Abstract
The coronavirus disease 2019 (COVID-19) pandemic continues to spread around the world. In April 2021, Japan experienced a fourth wave of COVID-19 infections, which led to the breakdown of the medical system. Osaka, Japan, was particularly affected, with many severe cases and the highest number of COVID-19-associated deaths in Japan. Herein, we present a patient with severe COVID-19 infection who received prolonged midazolam (MDZ) treatment since propofol was not available due to shortage of medical resources. Moreover, the duration of mechanical ventilation was extended due to the development of a pneumothorax. When MDZ tapering was initiated, tachypnea was observed, which resulted failure in ventilator weaning. However, the use of continuous morphine infusion led a successful weaning off the ventilator. We suggest that the administration of morphine may allow for a smoother weaning process for some patients with severe COVID-19 infection.

Abstract
PURPOSE The ProSeal™ laryngeal mask airway (PLMA) can be more difficult to insert than the classic laryngeal mask, especially in patients who have a thin palate with a steep oropharyngeal curve. Here, an oral gastric (OG) tube-guided technique is considered as a method that makes it easier to successfully insert a PLMA. METHODS Sixty patients who were scheduled to undergo general anesthesia without neuromuscular blocking were randomly allocated into two groups: 30 patients with PLMA inserted by the standard digital technique, and 30 with the PLMA inserted by an OG tube-guided technique. Most PLMA insertions were performed by less experienced users. The success rate at the first attempt, the time taken to insert the PLMA, the difficulty of the procedure, and the incidence of oropharyngeal trauma and postoperative sore throat were compared between the two groups. RESULTS PLMA insertion was successfully achieved at the first attempt using the OG tube-guided technique in all 30 patients. The OG tube-guided insertion required fewer attempts (P = 0.04) and led to a less difficult insertion procedure (P = 0.02) than the standard digital insertion. Effective ventilation during anesthesia was achieved in all patients, with a lower mean cuff pressure in the OG tube-guided technique group (P = 0.02). The frequency of blood sticking to the PLMA tube (P < 0.001) and the incidence of postoperative sore throat (P = 0.003) were lower in the OG tube-guided group than the standard digital technique group. CONCLUSIONS OG tube-guided PLMA insertion is easier for less experienced users, trainees, and experts as well as less invasive for patients than the standard digital insertion.

Abstract
BACKGROUND Stressful procedures such as intratracheal intubation and direct laryngoscopy in very short operations make anesthetic management for laryngomicrosurgery difficult. This study was conducted to evaluate which anesthetic agent, remifentanil or fentanyl, is suitable in anesthesia for laryngomicrosurgery. METHODS After obtaining informed consent prior to the study, 18 patients undergoing elective laryngomicrosurgery were randomly allocated to one of two groups to receive remifentanil (R group) or fentanyl (F group). Patients with ages above 76 years and moderate abnormalities in cardiovascular system or respiratory system were excluded. RESULTS Average infusion rate of remifentanil was 0.24 +/- 0.02 microg x kg(-1) x min(-1) and total infused dose of fentanyl was 0.27 +/- 0.05 mg. Average bispectral index values in both groups were comparable. Cases needing sevoflurane inhalation to control blood pressure were significantly more in F group than in R group. Heart rate was significantly lower in R group than in F group. Duration from the end of operation to responses to verbal commands and extubation was significantly shorter in R group than in F group. CONCLUSIONS Remifentanil provided faster recovery and hemodynamic stability. Therefore, remifentanil seems to be more suitable than fentanyl in anesthesia for laryngomicrosurgery.

Abstract
BACKGROUND We are accustomed to right internal jugular vein (IJV) cannulation guided by pulsation for 20 years or more. This study was conducted to evaluate whether this method is a safe and certain method. METHODS After obtaining informed consent, 100 elective surgical patients requiring central venous catheterization during perioperative period were randomly assigned to either the pulsation group in which IJV pulsation was used for a landmark of puncture or the US group in which IJV was recognized with ultrasonography before puncture. RESULTS Pulsation was observed in 98 patients. Successful rate of first attempt with a 23 G seeking needle was 85.7% in the pulsation group and 86% in the US group. IJV was successfully cannulated at 1 pass in the entire pulsation group and 92% in the US group. The frequency of puncture with cannula was significantly lower in the pulsation group than that of the US group. Arterial puncture with the seeking needle was recorded in 3 patients in the US group. Successful rate of first attempt in this study was comparable to other studies using ultrasonographic guidance. CONCLUSIONS Internal jugular vein cannulation by pulsation method is a safe and certain method.

Abstract
BACKGROUND Our previous reports showed that elastic stockings (ES) combined with intermittent pneumatic compression (IPC) significantly decrease the incidence of perioperative pulmonary thromboembolism (PTE). This study was conducted to investigate whether ES with IPC is useful to prevent PTE in cancer patients. METHODS No prophylactic strategies were employed from January 1998 to December 1999 (4511 cases). ES combined with ICP apparatuses was employed from May 2000 to April 2008 (20,383 cases). Details of the methods were described in our previous reports. RESULTS Age, anesthesia duration and operation duration increased statistically without clinical significances after the induction of prophylactic strategies. About 90 per cent of surgical patients had malignant disease. Seven patients developed PTE without any interventions and 5 patients with treatments. The incidence of PTE decreased significantly from 15.51 persons/10,000 cases to 2.45 persons/10,000 cases. Cardiac arrest occurred in two untreated patients but in no treated patient. Intervention also significantly decreased the incidence of cardiac arrest. CONCLUSIONS The combination of ES and ICP seems to be useful to decrease the incidence and severity of perioperative PTE in cancer patients in Japan.

Abstract
We report an experience of anesthetic management of the ex-utero intrapartum treatment (EXIT) procedure performed in a fetus with congenital high airway obstruction syndrome (CHAOS) due to laryngeal atresia at 30 weeks' gestation. Anesthesia of the mother was induced with rapid sequence, and maintained with 3.5% sevoflurane in 100% oxygen and fentanyl before delivery. Two minimum alveolar concentration (MAC) sevoflurane provided excellent uterine relaxation without maternal hypotension. After hysterotomy, a sterile pulse oxymeter was placed on the fetus hand for monitoring fetal SpO2 and pulse rate, and a Doppler ultrasound transducer was applied to monitor fetal heart rate. Fentanyl (5 microg x dl(-1)) and pancuronium (0.2 mg x dl(-1)) were injected into the fetal upper arm in addition to transplacental anesthetic agents. The fetal heart rate and SpO2 were stable throughout the fetal manipulations, but the rise in SpO2 after initiating ventilation via tracheostomy was very slow. The uterine tone improved soon after discontinuing sevoflurane and oxytocin infusion was started after delivery. Surfactant administration before first ventilation is recommended in preterm babies undergoing EXIT procedure, and capnometer may be useful to confirm the adequate ventilation before cutting the umbilical cord.

Abstract
Brugada syndrome is an arrhythmia syndrome characterized by typical electrocardiogram (Brugada-type ECG) and development of ventricular fibrillation (Vf) without any distinct structural heart diseases. The essential goal in the management of Brugada syndrome is to avoid the development of Vf. However, there has been no established consensus on pre-operative risk assessment of patients with Brugada-type ECG. We recently experienced two cases of anesthetic managements for patients with Brugada-type ECG. Based on these experiences and recent cardiological progress on the risk stratification of Brugada syndrome, we thoroughly discuss on the peri-operative managements for patients with Brugada-type ECG.
