作者研究了41例上颌、口腔、下唇的恶性肿瘤病人的基础代谢。这些病人的年龄从33—78岁,男性28,女性13。所有病人都是在术前5—7天清晨空腹、精神和肌肉完全安静的条件下,室温在20—22°之间来测定。28个病人术后3—4小时,1、3、7和14天也做了基础代谢的测定。其正常值定为100±10%。研究的结果:在测定的41人中,术前15个病人基础代谢的水平增加了20—25%、5个病人降低、21个病人属于正常范围。作者的资料表明:局限性肿瘤对病人基础代谢的状况影响不大。由于面颌部恶性肿瘤而进行根治性手术后的病人,基础代谢发生明显变化。根治性手术后最初的3—4小时,基础 The authors studied the basal metabolism of 41 patients with malignant tumors of the maxilla, oral cavity, and lower lip. These patients ranged in age from 33 to 78 years old, 28 men and 13 women. All patients were measured at room temperature between 20-22°C under conditions of fasting, mental and muscular complete quiet in the early morning 5-7 days before surgery. 28 patients were also measured basal metabolism 3-4 hours after surgery, 1, 3, 7 and 14 days after surgery. Its normal value is set at 100±10%. The results of the study: Among the 41 patients measured, the basal metabolic levels in the 15 patients before surgery increased by 20-25%, 5 patients decreased, and 21 patients belonged to the normal range. The authors’ data show that localized tumors have little effect on the basal metabolism of patients. Patients undergoing radical surgery due to malignancy of the maxillofacial region undergo significant changes in basal metabolism. The first 3-4 hours after radical surgery, the basis
