrhage (SAH) is approximately 20 per 100,000/ year in Japan, and it is suggested that approximately 40% of SAH patients have poor outcome. Rebleeding after SAH and delayed cerebral vasospasm are the most important causes of poor outcomes. Particularly, rebleeding significantly worsened the outcome, therefore, its prevention is of utmost importance. ⋯ At present, surgical clipping remains the method of choice in Japan. However, there has been growing acceptance that the efficacy of endovascular treatment is comparable to that of surgical treatment, suggesting endovascular treatment should be considered in suitable patients with ruptured cerebral aneurysms. In this report, we describe the proceedures for the standard management of SAH, in particular, treatment of ruptured cerebral aneurysm and selection of treatment measures, according to the Japanese guidelines for the management of aneurysmal subarachnoid hemorrhage.

Comparative Study
[Comparison of continuous cardiac output measurement methods: non-invasive estimated CCO using pulse wave transit time and CCO using thermodilution].
esCCO (estimated continuous cardiac output, Nihon Kohden, esCCO) is a new cardiac output measurement system which uses pulse wave transit time to calculate cardiac output continuously and non-invasively. One of the most commonly used methods to monitor cardiac output is continuous cardiac output CCO (Edwards Lifesciences) which has an accuracy equivalent to that of thermodilution method. ⋯ This result suggests that esCCO could be used to measure cardiac output accurately and non-invasively in different cases.

Comparative Study
[Influence of intraoperative fentanyl and remifentanil infusion on early postoperative oral intake after general anesthesia].
There is no reports on influence of intraoperative fentanyl and remifentanil infusion on ability of oral intake after short stay surgery under general anesthesia. ⋯ With or without the use of remifentanil, greater the amount of fentanyl used, greater the percentage of patients unable to eat. Amount of fentanyl used in R group was significantly less than in group NR; however the difference in percentage of patients unable to eat supper was not observed.

Case Reports
[Case of successful management with mirtazapine for prolonged pain after esophagectomy].
This case report describes a successful outcome of mirtazapine treatment in a patient with difficult post-thoracotomy pain. A 63-year-old man received thoracotomy for the resection of esophageal tumor. The pain continued 2 years after the operation. ⋯ Since then, his weight slightly increased and the administration of mirtazapine was stopped in accordance with the patient's request. The pain became worse again. Therefore, mirtazapine, commonly used as an antidepressant agent, was considered to be beneficial for neuropathic pain as an analgesic adjuvant.
