AIM:To establish the frequency of hyperphosphate-mia following the administration of sodium phosphate laxatives in low-risk patients. METHODS:One hundred consecutive ASAⅠ-Ⅱindividuals aged 35-74 years,who were undergoing colonic cleansing with oral sodium phosphate(OSP) before colonoscopy were recruited for this prospective *** criteria:congestive heart failure, chronic kidney disease,diabetes,liver cirrhosis,intestinal obstruction,decreased bowel motility,increased bowel permeability,and *** day before colonoscopy,all the participants entered a 24-h period of diet that consisted of 4 L of clear fluids with sugar or honey and 90 mL(60 g)of OSP in two 45-mL doses,5 h *** phosphate was measured before and after the administration of the laxative. RESULTS:The main demographic data(mean±SD) were:age,58.9±8.4 years;height,163.8±8.6 cm; weight,71±13 kg;body mass index,26±4;women, 66%.Serum phosphate increased from 3.74±0.56 to 5.58±1.1 mg/dL,which surpassed the normal value (2.5-4.5 mg/dL)in 87%of the *** highest serum phosphate was 9.6 mg/*** and creatinine remained within normal ***-treatment OSP se-rum phosphate concentration correlated inversely with glomerular filtration rate(P<0.007,R 2=0.0755),total body water(P<0.001,R 2=0.156)and weight(P< 0.013,R 2=0.0635). CONCLUSION:In low-risk,well-hydrated patients, the standard dose of OSP-laxative-induced hyperphos-phatemia is related to body weight.

preoperative considerations, operative preparation,and postoperative care for rib cartilage use in rhinoplasty

引用

Plastic and Aesthetic Research 2019年第3期6卷 26-32页

作者： Jong Sook Yi Dr.Jin's Premium Nose Clinic Seoul 06524South Korea

Rib cartilage is the most reliable material for structural support and dorsal augmentation in Asian rhinoplasty with its robust strength and bountiful amount. Its value is incomparable especially in complex, cartilage-depleted revision surgery or major reconstruction. There are many articles regarding harvesting and carving of rib cartilage in rhinoplasty,however, only few has focused on preoperative and postoperative issues. preoperatively, evaluating cartilage availability, assessing quality and quantity of cartilage, and choosing the cartilage to harvest are necessary. Although easily overlooked, proper postoperative management of rib cartilage rhinoplasty patients is key to prevent infection and heighten patient satisfaction. Here in, I would like to introduce how I evaluate rib cartilage rhinoplasty patients preoperatively and manage them postoperatively to maximize the surgical results.
