RESUMO
The patient was a 22-year-old woman with no comorbidities who was transferred to our hospital due to cardiac arrest. Treatment enabled return to spontaneous circulation in the patient before arriving at the hospital. At the hospital, the patient's vital signs were unstable. Vasopressors and hyperhydration therapy were administered. Computed Tomography (CT) showed no remarkable change that caused the cardiac arrest. Antibiotics were prescribed after a blood culture exam. The patient was admitted to the ICU. In the ICU, the high-capacity vasopressors, hyperhydration therapy and transfusion of fresh frozen plasma were continued. Two hours after examining the blood culture, the results remained positive. Gram staining revealed Streptococcus, and the antibiotics were switched to penicillin G potassium, clindamycin and immunoglobulin was added. Hyperhydration therapy caused respiratory failure. Ten hours after admission to the ICU, extracorporeal membrane oxygenation was introduced, but the patient's general status did not improve. The patient died at 40 hours after admission. Blood culture results proved Streptococcus pyogenes; T and M serotypes were unclassifiable. The emm genotype was emm22. Regarding fever toxin genes, speA and speB were positive, and speC was negative. Among CsrS, CsrR and Rgg amino acid sequences, mutations in CsrS were detected.
RESUMO
PURPOSE: In Japan, the vehicle used in pre-hospital trauma care systems with physician-staffed ground emergency medical services (GEMS) is referred to as a "doctor car". Doctor cars are highly mobile physician-staffed GEMS that can provide complex pre-hospital trauma management using various treatment strategies. The number of doctor car operations for patients with severe trauma has increased. Considering facility factors, the association between doctor cars and patient outcomes remains unclear. Therefore, this study aimed to examine the relationship between doctor cars for patients with severe trauma and survival outcomes in Japan. METHODS: A nationwide retrospective cohort study was conducted to compare the impact of the doctor car group with the non-physician-staffed GEMS group on in-hospital survival in adult patients with severe trauma. The data were analyzed using multivariable logistic regression models with generalized estimating equations. RESULTS: This study included 372,365 patients registered in the Japan Trauma Data Bank between April 2009 and March 2019. Of the 49,144 eligible patients, 2361 and 46,783 were classified into the doctor car and non-physician staffed GEMS groups, respectively. The adjusted odds ratio (OR) for survival was significantly higher in the doctor car group than in the non-physician staffed GEMS group (adjusted OR = 1.228 [95% confidence interval 1.065-1.415]). CONCLUSION: Using nationwide data, this novel study suggests that doctor cars improve the in-hospital survival rate of patients with severe trauma in Japan. Therefore, doctor cars could be an option for trauma strategies.
RESUMO
We compared the recovery time from neuromuscular blockade induced by rocuronium combined with sugammadex versus succinylcholine during electroconvulsive therapy (ECT). Anesthesia was induced using propofol, followed by succinylcholine (1 mg/kg) or rocuronium (0.6 mg/kg). Immediately after the seizure stopped, 16 mg/kg sugammadex was infused. Neuromuscular monitoring was performed and continued until recovery of the train-of-four ratio to 0.9. We compared the recovery time of T1 to 10 and 90% between groups. Patients were also assessed for clinical signs, such as time to first spontaneous breath from the administration of muscle relaxant and eye opening to verbal commands. Although recovery time of T1 to 10 and 90% in the rocuronium-sugammadex group was shorter than in the succinylcholine group, the difference was not statistically significant. Further, the seizure duration with succinylcholine (33 ± 8 s) was shorter than that with rocuronium-sugammadex (39 ± 4 s). In conclusion, this study demonstrates the potential benefit of use of rocuronium-sugammadex as an alternative to succinylcholine for muscle relaxation during ECT.

Adrenaline is one of the most commonly used drugs in anesthesia, intensive care and pain medicine. This organic substance was first isolated by a Japanese scientist, Jokichi Takamine, with an ingenious technical assistance by Keizo Uenaka. Although 111 years have passed from their success, the brightness of this achievement has never faded. Also, conflicts provoked after the invention suggest many fundamental issues regarding scientific invention and business. Anesthesiologists, who take big benefits of adrenaline, should correctly understand how this useful drug became available widely in the world and why the name was fluctuated between "adrenaline" and "epinephrine".

INTRODUCTION: Staphylococcus aureus produces numerous toxins, such as toxic shock syndrome toxin 1 (TSST-1) and Panton-Valentine leukocidin (PVL). We isolated community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) strains producing both TSST-1 and PVL isolated from severe necrotizing pneumonia cases in a Nepali family. Detection of these CA-MRSA strains is rare in the world, and infection with these strains can take a rapidly progressive and lethal course. In this study, we traced the clinical course of this case and conducted a genetic analysis of the isolated strains. CASE REPORT: We described 2 familial cases (a 20-year-old male and 61-year-old female) of severe necrotizing pneumonia caused by CA-MRSA with the TSST-1 and PVL genes. A 20-year-old Nepalese male was admitted to our hospital after a 3-day history of high fever and coughing. Despite resuscitation efforts, he died of multiple organ failure. A 61-year-old Nepalese female was admitted to our hospital with a complaint of high fever and dyspnea for 1 day. She was the grandmother of the male subject and mostly stayed at his residence in Japan. We administered intravenous antibiotics, including anti-MRSA antibiotics, and she improved in 2 weeks. The sequence type of the isolates was ST22/SCCmec type IVa, and the spa type was t005. The virulence genes detected were as follows: PVL gene (lukSF-pv), TSST-1 gene (tst-1), sec, seg, sei, sel, sem, sen, seo, and seu. ST22 was not the dominant CA-MRSA clone type in Japan. Some of the reports demonstrated that PVL-/TSST-1-positive ST22-MRSA strains are prevalent in Nepal. Therefore, the MRSA strains were thought to be acquired from Nepal. CONCLUSION: These cases highlight the emergence of TSST-1- and PVL-positive CA-MRSA infection and its association with life-threatening community-acquired necrotizing pneumonia. Clinicians should note the possibility of introducing MRSA strains from abroad and be aware of this illness to initiate appropriate treatment.
RESUMO
Estimating nutrient consumption and administering appropriate nutritional therapy is essential for improving clinical outcomes in critically ill patients. Various equations, such as the Harris-Benedict equation, have been developed to estimate the required calories. Previous equations, however, targeted Westerners, whose physical characteristics are likely different from those of Asians. Hence, it is unclear whether these equations can be used for Asian patients. This study focused specifically on sepsis patients admitted to a single Japanese ICU, and aimed to develop novel equations to estimate their total energy expenditure. A total of 95 sepsis patients were included in this study. We measured resting energy expenditure (REE) by using indirect calorimetry, and created equations to calculate basal metabolic rate (BMR) using height, weight and age as variables. REE was predicted by multiplying BMR by the novel equation with the stress factor of 1.4. The prediction error of our novel equations were smaller than those of other conventional equations. We further confirmed the accuracy of our equations and that they were unaffected by patient age and disease severity by using data obtained from another patient group. The current study suggested that these equations might allow accurate estimation of the total energy expenditure and proper management of nutritional therapy in Asian sepsis patients.
