Background:
Ultrasound-guided first sacral transforaminal epidural steroid injection (S1 TFESI) is a useful and easily applicable alternative to fluoroscopy or computed tomography (CT) in lumbosacral radiculopathy. When a needle approach is used, poor visualization of the needle tip reduces the accuracy of the procedure, increasing its difficulty. This study aimed to improve ultrasound-guided S1 TFESI by evaluating radiological S1 posterior foramen data obtained using three-dimensional CT (3D-CT).
Methods:
Axial 3D-CT images of the pelvis were retrospectively analyzed. The radiological measurements obtained from the images included 1st posterior sacral foramen depth (S1D, mm), 1st posterior sacral foramen width (S1W, mm), the angle of the 1st posterior sacral foramen (S1A, °), and 1st posterior sacral foramen distance (S1ds, mm). The relationship between the demographic factors and measured values were then analyzed.
Results:
A total of 632 patients (287 male and 345 female) were examined. The mean S1D values for males and females were 11.9 ± 1.9 mm and 10.6 ± 1.8 mm, respectively (P < 0.001); the mean S1A 28.2 ± 4.8° and 30.1 ± 4.9°, respectively (P < 0.001); and the mean S1ds, 24.1 ± 2.9 mm and 22.9 ± 2.6 mm, respectively (P < 0.001); however, the mean S1W values were not significantly different. Height was the only significant predictor of S1D (β =0.318, P = 0.004).
Conclusions
Ultrasound-guided S1 TFESI performance and safety may be improved with adjustment of needle insertion depth congruent with the patient’s height.

BACKGROUND: The purpose of this study was to compare temperatures measured at three different sites where a nasopharyngeal temperature probe is commonly placed. METHODS: Eighty elective abdominal surgical patients were enrolled. After anesthesia induction, four temperature probes were placed at the nasal cavity, upper portion of the nasopharynx, oropharynx, and the esophagus. The placement of the nasopharyngeal temperature probes was evaluated using a flexible nasendoscope, and the depth from the nares was measured. The four temperatures were simultaneously recorded at 10-minute intervals for 60 minutes. RESULTS: The average depths of the probes that were placed in the nasal cavity, upper nasopharynx, and the oropharynx were respectively 5.7 ± 0.9 cm, 9.9 ± 0.7 cm, and 13.6 ± 1.7 cm from the nares. In the baseline temperatures, the temperature differences were significantly greater in the nasal cavity 0.32 (95% CI; 0.27-0.37)℃ than in the nasopharynx 0.02 (0.01-0.04)℃, and oropharynx 0.02 (−0.01 to 0.05)℃ compared with the esophagus (P < 0.001). These differences were maintained for 60 minutes. Twenty patients showed a 0.5℃ or greater temperature difference between the nasal cavity and the esophagus, but no patient showed such a difference at the nasopharynx and oropharynx. CONCLUSIONS: During general anesthesia, the temperatures measured at the upper nasopharynx and the oropharynx, but not the nasal cavity, reflected the core temperature. Therefore, the authors recommend that a probe should be placed at the nasopharynx (≈ 10 cm) or oropharynx (≈ 14 cm) with mucosal attachment for accurate core temperature measurement.

Lymphangiomyomatosis (LAM) is a rare lung disease that is characterized by the progressive proliferation of atypical smooth muscle-like cells, which leads to severe respiratory impairment and death. Dyspnea, cough, recurrent pneumothorax, and hemoptysis are the most common clinical symptoms of LAM. We report a 29-year-old female patient with massive hemoptysis during laparoscopic gynecologic surgery under general anesthesia, who was diagnosed with pulmonary LAM.

BACKGROUND: A preanesthetic visit can increase a patient's satisfaction. However, it is uncertain whether a preanesthetic visit by an anesthesiology resident can achieve the goal. We studied the time distribution for content of preanesthetic interviews (PI) and evaluated the patient's satisfaction with the PI. METHODS: We recorded the PI duration of 200 patients by a voice recorder. The degrees of patient satisfaction with the PI and the changes of anxiety level after the PI were quantified by a questionnaire. We analyzed the time distribution for content of the PI and the correlation between patient characteristics and PI duration or a patient's satisfaction. RESULTS: The total PI duration was 184 (134-286) sec (median, 25-75%), and the time distributions for content of the PI were 8 (5-10) of greeting, 45 (23-70) of history taking, 15 (10-20) of physical examination, 50 (25-98) for obtainingan informed consent, 20 (10-30) of explanation for anesthetic planning, 15 (5-28) for explanation of patient controlled analgesia, and 10 (0-4) sec for questions and answers. Age, ASA physical status, and educational level were correlated with PI duration (P < 0.001). The patient's level of satisfaction was "very satisfied" in 39%, "satisfied" in 50%, and "moderate" in 11% of interviews. The anxiety level was "decreased" in 50%, "increased" in 8%, and "not changed" in 42% of patients. CONCLUSIONS: Although the duration of a PI given by residents was a relatively short, 89% of patients of were satisfied with the interview. The PI took a longer time to complete in patients of older age, higher ASA physical status, or lower educational levels.

Cardiopulmonary bypass (CPB) is widely used for cardiac surgery by virtue of its proven safety over the course of its use during the past half century. Even though perfusion is safer, incidents still occur. During the repair of a ventricular-septal defect in an 11-month-old infant, we experienced a critical incident related to the potential hazardous effect of volatile anesthetics on the polycarbonate connector of extra-corporeal circuit. The damage to the polycarbonate connector had occurred after spillage of isoflurane during the filling of the vaporizer, causing it to crack and leak. The incident was managed by replacement of the cracked connector during a temporary circulatory arrest. The patient was hypothermic and the time off bypass was less than 1.5 min. There were no neurologic sequelae, the patient made an uneventful recovery. In conclusion, the spillage of volatile anesthetics can cause cracks in the polycarbonate connector of the extra-corporeal circuit, leading to potentially interruption of CPB.

10.A management of a pulmonary thromboembolism patient under monitoring of VigileoTM monitor (pulse contour cardiac output monitor) : A case report.

Pulmonary embolism (PE) is an uncommon but, highly lethal condition that is a leading cause of death. However, prompt diagnosis and treatment can dramatically reduce the mortality rate and morbidity of PE. Unfortunately, the diagnosis is often missed because of vague and nonspecific symptoms. We report a case of pulmonary thromboembolism (PTE) which was developed during surgical preparation for pelvic bone and sacro-iliac joint reduction surgery after induction of general anesthesia. We monitored and treated efficiently the PTE patient under monitoring of VigileoTM monitor (pulse contour cardiac output monitor) in operating room and intensive care unit. After complete resolving of PTE, the surgery was reperformed with VigileoTM monitoring without any complications. We suggest that the VigileoTM monitor is simple and minimal invasive method to monitor the hemodynamic status in management of PTE patient.
