Focused Review: Efficacy of the Rector Spinae Plane Block  [PDF]
Hironobu Ueshima, Hiroshi Otake
Open Journal of Anesthesiology (OJAnes) , 2018, DOI: 10.4236/ojanes.2018.87022
Abstract: Since the original publication on the erector spinae plane (ESP) block in 2016, the technique of the ESP block has evolved significantly in the last few years. This review highlights recent developments in the technique for administering the ESP block and proposes directions for future research. Continuous efforts are being aimed at improving understanding regarding the administration of the ESP block. Current reports suggest that the ESP block provides effective analgesia in thoracic and abdominal sites in patients of all ages. However, no cohort studies or randomized controlled trials were performed in 2016 and 2017. The ESP block is an effective analgesic tool in a wide range of sites. However. We are uncertain how effective the ESP block is compared to other types of regional anesthesia. Therefore, more research on ESP blocks is required.

Methods: We examined the baseline data from 4356 healthy workers (3556 men and 800 women) aged 19–69 years. The physical activity of each participant was classified according to the International Physical Activity Questionnaire (IPAQ). We defined four components of MetS diagnostic components in this study as follows: 1) high blood pressure (BP) systolic BP [SBP] ≥ 130 mmHg, or diastolic BP [DBP] ≥ 85 mmHg, or on medication; 2) dyslipidemia (high-density lipoprotein-cholesterol concentration ,40 mg/dL, or triglycerides concentration ≥150 mg/dL, or on medication; 3) impaired glucose tolerance (fasting blood sugar concentration ≥ 110 mg/dL, or if less than 8 hours after meals ≥ 140 mg/dL), or on medication; and 4) overweight (body mass index [BMI] ≥ 25 kg/m2), or obesity (BMI ≥ 30 kg/m2). There were 680 participants in the group, with sleep duration <6 hours (15.6%). Results: Those who had 0–4 MetS diagnostic components, including overweight, accounted for 2159, 1222, 674, 255, and 46 participants, respectively, in the Poisson distribution. Poisson regression analysis revealed that independent factors that contributed to the number of MetS diagnostic components were being male (regression coefficient b = 0.752, P < 0.001), age (b = 0.026, P < 0.001), IPAQ classification (b = -0.238, P = 0.034), and alcohol intake (mL/day) (b = 0.018, P < 0.001). Short sleep duration (<6 hours) was also related to the number of MetS (b = 0.162, P < 0.001). The results of analyses with obesity component showed a similar association. Conclusion: Short sleep duration was positively associated with the number of MetS diagnostic components independent of other lifestyle habits. Keyword:
Regardless of the Puncture Angle, a Tuohy Needle with Sand-Blasted Steel at the Tip of the Bevel Is a Valid Needle on the Ultrasonic Images  [PDF]
Yuki Ichikawa, Hironobu Ueshima, Hiroshi Otake, Akira Kitamura
Open Journal of Anesthesiology (OJAnes) , 2016, DOI: 10.4236/ojanes.2016.67017
Abstract: Background: A high ability to visualize the needle on the ultrasonic images is necessary to perform the ultrasound-guided nerve block safely. The Rafa Tuohy needleR (Vygon, Paris, France, Rafa) is a non-stimulating Tuohy needle with sand-blasted steel at the tip of the bevel. We examined the degree to which the Rafa enhanced the visibility of ultrasonic images compared with the non-coated Tuohy needle. Methods: We punctured the Blue Phantom. The dimensions of both the Rafa and the non-coated Tuohy needles were 18 G × 80 mm. The puncture angle is 30 degrees and 45 degrees from the Blue Phantom. We measured the intensity of the tip of the bevel at a depth of 0.5, 1.0, 1.5 and 2.0 cm for the puncture angle of 30 degrees, and 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 cm for the puncture angle of 45 degrees. Six anesthesiologists with more than seven years of experience performed three punctures using each needle. Results: As an outcome, we concluded that at a puncture angle of both 30 degrees and 45 degrees, the intensity of the non-coated Tuohy needle decreased with the depth. On the other hand, at an angle of 30 degrees, the intensity of the Rafa needle did not decrease, and at an angle of 45 degrees the intensity only decreased very slightly as the depth increased. Conclusions: The Tuohy needle with sand-blasted steel at the tip of the bevel provided greater visualization than the non-coated Tuohy needle on the ultrasound images.
PECS Block Provides Effective Postoperative Pain Management for Breast Cancer Surgery—A Retrospective Study  [PDF]
Ichikawa Yuki, Hironobu Ueshima, Hiroshi Otake, Akira Kitamura
International Journal of Clinical Medicine (IJCM) , 2017, DOI: 10.4236/ijcm.2017.83019
Abstract: We investigated the efficacy of ultrasound-guided pectoral nerves (PECS) block for modified radical mastectomy surgery retrospectively. Methods: We measured that pain scores and the use of additional analgesic drugs were recorded in the postoperative care unit within 24 hours after the operation. Postoperative complications (i.e., nausea and vomiting) were noted. Results: Patients who received the PECS block under general anesthesia (PECS group) reported lower visual analog scale pain scores at 0, 1, 2, 4, 6, 12, 24 hours after the operation than patients who did not receive PECS block under general anesthesia (control group). Moreover, the use of additional analgesic drugs during the first 24 hours after surgery was lower in the PECS group than in the control group. While in the postoperative care unit, the PECS group had less nausea and vomiting than the control group. Conclusion: The PECS block provides effective postoperative analgesia within the first 24 hours after breast cancer surgery.

