Video-assisted thoracic surgery (VATS) has been increasingly used because of it is a less invasive procedure than the open thoracotomy. Neither commercially available double-lumen tubes nor the univent tube can be used in small children. An ordinary uncuffed tracheal tube was introduced into the main bronchus of the right lung. This technique proved to be a simple and effective method of isolating and ventilating the other lung. We describe our experience providing one-lung ventilation with ordinary endotracheal tube during VATS in two young children. (Korean J Anesthesiol 2001; 40: 824 ~ 828)

BACKGROUND: The efficacy of epidurally administered tramadol hydrochloride, a weak centrally acting analgesic, was studied for the relief of postoperative pain. Clonidine, an alpha2 adrenergic agonist, has nonopiate antinociceptive properties which might be an alternative for postoperative analgesia free of undesirable effects from opioids. The aim of this study was to evaluate the postoperative analgesic effects of an epidural administration with a combination of tramadol and clonidine. METHODS: Sixty patients undergoing lower abdominal surgery were randomly allocated to three treatment groups to be given the following agents by the epidural route: group 1, 10 ml of bupivacaine 0.125%; group 2, 10 ml of bupivacaine 0.125% with tramadol 50 mg; group 3, 10 ml bupivacaine 0.125% with tramadol 50 mg and clonidine 100 microgram. In the recovery room, postoperative analgesia was assessed by the visual analogue scale (VAS) at 30 min, 1, 2, 3, 4, 5 and 6 hour. Vital signs, sedation score and side effects were also checked. RESULTS: VAS scores were significantly lower in group 3 than group 1. In addition, VAS scores were significantly lower in group 3 than group 2 at 4 and 5 hours. Blood pressure, heart rate and sedation scores were not significantly different among the three groups. CONCLUSIONS: The combination of epidural 0.125 % bupivacaine, tramadol 50 mg and clonidine 100 microgram produces more profound and longer postoperative analgesic effects than 0.125% bupivacaine and tramadol 50 mg or only 0.125% bupivacaine for the lower abdominal surgery.

Dental practice can produce and spread some infetious diseases from patients to dentist, dental assistant, and dental labors. One possible method for preventing these cross-contamination is to immerse dental impression in chemical disinfectants. So far many investigators studied on the dimensional changes of dental impressions and on the surface qualities of stone casts made from impression following immersion in disinfectants. This study was proposed to evaluate some popular impression/disinfectant combination from the point of dimensional stability. Impression was taken from dental arch-shaped metal model. Irreversible hydrocolloid and 3 elastomers(polyvinyl siloxane, polysulfide, polyether) were immersed in 3 disinfectants (2% glutaraldehyde, 1% povidone-iodine, 0.5% sodium hypochlorite) for 10 minutes and measured both cross-arch and anterior-posterior distance under stereo microscope to evaluate dimensional change. The results obtained were as follows: 1. Dimensional changes of irreversible hydrocolloid impression was statistically different in crossarch and anterior-posterior distance when immersed in 2% glutaraldehyde solution and in anterior-posterior distance when immersed in 0.5% sodium hypochlorite solution from control group(p<0.05). 2. Dimensional changes of polyvinyl siloxane and polysulfide impression were not statistically different from control group (p>0.05). 3. Dimensional changes of polyether impression was statistically different in cross-arch distance when immersed in 0.5% sodium hypochlorite solution and in anterior-posterior distance when immersed in 1% povidone-iodine solution from control group (p<0.05). 4. In all cases, dimensional changes were less than 0.1% from the original dimension and concluded clinically acceptable

PURPOSE: Platelet Rich Plasma(PRP) application is increasing with sinus inlay bone graft, but there is few research with radiographic ananlysis on effect of PRP in maxillary sinus. The author investigated the amount of bony changes of maxillary sinus for dental implantation among the patients with maxillary inlay graft. MATERIALS AND METHODS: With 10 patients who were treated with sinus inlay autologous bone grafting combined with PRP technique, and with 5 patients who were treated with sinus inlay grafting only without PRP, the panoramic radiographys which were taken at preoperation, immediate postoperation, 3months postoperation, and 4 months postoperation(a month after dental implantation)periods were analysed. The films had been scanned, and then proceeded throughout image analysis system. The bone density of maxillary grafted sites was compared with adjacent tooth enamel density and remeasured according to density luminosity of each film. The density changes on PRP group and bone graft only group were an lysed with non-parameteric statistics method. RESULTS: In PRP combined patients group, bone density on postoperation periods was increased totally. The remarkable enhanced change of bone density was observed on 3 months postoperation period, thereafter the increasing rate was slightly reduced . In only bone graft patients group, bone density on postoperation periods was also increased compared with preoperation period, but the bone density of 4 months postoperation period was decreased compared with 3 months postoperation period. The amount of bone density on PRP group was significantly changed according to periods in contrast to bone graft only group. CONCLUSION: The bone density on PRP group was remarkably increased at 3 months postoperation compared to bone graft only group and it was seemed to be associated with more new bone formation, less grafted bone resorption at bone grafted sites with PRP.
