BACKGROUND: The purpose of this clinical study was to evaluate the Incentive Spirometry (IS) and Deep Breathing Exercises (DBE) to prevent postoperative pulmonary complications after abdominal surgery in patients over 60 years of age. METHODS: We prospectively randomized 90 patients into 1 of 3 groups: the control group (30 patients) received no respiratory treatment, the IS group (30 patients) was treated with incentive spirometry 4 times daily and DBE group (30 patients) carried out deep breathing exercises under supervision for 15 min 4 times daily. ABGA was taken at ward, PR (preop.room), RR (recovery room), POD1 day and POD2 day. Roentgenographic changes observed at 24 h. and 48 h. after surgery. Pulmonary complications were defined as the development of 3 or more of 6 new findings: cough, sputum, dyspnea, chest discomfort, temperature greater than 38oC, pulse rate more than 100 beats/min. RESULTS: PaO2 in the DBE group and IS group at PR were significantly increased than the values at ward, and the values of the PaO2 in the DBE group at RR and POD1 day, and those of IS group at PR and POD2 day were significant higher than those of the control group (p<0.05). The frequency of development of pulmonary complications (43.3% in the control group, 20% in the DBE group, 20% in the IS group) and roentgenographic changes were comparable in the 3 groups (26.7%, 16.7%, 20% respectively). The DBE group showed the different incidence of postoperative pulmonary complications between upper and lower abdominal surgery (upper: lower= 35.7: 6.3%). CONCLUSIONS: We concluded that DBE and IS were effective in preventing postoperative pulmonary complications after abdominal surgery and lower abdominal surgery causes lesser postoperative pulmonary complications than upper abdominal surgery.

Vascular leak syndrome(VLS) is characterized by endothelial damage, which causes extravasation of plasma proteins and fluid from capillaries into the extravascular space. It has been suggested that the increased vascular permeability is the result of an IL-2-induced suppression of endothelin-1 secretion by endothelial cells, an IL-2-induced activation of the complement cascade or TNF-alpha release from IL-2-activated T-cells. A 13-year-old male patient visited our hospital with abdominal pain. He was diagnosed with acute lymphoblastic leukemia(T cell type) by bone marrow study on his 2 nd day in hospital. On the 3 rd day of induction chemotherapy(prednisone, L-asparaginase, vincristine, intrathecal methotrexate), pulmonary edema and pleural effusion, ascites and generalized edema developed and lasted for 53 days without responding to supportive care. The laboratoy finding was that TNF-alpha was increased without evidence of infection and hypoalbuminemia was noted. It was suggested that the patient's clinical feature was induced by VLS.

STATEMENT OF PROBLEM: It is not clear how to make a stable bonding between zirconia ceramic and resin cement. And the study about surface treatment of zirconia ceramic or bonding resin cement are not enough. PURPOSE: To measure and compare the shear bond strength of some resin cements on zirconia ceramic after different surface treatments. MATERIAL AND METHOD: 48 ceramic discs were made of 3 ceramic materials, zirconia ceramics Zi-Ceram), heat-pressed ceramics (IPS Empress 2) and slip cast alumina ceramics (In-Ceram). According to the surface treatments of ceramic specimens and resin cements, specimens were classified into 6 groups and each group was composed of 8 specimens. For the surface treatment of Zi-Ceram group (test group), sandblasting and diamond bur preparation were applied and Superbond C&B and Panavia F were bonded respectively. For IPS Empress 2 group (control group), Variolink II was bonded after sandblasting, acid etching, silanization and for In-Ceram ALUMINA group (control group), Panavia F was bonded after sandblasting. After storing specimens in distilled water for 24 hours, the shear bond strength was measured by the universal testing machine. RESULTS AND CONCLUSION: 1. Zi-Ceram group with Superbond C&B cement showed higher bond strength than with Panavia F cement regardless to the surface treatments (p<0.05). 2. In Zi-Ceram group with Superbond C&B cement, sandblasting treatment group (12.1MPa) showed higher bond strength than diamond bur treatment group (7.7MPa) (p<0.05). In Zi-Ceram group with Panavia F cement, there were no significant differences in the bond strength according to the surface treatments (p>0.05). 3. Zi-Ceram group with sandblasting and Superbond C&B cement (12.1MPa) showed the highest bond strength. The bond strength of this group was not significantly different from In-Ceram ALUMINA group (10.4MPa) (p>0.05) and lower than IPS Empress 2 group (15.9MPa) (p<0.05).

We experienced a case of postoperative quadriparesis secondary to operative position in a patient with pre-existing, asymtomatic,cervical neurilemmoma. The patient was admitted with chronic otitis media for mastoidectomy on right side. There was no specific event throughout operation and anesthesia but developed quadriparesis one hour after arrival on ward. With magnetic resonance imaging, the patient was dignosed to have cervical neurilemmoma. On seventh postoperative day the patient had second operation,cervical laminectomy and tumor removal. Ten days after second operation he was discharged without any complication. Eight months later he had mastoidectomy on the left side and was discharged without any sequale.

Dextran 40, a polysaccharide with molecular weight of 40,000, has been used clinically for expansion of plasma volume, improvement of microcirculation in low flow states and thromboprophylaxis especially in major operation such as vascular and hip surgery. However severe anaphylactoid reaction to dextran 40 can occur rarely. We experienced a case of cardisc arrest due to a severe reaction of dextran 40 in a patient who underwent aortofemoral bypass surgery. The patient was resuscitated immediately and followed up carefully.

An anesthesiologist should keep in mind the various risk factors during anesthetic man- agement of geriatric patients. Unlike young patients, elderly patients may manifest more than one pathophysiologic process associsted with progressive degenerative changes in various organs. The successful anesthetic management requires detailed information about the cause and severity of the underlying disease, thorough understanding of geriatric specific hemodynamic particularities, and more careful monitoring by experienced personnel. We experienced a case of profound hypotension during general anesthesia for vaginal hysterectomy in a 67 year-old female patient. Anesthesia was induced with thiopental-vecuronium and was maintained with nitrous oxide, oxygen and enflurane. One hundred and five minutes after the induction, profound hypotension and bradycardia with S-T segment depression developed without specific events and were corrected by vigorous therapeutic managements. She discharged from the hospital on 7th postoperative day without complications.