Open Journal of Anesthesiology (OJAnes) , 2017, DOI: 10.4236/ojanes.2017.710035
Abstract: Background: Pectoral nerves (PECS) block has been reported to be effective for a perioperative analgesia for breast cancer surgery. In addition, we may consider that the PECS block is also effective for motor function in postoperative period. Therefore, we investigated the effect of PECS block for motor function in postoperative period. Methods: This study selected the patients performed the breast cancer surgery between April and September, 2015. The study surveyed the difficulty of movement of the upper limbs at postoperative day 5 (D5) and postoperative month 6 (M6) by performing telephone survey. We counted the number of patients who complained of the difficulty of movement of the upper limbs. All results were compared using the chi- squared test. P < 0.05 was considered statistically significant. Results: 93 patients received only general anesthesia (G group). 85 patients received PECS block with general anesthesia (P group). The number of the P group at D5 was 2 patients. On the other hand, the number of the G group was 15 patients (P = 0.042). In the same way, the number of the P group M6 was no patient. On the other hand, the number of the G group was 10 patients (P = 0.043). Conclusion: A PECS block is effective for motor function recovery in the early postoperative period after breast cancer surgery.

Open Journal of Anesthesiology (OJAnes) , 2019, DOI: 10.4236/ojanes.2019.93004
Abstract: Background: Poor perioperative pain management during pneumothorax surgery leads to respiratory complications in the post-operative period. The erector spinae plane (ESP) block technique has been shown to be able to block the thoracic spinal nerves. Therefore, the ESP block may provide effective analgesic during thoracic surgery. We have retrospectively investigated the effectiveness of the ESP block for postoperative pain management in pneumothorax surgery. Patients and Methods: Patients who underwent pneumothorax surgery in 2017 were selected for the study. The primary outcome was assessed using the numeric pain rating (NRS) scales until the morning of the second post-operative day. The secondary outcomes were the cumulative amount of additional intravenous fentanyl administration until the morning of the second post-operative day. Results: This retrospective study included 29 patients who underwent pneumothorax surgery. Of these patients, 13 patients received only general anaesthesia (control group), while the other 16 patients received the ESP block in addition to general anaesthesia (study group). Compared to the control group, the study group did not show lower NRS scores at 1, 2, 4, 6, 12, and 24 hours post-surgery (P = 0.09, 0.17, 0.06, 0.36, 0.47, and 0.71). As for the cumulative amount of additional fentanyl, there were also no significant differences between the both groups. Conclusions: The ESP block could not provide effective analgesia for the 24 hours post-surgery period in patients undergoing pneumothorax surgery.

Open Journal of Anesthesiology (OJAnes) , 2019, DOI: 10.4236/ojanes.2019.94006
Abstract: Background: An ear-fitting thermometer probe “NIPRO CE THERMO?” (Nipro Corporation, Osaka, Japan, new CE thermo) for both ears was newly developed in 2017. Since new release, we have never investigated about an accuracy of the new CE thermo. In this time, the accuracy of the CE thermo was investigated. Methods: The correlation between the tympanic membrane temperature, measured using the new CE thermo, and the esophageal temperature of 30 patients (right ear: 16 patients, left ear: 14 patients) was measured in the prospective observational study. Results: A good correlation (r = 0.721) and no measurement error (within 1?C in mean ± 2SD) between the two temperatures were observed using Bland-Altman analysis. The correlation and measurement error for each ear yielded the same results. Conclusion: The tympanic membrane temperature, measured using the new CE thermo, showed good correlation with the esophageal temperature and could be used as a central temperature in the perioperative period.

