Background: Positive end-expiratory pressure(PEEP) ventilation causes reduction in cardiac output and increase of intra-thoracic pressure, hence reduction of hepatic blood flow. The purpose of this study is to evaluate the changes of hepatic venous oxygen saturation, tension and content during increase and removal of PEEP and to evaluate hemodynamic variable which has the greatest effect on hepatic oxygenation. Method: Eight dogs were anethetised with 1.0 vol% isoflurane and 100% oxygen. After 30 minutes of stabilization of vital signs, PEEP were increased from 0 cmH2O to 5 cmH2O and 10 cmH2O and lowered to 0 cmH2O again, and hemodynamic data (heart rate, arterial blood pressure, central venous pressure(CVP), pulmonary arterial pressure, pulmonary arterial occlusion pressure and cardiac output(CO)) and hepatic venous oxygenation data (hepatic venous oxygen saturation(ShvO2), tension(PhvO2) and content(ChvO2)) were measured at each step. Results: CO, ShvO2, PhvO2 and ChvO2 decreased significantly at 10 cmH2O PEEP compared to the baseline and 5 cmH2O PEEP and CO, ShvO2 and ChvO2 increased signicantly with removal of PEEP. CVP increased significantly at 10 cmH2O PEEP and decreased significantly with PEEP removal. PEEP showed close correlationship with CO and CVP considering all steps of PEEP and PEEP removal. ShvO2 and PhvO2 showed most close correlationship with CO considering all steps of PEEP and PEEP removal. Conclusion: ShvO2 with PEEP therapy is dependent upon CO. Therefore cardiac output maintenance is essential during PEEP therapy. For exact evaluation of hepatic oxygenation, it is valuable to monitor ShvO2.

The author evaluated 63 patients(95 eyes) of congenital blepharoptosis whowere operated by frontalis sling and external levator resection at the Keon Yang Medical Foundation Kim's Eye Clinic. To obtain the best results in blepharoptosis, it is necessary to evaluate degree of levator function, amount of ptosis and its etiology. The results are as follows: 1. The majority(78%) were operated at the age between the first and the second decade. 2. Levator function of congenital ptosis was poor(under 4mm) in 84 eyes and fair(5~7mm) in 11 eyes. 3. The author obtained good surgical result in 20 eyes(80%) by frontalis sling and in 35 eyes(92%) by external levator resection. 4. Most common complication was undercorrection(8 cases). 5. External levator resection is the primary choice of operation for ptosis with poor levator function(3~4mm).
Blepharoptosis*

The surgical treatments of blepharoptosis by resection of the levator palpebrae superioris(LPS) muscle and levator aponeurotic repair, Fasanella-Servat procedure have occasionally complication like as overcorrection, especially in acquired cases. The recession of levator palpebrae superioris(LPS) muscle (anterior recession and posterior tenotomy) and/or marginal myotomy had been performed on 6 overcorrected blepharoptotic patients from November, 1987 to July, 1990 in Keon Yang medical foundation and the results were satisfactory.

Moderate to severe unilateral ptosis has previously been treated with levator resection or frontalis sling and cosmetic double fold in the opposite eyelid. This method often resulted in undesirable asymmetrical lid lag phenomenon in down gaze. From December 1991 to December 1994, we treated 65 cases of unilateral ptosis with frontalis sling or levator resection, and simultaneously cosmetic frontalis sling have been performed in the unaffected normal eyes of 41 patients and cosmetic double fold have been performed in the unaffected normal eyes of 11 patients. After 6 months of operation, authors survey the patients content. The number of cases of content were 4(36.36%) in 11 cosmetic double fold group and 31(75.6%) in 41 cosmetic frontalis sling group. The content after cosmetic frontalis sling was higher than cosmetic double fold. Asymmetrical lid lag phenomenon on downward gaze which is inevitable complication postoperatively was reduced by means of cosmetic frontalis sling of unafeected normal eye in unilatral ptosis. The authors expect that the patient will be more satisfied with the result of symmetrical lid lag in down gaze after cosmetic frontalis sling of unaffected normal eye in aesthetic aspect.
