Pharmacological management is the first choice for treatment of the trigeminal neuralgia patients; however, if this mode of treatment fails a minimally invasive procedure should be performed. One of the most commonly used procedures is conventional radiofrequency lesioning of the Gasserian ganglion. Despite its popularity and success rate, this technique has disadvantages such as diminished corneal reflex, masseter weakness, numbness and anesthesia dolorosa. As a result, many studies have been conducted in an attempt to find a better method of treating trigeminal neuralgia. We report here a case of a trigeminal neuralgia patient that was treated with pulsed radiofrequency lesioning of the supraorbital and supratrochlear nerve due to pain in the frontal head that was refractory to the pharmacological treatments. Following the procedure, the Visual Analogue Scale score for pain decreased to 1-2/10 and the pain relief persisted for 7 months. These results indicate that pulsed radiofrequency treatment of the peripheral nerve may be useful for trigeminal neuralgia patients that do not respond to pharmacological treatments.

Placement of a pulmonary artery catheter for hemodynamic monitoring in the operating room or intensive care unit is very useful, but this is associated with various complications. They are rupture of the pulmonary artery, pneumothorax, hemothorax, thromboembolism, hemoptysis, arrythmia, valvular damage, sepsis, rupture of the balloon, entrapment or knotting of the catheter and so on. We experienced a case of perforation of the superior vena cava that was caused by a pulmonary artery catheter during liver transplantation. We diagnosed hemothorax during the operation, and we recognized the perforation by performing thoracoscopy. The perforation site was sutured successfully and there were no more problems.

It is important to treat cancer-related pain in cancer patients to ensure the life quality of the patient, as well as to improve their life span. It has been estimated that at least 5% of cancer patients have pain refractory to medical treatment. Therefore, the need for epidural or intrathecal analgesia with opioids and local anesthetics is indicated if systemic treatment has failed. Intrathecal catheter placement and implantation of the injection port for administration of opioids and local anesthetics may improve pain relief in patients who are unresponsive to epidural routes. Although intrathecal implantation has several complications, similar infection rates have been reported between intrathecal and epidural administration. In addition, intrathecal administration showed better outcomes, including improved pain control, lowered daily doses, and an improvement in the level of drowsiness experienced when compared to epidural administration. We report here a case in which a terminal cancer patient was treated using an intrathecal catheter and subcutaneous port. The patient had cancer-related pain that could not be controlled by epidural opioid administration. Based on the results presented here, we suggest that intrathecal implantation is a feasible long term pain management method for intractable cancer pain patients.

We report a case of difficult intubation due to a low located thyroid cartilage and a left deviated glottis abnormality. A 35-year-old woman was scheduled to undergo a laminectomy and discectomy for a L4-5 disc herniation. After injecting intravenous induction agents and muscle relaxant, intubation was attempted with a direct laryngoscope. However, no vocal cords were seen and only the epiglottis was seen albeit only slightly. According to Cormack and Lehane's grading, the patient was grade III. Although intubation was re-attempted after changing the anesthesiologist and device such as a light wand, the endotracheal tube could not be advanced below the epiglottis because of resistance. When patient was rechecked, her thyroid cartilage was located abnormally low and the thyromental distance was 14.5 cm. In addition, the preoperative chest X-ray revealed her airway to be deviated to the left. Intubation could be successfully performed after additional 100% oxygen mask ventilation. An otolaryngologic examination revealed that the glottic opening was deviated to the left, and ventricle of the larynx, which is normally not seen with a laryngocope was located to the center. It is believed that the reason for resistance of the advancing endotracheal tube was a centrally located ventricle of the larynx.

BACKGROUND AND OBJECTIVES: An increased pulse wave velocity (PWV) and a non-dipping pattern in hypertensive patients have been shown to be associated with an excess of target organ damage. The relationship between the PWV and circadian variation of blood pressure (BP) (dipper or nondipper) were sought, and also the LV diastolic function between dipper and nondipper patients compared. SUBJECTS AND METHODS: 44 hypertensive subjects, who had never been treated, were enrolled (mean age: 48+/-12 yrs, men: 29). The following procedures were undertaken. 1) 24 hour ambulatory BP monitoring; 2) echocardiography for LV geometry, LV mass index (LVMI), LV systolic and diastolic functions, including tissue Doppler and aortic PWV. The patients were divided into two groups with respect to their ambulatory BP profiles, i.e., dipper and nondipper. The PWV, LV geometry and diastolic functions were compared between dipper and nondipper patients, and the relationship between the PWV and diastolic function analyzed in all patients. RESULTS: Twenty (45%) were nondipper patients. There were no significant differences in the LV geometry, LVMI and PWV between dipper and nondipper patients (PWV; 8.8+/-3.1 vs. 8.6+/-3.3 m/sec, p>0.05). In all patients, the PWV was related to the deceleration time (r=0.34, p=0.03) and the mitral E/A (r=-0.31, p=0.02) and mitral Em/Am ratios obtained by the tissue Doppler echocardiography (r=-0.31, p=0.03). The proportion with diastolic dysfunction was higher in the nondipper than the dipper patients (21 vs. 50%, p<0.01). There was a significant relation between the PWV and Em (r=-0.45, p=0.047) in the nondipper, but not in the dipper. CONCLUSION: Prolonged exposure to high BP (nondipper) was not related with increased aortic stiffness in never treated hypertensive patients. The PWV was closely related with LV diastolic dysfunction in nondipper patients.

