ABSTRACT

BACKGROUND: We report the anesthetic management of inguinal hernia repair for an infant with subglottic stenosis. A previously scheduled operation had been cancelled due to unexpected airway trouble during the induction. CASE PRESENTATION: A boy was born at 24 weeks of gestation and his trachea was intubated for 45 days. At 16 months old, surgery for inguinal hernia was planned, but cancelled due to unexpected narrow airway, and subglottic stenosis was first suspected. At 17 months old, he was transferred to us for inguinal hernia surgery. After careful discussion between the surgical team and the anesthesiologists, a strategy to manage this patient was developed. He underwent open hernia surgery under spinal anesthesia and diagnostic rigid bronchoscopy under tubeless general anesthesia separately, which revealed low-grade stenosis and some subglottic cysts. The postoperative course was uneventful. CONCLUSION: Interdepartmental discussion weighing risks and benefits may deduce the safest and most appropriate anesthesia method.

ABSTRACT

BACKGROUND AND AIM: Exercise is beneficial for metabolic syndrome. Fatty liver and significant hepatic fibrosis, hepatic manifestations of metabolic syndrome, are becoming an epidemic. We aimed to investigate the prevalence of fatty liver and significant fibrosis and examined the independent factors for these conditions. SUBJECTS AND METHODS: We enrolled 1,361 health check-up examinees (median age, 53 years; female/male, 813/548). Fatty liver and fibrosis were evaluated by B-mode ultrasound imaging and shear wave elastography. Factors associated with fatty liver and significant fibrosis were analyzed by logistic regression analysis. RESULTS: Fatty liver and significant fibrosis were observed in 50.5% and 42.7% of enrolled subjects, respectively. Independent factors associated with fatty liver were BMI (OR 1.46; 95%CI 1.397-1.537; P<0.0001) and no exer cise habits (OR 1.47; 95% CI 1.101-1.984; P=0.0093). Independent factors associated with significant fibrosis were age, female, BMI (OR 1.37; 95%CI 1.311-1.436; P<0.0001), and no exercise habits (OR 1.49; 95% CI 1.102-2.031; P=0.0097). CONCLUSIONS: Fatty liver and significant fibrosis were frequently seen in health check-up examinees and the common independent factors were higher BMI and no exercise habits. Thus, weight loss and exercise may ameliorate fatty liver and significant hepatic fibrosis in the general population.

ABSTRACT

AIM: Advanced hepatic fibrosis is seen in individuals with potential hepatocellular carcinoma and cardiovascular disease. Hepatic fibrosis can be assessed using a combination of the FIB-4 index and imaging modalities, including shear wave elastography. We aimed to investigate the prevalence of advanced fibrosis in the general population and the profiles associated with advanced fibrosis using a data-mining analysis. METHODS: We enrolled 1155 health checkup examinees (median age 53 years, 685 women, 470 male). Advanced fibrosis was defined by FIB-4 index ≥1.3 and liver stiffness ≥8.07 kPa using shear wave elastography. Participants were classified as normal-mild fibrosis (n = 1035) or advanced fibrosis (n = 120). Factors associated with advanced fibrosis were analyzed by logistic regression and decision-tree analyses. RESULTS: Advanced fibrosis was observed in 10.4% of participants (120/1155). In the logistic regression analysis, independent factors for advanced fibrosis were age (≥75 years; OR 2.12, 95% CI 1.021-4.415; P = 0.0419) and the presence of metabolic syndrome (OR 2.51, 95% CI 1.416-4.462; P = 0.0017). The decision-tree analysis showed two profiles associated with advanced fibrosis: profile 1 - individuals aged ≥65 years with metabolic syndrome and mild-to-moderate alcohol consumption (prevalence of advanced fibrosis 73.3%); and profile 2 - individuals without metabolic syndrome, aged ≥75 years, with no exercise habit (prevalence of advanced fibrosis 56.3%). CONCLUSIONS: Advanced fibrosis was observed in 10.4% of health checkup examinees. Furthermore, we showed that aging, metabolic syndrome with mild-to-moderate alcohol consumption, and physical inactivity were associated with advanced fibrosis. Thus, prevention of metabolic syndrome and alcohol withdrawal, as well as exercise habits, might inhibit the progression of hepatic fibrosis.