Health (Health) , 2012, DOI: 10.4236/health.2012.411161
Abstract: Background: Cardiovascular diseases (CVD) are major causes of death in Japan, and controlling the risk factors for CVD is an important public health task. Lifestyle factors, for example, diet and stress, have impacts on risk factors such as hypertension and hyperlipidemia. Deterioration of mental health is related to CVD pathogenesis. Aim: We investigated the relationships between levels of mental health, 4-year changes in lifestyle, and CVD risk factors among Japanese workers, using the SF-36 (Japanese version), which is a comprehensive scale measuring health-related quality of life. We hypothesized that workers’ mental health levels would influence 4-year changes in their lifestyles and CVD risk factors. Methods: Data from the High-Risk and Population Strategy for Occupational Health Promotion (HIPOP-OHP) study, which were collected by examination and administration of the SF-36, were used. The relationships between mental health levels at baseline, lifestyle chan- ges, and cardiovascular risk factors were longitudinally analyzed. Subjects with total SF-36 scores ≥65 were classified as the “Good Mental Health Group,” and those with total scores <65 were classified as the “Poor Mental Health Group.” Results: Multiple logistic regression analyses showed that, as compared to people who had poor mental health, those who had good mental health at baseline had a significantly higher probability of good maintenance of improvements in body mass index, (OR = 1.20, 95% CI: 1.03 - 1.39), blood pressure (OR = 1.20, 95% CI: 1.01 - 1.43), total cholesterol (OR = 1.07, 95% CI: 0.86 - 1.33) and HDL cholesterol (OR = 1.26, 95% CI: 1.07 - 1.47). Conclusion: Japanese workers with good mental health tend to improve or maintain good lifestyle conditions and minimize CVD risk factors, while those with poor mental health generally have difficulty improving their lifestyles and lowering their CVD risk.

Trials , 2011, DOI: 10.1186/1745-6215-12-96
Abstract: We examined clinical trials examining cardiovascular diseases that evaluated true endpoints and involved 300 or more participants using Pub-Med, Ichushi (by the Japan Medical Abstracts Society, a non-profit organization), websites of related medical societies, the University Hospital Medical Information Network (UMIN) Clinical Trials Registry, and clinicaltrials.gov at three points in time: 30 November, 2004, 25 February, 2007 and 25 July, 2009.We found a total of 152 trials that met our criteria for 'large-scale clinical trials' examining cardiovascular diseases in Japan. Of these, 72.4% were randomized controlled trials (RCTs). Of 152 trials, 9.2% of the trials examined more than 10,000 participants, and 42.8% examined between 1,000 and 10,000 participants. The number of large-scale clinical trials markedly increased from 2001 to 2004, but suddenly decreased in 2007, then began to increase again. Ischemic heart disease (39.5%) was the most common target disease. Most of the larger-scale trials were funded by private organizations such as pharmaceutical companies. The designs and results of 13 trials were not disclosed.To improve the quality of clinical trials, all sponsors should register trials and disclose the funding sources before the enrolment of participants, and publish their results after the completion of each study.Large numbers of clinical and non-clinical investigations are required to obtain evidence to improve the treatment of patients. This evidence can benefit the medical practice of health care providers by informing treatment guidelines and providing the rationale on which to make treatment decisions.Clinical trials are necessary for producing appropriate clinical evidence. In clinical trials examining cardiovascular diseases, large-scale clinical trials with thousands of participants are often required to evaluate the risks of cardiac events and/or death, because it is necessary to evaluate the incidence of cardiovascular events that are relativ

Noriaki Sakamoto, Masato Yamaguchi, Takuya Okada, Koji Idoguchi, Eisuke Ueshima, Akhmadu Muradi, Koji Sugimoto
Journal of Biomedical Science and Engineering (JBiSE) , 2012, DOI: 10.4236/jbise.2012.512A095

A 77-year-old man who received transarterial chemoembolization for large hepatocellular carcinomas complained of acute pain in the upper abdomen and suddenly developed severe jaundice, anemia, and massive hematuria. Abdominal computed tomography demonstrated gas gangrene at the tumor site. Clostridium perfringens was identified from blood samples and drainage cultures from the liver abscess. Despite intensive treatment, the patient died 55 hours after chemoembolization due to multiple organ failure. When treating patients with large tumors, such as in our case, this rare but fatal complication that causes sepsis and hemolysis with lightning-like rapidity should be considered.