The aim of this study was to investigate the efficacy of simvastatin to improved lipid profiles in hypercholesterolemic Korean patients. METHODS: From 25 hospitals in Korea, 478 hypercholesterolemic patients were enrolled from November 1996 to April 1998. The inclusion criteria was hypercholesterolemia over 240 mg/dl after diet therapy for 1 month or hypercholesterolemia over 220 mg/dl in patients with definite evidence of ischemic heart disease. Simvastatin 10mg was started and doubled up to 40mg if total cholesterol level remained higher than 200 mg/dl at monthly check. Of 478 subjects, 344 patients in whom study protocol was not violated were analyzed. RESULTS: Male to female ratio was 27:73 and 47% of the subjects were in 6th decade. Hypertension, coronary artery disease, and diabetes mellitus were present in 30, 10, and 4% of the subjects. Baseline lipid profile (mean of total cholesterol-LDL-HDL-triglyceride mg/dl) was 274-185-52-188. The dose of simvastatin for 3 months was 10/10/10mg in 61% of subjects, 10/20/20mg in 21%, 10/10/20mg in 7%, and 10/20/40mg in 12%. The change of total cholesterol level(before-4wk-8wk-12wk-withdrawal 4wk) was 274-209- 205-198-250, and the maximal reduction rate was 27%. The change of LDL-cholesterol was 185-123-116-110-159, with maximal reduction rate 39%. The change of HDL-cholesterol was 52-54-56-55-54, with maximal increase rate 9%. The change of tryglyceride was 188-161- 164-162-189, with maximal reduction rate 15%. The value before/after treatment of ApoA1, ApoB, and Lp(a) was 129/129, 138/83, and 9.3/10.7, respectively. The level of LDL-cholesterol at the end of treatment was below 100mg/dl in 36% of subjects, 100-130 in 45%, 130-160 in 16%, and over 160mg/dl in 4%. The reduction rate of LDL-cholesterol was different between subjects whose LDL decreased below 100 and those whose LDL did not decrease below 130mg/dl, which suggests the existence of the individual difference of responsiveness to simvastatin. There were only 3 subjects (0.9%) who showed increase of liver enzyme over 3 times as the upper normal limit. Conclusion: Simvastatin is effective in improving lipid profiles in hypercholesterolemic Korean patients without serious side effects.

Subcutaneous emphysema is one of the rare complication of tracheal intubation and it's mechanism has been known as airleakage to subcutaneous tissue from the perforated site of larynx, trachea and esophagus by the trauma of laryngoscopic blade, stylet and endotracheal tube. We experienced a case of subcutaneous emphysema during unexpected difficult endotracheal intubation. At the initial laparoscopic examination, the patient's laryngeal view was grade IV of Cormack and Lehane's calssification. After several trial of the intubation, cervical subcutaneous emphysema developed by the trauma of laryngoscopic blade, stylet and endotracheal tube, even though failed to confirm the perforated site at postanesthesia one day.

BACKGROUND: Combined spinal epidural anesthesia (CSE) is used for obtaining adventages of both spinal and epidural anesthesia. But it might be suspected that epidural volume load affect spinal sensory blockade level during CSE. METHODS: Eighty patients undergoing lower abdominal and lower extremity operation were involved in our study. Subarachnoid block with 12mg of tetracaine was established in all patients. Four groups were studied. Group 1 (n=20), the control, received only spinal anesthesia. Group 2 (n=20), group 3 (n=20) and group 4 (n=20) received 10, 15 and 20 ml of epidural saline immediately after spinal anesthetic administration. Sensory blockade level was checked by pinprick test at 5, 10, 15, 20, 25, 30, 40, 60 and 90 minutes. Blood pressure, heart rate and incidence of complications such as hypotension, bradycardia, nausea and high block were measured. RESULTS: The sensory blockade level of groups 3 and 4 was higher than group 1 (p<0.05). Blood pressure and heart rate were not different compared with each other. The incidence of complications, except that higher block above T4 in group 4 was more than in group 1 (p<0.05), were not different when compared with each other. CONCLUSIONS: Epidural saline above 15 ml may affect sensory blockade level of spinal anesthesia during CSE.