ABSTRACT

Catheter ablation is a common treatment for ar- rhythmia and the number of procedures is increasing. Takatsuki General Hospital introduced a remote mag- netic navigation system into clinical practice for the first time in Japan. This system produces- magnetic flux density of 0.08-0.1 Tesla. Catheter ablation is usu- ally performed under deep sedation at our facility ; however, general anesthesia is needed in some cases. Although many cases of general anesthesia for MRI have been reported, there has been no report of gen- eral anesthesia under the unique environment of a weak magnetic field. We use MRI-certified equipment such as an anesthesia machine and a patient monitor in the heart rhythm center. There is no contraindication for the selection of anesthetic agents. Analgesia, depending on pain or burning sensation by ablation, and immobilization are required. Anesthesiologists must be aware that there are some differences in gen- eral anesthesia in the MRI room compared with the heart rhythm center, including the environmental set- ting, limitations in the use of certain medical equipment and procedure-related knowledge.

ABSTRACT

Atrial arrhythmia is an important prognostic factor in patients undergoing the Fontan operation. Although catheter ablation is considered to be a curative treat- ment the anatomical constraints produced by extra- cardiac total cavopulmonary connection make it diffi- cult to insert catheters towards the right atrium. Mag- netic navigation systems enable safer catheter delivery to the target site in such cases. Catheter ablation was carried out under the guidance of a magnetic naviga- tion system after the Fontan conversion operation in a 39-year-old female patient with persistent atrial tachy- cardia for the first time in Japan. During a 3-hr period of atrial tachycardia (AT), the patient's hemodynamic status was severely compromised ; her systemic blood pressure fell below 80 mmHg, and her central venous pressure increased to 26 mmHg. After the termination of AT, the patient's hemodynamic status was normal- ized without any complications. The procedure was successful, and the patient was discharged as sched- uled. The number of catheter ablation procedures in patients with arrhythmia after the Fontan procedure is expected to increase as patients with complex congen- ital heart defects are surviving longer. It is important to clarify the issues associated with this procedure and establish a safe anesthetic management strategy based on hemodynamic data.

ABSTRACT

The ex-utero intrapartum treatment (EXIT) is a rare procedure, and often comes as an emergency surgery. A careful preparation is crucial and a multidisciplinary team discussion during the prenatal period is necessary because it may be practically and ethically difficult to plan a surgical treatment for a fetus for EXIT. An elective caesarean section and EXIT for a fetus with a giant cervical tumor, which may cause airway obstruction and difficult intubation, were scheduled. The anesthesiologist tried oral intubation by direct laryngoscope; however, neither blade nor rigid bronchoscope insertion was impossible as a firm mass protruded in oral cavity from the left side. Tracheotomy was successfully performed and the airway was secured. As for maternal anesthesia, adequate uterine relaxation was obtained by inhalational agents and nitroglycerine. After ligation of the umbilical cord, anesthesia was maintained with propofol and fentanyl, and good uterine contraction was provided by infusion of oxytocin. The duration of EXIT was 44 minutes. The fetal tumor, containing both solid and cystic components, was 14 centimeters in diameter, and infiltrated into intracranial space. There was no indication of resection nor chemotherapy for the tumor. Palliative care was selected, and the neonate died forty days after birth.

ABSTRACT

Most drugs used in practical pediatric anesthesia are off-label. Pediatric anesthesiologists and non-pediatric anesthesiologists who rarely encounter pediatric patients need to be aware of the clinical usage of these drugs based on pediatric pharmacokinetics and pharmacodynamics to ensure that children are not exposed to unnecessary risks. Clinical guidelines on anesthetic drugs have been made available on the Japanese Society of Anesthesiologists website, and anesthesiologists are encouraged to access this site at least once. Propofol is commonly used in pediatric anesthesia and sedation in several situations. However, we should always consider the possibility of propofol infusion syndrome in the case of long-term administration. Rocuronium is widely used for general anesthesia in elective surgeries, examinations, and minor procedures in pediatric patients. Rocuronium can be used for rapid sequence induction, taking into consideration the dose and duration of action. Sugammadex has recently been introduced for practice in Japan. Rocuronium and sugammadex have been used safely in pediatric patients so far, and may change the induction methods used in difficult airway patients and the management of airway emergencies. Desflurane is novel in Japan and has not been commonly used in pediatric anesthesia. Desflurane may cause very high irritability in the airway and may be used for the maintenance of anesthesia in limited situations.

