BACKGROUND: We postulated that loss of epidural negative pressure might affect on the sensory blockade level of spinal anesthesia. METHODS: Thirty nine patients were involved in our study; group 1, spinal anesthsia with 23G spinal needle (n=20): group 2, spinal anesthesia with 27G spinal needle through the 18G Weiss epidural needle (n=19). Sensory blockade level was checked by pinprick test at 5, 10, 15, 20, 25, 30, 40, 60 and 90 minutes after spinal anesthesia. RESULTS: There was no difference of sensory blockade level between group 1 and 2. CONCLUSION: From above result, there was no evidence of loss of epidural negative pressure affecting on the spinal sensory blockade level.

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.

PURPOSE: The aim of this study was to elucidate the current incidence of varicoceles in unselected Korean children and adolescents. MATERIALS AND METHODS: 4271 Korean school boys aged 7-18, resided in Namhaegun, Gyungnam province were investigated. The study population comprised more than 95% (4271/4403) of all boys in the respective age in a rural country with a total population of 61,820 (29,840 males and 31,980 females). All examinations were carried out by a single urologist from March to June 2000. The patients with varicocele were divided according to the classification of Dubin-Amelar. RESULTS: No case of varicocele was encountered in 1,233 boys between 7 to 10 years, while the incidence in the 3,038 boys aged 11 to 18 years was 9.61% (292 boys). There was a peak varicocele incidence from aged 14 to 16 (11.78-13.52%). The proportion of varicocele grades were grade I 21.58% (63/292), grade II 44.68% (131/292), grade III 33.56% (98/292). There were 2 cases of bilateral varicoceles. Other abnormalities found were 7 cryptorchidism (0.16%) and 27 hydroceles (0.63%). In 33 older boys (aged between 16-18) with varicocele, semen analyses were performed and two boys had subnormal sperm concentration. CONCLUSIONS: Our finding of peaking at ages 14 to 16 was parallel with the old Danish report,11 but our incidence was substantially lower than the report of 16.2%.

Amniotic fluid embolism (AFE) is a rare but devasting obstetric emergency. We experienced a case of AFE during dilatation and curettage (D & C) in a 15 2/7 weeks pregnant woman, age 30, who was diagnosed as having a missed abortion. Sudden rapid hypoxemia, low SpO2, hypotension, low PETCO2, high CVP, and tachycardia, right axis deviation and right bundle branch block in 12 leads ECG were developed during D &C under general anesthesia, and signs of disseminated intravascular coagulation (DIC) followed after the operation, which are consistent with the findings of AFE. Even though there was no definite pathologic and radiologic confirmation of AFE, laboratory findings showed 100 times higher level of alpha-fetoprotein in her central venous blood than same weeks of missed abortion woman's blood. Though it is rare, the anesthesiologist should always suspect the possibility of AFE, when the patient shows an unexplained collapse, cyanosis, low PETCO2, high CVP, low SpO2, ECG change and DIC during any kind of obstetric procedure.