ABSTRACT

We report a case of an 8-year-old girl with fulminant myocarditis successfully treated with percutaneous cardiopulmonary support (PCPS). She was first taken to our hospital for treatment of suspected infective enterocolitis since her main symptoms were fever, vomiting and diarrhea. On day 2 after admission, her ECG showed wide QRS and echocardiography demonstrated severe hypokinesis. She was transferred to the ICU with suspected acute myocarditis. On admission to the ICU, circulatory collapse was not detected. ECG showed severe bradycardia and ventricular fibrillation after intubation. Cardiopulmonary resuscitation was performed immediately for 50 minutes prior to initiation of PCPS. She was treated intensively with catecholamines, plasma exchange, continuous hemodiafiltration, high-dose gamma-globulin, and high dose methylprednisolone. Hypothermia therapy was also performed. She was weaned from PCPS on day 6 after initiation of PCPS. The patient was finally discharged from the hospital without any neurological complications on day 68 after weaning from PCPS. The proportion of patients in whom cardiopulmonary resuscitation was performed or having ventricular tachycardia or fibrillation were higher in non-survivors than in survivors.

ABSTRACT

BACKGROUND: There is no study on the use of bicarbonated Ringer's solution (BR) for pediatric patients. We evaluated the effect of BR on infants and children undergoing open-heart surgery, compared with acetated Ringer's solution (AR). METHODS: The records of 18 pediatric patients with congenital heart disease who had undergone elective open-heart surgeries with cardiopulmonary bypass (CPB) were reviewed retrospectively. Eight patients received AR as infusion and CPB priming solution, and ten patients received BR. The pH, HCO3-, base excess and lactate were measured at seven points ; (1) after anesthesia induction, (2) CPB-start, (3) before CPB withdrawal or 60-minute after CPB, (4) after CPB withdrawal, (5) end of operation, (6) 6-hour after operation, and (7) 24-hour after operation, and administered volume of sodium bicarbonate during surgery and 24-hour after surgery were evaluated. Data were compared between two groups. RESULTS: There were no significant differences in values of pH, HCO3-, base excess and lactate between the two groups at any measurement point. The administered volume of sodium bicarbonate during the procedure in BR was significantly smaller than that in AR. CONCLUSIONS: BR was useful as infusion fluid and CPB priming solution for infants and children who underwent open-heart surgeries, and reduced the administration of sodium bicarbonate during surgery.

ABSTRACT

The post-operative pain state results from a barrage of primary afferent inputs exposed to products of tissue damage such as bradykinin and prostaglandins and the central sensitization by the continuing inputs. This provides the rationale for preemptive analgesia, whereby the blockade of primary afferent inputs prior to injury may result in a reduction of post-operative pain. 2-(10,11-dihydro-10-oxo-dibenzo[b,f]thiepin-2-yl) propionic acid (zaltoprofen) is a unique compound that inhibits cyclooxygenase (COX) and exhibits anti-bradykinin activity. The present study evaluated the preemptive analgesic effect of zaltoprofen in a post-operative pain model produced by plantar incision. When orally, but no intrathecally, administered 30 min prior to incision, zaltoprofen significantly increased the withdrawal threshold 2 h and 1-3 days after incision at 10 mg/kg. While the bradykinin B1 antagonist des-Arg10-HOE-140, the selective COX-1 inhibitor SC-560, and the selective COX-2 inhibitor celecoxib did not affect post-operative pain, the B2 antagonist HOE-140 dose-dependently relieved the post-operative pain at 2-200 microg/kg with a time course similar to that of zaltoprofen. The B2 receptor mRNA was expressed in the hindpaw and the expression did not change before and 24 h after surgery. These results suggest that zaltoprofen produces the preemptive analgesic effect peripherally by blocking the B2 pathway.

ABSTRACT

Prostacyclin (PGI2) is well known to play crucial roles in induction of edema and pain behavior in the periphery. In the present study, we investigated the central role of PGI2 in inflammatory pain. Intraplantar injection of carrageenan markedly induced the expression of prostacyclin receptor (IP receptor) mRNA with the maximum at 6 h, coincidently induction of the inducible form of cyclooxygenase (COX-2), although IP receptor mRNA was weakly expressed in the spinal cord of naive mice. Intrathecal administration of the IP agonist cicaprost induced mechanical hyperalgesia 6 h after carrageenan injection. These results suggest that PGI2 is involved in pain transmission at the spinal cord following expression of IP receptor mRNA induced by peripheral inflammation.
